Since the release of the iPhone 18 Pro series on September 18, 2026, a significant number of user feedback reports have emerged across various user communities, highlighting issues such as system crashes and automatic shutdowns and restarts, known as the 'Panic Full' phenomenon. These issues occur in diverse scenarios, with some related to Face ID usage, such as device crashes and restarts after facial recognition failures, and others unrelated to Face ID, like sudden device freezes and restarts while watching videos, listening to music, or turning on the flashlight. Similar problems have also been reported in the U.S. market. Additionally, some users have complained about paint peeling and deformation issues with the aluminum alloy casing of the series. A digital market operator in Hangzhou mentioned that such problems occur at a relatively low frequency, and devices purchased through official channels can be exchanged, while those activated in digital markets or authorized stores are not eligible for exchange. Consumers are reminded to carefully inspect their devices before activation.
