The upcoming update to the mobile Nokia OS, carrying the codename "Carla", shows up in screenshot form. The screenshots don't show much, however, you can get a taste of what the update is going to bring.
First, there's the new on-screen qwerty keybord, which seems to have been inspired by its Windows Phone cousin. The Nokia Browser has also been updated to a new version, which features some new UI improvements.
But the most noticeable change comes from the lock screen. Gone is the classic Unlock Button, and replacing it is a Swipe to unlock method. The user interface of the Music player also sees some improvements in the form of a refreshed UI, as does the Options screen, which borrows the looks of the Meego Harmattan UI.
The Nokia Carla OS update is reportedly destined for the Nokia 700, 701, 603 and the Nokia 808 Pureview. Unfortunately, the update won't be coming for the 1st generation Symbian^3 phones such as the Nokia N8, E7, C7 and C6-01.
