Seems perfectly fluid to me. See screen recording I just made below (I used a different PDF file that had more pages to serve as a better example):


I'm using an iPhone 13 Pro Max on iOS 15.0.1

Oops. Yes I did, I also meant to add it’s on my 13 Pro
Can you tell me if the 15.1 betas you are testing has a fix in it for the touch screen response, where you touch the screen that the touch is not registered? There also seems to be bug in the battery usage algorithm in iOS 15, do you know if that has been fixed in the 15.1 betas? And your battery life using 15.1 betas?

Yes I have this issue as well. However when I activate screen recording it goes back up to 120hz. I’m on 15.1 beta 3

Ah, didn't notice this before, but you're right that for some reason the screen recording makes a difference (odd, because you'd think that screen recording would slow things down, not speed things up). However I don't think it's actually the screen refresh rate that's the issue. In the PDF file I was demonstrating with, it seems like the scrolling is "arrested" consistently at each page break. If I zoom in on a single page and move it all around, it's definitely 120Hz smoothness.

I haven't experienced any of these bugs. Granted, I have had 15.1 beta 3 on my iPhone 13 Pro since I first got it.

iPhone 13 PM on iOS 15.1 beta 3 and I’m experiencing it. Coincidentally, I noticed this earlier today and stumbled upon this post by chance now. I’m also still experiencing touch not registering sometimes.

Still noticing this on the RC. Very frustrating. Can we all report it via the feedback app? I've sent 2 in so far (beta 4 and RC).

Edit: applefeedback:// for those of you not on the beta!
