I did not change just nothing parameters, only jpeg to 100%. I use hdr+ always so 64 mpix is not supported. I think that 64 mpix is supported only with the original camera only without hdr+. I have Shamim 8.4 and Wicaya 8.1 both in my Zenfone 8. I use Wicaya with extremely low light condition, Shamim moderate low light and the original camera in normal day light.
