See, stories like this put a massive dent in the 'amazing value' argument for the 7.
Yes I have had 2, both with problems, first one had screen lift plus when you touched the bottom left of screen it looked like when you press an LCD with your finger, the second one has an auto brightness problem that completely blanks the screen so you can't see anything, if you put the brightness slider down to the last 3rd the screen goes off completely, not very good QC.
