CES may be over, but Samsung wasn’t done with its announcements this week, revealing its new line of Galaxy S21 flagship phones a bit earlier than usual. There are three models once more, with the Ultra sitting at the top thanks to its large 6.8-inch screen. But Samsung isn’t the only one making phones now approaching the 7-inch mark, with even Apple scaling up thanks to its iPhone 12 Pro Max. Check out the table below to see how the S21 Ultra and Pro Max match up against another big handset we’re fond of, the OnePlus 8 Pro. And be sure to check out our hands-on right now, and review when it’s posted later on this winter.
