Everything is working well with my new Ultra watch, except for one major issue. Sleep data logged has been compromised, with a consistent gap (zero data recorded) between roughly 11:30 pm and 4 am (the actual duration could vary but the gap in the sleep data always occurs in this time window), every night. Actual sleep data is measured through the Galaxy Ultra watch that is connected to my Galaxy S23 Ultra phone. All the standard remedies suggested on the community site, as well as by Samsung itself, have been tried (both on the Galaxy S23 Ultra phone and the Ultra watch) but to no avail. I have read about similar issues with the Ultra watch sleep data, reported mostly by our Asian friends and Tech Radar has written about this issue as well. The fixes cited by Tech Radar in their article, to activate and then deactivate the power saving mode and also to update the Samsung Health app (both these are actually Samsung suggestions) do not work either. Unless Samsung fixes this issue soon, this will be a major disappointment and I will not be using the Ultra watch for my sleep data. An example of the compromised sleep data along with the Tech Radar article are presented below. I've contacted Samsung several times hoping that they will acknowledge the existence of this issue and also reassure their customers that they are working on a resolution for this, but they keep insisting that they have not heard of any such complaints from other Ultra watch users. They are asking me to mail in my watch for repair. I believe that it may not be a watch specific issue but a software issue related to their Health app. Have any of you in the Samsung community experienced this issue and if so, have you resolved this successfully? Thanks.
