I removed the sheets on the back and front. The back is now an oily fingerprint collecting mess and the front feels like it's matt and has no Sony logo. It has also affected the loudspeaker of the phone which goes quiet now for over 4 or 5 hours at a time when the phone touches water.
Very bad idea.
Will the front be a fingerprint magnet mess or will it be fine?
Does the glass itself has oleophobic coating or not?
Or remove it and put the screen protector that came with it?
I replaced my LG optimus 2x for this phone and never had any problem with scratches on LG O2X and i never used a screen protector or not even a hard or soft case..
