The dock of the Nintendo Switch is supposed to house the console when playing at home, recharging it and the Joy-Cons, and it also hooks it up to a TV. Since the dock performs so many functions, you would think that Nintendo would have designed it better, but we have been hearing about problems since launch.
Ever since launch we have heard reports of how the dock is scratching the display and also that it is warping the console. Not cool.
It has been a few months since the Switch was released, so by now you would think that Nintendo would have tried to address the issue. Maybe they could change the material of the Switch to prevent it from warping, but it appears that they are not addressing this. Reports from NeoGAF, Twitter, and Reddit have owners in Japan who are reporting that their consoles are warping too. It is a warped situation for sure.
Because of how the gap between the dock and console is so narrow, heat is unable to escape properly, and this means that the console only gets hotter the more you use it, which leads warping. You could maybe use third-party docks which seems to have been designed much better. Hopefully Nintendo fixes this soon.
