Samsung has unveiled four new smartphones using the Android 2.3 Gingerbread mobile OS, including the Galaxy M Pro pictured above.

As one of Samsung's Pro handsets, which are aimed at business users, the Galaxy M Pro has a Qwerty keyboard. The device also comes with several other enterprise features including Cisco Mobile and Exchange ActiveSync for synchronising email, contacts, calendars and notes.

The Galaxy W, pictured above, has a 3.7-inch touchscreen and 1.4GHz processor.

The device, which will be pitched to the higher end of the market, features a five-megapixel rear camera with LED flash and a front-facing camera.

The handset also comes with Samsung's remote tracking system Kies Air so users can follow their phone if they misplace it.

The Galaxy Y comes with a three-inch touchscreen, a two-megapixel rear-facing camera and 160MB of internal memory.

Users will be able to take advantage of Samsung's Social Hub feature, where users can keep in touch with their contacts from various social media sites in one place.

The Galaxy Y is pitched as an entry-level device and will be released in a variety of colours.

The Galaxy Y Pro, shown above, has a 2.6-inch LCD screen and a rear-facing three-megapixel camera.

The Galaxy Y Pro comes with Samsung's ThinkFree mobile office feature which enables a variety of Office documents to be edited on the handset including Excel, Powerpoint and Word.

Like the Galaxy Y, the Galaxy Y Pro is designed as an entry-level device, but for business users.
