"The Galaxy S21 delivers the flagship Samsung experience in a phone that's much more pocketable (and affordable) than the top-end S21 Ultra.The triple-camera system is incredibly capable, Samsung's One UI 3.1 software is chock-full of features and settings to mess with, and I've not once missed having expandable storage."
"Despite not boasting the same camera credentials as its pricier sibling, the Samsung Galaxy S23 Plus will remain a top-tier handset for several years thanks to its industry-leading processor and magnificent display. It may prove an attractive proposition for Galaxy newcomers in the market for a big-screen all-rounder."
