Since I still do not have my blue Galaxy S3, I of course can not say whether the case fits exactly. But it is well finished and closed back. So no dirt comes into the camera. If you want to use this, the sleeve can be easily fold back without having to take the phone out of the case. Just a shell I was looking for, because I so one had for my S2. A little odor has the envelope unfortunately. I hope that's gone in a few days and I have my S3 hopefully. I will then give a quick update.
