I'm using the iOS 18+ RecognizedTextRequest, and with no change of code, iOS 27 gives poorer results:

lines are dropped, all the text is not recognized
it's not my code, because Live Text has the same issue
and of course, back to 26 or 18 solves the issue

What changed?

Only interesting infos I could isolate:

The simulator has not the issue
Squashing the image horizontally (80% of its width for example) makes the detection significantly better

I and thousands of users of my app Highlighted are seeing the exact same issue. Can we please get an update from Apple on this critical issue?

I have the same problem in my OCR test suite. It's a shame that the new iPhone 18 Pro with iOS 27 is getting worse recognition results than iPhone 14 with iOS 26 & have to do the width sampling & merge to get to smth close iOS 26 produced.

Just run into the similar issue... We use Apple Vision OCR on ReplayKit frames: VNRecognizeTextRequest with .accurate recognition. Simulator on iOS 26 is fine but not iOS 27 on my development iPad, which I can't downgrade... I feel lucky I caught this issue before it causes problems for our clients.
