iphone 5 camera is grainy
I just realized that the camera on my iPhone 5 is taking really horrible pictures. I kept thinking it was the lighting I was in, but after shooting pics in different lighting, they are all very grainy and blurry. I tried cleaning the lense and taking my case off and I still get bad pictures. Just for the fun of it, I took my old iPhone 3g and took some pictures to compare. It was doing a much better job. I also tested my 5 against my boss' 4s and his blew it out of the water. Is there an issue that I'm not aware of? Did an update mess up my camera? My phone is about 6 months old and it seemed to take good pictures before. I am partly asking this because my brother has the same problem with his brand new 5c. He bought it to replace an S3 and he is very disappointed with the 5c's camera. I was the one that talked him into switching to Apple. Please help. Thanks.
