Hi Bojornar Skaar, Something that I have tried many times at my workshop which has fixed this issue is (as crazy as it sounds) going into settings and reseting the network settings. The reason for this is because the proximity sensor is a part of that circuitry. Another suggestion is checking for dust under the sensor because that can stop if from functioning. If you have any question feel free to ask! Best Of Luck!!!
