How to remove random clicks when talking on Xiaomi smartphones: all ways

Why does Xiaomi’s screen respond to random touches during a call?

You're talking on the phone and the screen suddenly reacts to being touched with your cheek or ear - a familiar situation? This problem is common for all Xiaomi touchscreen smartphones, especially models with large displays (like the Redmi Note 11 Pro, POCO X5 The reason for this is the high sensitivity of the sensor, which is necessary for smooth operation of the interface. MIUI, but interferes with calls.

The manufacturer has provided several built-in ways to lock the screen when talking, but they are not always activated by default. Moreover, depending on the firmware version (MIUI 12, MIUI 13 or MIUI 14), the location of the settings may vary. In this article, we will analyze all available methods, from standard functions to hidden features of the engineering menu.

It is important to understand that random taps are not only annoying, but can lead to undesirable consequences, such as accidentally ending a call, activating the hands-free communication or even sending messages. So setting up a lock screen is not just a matter of convenience, but also protection from errors.

Method 1: Enabling screen locking through call settings

The most obvious and safe method is to use the built-in lock-in feature during a conversation, which is available in the standard Phone app on all Xiaomi smartphones with MIUI 12 and later.

1. Open the Phone app (the tube icon on the home screen).
2. Click on the three dots in the top right corner and select Settings.
3. Go to Call Settings (or Calls, depending on version).
4. Find the screen lock option during a call (could be called Accidental Pressing Ban) and turn it on.

Once activated, the screen will automatically lock when you hold the phone to your ear, and you can unlock it only after you complete the call or press the power button. Note that on some models (for example, Redmi 10C), this option may be hidden in the submenu of Additional settings.

Method 2: Using the “Lift to the ear” gesture to block

MIUI has a hidden feature that allows you to lock the screen not only during a call, but also when you hold your phone to your ear, which is useful if you often listen to voice messages or use your phone as a voice recorder, activated through gesture settings:

1. Go to Settings → Display.
2. Choose gestures (or motions in some versions).
3. Find the option to raise to the ear to block (may be called Blocking when lifting).
4. Turn it on and set the delay (recommended 1 second).

Now, when you hold your phone to your ear, the screen will lock automatically, and this method works whether or not the call is coming, so it can be used as a universal solution, but keep in mind that on some models (like the Redmi A2), this feature may conflict with the proximity sensor.

Method 3: Disable the sensor through the engineering menu (for advanced)

If standard methods don't work, you can manually turn off part of the sensor during a call through an engineering menu, which is suitable for advanced users, because it requires care. Incorrect settings in the engineering menu can lead to malfunctions in the screen!

Instructions for Xiaomi on Qualcomm processors (most Redmi and POCO models):

In the menu that opens, select Hardware Testing → Touch Screen and check your sensitivity settings.

⚠️ Warning: Changes to the engineering menu do not persist after the phone has restarted.If the problem has returned, reset or use other methods.

Method 4: Apps to lock the screen during a call

If integrated functions MIUI They can't do it, you can use third-party apps, and they offer flexible settings, like locking only when you call or when you activate the speakerphone.-3 tested:

• 🔒 Call Screen Off is a simple utility that blows the screen when you hold your phone to your ear. It works on all versions of Android, including Android. MIUI. Download to Play Market.
• 📱 Proximity Screen Off – locks the screen using a proximity sensor. Supports delay and exclusion settings for individual applications.

3. Test the work by making a test call.

Method 5: Manually adjust the sensor sensitivity

Some Xiaomi models (especially with the AMOLED-You can manually reduce the sensitivity of the sensor, which will help reduce the number of false positives, but does not block the screen completely:

1. Go to Settings → Display → Additional settings.
2. Find the Sensor Sensitivity (or Touch Sensitivity) section.
3. Move the slider to the left to reduce sensitivity, and the recommended value is 70-80% of the maximum.

If there is no such section, try an alternative path:

1. Install the Touchscreen Calibration app from the Play Market.
2. Start calibrating the sensor and follow the instructions on the screen.
3. After calibration, restart the phone.

Note that too low sensitivity can impair the responsiveness of the screen in normal use, and the optimal balance is when the sensor does not respond to light touches (for example, with the cheek), but works normally when pressed with a finger.

💡

Reducing sensor sensitivity is a temporary solution, and to lock the screen completely when making calls, it's best to combine this with the second or fourth method.

What do you do if nothing helps?

If none of the above methods solves the problem, the reason may be:

• 🔧 Hardware malfunction: Incoming sensor or screen plume is damaged, and this is true if the phone has fallen or been repaired. Check the sensor by calling the phone and covering the top of the screen with your hand -- if the screen is not going out, the sensor is defective.
• 📱 Incompatible firmware – if you use custom software (like LineageOS or Pixel Experience), the lock function may not work properly. MIUI.
• 🔄 Application conflict – some utilities for recording conversations or modifying the interface may block standard features.
