there is a slight curve in my fone that goes vertically with the slide. So when I slide it up, it follows the track of the curve and anything that affects the curve of it, hinders the ability of the fone. I wish I knew how to explain it more clearly. My gf bought me some covers for it from verizon and I tried my damndest to get it right so it wouldn't **** it, but it did and it bent my little hole plug for the charger adapter. Then we took them to the verizon store and 3 diff employees tried to get it, but were unsuccessful. So I just use the sheet on my screen and we is all good.
