If you bought a Samsung Galaxy S4 I9506 – aka S4 LTE-A or S4 LTE+ - you may have been feeling a little left out of the Lollipop update bonanza.
This version of the phone has a Snapdragon 800 chipset, just like the Galaxy Note 3 and an update over the Snapdragon 600 in the I9505. Most of its siblings got Android 5.0 – the Google Play Edition and Exynos versions of the Galaxy S4, the Galaxy Note 3 as well.
Anyway, the update is finally available – for SIM-free devices in Slovakia and the Czech Republic, plus Vodafone handsets in Germany and the Czech Republic. The China Unicom version of the Galaxy S4 LTE-A G9006 is being updated too.
The firmware is a heavy one – 1.2GB for the European phones. The exact version those phones are receiving is Android 5.0.1, build I9506XXUDOA6, while the China Unicom software is Android 5.0, build G9006WZNU1BOA4.
You can download these files to manually flash your Galaxy S4 LTE-A though that's for advanced users (make sure to back up your data first!). Hit the source link for download links, but proceed at your own risk – it's safer to wait for the OTA update to arrive in your region.
This only leaves the TouchWiz version of the Snapdragon 600-based Galaxy S4 with no Lollipop.
