Been reading all these posts, and I'm experiencing the same issues, but they just starting occurring today (as far as I know). I've had a invisishield screen protector and a simple case, but I've had these for a while without issues. I cleaned my screen, didn't help. Rebooted, didn't help. Closed all the apps and rebooted, didn't help. Everything else has been consistently the same (same chargers, same daily average usage, etc. Haven't downloaded any new apps recently. I doubt this is related, but I do use Good apps (it's for work, but like I said, that's probably not the cause).
The only thing that changed was last night, when I was renaming the hand-me-down MacBook Air my wife gave me, and then trying to get the iMessage app to sync with my iPhone and iPad. Since I renamed the MacBook, I had to reset my iCloud password so everything would appear properly. I had a time troubleshooting, but finally got it all working.
This morning, as I started working and using my iPhone, I saw the same problem as everyone else. Seems like it typically opens up the camera app, although sometimes it decides to open up my contacts or some other app. Oh, and typing an email is almost not possible. This is bad...very bad.
HELP!!
