My phone keeps tapping on its own

[AC Question]

So far I've tried reformatting my phone for so many times now.
I've tried cleaning it with alcohol.
And I've also tried letting it be on its own for awhile hoping it will just disappear.
But it still won't stop.
It's already to the point that i cant use it anymore since everytime i open it, it starts clicking and opening apps i'm not even trying to open
And when i try to write messages, it will continuously keep on typing on letters and won't stop.

Sounds like your phone is possessed. What phone do you have, has it received any physical or water damage?
