What to do if the phone has an electric current sound when you are on a call

If your phone has poor call quality, it is recommended that you:

1.Trying to move the location may be caused by a poor signal at the location.

3.Update your phone's system version: Settings - About Phone (About Device) - Manual Update Automatic Update (Software Update System Update - Update). Note: Please back up the data in your device before upgrading.

4.Replace it with a different SIM card.

Try. 5.If the problem persists, it is recommended that you bring the purchase invoice, repair card and mobile phone to the local Samsung service center for professional engineers to help you test.

The solution to the reason why the mobile phone has an electric current sound:

1. The current sound from the other party's mobile phone call:

The other party's mobile phone MIC assembly is not in place, and it is caused by contact with the metal of the face shell. Contact between MIC and metal will cause current sound, and it is necessary to isolate the MIC and metal with insulating glue or foam. A standby companion can solve this problem.

2. The current sound of your own mobile phone:

The anti-interference force of the REC of your mobile phone is poor, usually the quality of the REN is not good, and the call is caused by the interference of the antenna, you can replace the REC with good interference, and you can solve the current sound. Or wrap the conductive imitation Pei Yi wire of REC with conductive cloth to increase the anti-interferon power of REC. The problem of the mobile phone motherboard, the motherboard can add electronic devices to filter out the interference of the handset.

This issue can also be fixed. Regardless of which mobile phone the current sound is, it can be verified by the elimination method.

Probability of mobile phone **:

Nowadays, mobile phones are basically lithium batteries, and the probability of finding danger is 1 in 100 million to 3 in 100 million. Although the probability of accidents is extremely small, 80% of accidents occur during charging. This is because the voltage is higher when the phone is charging than when it is standby, and if you perform other operations at the same time, such as making a mistake, the voltage will be many times higher than usual.

In this case, the use of inferior chargers, aging or moisture of mobile phone electronic components may cause leakage, and the mains power in the socket is connected, and then the current passes through the human body, once the current passing through the human body in a short period of time is too large, it may lead to death. If you use a battery produced by a regular manufacturer, the probability of occurrence is very small. <>

The solution to the sound of the current on the phone.

1. Open the security center of the phone, clean up the cache junk of the phone, and then turn it off and restart;

2. Affected by the magnetic field and sound waves of the environment, remove the electrical appliances with magnetic fields, such as mobile phones and fans;

3. Turn off the phone, then press and hold the power button and the volume up button at the same time, let go after vibrating, and then select Wipe Data Factory Reset to restore the factory settings of the phone to erase all data;

4. It is recommended to go to the local authorized service experience center and ask the engineer to test it.

The reasons for the sound of electric current are:

1. If the surrounding magnetic field radiation is large or the signal is not good, you only need to dial ** in another place.

2. There is a problem with the transmitter of the mobile phone, and the maintenance personnel need to change the transmitter.

3. The audio control IC of the motherboard of the mobile phone is faulty.

If the MIC of the other party's mobile phone is not in place, it will lead to the current sound of the call, at this time, Kuan Ranxiang can let the other party isolate the MIC and the metal with insulating glue or foam.
