How does WiFi improve GPS location

Activate or deactivate GPS - this is how it works with iPhone and Android

The location of your mobile phone is determined via the GPS function. This is necessary, for example, to use a navigation app. For this to work, you have to activate the GPS function.

  3. Tap the icon to enable or disable GPS.
  4. If you hold your finger on the symbol longer, you can make additional settings. This is how you specify for individual apps whether they are allowed to access the location or not.
