My iPad is going crazy. It'll randomly open and cycle through any and all running apps by itself. If I kill all the running apps, it'll magically swipe to the left and randomly enter characters in the search field. Sometimes, it'll open my contacts and just cycle through them randomly. I thought it was because I didn't update the OS. But it still happens even after installing the latest OS update. Only way to stop it is if I hard reset it. Powering it down and turning it back on doesn't work. This has been happening for a month or so and at least once a week. Any ideas???
