Why does the navigation always show the weak signal of the location?

1. Check the location service and permission settings of your phone.

Go to Settings - Security & Privacy - Location Services, make sure the location services of your phone are turned on, and make sure that the location permissions of third-party apps are turned on. For models that support setting the positioning mode, please set it to: Accuracy.

High. Note: Android and above models do not display the location mode setting option, which does not affect the actual use of the positioning function.

2. Check whether there is signal occlusion at the location.

In high-rise buildings, indoors, valleys, tunnels and other places with serious occlusion, GPS signal reception will be affected, resulting in inaccurate positioning, it is recommended to move to an open place for use and observation.

3. Confirm whether to use third-party magnetic or metal accessories.

Please check whether you use metal protective shells, magnetic protective cases, magnetic brackets and other accessories, metal and magnetic materials.

It is easy to interfere with and shield the reception of GPS signals, so it is recommended that you remove the accessory and relocate it.

4. Check whether it is affected by third-party virtual positioning software.

Effect. Please check whether there is third-party virtual location software or punch card software installed on your phone, and if you are using such software, please restart your phone or uninstall the software to locate the location.

5. Comparative test verification.

In the driving scenario, when the car is in the starting state, if the navigation signal in the car is weak, you can move outside the car to compare and observe the navigation signal strength, and check whether it is affected by the interference of electronic devices in the car or the car glass film. In addition, use different map software to determine whether it is due to the software itself.

6. Upgrade the system version.

Please upgrade your phone to the latest version to view.

7. Service center testing.

If the above methods fail to solve your problem, please back up your mobile phone data in advance, bring your mobile phone and purchase voucher to vivo customer service center for testing, pay attention to WeChat *** "vivo" or "vivo customer service" to inquire about the service center address**, it is recommended to contact before going to ensure that there is a staff reception before going over, so as to avoid delaying precious time and running in vain.

If you are using a Huawei phone, please try the following methods to check and confirm:

1.Please check if your phone settings are correct.

1) Please make sure that the mobile network connection is normal and the location information is enabled in the drop-down notification bar.

2) Please confirm that the location service settings of your phone are correct. Steps: Pull down the notification bar, press and hold the location information icon to enter the location service interface, click to improve accuracy, and enable Wi-Fi scanning to improve the accuracy of network positioning.

3) Make sure that the navigation software has permission to read the location information. Steps: Open the phone settings, enter permission management in the search bar to enter the permission management interface, click the app that cannot locate the navigation, and turn on the location information permission.

2.Reasons for geographical location.

1) Towering buildings, dense buildings, roofs, and walls will affect the reception of GPS signals and lead to inaccurate positioning. We recommend that you enable Wi-Fi or move to an open area.

2) The signal is usually poor in tunnels, viaducts, mountainous areas and other heavily obstructed places or high-speed driving scenarios, and the GPS signal can be recovered when you go out of the area. If the GPS signal has been poor, it is recommended that you try restarting your phone.

3.Other influencing factors.

Metal or magnetic materials will interfere with and shield GPS signals and affect the reception of signals. If you're using a metal case, magnetic case, magnetic stand, or magnetic chuck, we recommend that you remove it and reposition it.

If the above methods still do not solve your problem, we recommend that you back up your data in advance (WeChat QQ and other apps must be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for testing.

As we all know, from sending to receiving, a signal requires several conditions: signal source, propagation medium, receiver.

Let's talk about this problem from three aspects: signaling, propagation, and acceptance.

1.If the signal source is missing, the GPS signal is weak.

GPS positioning, in fact, is to determine the position of the GPS receiver through four satellites with known positions. In principle, three stars can achieve the most basic positioning, and the fourth star serves as an auxiliary. The more stars the public often says, the more accurate the positioning!

Look, if there are fewer stars passing by in the sky above the location, or even no stars in the sky, and even the source signal is missing, it must indicate that the GPS signal is weak!

In addition, when the GPS system is debugged, the main system is upgraded, and there are stars passing by, but people are not working, and there are no stars, which will prompt that the GPS signal is weak!

2.Obstacles in signal propagation indicate that the GPS signal is weak.

The source signal is very strong, but in the propagation, it is better than the shielding, and the receiver cannot receive the signal, which will inevitably indicate that the GPS signal is weak.

Common situations for people, such as in tunnels, shielded rooms, under overpasses. These are typical scenarios where the GPS signal is weak due to shielding.

In addition, when the weather is abnormal, there is a problem with the transmission medium, and there is also a situation where the GPS signal is weak.

Why do some navigators always prompt weak GPS signals?

3.If there is a problem on the receiving end, it will indicate that the GPS signal is weak [software and hardware].

Hardware situation. If there is a problem with the receiving device, such as the antenna is damaged, the battery is about to run out, the GPS function module is damaged, the circuit connecting the CPU to the GPS is short-circuited, etc., it will also indicate that the GPS signal is weak or no signal!

Software situation. Conflicts between navigation software and other software can lead to error situations, which are generally rare and can be ignored.

To sum up, these are the reasons for a weak GPS signal.

Hello dear! I don't know if you're navigating a car or a mobile phone. I will give you a separate analysis as follows:

There are several reasons why the car navigation signal is weak, and there are generally the following reasons:

1. There is a problem with the navigation itself, change the baud rate and com port from the new. This setting depends on your machine itself, you can consult the merchant who installed the navigation for you.

2. The film contains too much metal and shields the signal, and the satellite receiving module of general navigation is placed in the A-pillar, or on the top of the rearview mirror, and there is no film in these two places, which will not shield the signal.

3. There is a problem with the navigation module itself, such as the antenna interface is loose or too tight, and then there is a problem with the hardware of the navigation module itself.

Mobile phone navigation signal is weak, most of them come from the communication base station and mobile phone belt and other problems, the main problem is caused by the communication base station problem, the current national 5G base station has covered more than 97% of the counties, but the more remote the base station, the signal will be weakened, after all, the signal is also a wave, the distance and the ground and underground, the penetration intensity is not the same.

The strength of the signal is related to the location and the coverage radius of the base station! Of course, it is not excluded that it has something to do with mobile phones, such as the previous baseband problem of Apple's mobile phone, which will also cause a weak mobile phone signal, not to mention a weak navigation signal.

Hope it helps!

1.First of all, in terms of hardware, the mobile phone is disassembled to find the GPS antenna, 1+5 is the two inclined yellow ** above the camera, if you don't know how to go to the mobile phone, the repair shop calls the boss to go, and then carefully use tweezers to straighten the GPS antenna, pay attention not to break it too hard2The software is convenient, you can change the config file of a mobile phone GPS, or the next GPSPRO module.

The weak signal of the satellite may be a problem with the map version, or it may be a problem with the mobile phone itself, a problem with settings, a network problem, a signal problem, a weather problem, and so on.

As long as it doesn't affect navigation, I never care about it.

Hello, I have seen your question and am sorting out the answer, please wait a while

Hello, I am happy to answer this question for you, the main reasons for the weak positioning signal of the mobile phone are: 1. Your current geographical location is remote, and the base station set by the operator is relatively small, which affects the signal of the mobile phone, you can try it in a place with a good signal; 2. The configuration of the mobile phone is low, but this kind of situation is relatively rare. There are several ways to solve this type of problem:

1. Go to Settings - Location Information - Turn on the location information, and set it to "High Accuracy", and then go to a place with a wide field of vision to re-navigate. 2. Shut down and restart, change the SIM card to connect to the data network. 3. Close some programs in the background, clean up the garbage on the phone, and keep enough memory space to operate and navigate.

4. Clear the data of the navigation software, or replace it with other navigation software for observation. 5. If the fault persists, restore the backup data to factory settings.

GPS is not a strong signal in every place, such as villages, mountains, these places have a bad signal.

Summary. Hello dear! Navigation is always showing the location signal is weak, and the following situations are common:

1. Mobile phone positioning relies on satellite microwave transmission location information, microwave is a very easily blocked substance, so the vehicle driving in tunnels, underground parking lots or sheltered places will affect the signal transmission of mobile phone positioning;

2. According to the transmission characteristics of satellite position signals, high-voltage wires, signal transmission towers and other devices will interfere with satellite signals, so that the mobile phone positioning signal is weak;

3. The weak positioning signal of the mobile phone may also be caused by itself, such as the car glass is covered with a metal film, and the metal particles of the metal film will isolate the electronic signal;

4. The size of the mobile phone memory will also affect the strength of the positioning signal, and the weak positioning of the mobile phone may be caused by the small memory of the mobile phone.

Why does the navigation always show the weak signal of the location?

Hello dear! Navigation always shows that the location signal is weak, and there are the following common situations: 1. Mobile phone positioning relies on the microwave transmission of satellite location information, microwave is a very easily blocked substance, so the vehicle driving in the tunnel, underground parking lot or obstructed place, will affect the signal transmission of mobile phone positioning; 2. According to the transmission characteristics of satellite position signals, high-voltage wires, signal transmission towers and other devices will interfere with satellite signals, so that the mobile phone positioning signal is weak; 3. The weak positioning signal of the mobile phone may also be caused by itself, such as the car glass is covered with a metal film, and the metal particles of the metal film will isolate the electronic signal; 4. The size of the mobile phone memory will also affect the strength of the positioning signal, and the weak positioning of the mobile phone may be caused by the small memory of the mobile phone.

It can be adjusted in the following ways: 1. Confirm whether to turn on the location service of the mobile phone, select "satellite, WLAN and mobile network positioning mode" as much as possible, and turn on the wireless network and Bluetooth switches; 2. The positioning signal of the mobile phone is weak, it is recommended to locate and restart the navigation in a place with a strong network signal and an open and unobstructed surrounding environment to ensure the normal reception of the satellite signal; 3. When using mobile phone navigation, it is necessary to upgrade the navigation software and map information in time to obtain the latest road conditions, or use other navigation software; 4. Some mobile phone cases, especially metal protective cases, will easily affect the signal strength of satellite positioning, so it is recommended to remove the metal phone case when navigating.

1. Confirm whether you are wearing a protective case

Due to the electroplating, metal, magnetic and other protective shells have certain shielding and anti-interference characteristics, it will lead to poor or unstable signal of the mobile phone. Since you're not sure if your case contains these materials, it's a good idea to remove the case and see if it will return to normal.

2. GPS switch and application settings

If the GPS switch is not enabled, it will affect the positioning accuracy of the mobile phone, so it is recommended that you turn on the GPS switch and set the app location permission to allow.

GPS switch: Set > Permissions & Privacy > Location Information > Turn on Location Services Switch, Turn on Wi-Fi and Bluetooth Scanning.

3. Application software

This is true for all navigation software:

1. It is recommended to turn off and on the GPS switch and restart the phone to see if it can return to normal;

2. If there are devices in the car that may interfere with the signal source, such as the dash cam, which will affect the GPS signal, it is recommended to try to turn off these devices to see if they can return to normal;

3. The system version update will optimize the mobile phone to a certain extent, it is recommended to update the mobile phone to the latest system version first to see if it can solve the problem;

This is true for some navigation software:

If only some of the navigation software is abnormal, it may be caused by the compatibility of the navigation software with the mobile phone, it is recommended to update the navigation software to the latest version, or replace it with other navigation software.

4. None of the above methods can solve your problem

Please bring the purchase invoice, warranty card and mobile phone to the nearest OPPO customer service center for testing and processing by professional engineers. Before you go, please back up and migrate your mobile phone data in advance (the data of the safe and QQ WeChat need to be backed up and migrated separately), and before going to the service center, please contact the staff of the service center in advance to confirm after-sales matters.
