Tested on Galaxy S3 4G & classic, walking for two Used for one month, "normal" use, jean pocket or just on the desk, not jaded yet All functions (flash, photo, ..) are available No scratch on the screen, but I have not put in the pockets, so check on that, but I do not think it moves enough to scratch anything. Relatively easy to remove if necessary
The only problem is that when we want to call this cover is not very practical, it is necessary to fold the leather to hold the camera correctly, and suddenly I'm afraid it the abyss in the long run.
