iPhone X, the phone's screen-to-body ratio has been greatly improved, and the aesthetics have also been greatly improved, but this phone has made mobile operators around the world feel "angry" because there is no place to display carrier information in the space at the top of the screen. In fact, the carrier information has not been completely removed, and the user needs to swipe down the screen at the location where the time is displayed to view the operator information.

According to a number of foreign media reports, in the past iPhone or other Android mobile phones, various information will be displayed in the status bar at the top of the phone, including system time, battery level, and operator information.

It's important for carriers to keep their brand on top of their phones. According to foreign media reports, although operators play a very important role in the U.S. smartphone market, Apple's position is stronger, Apple does not allow operators to implant official software in the iPhones they sell, so that the only way for operators to improve the presence of mobile phones is the operator information at the top status bar.

In the iPhone X, Apple has adopted a narrow bezel design, and the screen-to-body ratio has been greatly improved compared to the previous iPhone. However, at the top of the screen, Apple arranges some indispensable components such as 3D recognition sensors, speakers, cameras, etc., through an area similar to the "forehead".

This design results in a reduction in screen space in the top row. Naturally, this will not be able to display all the status bar information in the past. Apple executives demonstrated on Tuesday that the iPhone X will only display a handful of information at the very top: the time, mobile network signal, Wi-Fi signal and battery level.
