If China would open their economy to US companies in the same way the US was open to China pre-trade-war, then things could work.
As it stands China makes no secret about their desire to displace the US as the world's leading superpower, they've proven time and again they'll exploit any openings we give them toward that end. They don't want win-win scenarios, they want China-win-everyone-else-lose scenarios. It's long past time we stopped negotiating in good faith with bad actors.

On the other hand, good luck getting a Chinese smartphone in the US now. Better pony up your $1K+ for Tim Cook.
It is well understood that the ability of foreign companies to do business in China is extremely constrained. Considering that the topic is Android, it seems worth noting that basically every Google service is blocked in China by the Great Firewall.

What Trump has done is ripping the covers off the whole machinery, not only in domestic politics but also US international relations, down to the naked ugly cores.
Also last I checked Foxconn bought quite a bit of property in Wisconsin, even if they strangely haven't done much with it. Could a US company buy (and by buy I mean get one of those multi-decade leases, since the CCC technically owns all the land) property in China?
The US is far from the Captain America ideal, but from a trade perspective we've been a lot more fair with China than they have been with us.
