With the development of smart phones, the functions that users can experience are becoming more and more abundant.
But as a mobile phone, the call function is the most basic, but also one of the most needed functions for users.

In the previous article, Xiaoguo shared the problem of the lack of noise cancellation function of the iPhone 13 series for everyone.
Call noise cancellation is a function that has been equipped with iPhones for generations since iPhone 5, which can effectively reduce background noise during calls.
We can find the "Phone Noise Cancellation" function through "Settings" - "Accessibility" - "Audio/Visual" and select to turn it on or off.
As early as last October, some users reported that they could not find the call noise cancellation function in the iPhone 13.
The official description of this feature still exists in the iPhone manual on Apple's official website, so most users, including Xiaoguo, think it is a bug.
This issue has recently received the latest news.
According to Apple's latest reply, this feature may be permanently absent from the iPhone 13 series models.
According to foreign media 9to5Mac, an Apple user Steve shared his conversation with Apple's support team.
Steve said he contacted a senior apple consultant a few months ago and got an answer that needed to wait for an update to address the missing call noise cancellation feature.
Now, Apple has updated its feedback on the issue, and Apple says the issue is not a bug and will not be fixed.
When Steve asked the Apple support team again whether the iPhone 13 series did not support call noise cancellation, the Apple support team replied, "Yes, no."
In this way, the lack of call noise cancellation on the iPhone 13 is not a bug, but a deliberate effort by Apple.
In fact, in the cutting function of this piece, Apple can be said to be familiar with it.
From cutting off the headphone interface, to the current external rumors of the SIM physical card slot and charging interface that will be cancelled in the future, Apple's determination to do an integrated iPhone can be seen.
However, when Apple announces the cancellation of one function, it will generally replace it with another function.
For example, cancel the Touch ID fingerprint recognition function and replace it with Face ID facial recognition.
3D Touch was eliminated and replaced with haptic Touch.
In the future, Apple may also introduce eSIM card slots and fully adopt wireless charging to replace traditional SIM physical card slots and traditional charging interfaces.
However, there are some features that Apple canceled, and users still hope to be able to return, such as Touch ID fingerprint recognition and 3D Touch.
Xiaoguo and most users also hope that the call noise reduction function can return.
After all, mobile phone calls are just a feature for most users.
