Yeah. Even a smaller town will have a random repair shop where a guy will replace phone screens, solder in a replacement power supply, and he seemingly has some kind of connection that can get him all these parts from Shenzhen. A comparable sized town in America won't have anything comparable other than a Dollar General selling phone chargers.
I have a guy which can fix almost anything. But well, he has high paying job, and has 600k EUR apartment.
You can't expect him to waste weekend fixing something for pennies.
Unlike a guy living in shed, driving 20+ yo Daewoo Lanos.
A comparable town in the US would absolutely have a local or franchise repair business doing those things. What neither of them will have in abundance are shops replacing BGA modules as an upgrade. For that it'd be major cities only.
And the person at the repair shop typically has a Masters degree in electrical engineering or similar.
