Abstract: A mobile phone case includes a cradle for receiving the smartphone in a friction fit configuration, an upper frame portion coupled to an upper section of the cradle and a lower frame portion coupled to a lower section of the cradle via upper and lower rail assemblies, respectively. The upper and lower frame portions are slidably movable between a closed configuration covering the upper and lower microphones and the front and rear cameras of the smartphone, respectively, and an open configuration not covering them. The upper and lower frame portions include dampening members configured to block audio and visual signals when closed. The mobile phone case includes a spring-biased selector assembly coupled to the cradle portion and operatively coupled to the upper and lower frame portions for simultaneously urging the upper and lower frame portions toward the open configuration when actuated.
