Overall, it’s not a drastic departure from version 3.0 that’s featured on devices like the HTC EVO 3D and Sensation 4G. In fact, it’s a little bit more simplified in layout with its sprinkling of some fancy looking lock screens and transition effects. Furthermore, the other noticeable difference is the omission of the previous launcher bar sitting at the bottom of the homecreen, and instead, we’re presented with two different buttons to access the app tray and phone dialer. Also, we find a new process in configuring the various homescreens available.
All in all, it’s not too much of a dramatic jump, especially considering that the new experience is expected to become available on a wide-array of HTC smartphones consisting of low-end models as well. Equally at the same time, we get to spend a teeny tiny amount of time with the upcoming HTC Bliss.
