S6 keeps turning off My girlfriend has a Samsung Galaxy S6 that keeps turning itself off randomly multiple times a day (not rebooting). The only way to turn it back on again is to hold down the power and volume buttons. Has anyone else had this problem? Or more importantly has anyone got a solution?
Backup your data
Flash last firmware with Odin
Do not install any app


Check it again if turning off happened again, Its hardware relative and you should send it for repair.

I think flash firmware will fix your issue.
