After Nokia's release of four phones into the entry-level market, Samsung leaked three of these devices, and it seems that it happened at the same event the Samsung L870, U800, and i900 were spotted.

Two of these phones, namely the Samsung B510 and B300, have CSTN displays, which are cheap displays with lower image quality and response rate that LCD TFT.

Little we know about the device, the only information we have is the following:

• Triband GPRS
• Stereo FM Radio
• Bluetooth v1.2
• No camera
• No information on memory capacity
• CSTN display with 65k colours
• Dimensions: 95 x 46.5 x 18.1 mm

The B300 has a clamshell form factor, and possesses a monochrome display and a colour display, So I'm supposing the outer display is black and white, and the inner display is the CSTN 65k screen.

Other features as reported:

• Dualband
• Dimensions: 87 x 45 x 18.6 mm
• No information about memory or MP3 support

The best of them all is the Samsung M620, possessing a VGA camera, FM Radio, and Stereo Bluetooth, which I presume is Bluetooth v2.0 with A2DP. This devices clearly reminds me of the E250.

According to reports, some of the features included are:

• 262k colour LCD display
• Triband
• slider form factor
• Probable MP3 player
