The main reason why your phone is falling off or not staying on/connected to the SnapMount is that you do not have the magnetic ring applied. Please make sure you are using the magnetic ring that is included in the box. The magnetic ring needs to be stuck onto either your phone or phone case. The closer the ring is to the SnapMount the stronger the hold is. For example, if you are using a really thin case you may choose to stick the ring on the inside of the phone case. If you are using a thick case and not our SnapCase, then we would suggest you stick the ring on the outside of the phone case.
