New Sony Xperia Z1s Android 4.4.4 Update Is Now Being Pushed to T-Mobile Users

If you happen to own a Sony Xperia Z1s from T-Mobile you should keep an eye on the notifications bar. T-Mobile has officially announced that a new Sony Xperia Z1s Android 4.4.4 update is now being pushed to the users over-the-air.

According to the Sony Xperia Z1 Android 4.4.4 update changelog posted on T-Mobile’s support page, the new update arrives with WiFi-calling enhancements, better system stability, along with Camera and Bluetooth improvements. Besides all these enhancements, the new update also adds a new feature: T-Mobile Free Inflight Texting support.

As usual, the new Android 4.4.4 update for T-Mobile Sony Xperia Z1s is being rolled out in phases, which means that some of you might not be able to download and install it right away. Once your smartphone becomes eligible to receive the new firmware, you should be able to notice a system update message in the notifications bar. Tap on it then follow the on-screen instructions. In case the system update notification failed to appear, you would also want to perform a manual check under All apps > Update Center > System > Check for updates. Alternatively you can grab the USB cable, connect your Z1s to the PC and check for the update via the Sony PC Companion app.

It’s also worth noting that the new firmware will update your system version to 14.4.B.0.56. Because we are dealing with a minor system update, the update file shouldn’t be too big. Anyway, we are recommending you to use a WiFi network while downloading the update in order to avoid unwanted data charges.
