How to Remove Screen Dimming on Xiaomi During a Call: The Complete 2026 Guide

Xiaomi's screen goes out in the middle of a conversation, causing you to poke around the display to return the image? This problem is familiar to many owners of smartphones on MIUI - especially after system updates. Unlike other manufacturers, where the screen remains active during a call, Xiaomi by default includes an energy-saving mode that puts out the display after 3-10 seconds of inactivity. But there is a solution!

In this article, you will find 5 proven ways to turn off the dimming of the screen when calling – from standard settings to hidden MIUI functions and even ADB commands. We will analyze methods for different versions of the firmware (from MIUI 12 to MIUI 14), and also explain why some methods may not work on new models of Redmi or POCO.

The problem with screen dimming during a call on Xiaomi is related to the energy saving policy that the company has implemented to increase battery life. However, for many users this creates inconvenience — especially if you often call on speakerphone or use headphones. Fortunately, MIUI provides several ways to disable this feature, although not all of them are obvious.

Why does Xiaomi’s screen go out during a call?

The reason is because of the proximity sensor settings and power management policy, which is that when you hold your phone to your ear, the sensor locks the screen to avoid random taps, but on Xiaomi, this mechanism works more aggressively: even if you hold your smartphone in front of you (for example, during a video call), the display can go out in a few seconds.

Here are the key factors influencing screen behavior:

• 🔋 Power saving mode: Background activity restriction enabled leads to forced shutdown of the display.
• 📱 Approximation Sensor: On some models (for example, Redmi Note 10 Pro) the sensor is triggered falsely.
• 🔄 Updates MIUI: After updates to MIUI 13/14 Many users complain about the return of the problem.
• 🎧 Headset usage: With connected headphones, the logic of the screen changes.

Important: On models with AMOLED-screens (e.g. Xiaomi) 12T or POCO F5) The fading may be due to the Always-On Display function, which conflicts with the proximity sensor.

Method 1: Disabling the proximity sensor in the call settings

The easiest method is to deactivate the sensor that locks the screen, which works on most devices with MIUI 12-14, but may not be available on some budget models (e.g. Redmi 9A).

Instructions:

1. Open the phone application (pipe icon).
2. Press three points (⋮) in the upper right corner and select Settings.
3. Go to the Approach Sensor (or during a call on new versions).
4. Turn off the option to turn off the screen when approaching.

If there's no sensor, then your model uses an alternative screen control mechanism, in which case, try the following method.

Method 2: Adjust screen waiting time in call mode

Some versions of MIUI (e.g. MIUI 13 Global) have a hidden option that allows you to set a screen timeout during a conversation, which does not turn off the sensor completely, but increases the time to fade.

How to set up:

1. Go to Settings → Display.
2. Select Sleep Mode (or Screen Timeout).
3. Click on the Additional settings (if any).
4. Find the item during the call and set the value Never or 30 minutes.

💡

If the “During Call” option is missing, try to turn on Developer Mode first (7 times click on “Version” MIUI" In "About the phone" and then check the settings again.

Method 3: Use ADB commands (for power users)

If standard settings don’t work, you can use Android Debug Bridge (ADB), a method that requires connecting your smartphone to your computer, but delivers 100% results on most devices.

Step-by-step:

1. Download and install ADB Tools on PC.
2. Turn on USB Debugging on your phone (Settings → About Phone → MIUI Version → 7 times Press → Return to Additional → For Developers).
3. Connect Xiaomi to your computer and confirm the debugging permission.
4. Open the command prompt (Windows) or terminal (Mac/Linux) in the folder with ADB.
5. Enter the command: adb shell settings put global proximity_delay 0 This will turn off the delay of the proximity sensor.
6. To cancel changes, use: adb shell settings delete global proximity_delay

⚠️ Attention: Misuse of the right ADB This can cause sensor failures. Before making changes, back up your data through Settings. → Additionally. → Backup.

Method 4: Third-party applications for screen control

If you don't want to dig into settings or use ADB, you can install specialized utilities.

• 📱 Proximity Sensor Fix - adjusts the proximity sensor, suitable for the Redmi Note 11 and similar models.
• ⏱️ Keep Screen On – Forced to keep the screen on during calls.
• 🔧 MIUI Hidden Settings – Reveals Hidden Firmware Options, Including Sensor Management.

How to install and configure:

1. Download one of the apps from Google Play (links above).
2. Provide all the necessary permissions (access to sensors, overlay over other windows).
3. In the application settings, find the Calls or Approximation Sensor section.
4. Activate the option to turn off the screen dimming.

⚠️ Note: Some antiviruses (e.g. Avast) may block these utilities from working as suspicious. Add the app to exceptions or temporarily disable protection during settings.

Method 5: Reset sensor settings (if nothing helps)

In rare cases, the problem is that the proximity sensor calibration fails, which is common in devices after drops or updates, to reset the settings:

Instructions:

1. Go to Settings → About the phone → All specs.
2. Find the Sensors and press it 5 times in a row.
3. In the menu that opens, select Sensor Reset.
4. Confirm the action and restart the phone.

💡

Resetting the sensors will return the factory sensitivity settings, and after the procedure, gestures and automatic brightness may need to be retuned.

If the reset didn’t help, the sensor itself may be faulty. In this case, contact the Xiaomi service center – on models with a valid warranty (Xiaomi 13 Lite, Redmi Note 12 and later), repair is free.

Additional advice for specific models

Some Xiaomi smartphones have unique features that affect the screen during a call.

For the POCO F3/F4 GT:

• Use Game Turbo to force the screen to hold (add the Phone app to the list of games).
• Turn off MIUI Optimization in the battery settings for the Phone application.

For Xiaomi 12S Ultra and 13 Pro:

• The problem may be with Always-On Display. Turn it off in Settings → Display → Always-On.

For Redmi 10/10A:

• These models often suffer from the sensor sticking, blowing into the top speaker area (where the sensor is located) or wipe it with a napkin.
• Set a minimum screen wait time (Settings → Display → Sleep Mode → 30 seconds).
