Why do you think the function of mobile phone is becoming less and less important?

It really doesn't matter. The mobile phone belongs to the mobile terminal and can be held in your hand. Until now, mobile phones have become a very important tool in people's lives, and their functions are diversified. In the past, the main function of the mobile phone was the call function. With the development of mobile phones, there are more and more chat software on mobile phones. People prefer to communicate on these applications rather than make phone calls, and sometimes they feel anxious when they hear the ringtone of their mobile phone or phone. The few call records on mobile phones are usually takeout, express delivery or promotion.
