Google has released the latest version (5.0) of its Android operating system, called Lollipop. This update is only rolling out to Google Nexus devices at the moment. There are two ways you can upgrade your device to the latest version. One way is to update manually To do this, tap Settings, ‘About device’, ‘System updates’ and then ‘Check now’. If an update is available, you’ll be prompted to download it.

The other way is what’s known as an OTA update. Because Android doesn't roll out its updates to all users at the same time (unlike Apple), you’re more likely to receive Android 5.0 as an OTA update. This stands for ‘over the air’ update, meaning you'll see a message in your notification panel when the update is ready to be downloaded and installed. Tap the message, then tap Download. Make sure you’re connected to a Wi-Fi network because the update file is quite large (around 480MB). After the download finishes, tap ‘Restart&install’. You’ll need to wait another 15-20 minutes while your device restarts and apps are updated for the new operating system.
