Some phone makers like Sony Corp has announced a lineup of smartphones that will receive the Android 4.3 update soon, these includes  Xperia Z, Xperia ZR, Xperia ZL, Xperia SP, Xperia Tablet Z, and the newly launched Xperia Z Ultra.

    Doesn’t look great on my opinion! 4.2 was a failure to begin with. Multiple pages on lockscreen? God. Only good thing about 4.2 is toggles on top bar in separate page (miui had it in gingerbread :p).
