If you’re observing old or previously uninstalled apps inexplicably showing up on your iPhone following the update to iOS 18.4, you’re not alone in facing this peculiar issue.

Numerous users have taken to Reddit and Apple’s official Community forums to indicate that apps—some of which they had deleted a long time ago—are unexpectedly reinstalling themselves after the iOS 18.4 update. In certain instances, users report that unfamiliar apps they don’t recognize are also surfacing on their devices.

One Reddit user recounted their experience, stating, “After successfully updating to iOS 18.4, I visited the App Store to refresh some apps. To my astonishment, this Chinese game installed itself automatically. How is that even possible?”

Another user mirrored this bewilderment, commenting, “I didn’t recognize the game. It’s possible I downloaded it once to give it a try, but that would have been a long time back. Very unusual.”

The reports seem to cover a range of iPhone models, including the iPhone 15 and iPhone 15 Pro Max. However, not all users are experiencing this issue. Some individuals, including the writer of the initial article, noted that after updating their iPhone 16e to iOS 18.4, they did not encounter any unexpected installations. Other Reddit contributors have also indicated a lack of issues.

At this juncture, the advisable step appears to be to manually remove any unwanted or unexpected apps that might have re-emerged on your device. There’s been no official statement from Apple as of yet, so we’ll need to await further insights or a possible resolution.

iOS 18.4 started rolling out earlier this week, bringing Apple Intelligence to additional regions, alongside updates to Apple News, improvements to CarPlay, and a new selection of emojis.
