Black screen after restarting - Samsung Galaxy A6 Questions & Answers

My phone was freezing all of a sudden and I couldn't get any audio from any app so I decided to reboot the phone. As it's rebooting the screen went black and I couldn't turn it on. I've tried Power + Vol Down for 7 seconds and it's not working. Phone I'm using is stock rom A605F.

[Q] Ativ S stops loading on WP logo

My Ativ S (i8750) ran out of battery, so I plugged it into a charger and waited. It powered up normally by itself, but stopped loading on the WP logo and just displayed it for a few hours (while still being charged).
Holding the power button resulted in restart, but it still stopped loading on the Windows logo. The only way to turn it down was to remove battery, and each time it refused to boot up into system.
The only things that still work on it:
-power and volume up: brings up the bolt icon,
-power and vol up + camera opens downloading mode,
-power and vol down (exclamation mark) worked only once after each rom flashing, but hard resetting wasn't possible due to the screen completly turning off (during key-combination; not answering for hours).
I was using this phone for a month before this, with official 8.1.1 done over OTA.
Since the downloading mode was working - I flashed it with the GDR3 CMJ1 rom. Everything went smoothly, but after the restart it greeted me with the same issue: stuck at windows phone logo (now with the older gdr3's look). Flashing it again, or with the gdr2 bme1 doesn't change anything.
What can I do to bring it back to life?

Phone touch screen not working and phone won't turn off

Hi everybody,
So I have an HTC One M7 running Google Play Edition Rom and my touch screen stopped working. Now, this isn't the first time it has happened but it is the first time it's happened on this rom. I was previously running Android Revolution HD and when my touch screen stopped working, I would hard reset by pressing and holding the power and volume down button until the buttons started blinking for around 10 seconds, and then the phone would restart. However, I can't hard reset my phone anymore. I tried holding the power and volume down button down, but after a full minute, the phone still didn't restart; it was just the capacitive buttons flashing. I tried every combination of holding down buttons but it still doesn't work. What should I do? Any help would be appreciated.
use an OTG cable adapter and plug a mouse ;
go to settings backup and reset : reset phone .
if this is what you want to do.
kinda only way to reboot if you stuck .
or download a rebooter apk

My Nokia 7 Plus does not boot at all or stuck on Android One logo

My phone suddenly restarted and stuck on Android One logo and not booting further. I've turned the phone off and started after few seconds and it was still stuck on Android one logo. Then I've tried to get into recovery mode by pressing Vol Up + Power but it was not working. Also it's not responding to the charger. No battery sign and nothing. It does not respond to power button many times. I've also tried to get into fastboot mode (Vol down + Power) and even it was not working. Please help!
It's not rooted and didn't try to flash/install custom ROM.

Take phone to discharge batttery and automatically turn off. Plug in to charger for few minutes and press and hold volume up,volume down and power for 2/3 minutes. He should be turn off and then you can go in to recovery.
Suffering the same problem.
I'm having the same problem. Exactly what you said. I didn't root my device or even attempt to do anything. I bought Nokia because they were purely stock and delivered some quality mobile phones. I've got only this phone as my daily driver. So tell me if you have got the issue fixed and how much did it cost and how long it took. It's been stuck with that 'android one' logo and a small message that reads 'Download mode' on top. I've tried everything. And what I'm worried about is, my phone's out of warranty and I'm a student. I hope you got it fixed for some reasonable cost. Please reply to me ASAP.

S10e no download mode, no TWRP, strange Black Screen / Brick Issue?

After i tried to solve another issue with a custom Rom and installed a TWRP for Hades Rom, my S10e doesn't start normal, download mode also doesn't work.
Only thing is, if I press Power + Bixby and Vol down, it vibrates and the Samsung logo appears shortly.
After that the PC (if USB is connected) shows the folders but display of the phone is still black.
Funnily i can tab on the phone screen and it vibrates on some areas, so I assume it is in TWRP but with a black display.
I'm completely stuck now, searched a few hours on google and XDA for a solution but nothing works.
Power and Vol down mages a restart, if USB is connected the folder appears after a fw seconds on the PC, Display still black. When i tab on the phone it vibrates but no display, so no idea what i'm doing.
Download mode or "visible" TWP doesn't work, tried also several button combinations, nothing works.
So, how can i get in download mode to do a reflash? I've no data on the phone so wiping is no problem. Any ideas?
Edit 1: It seems i could solve the issue by draining the battery completely and go into download mode afterwards, so - solved for now
Bump, having the same issue
Hold power and volume down to get out the black screen

phone frozen and power button + volume up does not work.

Hi,
I am on Lineage OS 17.1 and my phone frozen while using the Anki app. I got an error message about loading fonts then the phone froze, blank screen and it is completely unresponsive. Power button + Volume up does not reboot the phone, plugging it into USB seems to do nothing.
Is there any other way to restart the phone?
