How to turn on the proximity sensor on Xiaomi Mi 11 Lite: a complete guide with a health check

The proximity sensor in Xiaomi Mi 11 Lite smartphones (including 5G and 4G/NE versions) is responsible for automatically turning off the screen during phone calls when you hold the device to your ear. This prevents accidental taps and saves battery power. However, many users face the problem: the sensor either does not work out of the box or turns off after MIUI updates. In this article, we will discuss all the ways to activate, diagnose and troubleshoot from basic settings to hidden functions of the engineering menu.

Despite its apparent simplicity, setting up the proximity sensor on the Mi 11 Lite is nuanced. For example, in some firmware, the option is hidden in the special features menu, and in others it requires manual calibration through service codes. We tested all methods on current versions of MIUI 13/14 (including HyperOS) and collected step-by-step instructions with visual hints that will help even beginners. If your smartphone ignores the approach of the hand or screen, do not rush to carry it to the service: in 90% of cases, the problem is solved software.

Before you start, make sure your Xiaomi Mi 11 Lite has the latest firmware installed. The proximity sensor is closely linked to the operation of the Near Field Communications (NFC) module and system services, so outdated software can block its functionality. Also check if there is physical damage at the top of the screen - that's where the sensor is located. If you recently dropped your phone or changed the display, the problem may be in the hardware.

Where is the proximity sensor on Xiaomi Mi 11 Lite

The Mi 11 Lite's proximity sensor is located at the top of the screen, to the right of the front camera, and it's a miniature infrared sensor that emits and picks up the reflected signal, and you can't see it on the outside, it's hidden under the display glass, but you can roughly define the range:

📱 Location: 1–1.5 cm to the right of the camera (when looking at the screen with your face).
🔍 Surrounding area: radius ~3-5 cm from the sensor. The sensor is triggered when an object (such as an ear or palm) blocks the signal.
⚠️ Vulnerability: When changing glass or display, the sensor may be damaged or displaced, leading to false positives.

Unlike the older Xiaomi models, where the proximity sensor was paid for a fee, the Mi 11 Lite integrated it into a flexible display plume, which means that if you don't have a screen repair, the sensor can fail. If you've recently changed the display and the sensor stopped working, the most likely problem is that the plume is not installed correctly or damaged.

To check whether the sensor is responsive to the approach, you can use the test mode:

Open the Phone app and dial ##6484##.
Select the Proximity Sensor Test.
Close the sensor with your palm - the screen should go out, when removing your hand - light up again.

💡

If the test mode doesn't start, try the code ##4636## → Phone Information → Equipment Check.

How to turn on the proximity sensor through the MIUI settings

In most cases, the proximity sensor activates automatically after the first call, but sometimes you need to manually adjust. MIUI 12/13/14 HyperOS:

Go to Settings → System → Additional settings.
Select Special Features (or Universal Access in New Versions).
Scroll down and find the System Settings section.
Activate the proximity sensor switch (or Automatic Screen Shutdown).
Reboot your phone to make the changes take effect.

If your MIUI version does not have an explicit "Approximation Sensor" item, try an alternative path:

Open Settings → Applications → Application Management.
Click on the three dots in the upper right corner and select Show System.
Find the Phone app (com.android.dialer) and open its settings.
Turn on the approach sensor option when calling.

Make sure your phone doesn’t have a security film in the sensor area | Check that your smartphone isn’t in power saving mode | Turn off VPN or proxy – they can block system services | Update your firmware to the latest version

-->

On some firmware (especially custom) the option may be called differently:

🔄 Auto screen-off during calls (Automatically switching off screen during calls)
📞 Proximity sensor calibration (calibration of the proximity sensor)
🔧 Sensor settings (Sensor settings)

What to do if the settings do not include the item "approximation sensor"?

If the option is missing, this can mean: 1. Firmware without sensor support (for example, ported from another device). 2. System service is disabled - try resetting to factory settings (Settings → About phone → Resetting). 3. Hardware malfunction - diagnostics is required at the service center.

If the sensor is not working properly (for example, the screen is dimming with a delay or does not respond to approach), manual calibration may be required.

Open the Phone app and enter the code: ##36446337##
In the menu, select Proximity Sensor.
Press Calibrate and follow the instructions on the screen.
After calibration, check the values of Near (close) and Far (far) - they should differ sharply when approaching / removing the hand.

Normal sensor values:

📊 Far (far): 5–10 cm (value) ~0–50).
🤲 Near (close): 0–2 cm (value) ~200–255).

If the indicators do not change or are close to each other, the sensor is defective.

An alternative way to calibrate is through the MTK Engineering Mode app (for Qualcomm Snapdragon 732G processor-powered devices, as in the Mi 11 Lite 4G):

Download the app from Google Play.
Run it and go to Hardware Testing → Sensors → Proximity Sensor.
Press Do Calibration and confirm the action.

💡

The calibration of the sensor is reset after the phone is reset to factory settings or firmware updates, and then the procedure must be repeated again.

Checking the operability of the proximity sensor

If the sensor is not responsive to the settings, first check its hardware performance. Here are 3 reliable methods:

Test through code: Dial ##6484## → select Proximity Sensor Test. Close and open the sensor with your hand - the screen should go out and light up synchronously. If there is no reaction, the sensor is faulty.
App check: Install Sensors Multitool from Google Play. In the Proximity section, see if the values change as your hand approaches.
Diagnostics via ADB: Connect your phone to your PC, enable USB Debugging and execute the command: adb shell dumpsys sensorservice In the output, find the Proximity Sensor string – if the status is unavailable, the sensor is disabled at the system level.

Typical signs of sensor malfunction:

❌ The screen does not go out during the ringing (remains active in the ear).
❌ The screen goes off arbitrarily, even when the phone is on the table.
❌ In the engineering menu, the sensor values do not change (Near). = Far).

💡

If the sensor is delayed (e.g., the screen goes out 2-3 seconds after you touch your ear), try turning off the Rise to wake function in the screen settings.

Typical problems and their solutions

Even after setting up correctly, the proximity sensor on the Xiaomi Mi 11 Lite can malfunction.

Problem.	Possible cause	Decision
The screen does not go out during the call.	Sensor is disabled in settings or faulty	Turn on the sensor in Special Options or check it through the Engineering Menu
The screen goes out arbitrarily	False positives due to protective film or sensor damage	Take the film off, calibrate the sensor, or replace the display
The sensor only works after restarting.	Conflict with MIUI optimization or third-party applications	Turn off auto-optimization in Settings → Battery → Optimization
In the engineering menu, the sensor shows "N/A"	Sensor turned off at nucleus level or plume damaged	Check the phone or contact the service.

If the problem persists after all the manipulations, check:

🔋 Power saving mode: turn it off in Settings → Battery.
🛠️ Third-party applications: Some launchers (such as Nova Launcher) may block system services.
📱 Updates: Is the latest firmware version installed for your model (Mi 11 Lite) 4G or 5G).

What if the sensor stopped working after the update?

After major MIUI updates (e.g. 12 to 13), system services can be reset. Try: 1. Reset Settings → About Phone → Reset All Settings → Reset (without deleting data). 2. Install firmware manually via Fastboot (instructions on Xiaomi Firmware Updater). 3. Reverse the previous version of MIUI if the problem appears after the update.

Hardware malfunctions: when you need a replacement

If the software methods didn’t help, the problem is probably hardware. The proximity sensor in the Xiaomi Mi 11 Lite can fail for the following reasons:

💥 Phone drop: Even a minor bump to the top of the screen can damage the sensor plume.
🔧 Poor repair: when replacing the display wizard often damage the flexible contacts of the sensor.
💧 Moisture: oxidation of contacts on the board leads to unstable work.

Critical sign of hardware failure: the sensor is not detected in the Engineering Sensor (Proximity Sensor: N/A) and does not respond to calibration.

Display plume (together with sensor).
The sensor itself (if it is separate).
Front camera module (in some versions, the sensor is built into it).

Cost of repairs in service centers:

💰 Replacement of the plume: ~1 500–2 500 ₽.
💰 Replacement of sensor: ~1 000–1 800 ₽ (If a separate replacement is possible).
💰 Diagnostics: ~500 ₽.

💡

Before repair, check the warranty! If the phone is warranty, do not disassemble it yourself - this will void the manufacturer's obligations.

Frequently asked questions

🔹 Why the proximity sensor only works with charging?

This is a typical problem with unstable power in the sensor module. Try: Clear the charging port contacts (possibly oxidation); Turn off fast charging in Settings → Battery; Reset the battery settings (Settings → Applications → Battery Management → Reset); If it doesn't help, a malfunction in the power controller (diagnosis required).

🔹 Can I turn off the proximity sensor forever?

Yes, but it's not recommended -- the screen will remain active during calls, which will cause random taps. ADB-Adb shell settings put global proximity_sensor_disabled 1 Or install the Tasker app and create a task to turn off the sensor.

🔹 The sensor works when the phone is in your pocket?

This is because of the sensitivity of the sensor. Solutions: Calibrate the sensor through the engineering menu (reduce the trigger threshold). Turn off the Smart Cover function in the screen settings (it can conflict). Use a magnetic lock case - it locks the screen when it closes.

🔹 After the screen was replaced, the sensor stopped working?

Options: Return to the service and demand warranty repair. Check the connection of the plume yourself (requires disassembly of the phone). If the sensor is built into a new screen, you may have installed an unoriginal spare part without a sensor. Attention: non-original displays often go without a proximity sensor!

🔹 How to check the proximity sensor without a call?

There are several ways: Use the Sensors Multitool app, it has a sensor test. Type ##0*## → select Proximity (not all firmware). Close the sensor with your hand while watching the video — if the screen goes out, the sensor works.
