leaked screen shots of HTC's Sense 3.5 became leaked video footage. Purportedly running on the OEM's unreleased, ladies-only Bliss handset, XDA.cn has a hands-on of the Android-based UI that looks to be more of a refinement, than revolutionary update. So, what can we glimpse from this apparent sneak peek? The ROM, shown to be running atop Android 2.3.4, now sports a more pared-down look, as evinced by the lock screen's sleeker ring. There's still the same seven homescreens on offer, although it now appears you can delete the contents of a selected screen by dragging it to the trash. Gone is the familiar home panel with its curved shape, in favor of two non-intrusive, dedicated app and phone buttons on the left and right sides of the screen. The widgets also look to have taken on a roomier size, and the volume can now be controlled via an on-screen widget. Aside from those minor tweaks, not much else has changed, but you can definitely see an improvement in the UI's fluidity. Could this be HTC's very next upgrade to its popular Android skin, or are we looking at a slickly-produced ROM? You can judge for yourself in the video after the break.
