This has been happening on my iPad Mini only, not my iPhone 5, both of with has beta 2 and beta 3 installed. Again, only on my iPad Mini. When I double tap the home button to activate multi-tasking, switch control will automatically turn on! It's very frustrating because switch control is VERY tedious if you don't have accessibility issues. Has anyone found a fix for this? Do I have a setting turned on that's doing this? Feedback would be great.
