Definition: Galaxy Fold

Samsung's first foldable smartphone. Introduced in the fall of 2019, the Galaxy Fold uses a flexible OLED screen. The Fold is a 4.6" phone for making calls but opens into a 7" tablet. It includes three main cameras from 12 to 16MP and 512GB of internal storage. There is no microSD card slot.

Initially available from AT&T, the Fold is the most expensive smartphone on the market with a retail price just under $2000.

Fold, Z Fold2 and Z Fold3
In 2020, the second Fold debuted with a redesigned hinge and a "Z" in the name like the Galaxy Z Flip. The Fold2 is slightly larger at 7.6" vs. 7.3", and the outside phone screen jumped to 6.2". Video refresh increased from 60Hz to 120Hz.

In 2021, the Z Fold3 is similar to the Z Fold2; however, the Fold3 supports the Samsung S Pen and includes Qualcomm's newer chip (Snapdragon 888 vs. 865). Both models are 5G capable. See Galaxy Z Flip, iPhone Fold, FOLED, Galaxy S, Galaxy A and Galaxy C.

It's a Phone; It's a Tablet

When closed, the Fold becomes a rather thick smartphone but when opened, it offers the convenience of a 7" tablet. (Images courtesy of PCMag.com.)
