Sony Mobile has just announced that Android 5.1 Lollipop will start rolling
to all of the Xperia Z series as well as the Xperia C3 and T2 Ultra from July
2015. Xperia M2 and Xperia M2 Aqua owners will finally not be left out in the
cold – Sony has officially confirmed that these handsets will be upgraded
directly to Android 5.1, which is fantastic news. The update for the Xperia
M2 series will start after Android 5.1 has rolled to the Xperia Z series, but
we’re not sure M2 owners will mind given this very good news.
简单 google 翻译：
官方：从七月开始
所有 Xperia Z 系列 包括 C3 T2U M2 都将升上 Android 5.1
简直是太佛心了
