Hey guys I've finally made the upgrade from a first gen ipad to the fourth. Needless to say it was a massive upgrade and I'm really enjoying it. The only problem I have is I'm on my second one. I'm not sure if its just a different design then the first ipad, but the home button is not nearly as responsive. The first ipad 4 I had before I returned it to apple, had a really bad clicky loose feeling to the home button causing it to not work all the time. They gladly noticed the problem and returned no problem. I get home with this new one, button is much quieter, but not so responsive. The more I use it the better it gets, set the ipad down let it sit for twenty minutes and use again, takes a couple clicks sometimes six to ten to wake it up. Sometimes I can push it once, and it mimics a double tapped home button. I've tried the tricks found online, recalibrate the home button, that works well, only for a short time then it begins to get worse. Is this a hardware or software flaw? Am I being to picky, or should I go back for yet a 3rd ipad.
