Just Two Days After Release, iPhone 18 Pro Users Worldwide Report Sudden Reboots and "Panic Full" Issues

Shuts Down and Reboots During Face ID and Apple Wallet Use

"Four Times in a Day" Similar Cases Reported Overseas

Recently, users in South Korea and abroad have reported that some units of Apple’s newly released iPhone 18 Pro and iPhone 18 Pro Max are experiencing the so-called "Panic Full" phenomenon, in which the device suddenly shuts down and then restarts. In particular, cases have emerged of repeated issues during Face ID authentication, drawing attention to the possibility of an initial software error.

On September 20, numerous reports were shared on domestic iPhone user communities and overseas online forums from iPhone 18 Pro and Pro Max owners who experienced unexpected reboots.

The term "Panic Full" refers to a situation in which the iPhone, while functioning normally, suddenly halts or powers off due to a system error, then automatically restarts. When the issue occurs, users can sometimes find analysis logs starting with "panic-full" in their iPhone by navigating to Settings → Privacy & Security → Analytics & Improvements → Analytics Data.

In South Korea, some iPhone 18 Pro users claimed the issue occurred while using features that require Face ID authentication, such as financial apps or photo apps. They reported that repeatedly attempting authentication with the Face ID sensor covered would cause the device to shut down and restart. Multiple users testified that the issue could be reproduced by repeating the same steps several times.

Other users asserted that Panic Full also occurred during the initial setup process or while using ordinary apps. IT YouTuber "Jooyeon ZUYONI" announced that she confirmed the same symptoms on her own iPhone 18 Pro while verifying user reports.

Similar cases were also reported overseas. In a dedicated iPhone 18 Pro community on Reddit in the United States, one user posted that they experienced four forced reboots within less than 24 hours of purchasing the iPhone 18 Pro Max.

This user claimed that three of the reboots happened during Face ID use, and one occurred while launching Apple Wallet. The user explained that the problem temporarily disappeared after resetting Face ID, but recurred the following day while running Apple Wallet. In the comments, other iPhone 18 Pro and Pro Max owners reported experiencing similar symptoms.

This is not the first time that controversy over the Panic Full issue has arisen right after the launch of Apple’s new iPhones. Similar complaints were reported by some users of the iPhone 16 series, released in 2024, who experienced devices shutting off and restarting unexpectedly. At that time, reports largely centered on the iPhone 16 Pro and Pro Max, and Apple subsequently addressed the unexpected reboot issue for some models through the iOS 18.1 update.

Meanwhile, Apple has yet to release an official statement regarding the alleged problem with the iPhone 18 Pro that users are reporting.
