Xiaomi Redmi Note 4 is still one of the most popular budget smartphones due to the reliable hardware and flexible firmware MIUI. However, over time, many users face a problem: the screen either does not respond to light touches, or, on the contrary, it works from accidental touch. 80% of cases are not to blame for hardware failure, but incorrect sensor sensitivity settings that can be reconfigured without contacting the service.
In this article β 5 working methods for changing screen responsiveness, including hidden engineering menus, settings for gloves and calibration through ADB. We will also discuss why after the update. MIUI The sensor can "glut" and how to fix it. All instructions tested on the Redmi Note 4 (mido models mido_global) firmware MIUI 8 before MIUI 14.
Why does the Redmi Note 4 screen react poorly to touch?
Before you change the settings, it is important to understand the root of the problem. The screen sensitivity on the Xiaomi Redmi Note 4 depends on three factors:
- π§ Program settings: sensor parameters in MIUI, enabled mode for gloves or energy saving profiles that limit responsiveness.
- π± Hardware state: wear of the sensor layer (especially after 3-4 years of use), damage after falls or moisture.
- π Updates: After May Updates MIUI 12+ Many users complained about the βstickβ of the screen due to the optimization of gestures.
If the problem occurred after installing custom firmware or resetting to factory settings, most likely, the sensor calibration parameters were lost. βIf the screen does not respond to touch at all, it is a sign of hardware failure (replacement of the touch glass or plume is required).
β οΈ Note: Redmi Note 4 with version MIUI below 10.3.2, the screen sensitivity may not be present in the standard settings. β2 or β3.
Method 1: Standard MIUI settings (the easiest way)
If your smartphone is running MIUI 11 or later, the manufacturer has added a built-in sensitivity regulator.
- Open the Settings β Display.
- Scroll down and select Screen Sensitivity (or Touch Sensitivity in Global Firmware).
- Move the slider to the right to increase responsiveness (recommended 70β80%) or to the left to reduce.
On the Redmi Note 4 with MIUI 9-10, this item can be called Touch gestures or hidden in the Additional section. If there is no controller, move on to the next method.
Fully charge your phone (less than 20% charge can affect sensor performance)
Remove the protective film (which often reduces sensitivity)
Reboot the device (keep Power + Volume up 10 seconds)
-->
After changing the settings, be sure to restart the smartphone - this will allow the system to apply new parameters to the sensor drivers. If the screen has become more responsive, but still "brakes" with quick gestures, try to turn off animation in the developer settings (method). β4).
Method 2: Gloves Mode (if the screen does not respond to light touches)
Gloves Mode is originally designed to work with the screen in cold weather, but it can also be used to increase the overall sensitivity.
- Go to Settings β Display β Additional settings.
- Find the Glove Mode (or Glove Mode) and turn it on.
- If there is no item, enter the βGlovesβ request in the search box for settings.
Once activated, the sensor will respond to even minimal touch, but note: this can lead to false positives (for example, when holding the phone in your pocket). β3).
Yes, regularly |Tryed, but turned it off |No, I didn't know about this feature |My phone doesn't support-->
β οΈ Note: On some custom firmware (for example, LineageOS or Pixel Experience), the glove mode may not work correctly - the screen will stick with prolonged touches. ADB-team (method) β5).
Method 3: Engineering menu (for power users)
Hidden menus allow you to precisely calibrate the sensor, reset it, or test the responsiveness by zone, to get there:
- Open the Phone app.
- Enter the code: ##36446337## (or ##CIT## on global firmware).
- Select the CTP Testing (Sensory Testing) item.
In the calibration menu you will see several tabs:
- π Test Mode β check the responsiveness by zone (useful if the screen reacts poorly only in certain places).
- βοΈ Debug Mode β Manual sensitivity setting (Touch Threshold and Touch Sensitivity options).
- π Reset β reset sensor settings to factory.
For most tasks, reset is enough. If you want to increase sensitivity, change the parameters in Debug Mode:
- Touch Threshold: Set the value 3-5 (the smaller, the more sensitive).
- Touch Sensitivity: Select High or Very High.
What to do if the engineering menu is not opened?
After the changes, be sure to run a test in Test Mode: swipe all areas of the screen. If some areas do not respond (shown in red), this is a sign of hardware malfunction - repair is required.
Method 4: Developer settings (to eliminate delays)
If the screen reacts to touch but with a delay (such as scrolling or playing), the problem may lie in the animation of the interface or performance limitations.
- Activate Developer Mode: Go to Settings β About Phone and click on MIUI Version 7 times.
- Return to the main settings menu and open Additional β for developers.
- Find the items: The scale of window animation β set up 0.5x. Scale of transition animation β set up 0.5x. Debugging by USB β Include (needed for method) β5).
Also in this menu you can turn off MIUI optimization, which sometimes βslows downβ the sensor:
- Find the item "Limit background processes" and set the standard limit.
- Turn off MIUI optimization (if any).
π‘
If the screen reacts too sharply after the changes (for example, double taps work as one), return the animation scale to standard values (1x) Try the method. β3 (engineering menu).
These settings do not directly affect sensor sensitivity, but eliminate software delays that make it seem like the screen is βbraking.β If the problem persists, move to the latter method.
Method 5: ADB-Teams (for advanced users)
If standard methods don't work, you can manually change the sensor settings through the ADB (Android Debug Bridge), which is the most powerful way, but requires a connection to a computer.
You'll need:
- π₯οΈ Computer with installed ADB-driver.
- π± Included Debugging by USB on the phone (see method) β4).
- π Cable USB (preferably original).
Steps:
- Connect Redmi Note 4 to your PC and open the command line (Windows) or terminal (macOS/Linux).
- Enter the command to check the connection: Adb devices must appear serial number of your device.
- Execute the command to increase sensitivity: adb shell settings put system touch_sensitivity 100 (significance 100 β Maximum sensitivity; use moderate effect 70β80).
- Reboot your phone: adb reboot
If you need to reset the sensor settings to factory, use:
adb shell settings delete system touch_sensitivityβ οΈ Attention: Inept use ADB Do not change other system parameters unless you are sure of their purpose. For example, the command adb shell wm density changes the density of the screen and can make the interface unreadable.
π‘
ADB-commands are the only way to change the sensitivity of the sensor on custom firmware (for example, LineageOS or HavocOS), where there is no standard menu. MIUI.
Table: Comparison of sensitivity adjustment methods
| Method | Difficulty | PC required | It's good for MIUI. | Efficiency |
|---|---|---|---|---|
| Standard settings | β | β No. | 11+ | Medium |
| Gloves mode | β | β No. | 8β14 | High (but can give false positives) |
| Engineering menu | ββ | β No. | 8β14 (except for some custom firmware) | Very high. |
| Developer settings | ββ | β No. | All versions. | Low (removes only delays) |
| ADB-team | βββ | β Yes. | All versions (including custom versions) | Maximum |
If neither method worked, the problem is probably hardware.
- π Check the screen for cracks or detachments (even microcracks can disrupt the sensorβs performance).
- π Try connecting your phone to charge β sometimes when the battery is low, the sensor is unstable.
- π οΈ Contact the service center for the diagnosis of the plume or matrix.
