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. Xiaomi has not officially confirmed the product or its launch plans. [IT Home, in Chinese]
