Frozen screen bug
Alleged bug number one: in some cases and at some times, the iPhone 18 Pro’s screen is believed to stop responding to touch. One owner posted a video of this behavior to Twitter/X; their thumb appears to swipe up and down on the display (while using a social media app, possibly Twitter), yet nothing happens in response.
When a commenter on the post claimed that this is a bug in iOS 27 rather than the iPhone 18 Pro, and that the poster “swiped down both Notification Center and Control Center at the same time which causes the phone to freeze,” the poster responded that they didn’t “exploit any bug” and that the problem has happened twice already. Then they link to a second user reporting the same issue.
We’ve also seen a similar complaint about touch sensitivity on Reddit, although this might have a different cause; the owner mentions use of a screen protector.
Face ID bug
Alleged bug number two: a Face ID bug has caused some iPhone 18 Pro handsets to freeze and then reboot. What appears to happen is that when a Face ID verification fails, the behavior triggers.
A thread on Reddit contains the following complaint: “Not even 24 hours and I have my 18 Pro Max panic restarting. Three times due to Face ID and one by some timeout (whilst loading Apple Wallet). Called Apple support, done a Face ID reset after three restarts.”
Of the 24 direct responses from other users, 22 confirm that they’ve experienced the same or a similar issue. Some speculate (as we saw with the touch sensitivity bug) that it could be an issue with iOS 27 or other software rather than the new hardware. As evidenced by the testimony of one commenter and the original poster, the bug affects the 18 Pro Max as well as the 18 Pro.
