Phone doing things by itself

Whenever I listen to music, watch a video or sometimes even text my phone will randomly start changing the volume or open my Bixby without me touching the phone. Sometimes il close spotify to try and fix it and before I reopen the app itll start playing a random song from my playlist. I’ve seen videos of people cleaning there screen and restarting the phone multiple times. I’ve tried everything and dont know what to do any help?
I have a s9 that I bought used a couple months ago and it just started doing this a week or two ago
