When it comes to receiving latest Android updates, the users with carrier locked phones always lags behind. The reason for this is that the software for such has to go through some additional testings which are from Carrier. So is issue with T-Mobile Xperia Z1s and Xperia Z3 users!
While all the other variants of Xperia Z1 and Z3 have already received the Android 5.0.2 Lollipop firmwares from Sony, these two unlucky handsets are still running on older OS. But there’s a good news! We have been reported that T-Mobile and Sony are working on bringing the Android 5.0.2 Lollipop firmware update to Xperia Z1s and Xperia Z3 with build number 14.5.B.0.228 sooner than later.
Earlier this week, Sony rolled out 23.2.A.1.62 Android 5.0.2 Lollipop firmware for Xperia Z3 unlocked version and 23.1.A.1.28 Android 5.0.2 for Xperia Z2 D6503. Although there are no dates given but we hope Sony and T-Mobile will make it faster to surprise their loyal users. Stay tuned with Androids DNA for more updates!
