good camera app?

Dec 2, 2017
I get much worse camera results on my Max 1 Prime helium than on my Mix1 lithium, using both the built in Mi camera app, Open Camera, and Gcam.

They both have the same camera sensor ov16880, and both are running EU 9.1.3, no other mods.
But Max1 is on Android 7.0 while Mix1 has android 8.0, of course.

I cannot use the same Gcam version on Max1 that I use on the Mix1, it just freezes up as I recall, but found an earlier, simpler version.

But even Open Camera produces much grainier photos of much poorer quality on the Max1.

Anyone have any good suggestions?
