So I just got this phone and everything was working at first but like 3 days later gray flickering lines appears on the screen when I use any camera apps then the phone would shut off. I never dropped it or wet it and somehow this happens. When it shuts off it will do so for like 4-12 times until the warmness cools down. The lines, warmness and shutting down also happens when I put the phone to charge. Also, every time it shuts down the battery percentage drops up to a 10%. Everything else works perfectly with my phone. Any suggestions as to what needs to fix?
If you “just got this phone”, was it bought new or used (pre-owned)? If it is new, I would return it to the place of purchase and ask for a replacement. If it is pre-owned, then you can’t really say for certain if it ever came into contact with water or was repaired. The symptoms you describe sound very much like water damage although it’s not limited to that possibility either.
