I never bought a smartphone for myself, but I've seen 100 EUR smarthpones, and what you get is just a toy (unless you want to do your banking or login to e-mail on a Linux device with severely outdated kernel and no OS updates, which can't go for a few minutes without phoning home, wherever that is) More expensive ones are not significantly better, either, unless you pick a brand known for keeping up with security updates.
