A mini OS for your Flip's cover screen!
CoverScreen OS turns your flippable phone's cover screen into a full secondary OS.
Run apps, widgets, notifications, media controls, quick toggles, caller ID, keyboards and clock faces directly on the outer display. It is designed to go beyond the stock cover screen experience on supported flippables, including Samsung Galaxy Z Flip 3/4/5/6/7/7 FE, Motorola RAZR 40 Ultra/Plus, RAZR 50 Standard/Ultra/Plus, RAZR 60 Standard/Ultra/Plus, RAZR 70 Series, OPPO Find N2/N3 Flip and Vivo X Flip.
Features vary by device model, software version, region and OEM limitations. If you have any issue with a purchase, need help setting up, or want to request a feature, contact dev+csos@ijp.app.
CSOS also works alongside the phone's stock cover screen features. Use the in-app tutorial to learn the navigation system and switch between CoverScreen OS and the OEM cover screen experience.
