It seems to be only for Xperia with 4.2+, and by the moment its confirmed for Z's family at least, someone with the 4.3 leaked can confirm if its available for T and V?
If google play dont let you install on T and V there is some way to made it work without installing Z1's camera mod? I supose maybe only need to install Z1's framework and get the .apk
Thanks to the one who test it, I have the V since a week ago, but im trying to calibrate the battery so i prefer dont be flashing 4.3 by the moment
