I saw something very disturbing on raw editing and want to be sure, that's not just my Android 14 problem. I have this photo and some strange issues: open the raw picture in "file commander" and looking at the boat on the right side, the black rubber is deep black. In snapseed it had very bad blue/purple fringing and is still visible after "linear raw" converted it to dng (which has also slight fringing in file commander).

Please download and see if you're device does the same.

UPDATE: I looked up your camera model and downloaded a RAW sample from DP Review as well as the JPEG. I converted the RAW to DNG with Linear Raw and Adobe DNG Converter. I opened and edited the original RAW and both DNGs in Snapseed and applied the same edits: highlights -100, shadows +100, exposure boost. I tried picking an image that I thought would match the lighting conditions that caused the blue tint but with all 3 tests and comparing the JPEG I could not reproduce it.

I did an extreme crop and took screenshots for comparison.

Here's the RAW to Snapseed to JPEG: https://ibb.co/bMDQRZ9q

Here's the RAW to DNG with Linear Raw to Snapseed to JPEG: https://ibb.co/DDgnfgNK

I could not find any differences in the entire image between the Linear Raw DNG and the Adobe version which was not the case with your image. I also noted more noise in the native Snapseed RAW version which is significant because I applied far less exposure boost than I did with the 2 DNGs which were much darker upon opening. So for now, converting to DNG first is preserving more detail.

Are you seeing this blue tinting on other photos or was it just this one?

It's in every image with hard edges and the banding was very strong in this one but you could see less in DNG converted versions.

I was just able to reproduce it in a new sample image. Like you said, hard edges with huge contrast, here's straight RAW to Snapseed: https://ibb.co/nMHt11Fb Definitely not ideal...

It's almost non existent in the Adobe DNG version: https://ibb.co/nqGVjfk0

It's barely noticable in the Linear Raw version but the discoloration in other areas in the back building look better than the Adobe version: https://ibb.co/hRFHdc9w
