After having already released the Wave handset on its proprietary Bada operating system earlier this year, Samsung has now announced its second Bada smartphone – the Samsung Wave 723.

The Wave 723, which marks Samsung’s efforts to stick with its own open-source OS, will probably be released by the end of September.

The key features of the new Wave handset, which will use the Bada SDK 1.1, include: a 3.2-inch TFT-LCD screen; apps front loaded on the GUI; support for 802.11n wireless connectivity; Bluetooth 2.1; A-GPS; an accelerometer; and a USB port. The 5-megapixel camera of the forthcoming Wave will be capable of recording 320 x 240 resolution video.

The Samsung Wave 723 will also boast instant access to Facebook and the user’s contacts address book, with the Social Hub being its one stop shop for social networking management.

With the Bada SDK 1.1 of the Wave 723 to allow developers to use 1.1 Auto-UI scaling, Simon Stanford, chief of Samsung Mobile in the UK, said that the handset will provide the developers with “new opportunities for the creation of apps.”

About the Wave 723 – which early reviews are terming as a serious contender in the smartphone arena -, Stanford further added: “The launch of this device clearly underlines our commitment to smartphone products on different platforms and forms part of our strategy to deliver a wide range of handsets designed to suit a multitude of users.”
