S8+ Screen unresponsive, after several minutes - everything else works - Samsung Galaxy S8 Questions and Answers

Hi,
I am after some help please, preferably without reinstalling all over again (root etc).
If i leave my phone to lock after a few minutes of inactivity, the screen stops responding but everything else works:
All hardware buttons work
AOD - works, I can press notifications and the app opens, or hardpress the bottom home button to get to the home screen, but the screen wont respond after.
Fingerprint scanner - works, it bypasses the lock screen but nothing responds
DEX - phone completely responsive via keyboard and mouse
Soft reset - everything works until it has no activity again.
Safe mode - exactly the same, so seems not to be app related.
Just the screen wont respond after passing AOD but phone otherwise functional. Not dropped, no water damage - all good there.
Anyone gone through similar?
Cheers

Good lock 2018 - lock star
Interesting - after spending nearly all day playing about and deciding to post, i remembered there was a lockstar update for me this morning. I disabled the lock screen i built and the phone has been find since. I'll un-install and re-install it, and re-test should someone else have a problem with it and follow up.

Reinstalling LockStar fixed the problem. Case closed.

Anyone have this issue?
Whenever I have a new rom, it works great, as soon as i reboot or a low battery forces a power down, it is buggy and unresponsive upon reboot.
symptoms include:
1. multiple entries on text/numbers - ie when pressing a, it registers aaaaaaa
2. cannot swipe screen, it will open app on homescreen that it presses
3. overall, no accuracy on touchscreen.
4. overall, it really seems to effect the touchscreen and it consistently happens on reboot.
try calibrating your screen during initial setup or in keyboard settings
touchscreen issue
the only thing that works is to reset data on it from the fastboot screen. (skateboard screen)
From there, the touchscreen works, but i have to start from a new device. Really lame.
Right after the data reset, I turned the phone off and on, and it works. Seems like it only wants to happen after i put things on the device.

Fix for Screen Lock?

As many of us have noticed the screen lock on out Imagio's seems to just stop working. I have had this problem over the last week. I just answered a question in another thread about the screen alignment and how it is randomly activated when the phone is removed from a holster or pocket. In the process I activated the screen alignment, did the alignment procedure and now I see my screen lock is working again! If your screen lock isnt working try aligning your screen and let us know if it corrected the screen lock.
Activate the screen alignment by holding the volume button(up and down) and touch the screen.
Good luck.
Good call Bboyle, I did as you stated and ran the screen alignment and the auto lock started working again. Thanks!
thanks you very much! I had this problem a couple months ago and ended up doing a hard reset and had to reconfigure everything. It worked fine until today the lock randomly stopped working again. Just aligned the screen and now it's back.
Aha! I always wondered how the hell my phone would be on alignment when it was locked and in my pocket.
I didn't know that button combo entered align mode. Obviously it does it even when the screen is locked.
I've never had my phone NOT lock the scree tho.
I got curious when I kept pulling my phone from a holster only to find the alignment utility active. It was very annoying when I needed to make a call but had to align first. So I figured out how I was causing the problem. Discovering the association to the lock was accidental.

Odd rotation behaviour

OK I've had this happen to me for at least three days now and it's finally to the point where I'm posting to see if anyone else has experienced it. I use the Vega in landscape virtually all the time and because of that I lock it in that orientation. However, once or twice an hour the screen will briefly flip to portrait (power button would be on the left in that orientation) then back to landscape. It's very brief and as I said it flips back just as quickly but it's very annoying. It has happened while watching videos too which is more annoying as it takes longer than a browser to change orientation while playing.
I've tried recalibrating it, rebooting the tablet and everything short of reflashing the ROM. I'm really hoping to avoid reflashing to test it as I've finally got the screen calibrated to an almost perfect level thanks to the other calibration app on the MoDaCo forums. Has anyone else had this behaviour before? If so, have you found a fix?
I do not have your exact problem but something similar. Just now I picked mine up and screen was upside down (when the device was right side up i.e. buttons at top and right). I checked the rotation button and it was not locked. When I rotate the device it will not switch rotation at all - when I go into settings and turn off auto-rotation it flips right-side up. It seems like the accelerometer is knackered but it would seem to be working in order to flip it when auto-rotation is switched off. The daft thing is that in various screens it flips to being right side up. It boots up the right way round and the lock screen is the right way round but as soon as unlocked it flips upside down. I too have tried rebooting and all sorts - thinking of flashing it as a last resort.
I seem to have fixed this now. I use quickboot and on a whim rather using my reboot shortcut I used power off. I then used the power button to start up with the rotation lock switched on - when I turned it off once booted it was back to normal. I suspect the rotation switch bit was a red herring - I reckon the shutdown/restart fixed it.
settngs>g sensor>games mode can cause some accelerometer antics try turning on and off
What does the gsensor mode do when activated, as I haven't seen any difference?

2015 Moto X Style - Screen Goes Black w/Onscreen Nav Buttons Showing!

Hi there ...
I've had my Moto X Style for about 6 weeks now & I totally love it ..
BUT, in the last 2 weeks, with no patterns showing, the screen will go black all of a sudden multiple times a day.?
While using an app, the onscreen buttons are there, haptic works on the buttons, black screen, but I have no more app access.?
I can press & hold the power button & shutdown fine. I even cleared the cache' of all my apps using an app, made no difference.?
I'm running out of idea's.?
Falling short of doing a factory reset, does anyone know how to fix this.?
The phone worked perfect for 4 weeks with ALL my apps installed back then,
so I don't know why it's going funny now.? Getting very annoying now, please help!?
On a specific app, or any app?
That's just it, I don't know, coz its random! - But I do take note, but nothing seems to follow any pattern as such.!?
Sent from my Moto X Style!
I have seen this after the phone has been unlocked by trusted device connection with BT and carkit. After disconnect and then trying to unlock the phone with pattern only the on screen buttons are there and no pattern.
Sometimes I tried twisting the phone so it goes in to camera and then swiping to view already taken images. This should give the lock pattern but I also get the black screen with only the buttons. After some retries I get a crash from Nova launcher (message is something like Nova launcher did not respond) after clicking the ok button the unlock pattern is back and I can unlock the phone. Other times this doesn't work, not within the amount of retry's I did, and I have to reboot the phone
Note: When you use the phone right after disconnect, before it's locked again you can use apps, sometimes only active apps, sometimes even start new ones. But after a while it will lock. Probably because it lost connection with the trusted device. After that same problem, can't unlock it again
I Had the same issue after I installed the Microsoft's AppComparison app (I don't know why I installed that app). But a factory reset solve the problem.

Screen wakes up all the time

Hey there,
I've a big issue for a few months already.
My S4 jflte always wakes up whenever the screen turns off.
I tried to figure out where it's caused by and when I cut off the soft buttons (home/menu/back) and started the phone, the screen didn't wake up anymore.
As far as I know there is no way to repair this w/o damaging the screen itself.
So could I block the buttons from waking up the screen?
As you can see when a app is opened and the screen turns off automatically and turns on again, the home screen appears and puts the app in the background.

Could anyone help me? I've been researching for a long time and found no solution.
Says video not found.
Are you on a stock rom?
The Video is working fine for me. Did you copy the whole link and did you remove the brackets? ( )
I'm on AOSP 6.0.1 Kernel 3.4.110-Alucard-PWR-CORE from JDCTeam.
I tried different ROMs so far (including the Stock) and it's definitely a hardware issue.

have you been doing full wipes inbetween roms ? if you have then maybe it's a hardware issue.
Yes, I've always done full wipes. I'm pretty sure it's a hardware issue. Is there any way to block the keys from waking up the phone? I usually use the power button anyways to wake up the phone.
You can probably disable the keys altogether. Or maybe just the menu and back key, and leave only the home button functional.
There is no way to do it with that rom yet, but you could use Xposed and Gravity Box.
Most apps nowadays offer inbuilt menu and back options anyway.
Before you try to disconnect any buttons, try to clean the phone. That has solved many problems in the past.
Look for disassemble S4 videos on youtube, and for cleaning use a small paintbrush, or a very soft toothbrush, and Isoprophyl Alcohol(70% clean alcohol, 30% pure water), you can buy that in the Apotheke.
Clean the board an all other reachable electronics. Let it dry, reassemble and see if it helped.
Thanks for the tips, but I've already done that before (twice) without success.
I'm looking for a way to disable the keys from waking up the screen. I've tried it with the key configuration files in the system, but it didn't work.
Example: When I press the home button the screen wakes up. I just want to disable the wake up for all buttons except for the power button.
Does anyone know a app for this? Or a mod for xposed?
There is no actual "wake up" function assigned to the back and menu key. Only the home button has one. So there's nothing you can disable, except for the keys altogether. I already suggested you how to do that in the 5th reply to this thread.
I've found a work-around. I disabled the keys with 'Xposed Additions' while the screen is turned off or locked.
Thanks alot for your help guys!
