Don't use the font camera much but when I tried to use it this past weekend I noticed a defect on the top portion of the screen. This shows up in live view too and the bottom edge of it moves around like a wave length as you move the phone around but stays in that general top portion. I'm wondering if this is hardware or software? Was wondering if anyone ran into this and if a factory reset clears it up before I do it and find out it doesn't. Hoping a factory reset clears it so I don't have to go through a warranty exchange.
