Help Phone keeps restarting

[Fahadi18]

Hello everyone

I'm having problem with my android phone since last night. It keeps restarting by itself. It all started when my 6 year old cousin restarted my phone continuously for like 6 or 8 times in my absence for course. Otherwise I would have been in jail by now. Lol
Please help. Thanks in advance
Edit: just found out that my camera is also not working. I get an error saying " Can't connect to camera"

I suggest you bring it to the store. This is not normal.

Go into your settings and perform a factory data reset. The exact settings location varies by model, check storage.

Do not elect to erase all storage or you'll lose your pictures and videos.

You will lose your data and apps and have to reinstall them.

Thanks for your responses guys. I cleared all my junk files and cache using Clean Master and it has been stable since then. I had installed WWE 2k game 2 or 3 days ago, Could that have caused this problem? It worked fine until yesterday. And like I said before it started when my cousin messed it up. But the confusing part is how cleaning cache and junk files solved this problem? I don't see any connection. Isn't it weird?

Will see if it works fine for next 24 hours and will post back the results. And again thanks for the tips.
