Earlier today, Sony has begun rolling out the Android 4.4.4 firmware update to their Xperia Z1 Compact handsets in Italy, Russia and Indonesia. This update comes with a build number 14.4.A.0.108.
Although we’re not sure about the file size for this update, but do make sure you’re connected to the WiFi before updating your device if you don’t wish to risk bursting your data usage.
So far Sony has yet to release the official changelogs for this update but we reckon its just some bug fixes as well as software optimizations for the Xperia Z1 Compact. Do share with us more about the update once you have it on your device!
