Vertical Lines on my iPhone 16 Pro Max display

I have this too. It happens multiple times a day and I'm running 18.2.1. It usually happens when I tap the always on display to unlock it. I think I read somewhere that turning off the always on display stops it, but that's one of the features that prompted me to upgrade. It's getting really annoying now.

Is anyone still experiencing the issue (split second vertical lines)? Apple replaced my phone 10 days ago and I haven’t seen the issue since. So I am inclined to think it was a hardware issue, unless the iOS 18.2.1 update fixed it?

I do still have the vertical lines issue even after all these iOS updates including this most recent one. I intend on going to the Apple Store and swapping it out as soon as I return from my vacations this season. By then they should more than have enough new batches by then that aren’t from the same original one that generated this issue. I will be keeping my eyes and ears open to these discussions as we are still hearing about people having this issue on new phones. Mine continues on occasion when I activate Siri using the side button, and on occasion when I get a notification. I have had a few games crash on me as well, and they are in Apple Arcade. That’s concerning.

Yes. I set up a shortcut on the 21st to log it every time I saw it. They're in UK time zone:

Hi everyone. Since 18.3, I haven’t experienced the vertical stripes even once!!!! Unbelievable that others are still having this issue. In 18.3 RC, I still had the problem. Before that, I experienced it multiple times a day. Since 18.3, everything has been fine—I hope it stays that way. 😌

I still experienced them in 18.3. Go a few days without restarting your phone and you'll see them. I'm pretty sure it's a software issue where there is some graphical degradation over time the longer the phone is up without a reboot. There have been several graphical issues like this with animations in the past. I've been on 18.3.1 since yesterday. No issues yet but I usually start seeing it after about 2 days of uptime.

Hello, I have been experiencing the same issue since I bought my iPhone 16 Pro Max in January 2025, so it seems that no updates have fixed it until now. I have been considering sending the phone for repair to Apple service, but I see that it does not guarantee a solution to my problem. Is this something that will be fixed with an update, or is it a hardware issue? Has anyone received a direct response from Apple or knows how this issue is usually resolved with these models?

That's the point. This is a user to user only forum. Apple doesn't participate here, so if you want to hear from anyone at Apple it will NEVER happen from posting here. You can consider my comment useless, but since you clearly don't know you are only addressing other users, none of whom work for Apple, maybe what I posted isn't useless after all? Schedule an appointment at your Apple Store Genius Bar if you want help from Apple. You won't get it here.

Are you still facing this problem?

This my message that I wrote in another post of someone also having this very same issue

Same to me 1-2 times a day with barcode vertical line

I have the same problem also with vertical lines appearing randomly for a fraction of a sec more often now. Any news from Apple on this issue?

Hi all!“I have the same issue with the 16 Pro Max! According to Apple, it’s a software problem and they are working on a fix.”

Same here. Very disturbing. I don’t want to exchange it until they recall it or something.

oh yeah? Where did you get this info that they are working on that specific issue?
