Losing signal after text message

This happened two times, once where I had full five bars with a HSPA connection and at home more often where I have two bars with an edge connection.
What happens is, when I get a text message, I will view it and then once I reply, the signal will drop and I won't have any signal, and have to wait for the phone to reconnect.
The same has happened outside with full service.
At home, I have wifi calling enabled and sometimes that will even drop and I will have to wait for wifi calling to reconnect or for the phone to gain back reception.
Is this a common issue? I have the ota radio on it, (not flashing any other radios, due to the fear of bricking), and running on Cyanogens 6.1.1.
Edit: This tends to happen a lot, when I get multiple messages and reply to each other quicky. I do about 6k messages a month and its getting annoying having the phone lose/drop signal when replying or receiving messages.

Does this happen when you use the keyboard or the phone in landscape? I found out that if you cover the top party of the phone just above the camera with your hand the wifi completely drops. Turns out its the same antennagate as iphones but only affecting wif (so far). I actually can't use my keyboard on wifi because right away after putting my left hand on the top of the phone to hold it in landscape my wifi drops from full to either 1 bar or completely turns off and switches to H or 3G. If you're having the same issue then post back.

Yes, I actually do have the same problem. I don´t think there is a solution for it is there?

I'm seeing the same problem withnmy g2, running cm 6.1.1. I have a case on my phone as well.

i am having this problem when i turn the internet on. Happens instantly.

I was having a similar problem, running cm 6.1.1. I flashed pershoot's kernel and have had better reliability during my two days or so of testing.

I've had 'similar' issues. Its rare that my signal drops completely but when I have the phone open in landscape mode and am sending a text using the hardware keyboard, my signal does seem to drop by 10-15db.
I had the same issue with the stock ROM as well.
Although this is not a solution, I have noticed that the signal isn't affected as much if you keep your hands on the back of the phone 'low', as in my index fingers sit below the camera on the back of the phone when texting...

I've had connection problems ever since I updated the radio. My signal before that was great, and so it was at home. Ever since the update, I go from 2 bars of HSPA to Edge, which is pretty frustrating.
At work, my signal was great and never drops. But today I've been going from GSPA to Edge to 3G over and over, which has me really annoyed.
Edit: Also, I tend to lose connection when I receive an MMS, not a regular text. When I get a call and I don't answer, I lose signal completely, which has caused me to miss voice mails.

[Issue] Complete loss of signal when not in use for an extended period of time

I was using an iPhone 3G on the Fido network and switched to Bell on Thursday to get the Galaxy Nexus. This is my first Android phone, already own a Xoom.
Since buying the phone I have noticed a reoccurring issue with my signal. I leave my phone next to me when I go to bed and when I wake up I notice that I have zero bars and when I try to make an outgoing call the phone says I am in airplane mode (but I am not). Also none of my apps say they have data and my e-mail hasn't been updating.
I haven't figured out the best way to get a signal working again, but so far it appears to regain signal when I start using it for a few min or if I restart the phone.
While I am awake the phone sits next to me with full bars only 5 feet from where it rests overnight.
Anyone else encounter this issue? Is Android trying to save battery by weakening my signal and therefore cutting it off entirely? Possible defective device? Issue with Bell's signal although I seem to have full bars otherwise?
thx guys

I have the same issue. Flashed different radios and roms but still the same thing.
I've read similar issues with other people on Bell Canada.
Wonder if it's a problem with Bell.

Same Here
just finally noticed this here too in NYC on T-Mobile phone bought unlocked from UK. I remember having similar problem with my nexus one thou it was eventually fixed but as it was then now I can fix it with a restart.

Well with this only being released on Bell/Virgin in Canada it is hard to tell if the issue is network or device related

This is usually a SIM issue. Try someone else's to test, or just ask your Carrier for a new one.
In the meantime you can toggle Airplane Mode to bring your signal back.

Here are some example screenshots. In these cases my signal drops & returns very quickly without me doing anything.

I gotta run some more tests on my phone after an extended period of inactivity, but trying airplane mode last time freaked it out. It already thought it was in airplane mode when I tried to make a call. I had no signal, it said please turn off airplane mode, went to the setting, it was off, so I turned it on. I then tried turning it off, but while the check box responded the airplane logo would not go away in the statusbar. I had to reboot the device.

Hey Guys,
same problem here in germany. Signal drops when i leave the phone alone. But not every time. Over night the signal stays all the time.
sometimes even a reboot does not solve the problem... it drives me insane!

I'm also on Bell and on my second GNex. The first one had that issue as well, along with horizontal streaking on the screen so I returned it. I'll keep you posted if this handset also drops signal.

As a heads up to this topic, there is a similar issue with Airplane mode turning itself on. The low signal/no signal issue and airplane mode might be related. The thread is here: http://forum.xda-developers.com/showthread.php?t=1387943. There is also an "issue" opened with Google about it.
To throw in my two cents, I've also noticed this issue occuring infrequently in nyc with tmo. Usually during the day at work the signal will drop down even though the phone hasn't moved. Usually it comes back but I have had fairly longer delays going from no signal areas to signal areas, sometimes 60-120 secs before the device recognizes the signal. I'm wondering if this is a result of the device polling for signal less often to conserve battery power.
Keep the information coming! This is how we work out the real bugs!

this is driving me insane. I want to throw my GN right against the next wall. Signal drops and does not come back. I have to switch to 2G to regain my connectivity.
flight mode doesn't help, reboot doesn't help, switching all data off doesn't work.
What the f* is going on here? is it a provider based problem? or is it due to a conflict with ICS or anything? if it lasts i'll switch back to my good old desire ...
forgot to say: switched radio today, doesnt bring any improvement. Tried the xxkk6 and the newest UGKK7. Back to xxkk6 now.

UGKK7 isn't the newest. UGKL1 is.

Ive had the same exact issues as well. Have had a thread open for quite some time too.
http://forum.xda-developers.com/showthread.php?t=1365389
I tried UGKL1 last night and finally thought I had it working but still doing it.

I flashed Modaco lr6 this morning and haven't seen the issue since.
Before the flash, it would lose signal everytime it went to sleep

Is anyone here still having issues with the Galaxy going into Airplane mode after the phone is left in idle mode for hours? If my phone is left idle for a long time it goes into airphone mode and I have to restart the device to be able to make and receive calls. It's strange because I transferred my T-Mo account onto a new SIM card when I purchased my GNex.
I seriously hope this isn't a hardware related issue because I would be without a phone again...

This thread is a better resource to go to for the airplane issue:

My issue was also connection drops. I since replaced my SIM card & Nexus. No more frequent connection issues. I can confirm that I still get the airplane issue, but because I am not losing my connection frequently, the airplane issue only happened once since mid December.

I'm seeing weirdness as well - when I come out from under the subway, I can't get back a signal. Going to have to revert to stock (uuuuugggggggggh) and see if it persists.

I have the same issue and it happens nearly every night. I wake up in the morning with no signal and once I reboot I receive all of my messages etc. I am not sure if it started happening since I rooted and flashed Revolution HD but either way it is extremely irritating.

I have had this problem since I got my phone mid December. Over the past week it has become worse. I was anxiously awaiting the 4.0.2 upgrade.
I just upgraded to 4.0.2 yesterday, but unfortunately my signal dropped a few minutes ago. Grrrrrr, I had hoped that 4.0.2 would solve the issue, but apparently it doesn't. Maybe 4.0.3 will do the trick, but I don't expect this to be released very soon as they are rolling out 4.0.2 just now.

Analysing WIFI issue

Hi
My WIFI seems to have gone wonky. It appears I have the 'loose antenna' issue, but have been running some other tests.
Tests were done at 2 and 5 meters from WIFI AP.
1. Run WIFI Analyzer.
2. Cup hand over the top of the phone (no squeezing, just gentle cupping, barely touching the phone).
3. Looses about 20db
4. Remove hand
5. Gains lost 20db again.
Occasionally, WIFI, just drops (and gets turned off) and get's re-enabled.
I do NOT have the 'Switch WIFI off' option ticked.
Can anyone confirm the same behavior on a perfectly working phone (and possibly one that has the WIFI issue if not fixed already).
Thanks, very much appreciated.

I've had one with the hardware wifi problem and now have one which is fine - even with the ok one, covering to top right hand corner with your hand will indeed cause the signal to drop as you describe.

Bah, this is just HTC's version of the Apple iPhone mess up they made when they completely lost signal.
Surely they should test for things like this before release?
WiFi maybe not so much, but apple and the Signal!!

I believe these are two seperate issues. I get the 'random drop' issue too, which is a real annoyance. Essentially most of the time when I try to browse I have to wait for my Wifi to 'drop', and reconnect, before I can do anything - it takes a good minute or so to do, and happens quite frequently

My poor signal issue seems to have started in the last few days. It used to be good. Where I am sitting now (about 5 meter from AP, via 2 windows), 4/5 bars I used to get, now only 1/2 bars and many more drops than I used to get.

Wifi Problems!

Hey there, I brought my htc one x on contract with 3 at the start of august, the first one had a problem with the battery and had to wait to have a new one in white but eventually, I recieved one that worked. It had been great till a few weeks ago where my wi-fi has been poorer than before, everything else was fine though including my computer and few other things but my one x suddenly buffers every youtube video which take a while to load and keep pausing, the wifi disconnects every now and then but the internet along with twitter and facebook you can't always tell but it defiantly is poor at times. The Wi-fi icon at the top is full at times even when it isn't connecting well to the wifi and then always goes up and down. Always random. I tried the squeeze test which has once or twice improved it but nothing is effected by it usually, even when i downloaded the wifi analyser app, at first i squeezed it and it shot up but since then even if it says the signal is good, it still isn't. It's the youtube that is the worse, but I don't think it is just that as the wifi disconnects and goes up and down at times and just poor compared to before. Do i have this same problem though? The squeeze dosen't always work and what shall i do? Go back to the 3 store?
Really was a good phone till this problem popped up.

[Q] Intermittent WiFi Issues on 8.4 T700, Is This Common?

I've heard about nebulous "WiFi problems" but it doesn't seem like there's any authoritative information on what those problems are. In any case, I was wondering if anyone has experienced this:
This is easier to notice while using some kind of streaming service like YouTube, Netflix, or Hulu, but it's not tied to any specific app. While using the tablet for internet-related activity, every once in a while, the WiFi just stops working. The icon shows full WiFi signal bars, and it's still connected, but any and all attempts to use the wireless connection utterly fail. However, turning WiFi off, then back on, immediately fixes the problem. This happens randomly, as in, sometimes it will happen after 5-10 minutes of use, and other times, it won't happen for several hours.
The tablet is relatively new, has never been dropped or otherwise abused, and has the fitted OEM wraparound case on it. I'm at a loss to figure this out, and am close to just sending it back for a replacement. But I wanted to make sure this wasn't a semi-recognized problem before I did so. Especially since this feels like a software/kernel problem that could theoretically be fixed by installing a different ROM.
Thanks in advance!
