That's my point, though. They clearly can't make a game with the features of BotW - draw distance, effects, etc without major compromises.
Not personally aware of any games as full-formed as BotW that are running on $300 mobile sets. Though this could just be poorly optimized, which makes it more disappointing.
I don't think anyone has cracked making an open world game on a phone. But just from raw hardware specs perspective there are phones with more performance than the Switch.
