Last month I bought nite 20 ultra day first I noticed the phone is heating if I talk some one 4 to 5 min at ur ear u feel very uncomfortable like heating on data also the same even rarely im using video or calls three times I had taken remote assistance 2 tines visited service center the problem is same service center saying didn't find any issue and customer care saying goto service center even if u kept in pocket without using the phone heating im not using any third party software professional im also electrical engineer since past 15 years im using different model of Samsung phone note past 5 years im buying every year I never feel before this kind of issue . I requested to samsung there is some manufacturing fault and change the set but not agree. Im really very disappointed , im suggesting to every one before buy think twice .
