Screen occasionally flickering when waking up phone - Galaxy Note5 Q&A, Help & Troubleshooting

Lately with my AT&T Galaxy Note 5, I have been having a problem with the screen occasionally flickering when waking the phone up after the screen is off for an extended period of time. If the screen doesn't turn on, I have to turn the screen on again with the power button.
I wonder, what do you think might be the problem? Am I correct to assume that this is not a battery problem? My phone is almost two years old (I bought it in May 2016).

My S730 turns off automatically

Hey there.
I have my HTC S730 for nearly 2 months now.
I don't know why but my Wings plays a strange melody and then turns off.
Even if the battery is fully loaded! After it turned off it takes a long time before i can turn it on again. I can push the start button on the top of my smartphone but nothing happens.
I don't know what it is. I Hardresetet my device 3-4 times now but it's still not working correctly.
Can you please help me?
Did anyone recieve the same "error"?
I have the same error!
But no solution.
It happens sometimes, mosty not logical... I'll wait for a few weeks, if it keeps on i'll go back for warranty!
What are you running when the reboot occurs? Never looked but is there a way to schedule it to do such a thing?
Does it display anything on screen before it happens? You might check in the power options to see if its shutting down due to some setting...
When I have some time I will dig through mine and take a look.
Off the top of my head I would surmise that its either overheating and shutting off, an installed application is causing issues and it is turning off, a setting within the phone is causing it to turn off, or something is wrong with the device.
May be caused by overheating. I have no other applikation installed on my Device since i Hardreset it. It shows up the HTC logo when it shutsdown.
I dont run any applications at all. Sometimes i listen to music with the Music Player.
When i start my phone up again (after some waiting time) it shows me that my battery power is 0. After some time of waiting it shows me that my battery is nearly fully loaded.
It only happens 1 or 2 times per day.
But please help me
It's not overheating in my case.
I saw it happen last time (5 minutes ago), just before the HTC logo is saw a little cross trough the battery indicator. I suppose the battery is not good? After reboot the indicator shows a full battery??
I would give HTC a call about those batteries. I would think that they are bad, or the phone is having issues drawing power from them and so it shuts off.
If its overheating it should be VERY warm to the touch, I have gotten mine warm but never hot after some heavy use, but I just let it cool off afterwards and it was just fine.
Usually with low battery it will flash a warning on screen and make a noise indicating low battery, but if the battery suddenly is in zero the phone could automatically shut off. Does it power off quicker than a normal shut down sequence? I would have thought that the phone would just run until it's instantly cut off by a dead battery, but if its misreading it or reads it in the danger zone it could have an auto shut down.
Had the same thing with my wings/s730.
After hard resetting it it worked fine again.

[Q] [hardware hack] i9000 as a timelapse camera

So this is my situation, i have a broken power button on my i9000 and i'm too cheap to replace the motherboard so i have been using it as a paperweight for about 4 months. (i cant turn it on without pluging and unpluging it in my pc for about 5 minutes every time it reboots or shutdowns)
Now i want to use the phone as a timelapse camera, but i want to know if the phone will turn on if the touchscreen and display is disconnected from the motherboard and what are the options of controling the phone via wireless.
The problem is that without the screen being on, the camera shutdowns and the screen is a huge battery drain, even with screen standby it drains out in about 5 hours.
And how long untill the battery goes flat if it is constantly connected to a charger? I need the battery because power outages are frequent where i live.
I would love to hear any suggestions before i start
got it to work, if anybody wants instructions PM me

Screen of death puzzle - s10e

Went to sleep left Exynos S10e just fine. Woke up in the morning to pick up, it was on AOD I could see that it was on (or had some text on the screen at least). Press fingerprint to unlock, no response. Rather odd.
I immediately thought battery was finished. So I plug in to the wall charger, nothing. Phone was not charging at all. Press power, volume, bixby buttons while connected to charger - nothing.
So I left it on charge for 15 mins just for sakes. Come back, same same.
Then I came across a fix for such screen of death on google. While connected to the charger, I press volume down + power for 10 secs. Phone suddenly showed me the charging screen with 78% battery ongoing. It had been off all along (screen of death) as surely it had enough juice but could not wake up.
Since this brief hiccup has already been solved on my part. I would like to know if any other s10 users have previously faced screen of death where phone does not respond to normal action? This seems to be a rare occurrence on here as I cannot seem to find any other posts related to mine.
Thanks,

Random restarts, how to narrow down the cause?

I've had my Note 8 since launch and have been putting up with random restarts every few days (even happened mid call a couple of times) so I took the plunge and factory reset it a week ago. I purposefully only restored the most essential apps to rule out any of them as the cause.
Over the last week, I've had a few restarts and noticed that they occur when the phone is coming in/out of sleep e.g.:
Taking the phone off wireless charge, the screen tries to turn on but it just turns the phone off.
Putting the phone on wireless charge, the phone goes to display the wireless charging indication halo thing then just shuts down.
When I've had a notification come through when I'm out and try to turn the screen on, then it restarts.
These have only happened once each time so I can't repeatedly try any of these out to see if I've found the cause. Has anyone else experienced anything like this or know how to narrow down what the cause could be?
