Hmm...might need some more testing here. First pic is the OEM vapor chamber. Second pic is something I built myself, in my lab, with graphite.

If anyone has a line on where to get some replacement parts for this phone and can let me know where I can buy a new display for it, I would love the help. I want to rebuild a working device with the my vapor chamber replacement and test it on a full phone. There should be a big reason as to why Oppo spent the $ on a vapor chamber.

There it is. If you have any questions, let me know in the comments. I'm happy to chat about what and why. Also, I have quite a bit more pictures and information about the phone itself, and the teardown. Just didn't put all of it in here. Thanks for checking this out!
