Hi guys, sorry my first post is what is likely to be a stupid question, but I have a question about the screen on my Iconia A500. The touch sensor gridlines that are visible when the screen is off (I've heard this is normal, please correct me if I'm wrong!) are also visible when the screen is black. If I have an app open that has a black background, I can see these lines, and it's quite distracting and unattractive. They aren't visible at any other time; only when the screen is black (like the split second when an app is opening). I was told these lines should disappear when the device is on... so I was just wondering if it's normal? I may be being overly paranoid, this is my first tablet and everything! Thanks for any help Edit: Please guys, just a yes or no answer would be great. Are the lines/squares visible on a black background on your A500 when it's turned on?
