How to Remove Screenlight on Xiaomi: A Step-by-Step Guide for All Models

The screen lighting on Xiaomi devices is one of those features that can both make it easier to interact with the gadget and cause discomfort. Too bright in the dark screen cuts your eyes, and automatic brightness adjustment sometimes works incorrectly, forcing users to manually adjust settings. In this article, we will examine all possible ways to turn off or adjust the backlight, from basic options in the menu to hidden commands for power users.

It's important to understand that "backlighting" often means different things: it can be automatic brightness control, night light, flash notifications or even keylights on some models. We'll look at each case separately so you can fine-tune the device to your needs. We'll focus on the problems associated with the light sensor, which often causes malfunctioning of automatic backlighting.

The instructions in the article are relevant for all modern Xiaomi, Redmi and other devices. POCO base MIUI 12-14 and HyperOS, and for Mi TVs TV. If your model is released before 2018, some menu items may be different – in this case, use alternative methods from the last sections.

1. Disconnecting automatic brightness control

The most common problem is when the screen spontaneously changes brightness depending on the lighting, a feature called adaptive backlighting, which is activated by default on most devices, to turn it off:

1. Open the Settings → Display.
2. Slip on Brightness (or Automatic Brightness in some firmware).
3. Transfer the slider Automatic adjustment to the position off..
4. Manually set a comfortable brightness level with a slider.

On some models (for example, Xiaomi 13 Pro or XP) POCO F5) This item may be hidden behind additional settings. If you don't see the option right away, try it:

• 🔍 Go to Settings. → Additionally. → Special facilities → Display setting.
• 📱 On Mi TVs. TV The way will be different: settings → Picture → Brightness → Autobrightness.
• 🔄 If the brightness still changes after the automatic adjustment is turned off, then the problem is in the light sensor (see section 4).

Important: On devices with AMOLED-screens (e.g. Xiaomi) 12T or Redmi K50 Pro) turning off the automatic brightness may result in a faster battery discharge, as the system optimizes energy consumption depending on the lighting conditions.

2. Night mode setting (Night Light)

Night Light reduces the amount of blue light coming from the screen, which reduces the load on the eyes in the evening, but some users confuse it with backlighting per se.

1. Go to Settings → Display → Night mode.
2. Turn off the slider Enable the night mode.
3. If you want to leave the function, but adjust it to your taste: 🌓 Set the color temperature to a minimum (the warmest shade). ⏰ Set up a schedule (for example, from 22:00 to 7:00). 🔄 Enable the option to automatically turn on at sunset, if available.

On Mi TVs. TV A similar function is called Read Mode and is located in Settings. → Picture → Image mode → Read mode, shutting it down will bring back standard color reproduction.

On HyperOS devices (e.g. Xiaomi 14 or Redmi Note 13 Pro)+) The night mode can be integrated into the Digital Well-Being system. To turn it off, go to Settings. → Digital well-being → Night mode.

💡

If night mode is turned on spontaneously, check the settings of the Google application (section "Google Play Services" → Digital well-being. Sometimes it redefines system parameters.

3. Disabling key highlighting and notifications

On some Xiaomi models (e.g. Redmi Note 10 Pro) POCO X3 Pro) has a touch key backlight or LED notification indicator to turn them off:

Touch buttons (navigation panel)

• 📱 Go to Settings. → Display. → Full screen mode.
• 🔘 Select the navigation buttons (if they are active).
• 💡 Turn off the button lighting or button animation option.

LED notification indicator

• 🔔 Go to Settings. → Notifications → Notification indicator.
• 🔕 Turn off the slider Show the indicator.
• 🎨 If you want to leave but change the color, tap the color of the indicator and choose the right one.

On Mi TVs. TV The backlight can come in the form of a glowing frame or a logo to remove it:

1. Go to Settings. → System system → About the system → Standby regime.
2. Turn off the logo lighting or LED-indicator.

4. Problems with the illumination sensor and their solution

If the automatic brightness control is not working properly (for example, the screen dims in normal light or, conversely, becomes too bright in the dark), the problem is most likely in the light sensor.

Testing of sensor operation

• 📱 Install the Sensor Test application (for example, CPU-Z Sensor Box from Google Play).
• 🔦 Start the Light Sensor test).
• 💡 Point the flashlight at the sensor (usually located next to the front camera) – the values should change dramatically.

If the sensor is not responding, try the following steps:

Solutions

1. Sensor cleaning: Wipe the area around the front camera with a soft napkin. Dust or dirt can block the signal.
2. Calibration: Some firmware has a hidden calibration option. -n com.android.settings/.DevelopmentSettings Then find the calibration point of the light sensor.
3. Resetting settings: Go to Settings → System system → Resetting settings → Reset all settings (does not delete data, only returns settings to factory settings).

Note: If the sensor is physically damaged (for example, after a device falls), it can only be replaced at a service center.

💡

If the light sensor is faulty, the only reliable way to get rid of backlight problems is to completely turn off automatic brightness control and use manual settings.

5. Hidden backlight settings through developer modes

For power users, there are additional options that are not visible in the standard menu.

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified "You became a developer").
3. Return to the main settings menu and open Additional → for developers.

Now you can set up:

• 🔄 Brightness animation - disables the smooth change in backlight.
• 📊 Minimum brightness – sets a lower threshold (useful if the screen is too dim).
• 🌈 Simulation of color space - changes the color gamut (can affect the perception of backlighting).
• 🔍 Brightness debugging - shows the current values of the light sensor.

On Mi TVs. TV Similar settings are hidden behind the button combination on the remote:

Press sequentially: Menu → 1 → 3 → 7 → 9 → Menu

After that, a service menu will open where you can calibrate backlight (Backlight) and contrast (Contrast).

⚠️ Warning: Changing the settings in developer mode can cause the device to work in an unstable way. Do not change the settings if you are not sure about their purpose. For example, improper calibration of the minimum brightness can make the screen unreadable in daylight.

6.Alternative methods: ADB and third-party applications

If the standard methods don't work, you can use developer tools or third-party utilities, which are suitable for advanced users.

Turning off the lights through ADB

Using Android Debug Bridge (ADB) You can force the automatic brightness to turn off or change the brightness parameters:

1. Install. ADB-computer-assist.
2. Connect the phone to the PC and allow debugging over USB.
3. Execute the commands: adb shell settings put system screen_brightness_mode 0 # Disables automatic brightness adb shell settings put system screen_brightness 100 # Set the brightness on 100%

Subtle tuning applications

• 🔧 Lux Auto Brightness – allows you to create your own brightness profiles.
• 🌓 Night Screen is an alternative to the standard night mode.
• 📱 Display Tuner - Advanced color reproduction and backlight settings.

Important: When used ADB or third party applications, remember that:

• Some teams demand root rights.
• Changes can be reset after the firmware update.
• On Mi TVs. TV ADB-Teams work differently – they need special ones. ADB-server TV.

7. Features of setting the backlight on Mi TVs TV

Xiaomi TVs have their own backlight control logic, which depends on the type of matrix (LED, QLED or OLED). Main differences:

• 📺 Nana LED-TVs (e.g. Mi) TV A2 43) the illumination is adjusted through the Settings → Picture → Backlight: The optimal value is 80-90% for day viewing.
• 🌈 Nana QLED-models (e.g. Mi models) TV Q2 55”) added the local dimming parameter, which affects contrast.
• 🖤 Nana OLED-TVs (e.g. Mi) TV OLED 65") there is no backlight as such - each pixel glows independently. OLED.

For all types of TVs, the following tips are relevant:

1. Turn off Auto Brightness in the picture settings if it interferes.
2. In the Image Modes section, select User and manually adjust Brightness, Contrast and Color Temperature.
3. If the screen is too dark in movie mode, increase the Gamma setting.
