To start, you'll need to check if your tablet is eligible for an update - just head to the settings menu and click on "About Device" to find out. If you're good to go, you can download the latest software update and follow the prompts to install it. It's like getting a brand new tablet, but without the hefty price tag!
The update process is pretty straightforward, but make sure you've got a decent Wi-Fi connection and that your tablet is fully charged before you begin. You don't want your update to get stuck halfway through, that's just frustrating! Once it's all done, you'll be rocking the latest Android operating system and all its awesome features.
