Samsung has released a new video that shows the types of testing that Samsung’s folding cellphones go through in manufacturing. We can watch the new Z Fold 3 and Z Flip 3 immersed underwater, being tickled by the S-Pen for an extended period, or being folded and unfolded several times. Therefore, a film that attempts to illustrate the robustness of these new smartphones with foldable screens also falls short on the time front since different customers have been voicing worries about their Z Flip 3’s screen breaking for no apparent reason days.
