Hello, the proximity sensor to my Red Rice no longer functioning properly. Or have failed, or is not calibrated. Ever tried using the PlayStore applications to try calibrating but not got results. Also googled and not got results. Even tried to see if MobileUncleTools application if there was any option that would allow to calibrate the sensor. But have not seen anything that could help. Do not know what else to do Someone can help me calibrate the proximity sensor? If I can not calibrate, will have to go to the warranty. Thank you!
