Screen unresponsive (full screen mode with game) - Samsung Galaxy S8 Questions and Answers

I enabled full screen with clash of clans. It didnt like the black bars on the right and left. besides one graphical error, its not too bad. However, recently, the screen becomes unresponsive. hardware buttons work, but screen is unresponsive. it forces a full reboot to get the phone to work..
Has anyone noticed this issue with any other apps? I will move it back to non full screen and see if the problem persists.

G1 touch screen is off

Every once in a while, the touch screen area at the bottom of the screen by the menu bottom is non reactive. for example when i touch n on the vk, it looks as if im touching h. Is anyone else going through this as well?
just recently my touch screen has problem. when i try to switch screen using touch screen, the screen get stuck half way and shaking. and every time the problem occur, i can't make a selection using touch screen. if i select an icon on the top row, an icon on the bottom row is selected instead.
I've had a few issues lie the two above. I'm not quite sure if it's a hardware of software issue, but resetting the device always seems to work just fine. It's not the best solution, but its better than nothing.
have you tried the VK caliberation tool?

[Q] Screen flickering?

After hanging up from a phone call the top left corner of my screen was really bright. There were two vertical lines down the screen and the screen was transparent and flickering. I could still see my home screen and the screen was functional. I restarted the phone and it was still acting up. Only after turning the phone off for a few mins did it stop. Has anyone else experienced this or have any ideas on what would cause it? I haven't had any issues with the phone, no drops or anything. Currently running aokp with matrix kernel.

I had this issue too. My phone just arrived today. In my case the problem occurred after power cycling the phone (trying to get the WiFi to connect.. grrrr) The boot process was fine but once I got to the launcher my screen was flickering like a strobe light. I tried to power off and back on and it still happened. I didn't give it several minutes like you did so I'm not sure if it would have gone away. Since I hadn't really configured the phone yet I simply did a factory reset and it was fine. Seems to be a software issue. I hope it doesn't happen again but if it does I'll see if just leaving it off for a while helps. I hope so because I don't want to have to factory reset all the time!

Nexus 4 (screen)freez sometimes..

Hello,
My Nexus 4 yesterday and today is freezing, when the phone is a little bit hot.
When I open Whats'App, I can't get the keyboard, below it's freezing.
Sometimes it's respondse when I lock and Unlock the phone.
What is this?
I did a clean reset, stock rom, another rom, from the beginnen again, root, TWRP update, but still it's frees when it's a little bit hot.
I have now Euporia ROM.
Also It freez sometimes in TWRP, If i do 3 seconds nothing, than It's frees..
Edit: My Whats'App keyboard, only response when I switch my phone to Horizontal and the screen turns, Then I can open Whats'App. On normale mode (vertical) it's doens't open the keyboard, onle the recorder work's.
It's seems, the screen is not responding in the middle above the navbar..
What Can I do?
Settings/menu works overall.
Could you please test the display by enabling developer options and then enabling "show touches", then run your finger vertically and horizontally across the entire screen to see if it is a hardware issue.

G4 Digitizer problem?

I have a Moto G4 that has had the touch screen become very erratic lately. This issue appeared shortly after a factory reset. The phone is stock, recently OTA updated to NPJ25.93-14.7. It frequently freezes and won't respond to touches of apps or the home/back/recent buttons, and won't side scroll to the next screens properly. Sometimes random apps launch on their own without any touch, and if you try to quit them with the back button they keep relaunching. The problem is intermittent.
I activated "Show Taps" in Developer Options and when the problem is happening there is a tap dot near the lower right side of the screen. It bounces up and down a little bit and vibrates sometimes. When this dot is visible tapping on anything else like app icons or buttons usually has no effect, however the taps are shown on the screen. If I hit the power button to make the screen go black it will sometimes recover when I reopen the display, other times it takes a reboot.
Wondering if it's a hardware issue, a guy at a Verizon store who seemed to know more than most said it was a faulty digitzer--it's seeing touches where there are none. I've replaced displays successfully before, would just like to have a confidence level that the digitzer is really bad before doing that, as opposed to a software or other hardware issue. Any ideas about problems that might cause this problem, like other hardware or a corrupted OTA? Seems very hardware-ish to me, but I'm no expert.
I have Drive links to a couple of short videos on the symptoms, can send links. Much appreciate any insights.
Mine has that issue as well. It will spam the 9 key on the unlock screen or anything in that spot if an app is open or what is on that spot at the home screen. I have to double unlock the phone to fix it. I guess turning the screen on and back off resets it for that session. But it's mostly every time the screen goes dark and comes back up I have to turn the screen off and back on to use the phone.
I had a similar problem and was able to send it in under warranty and get a replacement phone
G4 Digitizer or ghost touch
Apparently this is called Ghost Touch issue, and affects many phones. One solution tried is to disable Battery Optimization for System UI and Google Now Launcher in Settings>Battery>Battery Optimization. That seemed to cure it for a week or so, but the problem returned today. I can sometimes recover form it by hitting the power button to blank the screen and then reopen. Other times it requires a reboot. I see all kinds of alleged solutions out there from dimming the brightness to removing tempered glass protector to using a slow charger, but those don't seem like real fixes but workarounds (if they even work at all). Any other ideas?

Screen flickering

I had flashed LOS 16 and hade been using it for over a year with the same broken display.
Sometime back the phone would just restart by itself and sometimes wouldn't even boot so i had opened the device and found my power button to be jammed. Which i fixed when i turned the device back on started showing this flickering.
Is this a hardware issue where one of the connectors might be causing it or is It the LCD itself?? Can someone explain.

P.S. I also wonder if its LOS itself cause every time after switching on the device the satus bars and all content on the screen would jump up and down but will revert back to normal after locking and unlocking the device
Update
just keeping the screen onwfor few minutes fas eliminated the weird glitches but there still is a slight flicker to the bottom half with lime in the middle
