Quick Tip for iPhone Users
If your video freezes, becomes half-screen, or behaves strangely when switching to landscape/fullscreen mode, one possible reason may be your iPhone’s display scaling settings.
On some iPhone models, using larger display zoom or text size settings may affect fullscreen compatibility in certain apps.
You can try the following:
Go to:
Settings → Display & Brightness → Display Zoom
Change it to:
Default
Completely close and reopen the aosu app
If you still experience the issue afterward, checking your Text Size settings may also help:
Settings → Display & Brightness → Text Size
Our team is continuing to improve compatibility for different iPhone display settings in future updates.
