Something weird is going on with my S8 +

[Matoro]

Okay so when I turn my phone on the volume goes down for some reason and random presses on the screen appear at the top when I am no where near there. I cleaned the screen, I have booted in safe mode, I don't think theres a virus since I scanned with multiple different anti virus apps. (that were free) I think the phone is being controlled by a ghost or there is a hardware problem. Either way I lose, how 2 fix?

Has the phone been dropped or been in the water?

The s8's are nearly waterproof, and yes but a very very minor fall, it landed on a bunch of towels so.

Some water could have seeped in if it was defective and caused it. Moisture could have caused it too

Sadly, phones are only water resistant not water proof like Himommies said "Some water could have seeped in if it was defective and caused it". Moisture could have caused it too"  I suggest you check your warranty and get it repaired/replaced.
