TeamViewer is an indispensable tool in just about every tech support arsenal. It has been around for years on a variety of platforms including Android. Although you don’t get PC-esque functionality in the Android version, it is enough to help guide a less-tech-savvy person through something as ‘complex’ as changing notification settings. TeamViewer just added support for Android TV, and even without full remote control, TeamViewer adds some handy features to your TV box. The changes come via the latest version of the app with the following changelog

The new Android TV support comes by way of the updated TeamViewer Host app. To get started, hop over to the Play Store, install the TeamViewer app, and log in with your TeamViewer account. You need to authorise connections on the box, following which the client can see what’s happening on the Android TV. You can take screenshots and record videos from TeamViewer, but not control the actual box (which is the whole point, but eh).
