Now that Google’s Holo theme has been around for quite a while now, it’s probably safe to say that a very large portion of apps, if not the majority, have adopted the Holo look. But as OEMs are, they like to keep things their way, and this is no different when it comes to Sony. But unlike some OEMs and their preferred interfaces, the aesthetic route Sony has taken doesn’t stray too much from Holo. This may have resulted many folks taking a liking for Sony’s UI, leading to XDA Recognized Themer BDFreak creating an interesting framework for the Sony Xperia Z1, Z, ZL, SP, T, TX and V.
As Xperia owners would know, the Sony UI can only be seen on apps made by Sony, such as the messaging app, Walkman, and the calendar. What this framework does however, is force the Sony UI to replace the UI of any non-Sony app, making the Sony look consistent throughout your phone. No matter which app you have installed, and what sort of theme they have, be it Holo or something made in MS Paint, the framework replaces every UI element with those of Sony.
If you’re unsure or wary of how this might turn out, BDFreak has provided some side-by-side comparisons of apps’ interfaces before and after installation of the framework to help you decide before diving in. Installation is very simple, merely consisting of downloading the appropriate zip file and flashing it through a custom recovery. There are also convenient zip files which revert everything back to they way they were before if you don’t like what you see.
