[Q] Fluctuating Phone Signal?

Ever since I have bought this phone, I leave it in a place overnight where I get 4-5 bars of signal (right next to the window). However whenever I look at the detailed battery usage, I notice that the signal reception on the phone wildly fluctuated during the night..... See attached screenshot...Is this normal? Is there a reason why the signal so fluctuates. I would have thought that the signal should be more or less stable in the same position.
Just wondering if someone could shed some light on why this is happening....

4.0.3 has an unofficial change log... they mentioned a signal fix and battery statistics fix. this may solve your problem, so when the time comes go ahead and take the OTA update. If you cant wait you can always flash it through CWM

Which ROM/Radio are you using?
I had the same issue you are describing when I run any of the AOSP based ROMS, I switched to ARHD and then stock rooted 4.0.2 and the problem went away. I'm on the same network and in the same city as you, so this might fix it.
R

I too seem to be having this issue but I only noticed it today and I have been running the FoxHound v0.9 4.0.3 ROM for a few days now (see my signature for full details) and my issue SEEMS to be related to when I place the phone into sleep mode / turn of the screen.
When I am using the device its ok as long as I am USING the device but as soon as I turn off the screen for any length of time and then turn it back on I get the blank signal icon with no service and then it connects and it does this over and over and over...
My baseband is UGKL1 which is standard for my region (Canada) so with this being said, does it seem that I am also suffering from this "4.0.3 bug"? Could it actually have something to do with my lockscreen / turning off the screen?
Please advise...

it could be related, best bet is to do a nandroid backup, install a 4.0.2 rom and see if the signal issue is resolved. If it isn't you can restore your backup. If it is you can join me and others in waiting for an OTA that fixes the issue.
Cheers

Hmmmm... I see that you are STOCK/ROOTED and I assume that in the UK the latest STOCK ROM is 4.0.2... Is that correct?
I do have a nandroid backup of my STOCK ROM that I could flash back to but it is 4.0.1 as we here in Canada have NOT yet received any updates.
With that being said... Are there any CUSTOM ROMS that are 4.0.2 that I could try that you are aware of or what would you recommend?

Hmmmm... Well it will suck to have to wipe my device again but if it will fix this issue then I guess it may be worth it. I will make a nandroid backup as well just in case.
Are there any themes available for this ROM that you know of?

Guys
I was on stock 4.0.2 with the XXKK6 baseband. However I have been trying to flash a few new radios to see if they matter. I have now settled on the XXKL1 and I can say that it beats all the previous ones, esp. in my case.
I say that as I used to leave my phone overnight and see at least a 1%/hour or more of usage as most of you see normally. Also another thing was the volatility of the radio signal which with the phone being in the same place overnight seemed really odd. However since I have updated the XXKL1 radio, I get a more even usage and the battery usage has gone down noticeably overnight.

GSM - GNEX Signal Drop Solution - Working ROM,Radio,Kernel combos. POST HERE...

***EDIT*** I believe that I have found the solution to this issue (at least for me) by flashing the FuGuMod Kernel as advised to do by 2 users (jetrii and slyydrr) who advised me of this in the following thread here http://forum.xda-developers.com/showthread.php?t=1487056 on pages 7 and 8 respectively.
This fix may NOT work for you but I can say that it has worked for me. Please see post #33 (and onward) in this thread.
I have painstakingly been trying to find a solution to this issue and it SEEMS as if I have FINALLY found one so if I have helped you in any way then I ask that you please press the "Thanks" button and please visit the thread above and say thanks to jetrii and slyydrr as well. I also recommend that if this works for you that you go to the FuGuMod thread here http://forum.xda-developers.com/showthread.php?t=1438417 and pay tribute to nikademus for his kernel!!! I know I sure have... Also... Make SURE that you flash the correct kernel version for your ROM ie: 4.0.3 ROM = 4.0.3 Kernel, etc...
Thanks...
Hi everyone,
I have decided to start a fresh thread here as I have seen (and replied to) many threads regarding people with the GSM version of the GNEX (like I have) that are suffering from random signal loss of both data and GSM services for apparently NO REASON.
If you are also experiencing these issues I ask that you please post them here so that they are easy to follow and I also ask for anyone with ANY answsers to please post them here as well. Also... Please post what firmware you are running and any steps you have tried to fix this issue be them a failure or a success. I have done the following...
I am currently on the FoxHound v1.0 AOSP 4.0.3 firmware and experience these random signal drops. I have flashed NUMEROUS radios / modems to try and fix this with no success. I had been told by someone that the issue MAY be a BUG in the 4.0.3 AOSP ROMS but I have a hard time believing this as some people do NOT experience these same issues while on 4.0.3 ROMS.
What did work was to flash to the Android Revolution 4.0.2 ROM and on this I do NOT experience these random drops which COULD mean that the problem DOES lie in the AOSP builds of 4.0.3 but again... I have a difficult time believing this but it could be true. Also... Stock firmware (4.0.1) for me here in Canada does not experience these random signal losses either.
This is very annoying as I want to run the 4.0.3 custom ROMS for their customization capabilities, etc but I cannot keep my device in a USABLE state when on 4.0.3 so I have to go back to my trusty SGSII.
Again, please post here to voice your concerns and opinions on this and perhaps SOMEONE will be able to find us a solution.
Thanks,

are you using your carrier supplied radio?

Yup. Im on UGKL1 which is the radio that shipped on my device. I have also tried other radios (XXKL1, UGKK7, XXKG6, etc) as I mentioned as well and I still experience the same issue and others have mentioned the same things as well with no successes.

There was this one time that I had lost signal randomly (while on stock unmodified out of the box ICS) but I was able to get it back with a factory reset. After that it never happened to me again.

Thanks for the comment. May I ask what Radio your device has on it? Are you running any sort of custom ROM now? If so, what are you running?

Right now the radio is KK6 (im on stock yakju 4.0.2 now) but at the time it was what came with the phone (shipped from Rogers)

Hmmmm... Interesting... You got an OTA update to 4.0.2? I have seen other posts that people here in Canada are complaining that they have not received ANY OTA updates at all... When did you get this?
Since I have been on a custom ROM I have not seen this update obviously...

I'm on GSM with Rogers as well. I haven't noticed any significant signal drops with the exception of my basement (no cell phones get signal there - its a fortress lol). I am on 4.0.3 as well. I have read that the 4.0.4 has improved radio... so it may be worth looking into. I saw a WIP 4.0.4 GSM Rom here.

I've been experiencing this as well. I'll have a great signal, then suddenly it totally disappears, and after a few seconds the signal comes back. It's even happened during voice calls as well. I experienced this on the stock device (4.0.1). I'm now using the GummyNex rom on 4.0.3 (w/ a stock radio), and I'm still experiencing these random signal loses. (T-mobile USA in NYC, btw).
It's not a constant problem, but it happens a few times a day. enough to be an mild annoyance.

Hmmmmm... I ONLY seem to get these signal drops on 4.0.3... Weird... You have a GSM device right? Not CDMA - LTE?

I found something new to try when I get home but if anyone may want to try it now and post your results it would be very helpful and appreciated.
This is a radio from the Japanese variant of the GNEX and most people who have tried it have had good success with it... See the link below...

I THINK I am experiencing this. My phone keeps going from H+ to 3G non stop at the top. How can you tell if your signal is being dropped? (sorry new to this) I've seen posts with a network screen? showing connection but I can't seem to find this.

Haven't had any issues as far as that. There were times when I was using the browser and it said network error but everything still worked.

You will notice because the signal bars icon will go "completely blank" and for example... If you are on your lockscreen and you can see the name of your provider...It will disappear completely for a couple of seconds and then come back...

No I guess I am not experiencing this. I'm not exactly sure what the difference between H+ and 3G is but my phone seems to stay in 3G until it transfers data, when its transferring data, it goes into H+, then back into 3G. Maybe this is normal. I was just curious because I did flash Yakju and the radios when i bought it.

Well, when I first flashed 4.0.1 yakju I got notifications of being able to upgrade it OTA. However, at the time I must of messed something up when I flashed it because the updates werent successful when I went to update it. So I got fed up with it and I flashed 4.0.2 manually via fastboot.

So I flashed this radio and I get SOMEWHAT better stability but it only accesses the EDGE network and NO 3G/H... Guess this is a no go too...

HD Rom, Latest build.
Radio - XXKK6
Had the stock radio with the HD Rom, and thought that my random lost connections on market were due to my not flashing the recommended radio. Flashed the recommended radio (current), and still experienced them. Signal is better, and oddly enough voice doesn't get lost. Phone doesn't show that there is no signal, in fact it is at 3 bars on H.
Edit: I use a regional carrier, that doesn't list APN settings. By leaving APN type blank, I seemed to have solved the problem. Also dramatically increased the signal strength (Using Network Signal app).

What is the name of this network signal app? Developers name and what does it do exactly?

[SOLVED] Low/No signal and low/no data connection.

Hey,
I noticed that around two days ago my HOX started acting up.
It has low to no signal most of the time, no data connection, or it shows the data connection with the "E" letter.
I have rooted it long time ago, and ran RENOVATED rom, and had no problems. it started without me doing any alterations.
So I switched to Revolution to make sure it is not rom related, and the issue persists.
Any ideas what could be the problem? tried searching for it, nothing seemed useful.
Phone details:
Kernel version: 3.1.10
Baseband version: 5.1204.162.29
Build number: 3.14.401.31 CL128187 release-keys
Thanks!
SOLVED: Read below for details.

i suggest changing networks to make sure its not a network related issue

Changing the network, by that you mean trying to change the SIM?
I have tested another SIM and I still had the same issues. and my SIM seemed to be working fine on another device.
GetLIR reported that I have the correct versions. I am really clueless as to what is the problem..

yeah that's what i meant - did you try a factory reset ?
And if that doesn't help either i think you should backup everything and get back to stock then start everything again from square 1 .
why fix it if it ain't broken ?

I have opened it, and saw that the signal cable was not connected all the way. connected it, put it back and I now have 5 bars. YAY

hi!
thank you for your post, did you by any chance take pictures of where that cable is?
and how dificult it is to reach it?
my phone is under warranty, actually just came from service, and now im having bad signal reception, in the same areas where my previous "i" phone had full bars allways and no problems with signal, no drop outs, nothing,
and with Hox is almost very low, or no signal, and constant breakups in withing calls.
sending it back to service is pain in the ass, its far, postage, time to wait for them to fix it, again....

[Q] Still have that signal issue... Any advice appreciated.

First off, I've read dozens of threads relating to this issue and no one seems to have come up with a solid, concrete answer, apart from returning phones for a replacement (and often still having the issue).
I recently acquired a Gnex second hand that has presented the signal loss issue. I am coming from a Nexus S which gets full blue HSDPA bars of signal indoors on my desk. When I place the same sim into the Gnex, I get nothing but an X. Every now and then it registers on the network (Showing "YES OPTUS" - my provider here in Australia), but still no signal.
When I got the phone it was running Android Revolution HD 9.0 with a non-stock kernel (I didn't take note before wiping the device). No luck there with signal. I then flashed to 4.2.2 under Android Revolution HD 10.0. Still no signal. Since then I have tried:
- Lean Kernel
- Air Kernel
- SlimBean Rom
- About half a dozen different modems/basebands, local, european, north american, etc. Finally settled on XXLA02 as that was recommended for Australian users that aren't on Telstra/Vodafone (850MHZ).
- Matching RIL's to the basebands
None of the above options made an improvement. On the air kernel, I would see the signal (using *#*#4636#*#*) chance from UMTS to EDGE to GPRS to HSDPA to EDGE etc over and over, sometimes showing one grey bar on Edge. I could go outside and see one grey HSDPA bar stay there, but you still couldn't use data. Browsers would fail and the playstore wouldn't open without a connection.
As of today I have restored the phone using fastboot to the earliest available Google factory image (4.0.4). I unrooted the phone and relocked the bootloader, just back to complete stock. The modem that comes with the google image is XXLA02. In this current state, there is still no signal inside, where I would have full bars on the Nexus S, but when outside fiddling with the service menu, selecting AUS from the GSM/UMTS band selection menu gave me a reasonable HSDPA signal. Though it was erratic. It would fluctuate from 3/4 to 0/4, to 1/4 over and over and both upstream and downstream indicators would be going, yet nothing was coming through.
Trying to open the playstore was awful, but it eventually worked. I managed to get the Speedtest.net app down after a few failed attempts and ran a test to the nearest OPTUS server. The results came back as:
Ping: 235ms
D/L: 576kbps
U/L: 35kbps
Which is not very good, really. As soon as I walked back inside to get the Nexus S, though, the signal dropped right away to nothing.
I took the sim out, tried the same test with the Nexus S in the same spot outside and got the following results:
Ping: 145ms
D/L: 2241kbps
U/L: 1169kbps
Which is a bit more typical for the area.
So I'm running out of ideas
As the phone was bought second hand, I don't have anywhere I can return the phone to for a replacement. Unless I contact Google directly, I don't think that will be of any help, really. Is there anything else left I could try, or is this just an expensive paperweight?
Thanks for reading.

By typing *#06# IMEI code on the display that appears is identical to the one on the box or under the battery?

[Q] Network signal drop

Hello guys, first off I have an ATT S3 running the latest PA beta with quantum kernel.
Now my query, sometimes i have a strong signal and then it suddenly disappears, i mean from a strong signal to a no signal and it takes approximately 2 minutes to get it back again. My baseband is the latest anyways and i always have LTE on.
Btw even though i tried switching the signal mode it still doesn't work, any help would be appreciated thanks.
Sent from my SAMSUNG-SGH-I747

It has something to do with a LTE bug, many people have had it. I actually have it currently on my S3 with Quantum ROM.
From what I have found and read is that we have to go back to stock ROM, though it is "complicated" that it might brick our phones with an increased percentage... I am looking for guides on helping me go back to stock, but everything is so unorganized on here and many more experienced users don't like to help others who have problems. They just tell us what is needed without the aide that might help prevent a brick..
What I do know is that you need to go back to an old bootloader but you can't go back to an old bootloader..
I will be following this thread for some help, mine didn't get any help.

I have the same problem. Anyone have a fix?

I had the issue in the past. I fixed it by going back to stock with Odin. Some have said you can also fix by flashing a TW ROM. I have not tested it that way though.
Not sure but I believe going back to stock depends on which bootloader your on.
