Why does my s7 reload pages automatically and seem to jump around in apps?

[Android Central Question]

If im in a brower window, the window acts like i hit a reload/refresh button then takes me right back to where i was before (like scrolls down to where i was reading in an article.)

It happens in FB app, Netflix (skips bavk 5 minutes... plays for 30 seconds, goes back to where it was originally, over and over), Chrome, games (can't play them cuz it takes me back to start)

Phone is generally chunky perdormance too. Reboots on its own every day randomly.

Help!

You’re sure it’s a genuine S7?
