Noticed recently my iPhone XR is taking horrible pictures. Outdoor photos are better. I'm assuming it's an issue with low light/high ISO. I think it's a hardware issue but wanted to share to see if anyone had any ideas on if there was a way to correct these in LR. As you can see, the photo is very noisy and also has, not sure what to call it, blockiness? artifacts? You can see the blocks/pixels on the wood floor how they are not smooth.

I especially notice this on photos of people. Their faces don't look right...almost like they were painted or smoothed out too much, and looks plasticy. In the face picture for example, it looks like more than noise. I just don't know what to call it or how to fix?

My first thought looking at the photo of the child is it was taken in "portrait" mode, a settings in the newer iPhones. I turned it off in my phone. The other issue, the blockiness, might be because of the resolution; for instance, if the image is simply too small to render well. Without having your phone in front of me, however, everything I've just written is conjecture! Hope it helps, anyway.

Thank you for the reply. I had thought about resolution as well but it’s really cranked high. I can apply noise reduction but then people look plastic-like and as for the floor, it’s just to pixelated

You might try shooting similar images in DNG using an app like ProCamera, and see if you have the same problem as with JPGs - so, for instance, it could be a matter of how the phone is compressing/processing the original image. Offhand, you might want to run some controlled tests to see how the phone acts under similar - and different circumstances - to see if it is a hardware problem, or just one of those things (which I've encountered, leading the conclusion that, for some photos, it's just one of those things...).

These artifacts lokks like a result of the jpeg compression. I think the compression level is too high. I don't know I-Phone, but there might be a pameters in the camera for the jpeg called something like "compression level" or "quality level". If so, try to change it to a lower compression or a better quality.
