The Amazon Fire TV and Fire TV Stick have a hidden Developer Tools Menu (previously called the System Status Monitor menu) that contains diagnostic options, most notable of which is a System X-Ray bar which displays CPU, memory (RAM), and network usage. Here is how to access the secret menu and an explanation of each option.
Launching the Developer Tools Menu
Using a Remote Control: Press and hold the CENTER and DOWN buttons together for 5 seconds, then release those buttons and press the MENU button.
Using a Game Controller: Press and hold “A” and “Y” buttons together for 5 seconds, then release those buttons and press the MENU button.
Using an App Launcher: You can use an app, like ES File Explorer, that is capable of listing and opening system apps. Go to the app area, be sure system apps are visible, and select the “System Status Monitor” app to open the developer tools menu.
Using ADB: Connect to the device via ADB and run the command:
The hidden menu was added with Fire OS 5, so you won’t find it on devices running Fire OS 3. Depending on which version of Fire OS 5 your Fire TV or Fire TV Stick is running, the menu may have a different name and/or different options.
The “System X-Ray” option is a bar that appears at the top of the screen and is displayed over everything, regardless of which app is being used. It contains display, CPU, memory, and network information. For a complete overview of the System X-Ray bar, see this post.
The “Developer Options” item was added with the 184.108.40.206 software update. Enabling the “Developer Options” item seems to just open a submenu with a single “Clear Recommendations” option. I wouldn’t be surprised if a future software update moves the “ADB Debugging” and “Apps from Unknown Sources” options, found currently in the Fire TV’s regular settings menu, into this developer tools menu. I can’t tell what the “Clear Recommendations” option does exactly. If you can tell, please comment below.
Launch Network Advisor
The “Launch Network Advisor” option simply opens the same network diagnostic tool found in the Fire TV’s network settings menu.
