Why does my galaxy s7 sm-g930u not able to switch light and use camera

[Johnzine]

The camera app gives this warning "camera fail"

The light also gives this warning " camera light is been used by another app

No network too

I have booted Into safe mode but the same issue persist.

I disconnected the camera flex cables but still the same issues

The motherboard also becomes very hot when switched on

I have done factory reset

I have flashed firmware
But still

Any help please

Welcome to Android Central! Since it persists in Safe Mode, and since the motherboard gets really hot, then I suspect hardware failure. You'd have to bring it to a repair shop, but that phone is likely not worth spending the money to fix, considering how old it is.
