For Apple, signals seem to be an insurmountable hurdle.

As early as the 2010 iPhone 4, a "antenna gate" had already emerged. On June 24th of that year, the world-renowned iPhone 4 was officially released, but a few hours later, American netizens posted on forums claiming that the iPhone 4's proud wireframe antenna design had fatal flaws. When users tightly grip the iPhone 4 with their hands, its mobile network signal will completely decay to the level of being unable to make calls within minutes, which is known as the "Grip of Death".

But Apple still maintains its own arrogance, which has been present throughout Apple's history. A loyal user sent an email to Steve Jobs, saying, "I really like this phone, but as soon as I hold onto the metal gap on both sides of the phone, the signal disappears. Can you solve this problem?"

However, Steve Jobs refused to acknowledge this issue and even told users, "It's best to change the way you get your phone." Even at the press conference on the "antenna gate," he avoided apologizing and simply said, "You know, we're not perfect, and phones are not perfect either. But we want all users to be satisfied. If you don't know this, then you're not familiar enough with Apple."

In the end, Apple did not recall the problematic iPhone 4, but instead gave away a free Bumper phone case, which also burned down phone manufacturers such as Nokia, Motorola, and BlackBerry, stating that other smartphones would also have such problems, and was even used as a model for crisis public relations in the future.

But now the iPhone signal is still the most complained about point by users. Everyone has a question more or less in their heart. Why can't Apple, which has produced the world's most powerful mobile chip, fix the signal and the humble baseband chip?

The first generation of iPhone in 2007 was not as mature as it is today. Apple, which had never made a phone before, used its existing supply chain of iPod and Mac to "piece together" a hardware device: the processor, NAND, an
