This simple app launch the ZTE Proximity Sensor Calibration Tool on all device without an "official" launcher (like ONDA TIM Tq-150 and probably ZTE Style-q) P.S. i think it's very easy to understand..this app is for ZTE/ONDA mobilephone and/or proximity sensors... NOT FOR LG PHONES :Pplease don't vote "1 star" if you dont' understand what this app is...
