Why does Xiaomiβs screen turn off when you call and not respond?
The situation when the screen of Xiaomi goes out when incoming or outgoing call and does not turn back on, is familiar to many owners of smartphones of this brand. The problem can manifest itself in different ways: sometimes the display just dims, but the call continues (you hear the interlocutor), and sometimes the phone completely βhangsβ β does not respond to buttons, does not leave the call mode and requires a forced reboot.
In practice, the culprits can be both software failures (application conflict, firmware errors, incorrect power saving settings) and hardware malfunctions (damage to the display plume, battery connector or proximity sensor, POCO X3 Pro and Mi 11 are often found with a proximity sensor bug, which causes the screen to turn off and not turn back on even after the call is completed. 9A) The problem may be associated with a poor-quality plume of the display, which over time shatters.
It's important to distinguish between a temporary glitch (like after a MIUI update) and a serious breakdown: If the screen only goes out when you make calls, but the rest of the time it works normally, it's probably the software's fault. If the phone dies in other situations (when charging, when the camera starts), it's worth checking the hardware, then we'll go through both scenarios and give you clear instructions on what to do in each case.

1. Approximation sensor check - first aid
The most common reason why Xiaomi's screen goes out during a call and doesn't turn on is because the proximity sensor is incorrect, and it's responsible for turning off the display when you hold your phone to your ear so you don't accidentally press the buttons with your cheek, and if the sensor is contaminated, damaged, or blocked by the film/case, it can wilt and leave the screen off even after the conversation is over.
How to check the proximity sensor on Xiaomi:
- π Visual inspection: Find a sensor (usually located next to the front camera, looks like a small hole or a transparent window) and make sure it is not covered by film, cover or dirt.
- π± Testing through the Engineering Menu: Enter the code ##6484## β Choose Proximity Sensor β If the values don't change (left 1.00 or 5.00), the sensor is defective.
- π Calibration: Go to Settings β System system β Additionally. β Calibration of sensors (not available on all models).
If the sensor is working, but the screen still does not turn on after the call, try turning off the display automatically:
- Open the settings β Applications β Phone.
- Select Incoming Calls.
- Turn off the option Automatically Shut Down Screen (or Approach Sensor).
π‘
If the engineering menu doesnβt open with the code, try installing the Sensor Test app from Google Play, which will show the status of all sensors, including the proximity sensor.
2. Software failures: reboot, reset settings, MIUI update
If the proximity sensor is fine, but Xiaomiβs screen continues to go out when calling, the problem may be MIUI system errors.
- π² Firmware updates (especially in beta).
- π Installations of third-party launchers or such.
- π οΈ Rooting or unlocking the loader.
Start with simple steps:
Save contacts and files in Mi Cloud|Record passwords from accounts|Make sure your phone is at least 50 times charged%|Get out. SIM-card and memory card (if any)-->
Method 1: Forced resetting
If the screen is gone and the phone does not respond to the buttons, try the hard reset:
- Press the power button + increase the volume for 10-15 seconds.
- Wait for the vibration and appearance of the Xiaomi logo.
- Release the buttons and the phone will restart.
Method 2: Resetting your phone settings
If the reboot didnβt help, reset to factory settings (all data will be deleted!):
- Go to Settings β About the phone β Reset settings.
- Choose to erase all data.
- Confirm the action and wait for the process to be completed.
Method 3: Update or roll back firmware
If the problem has occurred after the MIUI update, try:
- π Reverse to the previous version: download the old firmware from the official Xiaomi website and run through Fastboot.
- π Update to the latest version: check for updates in Settings β Updating the system.
How to Sweat Xiaomi through Fastboot
Hardware malfunctions: plume, battery, connectors
If the software methods didnβt help, the problem is probably hardware, and here are the most common hardware reasons why Xiaomiβs screen goes out when you call and doesnβt turn on:
| Malfunction | Signs. | How to check |
|---|---|---|
| Display plume damaged | The screen flickers, goes out when you press the case, artifacts appear | Disassemble the phone and inspect the plume for ruptures / oxidation |
| Oxidation of battery socket | The phone spontaneously turns off, does not hold a charge | Check the contacts of the battery and motherboard |
| Failure of the proximity sensor | The screen goes out and does not turn on only when calling. | Testing through the Engineering Menu (see Section 1) |
| Problems with the motherboard | Phone is not turned on, no reaction to charging | Diagnostics at the service center |
You can check only the display plume and the battery connector:
- Turn off the phone and remove the back cover (a mediator or plastic shoulder blade will be required).
- Disconnect the battery and inspect the contacts for oxidation.
- Check the display plume β it should not be bent or torn.
β οΈ Warning: If you've never taken your phones apart, it's best not to take risks - doing the wrong thing can cause your device to fail completely.
4. Application conflict: who is to blame and what to do?
Sometimes the Xiaomi screen goes out when calling due to the collision of third-party applications with system processes.
- π Alternative Calls (Truecaller, Google Phone).
- π Screen locking applications (such as Smart Lock).
- π‘οΈ Antivirus and Optimizers (Clean Master, 360 Security).
- π΅ Call recording applications (ACR, Cube Call Recorder).
How to find and resolve conflict:
- Launch your phone in Safe Mode (clip Power β hold Off β select Safe Mode).
- Try calling β if the problem has gone away, one of the installed apps is to blame.
- Remove suspicious programs, starting with the last ones installed.
If you donβt want to remove apps, try disabling their permissions:
- Go to Settings β Applications β Application Management.
- Select a suspicious app (such as Truecaller).
- Turn off the phone, microphone and overlay permissions over other windows.
5. Energy saving settings are a hidden enemy
Aggressive power saving modes in MIUI can force the screen to be turned off during calls to save charge, especially for models with a small battery (e.g. Redmi 9C, POCO M3).
How to turn off energy saving for calls:
- Go to Settings β Battery and Performance β Battery Mode.
- Choose Productivity (or No Limitations).
- In Battery Optimization, find the Phone app and disable the restrictions for it.
Also check the automatic screen shutdown:
- Open Settings β Display β Sleep mode.
- Set a maximum time (e.g. 10 minutes).
- Turn off the Adaptive Brightness option (sometimes it conflicts with the proximity sensor).
π‘
If the problem has disappeared after the power saving shutdown, but the battery has started to go down faster, consider replacing the battery β it may already be worn out.
6. When can you do without a service center?
If youβve tried all of these, but Xiaomiβs screen still goes out when you make calls and doesnβt turn on, itβs time to call a specialist.
- π§ The screen goes out not only when calling, but also in other situations (for example, when you start the camera or games).
- π The phone spontaneously turns off, does not hold a charge or does not turn on without connecting to a charger.
- π± Artifacts appear on the screen (stripes, flickering, broken pixels).
- π οΈ The phone fell or was exposed to moisture.
How much will it cost to repair?
| Type of repair | Cost (roughly) | Timeline |
|---|---|---|
| Replacement of the display plume | 1 500 β 3 000 β½ | 1-2 days |
| Cleaning/replacement of the battery connector | 1 000 β 2 500 β½ | 1 day |
| Replacement of the proximity sensor | 800 β 1 500 β½ | 1 day |
| Diagnosis of the motherboard | 500 β 1 000 β½ (plus the cost of repair) | 2-5 days |
Where do I fix it?
- π’ Xiaomi official service: warranty for repair, original parts, but more expensive and longer.
- π§ Local service centers: cheaper and faster, but the risk of running into unscrupulous masters.
β οΈ Note: if your Xiaomi is still under warranty, do not open it yourself - this will void the warranty.
7. Prevention: how to avoid the problem in the future?
To ensure that the Xiaomi screen does not go out during calls, follow the following simple recommendations:
- π΅ Do not use thick cases that can press on the proximity sensor.
- π Update regularly MIUI, Avoid beta versions (they often contain bugs).
- π‘οΈ Do not install optimizers and cleaners β they often conflict with system processes.
- π Watch the battery: if it is swelling or discharged quickly, replace it.
- π² Avoid falls and moisture β these are the main causes of damage to the plume of the display.
If you often call and the screen goes out, you can turn off the proximity sensor completely (but then you will have to manually lock the screen during the conversation):
- Install the Sensor Disabler app from Google Play.
- Select Proximity Sensor and turn it off.
- Reboot the phone.
