Samsung please to bring the the option/ feature where has you can place your finger on the heart rate sensor and flip your device over and it started to read it. Please to always consider people who can't afford a new device or a smart watch and wishes to use their Galaxy devices that has the HR on it. Many additional features needed within the Samsung Health app, if it's not a hilighted feature let it be there still, for has for me I still uses my Galaxy Note 9 and my Galaxy Watch 1 2019 so keep us in mind too.
