It only has two hinges and,this, two folds. Why is this called a TRI-fold?
"Tri-Fold" refers to the number of panels folding in on itself, not the number of hinges. Similar to the "Tri-Fold wallet" there are 3 panels folding in, and the "bi-fold wallet" has 2 panels folding in. ;)
Then why isn't the Galaxy Z Fold 7 the Galaxy Z Bi-fold 7?
