I just purchased the 3a and I took photos using the primary and selfie cameras with the default settings with the default firmware (with the December 2024 patch). I then updated to the latest firmware (with the February 2025 patch) and took the photos again to compare.
I found that selfies taken before and after the update were excellent in terms of clarity, though the reference in the changelog to reducing red tint appears to have stripped too much red. It’s not terrible though.
However, when it comes to the rear camera, photos had realistic colours prior to the update, but became overly saturated following the update. Some of us want realistic colours by default. If we want overly saturated colours, we’d change the settings manually.
I also think that photos from the rear camera are too HDR-ish, both before and after the update.
While I think the selfie camera is really good, the rear camera needs tweaking to get it up to standard, and unfortunately, the recent update is a step backwards in terms of colours.
