random color noise spots on photos taken by the Lightroom mobile app on iphone 13 pro

Hello,

randomly some color noise spots appear on DNG photos taken by the mobile Lightroom app on my Iphone 13 pro in the HDR mode. A sample attached, the spot is in the lower left corder. I have never experienced this in the native app / nor in any other third party app. Anyone suffer the same issue, or know how to solve it ? Thank you!

This happens with "Auto" settings. You'll find it a lot with photos taken at night. It's because the auto settings algorithm is brightening that area beyond what is possible for the available light in the image. You will have to change the develop settings and back off some of the exposure, whites or highlights, especially in that area. 

This will affect your overall photo, so you will have to make some compromises. Perhaps you'll need to compensate by brightening other areas with a local adjustment. Or, you can creatively crop to remove some of the trouble areas.
