[Q] turning screen off crashes phone

I have the strangest damn problem on my phone. Sometimes, when I press the power button to turn the screen off, the phone just shuts down completely and then when I try to reboot won't get past my splash screen. When this first happened I couldn't get the phone restarted at all, even by taking the battery out and waiting for over 10 minutes. Everytime I tried booting it would go to the splash screen and then blank back off. It would do this once and then I had to remove and replace the battery just to get it to boot to the splash screen again. I thought this might have something to do with having a custom rom installed (sacs custom), so I played around with the phone and managed to get it in Odin mode. I then brought the phone back to stock. Everything worked so I figured I had fixed it, but then after pressing the power button one time I got back the same problem. It shutdown and would not restart past the splash screen. In retrospect, I think when I pressed the power button the screen did not immediately go off and so I clicked it a couple times in a row before it crashed, that may be what triggers it, b/c sometimes i press the power/screen button and it goes off without incident.
So, now I had the phone back to stock and had the same problem. It turned off and would not boot past the splash screen. By a stroke of good fortune I figured out how to get the phone booting again past the splash screen. When the splash screen came up, I started repeatedly touching and swiping at the phone; drawing little circles tapping at it, etc... When I did this the phone continued to load and boot up normally.
I installed AVG antivirus, to see if maybe there was malware on my phone. Scans showed nothing. I updated all of the software as well. I now have an app installed for turning off the phone instead of using the power button. This of course is not an ideal situtation, why should pressing the power button crash my phone like this??

Phone vibrates but wont show screen?

So after i had sucessfuly rooted my galaxy, unlocked the bootloader and installed cm13 2-3 hrs later cm 13, starts to turn off the screen but stays working since i had it connected to pc and i was able to move files back and forth... now since i couldnt get it to stay working i decided to restore using twrp but after slidingto confirm the restore the phone immediately shuttled its self down, so i decided to flash stock rom which it did flash but with screen off while odin was doing its thing.... now when i turn it on i can hear sound but no image and for the screen to work i have to connected it to a power sourse first then turn it on but stays stuck on verizon screen loading!! so i flashed stock rom again but again same thing!! EDIT now afer it went past verizon screen it said set up wizard stopped working.... i have flashed stock rom like 5 times now..
Current status of phone: phone will turn on sometimes with visuals but most of the time you can listen to it booting with no visuals untill it reaches verizon and just hangs there, last time booted some kind of accecibility feature that telling me what the phone was doing at all times, just right after the verizon logo saying " set up wizard stopped working"
- i can access download mode and recovery mode sometimes with screen working and other times without it working so i might just be soft bricked maybe bootloader brick?

This actually worked and booted the phone thanks man... however i dropped the phone and now when the screen do turns on but after couple of minets of usage like 3 minets the screen shuts off but the phone stays fully working, does this means that replacing the LCD will fix this? or maybe something inside is loose as a result of the drop?
Edit: actually after screen shuts down and i leave alone the phone shuts down completely and restarts when i attempt to push power or home buttons and after it restarts the screen is not visible anymore... so to get the screen to show again i have to remove the battery and wait couple of minets to put back on and sometimes this gets the screen to show but some times it doesn't... if i remove the battery and immediately put it back on this wont work i should mention

Try opening it up with a heat gun and checking for loose connections.

OnePlus 5 Bootloop after factory reset!!!

Hi Community,
I had to reset my oneplus 5 because of a annoying adware that i might have got from something was experiencing ad pop ups even on the home screen. So i did a factory reset from setting. My phone restarted and the boot screen appeared. After one or two mins both white dots of bootlogo merged and big red logo appeared (device was about to go to setup page) but instead of going to setup screen a black screen appeared and again bootlogo started rolling... i thought its a reset process but it just on for a long time, around 20 mins. So i restarted the device by holding power button and phone restarted to the setup screen in no time.
I again did a reset and same thing happened
Can some please tell me was that normal or was a bootloop??
Please help

Stuck in Recovery after messing with Simulate Secondary Display

Hi everyone! So I'm pretty stupid and I was messing around with the developer options (even though I knew I shouldn't). I clicked Simulate Secondary Display and chose one of the options (not sure which one) and right after the screen went all black, I got scared and tried to reset it but for some reason it went into Recovery. I tried the "Reboot to System" option like 50 times and this is what happens: Most of the times it just goes back to the Recovery Main Menu, but some times for some reason it seems like the phone starts normally (still black screen tho) and I can manage to start the camera (by pressing - volume 2 times) and I can actually take pictures! Only for a few minutes because then it restarts itself again and I'm back at the Recovery Menu. Tried Fastbooting (even idk what it is) but it just stays on the fastboot screen with the russian bunny trying to fix the Android robot?? PLEASE HELP!! :crying:
