Samsung's first foldable smartphone, Galaxy Fold, did not have a smooth start.
However, the company is speculated to bring more foldable devices in the coming year, with one version featuring a bendable glass display.
Tipster Ice Universe said that Samsung has built an ultra-thin glass cover for its upcoming foldable phone which would result in a flatter and less wrinkled screen, Engadget notes.
The rumour falls in line with Samsung's recent trademark for 'Samsung Ultra-Thin Glass'. It remains to be seen if the glass cover would actually help make the purported Galaxy Fold 2 less wrinkly and more durable.
