Honor 8S and Umidigi A3X

[Pimenov]

I tried to install Dolphin on my father's Honor 8S but it rejected due to 32-bit android.
But one guy with another Helio A22-powered phone Umidigi A3X

plays NFS games with setting tweaks because it's with 64-bit android.

So why are Helio A22-powered smartphones often 32-bit?
Choosing a 32/64 bit $100 phone for Dolphin seems like losing/winning in a lottery.

It's a cost reason. It's cheaper for phone manufacturers to ship budget devices with 32-bit Android. Though that trend seems to be changing in recent years. If you're looking for affordable dolphin option checkout the Moto G Fast, it's on sale for 150 currently I believe.
