Screen not coming on after deep sleep - Motorola Droid 4

My screen has been failing to come on after deep sleep. The touch screen still works and restarting the phone brings the screen back to life but i am at a loss to figure out what's causing the issue.
Any ideas?

Do you by any chance have setCPU installed or a similar program that changes the CPU speeds?

No setcpu or anything like it. I tried installing cm10.1 to see if it was a software error and in cm it happens about 1 in 10 times I open/close the keyboard.

WIFI sleep policy on CM7

Hey guys,
ever since I used CM7 on my Galaxy it puts the WIFI in sleep mode as soon as i turn the screen off. I've set the sleep policy to never but yet it slows the datarate down first and then some seconds later it is stuck at 0 kb/s. That's very annoying especially if you download some bigger files. Is that a known bug on CM7 or is it just me?
Come on, i am the only one with that problem? :/
I don't have this problem, download continues even if the screen is locked...

When I was using CM7 a while back I had this same issue. Had to make sure screen was on all the time. This and some other small issues made me switch back to Darky's ROM which lags like crazy, but at least has good battery life and is stable.
Are you sure? Even same speed as with screen turned on? How in the blue does it work for you? I've had this issue on every nightly so far
Ever tried another modem/kernel?

Try this:

I've tried several modems. Currently i'm on JVQ... As kernel I only tried Fugumod so far... but i seems like it works for others :/
@mobidzid
I've tried this and other apps who keep connection alive, but they have no effect at all for me :/
I have the opposite for MIUI rom.
The MIUI rom by default set the WIFI in sleep mode as soon as the screen is turned off. However, from the battery history, the WIFI never go to sleep. Is this a problem with MIUI rom or there are other setting required?
Nothing new on this? It really drives me crazy here
Please delete, I wrote into the wrong thread... :O

4.2 gets stuck I'm deep sleep, could it be the case?

I haven't seen this mentioned anywhere else, and its getting very frustrating. Last night my N7 shut down from low battery, after plugging in, it still wouldn't start up. I got it going again holding firm the power and volume button, but now it's constantly either freezing during use, slightly after startup or not turning on at all after gong to sleep.
I factory reset and that seems to have fixed the lockup issue but it's still getting stuck in deep sleep. The only thing I can guess is that it's the magnet feature in my case that is causing it. I've now had the case off for about an hour and had no lockups.
I've never felt the need to root this thing but I'm thinking of routing and fling to a custom 4.1.2 to see if this fixed it.
Has anyone heard of or had this issue before?

More: its got nothing to do with the case, I've had multiple lockups over the past hour and now a isn't even get past the lock screen without it locking up. Only setting I changed was killing the auto brightness.
No one else is having issues like this?

nexus 7 not killing wifi during sleep after updating to 4.2.1

I have selected to never keep WiFi on during sleep yet now the tablet continues to run the WiFi as you can see in the pictures. This has forced me to use airplane mode when I am on the go because otherwise the tablet just keeps WiFi on and burns the battery extremely quick. This has been a problem since I updated to 4.2.1. I am not rooted completely stock. A solution would be great because this sucks right now. I have tried clearing the cache in recovery but that didn't solve the problem.
I'm running the latest Paranoidandroid ROM and thought that was the problem. I can't yet post to that developer forum so I was just waiting for the next beta.
I guess it's a problem with 4.2.1 then.

If you don't find a solution you may want to try DataEasyPro from the market. It kills both 3g and wifi as soon as the screen is off and then runs a user defined schedule to turn on 3g or wifi every now and the for a few seconds to keep you upto date with your social world. Works great. There is even a widget so you can turn off the schedule when you are downloading or updating from the play store.

I think it is a 4.2.1 problem. Its hard to say how wide spread it is though because I have only seen a handful of posts about this issue though. To me, this issue is unacceptable. I should not have to enable/disable airplane mode to conserve battery. Especially when the previous version of android prior to the 4.2.1 update handled WiFi sleep settings without a problem. Hopefully a fix will be here soon. My tablet used to have superb battery life without me constantly monitoring it. Now I feel like I have to keep double checking that I remember to use airplane mode so that I don't go to use the tablet and find a nearly depleted battery.

I recommend automate it, I have a couple of rules set to turn WiFi of with the screen (with a 5min delay), then turn Wi-Fi back on when the screen turns on. There's plenty of other settings and rules to play with as well.

In had the same issue. I found Google maps to be the culprit.
It defaulted back to location reporting.
Check Google now sync, maps and currents.
Sent from my Nexus 7 using xda app-developers app
It's not google maps itself, it's the android location service. It's always collecting data even if your phone or tabscreen isn't on. This is pretty anoying since google only let you choose between agreeing to run the service in the background or not using it at all. Stupid! How about collecting data only when the device is in use?
Same here. There is a bug report on Google about it.

Ah this is interesting; as last night my battery was on 53% and I am sure I charged it fully previously...... Am on stock too but have rooted.
Might just switch the tablet off all the time for the time being.
I'm on stock rooted 4.2.1 and mine is fine. Strange.

WiFi turns off here also, which means its working as intended, what is strange is is it not working for some people, I'm also on stock rooted 4.2.1.
what is the OP using? Are there any apps installed/running on the OPs device that can keep the WiFi alive?

I highly recommend using an app called Better Battery Stats. You can find the free version here on XDA. It'll tell you if there is an app causing a wakelock. I used it to troubleshoot my Rezound and I'm getting a solid 4-5 hours of screen on time with the extended battery on that because it helped me lock down the apps that were killing my battery.

I'm stock rooted and mines don't turn off neither.

Hmmm. Just checked PA beta 7 and it's doing it too. Wifi on always.
A custom kernel would probably fix that.

Although my wifi is turning off I give thanks for pointing me in the direction of this app.

I was having the wifi on issue as well. Just bought my N7, stock 4.2.1 and not rooted. I followed the tip in point four of this post, which details a simple set up using Tasker, where the unit turns the wifi on and off after the screen turns on or off respectively. The reason for the 10 second delay as is detailed in the link, is to allow for the turning on of your N7 to check the time or other reasons, and then quickly turn it off without the wifi on task being activated.
the screenshot below shows my wifi being stuck on while in sleep mode, even with it set to be never on during sleep in the settings, and the change in behavior once the 2 Tasker profiles we set up.
Cheers
Those of you having issues, have you tried the "only when plugged in" setting? Not sure if it would really matter but that's what I use and mine turns on and off just fine.

Testing that now. Turned off Tasker, and set wifi to the "only when plugged in" setting. It's only been about 30 minutes, but so far it looks like it's behaving the same as before, as in keeping wifi on while in sleep. I'll Let it sleep for a few hours and see what the chart shows.
Cheers
EDIT: So I let my N7 sit for about an hour after switching the above mentioned settings, and you can see in the screenshot below that the wifi is staying on while the unit is not awake. I've set my Tasker profiles to control the wifi once again.
I know it may be fixed by a factory reset, but frankly I'm more than happy with the way Tasker handles the issue.
Cheers
so 6 months later, I am still getting this problem. However it seems only to be with the last update. The tasker method seems to be working well though.

Black Screen Of Death Cause

This happened twice to be due to doing the same exact thing.
I found out that while a YouTube video is playing with your headset connect, switch the screen off with the headset connected overnight and then in the morning the device will not switch on the screen but the notification light was going so the only way to get out of it is to force power off by press and holding the power button for 10 seconds until the device powers off.

Is the cpu undervolted, and if so by how much and try less undervolting and see what happens? Or try clearing the YouTube app data.

I did not mess around with the CPU over/under clocking so no but maybe the system did that by itself.
I did find some other bugs in the system, sometimes I wish that I don't find bugs in the Android System but yet I find them.

The cpu doesn`t get undervolted by the system spontaniously and by itself. If you found system bugs post them and probably there are fixes or workarounds for them

That's the problem, I did post the bugs before but people don't reply at all.
EDIT: Maybe YouTube uses a certain CPU value BUT the screen was off so it was using the invalid value causing the screen to not come on.

[Q] Logging? Phone shutting down (SwG 2.06)

Running flex's SwG 2.06. A few times since migrating to 4.3 my device has "shutdown" where it goes from launcher to an htc screen like when you power off/reboot the device. Earlier I let it sit like that for 5+ minutes as I packed my bag to hit the road and went down to my car. Still at the same screen when I got to my car. Had to manually power off and back on by holding the power button till it turned off.
I don't know if it's 4.3, rom or app related. Is there something I can run that wont destroy my battery that'll log or something to give me anything to diagnose my issue? I don't seem to have any abnormal battery usage... I think...
Thanks
Download alogcat from the playstore, or rewipe and reflash.
