Earlier quoted context omitted.
If it was a car you would have just taken it to the local repair shop and hopefully it's an affordable repair but phones don't have that and so when they die, and they all do, it's quite harrowing (unless you are super rich).
You definitely can repair your phone. There are repair masters who can replace chips on the board. This is common in Kazakhstan and Russia at least.
What's the typical income in this country, in America if you're talking about a $700 phone, and you make $70,000 a year it's not completely unreasonable to replace it every year.
But if you're making $15,000 a year, spending $30 to repair your $700 phone makes much more sense.
