Google’s OK voice assistant may be useful, but on the Xiaomi Redmi Note 9 Pro, it’s often a source of annoyance: pop-ups asking you to set up voice search, random response from phrases in conversation, increased battery consumption — all of which forces users to look for ways to turn off the feature completely.
In this article, we’ll look at all the ways we can deactivate OK Google on the Redmi Note 9 Pro, including hidden MIUI settings, ADB disabling, and even radical measures for advanced users. You’ll learn how to remove intrusive notifications, stop background activity on Google services, and take back control of your device. Importantly, some ways require super-user rights or can affect stability — we’ll honestly warn you of the risks in each section.
Why OK Google is interfering with the Redmi Note 9 Pro
On the Xiaomi Redmi Note 9 Pro (models joyeuse/curtana), the voice assistant is integrated at the MIUI firmware level, which creates several key problems:
- 🔋 Increased battery consumption – Google Play Services constantly listens to the microphone while waiting for the command, even when the screen is off.
- 📱 Slowing down the system – background processes take up 150-200 MB of RAM, which is critical for 6 GB RAM budgetary.
- 🔔 Intrusive notices — MIUI It offers you to configure voice search regularly, even if you’ve never used it.
- 🎤 False positives – the assistant can be activated from random phrases in conversation or music (especially with Russian-language songs).
According to XDA Developers, disabling OK Google on Qualcomm Snapdragon 720G smartphones (as in the Redmi Note 9 Pro) increases battery life by 8-12% by reducing background activity. However, you can’t just remove the Google app — this will lead to malfunctions in the Play Market and other services.
Method 1: Disable via Google Settings (without root)
The safest method that is suitable 90% It does not require superuser rights and does not affect the stability of the system. MIUI 12/13/14 Android-based 10/11/12:
- Open the Google app (the icon with the color letter "G").
- Slip on the profile avatar in the upper right corner → Settings.
- Select Voice Search → Voice assistant.
- Turn off the OK Google slider (could be called Voice Control).
- Go back and select Voice Match → turn off “OK, Google” Recognition.
After this, the assistant will no longer respond to voice commands, but the background processes of Google Play Services will still consume resources.
☑️ Checking the shutdown OK Google
Method 2: Deactivation through MIUI settings
Xiaomi has added hidden options to MIUI to manage Google services, which blocks not only voice search, but background activity as well:
- Go to Settings → Applications → Application Management.
- Click on the three dots in the top corner → Show all the apps.
- Find Google and select it.
- Slip the Permits. → Turn off the microphone.
- Go back and select Battery → Background Activity → Limit.
- In the Notifications section, turn off all switches.
This method reduces battery consumption by 5-7%, but can lead to problems with updating applications through the Play Market.If voice calls on WhatsApp or Telegram stop working after the microphone is turned off, return the permission and use the following method.
💡
If voice messages in instant messengers stopped working after the microphone was turned off, add these applications to the exceptions in the Settings → Privacy → Special Access → Microphone section.
Method 3: Use ADB (for advanced users)
If standard methods don’t work, you can disable OK Google system-level via Android Debug Bridge (ADB), which requires a computer and basic command-line knowledge, but produces 100% root-free results.
Warning: Incorrect ADB commands may disrupt your smartphone. Back up your data via Settings → Additional → Backup and Reset before executing.
- Download ADB Tools and unpack the archive.
- On your smartphone, activate Developer Mode (7 times tap the MIUI version in Settings → About phone).
- Enable USB debugging in Settings → Additional → For developers.
- Connect your phone to your PC and in the command line (in the folder with ADB) do:
adb shell pm uninstall -k --user 0 com.google.android.googlequicksearchboxThis command removes the Google app only for the current user, without affecting system files.
- ✅ Voice search will disappear.
- ✅ Notifications about settings will stop coming OK Google
- ⚠️ Google Play Market and other services will remain operational
- ⚠️ Google Search Widget Will Disappear from Home Screen
What if the ADB can’t see the device?
Method 4: Disconnect via Magisk (requires root)
For users with an unlocked bootloader and Magisk installed, there is a radical method: completely removing Google Assistant components, which provides maximum resource savings, but requires caution.
⚠️ Warning: Incorrectly removing system applications can lead to bootloop (a looped reboot).Be sure you have custom recovery before taking action (TWRP) repair.
- Install the Universal SafetyNet Fix module in Magisk (to pass SafetyNet).
- Download the DisableFlags module from the Magisk repository.
- In the module configuration file (/sdcard/Download/DisableFlags/config.txt), add the lines: com.google.android.googlequicksearchbox com.google.android.apps.googleassistant
- Reset the device.
After application of the module:
| Parameter | Before the blackout | After the blackout |
|---|---|---|
| Battery consumption (per 8 hours) | 18-22% | 10-14% |
| Busy RAM. | 1.2-1.5 GB | 0.8-1.0 GB |
| Background activity | Tall. | Absent. |
| Notifications | Daily | No. |
The downside of the method: some features that depend on Google Services (such as push notifications in games) may not work smoothly.
Method 5: Alternative firmware (for enthusiasts)
If you're willing to go to extremes, installing custom firmware without Google services (GApps) will fix the problem once and for all. Popular options for the Redmi Note 9 Pro:
- 📱 LineageOS – pure Android without unnecessary services
- 🔄 Pixel Experience – firmware in the style of Google Pixel, but with the ability to disable the assistant
- ⚡ Havent OS — Optimized firmware for productivity
- 🛡️ DivestOS – firmware with a focus on privacy (blocks all Google trackers)
Installation process:
- Unlock the bootloader through the Mi Unlock Tool.
- Install custom recovery (TWRP or OrangeFox).
- Sweep through the selected firmware and NikGApps Basic (the minimum package of Google services).
- In the new firmware settings, disable all options associated with the voice assistant.
⚠️ Warning: Installing custom firmware will void Xiaomi's warranty and could lead to data loss.On Redmi Note 9 Pro with Snapdragon processor 720G Some firmware may not support the camera at full capacity (especially night mode).
What to do if OK Google is still available
If after all the manipulations the assistant continues to work, check the following points:
- 🔍 Updates MIUI — After the system update, the settings may reset. Check the firmware version in Settings → The phone.
- 📲 Google Cache – Clear the cache of the Google and Google Play Services app in Settings → Annexes.
- 🔊 Other voice assistants – the Redmi Note 9 Pro can be activated with XiaoAI (Xiaomi voice assistant). → XiaoAI.
- 🔄 Reset settings – in extreme cases, reset to factory settings (don’t forget to make a backup!).
If the problem persists, you may have modified firmware installed on your device with Google services pre-activated, in which case only flashing through Fastboot will help.
