Not sure if I see the point of using a craft knife to scratch the case though. Nor the point of using a lighter to kill pixels on the screen. More for the sheer horror of it than anything.
The Iphone air couldn't be broken by hand either: https://www.youtube.com/watch?v=sQ56ve39l2I
The lighter test was originally to identify lcd vs led as they behave differently, but afaik nobody is even doing lcd anymore...
Watch the new iphone tests and you will see the point.
The phone still works at the end.
If that's the point, just chuck the thing into a boiling vat of acid and declare with a condescending voice "whoops, looks like they still haven't quite managed that boiling vat of acid problem despite knowing I test this on every new model". I'm sure that will get those likes and subscribes.
Or are people actually putting a lighter to the phone's screen during day-to-day use so that it matters how many seconds it survives?
His videos of scratching up phones with razor knifes and breaking them and such get views. It's a bit of a shame, because his other content is actually pretty good, but he built his channel doing those sorts of videos and they continue to pay the bills.
