I'd be impressed if emulators are winning against big-tech in the spam wars. But perhaps there's spam uses that don't require the best antidetection.

If emulators worked, what's the point of those giant phone farms?

I don't know anything about this, so take it with a grain of salt.

I am just under the impression that a cheap real android is the fastest cheapest way to get a trustworthy-looking device for spamming purposes.
