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).

I've been going through the same problem on mobile, latest version of both Lightroom and my OS, on a Samsung Galaxy A55.

I have reported the same issue around 1 month ago. Issue has NOT been fixed and I haven't received updates from the supports for more than a week already.

PS. It seems to be a compatibility issue with certain Android devices (myself using Samsung A55).

That seems very strange. I took the liberty of screengrabbing your grabs and taking them into my Lightroom Mobile.

I am using an iPhone 16Pro on the latest OS. Both Select Subject as expected.

How did the photos get into Lightroom Mobile?

Imported, taken with the device camera or synced from Lightroom Classic?

Checking the app and OS are up to date is a start. Also have you tried reinstalling the app (making sure any syncing to the cloud has completed first)?

Maybe a member of the team or another Android user will comment if they experiencing the same issue.

I transfer the photos via an adapter that plugs into my charging port.I import them to a sd card and from there I do my culling and import them to LR mobile,and everything is up to date only thing I haven't tried is uninstalling and re installing

I've been using Lr mobile for about 5 years now,and just recently the auto select on masks has been buggy,it'll select random spots of the photo or just say no subject found(some examples below) Im on a Samsung A55 with 8gb ram

I have the same issue and it has started after the latest update. I am unable to fix this by clearing the cache or completely clearing the storage either.

I've already cleared the cache and cookies, reinstalled the app, and updated to the latest version (v11.4.5). I also uninstalled Snapseed and tried running the subject detection in airplane mode, on mobile data, and over Wi-Fi. Still, it isn't detecting the subject.

Yeah. I went through all that as well and nothing changed. Can't detect subject.

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:
