I’m sorry but are you seriously saying Xiaomi is better privacy wise than Samsung?

Did I say I recommend Xiaomi for privacy? I’m just answering your question, and since you mentioned “Third World country,” that brand pops on me. They’re cheap, they’re functional, and last up to a day. Privacy? That I don’t know of. Most smartphones collect data anyway, unless you replace it to GrapheneOS, or any privacy-focused custom ROM.

Regarding of unlocking device, I’m just using a disposable phone number and email on my Xiaomi Account. That’s it.
