I've have my S7 Active for approximately 10 days. I noticed almost immediately the screen would turn off if I accidently passed a finger over the proximity sensor if I was using Facebook or playing games. I've rebooted the phone a couple times and it seems to work fine until the first time I play a game or make a call after the reboot. I haven't tried a factory reset yet really don't want to unless absolutely required. Any else had similar problems or any thoughts?
