Easily one tends to press the on / off button when placed in the holster Z10 (so if it turns back off.) And those of the volume when it is removed.

Small drawback of the magnet of BBerry Cases: beware of hotel keys demagnetize easily from them. Fortunately credit cards are generally less sensitive.
