For Android development on real device like Samsung Galaxy S2, you need to install Samsung OEM driver or USB driver. This Android OEM driver documentation will guide you where to download it… but the guide is not easy to follow.

Actually, the “Samsung USB driver” is included in the software called “Samsung Kies or PC Sync“. The following guide will show you how and where to get it.

P.S This example is using Windows 7 and Samsung Galaxy S2.

1. Samsung Phone Model

Most Samsung websites ask about your phone model to download the software. The phone model number is available on the back of your phone, see figure below :
