How to solve the signal difference of vivo X9?

The reason why there is no signal on vivo mobile phones is that the signal will be affected by various factors such as terrain, landform, and high-rise buildings during the propagation process, and if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

1.Turn the phone back on and off and try again;

2.Swap the SIM card to a family member's or friend's phone and try again;

3.Check to see if other Unicom users around you have a signal;

If there is no signal, you can contact human customer service for feedback.

1. The use of data network speed is slow and the signal is poor.

Restart your phone; Try to replace the ** card;

Go to mobile phone settings - mobile network - access point - change access point to try;

Replace the stable network environment or change the time period (avoid being in a closed room, surrounded by tall buildings, poor network signal coverage, etc.), or connect to wifi if conditions permit;

Go to iButler - Traffic Monitoring - Network Management to see if the software uses the data network.

2. Use the wifi network with slow network speed and poor signal.

If it is your own WiFi, you can restart the router to try; If it is a public WiFi, you can try to change it to another WiFi;

The number of users around, different time periods, and distance from the wifi transmitter source will also have an impact on the wifi network speed, you can try to change the time period.

vivo X9 Signal Enhancement Design].

Signal+ Signal Enhancement and High-Speed Rail Mode.

In terms of improving the user's signal receiving experience, vivoX9 has added Signal+ signal enhancement and high-speed rail mode. Specifically, by optimizing the antenna gain capability and sensitivity in weak signal environments, the voice and data communication capabilities of mobile phones in weak signals are greatly improved, and they can quickly respond to the environment and quickly switch back to normal networks, such as when entering and exiting elevators and basements. It also supports high-speed rail mode, which intelligently matches the frequency band and adjusts the mobile phone signal transmission to improve the switching ability of the base station and reduce the mobile phone network drop rate in high-speed driving.

Now we use mobile phones in the scene will be in an environment like an elevator or basement at a high frequency, vivoX9's signal enhancement design can make the mobile phone's signal reception sensitivity and responsiveness higher.

1. Change the network environment: the mobile phone is in some tall buildings, basements, parking lots, etc., which will affect the signal; If you are in a closed place (e.g., an elevator) or in a remote area, it is easier to disconnect your phone from the outside world.

2. Re-register the network: You can restart the mobile phone to let the mobile phone re-register the network.

3. Determine whether the SIM card is valid: If the SIM card is not installed properly, or the SIM card is damaged, the signal will inevitably be affected. You can remove the SIM card and reinstall it, or try a different SIM card.

4. Operator network problems: If the signal of the mobile phone suddenly deteriorates within a certain period of time, it may be a network problem of the operator. It is recommended to compare mobile phones with the same carrier SIM card in the same environment to see if there is the same situation, and you can try it at another time period.

5. Whether to use a metal protective case: The metal protective case will have a certain impact on the mobile phone signal. It is recommended to remove the metal case, replace the factory mobile phone case to protect the phone, and then observe and use it.

If you have dismantled your mobile phone, it is recommended to go to the vivo after-sales service center to deal with it. The address of vivo after-sales service center can be queried by entering the mobile phone settings - more settings - service outlets and selecting the province and city where it is located.

Note: You can call ** first to confirm the after-sales working hours and plan the itinerary reasonably.
