Systems and methods for protecting a mobile device screen utilize a screen protector overlying the display screen lens, wherein the screen protector includes a conductive region. The device face includes a plurality of conductors underlying the screen protector at the conductive region. The conductors are capacitively coupled in the presence of the screen protector, and are capacitively decoupled when the screen protector is removed. This allows the device to detect removal of the screen protector and to perform a responsive action such as alerting a device user that the screen protector is not installed, instructing the user to install a screen protector, storing an indication that the screen protector is not installed and transmitting an indication that the screen protector is not installed.

Capacitive detection of screen protector removal in mobile communication device

An electronic device includes a housing and an electrical connector disposed along the housing. The electrical connector includes one or a plurality of electrical contacts having at least a portion thereof exposed to an exterior of the housing. An interface circuit is operable with the electrical connector and coupled to one or more electrical contacts of the electrical connector to interact with a complementary connector when connected to the electrical connector. A moisture detection circuit is to detect moisture contacting the electrical connector.
