My mobile LR's subject detection fails to work since few days ago, probably starting from last update. It does not even work on simple portraits (see attached, emoji and rectangle drawn on screenshot only).

Desde que lo he actualizado la IA no encuentra SUJETO cuando es fácilmente identificable e interpreta que el fondo es TODA LA IMAGEN (SUJETO Y FONDO)

HI @Vero, thanks for reaching out! Could you share a screenshot or a short screen recording demonstrating the issue? Along with example pictures? Also, can you send your system info? You can find your system info by going to Help > System Info, copying and pasting it into a text file, and attaching it here. Thanks! ^CH

I have attached three photos here: my Lightroom version, my phone's OS details, and a sample of the subject detection error. As you can see, it completely missed the subject (the cat) and instead randomly selected something in the upper left-hand corner of the photo.

Regarding my phone's OS: I actually started experiencing this subject detection issue about two weeks before I even updated the operating system. I have also tried running the subject detection in Airplane Mode as well as over Cellular Data, but it still fails to detect the subject..

Hi @leo31882846ifrr

Thanks for reaching out. Could you please share a few more details so we can better understand the issue?

Which version of Lightroom are you using?
Could you share a screenshot or a short screen recording demonstrating the issue?
Does this happen with all images, or is it specific to certain photos?

Looking forward to your response.

Thanks, Srishti Bali | Community & Engagement Strategist, Digital Imaging | Adobe

@Sameer K Attached a recording. The subject detection is ... not working at all. I've tried both raw (CR3) photos and JPEG photos, and the results are the same (i.e. not working).

Lightroom mobile version: 11.4.3

Android 16, One UI 8.0
