Dear Friend Boki_Srb
As you remember - and it was relatively recent - everyone said that Primo on the QHD screen (2560x1600) would not go ... and what? - it works!
In this case - for LGG6 also works, but the Samsung S8 has a programmable resolution setting - and we both know that you can not put zip data at the same time 6 different declarations for the same interface.
I unfortunately do not have access to S8 (I have Note4) - so I will not try.
According to my thoughts - based on the design of the previous solutions - you have to do the version of data.zip for 2969x1440 resolution - and later programmatically adjust the screen to smaller.
IGO NextGen Galaxy S8 and S8plus work fine with dpi = 640 setting
In the evening I will still think about it - maybe something will come out. So far I'm still waiting for data from @tovid colleague - because we can not, unfortunately, exclude errors in installation of iGO after patches.
