On one thread on Reddit, dozens of ‌iPhone 14‌ Pro users are reporting that one or more green and yellow lines may flash across the screen before disappearing a few seconds later when the device is being turned on. According to those same users, Apple Support has informed them the issue is not a result of a hardware defect but is a bug in iOS 16.

According to users on Reddit, the Apple Support forums (1,2,3), and the MacRumors forum, the issue seems to have started following the iOS 16.2 update, although some users report the problem even occurring on older versions of iOS 16. One user on Reddit claims an Apple engineer informed them over the phone that Apple is working on a software patch for the issue, but the exact details are unknown.

Apple is currently testing iOS 16.3 with developers and public beta testers, but the update isn't expected to launch until early next year. The latest version of iOS 16 is iOS 16.2, which included several new features, including Apple Music Sing, Apple's new Freeform app, and more.

Not sure what's the problem in the second picture but the guy on the left is probably The One.

Complaining about flashing green lines on boot up? These people clearly never grew up with old green monochrome CRTs. If it didn't flash green lines on boot you'd think something was broken. ?

Does “turning on” mean booting up? I reboot maybe once or twice a year — how is this even an issue?

Seems a bit unfair, that only some people are getting a new boot animation!

Honestly, if it wasn’t there before, is cosmetic, only happens during startup, has no detrimental effect on using iPhone…

Then it’s really not a big deal, is likely software-related, and will probably be fixed in the next point release.

Go and enjoy Christmas / the festive season!
