Enable or Disable Emergency Location Service (ELS) auf OnePlus
Emergency Location Service (ELS) is a network feature built into OnePlus phones running OxygenOS. When you place an emergency call in a region where ELS is supported, your phone can transmit your current location to emergency services automatically, regardless of your regular location settings.
This is why ELS can briefly turn on Google Location Services during an active emergency call, even if you normally keep them disabled. Once the call ends, your previous location settings are restored. This behavior is intentional and designed to help responders find you faster in a real emergency.
If you want to check or change this setting, open Settings ➔ Location ➔ Advanced ➔ Emergency Location Service and toggle Send ELS Location.
Turning this off does not disable emergency calls themselves. It only stops the automatic location transmission tied to those calls. Consider leaving it enabled unless you have a specific privacy reason to disable it, since it only activates during genuine emergency dialing.
If your concern is regular background location tracking rather than emergency calls, that is controlled separately under standard app permissions and has no connection to this ELS toggle.
