I got the proximity sensor to work… Kinda! The first time i installed the st app the screen wouldnt turn off at all, but i installed an app that dimmed the screen down depending on the time. The second time i installed it i got the proximity sensor to turn off the screen every now and then. It does however pick up every movement be either close or acros the room. At night i notice trough my camera that some times its off and some times its on. Its working just not 100%.
