This DIY fix serves as a testament to the extent users will go through to desperately fix a significantly broken device. It also probably hints at how much trouble the Xperia Z3+, a.k.a. Xperia Z4 in Japan, is giving its users. And some users just can't take the heat anymore. One in particular, ingeniously applied a bit of physics and chemistry to help dissipate the heat that the smartphone is generating using nothing but common kitchen foil. And apparently, he wasn't the only one who has thought of that solution.
