How a smartphone works: disassemble it into parts
Today, almost every person has a smartphone. But few have seen how it works inside. Popular mechanics took care of this: so that you do not have to disassemble your own device (and buy a new one after unsuccessful attempts to reassemble it), we disassembled one of the modern smartphones – Lenovo S90.
As a child, after reading the story “The Old Man Hottabych”, I was especially impressed how Hottabych, with the flick of the fingers of his left hand, creates a telephone “from a single piece of the finest black marble.” However, this phone had one drawback – it did not work: “In that case, it’s clear why this phone doesn’t work,” Volka said. – You only made a mock-up of the phone, without everything that is supposed to be inside. And the most important thing is inside the apparatus ”. It was then that I was interested in the question of what is inside the phone. One such telephone – though not made of marble, but made of Bakelite – was on my parents’ desk, and I, driven by curiosity, took it apart. After assembly, I had a lot of unnecessary parts left, and my parents had to buy a new phone.

Over the past three decades since that time, technology has changed significantly. Inside the Lenovo S90, you will not see what I saw: no carbon microphones, no magnets with wire coils and cardboard speaker cones, no pulse dial with gears, a spring and a split flywheel of a centrifugal speed regulator. In a modern smartphone, there are not so many parts into which you can disassemble it at all – they are arranged in fairly large non-separable units, and the parts are packed inside the case extremely compactly. It is not always possible to disassemble and then assemble your smartphone yourself. So Popular Mechanics did it for you.
