I have a Moto X 1st gen running Android 4.4.4. When I go to System updates, it says "System update available" but when I select that it says "Your device's software is up to date". It has done this for the past several months. I know that Android 5 (Lollipop) has been released for the Moto X and was expecting it to show up as an update on my phone, and I believe that's what System updates is telling. But the phone isn't getting the update. How do I force the phone to get the pending update? I really don't want to do a factory data reset if it can be avoided.
