The Samsung Galaxy S10 5G isn't out yet but one of the first, if not the first, teardown videos just popped up. It takes you through the whole process of disassembly and shows off all the internals of the phone so if you like hardware videos, go ahead and watch it.
Of course, since the phone has a glass sandwich design, a heat gun is needed to loosen up the adhesive holding the back plate before prying it up. The first thing we see is the triple-camera module along with the 3D ToF sensor and the plate used for wireless charging. A couple of cables need to be removed before proceeding too.
The rest is business as usual but there are a few takeaways from this - you have to remove almost everything before you can access the display for changing (at least that's what we can see from the video) and there's a mysterious unpopulated connector on the mainboard that hints at a different version or a carrier-specific one with some additional hardware. Also, there's nothing unusual of the cooling solution - it consists of a thick layer of thermal paste making contact with a small copper heatsink.
