> I could be wrong, but I recall in many developing countries phones there are many teenagers who code on their phone because laptops (even tablets) are prohibitively costly.

Yes, I see that a lot here in the far south of Morocco.

> They might be wiring their phones up to some cheap keyboards, which is technically possible but I don't know if they're doing that.

They do. Adapters are about $2.

Why do that when bluetooth keyboards are cheap these days too? For like $11 you can get a bluetooth keyboard, which would most likely just work...

I could also see some of them using a cheap tablet for the larger screen, but I've also run into teens who use their phones exclusively.

It may be $11 here in the US, but it might be harder to get and more costly in a developing nation. In which case, if it is easier to get that $2 adapter and an e-waste keyboard, that likely makes sense for them
