Why is half of my iPhone screen blank?

Ok so my issue resolved. I had to turn off “reduce transparency” under the accessibility settings.

Accessibility->display & text size-> toggle “reduce transparency” off.

Hasn’t happened again.

Unfortunately, this fixed my issue. I had the reduce transparency enabled as the transparency appeared to slow my phone down. After disabling it, I have not seen the half screen issue any more. Seems like Apple offers a feature to improve the phone speed at the cost of functionality. Hopefully it will be fixed in 26.2.

Not sure if it would help but you said you are on iOS 26.0.1. There is a newer version that just came out, 26.1. Try updating to that version.

Did you restart your phone?

Press and release volume up then volume down, then press and hold the side button until you see the Apple logo.

I regularly experience the same 1/2 blank screen but ONLY for Messages.

1) I have restarted my phone.

2) I am running 26.1

The glitch occurs inconsistently. Sometimes at iPhone startup. Sometimes after lack of Messages app use for short or long periods.

It occurs regardless of having an unread message or no unread messages.

It resolves itself if I touch the Search field at the bottom or if I touch a pinned contact at the top.

Super irritating. Also super irritating is that one person’s response that the OP didn’t include any “really” helpful info.

That response wasn’t really helpful. Do better.

"Why is half of my iPhone screen blank?: Why is half of my iPhone screen blank?: For several non-native apps, the lower half of the screen is blank. I believe this began happening when I upgraded to iOS26 a few weeks ago."

All the more reason to always install the latest update.

This started when I updated to 26.1, so it’s not fixed. As mentioned previously, the app content scrolls behind the blank lower part of the screen.

It happens when I switch from one app to another, then back to the first. In Notes, if I press the back arrow and reopen the note, it’s gone.

Does not seem to be app-specific, but from the size and position it seems like it might be tied to the onscreen keyboard.

So I toggled on reduce transparency because the new update to Liquid Glass really hurt my eyes and gave me headaches. So I have this same problem with my screens being half blank, but this wouldn’t be the solution for me. Any other thoughts? Attached is an example of it

Super annoying!!! 3/4 of my screen is blank but can school at the very top to see there are messages or emails. Sometimes I can tap on the top email or text but then I have to get out of it to view what I wanted to view. 

either don’t buy the 17 pro or the iOS needs attention. Never had this problem until I got the 17 pro recently from a 15 pro. 

also, the 17 pro doesn’t come up as a 17 pro it registers as a 15 pro and glitches and shuts off when apple play is on. WTH apple?
