The 4g signal of 5g is getting worse and worse.

If you use a Huawei mobile phone, when there are more or less signal grids in the status bar of the mobile phone, it is suggested to take the following measures to try to solve the problem:

1. Please avoid using magnetic/metal protective shell, magnetic bracket or magnetic sucker.

Metal and magnetic materials easily interfere with signals, resulting in poor cell phone signals.

2. Please try to change a mobile phone card.

It is recommended that you install other mobile phone cards in your mobile phone. If the signal of other mobile phone cards is normal, there may be something wrong with your mobile phone card. I suggest you go to the operator's business hall to replace a new mobile phone card.

3. Please try to move the current position.

(1) In some closed indoor environments, such as densely spaced buildings, the cell phone signal may be blocked, resulting in poor signal. You can go outside and see if the cell phone signal can return to normal.

(2) Operators' network coverage varies according to different regions, and urban areas basically meet the coverage, but some remote areas may have insufficient coverage capacity, which will lead to poor cell phone signal.

You can judge whether the current regional network coverage is poor by whether the cell phone signal is poor in the same area or whether the cell phone periphery of the same operator's calling card is poor.

4. Check whether the APN setting is correct.

Incorrect APN settings will affect the normal use of the network.

Method 1:

A. click settings;

B. Enter "APN" in the top search bar, and click the name of the access point (APN) to enter the mobile data page;

C. Click the name of the access point (APN) to enter the APN page;

D. Open the three point buttons in the upper right corner;

E. click reset to default settings.

Method 2:

If your mobile phone is above EMUI 10.0, above Magic UI 3.0, or above HarmonyOS system 2.0, you can also follow the following steps:

A. click settings;

B, click on the mobile network, and then click on the mobile data;

C. Click the name of the access point (APN) on the mobile data page to enter the APN page;

D. Open the three point buttons in the upper right corner;

E. click reset to default settings.

Warm reminder:

If your mobile phone is the system of EMUI 8. x，EMUI 9。 X or magic UI 2. X, you can follow these steps:

Settings > wireless and network > mobile network > access point name (APN) >; Open the three-point button in the upper right corner > reset to default settings.

5. Please try to restore the network settings.

You can go to Settings, search to restore network settings, and then click Restore Network Settings.

Tips: Restoring the network settings will delete the WLAN and Bluetooth connection records, and you need to enter the screen lock password for verification.

If the above investigation can't solve your problem, I suggest you contact Huawei's customer service hotline (950800) for more help, or back up the data in advance (WeChat /QQ and other applications need to be backed up separately), and bring relevant purchase vouchers to the nearby Huawei customer service center for testing.
