GPS and Location Services
Modern Android devices like the XT3 no longer simply turn GPS on or off. That’s because most modern
apps use location services as part of their basic functionality. What that means is that positioning has
become an inherent part of most computing devices. Maps depend on it, of course, but also search
engines, voice assistants, cameras, weather, etc., all rely on it, let alone safety and security systems
such as “electronic fences” or “find your device” apps.
GPS and location services have become intertwined. Modern operating systems like Android increas-
ingly regulate access via location and privacy settings, as well as by individual app.

missions the app has, and make changes. The screen images below shows some examples of screens
relating to location services.
Location Service by App
The way GPS and location services are used may
be different from app to app. Before installation,
most apps will request permission to use certain
services. This may include use of Google location
services, Wi-Fi, GPS, device sensor functionality
and more.
In the example to the right, the
GPS Test
app
downloaded from the Google Play Store was
given full location access.
