[Q] GALAXY S3 Signal problem ( Three network ) - Galaxy S III Q&A, Help & Troubleshooting

It seems my samsung galaxy s3 works only on HDSPA+,
when it switches from hdpsa+ to normal network it shows 2-3 BARS and Emergency Calls only...
This is happening since the first day I received the phone.
So basicly I do not have any reception inhouse, only outside ( and still depends.. )
The cell service is draining the battery life heavily and stats are ( 70% without service )
Also when I have no coverage and I try to select Three network manualy i get this message:

Does this sound like a defective phone that I should send back to Samsung ?

try tweeting ThreeUkSupport they can check the network in your area with your postcode

I'm in the centre of London so reception should be good...
Oh yeah forgot to mention, same microsim (if properly aligned) works great on HTC HD2
Was in three store, (the girl that works there) saw I have no reception even in their store. Told everything is okay in their side, send it to samsung..

Just got the phone back, it appears they just reset the firmware, STILL GOT THE SAME PROBLEM !!!
gotta send it again ...

There is definitely a signal issue with the S3 but Samsung is not admitting it because of (consequence) . I started using a S3 two weeks ago and now so regret with my decision. It will be great If every one post their problem in their Facebook,tweeter etc let the friends and public know about it, and this way should teach Samsung how to handle problem ....

I had the same sort of signal issues using a Vodafone sim. Tried 2 handsets but ended up returning both and getting a motorola razr maxx, which gives excellent signal and of course battery life

If you logon to the three website, does it show good network cover for your postcode? What modem are you using? Have you tried different modems? Is your apn correct?

Do you think? This thread was started on the 27th of last month and your the only person to report having a similar problem, lets not get carried away might just be a few defective units. If your phone is still faulty after you had the software reflashed demand a replacement, maybe the 3 shop will compare your phone to a demo phone in store to confirm yours isn't working as it should.
You may need to get your problem escalated to the ceo's office, you do this by emailing them. You can find their email & phone number on line. Good luck and keep us informed

I am also having this problem, so it's my wife. We've had three s3's between us and all have been the same. If you do a search you will find there are other threads with exactly the same problem we are having.
There is definitely a problem :-(

I had the same problem on Three inside the house (although it wasn't the phone as with the sim in my old S1 it was the same signal issue). The three support people have now supplied a home signal booster that uses my home broadband as a local cell tower and no more problems at home since.
The problem for me was that it's an old house with thick brick walls that block the 3G frequency band and since three have no 2G coverage you lose signal completely.

Try disable "fast dormancy".gorkhan made an app that's available on market. U need to be rooted to disable it. This will improve battery and signal if your carrier doesn't support fast dormancy. A lot say they do, but reality is they don't.
Try and see if it helps

ohk so i had the same problem ....
that time my cell was on auto mode gsm/cdma
so i changed it to gsn only and it got away !!! now i am having full signal hope this works..!!\
thats the 6th bug i found on my phone really dissapointed with it .!

Try to observe if it occurs again. My s3 had been set to "GSM only" since day 1 but, problem is still there. There is definitely a problem since my wife have another phone (Nokia) with the same operator as what's in my S3, mine got "emergency calls only" while hers is just fine. The most irritating part is that this does not occur all the time so, you can't recreate the problem and always caught me by surprise. You will just realize when people contacting you will complain later on.

Modem thread check other users with good reception on your network .
Flash same modem.
Their is a significant difference in modems for some.

I have just received mine today and it is the international version and I have the same problem. On GSM Only it works fine, but when I put it into WCDMA/ GSM Auto and it goes into WCDMA I cannot make calls, says not registered on the network. If I use WCDMA only I cannot make calls either.
Who needs a 3G phone that can be used in 2G mode only? And in 21st century?

Yup, there seems to be a network problem!
I just bought my S3 with Vodafone (Australia) and there does seem to be a problem with signal strength. Its almost non-existent in my house and I have to get out in order to talk on the phone. Quite bummed about it! Went to Vodafone, did a sim swap, did not help. Went to Samsung, they said they'll need to take it away for a couple of weeks for 'checks' (WTF?)
Another website says that Samsung apparently admits these problems and suggests to do a factory reset.

My problem was caused by a bad SIM.

My response from HTC about poor radio reception

I asked HTC if/when they were going to release the updated ROM for Europe with the improved radio ROM, this is the response I got:
We are very surprised to hear you are having problems with your device. I would first recommend performing a simwipe as this will do a soft-reset at the same time. This will clear any static from your Sim card. - Turn phone off - Take battery out - Remove Sim Card - Clean gold contacts on sim card (this will clear any static) - Replace sim card then battery - Turn phone back on You could try a soft-reset by pressing in the soft-reset button using your stylus. This will reboot your device much like a PC. This will normally cure any software problems and speed your device up. Please note that performing the below instructions will remove all of your data on your device. Please backup any data first. Another option would be to try a hard-reset to set it back to factory settings. In order to do this: - Backup your data first - Turn memory card encryption off - Start - Settings - System Tab - Clear Storage - Enter 1234 and press OK - Your device will now revert back to factory settings. Is it working now? Please let us know how you get on.

Very helpful I don't think. How will cleaning my SIM card possibly help?
LOL. Geniuses! According to the upcoming rate of new device models with very little changes and the repeatedly criticized support it seems like HTC is too blinded by the evolution mania that haunts all the companies suffering from the downside of economy - impayable rivalry.
As we are living in postmodernist times it is still important to remind the principle of the monster called modernism - FORM prior to ESSENCE.
Sounds like an automated response to me. Many people email companies regarding products and they really expect an expert reply but all they usually get is an automated response, based on the content of the email and maybe the email header.
It is a shame but honestly, if you want to ask a company something about a product, you usually need to have a contact in the upper hierarchy, otherwise you get what you get...an automated response and/or a non-qualified response.
Another thing is: what do you expect? There are only two possibilities regarding the poor signal reception of the HTC Diamond 2: HTC issues a new and improved radio firmware which corrects the problem OR if it is a hardware problem, don't expect much.
Some cell phone manufacturers are sometimes also very very clever (they think): they raise just the bar signal strength indicator without any real reception improvements.
It is usually a bad sign if the signal reception is crappy from the start, so don't expect much difference from a radio firmware update.
The only company I know of so far who actually improved radio reception was RIM with their BlackBerry Storm. I don't know how they did it, apparently the antenna design was OK and everything but maybe the energy saving setup kicked in too much at the beginning, who knows. Anyways: a firmware update improved things substantially and I've never seen a similar improvement on a device from another company out there.
Apple's iPhone 3G is maybe a good example: Apple raised the signal bar display but signal reception stayed the same, HSDPA connections were just a bit more stable but no real reception improvement. Good trick to fool customers.

I disagree, there are often significant performance differences between the Radio ROMs on these HTC devices. With my Kaiser I found an update resolved similar poor performance problems. I'm not asking for full on top quality reception but I would at least hope to get a basic phone signal in my house in the same places I could with my Kaiser. That's not too much to ask is it? Couldnt care less if I get 3G coverage at home (I have Wifi)

I can confirm the same for my old Cruise. Radio ROM's made great differences!
I'd love to know when this is coming out too...
My radio quality is very good in Holland with the stock radio. No need for an upgrade.
It is just generally poor for me. For instance now in my office where I would normally get full bars on my Kaiser, I have just two

So are there any other UK T-Mobile users with poor reception? Or with good reception? Or with ány reception?
It is not the T-Mobile network, in the locations where I get no signal in my TD2, the same SIM can get good reception in a Nokia
Reception
Mine is from Germany and i must say that my Elf had a higher number of reception bars than TD2 in some areas, but so far no reception problems. So maybe it's just the number of bars and not the actual reception, like many said before.
I can confirm it's not terribly sensitive. I previously had my t-mobile sim in a USB datastick, and the reception was better on my train journey to work. Now it drops connection a bit more frequently with the TD2, but it's not too bad.
I suspect the signal strength bars read lower than they should too. And, reception is erratic in that you get good recetion one day and poor the next, in the same location. This is hopefully firmware fixable.
One of the problems with the TD2 is the placement of the GSM/3G aerials at the bottom of the case, where you normally hold the phone. You have to make a conscious effort to hold it by the top for best signal. Except when you use Google maps with GPS. Then you hold it by the middle

He's not blaming T-Mobile for poor coverage, but rather seeing if the problem is worse on different networks, which may prove the phone radio is worse on certain frequency bands, or similar things which differ by network.
Also, same problem here on T-mobile (and 3) - Regularly dropping off the network at my house.
I'll add to this, coming off M40 at junction 3 call drops in 3g mode every time, fine in GSM. This hasn't happened on any phone i've owned since the awful NEC phones when 3 launched. It's definately the phone. I'm on Three BTW.

[Q] 4g issues (full bars constantly 4g rotating on and off)

Ok so i have an interesting problem verizon cant figure out so maybe someone else here has run into it. Im in an extended 4g network but it is here. I have full service -75 or better db and the 4g symbol just constantly switches on and off (and data does the same) I turned off 4g for now, and Im heading to NYC for work tomorrow night so i can test it there. It could be the towers here, could be my phone, could be the sim just wondering if anyone else has experienced this.

yeah my phone does this all the time. I had my phone switched out for an issue and both phones before rooting had 0 4G issues, and consistently did 20-30 down, and now do maybe 5-6 and 4G cuts in and out. I am assuming it is because of the PRL.
what PRL do you have? I have 15008. I was going to check our stock demo thunderbolt at work tomorrow and see what it has as it is still much faster than my phone has been after rooting.

Just went to VZW store with the idea to swap the phone. When i told them about 4G cutting in and out, they said, VZW is working on software update/patch, and it will be send out "soon". So, there is no need to exchange the phone, because before that update, i would have exactly the same problem with the new one. But, when it is going to be pushed out - that they cannot tell.......so, i decide to call Tech Support, and they told me the exact thing........the wait is the killer.....

same prl and mine did it rooted and non rooted. 15008 should be stock i think. Ill let yall know how it goes in NYC tomorrow night, if i have steady service the whole time it will point towards individual towers dropping signal.
You might need a new sim card, I had the same problem.

I have had the same problem with 4g and 3g being inconsistent and constantly swithing back and forth since the network issue last Thursday. It seems to be much better today for some reason that isn't clear to me. I have also noticed that my PRL goes between 1 and 15008 completely at random. My friend just got his t-bolt today and it came with a PRL of 15011 out of the box so I know there is at least one other PRL floating around that may help resolve these issues. All I can really confirm is that I feel your pain and aggravation. I'm going to keep a close eye on my data tomorrow since it magically seemed to work better late today and let you know if I figure anything out as to why mine suddenly seems better. I have to assume that Verizon is sorting out all these issues and is slowly rolling out tower updates but who knows at this point.
Also, I am completely stock and ripinning the stock radio config (no ##778# or other changes).

My rezound drops 3g at random moments.?

Hey folks,
I have been checking all over the web, and have not found enough useful info. My 3g signal drops out at random times when I know I have a good signal. I have put it in only cdma mode. Done all the other stuff, and it still does this. I live in a no 4G area, and never had problems like this with my incredible. I am afraid it is my phone, but I think it is the network. I haven't rooted yet because of this. Has anybody else had this problem? All responses are welcome. Thanks

Some people are saying that since our connection is verified with the sim card that it is a network problem caused by issues Verizon is having. Watch the web when people state they have 4G issues and you are probably going to see 3G outages at the same time.

This may help you. Whenever there is an outage this lets me get 3g at least

I should add that evdo is extremely slow at changing from 3g to 4g but if you're not in 4g coverage I had more reliable 3g using evdo.

Ugh, I'm battling with this issue as well. Rebooting doesn't get my 3g back. Is this a software issue? I'm rooted with a custom kernel/rom, but I had this issue stock.

This. I read in our forums that because LTE phones use a SIM card, they have to go through a type of verification process with the network to latch onto LTE signal. As a result, when this is happening the 3G signal bottoms out because the phone is trying to latch onto LTE. The same is true for going from LTE to EVDO as well.
Something along those lines, at least

Have you tried replacing the SIM? If at all possible try walking out of Verizon without them activating the new SIM. Seems when ever I'm at a Verizon store someone is always waiting to have a 4G device activated. I had one instance with a SIM swap that took 30 mins @ the store. Now I just ask for a SIM replacement and tell them that I would activate via phone support when I get home. In my past experience, activation happen a lot faster away from a Verizon store loaded with queued activation requests.

I've had this issue since the Vigor came out. In 3g, I'd lose data completely. Only a reboot or airplane mode would fix it. I had new Vigor sent to me and the same problem. I've been through several sim cards ( I switch between my Vigor and Nexus often). I've talked to VZW more times than I care to mention and they've had no answers for me. They even sent techs to my area to see if it was a network problem. No luck. Just have to live with it I guess. My nexus doesn't do it. Still prefer the Vigor though.

I had the same problem...3G dropping randomly thoughout last weekend. I thought it was my Rezound so I activated my Droid Razr. Same thing. I'm in Southern Oregon. I called the local Verizon corporate store and asked if there were 3G problems and they didn't know. I think they really are a bit brain dead anyway. I can say I've two of their top line phones phones and both losing 3G once or twice an hour was really pissing me off. I NEED data, I was ready to cancel my service (unlimited data) and go with Sprint but thought better of it as I'm getting 3G constant now. Maybe Verizon has worked this out, I sure hope so.
I run juicedefender, which kills data when screen is off. I wonder if this has to do with it? Doesn't happen often, 3g will come on without a reboot after a few minutes.

I really do not think Juicedefender is the problem. I have BatteryCalibration (need to be rooted) and never had a problem. I haven't read anything about Juicedefender being the issue. I think it's Verizon, in fact with 2 phones having the same dropping in and out of 3g I sure of it.
Also a few minutes is not even close to acceptable to wait for data. I need data constantly, if your using Google Nav and you lose data your toast, streaming music your toast and I can think of a ton other reasons 3g should never be lost.
Most of Sunday and today I have not had an issue...makes you wonder.
I was using juice defender. I was also having problems with dropping 3 and 4g. Try not running it. Since I stopped I haven't had any drops.

From my understanding, it connects thru evdo. The Resound tries to connect thru 4g first, struggles, forcing 3g off, and in the process drops data. I take no credit for this. Pwned posted the link I think. You would get a better understanding if you read the link on page one. Hope that helps......

[Q] Is there a fix for these 3G connectivity issues?

This is a difficult topic to search. anything with "3g, issues, connectivity, drop" brings up pretty much every thread possible lol.
I vaguely remember reading about people having problems with 3G not picking up/connecting a while back but havent heard much since.
It has been a constant issue with me as of late. I'll drop wifi when I leave work or my house and 3g picks up maybe....MAYBE 20% of the time(no exaggeration). ##data# to restore, updating profile, updating prl. Even tried a factory reset. No dice.
Sprint data isn't the best. That just may be the issue.

If you searched for an answer you would know that they are upgrading to lte so therefore lte phones wont work well until rollout is complete hence reason why older phones work better

Mine does the same thing. I have to reboot it about 3 times a day. It really stinks. The data will work after a reboot. It seems like the mobile connection gets stuck with switching from off to on.

Makes sense. If that is the case though. Arent S3 users out of luck too with this?
Don't think it's the chipset necessarily. It will happen to me when I'm at 4-5 bars , then just drops, and gets locked out. Normally if I flip the network on and off a few times it will turn back on, but sometimes a reboot is needed.
Maybe I'm wrong, but doesn't seem like it is the network or the chipset. No?

I have this problem sometimes when I turn off mobile data and turn on wifi at home then leave and turn off wifi and turn on mobile data but it won't turn on. Turning airplane mode on then off to reset the radios fixes it for me.
Thanks for the applicable replies everyone.
I just wasn't sure if I had missed a "fix" before I picked this up. The silence on the subject had me wondering. Guess we can only hope for an update/patch in the near future. Not a big issue but an annoyance.
Mine's been acting up the last 3 days or so. I used to run it all the time in LTE/CDMA mode. And that was fine for a month.
But being in one of the first LTE markets, that doesnt work anymore. It flashes turning on.. very quickly disconnected, then turning on.. over and over. If I put it in CDMA only, 3g pops right on and it's no problem.
One of my coworkers in another part of town is still on lte/cdma with no problems. I went to the sprint store to verify it was just them working on things and they said it was, and the employee had the same issue with her phone.
They said by all means, if it still doesnt work come the 15th bring it back in but at this point.. Just a waiting game i believe. Also, since my coworkers is still working that should mean I'm going to see LTE, and he probably won't right off the bat.
I also had connection issues when using the "LTE/CDMA" setting. Switched to "CDMA only" and it connects reliably, now.
As others have said, I imagine it's because it's trying to connect to towers that are being tested and can't. Switching to "CDMA only" prevents it from trying to connect to these towers.
Funny. It is backwards for me lol.

I've been having a ton of problems with this too. Constantly seems to be dropping even though I have full bars; does it on WiFi too. I'm switching over to CDMA only and will see if that helps me out. Hopefully we'll be seeing LTE here in St. Louis before to much longer.
i don't have any trouble with the wifi dropping out, but right on par with what everyone else is seeing on the 3g. except that the only way i can get mine to come back is to reboot.

This is exactly what happens to me. Wifi, no problems. 3g - reboot about 2-3 times a day to get it back. Mobile network just gets stuck on "turning on"
At least I know its other people now, so I don't try to return the phone and then get even more pissed when I get another one doing the same thing.

that's where i'm at. i've read elsewhere that the OG EVO had a similar/same issue when it first came out that was soon corrected by an update. buddy with a Bionic on VZW said he has a similar problem on it when he first got it, then an update fixed.
i'm new to HTC so i don't know how anxious to get for an OTA. samsung was absolutely horrible with my Transform. Got Froyo like 4 or 5 months after promised
in the meantime i might try this to disable smart-sync which actually links back to here. but that's how i came across it

Try turning off WiFi when it's not in use. It worked wonders for me.

Unreachable S6 edge in LTE/WCDMA/GSM (auto connect) mode

Hello.
I have bought a Samsung Galaxy S6 edge on the 17th of April. The default network mode is set to LTE/WCDMA/GSM (auto connect), it's perfect at most places, however at home (at a village) my phone is unreachable, I can use 4G/LTE for browsing the internet, I can send SMSes and call people (after a long time before calling), but my phone is unreachable. If I change the mode to GSM (without auto connect), it works perfectly.
As I said, my phone works perfectly at most places (for example at a bigger town), but doesn't work at home.
My phone has already been replaced by my carrier (T-mobile), but that's still not okay.
Any suggestions?
Edit: I have realised that the problem can be that I don't have enough signal strength when using LTE to use it for calls, but my phone still connects the LTE network when it's set to auto connect.
Go to the EE coverage map and check what you should be getting

i found there is a black spot in my back garden works in the rest of the house so work a look lol

My problem isn't that I don't have LTE at home, but that I can't use it for calls without changing the network mode manually.
Next stop ring supporr and ask if an issue, last week my call receiving was very intermittant and it turned out the 2 local towers were being upgraded for a better 4g signal

My last phone, a Samsung Galaxy S5 still works perfectly with LTE at the same places where the S6 edge doesn't.
Sorry beyond me may be some one else had some clues

The LTE on the Galaxy S6 Edge is weak and so is the wifi. I bought mine unlocked from Hong Kong. Tried 4G LTE in Hong Kong, China and Taiwan. All three places have 4G LTE issues and all three places have weak and slow wifi problems. Samsung tried to use their own Broadcom chip I take it...

The real problem is that the Edge isn't optimised for Chinese LTE... the same issue is happening with my S6 Edge in Australia.

I stay in Saudi Arabia and I am facing same problem. Same solution was turning to GSM only mode.
Is it a common problem ? 1 day old device and problem on its first day why ?

Hi seelrd ,
i'm from France , i bought the S6 egde gold version , my carrier is Orange the best network here in France
i have the same bad issue , i'm unreachable on all incoming calls , i catch 4G/4G+ and i only have 1 little poor bar network ,
i think i will send back my S6 edge to my carrier , for this price , everthing should work perfectly ,
as i can compare with my wife's iphone6 , same place , same house , same town , and she don't have any single bug ....
my question is , Can SAMSUNG bring a fix to clear this issue ?? or it is only a bad Carrier issue , and the Carrier need to fix this ??
Please need Help ^^
Its such a shame that this problem exists as it is a beatiful phone and the camera is stunning. Its just what I wanted.
What I didn't want however is sub par cell reception which after four days now I can confirm is a real issue. I started another thread where I've made come comparisons. read more here http://forum.xda-developers.com/galaxy-s6-edge/help/reports-dropped-calls-poor-reception-t3091992
Sadly this phone is going to have to go back. I'm hoping The LG G4 will fill the boots when its unveiled on Tuesday.
I have the same issue - based in the UK on Vodafone. This isn't a carrier issue as switching the same SIM into my old SGS4 gives a full signal when on LTE/WCDMA.
The only solution is to manually set to GSM only mode when on wifi for good signal strength and call quality.
And back to LTE when away from wifi when data speed is important at the expense of signal/call quality. I hope this can be fixed via OTA update.
that is sadly true. same thing happening in Saudi Arabia, unreachable when on auto mode while my LG G3 never had a single issue.
I hope that it is not a hardware-related issue
