Check for software and app updates

If you’ve completed the steps above, you should be all set to start using your Android TV. The first thing you want to do is check for software updates. To do this head to Settings (gear icon) > Device Preferences > About > System Update.

The latest Android TV version is Android 9 Pie. This should be the software running on most Android TVs right now. If you have a really old Android TV, it might still be stuck on Android 8.0 Oreo, however. If that’s the case, you’ll have to wait for your Android TV OEM to roll out the latest software version. Google has also announced the Android 10 and Android 11 updates for Android TV, but it could be ages before they start rolling out widely.

Just to give you some sense of how slow Android TV updates are rolled out, Android TVs only started getting Android 9 at the end of 2019. So, you can expect Android 10 to rollout sometime around the end of 2020, or even later.

App updates are also something you should check for when you first start using your Android TV. You will find several major streaming apps like Netflix, Amazon Prime Video, YouTube, and others, pre-installed on your Android TV. Before you start using them, you can check for app updates by heading to the Google Play Store on your Android TV.

The Play Store is located in the top row of your Android TV homepage. Alternatively, you can find it in the Apps channel on the left side of your home screen. To update all apps, select Google Play Store, then navigate to the My Apps section on top and click on Update All. To set apps on auto-update, head to the Settings (gear icon) withing Google Play Store > Auto-update apps > Auto-update apps at any time.
