I appreciate your post. Can you check the display time-out of the phone, just go to Settings > Display > Sleep. Make sure it's not set to 15 seconds. Also, I'd like to confirm, does it only happen with specific apps? I would also suggest if this behavior will occur in safe mode.
To Enable Safe Mode
1. Press and hold the Power button until Power off comes up on the screen.
2. Touch and HOLD Power off on the screen until reboot to safe mode appears.
Let me know the results. Just turn off and on the phone to boot back to normal mode. Thanks.
