With note series from note 2 onwards and upgraded during release, after long samsung made necessary changes in upgrade or resale value which we observed from note 10 to note 20. Happy with note 20 ultra but i feel it shouldn't note go beyond 5 inch. Yes me talking for slide mechanism to go from 5 to 7 inches. Ofcourse with new spen features, ir blasters, under display camera, no side curve as it create problem while making note , rear camera settings in top middle so it stand firm while writing, thanks
