Tizen Indonesia posted a couple of interface screenshots of upcoming Tizen devices. The screenshots are looking quite clean with some business tint to it. Samsung is having plans to introduce their first Tizen devices later this year. Samsung wants to battle Firefox OS with Tizen OS. Tizen OS is a project by Intel and Samsung based on HTML5. Tizen announced a couple of weeks ago Tizen 2.1 Tizen 2.1 is a public release version so we will hear and know more about Tizen later this year.
According to Samsung is a good interface no interface which means it must be very easy to use. Since Samsung brought their Nature UX interface on the Galaxy S3 many customers didn't switch to custom roms. Touch Wiz Nature UX is lots better than Samsung's first skins. We expect the first Tizen devices to be very smooth and easy to use.
See below the screenshots of messages, camera, and internet. Cause Samsung didn't unveil any Tizen product yet please keep the screenshots with a pinch of salt.
