Long time ago when I seen stock Android 4 soft keys at first time I think “I love it!”. And now after 5 years they stay so awesome and hots. But how we know Sony replace stock Google keys by their own and many people did’t use them.
I have tried to save original colors combination and graphics elements. As a result, we can see interesting mix of newest and older Android versions.
