What s going on with the phone suddenly getting so weak?

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.

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.

Feedback, we will check and deal with it as soon as possible.

Whether it continues to weaken, or is it strong and weak, or it is better to change places. There are many reasons for signal weakness, the most important ones are 3, one is the problem of signal coverage, this is no way. The second is that the mobile phone antenna is loose, as for your mobile phone model, you can know where the antenna is, you can get it yourself, or you can go to the repair shop.

There is a virus in the three machines.,Grid machine or flash machine.。

Either there is a nearby building that shields or blocks the signal, or the mobile phone is stuck when searching for the signal. Reboot is recommended.

The sudden poor cell phone signal could be due to these reasonsElectromagnetic interference, regional disconnection, weather conditions, **large, base station switching.

1. Electromagnetic interference

Mobile phone signals are through electromagnetic waves.

When the interference of certain electromagnetic waves exceeds a certain level, the mobile phone will have no signal or drop call.

2. The area is disconnected

When the partners cross one service cell to another during the call, the voice channel will be switched, and if the handover fails, the call may be interrupted.

3. Weather conditions

Weather such as strong winds and thunderstorms will also affect the transmission of mobile phone signals.

4. Large, base station switching

The saturation of call volume on the carrier's network can also cause a poor cell phone signal. Due to the capacity constraints of each base station, network speeds can sometimes occur in densely populated places.

1.Please check the SIM card.

1) If your mobile phone card is manually cut, there may be signal problems due to non-standard shape and poor contact, it is recommended that you bring your personal ID card to the operator's business hall to apply for a standard mobile phone card.

2) Dirty or oxidized SIM cards will also lead to poor contact, so it is recommended that you keep the SIM card clean.

2.Please avoid interference from metal or magnetic materials.

If your mobile phone uses a special metal protective case, or you are in an elevator, car and other environments, it is recommended that you remove the mobile phone protective case or leave the elevator, car and other environments, metal and magnetic materials are easy to interfere with the signal, resulting in poor mobile phone signal.

3.Please rule out network causes.

1) Make sure you are in a good environment.

In some more enclosed indoor environments, such as houses with dense spacing between buildings, the mobile phone signal may be blocked, resulting in poor signal.

Carriers' network coverage varies depending on the region, and some areas may have insufficient coverage capacity, resulting in poor mobile phone signals.

If your mobile phone has a poor signal in a specific area, or if a nearby friend's mobile phone using the same carrier** card also has a poor signal, it may be caused by the poor network quality in your location, and you can return to normal after changing to another place.

2) Please restart your phone or switch on airplane mode.

Special configurations of some networks may cause your mobile phone signal to be poor, which can be restored after restarting your phone or turning on airplane mode.

3) Please reset the APN

Open Settings, enter APN in the search bar at the top, tap Access Point Name (APN) to jump to the mobile data settings interface, tap Access Point Name (APN) again, then tap Three Dots or Four Dots in the upper right corner, and select Reset to Default Settings to try.

4) Please reset the network settings.

4.Please update your phone system to the latest version.

If your phone still has poor signal, contact Huawei Consumer Service** (950800) for further assistance, or back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately), bring your proof of purchase, and go to a Huawei Customer Service Center near you.

Causes of poor cell phone signal:

The network of the surrounding environment is relatively poor, which will lead to the signal being in a non-service state;

Some reasons of the system itself, resulting in the mobile phone cannot be connected to the network;

Problems with the SIM card of the mobile phone;

Solution: Turn on airplane mode and then turn off airplane mode, and the system will search for network signals again. Open Settings on your phone, then turn on the button to the right of the airplane mode option, wait a few seconds and then turn it off;

Fix the no-service issue by resetting the network settings, reverting to the default factory settings, or by restarting the phone;

You can turn on the general software update from your phone's settings to try to update the system.

If it's not where you are, the network is getting worse, it's likely that there is a problem with the phone, and the specific problem is recommended to go to the mobile phone store for repair, because I told you, you still won't repair it!

The phone signal becomes very poor, it may be a problem with your battery, and it will also affect the signal of the phone.

The mobile phone signal is not good 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:

Turn the phone back on and off and try again;

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

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

If you can't solve the signal problem, you can contact the customer service of Unicom where the number belongs to verify the specific reason.

1. If there is no signal or the signal is relatively poor in your location, it may be due to other objective conditions. Because the signal will be affected by various factors such as topography, landform, and tall buildings during propagation, if you are in a relatively closed place, the signal will be affected. Here's how to deal with it:

Turn the phone back on and off and try again;

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

Check whether the signals of other Unicom users around you are normal.

2. If it still cannot be used normally after self-service troubleshooting, it is recommended that you contact the local manual customer service for verification and processing.

I guess the signal transmitted by the satellite is weak.

Landlord: This must have been broken by you.

This is taken to the mobile phone store and brushed down the system.

Reason 1: Because the signal is unstable in the place where the mobile phone is located, the network is unstable. The strength of the signal received by the mobile phone is determined by the signal strength sent by the mobile phone base station and the distance between the mobile phone and the nearest base station.

Solution: The signal transmission strength of the base station and the bent mode receiving sensitivity of the mobile phone wireless network card cannot be changed, and the strength of the received signal of the mobile phone can only be changed by moving the mobile phone to a place relatively close to the base station and the signal is good.

Reason 2: Bad signal caused by external interference. Since the mobile phone receives the signal, it works by the propagation of electromagnetic waves.

Therefore, the interference of electromagnetic waves will have a negative impact on mobile phones. When the interference of certain electromagnetic waves in the air exceeds a certain level, the signal-to-noise ratio of the mobile phone is reduced below the standard value, and the mobile phone will appear none.
