We might have a few issues with Nokia and their phones, but there's no disputing they're made from hardy stuff. It's why we recall our first handsets so fondly - those drops barely scuffed the fascia, unlike today's fancy blowers.
Like a car manufacturer crash-test dummying their new wheels, Nokia (and other manufacturers) use rigorous test methods with their phones. Most, like this washing machine of pain, simulate real-life usage - seen in the video above, a pair of Nokia N8 phones rattle about to replicate the act of falling from a shirt pocket onto the ground.
Nokia claims they employ over 200 endurance tests with each new model, including forcing them into extreme weather situations of -40C to 85C and over; high humidity levels; and of course the good ol' button-mashing. [Nokia Conversations]
