1. Why is the mobile phone map navigation signal weak?
The mobile phone navigation prompts that the GPS
 signal is weak. Can not receive GPS satellite signal, can not accurately determine its location. The specific reasons are:
1. The geographical location is remote, and the base station set by the operator is too far away from you, which will affect the signal of your mobile phone. Some common objects in life such as tunnels, houses and even leaves will block the signal, and it will prompt us to go to an open place to detect the signal.
2. The configuration of the mobile phone is low, and the performance of the received signal is weak.
3. High-rise buildings and dense buildings cause occlusion, etc., which will cause the satellite signals received by GPS to change frequently, and sometimes even no satellite signals are received at all.
4. The GPS signal of mobile phone navigation is weak in the car. It may be that the car has a metal film, and the metal particles inside will block the electronic signal.
When the GPS signal is good, the GPS can accurately determine its position by receiving satellite signals, and the position error is less than 10 meters. If the machine has a map, you can mark the corresponding position on the map with a mark.
Second, how to solve the mobile phone map navigation GPS can not locate
GPS can not locate is restricted by many factors, the most important factor is the signal and movement status. GPS is often difficult to locate in places with poor satellite signals (such as indoors, tunnels, and urban blocks with high-rise buildings, etc.), or when in motion. Suggest you:
1. Check whether the GPS function is turned on.
2. Try to locate through the network (data charges may be incurred): slide down the top curtain of the screen – long press the GPS icon – enter the location service setting interface – positioning method – select ‘GPS, WLAN and mobile network’ or ‘Wi-Fi and Mobile Networks’ (operating methods may vary slightly for different models of mobile phones).
3. If it doesn’t work, turn off and restart the phone to re-locate.
4. If you still cannot locate, it is recommended to change to another location or try another time period.
5. Update the software version used. If you cannot locate using the navigation software, update the navigation software to the latest version or try using other navigation software.
If the GPS positioning is still not possible after the above operation, it is recommended that you bring the purchase invoice, warranty card and the machine to the service center for inspection.
