The new features for Fi include a warning on screen if a call is suspected to be spam, which will be handy for those dealing with a deluge of robocalls. There's also the ability to block particular numbers. The features are available on all Fi phones, including iPhones and Android devices.

Other new functions include the ability to call over WiFi to help in locations with poor cell coverage, and an enhanced VPN network for more secure connections. These features were previously only available on selected devices, but now they're available on all Android phones using Fi.

New features are coming to more phones compatible with @googlefi:

☑️ Spam call warnings

☑️ Specific number blocking

☑️ Enhanced VPN network

☑️ WiFi calling
