Problems started fast for iPhone 18 Pro and Pro Max owners after the iOS 27 update. Many users now face phones that freeze or restart out of nowhere. The trouble often begins when Face ID fails to unlock apps like Passwords.

It is not just one glitch. Some people say their screens lock up if they open Notification Center and Control Center at the same time. Others report a full reboot after Face ID fails. The new Face ID system seems to be the main cause. Phones freeze. Sometimes they restart without warning.

The Face ID-related bug is not affecting all iPhones running iOS 27, but is limited to the iPhone 18 Pro and iPhone 18 Pro Max models, according to independent reporting.

ET Now News

Apple has admitted there is a problem. The company says a software update is on the way. While Apple has not named the version, iOS 27.0.1 has already shown up in analytics. Most expect this update to fix the freezing and reboot issues. 9to5Mac reports the patch should arrive early next week. It will target the main bugs directly.

Face ID is not the only thing broken. The large Calendar widget has its own bug. Romanian tech reviewer Marian Cruțu (@MegaMarian12350 on X) showed how a certain tap and swipe pattern makes the widget flicker or show "No Events" even when there are events. This adds to the list of complaints since iOS 27 launched on September 14.

Apple's advice for now is simple. Force restart your phone: press volume up, then volume down, then hold the side button until it reboots. When the fix is released, update right away in Settings > General > Software Update. That should bring back stability.

Apple is preparing iOS 27.0.1 as an emergency patch to address freezing and unexpected restarts on iPhone 18 Pro and Pro Max, with a release targeted for the week beginning September 28, 2026.

Apple is moving fast to fix these high-profile bugs. Even top-tier phones and major updates can have serious problems. Apple's public response matters, but this episode shows the risk of updating early. Quality control is key for both hardware and software. For iPhone 18 Pro users, the next update cannot come soon enough.

ET Now News reporting confirms iOS 27 came out on September 14, 2026. Complaints about freezing started soon after. The fix is expected within one to two weeks of launch.
According to a MacRumors update, the main issue is a software bug in Face ID, not a hardware fault. Apple urges users to install the update as soon as it is available.
