Lock screen during a call on Xiaomi Redmi Note 10 Pro: 5 working ways

Accidental taps during a phone conversation are a common problem faced by owners of the Xiaomi Redmi Note 10 Pro. The screen does not go out immediately, which can inadvertently end a call, turn on speakerphone or activate other functions. This is especially true for those who often talk in motion or hold the phone uncomfortable. In this article, we will analyze all the available ways to force the screen to lock when calling, from standard MIUI settings to third-party solutions.

Many users mistakenly believe that the screen should lock automatically when you hold the phone to your ear. In practice, the proximity sensor Redmi Note 10 Pro does not always work instantly, and in some firmware its work is broken after updates. Fortunately, the problem is solvable - and for this you do not need to install additional software. It is enough to know where to look for the right options in the menu or how to use the hardware capabilities of the smartphone.

Next, we will look at step-by-step instructions for different scenarios, from turning on the proximity sensor to using gestures and specialized applications, and pay special attention to the nuances of MIUI 12/13/14, since the interface and location of settings may vary depending on the version of the shell.

1. Checking the operation of the proximity sensor

The proximity sensor is the main mechanism that automatically shuts down the screen during a call. If it is faulty or disabled, the screen will remain active, which will lead to accidental pressing. On the Redmi Note 10 Pro, this sensor is located at the top of the display, next to the front camera.

To check his work:

1. Open the Phone app and dial ##6484## (test code to check sensors).
2. In the menu that appears, select Proximity Sensor.
3. Close the top of the screen with your hand – the value should change from 5.00 (far) to 0.00 (close).

If the sensor does not respond, the problem may be glass contamination, module damage, or software failure.

Attention! Some custom firmware may not have the test code, in which case, check the sensor through the CPU-Z app (Sensors section) or the Sensor Test from Google Play.

💡

If the proximity sensor is contaminated, gently wipe the top of the screen with an alcohol wipe. Avoid pressing hard, this can damage the sensor.

2. set up automatic locking in MIUI

In standard MIUI settings, there is an option that allows the screen to lock when the phone approaches the ear, but by default it can be turned off or not work correctly, to activate it:

Go to: Settings → Display → Automatic screen lock

Make sure that the approximation lock slider is on. If this option is not available, upgrade to the latest version of MIUI 14 or higher.

Also check the call settings:

1. Open Settings → Applications → Phone → Call settings.
2. Activate the screen lock option when approaching (if available).
3. Set the lock delay to a minimum value (usually 1 second).

On the Redmi Note 10 Pro with MIUI 12.5 and below, there may be no automatic lock option, in which case use alternative methods from the following sections.

3. Use of the gesture "Double touch to lock"

If the proximity sensor is unstable, you can lock the screen manually with a gesture. MIUI has a double-touch lock function that allows you to turn off the display with two quick taps on any area of the screen.

To activate it:

1. Go to Settings → Display → Lock screen gestures.
2. Enable the option of Double-Tap to lock.
3. Test the gesture on the home screen – the screen should go out after two consecutive touches.

This is convenient because it works independently of the proximity sensor, but it's addictive: you have to deliberately lock the screen during a conversation to avoid accidental taps.

Enable "Double touch to lock" in the display settings

Testing the gesture on the main screen

Get used to locking the screen at the beginning of each call

Check if the gesture is in conflict with other functions (e.g., double-touching to wake up)-->

4.Apps for forced screen locking

If standard methods don't work, you can install a third-party app that will lock the screen when you start a call.

• 🔒 Proximity Screen Off automatically turns off the screen when the phone is close to the ear, and works even if the standard sensor is turned off.
• 📞 Call Screen Off: locks the screen as soon as the call starts, without delay.
• 🛠️ Gravity Screen uses a proximity sensor and an accelerometer for smart locking. Suitable for the Redmi Note 10 Pro with unstable sensor.

Installation and configuration (for example, Proximity Screen Off):

1. Download the app from Google Play.
2. Run it and grant permissions to Change System Settings and Access Calls.
3. Enable the Auto Screen Off During Calls option.
4. Adjust the sensor sensitivity (high for Redmi Note 10 Pro is recommended).

⚠️ Attention! Some screen locking applications require permission to overlay over other windows. Without it, they won't be able to work properly. To give access, go to Settings. → Annexes → Special rights → Overlay over other windows.

5. Alternative methods: power button and covers

If the software solutions are not suitable, you can lock the screen mechanically:

• 📱 Magnetic Lock Case – Some cases for the Redmi Note 10 Pro support automatic locking when closed.

For the power button, you can configure a quick lock:

1. Go to Settings → Display → Lock screen.
2. Select Fast Lock and set a minimum latency (e.g. 0.5 seconds).

This will reduce the time it takes to hold the button to lock.

6. Diagnostics and resetting of sensor settings

If the proximity sensor stopped working after updating or resetting, try to return it to factory settings.

Reset the sensor settings through the engineering menu:

1. Dial the code ##4636##.
2. Select Usage statistics (Usage statistics).
3. Click on the three dots in the upper right corner and select Sensor reset.

If the engineering menu is not available, reset through Settings → About Phone → Reset → Reset application settings. This will not delete your data, but will return the standard parameters of the sensors.

After reset, restart your phone and check the sensor again. If the problem persists, you may need to flash the device or contact a service center.

💡

The most reliable way is to combine the proximity sensor and the double-touch gesture, which covers most scenarios: automatic locking when you hold it to your ear + manual locking if the sensor doesn't work.
