Why is the vivox9s network I use so poor

If the network abnormality occurs on vivo X9s, you can try to solve it in the following ways:

If there is an abnormality in the use of the WiFi network:

1. When connecting to the wifi network, you need to enter the correct wifi password, and use it in a place where the wifi network coverage signal is good.

2. Whether other devices can be connected to the currently used WiFi network, replaced with other WiFi for use or connected to a personal hotspot.

3. Enter the mobile phone settings - WLAN - forget the currently connected WiFi network, re-enter the password to connect again, or try to find WLAN in Settings - More Settings - Application - All - Storage - Clear Data and then connect to the WiFi network to use.

4. If the above phenomenon still occurs, you can try to restore the wifi router to factory settings, reset the wifi nickname and password to connect and use again, and then enter the mobile phone settings - more settings - restore factory settings - restore all settings and then connect to wifi.

If there is an abnormality in the use of the data network:

1. Call the operator** and check with the relevant staff whether the SIM card is in arrears.

2. It is recommended to insert the mobile SIM card into other mobile phones to use the data network to check whether the local mobile network is unstable.

3. It is recommended to insert other operator cards (Unicom cards or telecom cards) into the mobile phone to use the data network to see, if the SIM card of other operators can use the data network normally, it may be that the local mobile signal is unstable, if other SIM cards will also appear this phenomenon, it is recommended to enter the settings - mobile network - access point - reset to the default settings, and then restart the mobile phone to observe and use it.

Do you need these stupid? Issue.

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.

If you are connected to a WiFi network, it may be because you are connected to a large number of WiFi connections, or you may be too far away from the router, it is recommended that you try the following methods to solve the problem:

1. Stay close to the router and connect to the WiFi;

2. Restart the router and connect to the WiFi immediately, or restore the router to factory settings to re-encrypt the WiFi;

3. Try to change the wifi connection in other places.

If you are connected to a data network, it may be because the environment you are in is relatively closed, we recommend that you try the following methods:

1. Change to a location with a better network environment or enter the mobile phone settings - mobile network dual SIM and mobile network - access point - change the access point to try (avoid being in a closed room, surrounded by tall buildings, poor network signal coverage and other environments);

2. Switch to 4G network use;

4. Compare and observe the time period and the use of different software data networks.

1. Automatic upgrade of the system when the branch is turned off: When there is a major version upgrade, many old vivo models cannot drag the new system on the hardware, and the mobile phone will become stuck. Therefore, in general, try to turn off the automatic upgrade of the system as much as possible, so that you can alleviate the situation of mobile phone jamming.

2. Turn off the background refresh function of the software: When the ** software, the background refresh function is automatically turned on, which will consume the running space of the mobile phone, so it is recommended to close the software that usually does not need to receive messages in time, so that it will only run when you open the software, which can also increase the smoothness of the mobile phone.

3. Cache cleaning: Of course, because there are more and more applications in the mobile phone, there must be more and more caches, so we must clean the cache for each application, so that the situation of mobile phone jamming can be solved.

4. Folder cleaning: There are so many folders in the mobile phone, so you can clean up the folder appropriately, so that you can solve the situation that the mobile phone is stuck. These can be cleaned up, cache is cache garbage, which can be cleaned up; data is the data, which can be a folder except WeChat; DCIM is a photo album, it is better not to clean it, but you can clean the cache** and lock screen wallpaper in it; temp is the browser cache car, and the privacy of the usual cache can be cleaned up here.

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;

It is recommended that you try the following methods to solve the problem first:

1. Shut down and restart;

2. Try reinstalling the SIM card or replacing it with another SIM card;

3. Try to change the network environment and time period, and at the same time, you can compare other mobile phones (using the same network) to see if there is such a phenomenon.
