Samsung officially starts us off with the Galaxy Fold
Samsung launched its first consumer-ready foldable smartphone in 2019. The device was teased relentlessly, though when it launched, it landed with a smack. The Fold, which started as a device with a measly 4.6-inch display, opened up like a book to reveal a 7.3-inch Dynamic AMOLED inside. It also had a protective plastic film on the inner display, which some reviewers unknowingly pulled off. Samsung then retracted those review units and relaunched the Fold a few months later with a fix.
