When i got my iphone 5 it was on ios 6.0.2 an everything worked just fine,but after a week or two my camera started terribly lagging,it was not so smooth like it used to be when taking pictures.If i go and take a picture when i move the phone a little bit it's very shaky and it's not how it used to be and HDR is turned off,when i go to another camera app it's the same problem!i updated my phone to ios 6.1 but the problem was still there,when i'm taking a picture the image on the screen is lagging and shaky i don't know what's the problem,please help me
