I have both a Moto X (1st gen) and a Moto X (2nd Gen) in our family. When will Android L be pushed to these devices by Verizon ?
Nothing official has been announced yet, other than that the phones will be updated.
And that announcement came from Motorola and not Verizon Wireless.
The Moto X (2nd Gen.) began rolling out on 11/24. Go into Settings>About Phone>System updates. The 1st Gen Lollipop update has not rolled out yet.
