The Xiaomi Redmi 9 is one of the most popular budget smartphones, but many users face the problem of low vibration, especially when calling, notifications or games where tactile feedback plays a key role. Unlike flagship models, where the vibrator motor is more clearly set, in Redmi 9, its work often leaves much to be desired.
The causes of low vibration can range from the software constraints of MIUI to the hardware features of the model. Fortunately, there are several ways to increase response, whether through standard settings or through hidden features or third-party tools. In this article, we will discuss all working methods, including those that do not require root rights, and those that require deeper intervention in the system.
It is important to understand that excessive vibration can lead to overheating of the engine or increase battery consumption, so before changing the parameters, read the warnings in the appropriate sections.
1. Check the basic vibration settings in MIUI
Before you resort to radical measures, make sure that the vibration is on and configured correctly in the standard settings of the system. In Xiaomi Redmi 9, several menus are responsible for this:
- ๐ฑ Sound settings: go to Settings โ Sound and vibration โ Vibration. You can turn on the response when you touch, type and unlock.
- ๐ Notifications: in the Settings section โ Notifications check if vibration is enabled for specific apps (such as WhatsApp or Telegram).
- ๐ฎ Game Mode: If the vibration is weak in games, go to Settings โ Special facilities โ Game turbo mode and disable restrictions on tactile feedback.
Notice the Vibration Intensity slider -- some MIUI firmware has it hidden, and if it's not there, your version of the software doesn't support manual adjustment through the standard menu, so move on to the following.
โ ๏ธ Note: If after the update MIUI The vibration is gone completely, try resetting the sound settings to the factory. โ System system โ Resetting settings โ Reset the sound settings.
2.Use of the engineering menu (without root)
The engineering menu is a hidden section of Android where you can fine-tune hardware components, including the vibrator motor. On Xiaomi Redmi 9, it is accessed through a special code:
- Open the phone app.
- Enter the combination: ##4636###.
- In the menu that appears, select Hardware Testing.
- Find the "Vibrator" section and tap it.
Here you'll see the vibration parameters, including amplitude and duration, and depending on the firmware version, the interface may vary:
- ๐ง Amplitude: Increase the value from 50โ70 to 80โ90 for a stronger response.
- โฑ๏ธ Duration: Increase the vibration time (e.g., from 200 ms to 400 ms).
- ๐ Tap "Test Vibrator" to check for changes.
On some MIUI 12+ firmware, the engineering menu may be blocked. If the code doesn't work, try an alternative method through the MTK Engineering Mode app (available on Google Play for MediaTek-based devices).
3. Specialized applications for vibration enhancement
If standard methods don't work, you can use third-party utilities that run on top of the system and allow you to flexibly configure tactile feedback.-3 tested applications:
| Annex | Functions | Need root? | Reference |
|---|---|---|---|
| Vibrator Strength | Vibration Intensity Adjustment for Notifications, Calls and Touches | No. | Google Play |
| Good Vibrations | Creating custom vibration patterns, testing the motor | No. | Google Play |
| MacroDroid | Automation of vibration by triggers (for example, with low battery charge) | No. | Google Play |
Example of settings in Vibrator Strength:
- Install the app and grant permissions to access notifications.
- In the Global Vibration section, move the slider 80-90%.
- Enable the option "Override System Settings" (redefinition of system settings).
- Restart your phone to apply the changes.
โ ๏ธ Note: Some applications (e.g. Good Vibrations) may conflict with energy saving modes MIUI. If the vibration is unstable, add the utility to the exception list in Settings. โ Battery โ Optimizing the battery.
Install the app from the official store |Give all the permissions requested |Disable battery optimization for the utility |Reboot the phone after settings-->
4.Configure via ADB (for power users)
If you're ready for more in-depth manipulation, you can change the vibration settings through the Android Debug Bridge (ADB), a method that doesn't require root rights, but requires command-line operation.
Steps to increase vibration:
- Turn on USB debugging on your phone: Settings โ About Phone โ MIUI version (tap 7 times to activate Developer Mode), then go back to Settings โ Additional โ Developers โ Debugging on USB.
- Connect Redmi 9 to your PC and confirm debugging permission.
- Open the command line (Windows) or terminal (macOS/Linux) and type:
adb shell settings put global vibration_intensity 3Where 3 is the intensity level (you can set values from 1 to 5). To apply the changes, restart the device.
To return the standard settings, do:
adb shell settings delete global vibration_intensityWhat if the ADB does not recognize the device?
5. Modification of system files (root required)
Root rights are required to maximize control of the vibrator, a method that is only suitable for experienced users, as improper actions can lead to loss of warranty or damage to the system.
Instructions:
- Get root access with Magisk or SuperSU.
- Install a file manager with root support (such as Root Explorer or FX File Explorer).
- Cross the path: /system/vendor/etc/vibrator_capability.xml.
- Find the lines with the parameters max_amplitude and resonant_frequency. Change the values to:
<int name="max_amplitude" value="255" />
<int name="resonant_frequency" value="200" />Save the file, set the rights to 644 (r-w-r--r---) and restart the device.
โ ๏ธ Warning: Changing system files can lead to bootloop ( looped boot).Before editing, back up the original file and make sure you have access to the original file. TWRP repair.
๐ก
Before obtaining root rights, check if your version of MIUI supports bootloader unlocking. On some firmware, Xiaomi blocks this feature without official permission through the Mi Unlock Tool.
6. Hardware causes of weak vibration and their elimination
If the software methods didn't work, the problem could be in the hardware, and here are the most common reasons and ways to fix them:
- ๐ Wear of vibrator: Over time, the part loses its efficiency due to dust or mechanical damage. The solution is to replace the motor (cost of the part: ~300-500 rubles).
- ๐ Bad contact: Oxidation or contact loss on the board. Check the connection of the vibrator motor to the motherboard (requires disassembly of the phone).
- ๐ Energy saving: In the mode of "Ultra-savings" MIUI Limit vibration. Turn off this mode in Settings. โ Battery.
- ๐ ๏ธ Factory marriage: If the phone is new and the vibration is weak out of the box, contact the service center for warranty.
To diagnose hardware problems, you can use the equipment test:
- Enter the code ##6484## (Manual Test Mode) in the phone application.
- Select "Vibrator" and check the engine at different frequencies.
- If the vibration is absent or intermittent, the problem is precisely in the โironโ.

Before disassembling the phone, make sure the vibration is not turned off at the software level. Often users confuse the hardware malfunction with MIUI bug firmware.
7. Alternative ways to improve tactile feedback
If you canโt increase the vibration, you can go another way โ make it more noticeable due to additional triggers:
- ๐ Sound notifications + Vibration: The combination of sound and tactile response makes it more likely that you won't miss an important message. โ Sound. โ Notification scheme.
- ๐ฑ Light indication: Turn on the screen blinking or LED-If you have any, use the Light Flow app to do this.
- ๐ต Custom melodies: Set unique sounds for different contacts โ this will help distinguish important calls even in low vibrations.
- ๐ค Automation: With Tasker or MacroDroid, set the vibration to re-vibrate 2-3 seconds after the first signal.
For games, you can use tactile feedback gamepads connected via Bluetooth, for example, Xiaomi Game Controller or Sony DualSense transmit vibration directly to the hands, removing the load from the phone.
