Why Jerry's 'bend test' is non sense on the KEYone
First of all I want to say that I am a fan of JerryRigEverything's channel, I think he is amazing, and I've learned a ton of cool stuff out of his tear down videos. Secondly this is my opinion as a Mechanical Engineer.
What Jerry calls a 'bend test' does not have any fundamentals regarding a part with induced fractures, meaning for the analogy this is several parts put together whereas a slab phone is one part with a stress applied along its length.
I don't believe BlackBerry has anything to fix about this "issue". It's just pretty expected that if you apply that kind of stress where two separate parts have been joined they will fall apart. Furthermore, that's a very unlikely situation to happen in real life. I think Jerry should avoid that specific test in any phone built similarly as the KEYone, and instead do drop tests, that resemble what could actually happen to a phone in daily usage.
Lastly, you can't even compare that kind of stress (flexion) in a part that has a welded joint to the same part that doesn't have it, and here we are talking about one of the toughest joints a part can have.
My conclusion: Jerry's 'bend test' makes no sense whatsoever in the KEYone in particular, the situation is very unlikely to happen in daily usage, and no user should be concerned about the result of test.
P.S. My KEYone arrived a few days ago, and I am loving it!!!
