Nowadays there seems to be a rage of porting MIUI GB themes to MIUI V4. “Pieces of Paper V4” is another GB theme that has been ported by its original author zyj123911. The theme looks very simple and light. It has a very nice lockscreen with a n even nicer slider. The icons are good as well. Since it is a light theme, you will not find any visibility bus as seen in the dark themes.
The original theme is in Chinese. There were Chinese texts on the lockscreen, and on the dialer buttons in contact and phone app, so I had to modify the theme so that it does not seem awkward to an English user.
