iPhone captioning for calls doesn’t work after latest update

Hi Prhenley

welcome to the Apple (user-to-user) Community.

Re: "Since the latest update, iPhone captioning for calls doesn’t work.

Occasionally, a few words will show but then captions stop. "

Am no expert in this area, yet your post to the community deserves some response.

Wondering if Apple Support's online article fior iOS 18 may help:

Get live captions of spoken audio on iPhone - Apple Support

Eg: says:

"Set up and customize Live Captions

1. Go to Settings > Accessibility > Live Captions, then turn on Live Captions.
2. Tap Appearance to customize the text, size, and color of the captions.
3. By default, Live Captions are shown across all apps. To get live captions only for certain apps such as FaceTime or RTT, turn them on below In-App Live Captions.

There may or may not be other useful / applicable tips in the above linked article.

Else: For support or help with accessibility features:
