Sudden signal problem - Galaxy S II Q&A, Help & Troubleshooting

i thought this would be the best place for a problem i started having about2 weeks ago. i am on vodafone uk.
i used to get 3-4 of the 4 bars reception while sitting at home(as an example). suddenly i was getting 1-2 and sometimes none (all blank).
i thought i would try and eliminate things one by one so here is what i did...
checked with my sim in another phone and another sim in mine. from memory the other phone having my sim was slightly down but not much and my phone with the other sim didnt really change much.
i checked with vodafone by calling them, they said they couldnt see any problems on the network, birmingham uk, but would send a new sim, after getting the sim activated when it arrived, no better. their onling forum is still waiting for a response back from their technical whether there is any problems. i dont see how the phone department can instantly tell me when the technical need many days to find an answer.
i thought it could be the rom so i first updated lite'ning rom to resurrection remix and then to a later version of RR and no change. the newest version of RR has a different kernel, flux i think, than the siyah in the 2 previous roms but again that different kernel didnt improve it. lastly i even changed the modem/radio trying to different ones to the default, xxlpx and kh3 and again no difference.
the only thing that improves it is turning 2G on instead of 3G. the bars go back up to 3-4. even with 3G on previously as i never changed it before it was always fine.
i know this is a long post but i wanted to be thorough as i really appreciate any help as i am now lost as what could improve this.

Mispost

anyone?

I have been having a similar problem on Three for about five weeks now. Despite numerous reloads of Android and modems etc I was getting no results, 5mb dl speeds have dropped to around 150kb despite having a good signal.
After many many calls to so called customer service I have discovered that a new cell tower near to me has been activated as part of the network expansion program and because this cell is closer to me than the one I used to connect to I now get a stronger signal from this so my phone always chooses this. Problem is this cell has only got a 2mb feed INTO it, its a TMobile/Orange cell now being shared with Three....so I am basically fooked.
Check with Vodafone if they have done anything similar recently near you. Three are adamant there are no problems my end, technically they are correct I suppose, its all working, I just cant access the net without it timing out constantly now.

I am having the same issue with my phone. I get only one bar (sometimes none!) whenever I'm home & I'm on WiFi; however, I get full signal strength when I'm out & on 3G.

i thought it could be the cell tower thing as there is only 1 vodafone one in quite a large radious, about 2 miles, and many of all the other networks. i dont know why vodafone are happy to have 1 compared to at least 3-4 each for all other providers.
this morning i drove that 1 mile to the vodafone mast and ran fresh network and surely that would have connected to that as i was 5 meters from it. still no better. ??

Just try NELP3 modem once... I had done similar issue once.. Now my network is better..

is nelp3 okay for uk though?

Try flashing another Modem. Im from Germany but i had similar problems. A new Rom would do too i think

not sure what you mean with 'all'

Number of options, tower may be having problems, maybe some form of interference, try a different modem, try different sum card if you have one spare?

i do have the same problem as above, no signal in the building and 50% signal outside building. I swithch my SIM with fren's (he use another telco), and his SIM not work on my S2 and my SIM work on his phone (not SIM issues).
I tested many modem as recommented , LP2/LP3, LP9, LPX, KI3, KI4, KF2, no luck.
I flash different ROM, (some old version that work before), from CM9, AOKP, Sammy. no luck.
I restore old back up ROM. no luck
Fix permission, no luck.
any advice ?

OK next step is to flash a different modem
Sent from my GT-I9100 using xda app-developers app

i've tried a few modems including the ones people believe better, all have this problem so far.
it may be the network mast in my case. i discussed with vodafone what 3G mast i was connected to and then which 3G mast is next closest. i then went right next to that other 3G mast and the signal was full bars, no fluctuation at all. this surely means it is either, 1-the network mast i keep locking to having problems or 2-all the modems i have used favouring battery over strength and not getting enough power to get a good signal.
is there a way of finding out which modems are better for battery and which are better for signal strength?

Umm not that I know of, best thing to do for that is either research the modems for better strength or battery etc, or just test some yourself, however that is time consuming,
Personally I think it is just the mast having problems, however I may be wrong
Sent from my GT-I9100 using xda app-developers app

i thought i would add a little research to this thread, not too much but just my experience with 3 specific modems.
the background is that recently i have started getting very poor network signal as i believe the closest 3g mast to me is having problems. if i turn to 2g its better as the phone then connects to the closest 2g tower which gives better network signal.
i know that a modem should be left for 2-3 days before judging but i thought that if a modem is currently better than another then that is only likely to stay the same with time as long as they were given the same short period of time.
i used the app network signal info and did 3 5 minute tests for each modem and then averaged the percentage of the signal and also averaged the -dbm also.
i first used the modem i currently had on there, BUKI1
- average percentage was 19%
- average -dbm was -103
both very poor scores
the signal was very jumpy up and down also
i then flashed the custom modem, i think by krs007, M250S
- average percentage was 44.6%
- average -dbm was -90.66
obviously a huge increase
the signal was very steady, hardly changing from that average
lastly i flashed NELP3
- average percentage was 30.66%
- average -dbm was -97.33
better than at first but not as good as M250S
i am now going to let M250S bed in for a few days while keeping my eye on here for how NELP4 performs but so far i have a huge increase in signal in a previously very poor area. as this is also due i believe to the tower having problems, hopefully it will only get better.

Try downloading OpenSignalMaps from Google Play Store. For starters, you can determine the approximate location of the offending cell tower (if the cell tower was indeed the culprit). Sometimes, i realise that the phone tends to stick to certain cell towers when others are in closer range and could purportedly provide a better radio link. For this, the app provides a refresh feature that allows you to manually trigger a cell tower refresh. I am aware that most apps requiring connectivity have this feature but i don't suppose you can call the refresh on trigger.

Hi Marc
Tracked down a copy of M250S(dont know if its the same as you have installed though), and very briefly, as in 30 secondsish, I had 4 bars and dl`s around 5mb again!.But midway through it dropped out and that seems to be the pattern. Seems to be having problems locking onto a cell, signal bars frequently grey out, maybe its a compatibility issue with CM9, I dont know.
Anyway, let us know how you get on,
Cheers
Chris

it probably is the same as i dont think any others have that name.
it probably just needs to bed in for a few days. i have noticed mine go between 3g and H quite regular but it always does that, i havent had any dropped calls or similar so far.

[Q] Losing signal on my Amaze 4G

Okay, here is my problem: Every once in a while I will completely lose all signal on my phone. It wont pick up 2G, 4G, nothing. Wifi and bluetooth both seem to work though just fine. I've searched and haven't found anyone with the same issues so I'm wondering if it's just my phone or if nobody has commented on it. I first noticed this about two weeks ago, when my phone refused to find service. I was stuck with the little X next to the signal meter. I figured I was just in an area with poor service and didn't think much of it. An hour later, still, no service. This time I went outside where I know I have good 4G service and nothing for 5 minutes. I enabled airplane mode and disabled it, still nothing. Turned the phone off and back on as a last resort. Still nothing. I ended up finishing the day with wifi calling as that still worked. Sometime later my phone began receiving service again so I thought it was a fluke issue.
Then, just yesterday the same thing happened. This was when I rebooted my phone (which bypasses the fastboot feature) and service was restored right away. I called T-mobile and they said there weren't any network issues in my area and they had never heard of this issue before on the Amaze.
So, this is where I'm asking if anyone has heard of this before. I'm running a stock ROM and it hasn't been rooted. Thanks for any comments!
This might help just a touch. I do live in an area with decent service but my couch and bedroom are deadzones for some odd reason. I bought these signal boosters for 2 bucks figuring "what the hell, I'll give it a shot". No more dead zones, and data went from E to G. Not a miracle worker but for a couple bucks it keeps a signal at least.

Wireless Coverage
I have 2 brand new Amaze 4G for a few months now and had no problem with the coverage. I know the coverage is good with full signal bars and have not found any issue with coverage.
Sometimes, different phones have different received signal sensitivity. Also depends on user behavior. If you are always using a handsfree device (cable or BT) and your phone is in a bag, then your coverage is reduced by your action. The best coverage you can ever get is when you have line of sight (unobstructed) to the cell towers.
There are a few issues with your problem:
1-Poor inbuilding coverage
2-Poor coverage in your area
3-Network optimization issue
4-Hardware issue
If you are going from 1 bar to no bar, then most likely you have coverage issue. You lost signal since the level is already very low.
If you are going from full bar to no bar, you might have hardware or network optimization issue. Try your phone is the city or area with known good coverage first. If the behavior persists, then you have phone problem.
I used to manage wireless network for carriers.
same issue
I've had the exact same thing happen to me. Red x, no signal except wifi, in places where signal is not normally an issue. Battery pull doesn't work, return to signal seems arbitrary. Had the same thing happen with my Desire. I have no answers, but you are not alone.
Yup, it happened with my first Amaze. I got it back in January and started playing with it - rooting, custom ROMs, etc. Then later that day, the signal just died on me. I thought I must've screwed something up, so I flashed back to everything stock. No luck. I waited for half a day, then it randomly started working again at night.
You probably noticed tha tI said that happened with my first amaze. That's because after that signal issue, I discovered that my camera stopped working. I returned it to T-Mobile and they sent me another one. This one is working great though.
Well thank you for all the input so far. Id like to say that this isn't my first cell phone and I'm not new to weak or poor signal areas, especially from T-mobile. I was using my phone at work at the time, which has anywhere from no signal to 3 bars depending on where you are. This wasn't one of the cases that I was standing in a dead zone when I checked my phone. I had no signal for several hours, including over 30 minutes of standing outside trying everything I could think of. I have had excellent signal outside in the past, exactly where I was "Hiding". I got the Amaze because I was tired of playing with my old HD2 and having to work around bugs and possibly not receiving calls. So far, I'm not happy that the radio seems to quit responding all together and leaves me without a phone (minus the wifi calling but I'm not always around a hotspot).
I also experienced a dramatic signal loss at home, going from full signal strength to maybe one bar right around the time that I first had issues. I don't know if this is related or if this is a completely different thing.
I am 99% sure this is an error with the phone - probably software related with the radio driver(s) or radio firmware. I guess I will try taking it back to T-mobile and seeing if they could exchange it for a new one. I was just really wanting to avoid that as I finally got my phone setup how I like it. Again, Thank you for the input and let me know if you are having the same problem or if you know of a solution.
I am on my third Amaze and also tried a Galaxy SII X due to the same problem at my home. Even the Samsung did the same thing. In my house and especially in the driveway, the signal varies wildly between -85dbm to as low as -111dbm. The frustrating thing is once it loses the signal, it doesn't seem to reacquire it without a reboot.
I'm with Telus, and they said they will check on it, but I'm not holding my breath. In my immediate area, outside my house, the signal isn't great, but it will usually hang on. I have been to different cities, and all has been well with it. Coming from a rock steady 2G Touch Pro II, I am disappointed as well..
I am new here to this site, but I am having a similar problem with my Amaze. At work I always have a weak 4G signal, but the last few days it has been gone altogether. I have full phone service (4 bars) but no data. The 4G indicates I have signal, but I can't connect to anything on the web. I called HTC and they had me pull my battery and sim card so they could send a "reset signal" to my phone. After my phone came back up I had faster service than ever, but it only lasted a few minutes and went away again. I am thinking this is a phone issue. Oh, the Amaze is my first Android. My only previous smartphone was my Nokia E71x.
I know if I have WiFi calling selected, an x will show up on my signal if i turn WiFi on. I've personally only had slow data in the area I work. I blame it on the fact that it is a busy corporate park with lots of hotels, cuz my signal is fine elsewhere. Try calling tmobile and seeing if they have known tower issues in your area. I know I had that problem with sprint and they sent me a free airave. Maybe tmobile could do something similar if its.a known problem.

It's most likely a network issue. I get the same thing, it will timeout/refresh the network where it will not get a signal for about 30 seconds a few times per day. I blame the network, since the same thing happened to me with my mt4g

Thank you! This fixed it for me. It was happening only today while I had WiFi enabled, it would turn the mobile radio off completely and the box would be grayed out so I was unable to turn it back on. I had my sim updated today to enable wifi calling so after I read your post, I turned the wifi calling off and the mobile radio signal came back immediately. Strange bug.

I was told It's by design. It saved battery life by not constantly searching for a mobile network it won't use (due to wifi calling). It's not like you can hand off the call to the local network. I do notice that if i start walking outside, once my wifi hits a low signal it logs back on the network.

There is actually an option to specify how the WIFI calling works: either all the time or only when cellular signal is gone. Sounds like you have it set to be on all the time. This means that if you have a good WIFI connection, the cellular radio is shut off and all traffic goes through the WIFI calling app. The other option (which I use) only uses wifi calling when there is no cellular signal.
I have lost cellular signal 3 additional times since my last post. Its not just that I'm in a bad spot and I have no signal for 30 seconds. This goes on for 30 minutes or more - up to several hours. I have found that rebooting the phone fixes it as I believe it completely (as much as possible) removes power from the radio and requires it to be completely re-initiated during the reboot. Simply shutting it off doesn't work as the quickboot is enabled and most likely doesn't perform a complete re-initialization of the radio. My only guess at this point is that there is some kind of possible leftover code from development which never was removed from the radio (this happens more times than not). It could be a timeout or simply causing the radio to hang because of 1. excessive heat generation, 2. excessive power drain, 3. buffer overflow, 4. excessive RF transmit power... In any case, one of those issues could trigger an event in the radio to cause it to simply stop responding.
I am in the process of trying to get T-Mobile to get me a new phone as I am outside of the 30-day window. I have also confirmed it with them that this was not a tower issue.
Thanks

Shoot, I see senior members start new threads or pointless threads without searching first, so good job haha.
Ok, back on topic now, if it's only dropping when you go in your room, then I don't think it's anything wrong with the phone. Not sure who your provider is, but u may be able to call them and have them look up your address and tell you what kind of signal u should get outside your house, and what to expect inside your house. I know t-mobile does at least

Well your situation is a little different than other peoples in this thread if u can't connect al all. Ok wait so first off, it won't connect to a network at all? AND you only paid 50 bucks for it...? Sounds a little fishy to me bud, why did he say he was selling it...?
Next thing, I don't know why a t-mo rep would tell you to root the phone, rooting has no effect on your signal strength or your ability to connect to a network.
And lastly, is the phone a T-Mobile branded amaze owhat carrierr...? and will it not connect at all, period, or can u make calls just not data...?

[Q] Network registration issue?

Hi All,
I am having a strange problem with my S2 since last few months. I am from Mumbai, India and using Airtel network. There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while. It happens that whenever I take my cell in that area, it starts losing signal bars till no bars are highlighted on the status bar at the top. It keeps showing zero bars but does not show "no signal" icon. Then, after keeping my cell in that spot for a while when I bring it in a better connectivity spot, signal bars start increasing and it appears that my cell has better reception again. However, if anyone tries to call me or I try to call anyone, they get "Out of coverage area" message or I get "Network registration failed" message respectively. I am having this problem since the day I started using Airtel and have tried a lot of remedies but only thing that works is rebooting my cell. I have tried using OpenSignal app to reset my connection whenever my cell comes back from the spot but even that fails to revive it and ultimately I have to reboot.
Has anyone faced such an issue and any ideas about a fix? Does it look like an issue with my cell or could it be an issue with my network provider? I would prefer not to root my S2 since I have 3 years warranty on it but if you think that it's the only way out of this, please let me know your opinion.
Thanks.
Sounds like a carrier issue to me. You pretty much said exactly that yourself when you said 'There is a spot in my apartment which has very poor network reception of Airtel and I face issues whenever my cell is in that spot for a while'.
That's normal in many buildings. Particularly if the network coverage in your area is borderline or poor. I have a similar issue in my house, in a few rooms I get no bars & sometimes coverage drops out completely, whereas in my loungeroom/dining/kitchen at the back of the house I get good coverage (for me, anyways).
You could try different modems, which might improve things. You don't have to be rooted to flash these, you can flash them using Odin. Tho it is easier to flash them with CWM if you're rooted.
I use to had the same issue with my 3 carrier at my desk in the office, and still on 2g services. I but since last month they already improved to hsdpa network added more bts and now my blank spot became H.
Yes you may try to change other service providers
Sent from my GT-I9100 using xda premium
Thanks for your suggestions guys. Yes, it might be only related to the carrier. But, I think that if signal goes down to zero and then when my cell is back in better coverage zone, shouldn't the modem take care of network registration by itself? My problem is that it doesn't. I have to reboot my cell every time after I come to know that my cell is showing signal bars but is not actually registered on the network. If I reboot my cell, everything becomes normal and so if it was just an issue with the carrier, shouldn't it continue like that even after reboot? If I think about it logically, I think following should help me out:
1. Try out a different cell for a few days and see if I face this issue or not.
2. If answer to 1 is no, then try out different modems on my S2 and see if that helps.
Actually, I just wanted to check if anyone else has faced this issue and figured out that something is not right with S2 drivers or something? That would help me with quick resolution of my problem.
Sent from my GT-I9100 using XDA
Yep, your logic is sound ;-)
One thing tho. With regard to trying your sim out in another phone, you have to keep in mind the radio hardware is obviously different in different phones. And what that means is (and this is something I've observed on XDA), chances are you'll find the sim works perfectly in the other phone & you have no issues at all. This might be due to the actual equipment your carrier is using in the cell tower(s) you're close to, also the frequencies that gear is using might also be playing a part in your problems.
So definitely try it out in another phone & see what happens, but you could do worse than try out a bunch of modems in the S2 & see if that improves things.

Those are carrier issues, and maybe even the material of the constructions, in my house there are rooms where there's almost no signal at all, and in the living room it's ok, you should try to see in which tower you are connected maybe thats the problem
I have also had these problems on various networks here in Australia. If you don't need the data network, you could try using 2G only option. But that's not really a fix, is it? I suggest you try a pre-paid SIM from another network provider, to test them out first, before re-contracting.
Good luck. :fingers-crossed:

Yes, I was also thinking about it. It could be the combo of cell tower and S2 that are not liking each other that well.. And, if that's the case, I really hope that the issue can be resolved by switching modem drivers. I will have to do some what-ifings to nail this down now.
I like the other suggestion by HotrodHarry on trying out 2G only option - not the best way out but will help me in zeroing down on the cause.

How to increase consistency/strength of the phone signal

My phone - I have ICS - S-OFF Amaze with Energy ROM and I had tried to apply blas0id tweaks.
The problem - In certain areas I don't have phone signal for a few minutes, then suddenly it will show 4 bars for a few minutes. In general the signal seems fickle.
Before ICS upgrade, when I had GB, I always had 4 bars in the same places. I *think* I had good signal with ICS before I did blat0id tweaks, but I am not certain of that. (ICS and the tweaks were within a few days)
My wife's Iphone still has excellent signal in those places. Tmobile Mytouch also has excellent signal in the same places. So something has changed on my amaze and not the cell towers.
What I have done so far -
1. went back to stock ICS by flashing the img file. That did not improve the signal. So then got back to energy
2. Tried another ROM - speedrom. No improvement in signal
3. Tried few apps like fresh network. They did not help
Please help me
What can/should I do? I love my amaze, but if I dont get consistent signal, I will have to replace it
Are there any tweaks that I can try?
How about the custom kernels that have been made for ICS recently, would those help?
Is there a way to increase the power to look for and catch on better signal? I can trade battery life for better signal
Thanks
I have same issue but with WiFi only. I never had GB I hope there is a work around

Found a workaround
This was dumb luck, but when I was trying to play around the app opensignal, it wanted me to set 2G for some of its functionality, since that functionality does not work over 3g. So I went to setup and set Network mode to "GSM Only" from "GSM/WCDMA Auto"
And walla! right after that my signal jumped from 1 bar to 4 bars and has stayed there. I went back to WCDMA and signal dropped, so now I change the network mode only when I need 4G. Its a pain, but at least, the signal is good when I need it.
So with that information, can someone help how I can tweak something to get my 4G and also good signal?
Thanks
try updating the radio if you have done so, even though you are going to have to go through the process of locking the device again and unlocking the bootloader again, that would be an idea to try, we still dont know what changes R2 radio update has done but its deff worth a shot

try updating the radio if you have done so, even though you are going to have to go through the process of locking the device again and unlocking the bootloader again, that would be an idea to try, we still dont know what changes R2 radio update has done but its deff worth a shot

I checked the version of my software and I think I already have R2
Build number
2.14.531.3_R2 CL373265 release-keys
So not sure if that would change anything
I have always had this problem as well sometimes I have 4 bars of signal then it drops to the X as in no signal,can't make calls or sends texts until it picks up again, happens totally random don't think it has to do anything with tmobile coverage since I live in the center of Miami. Also most of the time I have 2 bars of signal in most places, I believe it's faulty hardware

Krazex .. did you try to set your network mode and see if that helps your signal stick around longer and get better signal? That is working well for me.
I've tried setting my network to GSA and my data speed dropped to 2G.

yup, that's what this setting is supposed to do, but it increased the quality of my phone signal, that is what I am trying to make better/consistent. Because even after all the bells and whistles, calling someone/receiving the calls is the primary purpose of the phone for me and if that doesn't work, the phone doesn't work for me
GSM = 2G

Get a new SIM card.
My amaze won't get 4g in my house whatsoever, only switches to 2g when it feels like it.

A new sim card is a good idea.. so is removing the back cover and cleaning off the contacts with a q-tip and some rubbing alcohol. Taking something and SLIGHTLY bending out each of the gold contacts so they make better contact with the case, making sure there is no debris.
Another thing to look into- there is a TON of hacks for cellphone signal that can be done in build.prop.. playing with those settings is probably a good idea.
The last idea- the signal is actually NOT different. The number of bars it shows you is now just more ACCURATE. You still lose signal in ONLY the exact places you would have before.. but now when your phone would show you as having 1 or 2 bars(on gingerbread) right before you lose all signal, on ICS it shows you as having NO bars because you truly have almost lost the signal. It is VERY accurate, now that I am in an area with bad signal.. I have actually flashed gingerbread again and things did NOT get better, there was just fewer bars that weren't as accurate. But I lost signal in the same spots, and would lost 4g in the same exact spots..

Guys, OP here. This question/workaround is not about getting 4G. I am getting 4G just fine. Its about the phone signal (the bars). My amaze does not get good phone signal in some areas and when I set the network mode to GSM only (2G), phone signal strength and stability increases. and now I want to figure out how I can keep the setting to 4G and get a good phone signal

Hi SBD, thanks for coming in. I will look into build.prop (ro.ril properties I think) I will also clean any dust inside the phone, may be that will help. The sim card was new when I got my amaze .. but no harm in trying. So I will ask for a new sim card too.
However, in my case, I have a different experience. This is what I did in a weak signal spot.
Have 4G on. I get 0 signal. Can't make a call
go to 2G at the same spot, I get 2-3 bars. I can make a call
I used opensignal app to check signal strength in both cases. with 4G it showed 0. With 2G it showed 42%
Another test. On my route to drop kids off for their day camp, I was on a call (with 4G on) and dropped the call twice (bad reception areas) while going. I switched it to 2G and while coming back did not drop the call.
Before I found this workaround .. people called me and complained that it directly went to voicemail and I never got the call. (no signal). Since I found the workaround, I haven't heard that from anyone.
So I am convinced that there are some real issues in catching the signal with 4G on that get resolved in "2G only" mode. (may be it has to do with the kind of cell towers we have in our area and nothing to do with the phone)
will update if I find more

Yea, it should be lines that have ro.ril that youd eant to change.. and fortunately one of those that you can add(it isn't included by default) will do exactly what you need, default to 2g signal when 4g is too weak. I actually need the same thing, in Jacksonville we have great signal.. except in this new place I moved into. It drains my battery by trying to stay with 4g.. but I don't have time before work to find it.
Look for a tthread by "master&slave" titled something like "super build.prop tweaks" in the vibrant forums, I THINK they had that line.. otherwise google around for something like "build.prop signal tweak" as if it isisn't in that thread, there's a really good one on some other forum.
Also, I remember there being some app that requires root that allows you to toggle between GSM preferred and 2g only.. it changes it at system level, and I don't think it was on the play store, I think it was on Xda.
But yea, I understand your dilemma, and until we get an alternative radio to flash(which I don't forsee), that is the kind of workarounds you need. If you find a reasonable solution make sure to post as it will help me too!

I have had this problem ever since I got my phone in October (right after launch). Updating to ICS didn't help. i've been planning to root and try another ROM, but so far have been skittish as this is my only phone. hasoon, you say it's the SIM card? I am trying the switch to GSM only to see if it makes a difference. My problem is at home - I have terrible service and I live on a mountain with cell phone towers everywhere. My daughter's AT&T and my old AT&T Nokia E71x had excellent service there. I'll let you know if this helps. Maybe a trip to my local t-Mobile store is in order.
It's not the sim card. I noticed on google a lot of people have this problem with htc phones. It's just a bad radio.

Poor reception in India

I am using an AT&T Atrix 4G (rooted and has NottachTrix ROM with 37p radio) in India on BSNL AP circle and I have been getting really poor reception. It is so bad that I can only receive or make calls about 25% of the time. Many times, the phone shows no signal, but often it can't receive or make calls even when there are full bars on it at that moment. I tried using the other popular radio posted here, which is 36p and that showed no difference. Is there another radio that is better suited for this region and mobile operator?
I also have a severe battery life problem. With a brand new battery, it lasts about 24hs on standby, but even with a bit of usage it will not last full day. Sometimes it goes from around 60% to under 10% overnight (in 8hrs or so). I am using JuiceDefender for maximum battery life, and also verified with CPU Spy that the CPU is going into deep sleep as expected. Battery usage always shows "Phone Idle" and "Cell Standby" as the biggest battery consumers. Perhaps, the same problem that is causing bad reception is also causing the battery to go down quickly? I bought it as a used phone and used it on T-Mobile for a few days before leaving US. The battery life was terrible then too, but I thought it was because the battery was getting old, so purchased a new one before leaving.
Even though the reception on T-Mobile was also bad, it was nothing compared to what I am seeing here. Besides, T-Mobile didn't have a good coverage in that area anyway, so the reception was just like most of the other phones I tried there. My guess is that there is nothing wrong with the hardware itself, and the right modem firmware will fix both issues. Could someone who is already using this model in India, preferably with this mobile network comment?

Been using the Atrix for the past 6 months. Have used in AP Docomo, AP Vodafone and Chennai Aircel networks, Reception is top notch.
Everyone knows about the quality of BSNL signal and your problem lies there, IMHO.
Battery life is also awesome.
I used CM nightly and I do not overclock. I found faux kernel to be draining my battery so not using that too.

Interesting... I have heard people say bad things about BSNL signal, but I didn't think it would be this bad, so I was still under the impression that the issue is with the phone. May be I should borrow some dumb nokia phone from someone and confirm/rule out the issue with signal quality
I have't tried CM yet on this because I wanted the blur functionality for the dock, but I am not finding much use for the dock, so may be I will switch to CM one day, if only the support for biometric scanner is added. Thanks for the helpful reply!
Well, since the signal is always alternating, it increases the battery usage, i think
Well, my first concern is the reception. With full bars showing up, i am some times unable to make or receive calls. If his can still be BSNL issue, then I might just have to switch. When the phone is in this state, I have occasionally tried to see if restart would fix it, and though I can't confirm it 100%, I was almost always able to make a call immediately after the reboot. The reason I can't confirm that a reboot fixes he issue is because, there is obviously a few minutes of gap between that might have had external change as well.

Support for the fingerprint sensor is already present in Cyanogenmod 7. Give CM7 a try. The phone is smooth and rock solid.
And as ticiano_arraes suggested, poor reception or network quality has a direct impact on the battery, as the phone keeps trying to get hold of a stronger network.

Nice, I would love to give CM7 a try. Is I said earlier, I am less concerned about the battery life than the reception, as 3 out of the 4 times when I want to make a call, I don't get the signal immediately. Also, callers complain about not able to reach me. This is not my primarily line, so I am able to somehow manage so far, but if the problem is definitely on the network side, I will consider switching to a different service. In any case, I will try CM7 and report back.
What band are you using?2g or 3g?never set it to auto.Set it to GSM ONLY
I use atrix with bsnl 3g sim, cm9 Turk,radio is 100R don't have any signal issues or battery drain if I am using only calls I switch to 2g only otherwise 3g only mode use lot of data if I switch to auto or other radios I had lots of issues but with 100R no issues good signal as well as good data speed so pls try that using for nearly 9 months without issue
This is what I have right now:
- Select network - 2G Only
- Operator selection - Select automatically
I don't have a GSM Only option anywhere.
First try 100R radio I too call& battery issues then switched to this radio now don't have network issue when using 36& 37 radios most of the time my mobile was not reachable even when signal was showing do u use data? If not select 2g only using power Widgets u can easily switch 2g or 3g mode easily try 100R with nottachtrix it was good & if u r interested try Turk cm9 & 100R it gives better battery life than others comparatively

Regarding bsnl signal I have six phones in my home using bsnl I m in a poor signal area using 100R I have better signal than e71,n900 I'm using so try it with ur current from so u can check difference

Thank you, will give that a shot now. I found the 100R download link from here: http://forum.xda-developers.com/showpost.php?p=21525149&postcount=8
That post also mentions 30p, did you try that?
I got my mobile with .30 then switched to 36 got severe battery issues & switched to 37 it will show signal but mobile all be not reachable then switched to 100R never looked back try with ur current rom check difference.

If you have the stock ROM it's probably that the main problem is the radio that you are using right now. The radios control the way the antenna communicates and all that stuff. So if you are having bad reception, the antena is searching constantly and making more effort to keep you alive on the mobile network.
Try flashing a new radio, it's too easy. Just find in the forum a radio for your region( but it could be from anywhere, for example i'm in Finland right now but i use the normal att{usa}).
I read that you are using just 2G, that's great for improving battery life, but don't expect a huge amount. I always run in 2G and in HSPA+ when i really need the gps, fast info, etc, I'm always syncing with FB, Twitter, Instagram, listening to music and barely it last a day withe the extended battery(bh6x).
Hope this works for you
btw, ,flashing a new radio doesn't delete the data of your rom, it's so easy
I have now observed the signal quality over 24hrs with the 100R firmware and I think there is marked improvement in quality. There were times when I had no signal and I couldn't make calls, but at least I didn't have a situation when there were bars showing and yet the call didn't go through. Obviously, I need more time to see if what I am seeing is genuine.
On the other hand, I don't think the battery life increased significantly. With very light usage, it went down from 100% to 22% in about 23hrs and 70% of that is in Phone idle. I have attached 3 snapshots taken at different times of the battery usage to show what I mean. May be it is just the stock kernel not fully optimized, so I will give CM7 a try.
I installed cwm touch recovery 5.8.1.8 and wondering if the backup created by this recovery is complete enough for the stock rom so that I can switch back to it if CM7 doesn't work out.

Does this ROM also support biometric scanner? What would be the biggest reason not to use it and go with CM7 instead? Stability?

No, this ROM doesn't support biometric scanner and the stock Camcoder cannot record videos due to Nvidia Driver Issues (3rd party video recording apps work), apart from that sometimes random reboot, rest everything works like WiFi Hotspot, GPS is great, and instead of staying on GB I'd like to stay on JB with these few quirks...

[Q]Poor network as a hardware fault? Also memory card issue.

I have my I9300 few months so far and never had any issue with it. I'm with three network in UK and used many different custom ROMs and KERNELS, but usually stick with OMEGA and PHENOMENAL. Few weeks ago I've found that internet on my phone slow down. Also in my place, where I always had H+ good signal I have now only H. After couple of tests (speednet) it shows that I can go up to 10mbit/s so it was more less OK for H but normally I had between 12-15mbits. I was still able to catch H+ in different locations, but my speed with H+ dropped down to 500kbit/s (download) and with upload it was no connection at all (still had full bar H+).
I've changed ROM, KERNEL, MODEMS, went back to original, done 100s wipes and still the same. I've cleaned the phone, reset flash counter and sent to three to fix. I've just collected it from the shop and have a letter that they replaced some hardware and it's fix, but I'm not happy with it - in my place I can only connect to H, not H+ (my wife's S3, same network has H+ all the time). When I have H+ in some places, download speed is up to 2-3mbit/s and upload 2mbits, so still way to slow.
Does anyone experience any similar problem? Should I send it back to 3 for a fix?
The other issue I have is with my memory card and I've seen it around, so it's not only me. Had 2-3 cards so far and with JB it keep saying 'SD Card Removed Unexpectedly' or 'Preparing SD Card' or even 'SD Card Damaged' when wake up from deep sleep. This was second issue I asked for repair when I've sent my phone back to three for a fix. Guess what? It's still the same, happen again as soon as I've put my card back in. It's not the card fault, because I've already checked 3 cards with the same result.
So, I had two serious issues (I think) and few hours ago collected phone from the shop as a 'fixed' and problems still exist. What do you suggest, should I send it back for a fix? How to deal with them? Maybe it's only me and I should live with my issues?
For the signal issue, have you done a signal test with the carrier? Usually they have them on their website you can test the signal strength in your area. As well as are you city or rurally based? Because that can be an effect.
Maybe it is you from a freak or rare problem. If you can live with it depends on how much it would affect what you do. If you're by Wifi for the majority of your browsing or data using time it shouldn't be a problem, but if you're out and use it then maybe it might be an issue.
The problem is that I've always had great signal in most places around Liverpool incl the one I live now and my work. Now I have only 'H' speed and in some places, where I catch 'H+' ironically speed is worse. Other people with the same phone and the same network still have H+ in full speed.
I don't care when I'm at home, like you said, can always switch wifi on. Problem is when I go somewhere and want to use internet. It makes different, everything net related is slow.
I don't understand only how come they gave me my phone back with 'repaired' note, where the faults are still the same... Probably they just wiped everything, flash it with new official system (which was there anyway when I've sent them the phone) and sent it back to me.
i suggest you take it back to maintenance, may be a hardware issue.
Thanks, will do it and fingers crossed this time someone will fix it.. This will be second time with the same issue, with third one I should get new phone
