Solved! Smartphone suggestion required

Any good phone with min 3GB RAM and OS version should be Android Nougat 7.0

Very very limited number of vendors have made switch to Nougat. If latest OS is a priority then Google Pixel is what you need to be looking at.

one plus 3 (mine updated to 7.0 over the weekend. )
