After rolling out the Android Marshmallow update to G4 owners in Poland and South Korea, LG is now seeding the update to customers across Europe.
The official Android 6.0 Marshmallow update for unbranded LG G4 h815 models across Europe is rolled out through LG’s Bridge computer application. In order to get the update you will simply need to connect your phone to computer via USB cable and launch the LG Bridge application.
However, the update is only being pushed to the LG G4 LH815 variant, so you shouldn’t expect to receive an update if you own a different G4 model.
