Owners of Xiaomi, Redmi and Poco smartphones often face a situation where the display reacts to random touch or continues to work in the pocket.This can be due to too high sensitivity of the matrix, software failures or simply features of the MIUI and HyperOS shell. Sometimes the user needs to completely ignore any touch, for example, when watching videos in his pocket or to prevent accidental calls during sleep.
Fortunately, there are several ways to limit or completely deactivate the touchscreen response in Android and its Chinese-branded add-ons. The standard settings menu does not have a single “Switch off screen” button, so you will have to use hidden features or third-party software. The choice of the specific method depends on your goal: whether you want to temporarily lock the device or you need to fix a software bug.
Next, we’ll look at all the options available, from simple settings to advanced methods for power users, and it’s important to understand that completely disabling the touchscreen with software can make it impossible to control the phone before you restart, so be careful when you follow the instructions.
Using Developer Mode to Block Input
One of the most effective built-in ways to limit screen response is to use a developer menu, and you can find settings that change the behavior of the touch layer, and to get there, you have to quickly click seven times on the build number in the About Phone section.
Once you activate the hidden menu, go to Settings → Advanced Settings → Developer. In this list, look for the option associated with the pointer or multi-touch. Although there is no direct “disable” button here, you can change the settings so that the system will no longer handle the touch correctly.
- 📱 Find the “Show Touch” item and turn it off if it’s active to remove the extra load on the processor.
- ⚙️ In the Enter section, try changing the animation speed, which indirectly affects the system’s perception of swipes.
- 🔒 Use the “Do not turn off screen” function only when charging to avoid locking confusion.
It's worth noting that these settings are primarily designed to debug applications, but they give the user deep control over the touch layer. Be careful: changing some parameters can lead to unstable interface operation.
⚠️ Note: Experiments in the developer menu can lead to unpredictable behavior. Remember or photograph the original values before making changes.
Application of third-party applications to lock the screen
If there's not enough built-in tools, Google Play apps come to the rescue, creating a transparent layer over the desktop that intercepts all touches, preventing them from reaching the system, ideal for parents or for protection from pocket calls.
Popular programs like Touch Lock or Screen Off Pro allow you to block the sensor by timer or button, and once activated, the screen can burn, but the phone will not respond to any touch of your fingers.
☑️ Selection of a locking application
The main advantage of this approach is that it can quickly return control of the device, which usually requires you to press a combination of volume buttons or make a movement known only to the owner, which provides a balance between convenience and protection from random actions.
However, it is worth remembering that third-party programs require permissions to access the system, which can affect the autonomy of the Xiaomi smartphone.
Locking through ADB-Teams for Advanced Users
For those who are not afraid of the command line, there is a method to disable the touchscreen driver through USB debugging. This method requires connecting the phone to a computer and installing ADB drivers. It allows you to programmatically kill the process responsible for handling touches.
First, enable USB debugging in the developer menu. Then connect the phone to your PC and type in a command to find the device. Make sure the connection is successful before you go on to enter commands.
adb shell input touchscreen disableThis command turns off touchscreen input. To get it back, you use the adb shell input touchscreen enable command, which is the most radical method that actually turns off the physical touchscreen module at the software level.
| Team team. | Action. | Necessary rights |
|---|---|---|

| input touchscreen enable | Touchscreen switching on | ADB / Root |

What if the ADB can’t see the phone?
Setting up the “In the pocket” mode and sensors
Often, the problem is not solved by turning off the screen, but by properly configuring the sensors that detect the phone in your pocket. The MIUI shell has a Mode in Your Pocket feature that locks the screen when an object approaches the top end of the device.
Check the settings in Lock and Protect → Mode in your pocket. Make sure the switch is activated. If the proximity sensor is contaminated or closed with a protective film, the function may not work properly and the screen will light up unnecessarily.
- 🧼 Wipe the top of the screen and the speaker area from dust and grease.
- 🛡️ Check if the protective glass is blocking the proximity sensor.
- 🔧 Calibrate the sensors through the engineering menu by dialing code ##6484##.
If the sensor is working, but the screen still responds to friction, try to reduce sensitivity or use a case with higher sides. This will physically limit the contact of the fabric with the surface of the display.
⚠️ Note: When using thick protective glasses or magnetic fastener covers, the proximity sensor may not work properly, leading to false lock positives.
💡
To check the proximity sensor, use the Test app (CIT) in the Xiaomi engineering menu. Hold your palm to the top speaker - the screen should go out.
Solving problems with "phantom" touches
Sometimes users are looking for a way to turn off the touch because the screen is "living its life," a phenomenon called "ghost touch," often caused not by software settings but by physical factors, in which case software blocking will only hide the symptom, but will not cure the disease.
The cause may be static electricity, poor contact with the display plume or the use of a poor-quality charger. If the screen starts to “fear” during charging, replace the power supply or cable with the original Xiaomi accessories.
It's also worth checking if the device is overheating. High temperatures can cause malfunctions in the capacitive layer, leading to chaotic pressing. Let the phone cool down and remove the case if it interferes with the heat sink.
If the problem persists after resetting and checking in safe mode, it is likely that a touchscreen or display module will need to be replaced, in which case software methods will not help.
Use of Do Not Disturb Mode and Game Profiles
Do Not Disturb mode can be used to temporarily limit responses to notifications and random swipes, although it does not turn off the touchscreen completely, it prevents the screen from turning on when messages arrive, which reduces the risk of accidental tapping in the dark.
Owners of Black Shark series gaming smartphones or models with Game Turbo function can use the game mode. In its settings, there is often an option to lock the navigation buttons and the edges of the screen, which prevents you from leaving the game when you accidentally touch.
Activate game acceleration through the Security app and set up a profile for the app you want, which will block the side areas of the screen and system gestures, leaving the center part active.
💡
The combination of Do Not Disturb and Game Mode gives maximum protection against accidental interruptions and presses while using multimedia.
