It's been a while since Android Lollipop was unveiled, but a lot of your handsets still don't have it, as it's down to individual manufacturers to bring it to their devices.
That takes time, but we're finally seeing it trickle out to ever more phones, and many manufacturers have also revealed when they plan to roll out the update.
We're constantly updating this article as new information emerges so read on for details about your specific device and manufacturer and remember to check back regularly.
The good news though is that if you don't have Lollipop for your phone yet you probably will soon. And the even better news: it's worth the wait, as it includes a smorgasbord of new features, a visual overhaul and numerous under-the-hood improvements to make if faster, more efficient and lighter on your battery.
- Read our hands on: Android 5.0 Lollipop review
Latest update: Sony has begun rolling out Android 5.0 Lollipop to its Xperia Z3 handsets, and OnePlus One owners will soon get the Android 5.0.1-based Cyanogen OS 12 update.
One of the best things about buying a Nexus device is that they're first in line for software updates. As such not only did the Nexus 6 and Nexus 9 ship with Android 5.0 Lollipop, but it's since been rolled out to the Nexus 5, Nexus 4, Nexus 7 Wi-Fi (both the 2012 and 2013 versions) and the Nexus 10.
That's most of the remotely recent Nexus devices accounted for, but it does leave a big question mark against the cellular versions of the Nexus 7 2012 and 2013. Those tablets should see an update at some time, though Google has not indicated when this will be.
Any Nexus devices older than the ones we've already mentioned are all but guaranteed not to get it, meaning that Nexus S owners are plum out of luck. Google has also confirmed that the Galaxy Nexus will not receive the update.
HTC has been more forthcoming with its update plans than some manufacturers and it's no surprise given how quickly it's started bringing the update to users. In a statement the company originally said:
"We will begin rolling out updates to the HTC One M8 and HTC One M7 in regions worldwide within 90 days of receiving final software from Google, followed shortly thereafter by other One family members and select devices."
HTC has made good on its promise for some users, but not for others. The Google Play Edition of the HTC One M7 has got the update, while unlocked and developer versions of the HTC One M8 worldwide and the HTC One M7 in the US have now been given a lick of Lollipop too.
But owners who have a device that's tied to a specific mobile network or those with a One M7 outside the US may have to hold on for a little while longer.
We're going to assume that most other HTC handsets released in the last 12-18 months will also get Lollipop at some point given HTC's commitment to the upgrade cause.
Another leak states the HTC One Mini 2 and Desire 816 will get Lollipop sometime in March or April, while the HTC One Max, HTC One Mini and Butterfly S have an expected Android 5.0 rollout of March-May.
Samsung started rolling out Android 5.0 to the Galaxy S5 in mid-January, so most if not all S5 handsets should have it by now.
The Android 5.0 update for Samsung's Galaxy S4 handset is now live for owners in India, so we should expect S4 smartphones in other parts of the world to get the update soon. You'll be able to download the 1GB update OTA (over the air) or through the Samsung Kies desktop software.
Russian users of the Galaxy S4 should also be able to grab the update, while various European countries are seeing the update land on the Galaxy S4 LTE-A.
The Samsung Galaxy Note Edge is now also getting the update to Android 5.0 Lollipop, though it's heading to lucky owners in Australia first. The update will be 1.02GB large, so make sure you're on Wi-Fi when you download, and Samsung notes you'll need 3GB of free space.
Hopefully owners of the Galaxy Note Edge in other parts of the world won't have long to wait to get the update.
Owners of unlocked Note 4s in South Korea and Poland are now able to get the update by connecting to a Wi-Fi network, opening up Settings, selecting 'About Device' and tapping on 'Update Now' under the Software Update option.
To whet your appetite before it lands it looks like photos of the Samsung Galaxy Note 4 running Android 5.0 Lollipop have leaked on to the internet.
The Galaxy Alpha is also likely to get the update soon, according to Danny Dorresteijn, the co-founder of respected fan site SamMobile.
Other Samsung handsets may have to wait a little longer, although we'd expect that most high profile devices released in the last 18 months to 2 years will get the update, including the Galaxy S4 Mini and the Galaxy S5 Mini.
We doubt that the Samsung Galaxy S3 or anything older will get Android Lollipop. It's a device that's already over two years old and some versions of it didn't even get Android 4.4.
Samsung doesn't seem great at updating its tablets either. There's a good chance recent slates like its Note Pro and Tab S ranges and even the Samsung Galaxy Note 10.1 2014 will get Android Lollipop, but anything older or low end is probably not going to happen.
Sony has openly declared that it will be "bringing Android 5.0 Lollipop to the entire Xperia Z Series."
It's even published a full list of handsets which are in line for Android Lollipop, and the Sony Xperia Z Ultra Google Play Edition has already received the update.
Sony started rolling out the Android 5.0 Lollipop upgrade for the Xperia Z3 and the Xperia Z3 Compact on March 16. Owners in the Nordics and Baltics regions will be the first to see the update, with other markets getting it soon after.
Sony also announced that the rest of the Xperia Z series will get the update in around two weeks, so keep an eye out to see if your device has an update waiting.
