notably, Sony changed essentially the entire interface seen in it’s
Gingerbread and ICS predecessors by allowing users to swipe up or down
anywhere to unlock the phone. Upon contact, the screen breaks up into an
effect reminiscent of Venetian blinds, which lasts for as long as you
hold your finger on the screen. This serves to make unlocking your phone
easier than before by freeing your thumbs from awkward motions. There
is now also an option to change the background of the lock screen with
the default wallpapers or your own pictures through the Album
application. Swiping the digital clock to the right allows access to
various music shortcuts, and swiping to the left is a ‘quick-capture’
camera feature, where a picture is taken upon swipe. Unfortunately, lock
screen notifications such as new text messages and emails have been
removed by Sony, justified by the pull-down notification area of the
status bar.
Works on all ICS roms which supports ICS xperia lockscreen.
Minimum RAM usage is 2,5 MB (If you choose image from Xperia Wallpapers -
probably will be 15 MB) and unfortunately no swipe notifications.
Thanks to SpaceCaker for his helps and other testers.
