Update to Android 5.0 Lollipop on Nexus 7 I currently own a Nexus 7 (2013) device, but after updating the OS several times, I am stuck at Android 4.4.4. I know that Android 5.0 Lollipop has been released for the Nexus 7, but I don't know why I can't download it.

Is there a way for me to download it without sideloading/factory imaging my device?
First of all, you get updates to your device from google on the basis of the date on which you bought the device. That is if you bought a tab 5 months ago and one yesterday the one which was bought earlier will receive update first. So don't worry when you have upgrade chance you will be notified.

Did your tab notified you that you have a upgrade available?
If yes did you actually download the upgrade for 5.0?
