I am with Telstra in Australia and I have an lg g3 running kitkat. My friend at school has the same phone and he has lollipop. For some reason there is no update for my phone to upgrade to lollipop please help
Is he on Telstra? And did he recently get the update? (They're parceled out slowly, so as to not overload the servers.)
You can always look in Settings/General/About device, to see if there's a Software updates line (it should be the first one) and try to update from there.
If not, look on XDA Forums for your submodel G3 to see if anyone has posted the update file.
