While I am very much impressed by the those videos showcasing how the foldable phone survived the various type of abuse and torturing, I would take them with a not a pinch but tablespoon of salt, as some of this video are for promotion use, which may be conducted in a controlled condition.
And, as usual, YMMV. I for one will be happy if it can last me for >2 years without any screen defect. My current Vivo X Fold + is 2 months to 2 years but both screens almost gone liao, even I handle my phone with tender loving care.
