This happens more and more, I guess it's an unholy mix of "better compression as long as you don't actually look at the image" and "ai improvement".. A few weeks ago, I took a really lovely picture of my son, composition, facial expression, focus, light, it was _PERFECT_ except.. The algorithms in my phone had decided that it'd be better to scrape off his fucking skin and replace it with the texture of the wall behind him! Of course it must be my fault for buying such a cheap phone, it only a Galaxy 22 Ultra, I'm sure the 23 Ultra is better... But it was not out when I changed phones.. Wtf^wtf.. So I go turn on RAW so I can at least salvage picture in the future, except RAW only works in the "pro" camera mode which is inconvenient to use and sometimes it silently falls back to non-pro.. In the end I gave up and installed a third party camera application, I guess I just have to trust Mark, at least he hasn't actively messed up my photos. https://play.google.com/store/apps/details?id=net.sourceforge.opencamera https://play.google.com/store/apps/details?id=net.sourceforg...

I have a Samsung S23U and previously a S22U (and before that one plus) and I've never had that happen to any of my photos (and I take a lot). Hell, I don't think it's using computational photography besides basic denoising/lightening magic for low light (and their stupid moon replacement thing...they already beat Apple just having the 10x lens, no need for the moon bs). I think the default camera app is fine.

  Here's a photo taken by my S22U, http://dusted.dk/pages/computers/J-11/DEC_J-11_Gallery/full/2.jpg http://dusted.dk/pages/computers/J-11/DEC_J-11_Gallery/full/... that's a cardboard box on top of a matte PC case, but somehow the phone sees this strange blurred pattern in it, as if the phone was moving (which it was not) while at the same time, the label is artificially sharp (almost as if edge detection is taking place), at the same time, you can't see a single fiber of the cardboard box (except for the very edge where it looks like it's grown hair, which it has not).. Have you maybe looked close enough at your photos ?

    That's denoisimg, that's a low light image and with such a small sensor it has to denoise hard cause it's pushing that sensor hard. The white label may appear sharper because white reflects more light back...so higher contrast and less obvious noise. Contrast is good for denoising algos afaict, textured surfaces are horrendous cause...you can't tell what's noise in the texture so you just gotta do your best. Every phone will create shots like this in low light/indoors.
