There could be a few different reasons as to why you may be finding your phone falling off the SnapMount. Please first make sure you are not using a case that is extremely heavy or thick. Please make sure you are using the magnetic ring that is included in the box. For the strongest hold, place the ring on the outside of your phone case or phone, this will ensure direct contact between the ring and the SnapMount.
Another tip is to ensure your SnapMount is secured tightly onto your AirVent. Having a weak foundation is actually very common resulting in a weak hold and your phone falling off. If the vents are not secure enough, please use the adhesive dash piece option. Please watch our Youtube videos on the best placement position for your SnapMount on the AirVents.
