My Q10 I put in the hand rail of the stairs which is a no no. It slipped off and fell off the stairs. It made me gasp for an air. So I look at it and battery, battery door and phone separated. Put it all back and start it. Thank goodness it is okay. The screen is ok. I really have to start thinking of otter box. I just hate case that makes the phone bulky and hinder my typing.
