[Q] Screen Won't Wake Up? - Epic 4G Q&A, Help & Troubleshooting

Hi everybody,
After running stock DK28 for a while, I decided to give rooting a try. I was able to root with no problem. However, after a couple days now, I have noticed that when my screen times out, sometimes it is unable to wake up. In other words, the screen turns off, and will not turn back on despite how many times I press the power button. The only way I am able to fix this is by taking out the battery and re-starting the phone.
The problem seems to be very intermittent and random at best. Any ideas what may be causing this?
Also on an unrelated note, I have noticed that if I leave my screen open and allow the phone to time out, the physical keyboard will light up and turn off several times by itself (this has been going on since I installed DK28). Not necessarily a problem, but kind of weird.
Thanks in advance for the advice!

Do you have setCPU ?
i know sometimes when people set screen off properties to low it freezes and needs a batt pull

Funny enough, I guess the problem started after I installed that. I cleared its settings and cache and uninstalled the program hoping it would fix it, but no dice. I figured that would fix the issue if it was related

i guess reinstall it and set the screen off properties a little higher maybe
400 max
100 min
ondemand
(My settings)
or play with the settings till it fixes since im guessing you never reinstalled the rom your on

I tried that once, didn't seem to help but I will give it another shot.
I am running stock DK28 ROM, maybe a fresh install will help?

o and you wouldn't happen to be on viper rom would you ?

Set it at 200 min.

not running viper ROM. I am running stock froyo with root access.
DiGi: Is that what you have it set on? I thought I read somewhere not to set it that low.

I was running on 200 min just fine. I haven't had setcpu on my phone for a little while though. I think 100 is too low and causing the problem. 200 didn't cause crashes for me.

I've been playing with the settings on SetCPU but to no avail. My screen still won't wake up at random.
Any other thoughts? I have again, un-installed SetCPU and am no longer using it but the problem still occurs.

Recently changed my phone to android and my phone wouldn't wake up every time it goes to sleep more. (Radio 2.10.50.2)
looked and tried a lot of suggestions (format SD, flash ROM, update setup.txt file and etc) but nothing worked until I flashed the new radio 2.14.50.
And it's been working fine for a day now (finger crossed).

Do you have adjbrightness? Theres a problem with it on galaxy s phone where it won't wake up that they haven't been able to fix and that may be your problem.

Did you ever figure out how to fix this "no wake up" issue? I had this problem out of the box with my mini. So does my friend.

[Q] CM7 eventually just starts showing black screens instead of most things. Why?

This problem only really happens after my phone has been on for days at a time. I have had this problem on the latest stable and latest nightly for CM7 (each one cleanly installed after a total wipe).
What happens is that most screens are replaced with entirely black ones. The most consistent example of this is the settings screen. The first Settings screen (which shows Display, Sound, etc) loads correctly. If I click on any of those, I just get a black screen. This will happen in other applications too, like Baconreader or Browser. Also, another connected issue is that the lockscreen won't animate once this problem starts. I can drag it down to unlock, but the rotary wheel won't move at all. If I drag to the right to load my custom app, the lockscreen won't go away and it will force my to pull the battery.
Has anyone else run into this problem? I'd just like to know I'm not alone. I'm not really expecting a bugfix, especially when I'm not even posting a Logcat.
Did you fix permissions?

I suffered this same thing today. Thankfully a full restart fixed out, but I would love to learn a real solution.

Next time it happens I will, I'm just afraid it will break Facebook/SMS integration like I've had happen before.
It's just so weird since it breaks everything. The lockscreen, the options, Pandora's station list, the browser, and it goes on and on. It's like there's some sort of display mode that gets screwed up.

What version are you using. I'm going to try to install nightly 77 today after a fresh wipe.
I was seeing the same thing. Now I'm trying to figure out why my data speeds are so painfully slow on CM7 so I can't offer a fix. Flashing back to Warm to troubleshoot 3G.
I get these issues all the time no matter what kernel or nightly I'm running. It has forced me back to sense roms lol
Same problem here. I updated stable mod from stable mod. Reinstalled. Going on 4 days, no issues so far.
Sent from my PC36100 using XDA App
I have the same exact issue. This never happens on a sense rom. I did some tweaks to my system over the past week and I haven't had to reboot since this past Saturday or Sunday. I thought I had fixed it!
Then...
My phone started doing it this morning after I turned on 4G at work, literally as I was writing this post it started doing it. I then turned off 4G.. and it instantly went away. Turning back on 4G and it isnt doing it right now. Now my phone is doing something weird with go sms pro... when I get a text and I respond via the pop up message.. once my text moves to a second line I dont see what I am typing anymore... and now it has progressed to where the pop up box isnt refreshing after I send a message (this is all happening while I am typing this post). Now the phone has become laggy and somewhat unstable... rebooted! All is well. So I went roughly 4-5 days without a reboot... where as before I had to reboot at least once a day.
Thats about the best I can get with these settings:
CM7 7.0.3.1
Savaged Zen 2.6.38.5 CFS > Using SavagedZen Governor, min 384 max 998
Displaying some animations (read somewhere that is a "fix".. or helping extend the time it takes for the Black screen of death to appear).
This is after several full wipes, several when I was running Amon RA recovery 1.8 then updated to the latest and did it two more times. After upgrading Amon and wiping I did not use any backups and started completely from scratch.
So I am not sure what else to do. Some people are getting this, some are not.

Camera Error - Cannot connect to camera.

Anyone else getting this error? After reading the two main errors seem to be faulty camera hardware and bar code scanning apps. I uninstalled my bar code scanner and the problem persists. There is a small dent next to my flash under the camera but this came with the phone and my camera worked for a while. Taking the battery out and putting it back in fixes the problem about half of the time, but only is good for one to two uses. I'm thinking of sending this in, but I'm waiting until the SGSII HD is out in case they offer to replace it with any phone. Wishful thinking, I know.
And here's the error:
Are you on the stock rom? I got that yesterday but a reboot fixed it.

Try doing a factory reset. Sometimes an app installed on the phone might screw up with a hardware's function. For example, I've always use Screebl Pro on my phone to let it control how my screen turns off. I decided to try their new Beta version. A few days later, I cannot seem to manually turn off my screen by pressing the power button. Every time I press the power button, the screen will come back on on its own. I can try up to 4-5 times before it eventually goes off. I though my phone finally broke as I tried uninstalling and reinstalling apps, changing settings here and there to no luck. I finally realized about the beta Screebl I had installed, and decided to disable it. The moment I did that, the phone was back to normal, no weird things happening to it.
So try doing a factory reset first before sending it back.
Strangely enough uninstalling Reconage has seemed to fix this. Can anyone else confirm it breaks your camera? The comments don't say it does so it must be something with the Nitro.
I get it too on cm7 all the damn time. I can record 1 video then after I stop, it messes up and I have to reboot to record again.
Any more definitive answer on this issue? My wife's Nitro HD has started giving this error in the last few days and no amount of rebooting seems to be fixing it. She is stock plus a few apps. I uninstalled nearly everything that uses the camera, reboot the phone, and still have the problem.
Alternatively, is there a way to see what apps were installed/updated by date? The last photo she took was on 6/13, so if we can figure out what apps have been updated since then that might help us get to the bottom of the issue.

Rogers SGH-I747M: Screen turns on by itself after pressing power button

I've done a search for this problem, but haven't found a solution to this yet.
I'm running the stock rom w/root. It didn't do this when I first got it, but it's doing it more and more as time goes by. It's starting to drive me nuts, especially at night since my phone is my alarm as well. Doesn't seem to matter if the phone is charging or not.
The screen will flicker on and off a few times in a row, then stay dark for awhile then resume the on/off behavior out of nowhere. I'm not receiving texts or emails when this happens.
I have checked my account syncs, and nothing is set to automatic. Never had this behavior on my SGII LTE running ICS.

Your title made me chuckle.
I did experience some random screen wake ups while on stock that sort of just resolved themselves. Try rebooting, and then try to uninstall any new apps you've installed to see if one is causing this.

Thanks for the suggestion. Rebooting was obvious as I've done that many times. I did go through a bunch of apps and removed them, then reinstalled one by one. So far the problem has gone away, I've yet to identify which app might have caused it though.

[Q] Updated to stock JB - Now phone freezes/crashes

Hi all -
I'm on AT&T, 100% stock, non-rooted, etc. I upgraded to JB last night via Kies without issue.
However, ever since the upgrade, my phone won't go more than 5 minutes without freezing and then crashing.
It's a very odd behavior... the screen will still animate. So, if I'm playing a game with a timer, the timer will still count down. But all touch input (including menu/home/back) does nothing. Home/back don't illuminate or do anything, but they do provide haptic feedback. Power button does turn the screen on/off.
Eventually after a few minutes, the lock screen comes up with the "tip" even though I've clicked to never show it again. However, it barely registers a swipe to unlock when it freezes again. At that point, it will usually self-reboot.
I've tried to enable some of the developer options to see if maybe there was a rogue program that was incompatible with JB, and maybe causing the issue, but I couldn't see any correlations.
I really want to avoid doing a factory reset if at all possible, as I have a game that I worked really hard on to beat a few levels, and I'd hate to lose my progress.
Anyone have any ideas on what I can try?
I should note that uninstalling programs is iffy... sometimes it works, other times it just uninstalls indefinitely.
Thanks!

This sounds somewhat familiar to my experiences with JB. I rooted right away with the stock JB and had freezing / crash issues. So I then went pure stock and had issues (un-rooted). I then tried a custom TW-based ROM called BlackJelly and had issues. Now I am on CM10.1 which is AOSP JB4.2.1 based and things are even worse.
There seems to be no JB ROM that is stable for my phone. Getting very tired of this.
See my thread for details:

Strangely enough, my issue ended up going away. I think it was a rogue program that needed it's dalvik cache rebuilt. Once uninstalled, the phone worked great. Not sure what app it was.

Random reboots and more

First off I'd like to say that I've already got the power switch replaced on this device. So I've ruled that out to some extent.
That being said, my device pretty much will freeze up at random times then either turn off or reboot. If it reboots, it will load the OS (or sometimes not even finish the boot), then either freeze up then reboot again, turn off, or freeze up and stay frozen for eternity. I've tried reverting to stock then reflashing all my **** and redownloading all my apps and stuff. While that helped for maybe, 3 days, it did not fix the issue. Also notable that this usually happens several times a day, and that sometimes leaving it on the charger helps it make a stable boot. I've also purchased a new battery with no luck. Not sure if this is related but figured it might be relevant that the device wakes randomly sometimes. This is not related to my specific ROM either, this happens on several pieces of firmware. Only cause I can think of is age (this model is almost 4 years old) or a faulty power switch (I've already had the switch replaced).
This has started to affect my schedule in that my phone loves to turn off when I'm sleeping so I miss my phone's alarm, which I highly depend on.
Completely unrelated issue but I'm on Sultan's Lollipop ROM and I can't download themes, apps, etc. The device gives me an error saying that the app/theme "failed to install". All of my current apps come from restoring /data from my 4.4.4 daily driver backup. Help with this would be very nice as well.
Thanks a ton in advance for the help.
Fixed! My overclock was too high. I can only assume that it was overheating, causing the freezing and rebooting. Min frequency is at 192 MHz and max is 1512. Stable for the time being.
As far as your reboots go, if it happens after flashing stock 4.1.2 with Odin, then it is hardware. Either the button still, or something else disrupting power momentarily.
Not sure about issue 2 though.
?
