OLED displays can be flexed. Having a flexible (scratch-resistance sacrificed) digitizer made the Fold display flexible. I wasn't hyped for the Fold, and deservedly so. Obviously this would have took some time, but people were getting gassed over this for no real reason.
"Looking at the empty chassis of the Galaxy Fold is quite a sight. It really is a feat of engineering"
Says it all
iPhone X is a much more impressive engineering. It comes with dual battery, and logicboard on both sides.
This fold's guts looks so ugly.. and unoptimised usage.
That is quite an impressive engineering feat right there. Now waiting for a teardown for the still-to-be-launched Huawei Mate X.
