360 DEGREE ROTATION MOBILE CAR HOLDER, UNIVERSAL GRAVITY AIR VENT MOUNT CAR HOLDER
This is the best magnetic car air vent phone holder to keep your phone safe in the car. Therefore, the magnetic mount will not have a negative impact. But, if you have some kind of compass on your device that depends on magnetic north/south, there would be a negative impact, but overall magnetic mounting devices are very safe for the latest mobile devices. The location and movement of a magnetic field can influence the sensors to 'see' where north actually is. Inevitably this also means that the electronic compass will be affected by any nearby magnetic field, but the magnetic phone mount/ car vent phone holder won't damage it.
