Hey guys - my VZW Gnex (it's a refurb to replace my old one with a bad screen) has been having excessive network dropouts lately. When I boot the phone, it doesn't acquire signal for over a minute, when I place a call I lose signal afterwards, and data drops out randomly. The device will say it's connected (blue bars), although I cannot use the internet. Also, it'll randomly loose cellular connectivity, although indicate that it has signal. I'll go to send a text and it'll immediately have send errors, and I am unable to make or receive calls, even though it shows I have signal. To fix, a reboot is always necessary. This has happened on 4.3 (crDroid) and 4.2.2 (CM 10.1.3 stable). It has happened across all the different radios, 4.0.4 and up, and across several different kernels. Does anyone have suggestions, the phone isn't really usable if people can't get in touch and I'm unaware that they can't.
EDIT: When I go into the phone info menu *#*#4636*#*# when the radio has no data, it says preferred network is "unknown." If I change it, the setting immediately goes back to unknown.
U might need to go through the insurance and get another one.

This is a known issue with 4.3 ROMs. I'm not sure about 4.2.2. It looks like CM 10.2 may have a fix for it in the next nightly. One known fix is to edit build.prop to include
ro.telepohny.default_cdma_sub=0
Thank has worked for me.

I've been seeing this problem for a few weeks now, with several different ROMs, including the original rooted stock ROM now. In nearly all of my recent calls, I get disconnected one or more times with the message "Call disconnected" and a "Dismiss" button. I'm thinking that this is because of my EVO and not the other side, since usually if they accidentally hang up or something the call just ends without a message box. As far as I can tell, I have good reception (at least according to the bars), and this is happening at home, where I've not had the problem before.
Does anyone know what could be causing this? My wife's EVO is not rooted, and she does not seem to be having this problem. But then again, I've not had the problem until fairly recently either. I've tried updating my profile and PRL with each new ROM, but it doesn't seem to have made a difference. Anyone have any suggestions as to how to stop this from happening?
Go into the settings menu andbupdate both your PRL and your profile. That *should* help with reception related issues.

Unfortunately, I've tried both of those things. I just did some testing today, and it seems that my phone is unable to stay connected during a phone call for more than five minutes before disconnecting, even if I don't touch the phone and just leave it sitting on a table.
Any other ideas? As far as I know, I haven't ever flashed my radio away from its default (2.15.00.11.19), and I'm currently using the leaked stock gingerbread ROM (build number 4.12.651.1 CL41771 release-keys and kernel 2.6.35.10-gaa602b7 [email protected] #1).
Maybe it's time to unroot and contact Sprint?
You can try downgrading from 2.15.00.11.19 to 2.15.00.09.01. You can download it from http://www.mediafire.com/file/jyedjkp1bm5amwm/EVO_Radio_2.15.00.09.01.zip
Afterwards, go into recovery, wipe cache & dalvik cache then flash the zip. You will be taken to the radio update screen and appear to hang. don't worry or get impatient. After it is finished, you will reboot into recovery and see the words "clearing cache" at the top of the screen. Simply select reboot and then you will boot to your homescreen. The initial boot will take a tad longer since it will be rebuilding the dalvik.
Hmm... I'm hesitant to downgrade my radio because my wife has an EVO with the same radio version number and hers doesn't have this problem. Granted, she is not rooted...
I understand. I've downgraded and upgraded everything several times for testing purposes and troubleshooting purposes and have never had a problem. The only hing about flashing radios is patience and not to pull the battery. Anyway, you can always call Sprint and see if they can troubleshoot it for you from their end.

I would contact sprint @ 877-809-6696 (advanced tech supp). Ask them to push a full reprovision to your device. See if that helps any. I was having issues when when on the airave, I was unable to receive incoming calls. This corrected it. I did try all the other steps listed above without any success.
This is interesting. I unrooted to test things out before calling Sprint, and the problem went away. I was able to stay connected for an hour (where before I couldn't last longer than 10-15 minutes). Yay, fixed, right? So, I rooted again and didn't install any ROMs or anything, just rooted, and the problem came back.
So, I have a solution, but I don't like it very much because it means I need to stay unrooted. Anyone have any idea why simply rooting the phone with Unrevoked 3 (and doing nothing else) could cause calls to disconnect? I'd love to be able to root again, but I can't deal with a phone that randomly disconnects all the time.
I am interested in this as well as I am rooted using unrevoked and get disconnected as well. I do find that it mainly happens though talking to people who have service on AT&T.. Quite wierd. All I hear is a beep then disconnected. This happens when I first place a call and it rings once or twice then beep, disconnected...
This may not be related to rooting. I'm still communicating with Sprint about this issue, and along they way they replaced my phone entirely, and the problem is still happening. Very frustrating, but it makes it very clear that the problem actually has nothing to do with the hardware. I'm pretty sure there is some network configuration problem on their end now. I'm waiting to root my new phone until this issue has been resolved. It is killing me!

So whats the final call on this ..?
Is it Rooting , Is it network .. i am too getting psyche with this .
I'm pretty sure it is not rooting. But I don't yet know for certain what it is. Sprint thought there might be something wrong with the antenna on my phone, but they had already replaced the phone, so I think that is unlikely. They gave me a femtocell range extender to use in my house. Basically, I plug it into my broadband connection, and it is like having a mini cell tower in my house, giving me a very strong connection. Sure enough, when connected to that, I haven't had any calls drop. However, my phone still sometimes doesn't connect to the femtocell and instead connects to some other tower for some reason. My wife's phone doesn't do this, so I still think there is something wrong with my phone. I may contact Sprint again about this. ...sigh...
What is your area some area evo don't work properly like on rahim yar khan in this time connection don't work properly some signal drop and some time up i sure after few day signal work properly then problems will be solve.
My phone EVO is doing this now as well. Has anyone heard/read a solution?

I am having the same issue, out of the blue. No problems up until a few days ago. I'm wondering if it is maybe an issue with a certain version of the Evo. I have a version 002. Thoughts?
Greg_99 any progress on what might be causing this issue?
I know this post is long, but if you could give it a glance and let me know if you've seen a problem similar to this, and maybe how you solved it, it would really help me.
I've been experiencing what is very similar to the LoS problem that I've seen described elsewhere for a while now on my phone, but yesterday it morphed into something that makes my phone nearly unusable.
Some background: I'm using my phone on Cricket's network, using u2nl and autostart.sh to obtain 3g- if you don't know what those are that's OK, i'm pretty sure it's irrelevant to my problem.
LoS: To the best of my understanding, the common LoS is when you lose signal and you are unable to receive text messages or phone calls unless you restart your phone.
The problem: The problem I've been experiencing for some time is that the data connection will disappear, and sometimes I'll have to go into settings and disable/re-enable 3g to get it to come back.
The mutation: Yesterday my phone started losing 3g and replacing my signal bars with the circle with a line through it, then it would quickly regain signal and sometimes regain 3g, hit or miss. This sounds similar to the LoS problem, however I don't have to reboot my phone to fix it I just have to wait. Sometimes it will chain, meaning this will happen 4 or 5 times back to back. If I'm using a data program, like Navigation or Pandora, this will cause stutters or I will need to restart the program to re-establish a connection. Needless to say it's very annoying.
I did not make any major changes yesterday when this new problem began, but today I've been tweaking modems and ROM versions to try and fix it.
Specs:
Android Version 2.3.6
Baseband Version S: D710.10 S.EL29
Kernel Version 2.6.35.7-SPH-D710.EL29-CL852097
Build Number Calkulins.E4GT.ROM.v2.8.1
Hardware Version D710.10
Have you tried using qpst to reload all your phone settings and info. Just get your other phone info save it using qpst then load it up to your current phone
This issue seems to be all over the place, but I'm having extreme problems getting it fixed.
My GSM galaxy nexus regularly loses all signal everywhere I normally get full bars.
Also, sometimes I'll look at it WITH signal, and it enables Call forwarding and leaves that on until I go into the settings and try to disable it. (There is no option to disable it tho...it just automatically disables after it takes a minute to load call forwarding settings).
Has anyone else been having these problems and been able to fix it? I flashed new radios, roms, kernels....everything! And I just can't get the problem solved. Recently I flashed the UGLC1 radio and that worked for a couple days but now it's just as bad as it ever was.

if youre on stock just update to IMM76I thats the build just released to solve these issues
if your on a custom rom you may want to flash a kernel that has incorporated these fixes GLaDOS 1.30 for example
I don't really know to describe this problem better. I'm running CM10 (lately AOKP's latest build) with default kernels. I've flashed all the radios and tried a bunch of them in solid LTE coverage, I seem to have the same problem every time, which is the data seems to "stall."
It will show full signal, and then if i click a link, it will sort of just sit there, not really doing anything. Eventually it may load, or i give up in patience. Any one have any ideas?

I am using at&t stock rom and not yet rooted. Even I have the same problem. Tried to disable and enable data from the notification but did not help. But, when I turn on the wifi, and turn off the wifi again, it works fine. When wifi is turned on phone disables the data and try's to connect to wifi or shows the available networks, but I don't connect and I turn off the wifi, phone reconnects to the at&t data again and then it works fine. Not sure why.

I can't even run a speed test because it just sits there. Web pages "load" but wind up stalling. Sometimes they finish, sometimes they don't. I have no idea what's causing it. What modem are you on?

May be a good time to contact your cell phone provider for a replacement.
I was on a cross country road trip running CM9 on my GS3 and I kept running into the same thing. A temporary fix was to reboot the phone. Since I got back, I flashed SlimBean and I haven't seen the issue again.
In my case, I think its the SIM card. I used Google Maps/Navagation on my HTC G2 (using a micro SIM adapter) and my phone got HOT, I mean burn your fingers hot (upwards of 57 degC to 60 degC).
If it happens again I'm going to bring my SIM card back to ATT and have them replace it. I did some googleing and it seems like this is common with the Verizon variants of the GS3.

That's the next step... it means reflashing, and waiting for samsung to fix it though, which sucks a lot.
ive had this same problem and it would piss me off! i found out that busybox was the culprit. i uninstalled busybox and cleard my cache in recovery and all was well once again. if any of yall have busybox installed you may look into my solution.
I recently been having this issue also. But mine is a little bit different. Like my phone will say I am connected to "H" for data but when I load a Page it slightly lags switches to H+ and boom Internet works. When I stall for more then 5 minutes it switches back. I'm not sure if it's some battery conserving feature or what but I have no problem against at.

Hello,
I am running into an issue where I will lose connection after coming off wifi and it seems 4G/3G is not picking up. I must either reboot my phone or toggle airplane mode to regain signal. I've been searching around and I don't think I've found any thread similar...or it's hard for me to pin one down using search terms.
I'm running paranoid 2.16 and lean kernel. Gonna try and flash a radio and see if that helps...but if anybody can point me in the right direction or suggest a few things, I would greatly appreciate it.
Thanks in advance!
Lte or gsm version? Apparently the lte version has reception issues in general.
I used to take the subway to work. When coming out of the train, after losing service while underground, I would on rare occasion have no service while above ground in an area where coverage existed.
This bug existed on every Samsung smartphone I've ever owned (sch-r720 admire, t989 Hercules, and yes the i9250). I'm convinced it must be an android bug.

I'm stock (rooted)/GSM and I'm having this issue since 4.1.2. 4.1.1 was very stable for me. Today it lost it's connection completely to T-Mobile twice, where the status was always connecting even though I had 3 or 4 bars. Additionally, airplane mode would not engage (no symbol in menu) and could not be unselected from the power menu. Only way to fix it for me was to reboot the phone.
Additionally, I received a call today and the phone froze. I could interact with it barely, but couldn't switch apps or get out of the completely black phone screen. I had to unlock the phone to even see anything. After I missed the call, which rang for a long time (still no idea who it was - no logs and T-Mobile only lists connected calls), the screen would not come back on and I had to do a battery pull.
I'm about ready to just say F*** it and reinstall 4.1.1 stock back on this thing. I want my old phone back
Additional notes: The phone is encrypted due to my job requirements.
If restoring your backup cures the issues, then its baseband/radio/rom related. If not, the phone is damaged.
I had an sgs2 t989 which one day decided to lose its data connection. It constantly tried to sync and couldn't. Voice and text worked, but it couldn't get data (even edge). Changing roms didnt fix the issue and I had to exchange it in store.

I have this problem too sometimes.. CM10 M1, franco kernel. GSM nexus in Australia
I have a tasker task set up to cycle Airplane mode..
Freaking annoying.. always seems to happen when at the worst times..
I also had this behavior on my old i9020t nexus s to be honest..
