10 x mumbi Screen Protector Samsung Galaxy S3 protective film (deliberately smaller than the display, since this is domed) (Wireless Phone Accessory) 1
It will come in three different sizes protectors. Only the smallest film fits halfway, but not at the recesses above and below. Because it is too long and it formed small edges which rest not clean on the display. Since the S3 display bulges at the edges and the two recesses above and below, must be a certain distance between the film and said problem areas exist. Only in this way, the film is to clean. Less is more in this case!
