It shouldn't be restarting on its own. Try clearing phone cache

Then, if still happening try in safe mode

@Bojkata: Are you using any particular apps when screen gets darker? If you head to Settings > Battery and device care > Battery > Power saving, is this enabled, and is 'Decrease brightness by 10%' toggled on?

No power saving its very strange , hapens on very random situations
