I've posted an article about the availability of Samsung Galaxy S3 Mini early last year.
Now i have a friend who bought one ( used phone) to replace his aging Alcatel smart phone. Borrowed his phone and then took a picture of it.
Actually, you'd be surprised if you hear how and why my friend bought this thing.
iPhone 5s on top, s3 mini on the middle and 4s below. S3 mini is thicker than the two iphones
If you dont compare the S3 mini's screen to other phones you wont know that it has a 4" display.
