Does anyone else have a phone screen flickering problem since the latest update (S20 5G FE & Fit2)? I've been in touch with Samsung & none of their recommendations make any difference. Very disappointed, as many of the previous updates have also affected the functionality of the Fit2, and it is now nowhere near as good as when I first had it. Previous updates have also detrimentally affected the way my Fit2 records my Sleep, Heart Rate, Stress & Weight/BMI. Bring back my Fitbit Charge2!!
