When your Fairphone 5's voice assistant stops responding, it can feel like a step backwards. Whether you're using Google Assistant or another option, getting it working again is usually straightforward. Let's run through the most effective fixes.

Start With a Quick Restart

Before diving into settings, give your phone a fresh start. Press and hold the power button for about 10 seconds until the screen goes black and the device restarts. This clears temporary glitches that can affect the microphone or assistant service.

If the standard restart doesn't work, you have another option thanks to the modular design. You can power down the phone, pop off the back cover, and remove the battery for 30 seconds before reinserting it. This is a more complete power cycle.

Verify Your Assistant is Enabled and Set Up

Open your Settings app and head to Apps > Default apps > Digital assistant app. Make sure your preferred assistant, like Google, is selected here.

Next, go to Settings > Google (or search for "Assistant settings"). Tap on "Hey Google & Voice Match" and ensure "Hey Google" is toggled on. If it's off, turn it on and follow the prompts to retrain the voice model.

Check for Microphone Blockages

The Fairphone 5's microphones can be obstructed by a case, dirt, or even a screen protector that wasn't aligned perfectly. Check the small pinhole microphone ports along the edges of the phone.

Gently clean them with a soft, dry brush or a blast of compressed air. Avoid using anything sharp or wet that could push debris further in or cause damage.

Review App Permissions and Battery Optimization

Your voice assistant needs permission to use the microphone. Go to Settings > Privacy and security > Permission manager > Microphone. Find your assistant app (e.g., Google) and make sure it's allowed.

Android's battery saver features can sometimes restrict background processes. Go to Settings > Battery and check if any form of power saving is active. Also, find your assistant app in the app battery settings and set it to "Unrestricted."

Disable Conflicting Accessibility Features

Certain accessibility services can interfere with the "Hey Google" hotword. Go to Settings > Accessibility and look at the list of installed services.

If you have any screen readers or sound detectors enabled, try temporarily turning them off to test if your voice assistant starts working again. You can always re-enable them later.

Update Your Apps and System Software

An outdated Google app or Play Services can cause voice features to break. Open the Play Store, tap your profile icon, and go to Manage apps & device > Updates available. Update the Google app and Google Play Services.

It's also wise to check for a system update. Fairphone promises excellent long-term support, so bugs are often patched. Go to Settings > System > System update to check.

Clear the Assistant App's Cache and Data

Corrupted cache files can cause all sorts of odd behavior. Go to Settings > Apps > See all apps. Find and select the Google app (or your primary assistant).

Tap Storage & cache and then Clear cache. Test the assistant. If it's still broken, you can tap "Clear storage" or "Manage space" > Clear all data. Note that this will reset the app and you'll need to set up "Hey Google" again.

Ensure a Stable Network Connection

While some basic commands process on-device, many voice assistant requests require an internet connection to fetch answers, control smart home devices, or fetch directions. Check that you have a strong Wi-Fi or mobile data signal.

Try asking your assistant something simple that works offline, like "set a timer for 5 minutes." If that works but web queries fail, your network is likely the issue.

Test With a Different Language or Accent

Sometimes the voice recognition model struggles with specific accents or dialects. As a test, go into your assistant's voice settings and temporarily switch the language to a different option, like English (US) if you're using English (UK).

See if the assistant responds more reliably. If it does, you can switch back and try retraining the voice model in your preferred language, speaking very clearly during the setup phrases.

Reset App Preferences or Perform a Software Reset

If all else fails, you can reset all app preferences without losing personal data. This reverts app permissions, default apps, and background restrictions to factory defaults. Go to Settings > System > Reset options > Reset app preferences.

As a last resort, a full settings reset can clear deep configuration errors. In the same Reset menu, choose Erase all data (factory reset). Remember, this will wipe your phone completely, so ensure everything is backed up first.
