P: Subject detection not working on Android LrM v11.4.4

Participating Frequently

I updated the app today, v11.4.5 and tried using the subject detection feature, but it still failed to detect the subject. Please see the attached screenshots.

@Jysn_Tndn, thank you so much for sharing your information! Would you mind sharing your OS information and a sample media file that isn't working for you? Are all images or just particular images? This will really help us try to recreate this issue and fix it. Thanks! ^CH

I didn't mean to finish the report, just pressed the wrong button resulting "correct answer" and there seems no way backward. The issue still persists.

@aaron.hkg, Not a problem! The Correct Answer has been removed. Would you be able to send sample media as well as images that are not working for you? ^CH

My phone is a Samsung A55. Everything was fine until recently; now, when I edit a photo and use the subject detection feature, Adobe Lightroom Mobile detects everything but the subject. I've already cleared the app's cache and updated it, but that didn't work. I even uninstalled and reinstalled the app, and it still didn't fix the issue. It's really frustrating.

HI @Jysn_Tndn, thanks for sharing all the steps you’ve taken to try to fix this issue. Would you be able to send which version of Lr you are using on your phone, OS version, and a screen recording of what you’re seeing? That would be very helpful in replicating and fixing the issue. Thanks for your patience! ^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.

I can't upload a video directly here, so I have uploaded a screen recording to Google Drive. You can access it via the link below:

You need to give more information about your system. Go to Help - System Info in Lightroom and post that here. The most common cause of problems like this are (on Windows computers) outdated GPU drivers.

I put a picture with an obvious subject, a person. And light doesnt detect it.

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
