If you own a Xiaomi Smart TV, you've probably noticed that the standard settings menu is quite limited. However, as with almost every device from the brand, there's a hidden backdoor that allows you to delve into the system's inner workings and access settings that Xiaomi generally prefers to keep hidden from the average user.
The truth is that these TVs run on Android TV , even though they're disguised as PatchWall, which means they inherit all the quirks of Google's software . Accessing this secret menu isn't rocket science, but you have to be careful because if you start changing things without really knowing what they do, you could leave the TV behaving strangely or even void the warranty.
Steps to activate developer options
To enter this advanced mode, you don't need any unusual codes or special controls, just follow a specific path in the interface. First, go to the gear icon or Settings section , which is usually located in the upper right corner of the home screen. Once there, scroll down to find the Device Preferences section and then go to the About tab.
This is where the magic happens. You need to find a line that says " Build number ." The trick is to repeatedly press the center button on your controller (between five and seven times) on that word. You'll see a message appear telling you how many steps you have left to become a developer until, finally, the system confirms that the developer options are now enabled.
However, the menu doesn't magically appear on the current screen. You have to go back one level in the settings and look in the main list. You'll see a new section called Developer Options or Developer Features, where all the technical settings are hidden.
What can you actually do in this hidden menu?
Once inside, you'll find an endless list of options that might seem like gibberish if you're not a programmer, but several are pure gold for the user . For example, you can change the speed of system animations; if you set them to 0, the interface feels much faster and smoother because you eliminate the visual transitions.
For those with vision problems or who want to examine the content more closely, there's a magnifying glass function that enlarges the image up to four times. You can also experiment with the color space or force the MSAA 4x filter to try and improve the graphics quality , although the latter may vary depending on your specific hardware model.
One of the most powerful advantages is the ability to enable USB debugging and OEM unlocking. This is essential if you like to install third-party apps via APK that aren't available on the official Google Play Store, allowing you to customize your TV to your liking.
Other diagnostic tools and codes
It's important to distinguish between the TV's developer menu and the hardware testing menus (like the CIT menu) that are more common on Xiaomi phones. While on TVs we focus on the Android software, on phones secret codes like *#*#6484#*# are used to test the screen, speaker, or proximity sensor.
Compared to other brands, Xiaomi is simpler since it doesn't require complex button combinations like Samsung or Philips. However, if you ever need to perform in-depth HDMI diagnostics or calibrate the sound at a technical level, this developer mode is your best ally for monitoring RAM usage and hardware acceleration in real time.
If at any point you feel you've changed too many settings and want to revert to normal, don't worry. Simply go back into the developer menu and uncheck the enable box . With a single click, the entire section will disappear from the main settings, and your TV will return to its default state.
Mastering these hidden functions allows you to transform a standard television into a much more efficient machine, allowing you to optimize system response speed and install alternative software, as long as you act prudently so as not to compromise the stability of the device.
