Google Now was supposed to help us all exist in a futuristic utopia where we carried our own permanently available assistants in our pockets. But instead, many Android users have found that the feature has just left them repeating the phrase 'OK Google' over and over again in to an unresponsive phone, no doubt drawing some strange looks in the process.
But don't despair just yet, there are a few simple fixes you can try that should get the voice recognition software working and keep your thumbs free from the risk of repetitive strain injury.
1. Watch your language
Google Now currently only responds to US English. Although this will be the default language for many users, it's still worth checking in the Language section of your phone's Settings menu and altering as required. Updating your language pack may also solve your problem. Go to Voice > Search Language Settings > Offline Speech Recognition >English (US) > Update Available.
2. Check the microphone
As a voice-based system, Google Now relies on uninterrupted access to your smartphone's microphone. When you open the Google app, the microphone icon on the right hand side of the search bar should appear bold, with fully-formed lines. If it has a dotted line, you may have a problem with your microphone.
This may be caused by debris in the small microphone hole often found next to the charging port – have a careful poke around with a safety pin or similar to clear it out and you'll often fix the problem. If that doesn't work, check the microphone settings within the Google app.
Occasionally, apps running in the background are making noises which may interfere with the microphone picking up your voice, so check these too – and close any that you think may be making a sound.
3. Disable S Voice
Although there is no clear reason why, it appears as though Google Now and the S Voice feature on Samsung phones like the S6 and S6 Edge are not always compatible. If you have a Samsung with S Voice installed and would prefer to use Google Now, your best bet might be to remove S Voice from your device entirely.
4. Rule everything out
This may be stating the obvious but the feature does need Wi-Fi or data to operate, so make sure your device is connected before you try a search. Also, and this is probably the oldest advice in the book, it never hurts to do a quick reboot – sometimes magic really does happen.
5. Re-train OK Google
Sometimes, for reasons unknown, Google Now doesn't retain the commands you have given it. If all else fails, it might be time to re-train your digital companion.
In order to do this, you'll need to go to the Google Settings App, locate the Search & Now option, followed by Voice then OK Google detection. Now just hit Retrain Voice Model and say "OK Google" three times, as you did when you initially set it up.
