Thanks to Yash aka @Alsiladka and his friend who have shared the awesome looking Nokia Belle FP2 UI Video. According to this video the Nokia Belle FP2 comes with Swipe to Unlock lockscreen, New keyboard layout with predictions, new music player, music player shortcut in notification bar and much more. Have a look at the video below.
Cant wait for the update to reach my PureView. The keyboard looks better than the one we have. Thanks Yash.
