Do you talk on the phone and the screen suddenly goes out in 3-5 seconds? This problem is familiar to many owners of Xiaomi, Redmi, Poco and Black Shark smartphones - especially after the MIUI 12-14 updates. The feature of automatically turning off the screen during a call should save battery power, but in practice it often interferes: you can not turn on speakerphone, switch to headphones or watch contacts. Fortunately, it can be turned off - and we will tell you how to do this 7 different ways, including hidden settings and workarounds for older models.
In this article you will find:

Why Xiaomiโs screen goes out during a call: 3 main reasons
The automatic screen shutdown feature appeared in MIUI 9, but was introduced with MIUI 12.
- Battery savings โ the screen consumes up to 30% of the charge when used actively.
- Protection against accidental pressing (for example, when the phone is pressed against the ear).
- Compliance with energy efficiency standards for certification in the EU and China.
However, the implementation was raw: on many models, the screen goes out even if you do not press the phone to your face (for example, when using a headset or hands-free), Moreover, on some firmware, the function works after 3 seconds, which leaves no time for manipulation of the interface.
| Model/firmware | Time to screen-extinguishing | Can I turn off the settings? |
|---|---|---|
| Xiaomi 12/13 (MIUI 14 Global) | 5 seconds | Yes (hidden in "Special Opportunities") |
| Redmi Note 11 (MIUI 13 EEA) | 3 seconds | No (ADB required) |
| Poco F4 (MIUI 14 India) | 7 seconds | Yeah (in call settings) |
| Black Shark 5 (JoyUI) | Deactivated by default | No data. |
Interestingly, Chinese firmware (CN ROM) often doesnโt have this problem, probably because of different energy standards, but global and European versions (EEA/Global ROM) are more likely to suffer.
โ ๏ธ Warning: If the screen goes off instantly (less than 1 second) and doesn't respond to touches even after unlocking, it could be a hardware malfunction of the proximity sensor##).
Method 1: Disconnect via standard MIUI settings
On some models, the option is hidden in non-obvious sections. Check these paths (depending on the version of MIUI):
Check the Settings. โ Special facilities โ Approximation sensor|Open the Settings. โ System system โ Additionally. โ Turn off the screen when you call.|Get on the phone. โ Settings (โ๏ธ) โ Turn off the screen during the call|Look at the settings โ Battery โ Optimization โ The screen when you ring.-->
If none of the items worked, try searching by settings:
- Open the Settings.
- Slip on the icon of the magnifier (search) in the upper right corner.
- Enter the request: the screen when calling or the proximity sensor.
On the Poco F3/F4 and Xiaomi 11T, the option may be called โScreen off during callsโ โ it must be turned off (slider left).
๐ก
If you don't find anything in the search, try changing the system language to English (Settings โ Additional settings โ Language & input).
Method 2: Use of the Engineering Menu (for advanced)
If standard methods don't work, you can try calibrating the proximity sensor through the engineering menu, which will help if the sensor is not working properly.
1. Open the phone app.
2. Enter the code: ##6484## (to check the proximity sensor).
3. If the code didn't work, try ##4636## โ "Equipment Testing."
4. Find the Proximity Sensor and tap on it.
5. Close the top of the phone (where the sensors are located) with your hand โ the value should change from 5.0 cm to 0.0 cm.
6. If the values do not change, the sensor is defective.To reset the sensor calibration:
1. Enter the code ##64663## (on some models).
2. Select Proximity Sensor Calibration.
3. Follow the instructions on the screen (usually close/open the sensor with your hand 3-5 times).โ ๏ธ Warning: Incorrect calibration can cause the screen to be permanently activated during calls (which drains the battery) or, conversely, to fail the sensor completely.
Method 3: ADB-commands
On MIUI 13/14 Global/EEA, the screen shutdown option is often hidden, and can be activated via ADB (Android Debug Bridge), a technique that requires a computer, but works on 90% of Xiaomi models.
What you need:
- ๐ฅ๏ธ Computer with Windows/macOS/Linux
- ๐ฑ USB-cable (original)
- ๐ง Included debugging by USB (Settings โ The phone. โ Version. MIUI โ Tap 7 times according to version โ Come back to the extra. โ For developers โ Debugging by USB)
Step-by-step:
- Download ADB Tools and unpack the archive.
- Connect your phone to your PC and select File Transfer mode.
- Open the command line (Windows: Win + R โ cmd) and go to the folder with ADB: cd C:\platform-tools
- Enter the command to check the connection: adb devices (the name of your device should appear)
- Execute the command to disable screen quenching: adb shell settings put global proximity_delay 2500 (significance 2500 โ delay in milliseconds; set 0 shutdown)
- Reboot the phone.
If the team doesnโt work, try an alternative:
adb shell settings put system screen_off_timeout_call 0๐ก
After completion ADB-And if you're going to go out, check the proximity sensor on the engineering menu, and if you're going to stop going out, even when you're coming in, put the delay back on the back. 1500-3000 MS for a balance between convenience and battery savings.
Method 4: Third-party applications (if nothing helps)
If previous methods have failed, you can use apps from Google Play that force you to block screen blackouts.
| Annex | How it works | Cons |
|---|---|---|
| Proximity Sensor Fix | Emulates the constant โremovalโ of the phone from the ear | It drains the battery, can interfere with other sensors |
| Smart Stay | Uses a front-facing camera to track your eyes | It requires camera permission and does not work on all models. |
| Screen On During Call | Forced to turn on the screen when calling | Can conflict with MIUI, requires access authorization |
How to set up Screen On During Call:
- Install the application and open it.
- Turn on the "Keep screen on during calls" switch.
- In the window that appears, click "Availability Settings" and activate the permission for the application.
- Reboot the phone.
โ ๏ธ Note: Apps that use the Accessibility Service can read your passwords and personal data. Install only trusted high-rated utilities (4.5).+).
Method 5: Update or roll back firmware
If the problem occurred after the MIUI update, it may be a bug of a particular version, in which case:
- ๐ Reverse to previous firmware (via Fastboot or Recovery).
- ๐ฒ Install custom firmware (for example, LineageOS or Pixel Experience).
- ๐ง Cleaning the cache system (in Recovery Mode).
How to check if it is not a bug:
- Go to Settings โ About the phone โ System update.
- See the version of MIUI (e.g. V14.0.3.0.TKBCNXM).
- Search the Internet for complaints about your model + firmware version (for example: Redmi Note 12 MIUI 14.0.2 screen goes out).
If the bug is confirmed, wait for the next update or roll back.
- Download the necessary firmware version from the official Xiaomi website.
- Rename the file to update.zip and place it in the root of the phoneโs memory.
- Go to Settings. โ The phone. โ Updating the system โ Three points (โฎ) โ Select a firmware file.
What if the screen stopped working after the rollback?
Method 6: Hardware check (if the screen goes out on all firmware)
If the screen goes out even after resetting settings and on different firmware, the problem may be:
- ๐ฑ Faulty proximity sensor (often after falls or moisture hits).
- ๐ A bloated battery that presses on the sensor plume.
- ๐ Oxidized contacts on the motherboard.
How to check the proximity sensor without disassembly:
- Install the Proximity Sensor Test application.
- Open it and look at the sensor response graph.
- Close and open the top of the phone with your hand โ the schedule should change dramatically.
- If the graph is flat (no reaction) the sensor is faulty.
Cost of repair:
| Problem. | Cost (โฝ) | Difficulty |
|---|---|---|
| Replacement of the proximity sensor | 800โ1 500 | Medium (swinging iron needed) |
| Cleaning contacts | 500โ1 000 | Low. |
| Replacement of the plume | 1 200โ2 000 | Tall. |
| Battery replacement | 1 500โ3 000 | Medium |
โ ๏ธ Warning: If you notice that the screen spontaneously turns on in your pocket or responds to touch without touching, this is a sign of a sensor closure. ADB (adb shell settings put global proximity_sensor_enabled 0), But it will also disable other functions (for example, automatic speakerphone switching).
