I just upgraded to an iPhone 5 from a 4s and Ive noticed in darker lighting the iphone 5 will give you a brighter picture but with much more grain. I have a bunch of pictures with my 4s and they all look superb especially outdoors. With my iPhone 5 I find the noise in the picture is quite annoying especially in lower lighting. I think it has to do with the fact that the iPhone 5 has a higher ISO than 4s/5s therefore more grain in lower light. I really find it annoying and wish there was an app to adjust that. Did anyone notice this? Im sure its been discussed before but now that Ive just picked up two iPones 5's I'm noticing the grain especially when I take pictures indoors and its quite annoying I dont want a murky noisy picture. I really think I prefer the 4s. Or is there any chance I picked up two defective iPhone 5's?
