Sony Android Concept ROM for Xperia Z3 (Download & Install FTF)

Sony is testing a new user interface to use on Xperia devices. Until now, we are used to seeing a similar user interface to stock Android on Xperia phones, with a few modifications here and there from Sony. Now, the company is testing a completely new ROM and calls it Sony’s Android™ Concept. This is a new ROM with a redesigned graphical UI. Sony has chosen 500 Sony Xperia Z3 users to download and test the ROM.

If you are a Sony Xperia Z3 enthusiast and want to test the new Sony ROM but didn’t get chosen, recognized contributor Jozinek has released the ROM for the public. The ROM is based on Android 5.1.1 Lollipop and it is very similar to a stock AOSP Android ROM, such as CyanogenMod.

Sony’s Android Concept ROM is very fast and stable. It is a stock Android ROM with Sony features. This build does not include Stamina Mode, XPERIA themes or Screen recording but it does come with Music, Album and What’s New.
