Issues with the magnifier on the iPhone 15 Pro

Hello everyone,

My name is Kevin and I’m from Germany. I’m new here in this forum and would like to introduce myself briefly:
I have been blind since birth and I use an iPhone 13 and an iPhone 15 Pro.
Like probably all of you, I have grown to love the new features with artificial intelligence and image descriptions. I even take a lot of photos myself, ever since this feature became available.
I am a big fan of the football club Borussia Dortmund and I am often at the stadium. With these new great features, I can finally experience the stadium. If you like, follow me on Twitter.

Now to my problem.
At Apple, there is the app magnifier.

The app works perfectly. Text recognition works wonderfully. Door recognition as well. What doesn’t work at all for me is the image description function.
My girlfriend received her new iPhone 15 Pro today, which is exactly the same iPhone as mine, and the image description works perfectly for her. We went through all the settings together, and we have all the same settings. The image description works for my girlfriend. Not for me. The voice output doesn’t say anything at all.
The voice output is turned on everywhere, but there is no description at all. As I said, the rest, the text recognition, and all other functions work perfectly.
Do you maybe have a solution for me?
Of course, I’ve already looked on Google but didn’t get any results at all. Maybe you have a solution for me.
Best regards and maybe we’ll see each other often on Twitter.
Kevin
