seems like it :) but i'm checking camera modules to see if there is a diffrence :) your driver is the same as Oppo 5 ,mine is the same as S3 so getting the driver from their individual git and see if it works without too much messing around for m1cha :) but he probly already knows this :)
heres mine :) its from a week old phone
the module i have should be the same as the one on Galaxy s3/ Note 2 :) and the front camera is the same as the one on Optimus G (im not 100% sure)
