A mobile device holder includes an attachment assembly and a support assembly. The attachment assembly includes a magnet enclosed in a shell. When brought into proximity to a magnetic part of a mobile device, the magnet causes the mobile device holder to be attached to the mobile device by magnetic attraction. The magnet has a ring shape. Toward the center of the ring-shaped magnet, the attachment assembly has an accommodating recess. The support assembly includes a handle that is movable on a hinge in and out of the accommodating recess. The joint permits the handle to rotate about a first axis and a second axis not parallel to the first axis.
