The Galaxy Z Flip 8 no longer needs Good Lock for this cover screen feature

TL;DR The Samsung Galaxy Z Flip 8 now offers a button to change the aspect ratio of apps running on the cover screen. This feature previously required the MultiStar app, but it’s now built into One UI 9 on the new Flip phone. The button also supports Labs apps this time, allowing you to adjust the aspect ratio of Google Maps, YouTube, and more.
