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.

There is a somewhat similar issue https://github.com/immich-app/immich/issues/18577, so I'd like to check your case
i don't have that exact image from the screenshots anymore, but here's another that's having the same issue

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 have the same issue
@Francisco could you describe steps to reproduce the issue from your side?
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?
Mobile app only



Thanks!
I experimented with the image from the zip archive shared earlier.
Extracted that internal small thumbnail (just 7 KB).
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
[Issue] Sideways/upside down live photo previews on web timeline for photos taken with front camera on iPhone (immich-app/immich#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
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)
makes sense to me
