Yes I can. Had an S2 before I sold it about a year ago and I bought two S4 mini's within the last month for my girl and my sister. The time I spent with their phone's downloading apps and setting it up for them, it seemed very smooth and snappy. As a matter of fact, when I was in the store purchasing the one for my sister the sales rep while she was demonstrating the phone remarked how well the phone ran and to her it seemed snapper the the S4!! Not sure about the S4 part but from what i can remember from my S2, the mini is a better performer and while the screen is about the same size the actual phone is smaller. The only complaint I have is with the meagre storage. It should definitely have more. But I got both of them and SD card so its ok i guess.
