Back,Recents button and touchscreen randomly stop working. Samsung Note 5

[Android Central Question]

Hello looking for help with Samsung Note 5. When i am using an app such as Chrome or Youtube my Back, Recents button and touchscreen all freeze up. It usually lasts about 5-10 seconds or instantly fixed with turn off and on. My phone has never been dropped and has the latest software upgrades. I have also restarted my phone and the problem persists
