The cover fits perfectly. All recesses agree (even the USB plug goes well in). One has the S3 also securely in your hand with this envelope. BUT: The On / Off button - and the volume button can be very bad use. A pressure point you can not feel absolutely. The keys are also not to feel. Have now settled again the shell, because I want to serve my S3 also. Too bad, I liked the look. On my Galaxy S4 I have the same envelope. But everything works great. Why not the S3?
