All note 20 ultra buyers please read carefully.
It seems like Samsung has used both methods i.e. graphite thermal pads and vapour chambers, but it is a cause of worry as nobody would know which phone has what.
It is worthy to point out that our phone would heat up when taking pictures or playing less graphic intensive games like Mario Run. In fact, even Android Authority said in their review of the Qualcomm version of the phone, “The Note 20 Ultra warmed up all the time. Using the camera? The phone gets hot. Playing a game? The phone gets hot.” SamMobile pointed out “its temperature went up to 45-46C with just 5-6 minutes
If you are planning to purchase the Galaxy Note 20 or the Note 20 Ultra, it would be prudent to check the phone for thermal issues before purchasing as you never know which version you might get. It would be hard to figure out the type of cooling the phone is using, however, if the phone gets hot just by carrying out simple tasks, there is a good chance the phone is missing the vapour chambers and copper pipes.
It is also worthy to point out that Note 20 phones that come with a graphite thermal pad and face heating issues cannot be fixed via a software update as it is more of a hardware problem.
