Here's how to build your own Samsung flagship off the shelf

Oh, the streets of Shenzhen, where you can be automatically fined for jaywalking and the fine extracted from your messenger/social app account before you have reached your destination. The other things you can buy there are electronics’ parts. Lots and lots of cables, boards, cameras, housing, memory and plenty of other geeky paraphernalia that would make Inspector Gadget proud.
The process, though, is worth watching in its entirety, and one can suddenly realize why it would be so hard for any company to move production completely out of China. Since iPhones are manufactured there, Scottie from Strange Parts deduced that more than half of the parts for sale in Shenzhen’s sprawling underground components market are for Apple’s finest, and the rest is for all Android manufacturers combined.
Samsung’s phones that are sold in the US are mostly made in Vietnam, for instance, which might explain why he had a hard time putting together a Galaxy S10, and went for the S9+ instead.
