Hi @Sammy_Gawigawen_Este, sorry to hear that. I understand that the images taken from the front-facing camera appears grainy on v3.6. I am sure our Developers are doing something about that so hang on tight.
Otherwise, you may try to look for the full v3.2 firmware and perform the manual flashing via SD Card. You can find a tutorial on how to do Manual Flashing here.
Please note that I am not 100% it will work so Flash at your own risk.
