In February of this year, Buffett said that he finally gave up using the Samsung U320 clamshell feature phone, which was worth only $ 20 for many years, and replaced it with an iPhone 11. The 89-year-old began to learn to use it, and temporarily regarded it as a phone, unlike others. Many functions of iPhone are generally used.
In an interview with Yahoo! Finance recently, he revealed that Tim Cook spent hours teaching him to use the iPhone 11, and he laughed and said that after using the instructions, his ability to use the iPhone improved to the level of a 2-year-old.
However, during his visit, Buffett didn't bring his iPhone to "attend" at the same time. He explained that he was afraid of disturbing the call (it seems that he didn't know how to use the Do Not Disturb function).
