The Galaxy Z Fold2 will come with a 5G support, a 7.6” 120 Hz display when unfolded with Ultra-Thin Glass on top.
Samsung has also notably improved the conventional external display and it now takes the entire front side of the phone when folded.
The main camera setup looks like it will be borrowed from the vanilla Galaxy Note20 with its three shooters and an LED flash in the upper right corner, but no additional sensors.
We expect Snapdragon 865+ chipset, coupled with up to 12 GB LPDDR5 RAM. 5G connectivity is likely to be both on the sub-6 GHz and mmWave bands.
