Xiaomi’s rumored “Pocket Guitar” accessory may turn the phone’s rear screen into a music controller

Xiaomi may be developing a small flip-style accessory designed to work with the rear screen on its upcoming flagship phones. Developer Kacper Skrzypek found related code and renders suggesting a controller with buttons and touch-sensitive grooves that could simulate guitar chords and strumming. The accessory appears to depend on China-focused karaoke app Changba and may be designed specifically for Xiaomi phones with rear displays.
