Microsoft has released an update for its Cortana Android app enabling the voice assistant to be triggered by holding down the home button.
According to Microsoft News the new feature enables Microsoft's assistant to pre-empt Google's own Google Now voice assistant, meaning that you can choose which robot helps you out.
The only downside is that the app doesn't yet support voice activation like Google Now, apparently due to hardware compatibility issues - so for now you're going to have to stick to using your fingers to get Cortana talking.
The increased push for Cortana on Android follows the launch of Windows 10 a couple of weeks ago. The new OS, which will eventually roll out to desktop, tablet and mobile has Cortana baked in at its core and enables users to ask questions, set reminders and make notes using their voice.
