Samsung has released three smartphone models that run on its own operating system. The Wave series models backed by Samsung's proprietary system "Bada" is being seen as a move away from becoming dependent on Android.

The Wave 3 has a 4-inch AMOLED screen and a 5 megapixel camera. The Wave M will have Samsung's first instant messaging tool chatON installed and entry-level Wave Y with 3.2-inch display. They will all be in the shops by October. The three models add to 7 Wave series lineups Samsung introduced since first Bada-based product went on sale in May 2010.

Samsung crawled to the top of the smartphone pile behind Apple on the back of its flagship Android-based Galaxy S models. Now it is focusing on emerging markets with cheaper phones costing $200 or below. Last week Samsung unveiled four new mid-to-low end models running on Android to defend its market share. The Wave series will allow access to Samsung Apps, which has around 13,000 applications.
