Just got my device yesterday.

 
I also wrote for the book cover-related problem down below.
So when I lock and leave my device for a few minutes or hours, when I try to open and start using it again, it seems like it automatically turned off. The screen would not start or react by clicking the power button or tap the screen twice.
 
In this case, holding the power button would not work as well, just a force reboot ( power button + volume down) would work to get it restarted.
It happens even I entered safe mode.
Could I get help?
 
+ I disabled the book cover accessories setting.

Try the power button and volume up (when the device is off) this puts the device in recovery mode

In recovery mode look for the download feature

Hook it up to your computer via Kies or SmartSwitch and download firmware to it

I just got s7 tablet and am using third party book cover that has magnets for the hall sensor.

when I close the cover and try to open it again, It should automatically turn on itself, but instead it freezes with black display and dies out. 

Even if I push the power button it does not response. it only comes back when I do the force-restart with power + volume down button.

The hall sensors do not seem like it has a problem since it passes the hall ic test when I did sensor test, but still it is problematic.

I have the software up-to-date.

Can you help me?
