There's no reason to buy Samsung these days.
If No MicroSD = Not buying a Samsung. That was the main reason to have a great phone with expandable storage. Why bother having high quality cameras if you do not have enough space to use / save it. When shooting in 4K video, you cannot count on cloud or even having cell coverage for extra space.
