The Apple 7 starts the call with good effect, what should I do if there is noise in the call after u

1. In "Settings" - "General" - "Accessibility".

2. Turn on "** noise elimination".

What to do if the iPhone call is quiet:

First of all, what we need to do is troubleshooting:

Step 1: Judge.

First of all, please make sure that you are listening to someone else's voice or someone else is listening to your voice is low, and then rule out whether it is because the call volume is set to be low.

Step 2: You listen to other people's voices to investigate the cause of small problems.

There is a problem with someone else's microphone (or a problem with his call volume setting); Your handset is blocked, (e.g. a protective film is attached to the handset); The signal is not good; If the problem with your mobile phone settings is serious, it is necessary to find after-sales service, such as 18C11, Block T2, Xihuan Plaza, No. 1 Xizhimenwai Street, Xicheng District, Beijing

It's a problem with the phone's settings, a hardware problem with the phone.

If the call is noisy, you can turn off mono audio and turn on ** noise cancellation in Settings - General - Accessibility - Accessibility. This reduces noise.

If there is noise when using the hearing aid device, you can turn on Settings - Accessibility - Hearing Aid Devices - Turn on the hearing aid mode, so that the audio quality can be improved.

iPhone is a series of smartphones developed by Apple, which is equipped with the iOS mobile phone operating system developed by Apple. The first iPhone was released by the company's CEO Steve Jobs on January 9, 2007, and officially went on sale on June 29 of the same year.

In 2004, Steve Jobs, Apple's chairman, assembled a team of more than 1,000 in-house employees to develop the iPhone, and began a highly classified project called "Project Purple," including Jonathan Ive, the designer behind the iPhone.

At the time, Apple's CEO, Steve Jobs, shifted from tablets with a focus such as the iPad to a mobile phone.

Apple secretly partnered with AT&T to create some hardware and software devices—the then Cingular wireless network—AT&T and gave Apple a lot of investment and freedom, spending about $150,000,000 over 30 months. In exchange, Apple guaranteed that the iPhone in the United States** would be sold exclusively to AT&T for four years.

Apple's rejection of the "design committee" approach and refusal to produce the Motorola Rokr E1 was a major factor in the unsuccessful cooperation with Motorola.

Instead, Cingular gave Apple the freedom to develop the hardware and software inside the iPhone, and even paid Apple a small percentage of their monthly service revenue (up to the iPhone 3G) in exchange for their exclusivity in the U.S. for four years ending in 2011.

iPhone is usually caused by the phone not turning on the phone's noise cancellation function. Here's how to fix it:

1. You can first enter the phone's settings - general - auxiliary function - **noise cancellation - on; Generally, it can be returned to normal after turning it on.

2. If the noise cancellation function is turned on, the mobile phone still has a lot of noise, which may be caused by the failure of the mobile phone's transmitter or the short circuit or leakage, and you need to contact Apple's official after-sales service for maintenance to solve it.

If your iPhone calls are quiet, we can turn it up in the settings.

Turn on your phone and go to the Settings app.

Find "General".

Select Accessibility.

Swipe the page to the bottom and see the "Noise Cancellation" switch turned on. This method is relatively general, if you find that there is a problem, you can try this method first.

There is also a relatively simple way, when talking to others, you feel that the sound is relatively quiet, press and hold the volume button on the left side of the phone, and increase it.

If you really feel that the sound is low, you can go to the Apple retail store to test it for free to see if it is a hardware problem. If it's a hardware problem, it's time to take it for repair.

Method: 1. To adjust the volume of the call sound, please feel free to open a**.

2. Press Apple's volume plus or minus buttons again to adjust the sound volume to a suitable level, and the volume adjustment icon will also appear on the screen.

Note: 1. If the call sound is still very small after following the above method, there may be a hardware problem. First of all, you can try to change a different ** card to try it and see if it can solve the problem of low sound.

If the sound returns to normal after changing the card, it means that it is a problem with the original ** card.

2. If there is still a problem after changing the card, you can also try to restore all the settings of the system at this time. It can be operated in [Settings - General - Restore].

3. If the problem still cannot be solved after resetting the settings, it may be a hardware failure of the Apple mobile phone, at this time, please go to Apple after-sales service for detection and processing.
