Reboot phone = black screen until hard reboots like 2 times - ONE Q&A, Help & Troubleshooting

My phone when switched off and switched back on sometimes doesnt show a screen, it shows the boot up animation but then if i dont use the phone for like 5 mins after boot it would just stay with a black screen until i reboot and use the phone straight away, its a weird bug.

[Q] Android L 5.01 lock screen reboot

I have a single issue when the phone goes to "sleep" mode it reboots.
so i set the lock screen time out to 30 minutes, sure enough phone is stable and useable, if i set the phone down for 30 mins as soon as the screen goes dark, it will reboot
same as if i turn it on, when its on the lock screen after booting, if i dont touch it for a few seconds as soon as the screen goes dark, it will reboot. this is now my ONLY issue
is this a known issue? i cant find anything for a fix for it. help is appreciated.

[Completed] [Q] Moto G (U.S Cellular) boot loop. wont charge.

ok so i have a moto g that is fully stock and all my apps were from the playstore and i never noticed any bad lag at all. but one day, out of the blue, i wake up to my phone showing the blue m logo and then a black screen and repeat.
so i tinkered around with it and searched the internet and heres what i found out:
I can get into fastboot mode but cant use any tools except for the barcode tool otherwise the phone just goes back into its boot loop. (yes i selected with the volume up key)
the phone has no power what so ever unless its plugged in. and i dont have to press anything to start the loop, it starts on its own as soon as i plug it in. the led blinks white twice and shows the m logo for about 5 seconds then a black screen and repeats once more then it is black for about 5 minutes then its goes into the loop once more.
i cant flash the stock firmware because when i plug the phone into my computer and put it in fastboot mode, the fastboot menu pops up for a mere seconds then the screen goes black and goes into the loop again.
the phone is not damaged and worked with no problems a few days back. i have been through countless websites!
any ideas?
Hi,
Can you specify if it's a 2013 or 2014 moto X.... And I will have your thread moved to your device Q&A section.
Sounds like a stuck power button to me though.
Thanks!

Nexus 5 Problems

MY nexus since this morning started to reboot randomly.
When it starts, it keeps rebooting at the google logo (not the animation), sometime it can go past it, going into android with the shut down option displayed, but after 3 seconds it reboots itself.
Sometimes it happen that when it enters android, it will optimize apps , enter android, and then reboot again.
It will do even on the recovery. (wanted to try with a reflash/wipe/etcetc)
What do you think guys? Battery problem? power button malfunction?
Should I sent it to google and hope they do not charge me anything?

HS-U939 white fuzzy screen after flashing wrong rom.

Hi.
My HS-U939 became very slow and unresponsive so I decided to re flash it. I used SP flashing tool. After it were done my phone only shown a white fuzzy screen with lines and faint dots and keep rebooting to the same white screen. I have tried everything but nothing works. My PC wont detect my phone so I can re flash it. The only time my I can see on my screen is when I hold power - & power button. I then get Select boot mode. When I choose recovery the phone restarts to white screen but still don't detect on PC. If chosen fast boot it detects for about 3 seconds and then disappears. When I try booting without battery the device detect and undetected every second. Is it possible to fix this or can I throw the phone away?? Thanks.

Pixel issues

I don't know if it is bad hardware or what but the issue first started when I was sending a text and my phone crashed. It then would boot into the google icon and reset doing that as a bootloop. I put the phone aside for a bit and then tried restarting it the phone would start but after 5 min of use would freeze then crash. It keep starting up fully then crashing after 5 min. After a few times of that it went back into the bootloop of just the google logo on the white screen.
I also will see like fuzzy lines over the screen sometimes before the phone crashes, any advice?

You can contact Google pixel help as long as it's not in beta.
Have you tried holding power down about 7-10 seconds and while hold down power for those seconds, hold down vol up and then release vol up, then power. Should put you in a screen with options.
