Brazilian person here, when I moved to Europe I was baffled I couldn't find shops that fixed electronics. Like I wanted to get my Android phone charging port replaced, I literally couldn't find a shop in my city willing to do the repair.
I eventually went back to Brazil and had it fixed there and replaced the battery. Freaking phone lasted 8 years on my very clumsly hands, still works even. The fix cost me ~30 usd plus the battery cost.
Yes, it's something extremely valuable, an expensive portable, and the new models all just keep getting worse and worse. There's no reason not to fix them.
It's also a repair that demands some amount of training. I imagine people fix a lot of things without getting them to a shop.
Hackers are down voting my comment. My question to them: If you could get paid twice the salary per hour to repair expensive machines, would you spend your time repairing mobile phones?
Everybody wants that juicy, juicy cheap labour, but nobody wants to be the cheap worker.
And you can train those teenagers to do things which are much more profitable. If they have the dexterity and other skills needed to work on cell phone electronics, then they can work on other electronics.
If it was a good business, then there would be cell phone repair shops on every corner in Europe, like you have in other parts of the world where that makes sense.
