I bought the new r7 and am happy with it in general.
Only one big issue: The ambient light sensor does not work. It always shows me 132 lux. No matter if i am in complete darkness or in direct sunlight.
I tested with various apps and all tell the same: 132 lx
I am on android 6 (Original firmware, came on phone), build 20160720
How to fix this and make the sensor work? i hate it to constantly regulate the screen-brightness manually... On what year are we? 2001 or what?
