You tap and hold the power button on your POCO F6, wait for the assistant to listen, and nothing happens, or you say "Hey Google" across the room and the screen stays silent. It is one of the more frustrating glitches on an otherwise quick phone, because a voice assistant that ignores you is worse than no assistant at all. The good news is that the POCO F6 officially supports Google's voice assistant through its pre-installed Google services, so when it stops responding the cause is almost always a setting, a stale app, or a power-saving rule rather than broken hardware. Work through the fixes below in order, starting with the quickest and safest, and you will usually have it talking again before you reach the bottom.
One thing to know up front is that the POCO F6 does not have its own POCO-branded assistant. The "voice assistant" here is Google's, and the phone can run either Google Assistant or Gemini. Knowing which one you actually want is half the battle, so keep that in mind as you go.
Start With A Restart And A Real Connection
Google's official troubleshooting is blunt about this, because the assistant needs connectivity to respond. Before you change a single setting, confirm your POCO F6 has a strong internet connection and restart it if needed. A weak signal or a dropped Wi-Fi link will make the assistant look broken when it is simply offline.
Switch from Wi-Fi to mobile data (or the other way) to rule out one bad network, then restart the phone normally and try your voice command again. This clears temporary glitches and re-establishes the connection the assistant relies on, and it resolves the problem surprisingly often on its own.
Make Sure The Right Assistant Is Set As Default
Because the POCO F6 can run either Google Assistant or Gemini, a common reason voice commands "stop working" is that the wrong one got set as the default, or it switched without you noticing. Decide which assistant you want active, then point the phone at it.
To set Gemini as your default, use either of these official paths.
- 1.Open the Settings app, scroll down to find and tap Google, then go to All services > Search, Assistant & Voice > Google Assistant > Digital assistants from Google, and choose Gemini.
- 2.Or open the Google app, tap your profile picture or initial in the top right, then go to Settings > Google Assistant > Digital assistants from Google > Gemini.
If you would rather go back to the classic Google Assistant, open the Gemini app, tap your profile picture or initial in the top right, then tap Switch to Google Assistant > Google Assistant > Switch. Either way, once one is set as the default, saying "Hey Google" or activating the assistant by touch (such as pressing and holding the power button) will trigger that assistant to respond.
Turn On Hey Google And Teach It Your Voice
If hands-free activation is what is failing, the problem is usually that "Hey Google" or Voice Match is switched off. These are what let the phone listen for your voice and respond without you touching anything.
- 1.Open the Google Home app.
- 2.Go to Settings > Google Assistant > Voice Match.
- 3.Turn on "Use Voice Match in this home."
- 4.Turn on "Hey Google." If it is greyed out, turn on Google Assistant first, then come back and enable it.
- 5.Follow the prompts so it learns your voice.
Completing the voice-learning prompts matters, because that is what actually enables hands-free activation, and skipping it leaves the phone unable to recognize you.
Let The Assistant Work On The Lock Screen
Sometimes the assistant only refuses to respond when the phone is locked, which points to a single setting rather than a broken feature. Turn on the "Assistant on lock screen" setting so it can answer without you unlocking first.
If you prefer to keep "Hey Google" disabled, you are not stuck, because Google notes you can always open the assistant by touching and holding the Home button. That gives you a reliable manual trigger even when voice activation is off.
Update The Google App
An out-of-date Google app is one of the most common reasons voice features break, and it is one of the easiest to fix. Open the Google Play Store, go to the Google app page, and tap Update. Once the update finishes, reopen the app and test a voice command to confirm the feature is back.
Confirm The Assistant Language Matches What You Speak
If the assistant hears you but never seems to understand, the assistant language may not match the language you are actually speaking. A mismatch here stops it from recognizing commands even when everything else is set up correctly.
Open the Google Home app, go to All settings > Languages, and check that the assistant language is the one you speak. Correct it if needed, then try a command again to verify it now responds.
Stop Power Saving From Muting The Assistant
Power-saving features can quietly suspend the background listening the assistant depends on, so the phone simply stops responding to "Hey Google" until you wake it manually. Two settings are the usual culprits.
Open the Settings app, go to Battery, then turn off Battery Saver and turn off Adaptive Battery. With both off, test "Hey Google" again. If the assistant suddenly responds, one of these was the cause and you can decide whether to leave them off or accept the trade-off.
Retrain Voice Match And Cut The Background Noise
If the assistant still misses you, the issue may be how it is hearing your voice rather than the settings. Say "Hey Google" in a normal, conversational tone instead of shouting or whispering, and move somewhere quieter so background noise is not drowning out the trigger.
If it continues to ignore you, re-do Voice Match so Google can recognize your voice again. Retraining gives the assistant a fresh, clean sample of how you actually sound, which often fixes recognition problems that built up over time.
Install The Latest Xiaomi HyperOS Update
The POCO F6 runs Xiaomi HyperOS, and a pending system update can resolve microphone or assistant bugs that no app-level change will touch. Keeping the software current is one of the more reliable long-term fixes.
Go to Settings > About phone > Xiaomi HyperOS > Check for updates, then install anything offered. Use a stable network and keep the phone well charged before you start, and do not interrupt the update once it begins. When it finishes and the phone reboots, test the assistant again.
Force Restart, And Only As A Last Resort A Factory Reset
If the phone has frozen and nothing responds, including the assistant, force a restart before anything drastic. Press the power button for more than 10 seconds to force restart the POCO F6, then let it boot and test the assistant again.
If the voice assistant still fails after every step above, a factory reset is the final software option, but treat it as a genuine last resort. Performing a factory reset will erase all data on your phone, so make sure to back up any important data before proceeding.
- 1.Go to Settings > About phone > Factory reset.
- 2.Tap Erase all data.
- 3.Choose whether to Back up first (do this if you have not already).
- 4.Confirm and perform the Factory reset.
When the phone restarts, set up Google Assistant or Gemini and Voice Match from scratch using the earlier steps. If even a clean reset does not bring the assistant back, the problem may be hardware, and the right move is to take the phone to a Xiaomi authorized after-sales or service center for inspection.
Frequently Asked Questions
Does the POCO F6 actually support a voice assistant?
Yes. The official POCO F6 FAQ confirms the phone supports Google Voice Assistant and ships with pre-installed Google services. There is no separate POCO-branded assistant, so the voice assistant is Google's, and the phone can run either Google Assistant or Gemini.
Why does "Hey Google" work for someone else but not for me?
That usually means Voice Match was trained on a different voice, or your own voice profile needs refreshing. Re-do Voice Match in the Google Home app under Settings > Google Assistant > Voice Match so the phone learns to recognize you again, and speak in a normal conversational tone in a quieter spot when you test it.
Will turning off Battery Saver hurt my battery life much?
Power-saving features can suspend the background listening the assistant relies on, which is why turning off Battery Saver and Adaptive Battery in Settings > Battery often restores "Hey Google." If the assistant starts working again afterward, you can decide whether to leave them off or re-enable them when you do not need hands-free voice.
Is a factory reset safe to try for this problem?
It works, but it is a last resort because it erases all data on your phone. Back up anything important first, then go to Settings > About phone > Factory reset > Erase all data and follow the prompts. Only do this after every other fix has failed.
What if the phone still will not respond after a factory reset?
If a force restart and a full factory reset both fail to bring the assistant back, the issue may be hardware rather than software. Take the POCO F6 to a Xiaomi authorized after-sales or service center so it can be inspected.
