Samsung has shipped a new Linux-based smartphone in China. The SCH-i819 targets Chinese business travelers, and is the first Linux phone to support dual-band cellular operation with both CDMA 1x (800MHz) and dual-band GSM (900/1800MHz) networks, according to Mizi Research, which supplied the phone's Linux stack.

The SCH-i819 appears to share the same "slider" hardware platform as the SGH-i858, a tri-band GSM phone that has already been submitted to the FCC to be approved for potential US distribution.

Hardware specifications

The phone functions of the SCH-i819 run on a Qualcomm MSM6300 communications processor, said to comply with CDMA2000 1X Revision A, GSM release 99 phase 2, GPRS class B multislot class 10, and GPS (global positioning system). The MSM6300 is based on an ARM926EJ-S core with memory management unit (MMU), and integrates dual QDSP4000 DSPs, along with a Jazelle Java accelerator. It runs Java and Brew, Qualcomm's proprietary mobile applications environment.

The applications processing side of the SCH-i819 runs Linux on an Intel PXA270 applications processor clocked at 416MHz.

The SCH-i819 has a total of 64MB of SDRAM, and 128MB of Flash, although how these amounts are divided between the two processing subsystems is not clear. User file storage is expandable through a micro-SD TransFlash card slot.

The SCH-i819 has a 2.4-inch, QVGA (240 x 320) color TFT touchscreen display with 65K colors, and a 2 megapixel CCD (charge-coupled device) digital camera. Networking options include Bluetooth, IrDA, and USB.

The SCH-i819 has an 1100 mAh battery, and measures 4.2 x 2 x 0.9 inches (107 x 52 x 22mm).

On the software side, the SCH-i819 runs Prizm 2.5, a Linux-based smartphone operating system stack developed by Mizi Research; refer to this story about the launch of Prizm 2.5 for more details.
