Processing images for my Xiaomi Mi Note 10 is a mess. It is not possible to use the color temperature slider to get useable results. It gets not warmer or colder but gets a purple or green tint. If there is a grey spot in the image I can use the color picker for white balancing, but this is not always the case. I am using Lightroom Classic 9.14. Luminar and other RAW processors (e.g. RawTherapee, Cyberlink PhotoDirector) do not show this issue.
If I use GCam (Google Camera port) DNGs from the same phone I have no issues.
Looks like a bug. The white balance values in this file are extreme which is probably due to a bad built-in profile in the dng. Post it at https://feedback.photoshop.com. Here we are just other users and can't help fix bugs.
as far as I unserstand a DNG file is a standard and all of them should be supported by the Adobe RAW Converter/Processor. The images are opened correctly and processed correctly, except the color temperature correction.
All other RAW processors I have tested (RawTherapee, Cyberlink PhotoDirector, Snapseed) have been able to process images form the Xiaomi Mi Note 10 without any issues. Only Lightroom has a problem when using the color temperature slider.
The link to the DNG is a native RAW/DNG from the stock app from the phone.
As I mentioned I also use GCam on this device and the generated RAW/DNGs from this app do not have this issue.
