Samsung reckons it has ironed out the death-inducing creases on its Galaxy Fold but is continuing to put the smartmobe through stress tests before a rescheduled September launch.

The foldable screen of the $1,980 device fell short on quality control in early reviews back in April when reports emerged that the screen malfunctioned and in some cases just died. The May release date was then shelved.
