My Xperia z camera seems to have lost the color noise reduction. Everytime I shot a subject in mid light condition the photo result full of colored noise. I don't know why, the phone is new and until recently, the problem would not show up. I attach a photo to show you what I mean.
try lowering the ISO when taking pictures since it appears to be a issue with iso being set to AUTO which then sets ISO allways to 1600 or w.e max amount is now
