Strong 4G but weak LTE signal - AT&T Samsung Galaxy Note I717

Does anyone else experience this or know how to fix it?
I get weak LTE most of the time (2 bars)but when i do HSPA only for 4G, it gives me full bars. I also get network/modem freezing where i have to restart the data connection to get signal back.
Running stock gb and stock kernal, rooted with dag kernal and running cwm base recovery.

Yeah, I see the same thing. Manually turning data on/off seems to work for me.
-Edit-
What I mean, is that manually turning data on/off seems to reset to LTE. It's not an acceptable fix, I know, but it gets the job done for now.

yeah same here i'm on rogers and when i enable LTE i get 2 bars and as soon as i put gsm/hspa auto mode boom 5 bars. i called rogers and they told me to factory reset my phone, i did helped but a couple of weeks later same problem. i don't want to have to factory rest my phone every couple of weeks... they also told me if the problem persists to send it to repair. it's a brand new phone! and it seems like i'm not the only one witht his problem so. anyway the ics update should come out this month and hopefully it will get rid of this problem.

4g works but switching to 3g/1x doesn't seem to

Hello Just wanted to say thank you to all the peope who support this awesome website.
I got my TBolt yesterday and i know people have said they have had weird reception for 4g and what not. Luckily my house is in the center of a 4g area so in my house i have had perfect 4g coverage but today i went to town and i looked like it was trying to switch from 3g, 1x, or 4g but unsuccefully as it would only stay for a few seconds then disapear. Does this have to do with Verizon problems? if not what should i do?
Thanks
I was having the same issues going back to 3G from 4G. I would get no icons on the top of the screen and could only make phone calls. Tech support had me do a factory restore and that fixed it right away. Very annoying for sure to have to set up your phone all over again. If this keeps happening I'm not sure I will keep the phone. I am not about to factory reset every time this network handoff issue occurs.
Tech support told me they are working on a fix and I don't need to hard reset it yet. To me its silly to hard reset if its just going to happen again.
i was having similar issues and tech support had me take out the battery for a min and then put it back in and boot up and i had 3g back
Battery pull didn't work for me...
thanks guys battery pull seemed to work well!
Local VZW store said a national tech support email went out this afternoon regarding TB problems switching and dropping data. Email said the fix is on the network side and the phones have to be hard reset after 1PM mountain time to be fixed. Sounds fishy, but maybe worth a try.
I saw this linked in another thread. I take no credit for it.
http://forum.androidcentral.com/htc...blems-3g-data-dont-hard-reset-read-first.html
It helped me a little bit with my sporadic 3G connections here at work.
It appears vzw's eHPRD's network is down which is why data has been dropping once a tbolt is out of LTE coverage.
Use the ##778# menu (hit call after ##778#)-->password is 000000-->modem settings-->Rev A-->choose enable-->hit the menu button on the tbolt and commit changes
This is from the androidcentral forums. I can't post links yet, but a quick search over there will reveal the specifics.
This forces the device to use EVDO instead of eHPRD so you'll lose simultaneous voice/data, but at least if you're not in LTE coverage you'll get data. The device will still connect to LTE if it's available.
This worked on my device and my wife's.
I noticed that even in some areas of the same city that this network error is causing no access to 3g. I tested it by following the guide and sure enough the 1x switched to 3G. I hope Verizon gets this up and running. I think this is also causing calls to drop.

God Dam ****ing verizon biooootch, angered me so much saying i couldnt get on 3g because I voided my warranty by doing *#*#4636#*#* and shutting of LTE. OMG I wanted to punch her through the phone.
I've been having an issue and I don't know if it's related, but it sounds like it.
I've been turning my phone to "CDMA auto (PRL)" whenever I go out for the day to conserve battery. But there's this one place that seems to disconnect me whenever I go. It's happened twice now, but when I go there, I lose data service and can't manage to get it back even after switching to 4G. The first time it happened, it was out from about 11pm to 3am. Today, though, I switched it to 4G and it came back, along with 3G.
Now, the problem here is that my girlfriend's Thunderbolt is fine during all of this. I'll lose 3G, but hers will stay connected even though we'll be in the same location. I don't understand what would be different about mine than hers. :S
Hey DJComent try pinggolf12's fix it worked for me.

[Q] Mobile Data Drop - Not Suspect To Outage

In the past two weeks, my mobile data has been down. I don't believe it to be an outage in my area due to the duration of the problem, and the inconsistency with other Verizon Wireless phones. I was running Juice Defender for a while, and every now and then I would notice that the Mobile Network would drop. Toggling the Mobile Network would not fix the problem, either. I usually cleaned out my cached data for the Juice Defender app, turned the app off, then toggled airplane mode once. (Sometimes just toggling Airplane Mode wouldn't fix it, therefore I had to clear the cache for the app.) Now this fails to work. I cannot get my mobile network to connect by any conventional means. When I receive MMS messages, my network will connect long enough to download the attachment. Also when I do a search for a Software Update, it connects just long enough to tell me there aren't any updates for my phone. I've tried updating my PRL with *228 and I've even tried *18 from a post over at Droid Forums. Neither work. I've removed the battery and SIM Card as suggested in some other threads here at XDA. I've also removed the Juice Defender app.
The phone is not rooted and has never been rooted with the Temp Root methods. I'm not opposed to rooting, but if I root, I'm gonna perm root and I would rather not have to factory reset my phone if I don't have to right now. I'm mainly posting this because I cannot find anyone online with the same issue that I am having. Any help would be appreciated. Personally, I think its an issue with Dalvik-VM. I can attach a copy of my LogCat if needed. Any ideas on my issue? Thanks in advance!
Check your power settings, if you are in economy mode it will mess with your data connection.
I have a paid version of JuiceDefender, it has caused me so many problems I don't even bother to install it anymore.
~John
I also have the same issue, tried a couple basebands and could not fix it. I ended up not using it...
Every once in a while my mobile network or just lte somehow gets turned off and I have to turn it back on, but that's rare.
I tried juIce Defender and also had problems losing my connection so I uninstalled it. Plus the settings were so confusing to me. I'm using Green Power now and that seems fine.
You didn't mention mhs so I assume you're not using it but that has known connection issues.

Juice Defender gave me fits, too. I'm not using my phone as a Mobile Hotspot, either.
I kinda think its my ROM. I'll play around with some stuff, or I'll just get around to doing a factory reset and see if that fixes the problem. I'll post any solutions here for others.
Are you in a good 4g area? If you scroll down the general section here, you will find my topic. If you use 3g more than 4g, there is a post in that thread about##778#. It helped me. Sorry if it doesn't help you, Cheers.

I just wanted to let you know that I'm having this problem as well. I AM rooted and running CleanRom, but my daughter has a non rooted Bionic, and both of us suffered a complete loss of data today. My husband's rooted Rezound is fine.
I took my phone into Verizon today, and after initially just trying to swap out the phone (which I wouldn't allow them to do, it took me too long to get my phone the way I want it), they finally switched out the 4G sim card, and the data came back instantly.
When my daughter leaves school today, she will get her 4G card swapped out as well, and we'll see if it is in fact a network connectivity problem.
It seems to me that our 4G phones has a lot of trouble switching from wifi to 3G/4G service.

I will +1 this. My work WiFi is spotty, and so the phone falls in and out of WiFi. The Rezound HATES that and usually leaves me with no connectivity. There is definitely a WiFi->Mobile Network issue.
Try doing a factory reset. Could be a bad device... Im getting amazing reception on mine. I havent even seen my 3G or 1x icons yet. Constant 4G lock.
Forget what I said, my data connection has been dropped again for the past thirty minutes and there's no way for me to get it back.
I'm going to try a factory reset. I *really* don't want to have to send my phone back because my husband is getting amazing coverage on his Rezound. However, we're still in the first week of our Verizon contract, and if this looks like it will be a standing issue, then we'll have to cancel and go crawling back to horrible Sprint.

I think I'm going to try doing this. How painful was it for you to convince them to give you another SIM Card?
Edit: Just read your last post. Please let me know what a factory reset does for you.
They had no issues at all swapping out my 4G card, they certainly couldn't let me walk out of the store with no signal. They knew they had to try something.
The factory reset on the phone appeared to work. I've been steadily switching it from wifi to data, and the data signal picks up, albeit a tad bit slow. Only thing is, I still don't really get 4g, while my husband's Rezound has a great signal.
I got insurance on the phone, so I'll put up with it as long as I can before I start screaming at Verizon.
Good to hear. I'm going to try to switch out my SIM card today and see if that fixes it. I thought maybe it was something with the ROM, seeing as how my 3G will turn on whenever I need to send an MMS message, so a factory reset made sense to me. I just don't want to do it. Lol. Thanks for the info!
I've experienced it twice in the last 24hrs and it just happened to be right after I installed and used LTE OnOff. Don't know if there might be a connection there. I keep forgetting this phone has the ability to switch 4g/3G unlike the TBolt. Needless to say, that app is no longer on the phone.
KORM via the beast known as the Rezound.
I had an issue with the mobile network just dropping in and out (other people in the room did not lose signal). We currently don't have 4G and it is 3G only. I did a factory reset of the phone, but it continued to occur. Took the phone back to Verizon store to exchange it (it was 1 week old). At first they weren't going to and gave me a run around but in the end exchanged it. Have had no problems with new phone.
My girlfriend's Bionic keeps dropping 4G more frequently than my Rezound. I get this problem too though. Usually a toggle of Airplane Mode fixes it...but it's pretty damn annoying. Happens once or twice a day!
A Factory Reset fixed it. Everything went smoothly, too. I backed up all my SMS Messages with HTC's Messaging app, and got my network back as soon as I restored it and set everything back up. Hopefully this will help anyone else who might have had the same problem.
I've been side by side with a fresh Rezound and watched both of them jump from 4g to 1x to 3g and sometimes never 3g. The problems were a million times worse with my droid charge as it's a combination of the handsets and the towers.

Hmmm
I have this happen if I am in an area with NO signal (such as the basement level of my office building) for long time. Only a reboot will bring back data. Does not happen often (maybe 2ce in a month and a half).
I am intrigued by the person who blames the install of LTEOnOff. I have it installed but do not use it. Maybe if I ever have to hard reset (such as if ever run the unlock), I will not reinstall that program.

[Q] 3g and 4g gone, only 1x

I havent done anything to my phone lately and besides just having roms on it...so i my 3g and 4g data is now gone and i get 1x signal. The signal alternates from 1x to no signal at all. This http://forum.xda-developers.com/showthread.php?t=1457659 is what i got on my phone right now and i got the radios installed and i still get 1x. At one point 3g showed up, but its really slow. So my question is, how can i fix this network problem?
ps. i have been struggling with this for 2 weeks and ive decided to try and fix it, but no luck
edit: ive taken the battery out and luck either, i also found a thread on how to fix the problem but it didnt help
i too have had this problem for 5 days now. i have been thinking of flashing the phone again to see if it would fix it.
Well i got some signal now, i went ahead and just added another ROM. I get signal every now and then, but i think i would have been better off with just constant 1x signal, instead of having no signal at all then some 3g coverage (really slow for some reason).
I just rooted my girlfriend's Thunderbolt last night and I'm having this same issue.
I had to roll back her latest OTA update and go back to 2.11.605.0 and then run Revolutionary. Since I rolled back her software, though, I've had the 1x signal issue. I assumed that installing the new ROM would fix this (BAMF Forever 1.10).
I've installed BAMF after using Superwipe, and everything runs smoothly. It's a great ROM. However, I can't get anything above 1x signal.
I've done the trick using ##778 and changing the Rev. A setting...no dice (and from what I've read, this is better in areas with no 4G. I live in Brooklyn, so I definitely want the 4G LTE).
I've tried the MR4 radio released just a few days ago, the radio from 2.11.605.9 OTA, and the MR3 radio. Same problem. I guess I'm going to try out the remaining radios I haven't touched, but I honestly don't think that will do anything.
Does anyone have any suggestions??

Ok I take this all back, she tells me her phone now reads 4g lte with full service. Looks like jumping across a few cell towers did the trick.

[Q] 4G connection but no data

For the past 4 days or so my phone has been able to "connect" to the 4G network but I cannot receive data over it. However when I switch the phone to 3G only data works flawlessly. Calls and SMS works fine but the browser and any apps that use data say no connection. The connection icon is grey instead of blue.
I've been running CM7.1 on the thunderbolt just fine for months but I decided to use another ROM just to be sure. Put thundershed 1.6 on today and for a while 4G worked but it died again. was using radios 1.48.00.0906w_1, 0.01.78.0906w_1. Thought it may be a problem with those so I flashed the just-released 1.49.00.0406w_1, 0.01.79.0331w_1. No change.
I've gone through all the other troubleshooting steps too, hard/soft reset, battery pull. reseat SIM card, toggle airplane mode, switch off the LTE radio, etc. Called verizon and they confirmed I have a recent PRL.
Anybody have thoughts as to how I can fix this?
i've been getting in and out data connection with the newest radio on my thunderbolt atm...i'm starting to wonder if its the phone itself
I don't think its anything we can fix ourselves. So many people are having problems similar to this that it must be verizon. I had exactly the same problem you are talking about and I can get it to straighten out by turning airplane mode and taking it back out.

I really hope it is verizon and not my phone, but I've talked to them probably 3 times in the past 2 days and no one has even hinted that they are having network problems.
So right now I guess I just have to wait it out. Man I hate streaming music over 3g...

Update on the situation - My 4G data is back after about a week.
Looks like I was temp banned from Verizons 4G for using too much of my unlimited plan. Can anyone confirm this happening to other people?
Thats what I suspect at least, it could be a coincidence and their 4G tower in my area was broken for almost exactly a week.

Weird 4G LTE problems

So my HTC EVO 4G LTE has been treating me very nicely.. great battery life and CM10 is smooth as ever.. the kernel I have is great and I get a 2.0 GHz overclock without problems. The weirdest issue has been haunting me lately. On CyanogenMod 10, I am unable to use the 4G LTE service that is located on a tower about 150 feet away from me at this moment. The issue is that while the phone connects to the service and I can call and text, for some reason data never works. I get 4 bars that I could only get from this tower, and looking in the phone information section of *#*#4636#*#*, I see that the tower shows up as LTE. Now it used to be that on Sense, I could turn on airplane mode, wait about a minute, and then connect to 4G LTE.. but now not even airplane mode can get me connected to it. There should be no reason that the phone can't connect to the tower because the signal, when connected, is very very strong. Does anyone know of any potential fixes for this issue? It's been haunting me that I'm located here in Dallas with a 4G LTE phone on Sprint next to a known working 4G LTE tower and people around me with Samsung Galaxy S3s and other 4G LTE phones are connected but I can't. Thanks for your help in advance.
By the way, I did search the forums and surprisingly no one has an issue similar to this in any of the topics that I checked.
Bump.

I installed the new radio from the OTA onto my phone and I thought it'd fix the problems but the problem was only temporarily fixed when I reflashed CM10. 4G LTE worked for a few hours.. but then after I went into a building, the signal dropped to 1 bar, turned on 3g, and call quality became utter crap.
I would post in deck's thread but I'm not sure the issue is specific to CM10.. I used a sense rom and for the first few hours of use it worked great and I would get strong LTE signal.. but after that I seemed to again be able to connect to the tower that's transmitting 4G LTE and in the network settings it would show up as LTE, but no data connection could be established.

May sound simple, but did u do a full wipe between roms? Factory reset? I know after going s-off I had to call sprint so they could send me an update to fix data and calls.

Yes, I did full wipes between roms including factory reset and system wipes. Only my SD cards are left unwiped.
I called sprint support today inquiring about that but the guy just had me go into ##72786# and reset my network connection settings.. didn't help the problem.. Any name to that update that I can ask them for that'll help me get it?

They should have recognized it if it was an error. So calling sprint won't do much. There's an app called network in google play store. Has the option to switch to different bands, or a lot more than any stock program will let u switch to.
Try switching from CDMA auto to Evdo/LTE or the other LTE options and roaming bands they have on there and see if it helps. Hopefully someone with a fix will see this thread soon enough. Only other thing I can think of is the ##4636# (digits may be wrong)and switch some settings in there.

Nothing of the sort fixes the issue.. I'm gonna try reflashing radios.
I'm on 1.15, S-On, HTCDev unlocked, CM10.I have the same issues.
When i reflash the kernel, LTE will work for several hours, and then I get the gray bars of doom. Oddly, I still get a data connection with some apps (Reddit Is Fun, etc.), even though the phone shows no data. It's been so frustrating that I've considered going back to sense...

Yeah that's exactly what happens to me.. and no matter my attempts to airplane mode the phone refuses to connect to 4G LTE data after a few days of reflashing.. So odd.
Just clean flashed deck's most recent build from IRC (9/19?) and I'm having the same problem as before. This time it didn't even make it an hour before LTE went away.
And after searching around, apparently we're the only people in the entire world experiencing this issue.

I.E. His statement still stands because we would still be the only people in the world having this problem..
I am honestly stumped as to how to fix this.. Sprint support can't help and I sat in the irc and people would tell me to force lte mode in network settings.. Doesn't work.. Because even though I get data connection.. I then lose the ability to call and text.
I tried paranoid, cm10, and aokp. I couldn't get lte on any of them. And phone calls were at max volume, distorting the speaker even, no matter where the actual volume indicator is.
Went back to a sense based rom and no problems.
1.12 panda hboot, s-off'd, with the new firmware.

I am having the exact same issue as you with the "Greg bars of death". I had good consistent 4g at one point in early September (possible unofficial 9/6 build based on saved speed tests) but not since then. I have also found that having LTE off gives me more reliable 3G data.

Join the club... it's the typical LTE connection issue with the EVO LTE. Its not your phone or updates. Even a 100% stock EVO LTE with all the updates has this issue.
