am using Note 10+ and am happy with it. it's not getting heat up even with intense use. am always connected with buds for calls and songs while working on my Note or in dex mode, using spen, and other heavy apps like lightroom and some other.. battery backup is good too. maybe it's your device that has some issue if you're facing any. get it checked with service centre. else its a beautiful beast. and the most productive device.
