I don't know if this helps but my Note3 used to have this issue and heated up a lot around the SD card slot right after booting up and would reboot and reboot. Pulling out the sd card helped a little, but to get it to NOT reboot, I would put it in the fridge or put a cold can of drink on top of the sd card area with the battery cover off. The phone would reboot every second day or so and I would need to fridge boot it again.
This was shi77ting me heaps and I was close to giving up on my Note3 when the 4.4 OTA update came thru.
After the update, the Note 3 became rock solid and I was getting 500+ hr up times without itself rebooting. it only reboots now because I shut it down and I cant remember it rebooting by itself since the kitkat update. I love my Note3 now and run it rooted (Kingo Rooted), with SDfix, and dont wish for any update that might upset this rock solid stability.
My note3 is the N900 Exynos 5420 version.
My Note10 is the N605 SD800 version and it runs 4.3 very solid and I'm not keen to upset it with a kitkat update as im happy with the way it is.
