If the magnetic attraction is not strong enough when the metal sheet is
between the phone and the case, we suggest using a thinner phone
case or put it outside for direct contact with the magnet.
Adjusting the Viewing Angle
We suggest adjusting the holder to an appropriate viewing angle
before mounting it on your car’s air vent blade. To adjust the viewing
angle while mounted on the blade, hold the panel with one hand and
adjust the angle with the other.
