Unlocking, but screen does not come on - G2 and Desire Z Q&A, Help & Troubleshooting

I've been having this problem lately since I re-flashed the stock rom on my G2, whenever I press my lock button, sometimes the 4 capacitive buttons at the bottom turn on, but my screen remains black. When I press the lock button again, the screen will flash on and off as if it was on the whole time and the lock button locked it. I usually just have to spam the lock button a few times until it turns on correctly, is anybody else having this problem?
Also, I'm able to press on the unlocking button on the screen and drag it to the other side and I'll have all of the haptic feedback and swipe to different homescreens, I just can't see anything on the screen.
I came from one of the thrown together Desire Z roms and I flashed paul's stock rom, the one with superuser preloaded. I also flashed Cyanogen's addon shortly after the rom. I'm looking for a solution that doesn't require any factory resets, thanks for the help.

Help please, it's getting worse

You aren't the only one with this problem. Are you running an overclocked kernel? It seems like when I run an overclocked kernel I get this problem and when I'm running stock, I don't

Did u flashed back to stock kernel?

How would I flash back to stock kernel? Would I just re flash the stock rom?

same problem with mine, i think it has something to do with the kernel. many people reported watching youtube videos or having youtube open in the back also caused the same problem

Side Power button Stopped working?

Anyone else have this problem? I just got this phone like not even a week ago and it just stopped working. It will work like 10-15% of the time. Should I send it in or what should I do? would it be a software problem Like the rom I installed? I doubt it but I installed the AokP with franco kernal would that be it?
I have aokp 28 with Franco kernel and I've never experienced this problem. If your power button is giving you issues go to settings in rom control and use volume wake with this feature I never use my power button.

1) Flash another ROM. Still broken?
a) No?: It was your ROM
b) Yes?: Go to #2
2) Restore to stock. Still broken?
a) No?: Custom ROMs borked it.
b) Yes?: Go to #3
3) Return the phone / warranty claim.
Had this issue. A little different since it was the volume rocker giving me a headache. Volume up suddenly was hit or miss. Then became totally unusable. Brought it back to the store, showed the problem, went home with a brane new Gnex.

Recent apps bug when waking up screen?

Ive noticed that when my screen goes off and I hit the home button to wake it back up sometimes when it turns back on it shows me the recent apps list as if I held the home button down. Only started happening since latest update. Confirmed happening on stock and frosty jelly bean latest build.. has anyone else noticed this? Btw I have pattern lock as lock screen
Sent from my SGH-T889 using xda app-developers app
Yep - and if you disable the lockscreen it happens pretty much every time. How the home button is handled changed from 4.1.1 to 4.1.2, which is where the issue stems from I believe. It takes a little smali hacking to fix it (though to be fair I would consider the fix that I am trying as being in testing still).
Can you share how to resolve this issue. I don't think T-Mobile has fixed the issue and it is driving me nuts. I don't want a lock screen so that is not a good solution for me. I also prefer not to root at this point.
Thanks for any help!
It requires root unfortunately... though I suppose I could try to throw it into an ODINable tar similar to the prerooted tar thats out there...

I747m screen problem...please help!

Ive searched everywhere and can't seem to find anyone with a solution. Ive found a post with the same problem but no solution.
So yesterday my s3 started having problems waking up. Meaning when I lock it usually you bring up the lock screen by pressing the power button or home button. Problem is when I press either one, screen doesnt come on. The buttons do. If I tap the screen I can hear the ripple effect but the screen doesnt light up. I have to keep locking and unlocking till it finally works. Averege of about 6 tries. When I get a call most of the time the screen doesnt come on either. I can still answer since I know where the slider is. When I do turn it on everything works perfect. No flickering or any other issues. When it boots it works perfect...never fails. Just when I lock it.
I tried restoring already, thinking its a software issue...still does it. What piece of hardware could cause this? I'm stumped. Please any advice would be great.
I'm not rooted and running 4.1.1 oem rogers software.

My guess is that you have something draining all your RAM or being hard on your CPU. When you restored, did you factory reset?
You might have to backup your stuff, factory reset. Test it, if it still does it, bring it up with Rogers for a replacement. If it doesn't, reinstall your stuff until you find the culprit.
You could troubleshoot it also by uninstalling the latest apps you installed.

Like I said...Already did a factory reset. Meaning All apps were gone. Started fresh. Even without going through the first setup (setting up google account etc etc) if I lock the phone its hard to wakeup.
Phone is out of warranty so no go there....
I'm just not understanding what is causing it. I know the screen is fine...buttons are fine...everything points at a software problem. I found a post from a while back where someone was having the same problem....no solution was posted though. I even took the phone apart last night thinking a bad connection or something...disconnected the screen and reconnected it...didn't do anything.
If the screen was going bad wouldn't I have issues all the time? Once I wakeup the phone it works perfect...no flickering or anything. When it boots (which I've done like 30 times between today and yesterday) the screen has come on every single time perfectly fine. Everything tells me it's software related...but after doing a factory reset and running original firmware it seems as though it must be a hardware issue...but which component.
I know the phone wakes up when I press the buttons...I can see the menu and back buttons light up...and if I tap the screen the ripple sound is there...just the screen doesn't wake up....till I try a few more times....very frustrating.
Thanks Again for trying...if anyone has any ideas....greatly appreciated. I'll try and find original Rogers firmware and install with odin...see if that works....

Sounds indeed like software issue. I'm not so sure what would cause it on stock rogers though.
Either way, you can find the stock ROM on sammobile.com or on this thread: http://forum.xda-developers.com/showthread.php?t=1822308
You'll need Odin to flash it. (It doesn't trigger the flash counter)

Did you buy your phone with a credit card? Some cc's have warranty built in. Mine doubles what the manufacturer offers.
Thanks for the link. I will try it tonight and post the results. Really hoping it works.

I downloaded the newest firmware. 4.1.2 official rogers. Problem persists. Must be a hardware issue. Thing is what could cause this? Is it the screen...is it the gpu? I imagine if its gpu the phone is only good for parts as I imagine its part of the motherboard. Oh well...might be getting the s4 sooner then planned.

If you're down for a little test, you could try with a custom ROM.
Use the link I gave you and flash pre-rooted Rogers' ROM. From there, install TWRP (or cwm) using goomanager (from the Play Store) and flash a custom ROM as per their instructions (Don't forget the Gapps).
Before anything though, make a backup
Never know, might save you some time on that S4.

Thanks. I might try it. Dont think I have too much to lose at this point. I always try and keep my phones nice so that when I get a new one I can sell the old one for good money to help offset the cost. This really messes with that system as the phone isn't worth much now...just bought an extended battery too...was planning to keep it for at least another 6 months.
Sent from my SGH-I747M using xda app-developers app
So just a quick update. For no apparent reason the phone started working fine again. It now turns on and off just fine. I'm not going to mess around with it anymore. That's really bizzare. I'll give it a couple days and will report back if it continuous to work fine or if the problem comes back. Thanks for the input.

[Q] lag cm12 flo black screen of death

Well ATM its working.. But lately the lag on my device makes it stutter so bad it freezes up then slowly comes back. Then sometimes the screen goes black and my device won't do anything.. The screen doesn't come back on. I have to hold the power button and sometimes volume buttons together to get it to restart to be usable.
I have only experienced this on 5.0.x roms 4.4.4 never did this
Ideas? Suggestions? Thanks

I've never had those issues on any lollipop ROMs (at least not for this device).
Personally I'm not a big fan of CM, have you tried any other ROMs and/or kernels? Have you flashed a custom kernel or adjusted any kernel settings that could be causing this? Are you using any mods (like Xposed)?
I'd suggest trying out some other ROMs (possibly even just rooted stock) and starting out with a clean flash, with no mods/kernel changes initially, and see if you still have the issue.

I'll give that a try.. I haven't done anything to it because upgraded the bootloader to like 4.04 and installed CM12 on it. It ran so good till like a week or so ago and now its just trash. A case with a magnet for sleep mode wouldn't have anything to do with this would it? But first things first, I'll try a simple 5.0.2 rom and see what happens.
Thanks
