They tried it circa 2012/13. It was a partnership with Microsoft/Nokia, meant to get people in developing countries hooked on Facebook at a very low price. The phone was crap though, even by dev county standards. I remember testing it, and everything took foreeeever.

On a bright side, it was the same time when FB put a ton of effort into improving their mobile web experience, realizing how bad it was on bad phones with slow networks.

Seems like they would need to have a compatible Android fork for this ... anyone know what pieces would need to be carved out and rebuilt for FB to mount a successful effort? Ie they don’t want this to benefit Google in any way.

Or is there some other viable mobile OS they could use? Not obvious to me.
