The LG G3 has been using Android 5.0 Lollipop for a little while nowadays, but the same is not true for G3 S. this is the middle range handset that appears to be like G3, but with less specifications. It’s possibly the closest to a G3 Mini, as it were.
Apparently, LG didn’t forget about G3 S on the software. The company is working in progress to bring the Lollipop update to G3 S units, at least in Hungary.
Since, it is already in Hungary, it may be available for other European countries soon. After the update, the G3 S, runs Android 5.0.2 Lollipop and V20a software version.
Since Android 5.0 is just now making its way to G3 S, it’s not clear when of if this smartphone will receive the update to Android 5.1, or LG’s most recent UI overlay on top of Google’s OS.
