Sony Xperia Z1s firmware certification could be Android 4.4 update


The Android 4.4 KitKat update is still making its way to various devices and there has been talk of the update arriving for the Sony Xperia Z1s for some time. Now there’s some further hope as the Sony Xperia Z1s has new firmware certification, and it’s thought that this could be for the Android 4.4 update.

The Xperia Z1s is still using Android 4.3 Jelly Bean that it launched with, and we first heard indications of Android 4.4 for the Xperia Z1s for T-Mobile in April. At that time there had been PTCRB certification for firmware build 14.3.D.0.183 for model number C6916, and as this was a notable progression from build 14.2.C.0.159 it looked as though this could be the KitKat update.

However, the build that had been certified never appeared for the Xperia Z1s, but a new build has now been through PTCRB certification. This is firmware build 14.4.B.0.20, taking us from 14.2.x to 14.3.x to 14.4.x, looking like a significant update that implies KitKat.

We’ll keep you informed on the progress of this update for the Sony Xperia Z1s and we hope to bring you more news on it before too much longer. Are you waiting for the KitKat update for your Sony Xperia Z1s?

    Yes. Tired of waiting. All of the other versions that were capable of getting the update have gotten it. The Z1, Z1 Compact, and the Z Ultra are on 4.4.4. We still have the intermittent touch screen issue that is supposed to be fixed with the Kitkat update.
