In contrast with other dual sim Samsung models, this phone is a part of the high-end "S" series, this is why it is marketed as a part of the "''Galaxy S'' family.

The phone also comes with Android 4.0.4 Ice Cream Sandwich, along with Samsung's proprietary Touchwiz interface.

Optionally, it can receive two calls simultaneously, but this requires divert-on-busy to be set up on each number and is subject to availability from the carrier and may incur additional charges.

A limitation of the Galaxy S Duos is that only one SIM can be active on UMTS (and therefore data) at a time and so it may be unsuitable for certain combinations of networks.

China Unicom offers the Galaxy S Duos as the GT-S7562i, which is essentially the same phone as the international version, and a variant called the GT-S7562C which omits the proximity sensor.
