Last night, I decided to check out some of the new roms out for the droid 4 so I downloaded the avatar rom and tried it out. It worked fine except when I would lock my phone and put it into sleep mode, it wouldn't always wake up the screen when pressing the power button. The lights for the hard keys lit up, but not the screen. Then sometimes the screen would light up, but the touch screen wouldn't be active so I couldn't swipe to unlock. It usually takes between 5-10 tries until it finally works. I had the same problem with the AOKP rom as well.
I thought it might be the performance controls keeping the CPU too low when the screen was off and therefore having trouble waking it up so I set the minimum to 600 but that didn't help. Any ideas?
Also, slightly unrelated question but is there a way to turn off the transition animations for 4.2.2? I can't seem to find it :/

I have had similar issues with the 4.2.2 ROMs although not as often as you. It would happen to me maybe once a week. I would just hard reboot the phone when it happened. Not sure if it's an issue with the kexec kernel or what.
As for the transition animations I would assume they would be in the launcher settings somewhere.
Hi!
I've installed the CM 12.1 by downloading and following the instructions from the CM wiki page for Moto G 2014, and also by reading threads from XDA. Now I've been using this for the last 2 weeks and this is happening once after every 3-4 calls. Whenever I get a call the whole screen turns black and doesn't respond :/
I've a LG G Watch as my android wear, so I use that to receive the call. After the call gets over, the screen is still unresponsive and I've to restart the phone by holding the power button.
I'm updated to the latest nightly. How do I solve this issue? Any help is appreciated.
Thank you.
This dead screen issue is still not fixed. The screen still dies after a few days of use. And it feels like the backlight of the screen turns off because all of the features of the phone still work. I've to restart the phone to turn the screen on again.
I'm updated to the latest nightly. Any fix for this issue? PLEASE HELP.
Try different ROM remember clean flash
I might have the same problem. I can see the phone is recognized by the computer and the adb command "adb devices" shows it. I also hear the sounds produced by raising the volume buttons. Rebooting it won't bring the screen on. Any idea how to fix it?
EDIT: I Noticed that flashing strong light on it shows the screen a bit. Managed to turn of the live display option and crank the brightness setting to the max like many suggested. No change. Also updated ROM to latest CM12.1 (20150831) tried flashing a strong light into the front camera/sensor and using adb to set the brightness to 200. Still no change
The odd thing that makes me 90% certain this is some kind of hardware failure is that the dark screen persists on recovery and bootloader screens, not just system.
I have same issue, screen not waken up when call comes but just pressing power button shows screen for me
I've had this problem with 2 different roms now (PureNexus, Chroma) on a few kernels (stock, ElementalX) so I'm not sure whats causing it but I need a fix. In a call, many times the screen just stops responding. Sometimes I can turn the screen on/off using power button and its fixed. Other times nothing works and I have to do a hard reboot by holding down power key since nothing else works on screen.
This is on latest version of the rom/kernels. Any ideas?
When you say its stops responding, do you mean it goes dark and nothing displays on screen? Or that its on with everything displaying but tapping it does nothing?
Only when in contact with ears?

Its on, touch doesn't do anything. The phone is working since volume keys bring up the UI but you can't do anything. Also proximity sensor works, it turns on/off as I bring near ear. I don't have a screen protector.

I'm having a similar issue from the last month.. I'm on DP5
when i get a call most times the screen is off.
To answer the call i've to put on the screen, unlock the phone and then go to the heads up notification and choose answer there..
waiting for nougat final hoping it'll fix this.
Tried fiddling around with notifications importance setting.. it helped a little but then there was the annoying heads up showing along with the regular incoming call screen.
Sometimes (very rarely, has happened twice) the screen just remains black and will only work normally after a reboot.
Anybody have any suggestions?
I was having similar issues, also on the Developer Preview and I ended up noticing that the phone app was blocked from showing any notifications despite the fact that I never set it that way. I would hear the call ringing but would never see the screen to answer. Just changed that setting and everything was back to normal. Perhaps something is causing the phone app to fail to show notifications for you as well.
Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

Yeah that sucks, i can imagine..... i too hate the idea of refurbished units being swapped for warranty....bs, should be brand new unit!
Sent from my God Mode 8
so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.
After upgrading to Lineage OS 15.1, I realize that if I have screen lock set to pattern, then it is extremely hard to unlock when the screen has been off for a while. The screen will stay black while when I'm holding power button the phone will vibrate as if I'm calling power menu. This black screen can last at least one minute. I also set long press to open flashlight when screen is off and that doesn't work. Those symptoms makes me believe that the phone is awake, yet for some reason can't get GUI rendering. Sometimes even when I enter the correct pattern and the animation moves dots and timer away, I can still draw unlock pattern on the hiding unlock dots, and phone will vibrate in a very laggy manner.
Currently I'm running with no screen lock as even "swipe" still cause the unlock process to be very painful. Is this a known issue for LOS or is there a way to fix it? I saw a post says the battery should be replaced if phone is laggy. Is that a possible cause?

This isn't a known problem.
From what did you upgrade?
Which build are you using?
Did you do a clean install?
Which gapps are you using.
Do you have Expanded Desktop enabled?

I was using Stock Android before, but I fully wiped everything before I install.
15.1-20180508-NIGHTLY-shamu
Yes.
I got my GApps from Open GApps, but didn't remember which variant but most likely nano.
I actually have this enabled. I'm gonna disable it and see how that works.
After turning off Expanded Desktop the issue seems to be gone. Though when turned on again after some times the lag is still somewhat exist.
there's a Xposed module fix for this http://repo.xposed.info/module/fr.merams.r.deepscreenoreo
