If you have a smartphone or tablet from the Sony Xperia Z family, you’re guaranteed an Android 5.0 Lollipop upgrade no matter how old your device. Sony has vowed to upgrade all Xperia Z devices — including the original Xperia Z, the Xperia ZL, the Xperia ZR, and of course, the new Xperia Z3.

“We’ll be making Sony Mobile’s Android “L” upgrade available for the entire premium Z series,” the Japanese company confirmed in a post on its blog. If your handset is called the Xperia Z-something, then, you’re getting an update. But to be sure, here’s the full list of devices that are eligible:

• Xperia Z
• Xperia ZL
• Xperia ZR
• Xperia Tablet Z
• Xperia Z1
• Xperia Z1s
• Xperia Z Ultra
• Xperia Z Ultra Google Play Edition
• Xperia Z1 Compact
• Xperia Z2
• Xperia Z2 Tablet
• Xperia Z3
• Xperia Z3v
• Xperia Z3 Compact
• Xperia Z3 Tablet Compact

The Xperia Z Ultra Google Play Edition is first in line to get the update — and that’s hardly surprising given that it runs pure Android and needs no tweaking. From then on, Lollipop will be rolled out to devices based on their age, beginning with the newest first.

“We’ll start the upgrade at beginning of 2015 for the core Xperia Z3 and Xperia Z2 series,” Sony says, “continuing thereafter for all remaining devices above.”
