There are a few ways to make Google Maps the default map app on Android. The first way is to install the Google Maps app from the Google Play store. The second way is to use a third-party map app such as MapBox or OpenStreetMap. The third way is to use a custom launcher that includes Google Maps as the default map app. The fourth way is to set up a home screen shortcut for Google Maps. This shortcut can be found in the launcher’s settings and should be set as the primary shortcut.
