unless I put it in the freezer for like 10 minutes
Ok honestly... how did you come up with that? What compelled you to say: "Well my phone won't turn on, let's try the freezer". Did you try other appliances first? like the microwave, or the washing machine?
Honestly, I'm only semi being sarcasting. I am amazed by the creativity some people come up with when fixing their gadgets. Like the fact that we all instictively knew to blow on those stupid SNES cartridges, or how to bang the TV remote twice on the bottom so that it would work.
Also, I wish I had anything useful to say about your question. I simply wanted to comment on the beauty of your solution.
