I also have the same issue. My issue started recently in month of end Jan or first week of Feb 2024 with z flip 3. I called Samsung support, they can't resolve this issue and recommended to upgrade to z flip 5. I got it on Mar 1 and setup on Mar 3. Still the same issue continues. This is very frustrating. I think some upgrade during this timeframe is buggy. Its unnecessary upgrade even my last phone just around 2 years old. I called again today, they are placing new order. Not good experience with Samsung recently with z flip. I am not sure how they will settle this issue and newer order payments. Very frustrating.
