So I have a very annoying problem.
Everytime I press power button to lock my screen phone just restarts.
I tried factory reset but no luck.
Problem started when phone got wet.
First it was stuck in a bootloop but somehow I managed to fix that.
But when I fixed bootloop problem, restarting problem started.
I dont have microSD installed or any games, nor I updated anything.
Please help meeee

It really looks like an hardware fault regarding the power button.
I suggest you to contact your seller to have your device replaced under warranty.
