Question about Philips 50PUS7009/12

It is possible to download apps to your Philips Smart TV. You can do this via the app store on the TV. If you want to install apps such as GAIA that are not available in the app store, you could consider installing them via external sources such as APK files, but this is not officially supported and may not work. For officially supported apps, you can use the Philips TV Remote app or navigate directly from the TV interface.
