http://androidforums.com – Hello I'm running CM10.1 (unofficial) on HTC One X, endeavoru I flashed a .zip of android 4.2 photosphere camera, and it works great except..you can't use the front facing camera for pictures, only for video recording. Which is pretty weird Anyway is there any way for me to 'unflash' that camera a without losing my current ROM/settings? Thanks (General)
