On the surface, the Galaxy Z Fold 3 doesn't have many big upgrades. Instead, it is made up of a ton of smaller upgrades. Which makes the Galaxy Z Fold 3 a really impressive smartphone.
Cheaper than its predecessor, IPX8 rated for Water Resistance, Slightly lighter than Fold 2, Both displays are 120Hz now, Multi-tasking has improved, More apps optimized for foldables now
