I've scoured the boards and internet to no avail. My phone is now rooted, it did not use to be. I've had this problem even before I rooted. By checking the proximity sensor with different apps, it does not respond. It keeps a value of 0.0. The light sensor DOES react. The phone goes black and is unresponsive during calls. Nothing will wake it up except plugging in to USB (strangely). Screen On, Keep Screen apps do not work. I've used 'Hardware disable' software and checked the 'capella 3602.0' driver to disable. Still doesnt work. I've also edited the build.prop file and added the line'gsm.proximity.enable=false' and that doesnt work. I'm running android 2.2.2. 'Proximity screen off' app DOES work, it keeps the screen on during calls. BUT it kills my battery in 8 hours - sitting idle. I've disabled all settings in that app that say it will drain battery, but still does. SO- ANY SUGGESTIONS I'm assuming this phones screen was replaced before I bought it, and I'm not good enough to take it apart. I'm looking for a Software work around. Thank you!!!
