Galaxy Z Flip3: Bring added versatility to Samsung's clamshell foldable with CoverScreen OS
The Galaxy Z Flip3 has a much larger secondary display than its predecessors, albeit not as large as the one that Motorola included in the Razr 5G. Also, Samsung restricts the secondary display's functionality to a few features, such as displaying incoming notifications. By contrast, Motorola allows people to treat the Razr 5G's equivalent display more like an actual smartphone, should you wish to use it like that.
With that in mind, a developer with the XDA Developers Forum username Jagan2 has brought added versatility to the Galaxy Z Flip3's front display with CoverScreen OS. In short, CoverScreenOS is an app that allows you to use the 1.9-inch display to view your home screen, launch apps and control music playback. Hence, CoverScreen OS allows Galaxy Z Flip3 owners to launch Google Maps without opening their devices.
The video embedded below shows how CoverScreen OS works and the gestures that it supports. Jagan2 states that CoverScreen OS is at an experimental stage, currently. Still, he considers that the app is 'mostly usable' on his test device and has published the CoverScreen OS app on the Google Play Store. Newer builds will arrive first on the XDA Developers Forum post, though.
