Why is there a lot of noise when talking on my phone?

There are three possibilities for this situation: 1. Whether it is a signal problem, try it in a different position to see if there is such a phenomenon. 2. It may also be caused by some software incompatibility after you upgrade the software, you can take it to the service point for re-upgrade, or you uninstall it and reinstall it, 3 If the above have been tried, it is a hardware problem with the mobile phone, that is, the mobile phone earpiece has a noise, which needs to be replaced or repaired, and can be repaired before the warranty period.

There are two sides to the problem here. If this has always been the case, I suggest you change the earpiece, because it is a problem with the handset of the mobile phone. If it's just occasional, then don't worry too much, it may be a problem with a weak mobile phone signal.

If there is noise in the call on vivo mobile phone, it can be solved by the following methods:

1. Hang up ** and redial to see if it still exists;

2. Restart your phone to see if it is restored;

3. Try changing the network environment;

4. Enter the mobile phone settings - system upgrade - detect and update the system;

If the fault persists, please bring the purchase invoice, warranty card and mobile phone to the nearest vivo after-sales service center for testing and processing. The address of vivo after-sales service center can be entered into vivo official website - service network query - select the province and city where it is located.

It may be that there is a problem with the microphone inside, so don't you go to the after-sales service to take a look.

If you hear a noise during a call on your mobile phone, you can use the following methods to troubleshoot the operation:

1. Check whether there is a problem with your own equipment.

If you're only experiencing this issue when you're on a call to a specific person, it's possible that the device you're talking to is malfunctioning, not your own.

2. Check whether the device signal is normal.

If the device signal is not normal, it will affect the call quality.

3. Make sure the earpiece or speaker.

The sound outlet is not occluded.

Please ensure that the device uses a matching protective case and protective case to avoid the position of the sound outlet of the earpiece or speaker being blocked.

4. Try after restoring all settings.

For specific methods and precautions, please click Reset All Settings.

5. If the call on your device is still abnormal, please back up your data in advance (third-party apps such as QQ and WeChat need to be backed up separately) and bring your purchase voucher to a nearby Huawei Customer Service Center for more help.

Make an appointment for service. Boarding service.

If you have noise when using OPPO mobile phone to make calls, you can try the following methods:

1. Please check whether the microphone is blocked by foreign objects, if so, you can clean it up and try again;

2. Due to the electroplating, metal, magnetic and other protective shells have certain shielding and anti-interference characteristics, which will lead to poor or unstable signal on the mobile phone.

3. If the mobile phone is used in the office, residence, train, underground garage and other places, there is a call sound problem, and the signal on the mobile phone is displayed as less than three bars, it is recommended that you try the following methods:

1) Make sure that the system version of your phone is updated to the latest version, and upgrade the system version to the latest in Settings > > Software Update.

2) It is recommended to use the original protective case of the mobile phone, do not use metal or gold-plated protective case.

3) If you are in a special area (bus station, high-speed rail station, basement, elevator), the mobile phone signal will be affected, it is recommended that you leave such an area for a distance and try again.

4) If the SIM card hardware is damaged, it can also cause the signal to be abnormal, it is recommended that you swap the SIM card to other mobile phones for comparison.

5) If there are problems with other mobile phones in the same area, it can be determined that it is a network problem with the operator, and it is recommended that you report the problem to the operator for processing.

If none of the above methods can solve your problem, it is recommended that you bring your purchase voucher to the OPPO official service center for testing and processing by professional engineers.
