Backwards selfie thumbnails

Thumbnails of photos taken with the selfie camera on my Pixel 10 Pro are flipped on the timeline. Below is the original photo and the way it appears on the timeline.

Hey @근영 could you share the photo as (zip) archive here? There is a somewhat similar issue https://github.com/immich-app/immich/issues/18577, so I'd like to check your case

Seems I cannot reproduce. The image looks the same in timeline (thumbnail) and in photo view (preview) and when downloaded (original). I used web UI only though. Is your issue specific to the mobile app? Or it happens in web UI too?

I'm unable to reproduce the error with new selfies, but let me record a video to show it

1. Does it occur in web UI? 2. Does it occure in mobile app?

I experimented with the image from the zip archive shared earlier.
exiftool -G1 PXL_20250909_135542370.MP.jpg
[IFD1] Thumbnail Image : (Binary data 6709 bytes, use -b option to extract)
exiftool -G1 PXL_20250909_135542370.MP.jpg
[IFD1] Thumbnail Image : (Binary data 6709 bytes, use -b option to extract)
Extracted that internal small thumbnail (just 7 KB).
exiftool -b -W %d%f_%t%-c.%s -ThumbnailImage -MotionPhotoVideo PXL_20250909_135542370.MP.jpg
exiftool -b -W %d%f_%t%-c.%s -ThumbnailImage -MotionPhotoVideo PXL_20250909_135542370.MP.jpg
And that embedded thumbnail does appear mirrored/flipped (in any image viewer).

weird. i have selfies set to not flip, which i believe is not the default setting on the phone perhaps google just forgot to have the setting update thumbnails as well i opened an issue for a similar problem with my iphone too #20712

perhaps immich could account for this and flip thumbnails accordingly? only in the mobile app

It's strange as it mirrors only on the general timeline and not in the recently created album
Sergey Katsubo
Summary/hypothesis (?) - For the main Timeline mobile app uses low-res thumbnail (embedded in the photo). - Photos taken with Pixel front camera may have that embedded thumbnail flipped / mirrored (compared to the main jpg). - Therefore in Timeline these low-res thumbnails appear flipped/mirrored. - In all other places, except for Timeline, the app uses generated thumbnails/previews which are based on the main jpg, therefore they are oriented correctly. (I'm not a mobile dev, so take it with a grain of salt, it's just hypothetical explanation)
