Notification center not working while in landscape mode

iOS15 is a while ago, not sure anyone will remember if it was a feature . It is a feature on home button phones with iOS26.

Try force restarting the phone Force restart iPhone - Apple Support

"Press and hold both the Sleep/Wake button and the Home button at the same time. When the Apple logo appears, release both buttons."

Whenever I’m in landscape mode and try to click on a notification in the notification center, or try to clear all of my notifications, it doesn’t work. Does anyone know how to fix that? I already restarted my phone

I just tested this on my iPhone 17 Pro, iOS 26.2. It worked fine for me.

Is it in all apps in landscape mode? Or just some? Or one?

In addition to LD150's suggestion to force restart, I'd also suggest updating to iOS 26.2.

I already force restarted. And I don’t know why apple marked this post as with my iphone 6. I clicked my iphone 16. To clarify, this post is about my iphone 16 ios 26.1. Sorry for the confusion!

No problem, so we established that it should work,

Next step would probably be a backup and restore if you think it is worth the effort.
