Over and above the not to great design the cover actually by touching the screen start apps or whatever it decides to do. You have to press the right side "sleep" button on phone before closing cover to ensure no weird actions..

The cover is great the only downside is you cant see the notification light blinking. They should of taken this into consideration when designing.

I havent had this long but it brings so much additional functionality to the phone. I just wish the phone would be better protected against drops but I love it.
