it happened randomly
but when i use it whole day without stopping, i never encounter this issue, but when i stop using it for few hrs because of work it happened
what do i do?

been using this phone for almost 3years
accidentally dropped it on head, knee and couch level for a few times

Then all you need do is buy an identical phone sold for parts with good socket and have that person swap them over. Actually it might even be a board swap if not too fiddly, no soldering required.

If your phone lags or drain too much battery, it has a feature called "Auto Boost at Screen on" that'll fix it. My friend's Samsung had both of those problems and this app made that phone useable again.
I suggest turning off other options in its settings so you don't get pop ups for cleaning.

The camera app switch off after a few mins of use due to heat. Is there a way around this problem?

Generally a nice phone, the only glitch is the camera doesn't start sometimes, prompt error.
