Google Maps is a maps and navigation app that has recently received an unannounced update. The company has introduced the ability to change the arrow icon of the navigator while driving.

Google hasn’t announced this little update in any way, but it’s been available for iOS beta versions of the app for quite some time. Appeared on Android in stable version 10.52.2.
