How to Fix Dynamic Island Rendering Glitches on iPhone 18

When an app draws content behind the Dynamic Island, first identify whether the issue appears in one app or throughout iOS. A user report of a rendering problem does not confirm an iPhone 18 system-wide bug.

Test the app-side branch

Close and reopen the affected app, then update it from the App Store.
Restart the iPhone and install an available iOS update in Settings > General > Software Update.
Compare the same view in another app. If only one app has the overlap, send the developer a screenshot, app version, and steps that reproduce it.
Wait for an app or system update rather than repeatedly changing unrelated display settings.

When it may be broader

If the problem persists across Apple and third-party apps after updating and restarting, capture screenshots and contact Apple Support. Avoid presenting a workaround as a confirmed repair until the affected app or Apple identifies the cause.

If Apple's built-in steps do not resolve a broader software problem, Dr.Fone - System Repair provides a guided desktop workflow for iOS system issues before you consider a full erase.
