The iPhone 18 Pro and iPhone 18 Pro Max went on sale on September 18, 2026. Within about a day, owners started posting the same symptom on Apple's Support Community and on social media: the screen goes black, the Apple logo appears, and the phone reboots on its own. By September 20, one thread on Apple's forums had picked up almost twenty "Me too" votes.
If you bought one of these phones and it has done this to you, the short version is: it is a known software bug, not a broken unit, and Apple has already said a fix is coming.
What actually triggers it
The pattern that keeps showing up in reports is a failed Face ID attempt inside an app rather than on the lock screen — trying to unlock the Passwords app and having Face ID not recognize your face, for instance. When that happens, the phone can stop responding to touch and then hard-reboot a few seconds later. Macworld reproduced the freeze by covering part of its face during a Face ID check, and found a "panic-full" entry logged in the phone's analytics afterward, the marker iOS leaves when a serious crash forces a restart.
It does not happen to every 18 Pro, and nobody outside Apple has said what share of units are affected. What the reports agree on is the trigger: a failed Face ID scan, not general use. Reports so far are specific to the Pro and Pro Max, not the base iPhone 18, and Macworld's writeup floated a possible reason: the 18 Pro line carries a redesigned, smaller Face ID sensor array, which the base model does not. That is a plausible link between hardware change and software bug, not a confirmed cause — Apple has not said what in the code is actually failing.
Apple confirmed a fix, and gave a rough date
Apple told 9to5Mac on September 23 that a software update addressing the problem is in development and should be available early the following week — the week of September 28. Apple has not confirmed a version number; press coverage is guessing iOS 27.0.1, but that is a guess, not something Apple has said. Treat the date the same way: it is Apple's own estimate, not a shipped update, and estimates for software updates move.
What to do before it arrives
Until the update lands, the practical move is to avoid repeated Face ID retries — if a scan fails, use your passcode instead of tapping to try again. If the phone does freeze, a force restart clears it: press and quickly release volume up, then volume down, then hold the side button until the Apple logo shows. Some owners reported Apple Support running diagnostics and offering a replacement unit before the fix was confirmed; if you already went that route, a replacement should behave the same as your original phone until the update ships, since the cause is software, not a specific bad batch of hardware.
Does this change whether the phone is worth having
No, and that is worth saying plainly. A launch-week bug tied to a specific sensor interaction, with a fix already scheduled, is a different situation from a hardware flaw with no fix in sight. If you already own the 18 Pro or Pro Max and it has not shown the symptom, there is nothing to do but install the update when it arrives, the way you would any other patch. If you were weighing whether the sensor redesign on this generation changes anything else about how the phone works day to day, what actually changed on the iPhone 18 Pro covers that separately from this bug.
Watch two things rather than assume them: whether the update actually ships in the window Apple gave, and whether it is a clean fix or needs a follow-up patch, which happens often enough with launch-week bugs that it is worth checking your software version again a week after installing it. For a longer look at what reviewers found once they had the phone in hand past the Face ID story, MKBHD's review focused on the chip is the one to read next.
