The LG Wing Developer’s Guide shows how to use the second screen

In about 12 hours, LG will be unveiling one of its craziest smartphones to date. After trying the dual-screen idea and not really interested in an expensive foldable phone, they’ll put a smaller second screen under the main screen instead. The LG Wing’s swivel system is sure to raise a few eyebrows for both users and developers. So it has prepared its new mobile developer portal to explain why app makers want to take advantage of the unconventional additional real estate.

The primary use case for such a second screen is of course multitasking with two apps running at the same time. While Android already supports split-screen apps, the LG Wing can run at least one of the apps completely. This is ideal for playing videos while chatting or navigating while listening to music.

However, the LG developer documentation discovered by NextPit is trying to sell the idea of ​​an “app extension”

; that allows a single app to use both screens for different but related purposes. For example, a video editor might display the main playback screen at the top and the controls at the bottom. Even a simple video player can benefit from this expansion mode by moving playback controls and other user interface elements to the smaller second screen, leaving the video screen clean and free.

Of course, this latter app expansion mode requires app developers to put in more work than they normally would to support such a rare phone. However, one particular use case could prove interesting for developers as it allows advertisements to be displayed prominently on the second screen. This would mean that users would not be interrupted while watching a video, but would still see ads in full when the second screen was not shown.

The LG Wing is definitely turning out to be a curious phone, but unfortunately, LG takes more than just curiosity to bring this novel phone up for sale. There is still some uncertainty about the specs and pricing of this phone, and given the time, uncertainty is something that consumers don’t need right now.
