So I've noticed this for the last couple of days and haven't been able to find anyone anywhere on the internet that has a matching story. Maybe someone can help me: Every now and then, when I double click my home button to open the multitasking bar at the bottom, it only registers a single click. So if I'm on a screen other than home, I double click, and it takes me to home. Here's where it gets weird though. Sometimes it's like it saves the extra click so the next time I single click, it takes it as two clicks. This is such an annoying issue. I have a feeling (and I hope) that it's software related. I have already had to make several exchanges, and if this ended up being a hardware problem, I would be very angry. I know Apple would take care of it, but I'm really sick of going back to the Apple store. Anyone had this problem or something similar?
