PLEASE HELP URGENT

[Reyad]

I have a Z1 compact and I decided to take some videos underwater little did I know a few hours later it shut off and had a vibration pattern like - --- I charged it and started it up but then it started turning on and off so after that issue was fixed a black dot in the corner appeared and now it's expanding to huge extents another issue is that the camera opens at random and I have to force restart to get the phone to turn on from wake mode I can lock but not unlock

Did you let the phone dry properly after using it in water? And did you make sure all the ports were sealed securely before submerging the phone?

[Reyad]

I triple checked all ports closed and it fully dried

I would suggest contacting Sony Xperia support and inquire about their vacuum test and see if water may have entered into the phone and if so what they can to fix that.
