Crappy move by Apple. Last year they gave both the 11 and 11 Pro the same RAM. No excuse to give the 12 4GB, but I’m not surprised. The 11 Pro should have had 6GB of RAM.
Prey tell how much ram should Apple give the iPhone 12 then? 12gb, 24gb, 1024gb, 2,000,000gb?
Once you demand more ram you never shut up and enough is never enough.
