HTC patents 3 new ways of screen unlocking. First one is similar to the way that was used previously in the first version of TouchFlo on the original HTC Touch. The essence of the method is unblocking the screen with vertically holding your finger on the outer edge of the display. This might seem rather attractive for the users.
The second way is to provide a way of changing the locked screen saver without having to exit the lock. This method has been previously used neither by HTC, nor by any of its competitors and it’s rather compatible for now.
But the third way to unlock the screen is used quite often on devices of almost all the leading manufacturers, especially on smartphones with touch screen. It is so typical that the fact that previously no one has ever patented it can cause a genuine surprise.
