I’m facing very critical problem which I have never faced before.
I bought this phone from euronic an authorised samsung shop (italy)on 22/07/2019.
My phone is suddenly heating up.
I feel heat from the back, in the front also from its sides
I have tried some troubleshooting steps :
1.have updated the latest software version
2.wipe the cashe, Reboot the sistem ,
3.Passed in safe mode
-But nothing, no matter which app I’m using:whatsapp, YouTube, some game apps, it gets hot, very hot.
I really am afraid to use this phone.
Mine overheats too but I think because my note is cracked and flashes like crazy which could be causing mine to overheat but I'm also gonna use my warranty to get nine replaced so hopefully mine doesn't overheat like yours and you can fix the problem with your Note9
