The Sony Xperia Z4 has yet to be released and we're guessing mobile carriers are already preparing for its coming. However, there is still the Xperia Z3 to deal with. In January, the smartphone together with the Xperia Z3 Compact, were rooted finally. We learned Android 5.0 Lollipop is coming to the Xperia Z2 and Xperia Z3 a few months after Sony played around with Lollipop AOSP on a Z3. A purple Xperia Z3 Purple Diamond Edition was also revealed after a limited edition series was announced earlier.
