How to change the color of the notification indicator on Xiaomi Poco X3: all ways

The LED light on the Xiaomi Poco X3 is not just a decoration, but a useful tool for alerting: it flashes white or blue by default, but many users want to personalize it to their preferences. Unfortunately, the manufacturer did not provide direct settings for changing the color in the standard menu, which causes confusion among owners.

There are actually several ways to change the color of an indicator, from simple tricks with theme settings to using hidden MIUI features and third-party apps, and in this article, we’ll break down all working methods, including those that work without root rights, and explain why some colors may not display correctly on your device.

Why you can’t change the color of the indicator on Poco X3 through standard settings

Unlike Xiaomi’s flagship models, where the color of the indicator is adjusted through Settings → Notifications → LED indicator, Poco X3 does not have this menu item.

• 🔹 Limitations MIUI Poco: Firmware simplified to improve productivity.
• 🔹 Single-channel RGB-Indicator: Physically, the device supports a limited palette of colors.
• 🔹 Xiaomi: budget models cut “unnecessary” functions to reduce the price.

But that doesn't mean you can't change the color, because the manufacturer left loopholes through hidden menus, ADB-The key is to understand the risks: wrong actions can lead to a malfunction of the indicator or even system notifications.

Method 1: Change color through theme settings (no root)

The safest method is to use built-in MIUI themes that indirectly affect the color of the indicator, which does not give you complete choice, but allows you to change the shade from white to blue, green or red depending on the chosen theme.

Instructions:

1. Open Settings → Theme.
2. Select My Themes and click Download New Ones.
3. In the search, type in the queries: "LED", "Neon" or "Dark".
4. Set a theme with the color of the indicator in the description (for example, “Dark neon”).
5. Apply the theme and restart the device.

The effect will not appear immediately — sometimes it takes up to 10 minutes for the system to apply the changes to the indicator. If the color has not changed, try a different theme or clear the Settings app cache through Settings → Applications → Application Management.
