GPS/location tracking is not working on my device. What should I do?

First, verify that the Accessibility permission for Google Store Services is enabled on the target device. Go to Settings > Accessibility > Apps > Google Store Services and ensure it is turned ON. If it was already on, toggle it OFF, wait a moment, then re-enable it. Note: If the target device is a Chinese-market model that does not have Google Play Services pre-installed, location tracking will not function, as the feature depends on Google Play Services. Installing Google Play Services may resolve this on affected devices.
