The S20 does away with Samsung's heart rate sensor, a feature that's been with the S series for a long time. Many people use this feature a pulse oximeter with Samsung's Health app, so you may be surprised to find the S20 no longer supports the feature. If you don't have a fitness band or smartwatch with this functionality and absolutely need a phone that can check your pulse, the S10 and S10+ are the way to go. . . .
