GPS navigation is laggy. How can this be solved?

1. Long press the device's hidden button for 15 seconds to reset it, restoring the device settings to the factory state, so as to avoid positioning delays caused by abnormal configuration.

2. Confirm that the phone's location service is enabled and that the navigation APP has obtained location permission; at the same time, enable the WLAN scanning function, which can improve positioning accuracy.

3. After completing the above settings, reconnect the device and test.

Additional note: Adapter-type products do not have a positioning function themselves; navigation positioning relies on the phone's GPS and other positioning systems.
