Good day, some time ago I wrote on the forum about an error in the health application.
It’s hard for me to describe it in English. my english is not good but i hope you understand 
The Samsung Health app does not display heart rate data between 11:00 pm and 12:00 am if a person sleeps, the data is not displayed for that hour.
But if a person is awake until 11:20 pm., then the recording in the application is written there and ends, for example, at 11:21 pm. before the person falls asleep. after half a night, even during sleep, he records normally further. the error is only in the period between 11pm-12am.
thank you very much for your understanding, I have asked several people and they have the same error. I live in the Czech Republic.
Or who should I contact about this issue?
Hi,
I believe there is a new Health update that is to be released soon that addresses several known issues.
However this is not the right forum for reporting this.
I would recommend you use the Samsung Members App for feedback
or
go to https://www.samsung.com and depending on your location
either → Click on Explore Tab → Click on Community
or
Scroll all the way down to the bottom of the page and under support is a link to the community

hi thank you, I wrote him about two months ago. they only wrote that I should do a factory reset. that’s what I did, of course, but then I checked on Samsung member, and more people said they had the same problem. so nobody does anything about it. and it’s quite funny that such a mistake happens in such expensive devices and in such a company. it’s a small mistake, but it is. Thank you for your time, I hope they fix it sometime. 
Check for a Samsung Health update, I was told one was released today.
Let me know if it is fixed.
