S6 Edge sensors go crazy ...

Have anyone an idea for my problem :

I have a S6 Edge (german version g925f) and my IR Blaster does not work , even without gps . yes i said gps.
My other sensors like Proximity , Heartrate , all axis sensors (acceleration etc) START working everytime when i (really get, just activating is not enough) really get GPS signal , these start working .

i did several hard resets ..
loaded older stock firmware

but still no working ir blaster and the gps need problem...

what do you think ? (i have read that the fast charging kills the sensors etc. ) i am still using it its useful...
