Although mobile phones are becoming more and more intelligent, the phone is still the most core function. Many phones support basic call noise cancellation, which is achieved by collecting background noise through dual microphones. On the iPhone, the feature Chinese called phone noise cancellation, which Apple describes as reducing ambient noise in the phone when the user puts the handset to their ear.
However, iPhone 13 users found that the phone does not have this feature option, and after communicating with Apple Support, it was confirmed that this is not a BUG, but permanently removed. As for why Apple suddenly removed the feature, the reason is unknown, but the previous iPhone models have this setting item, which is located under the accessibility column.
The strange thing is that the media AI called Apple customer service on Saturday local time, and the other party's statement was still that this was a system BUG.
