There is a major problem with the slider if you open the back of the phone as directed, by pulling the small slit on the bottom of the phone it will destroy the phone's tightness between the top and bottom piece. It will then have a small gap that will move when u tap on the phone. I can't return mine anymore since I am over the 30 days and I have to decide If i want to send it back to HTC to get it fixed...
