Tablet screen randomly turning off and on after I shut screen off - Android Q&A, Help & Troubleshooting

Hello I recently did a factory reset on my tablet and now everytime I shut the screen off I see it turn back on for a couple seconds and then turn back off again then about 20 seconds later it turns on again and then turns off and it keeps doing the same thing over and over again and I have no idea why. I tried restarting the tablet, and the problem is still the same. If someone could please tell me how to fix this issue I would greatly appreciate it. Thanks in advance!

Phone turning off by itself

My phone keeps turning off by itself every 20 or so minutes. All it needs is turning on no reset or anything.
Any solution.
Please help.

Screen won't turn off automatically

Having a problem with the screen not turning off whether it's set on a timer or smart stay. The strange part is it is only when I turn off Wi-Fi power save to keep from getting booted from my network. When I reboot my phone, screen turns off fine. As soon as I turn off Wi-Fi power save, the screen just stays on unless I got the power button. Anyone else experiencing this issue or know a workaround?

[Q] Alcatel 995a Issue

Hey guys,
I was using my Alcatel OT 995 last night, then all of a sudden it just turned off, now I wasn't really surprised as this happens a lot. But the real issue I am having is that I can't turn it back on. I try and nothing happens. I connect to a Charger and the notification LED, Back key and Menu key all flash. Then after about 3 minutes they stop.
I guess the main thing I am asking is has anyone had this issue? And how do I fix it?

Screen turning black and won't respond

after exchanging my phone due to the reboot problem, im encountering a new problem
my screen sometimes turns on by itself, and if i try to operate it at that point, the screen will turn black and nothing is functional except for the soft buttons and the pull down menu, only restart will solve this
sometimes it will also just crash to black even without the screen turning on by itself scenario
does anyone have the same issue? i suspect this is a software problem
I just got the z5 last night, and experienced the same problem this morning. Turns out that if you give the power button a 'double click', the screen comes back on. So this solves the problem reported above.
HOWEVER, there must be a setting (I hope) which we can change, I find it very irritating that as soon as I make a call, the screen goes blank, and you have to double-click the power button to see what is happening. If anyone knows about such a setting, please let us know!
My screen went black about an hour ago.
After Hotspotting for 40ish minutes so I could use my iPhone on the way to work on the train, I tried to check this forum with my Z5C, the back of it was really hot & after a few minutes, the screen went black & the phone was unresponsive for around 20 seconds & then basically unusable once it came back on, for another 20ish seconds, due to lag.

Did you ever find a resolution for this? it is driving me crazy, I've tried factory resets, software repairs via the Sony Companion and this still occurs, sometimes it won't happen for a week then sometimes it happens multiple times in a row even straight after a reboot. The fix that RohitMayor describes does not work on my device. This phone is really terrible compared to the Z3 Compact
I have the same issue. This pb occurs since i have update my phone to 6.0.1...
Any solution ?
