[Android Central Question]

I've owned my Samsung galaxy j5 prime nearly a year now, and everything seemed to be fine but not suddenly today it has been playing up . The volume increases wwithoout me doing anything and it makes that really annoying sound as well. I stg I can't fix this. Ive done everything. Restarted, resetted, and even rebooted my phone. Whichseems like a complete waste since absolutely no improvement occurred. Please help. Also none of the side buttons work except for the volume down button. Ugh.
