Earlier this year, Samsung retired Bada in support of Tizen. But Tizen phone is not officially declared. In developer documentation for Tizen, Samsung I8805 Redwood and I8800 Meliu has been showed up unofficially.
The Melius is a mid-range with 3G whereas the Redwood is a high-end device with 4G LTE connectivity. Both will run on the latest Tizen OS version 2.1, codenamed Magnolia.
According to Samsung VP,” the Tizen phone will be out in August or September, and this will be in the high-end category. The device will be the best product equipped with the best specifications.” This is most probably the I8805 Redwood. As per the rumours, the phone will be unveiled in the US initially and then in Europe.
