How to Install APK in Fire TV Stick?

Fire TV OS has a Developer Options menu in the Settings app, which contains the settings for Android Debug Bridge (ADB) and sideloading applications. Both of those features are important for installing apps not available on the Amazon Appstore or even installing third-party app stores. The Developer Options menu used to always be visible in the Settings, but Amazon is rolling out an update to some models that hides it by default.

1. Unhide Developer Options on Fire TV Stick

You just have to navigate to Settings > My Fire TV > About, and then keep clicking the device name until you see a “You are now a developer” popup. After that, the Developer Options menu shows up like normal.
