Nan but seriously? Why is this so complicated? I've never had so many problems with protection of screens so far yet .... Upscale would mean ultra tedious? The explanations are not particularly clear, and neither the images on record, nor the protection shown in the video on their site matches the model sold. Mention is made of a red tongue .... There are no red tongue .... For 11 euros I had imagined that the grip would have been better studied.
