What should I do if the signal deteriorates after the Vivo Y66 system is upgraded?

It is recommended that you try the following methods:

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.

You can try changing places to see if there is a change in the cell phone signal.

2. Re-register the network.

You can restart your phone to let it re-register for 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.

Fourth, the operator's network problems.

If the signal of the mobile phone suddenly deteriorates during a certain period of time, it may be a problem with the operator's network.

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 shell.

The metal case will have a certain impact on the phone signal.

It is recommended to remove the metal protective case, replace the factory mobile phone protective case to protect the mobile phone, and then observe and use it.

There is no signal on mobile phones because the signal will be affected by various factors such as terrain, landform, and tall 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.

The reasons for the unstable connection signal of the mobile phone are:

1. The router signal is unstable. Restore the router to factory settings, and then reset the broadband account password again.

2. If there is a problem with the mobile phone network setting, first detect the mobile phone network signal 3, and the mobile phone network setting is wrong.

4. There may be a problem with getting the IP automatically, you can try to set it manually.

5. In the case of connection, generally press the SSID name, there will be a menu to select "Modify Network Configuration", check "Show Advanced Options": 6, IP Setting: Select Static

Go and see if it's a card problem or a system problem.

The method of strengthening the signal of the mobile phone is as follows, the following three steps will immediately solve the problem of no signal on the mobile phone, so that the mobile phone is full:

1. Place an outdoor antenna.

As long as the antenna is placed in a place with a stable signal (not necessarily full), such as placing the outdoor antenna on the roof of an outdoor air conditioner, or by a window, balcony, etc.

2. Connect the antenna.

Connect the wired outdoor antenna to the outdoor interface of the host, and connect the indoor antenna without wired to the indoor interface of the host. If there is an outdoor and indoor interface on the host, be careful not to reverse it!

3. Connect the power supply.

Place the main unit in the room where the signal needs to be covered, either on the ground or on the table. Note: The host should be kept at a certain distance from the outdoor antenna, preferably above the meter, if there is a wall block, the meter can also be.

Then, connect the power supply and power it on.

Once powered on, wait a minute or two.

At this point, the mobile phone signal amplifier starts to work, you can take out the mobile phone to see how the signal is.

1. There is no signal or the signal is relatively poor, mainly because the signal will be affected by various factors such as terrain, landform, and high-rise buildings in the process of propagation, such as the current location is in a relatively closed place, and the signal may be affected.

2. If the mobile phone signal of other China Unicom users is normal, the following methods can be used to troubleshoot:

Method 1] Turn on airplane mode, then turn off or restart your phone and try again.

Method 2] Test of changing the phone card to change the mobile phone card to the mobile phone of a family member or friend and try again.

The GPS of mobile phones has poor module reception ability, and if the brands are different, there is a big difference.

GPS is affected by weather, high-rise buildings, etc., if it is a mobile phone, it is recommended to turn on the "GPS Enhanced Assist" and "Network Positioning" functions to assist positioning in the case of poor GPS signal.

What version of your phone appears after updating to it? It is recommended to try the following methods:

1. Restart the phone and let the phone re-register the network;

2. Take out the SIM card and reinsert it or replace the SIM card to eliminate the SIM card failure;

3. Use after changing the network environment and time period, and you can also compare other mobile phones (using the same network) to see if this phenomenon exists, if it also exists, it may be caused by the poor signal coverage of your local network operator. For example, some tall buildings, basements, parking lots, remote mountainous areas, etc. can affect the mobile phone signal.

It is recommended that you update your phone to the latest version, which can improve the compatibility and stability of the system, and can also fix some known bugs, and sometimes accompany the push of some new features.
