Ever since I put Jelly Bean on my VZW Galaxy Nexus, if I connect to WiFi and let the screen go to sleep, after a while (ranges from a couple minutes to an hour or so) my WiFi icon will turn grey. It stays this way after I wake up the screen and I won't have Internet connectivity.
I only experience this issue on my home WiFi network. It does not happen on mobile data or my workplace WiFi (which is using WPA2 security like my home network). This issue also has occurred on every Jelly Bean ROM I've tried (stock rooted JB, a couple early CM10 hybrids, Bugless Beast, AOKP build 1 and now CM10 nightlies).
I wanted to test some bare-bones scenarios so I did a clean install of the 8/22/12 CM10 nightly build last night (wipe data / factory reset, format system, wipe dalvik cache, flash CM10, flash gapps, boot). On first boot I connected to WiFi but did not sign in to my Google account or set anything else up. I hooked it up to my computer and ran an adb logcat all night, but the icon stayed blue when I checked this morning.
Since I had no issues in this scenario, I then added my Google account and updated the Gmail app when prompted. Other than that, no change, still haven't even launched an app. Ran another adb logcat and within 10 minutes I started noticing connectivity issues in my logcat so I turned on the screen to check, and sure enough, my WiFi icon was grey.
Attached is the log from the bare bones CM10 after I signed into my Google account and let the screen fall asleep with a blue WiFi icon.
If anyone has any troubleshooting ideas from here, I'd really appreciate the help!
EDIT: Ran a new logcat showing the actual connection process, although this time after noticing the connection issues in the log and turning my screen on, the icon only stayed grey for a few seconds and then turned blue. This is adb-log-2.txt attached.
I assume you already messed with the WiFi sleep settings, right? Also, I read another post explaining that the bars turn from blue to gray when you are not connected to any google services. Not sure if that's true or not.
Anyway, I see the same behavior on my phone at times and although it never bothered me, now I want to know what cause it as well...
Same problem on CM10.
Hi guys,
I have this problem too, in Cyanogen Mod 10. Galaxy Tab 10.1 WiFi here.
After deep sleep (5+ minutes) WiFi locks it self off, i cant turn it back on because its grey d out.
Reboot so far, seems the only solution, a bit annoying have to reboot every time it goes to sleep, but oh well, this rom is still amazing.
Any solutions yet? I wonder trying a diferent Kernel, eve that most users posted it as useless as it keeps locking itself off. :
Cheers!
I'm also unsure of this issue but sometimes it does happen. Turn on airplane mode and then turn it off a few minutes later or reboot.
Sometimes turning off wifi will fix the issue.
To make sure just go into advanced and turn off avoid low signal thing in wifi if you haven't already.
Also unfortunately some routers are picky on our WiFi drivers as with other phones. It is also ROM related too.
I had a droid incredible and on sense 3.5 it always lost WiFi and signal every 50 minutes to an hour.

So yeah, I have been noticing that my Desire running on the latest MildWild software (and Cyanogenmod 7.2) for that matter has been trouble keeping it's connection constant on Whatsapp.
Basically, it stops 'reporting' when it comes to 'last seen'. Sometimes I have to turn off Wifi (It is mostly on Wifi, can't recall it being the same story on 3G but I think so too) to fix the connection. Other times it just reconnects after a minute.
This happens when the screen is turned off and back on.
It's getting a kind of annoying and I have no idea where to look. I've checked my modem and router and both are fine.
Anyone else with this problem? Any ideas how I can fix this? Also, Wifi Sleep Policy has been set to 'Never'.

Have you tried reflashing your current ROM? Wipe Cache/Dalvik? Wipe everything? Plenty of things to do!
Reboot your phone.
If that doesn't help, then go into settings/more/data and back up your APN. Then reset it to defaults.
Also check the simple things. I had a similar issue one time were some how airplane mode got turned on. If all that fails reflash and wipe everything. make sure you have abck up of all your settings. if none of that work call you provider and make sure they dont have it blocked for some reason. Also you may try flashing a new radio file.

i'm on at&t. this happened to me about 6 months ago. here's where it gets interesting: my wife and i both were on S2s at the time and we BOTH had the same thing happen at the same exact time. i was texting at work and noticed the gray bars. i had just been browsing the web 10 minutes prior with the blue signal bars. i texted her and told her i dont have data. she replied back and notified me that she too just got the gray bars and no connection. we were both running 2 completely different roms and kernels. she had been on her rom for 2 weeks and me for 3 months.
at&t said we looked fine on their computers and didnt know why we werent getting data. my wife slipped and told them we were rooted and we didnt get any more useful help after that. randomly, about 6 hours later the connection/data came back and we never saw the issue again
I received a brand new Galaxy Note 4 from Sprint a few months ago to replace a problematic LG G2, but didn't activate it until last week (it sat in it's box prior to that and wasn't even turned on). At first, it worked great, but recently it has been losing Bluetooth and 2.4 GHz (I think) WiFi connectivity every day or so (usually when I wake up in the morning), and the only way to get it back is to restart the phone.
Has anyone heard of this? Or have any suggestions on troubleshooting or resolutions?
Thanks very much!
Three things to mention:
1) I did the tap & go to transfer my data from my old LG G2 (running some version of Android 4.x - I can't remember which one specifically) to my Note 4, but that was a week or so ago and the problems only started in the last few days.
2) The Note 4 came with a version of Android 4.x, but I updated it to Android Lollipop - again, this was done a week or so ago and the device seemed to work with no issues after doing it.
3) I am using the Samsung Gear 2 watch with the phone via Bluetooth but it seems all BT connectivity dies when the above issue happens (such as no ability to connect it to my car BT, etc.)
Thanks for any assistance!
Have you changed the visibility timeout to never? Then keep Wi-Fi on during sleep? For the Bluetooth problem, which I had also,I did a factory reset and haven't had as many problems since.

Thanks for the info. I haven't ever made any of those setting changes previously, which is what leads me to believe something is wrong. For Bluetooth visibility, it is set to "2 minutes", but wouldn't this just be when a device is initially connecting to my phone, and not when a device is already connected? And for WiFi, it is set to "Always" for "Keep Wi-Fi on during sleep", so this is already set per your suggestion. Basically, things used to work fine, and now every night it seems to lose BT and 2.4 GHz WiFi. Per suggestions on another forum, I did a cache partition wipe, but this doesn't seem to have helped. This morning I woke up, and the device had lost it's connection with my 2.4 GHz WiFi network (wasn't even seeing it), and had connected to my 5 GHz WiFi network, and while it still showed connected to my Samsung Gear 2 watch, I don't think BT was working since I tried to connect it to another BT device and it failed. I then restarted, and it worked fine (until tomorrow morning presumably). I'd prefer not to hard reset, especially since there's no guarantee doing so will fix the issue and it won't just re-occur, and because it'll take me a lot of time to back everything up, hard reset, and then restore data, settings, and customizations to my device.
Any other suggestions or thoughts? Thanks!
I just wanted to say that my connectivity timeout is set to two minutes as well. I use my BT everyday for my headset and my head unit in my big truck and have had no issues.

Thanks for the info! This is so frustrating - just started using this device, and already it's broken...lol! Anyone have any other good thoughts or suggestions on what I might be able to do to resolve without a hard reset? Thanks!
Any other thoughts/suggestions? I'm open to Anything at this point!!
I spoke with someone at Sprint Tech Support, and they had me turn off WiFi Power Save Mode using *#0011# (and then choosing WiFi from the three dots menu) to see if this would help resolve the above issues. It didn't, and now even after re-enabling the power save mode, things have gotten worse. Now, every time I leave a location where I'm on WiFi (such as my home), my device's WiFi never refreshes to auto reconnect to other WiFi SSID's elsewhere. So even if I leave my home and arrive at an office where I've previously saved a WiFi connection, the phone stays on 4G/LTE until I manually turn off WiFi and then turn it back on a minute or so later. And I still think the 2.4 GHz issue (above) is happening as well.
WiFi is basically useless on my phone now - anyone have any ideas at all?
Thanks!
I work in an office thats underground, Cell reception is almost non-existent. So I depend on WiFi to keep my phone in touch with the 'net. Otherwise, my battery just drains before lunch time.
Because of this, I have to make sure that my phone DOES NOT turn off wifi while it's asleep. Otherwise, while its sleeping, it will just eat up the battery as my phone tries to report my every action to Google, and check my email.
I had this working perfectly, and then I decided to try out Android N developer preview, used it for a few days, and then factory reset the phone to go back to M. No big deal, I've done this sort of thing a thousand times with my various phones, and this is part of why I bought a Nexus this time around.
After the reset, I cant seem to convince my phone to keep it's wifi on during sleep. The option is set in the advanced wifi settings to keep wifi on during sleep always. Yet every time i turn off the screen and set my phone down, it goes silent, until I pick it up and unlock it. If it sits long enough, when I unlock it, I actually see the wifi icon missing from my status bar, and it comes on after a few second,s and then the notifications come flooding in. It's obviously doing something that disables wifi when the screen is not active.
This is killing my battery, because even though wifi is off, it's still doing its thing, trying to keep in touch with its various sync services. Its attempting to depend on cell service, which most of the time is flat out non-existent at my desk.
So what can I do to fix this? Is it possible something didnt get cleanly wiped when I reinstalled the stock rom after my foray into N? I've tried doing things like wiping dalvik, but that hasnt helped. I've also received the April OTA since then, and nothing regarding th WiFi problem has changed.
Any suggestions?
Thanks!
The only thing I can think to try is removing your known WiFi networks and adding it back.
In the mean time as a work around, you can disable mobile data so when WiFi does drop out it switches over to a voice only signal.

I have tried clearing out the saved wifi network for work, and re-joining it. Didnt help. I even went so far as to have the network guys de-authorize my phone, so when i rejoined it would be like it was never there before. Also didnt help.
What were the steps you took to return to stock?
Hi everyone,
I have 2 Galaxy S8+ from Verizon and here are my issues:
Past issues:
One of them did not come with the Galaxy Apps store (Not the plays store), and that phone also experienced the DQA issue
Current issues:
If I turn on Fingerprint gestures, the fingerprint sensor will stop working, this was an issue I had from the day I got the phone and has continued even through the updates. Here's a thread I made about it a while ago : https://forum.xda-developers.com/galaxy-s8+/help/fingerprint-sensor-t3595614
My internal speaker has detached, or at least I think that is the issue, as sometimes when I am in a phone call and shake the phone just a little bit, it will either start making a weird buzz sound or completely cut off the sound. Shaking it again will fix it, that's why I think it's a physical issue. I haven't dropped my phone and just in case I ever do, I have a case and a screen protector on it, and neither of them (phone, case, screen protector) have any damage marks on them.
The Biggest Issue: Currently this is the most annoying bug I am experiencing is that whenever I go to lock screen and security in the setting app, it crashes the settings app. I also can't use the search function in the settings app, as it crashes the app withing a few seconds. The lock screen and security is the only menu in which I experience this, I am 99% sure this is due to me turning on Secure startup. I had it turned on a few days after I got the phone and it worked great, I had to turn it off once, about a month ago in order to get a quicker boot. After that I was experiencing issues turning it back on (meaning I turned it on, rebooted the phone and it would not work) , after some persistence, I was able to get it to work and it has worked and still works.
One thing to mention is that I had done the most recent system update, I am not sure this issue was caused by at, since the inability so search in the setting menu has happened prior to the latest update.
I have tried everything other than a full factory reset (wiping all cache, wiping apps cache, reset setting, reset network settings), which I refuse to do, It is absolutely unacceptable for me to pay this much for this phone and have so many issues with it, I have factory resetted my phone (Samsung's recommendation) in order to fix the first issue listed above, multiple times and it did not work.
At this point I really don't know what to do, Samsung support has been useless in this, I don't wish to replace my phone right now as I need it to much to even give up for one day, If anyone has any advice/fix other than factory resetting, I'll happily try it.
Thank you,
GGgamer16
Sounds like a factory reset is needed. I just tried all you mentioned with zero problems on the newest update w/ navbar options and experienced none of that. Speaker problem is most likely hardware related.
Anyone had any luck getting rid of the wifi disconnect? The issue where wifi disconnects showing a ! next to the wifi symbol on the status bar?

You try changing your WiFi channel? Using 5ghz or 2.5ghz? I use Wifi 100% of the time I'm home and never have any issues with disconnects.

Yeah I have tried changing channels. It didn't matter. I'm on 2.4 GHz.
I found a possible fix from another forum. I changed my wifi encryption from wpa2 AES/tkip to wpa2 tkip only last night and was rock solid after that point. I didn't have any more wifi issues... Just wanted to mention this change for other people. I usually got 5+disconnects every night. I'm gonna try just the AES option tonight and see how it acts.
