Hello, I replaced a digitizer for a friend of mine and everything seemed fine when I tested before gluing the new digitizer down, but, once I charged and returned the iPad to him and he used it for a couple of days, he is now reporting a couple of issues. He is telling me there are 2 faint blue bars along the top and bottom of the row of icons when he touches the one he wants to open. Also, at times, it will go about just randomly "touching" all over the screen like there is a phantom finger touching all over the screen. He reported he has tried touching the power and home keys until "slide to power off" appears and he powered it off, and then back on without resolving the issue. He really doesn't want to do a recovery or any other steps as he does not thing a simple screen swap could cause an issue like this. Is he right? Are touch screens different enough that it could cause an issue like this where a fresh load could be necessary, or could this simply be a bad digitizer? Supposedly, these are "thoroughly tested" before shipping, and once attached are not returnable for any reason. So, the only way to test is to buy a replacement and attach it, short of doing the other steps of restoring. Is there any way to do a restore for him from another machine without affecting any backup he might have on his computer? Thanks.
