galaxy Note 9 problem

if that type of heat problem belongs to your device after update..,only 2 procedure is there 👉1..just do factory reset after update, 2..flash same firmware from Samsung service center

note:Samsung devices are more prone to be get heated, it's because of minimize radiation circumstance..don't worry..if your device has been heated, just follow normal steps👉turn off sync,wifi bluetooth, ect...don't play perticular game or any app through your device network for long time...put unused app into sleep mood...keep battery at auto optimization lavel...it's just troubleshoot....don't worry 👍👍👍

no issue on mine. just clear the cache partition in recovery mode.
