Abstract: A stability structure for a mobile electronic device is provided. The stability structure includes a plurality of aglets. An elastic member is connected to and extends between the aglets. The elastic member is placed against a back surface of a mobile electronic device or a back surface of its protective case. Adhesive members attach the aglets to the back surface of the mobile electronic device or the back surface of its protective case. In an installed position, the elastic member and the back surface of the mobile electronic device or the back surface of its protective case form a gap to receive a user's fingers. The elastic member urges the inserted fingers against the back surface of the mobile electronic device or the back surface of its protective case thereby allowing the user to securely hold the mobile electronic device with one hand.
