Impenetrable WIFI Sleep Problem

After checking couple of forums, I realized that this is a general bug for Android. Many people complain about it but it seems nobody could find an exact solution. I will try to explain the problem to be more precise.
Even though "Keep Wi-Fi on during sleep" is checked as "Always", when the phone goes to sleep it doesn't connect to internet.
Wifi signal shows it is connected but it is not. I have to disable/enable wifi in order to make it work.
You can see many posts regarding to this issue. It looks like people acquiesced the problem since nobody found an exact problem.
Is there any solution that you could find?

I have GSM Nexus also.
I bought it 3 days ago. I noticed it right after I powered it on. I had similar issue with my HTC Desire.
Now I installed a ROM to try it and still no luck. I started to think that problem is because of modem.
What ROM & Kernel are you using?

This happens to me. I picked up some gameloft games in the 99 cent sale and downloading 800mb over wifi is impossible. The screen turns off and the download fails.
I found I have to set the screen to stay on when on USB, plug it into a wall, and download.
I've been on several roms. I haven't started experimenting with kernels but thats the fix I think in this case. Even CM roms do this. Hopefully it isn't hard coded into the hardware.

You could set your screen sleep policy to wait 30minutes to turn off. Surely wouldn't take longer than that.

+1...downloading game loft games is not possible. The game only downloads on wifi but the download stops after the screen goes to sleep.
Edit: Just tried downloading 300mb of game loft game data and it works even when screen is off. Im on AOKP BUILD 17, I definitely had this problem on stock 4.0.2.

I had the same problem with my stock rom. I still have problem. I didn't try any other rom until now. I think I should give a try.

I am my second Galaxy Nexus due to other issues. The first one did not have this wifi sleep issue, but my current GN does ( I installed a VOIP app on the second that was not on the first... not sure if this has anything to do with the wifi sleep issue). I think I may have found a work around. I changed the setting to never and tested a few times. Then I changed it to always again and now wifi remains on while the phone sleeps. I have tested it a few times and so far it is still working. I will update the post if the problem reoccurs.
Stock ROM (4.0.2)

You know what,I have the opposite issue.my wifi never shuts off.... I just leave it.wifi on this is way way way more battery efficient than my galaxy s. Even the cell radios are pretty awesome. Hardly take any battery at all.

I updated my kernel and its fixed. Downloaded MC3 finally.

[Q] Continous Vibration

Hello people!
I am a new member with XDA Developers
Anyways, I would like to ask if any of you face this problem where at any random time the phone would start vibrating continously until you shut down the phone and is there a fix for this?

Hello and welcome the the XDA Forum!
I've found at time that the app "Whatsapp" when I get a message, My phone will constantly vibrate until the screen goes off for 5-10 seconds then it's fine until I turn the screen / unlock the phone, I think it's a common problem as I remember someone else had this issue.

Yes i also found that too, but sometimes I encounter the problem with SMS too. Never encountered this problem with my previous phones, the GALAXY Ace (GT-S5830) and the GALAXY 3 (GT-I5801)

It hasn't done it for SMS for me but yeah it never did it on my previous phone either ZTE Blade

When my profile switch app change profile and take phone to silent mode sometimes makes my W too...
The only solution reboot...

Looks like this affects all GALAXY W's

Yes, and it happens always the best time... meetings, driving...etc.

never happen to me
but if it happened, I'll flash a new fresh ROM and see if it solves the problem

Happens to mine, seems like it was only when Whatsapp and something else had a notification at the same time.

that's weird, mine never experience it
I have tried stock, Bagux's, Blacknote, Kezra, and deodexed rom.
maybe something to do with HW version?

Unfortunately mine too. No more idea.

Damn, mine is also REV 0.6 as well.

Still same problem
Mine also rev 0.6
Tried Rebel Rom, Bagux, Bionic Cow 2 v 7, stock DXLM3, stock XXLM8 , all still has the same random vibration.
And the vibration won't stop until you reboot.
Probably hardware related?

This happens to me since the first day I got this phone...
Honestly, it's annoying me !
Cause the only way to Stop it, is a reboot..
Sometimes it starts to vibrate in school, and as Im using a TPU SoftCase it's even more uncomfortable...
I thaught I was the only one, but seems like it affects all Wonders..
No matter which Rom I use, everytime the same Problem
A random time.

[Q] No MMS Notifications Sound?

Greetings once again,
I am using GO SMS Pro and for some reason when I get an MMS I get no notification sound and no vibration. The screen will pop on, but I get no other notification. I tried disabling GO SMS and using the native Messaging app, but it still persists.
Anyone know what this issue is?

I dont know if this is carrier specific. I dont know what service you use but I have a Verizon Galaxy Nexus, rooted, custom ROM and all. I have had this problem before. On CM 10.1, I never had this issue. On a couple others I did which made me switch back to CM. I would get a notification (vibration, light) but when I turned the screen on, there was nothing there. Or I just would not get other peoples texts all together. I dont know what the issue is though or what causes it.

Yeah, the ROMs I used that had that issue were AOKP based. Carbon Rom and JBSorcery. Both started having this issue. Although, Carbon ROM was fine when I first started using it. But like I said, I have never had that issue with CM so I dont know if its a ROM problem or what. I cant explain it. Thats what always kept me going back to CM.

Ive been having the same issue, I think I first noticed it after I went to 4.2 (aokp)

I've never had this problem before. I'm having it on Carbon ROM nightlies right now. I've even tried re-applying the sounds, choosing different sounds, and re-flashing the ROM or another nightly and I still have the same problem. What gives?!?!

Am not a nerd but go get it replaced. If it's new and has such issues, theres no point trying to fix it yourself when you can just get a brand new device.

Yeah i thought of that, but its very far from where i am now, i will not mind fixing it if only its a software problem, and not hardware

flickering screen
I've seen the same problem on mine which is brand new but past the 14 day store return policy.
It happens when playing video. It seems to go away after reboot, and when I open air command with the spen, which makes me think its a firmware rather than hardware issue. I've checked to see and it has the latest update at the moment.
Anyone else have any news on this problem?

Used to happen to my P601 as well. After updating to a 4.4.2 Rom (specifically P601XXUCND6) I have not experianced it anymore

Have you had a look at settings in Device->Display ?
AutoBrightness and Optimize Display can both be causes of flicker, try turning them off in the Display Settings.

Turning off hardware overlay in developer options worked for me. Don't know why everything was fine the 1st week or so I had it and then all of a sudden with the flickering. Guessing it may be a cache issue or something but whatever, this worked.

Flickering Screen on Galaxy Note 10.1
Hi There
Have you figured out the solution to this?
I have purchased the Note 10.1 last week and Samsung has informed me that they will not replace it but that it would have to go for repairs.
I too have restored the factory settings and turned off all settings for the S-pen as advised yet the screen flickers even sometimes on the home screen! I have also turned off the auto-brightness.
How/Where can I turn off the hardware overlay ??
Does anyone have a solution for me please?

[Q] Problem with proximity sensor L900 with CarbonROM

Hello everyone, as my title states. I am having a problem with my proximity sensor when in a call. I have a sprint galaxy note 2 (L900) and am currently running CarbonROM's nightlies (4.4.2). Before I was using the 4/10/14 nightlie and when I was in a call the sensor was stuck and kept my phone dark until the call ended. But now with the 4/17/14 nightlie, the phone is constantly on while in a call. Has anyone else have this issue using CarbonROM? If there's a fix please let me know. Much appreciated.

I'm currently on Carbon ROM nightly version 4-17 and I have the same issue. Did you find any info on this bug in the Carbon ROM forum? I think this needs to be looked into because I don't like face dialing while talking on the phone. lol

No I didn't find any fixes for it. I talked to one of the developers and they are looking into it BC when I entered the live chat I asked the same question and they responded with "let me guess, note 2?"they're not sure what's going on with the notes that is causing the bug. But I've been looking at the change logs hoping they fix it and my phone volume is really low when I'm talking to someone as well. Sometimes I can't even hear the caller so I have to switch to speaker :/

Thanks for the reply. As for the low volume during calls. You may already know this but try lowering the volume then raise it back up and that should increase the volume a lot. It's a bug in some AOSP ROMS.

I have tried that and sometimes it works and sometimes it doesn't, unfortunately.

The proximity sensor issue has been fixed in the latest nightly build 4-23. Although now I can't sync my browser in Google account sync settings. All others seem to sync except browser. Could be another bug...
