I have a Verizon iPhone 4S 64gb... Recently, I noticed when I get a text message, regardless of whether it is a text or iMessage, my vibrate alert always doubles up, for a total of 4 sets of vibrations, back to back. It used to be the standard 2. Also, whenever I look at my phone after a while and I see the lock screen, the texts present themselves in a list format, not in the center like a bubble as it used to. I just think this is weird. Anyone have a suggestion on how to fix?
