It's a black round dot - top right hand corner, arrived with an update about 6 weeks ago, I have no other explanation for it, there wass nothing mentioned about it via Samsung... if it's a camera, as I suspect, why?
Unfortunately, a screenshot does not pick up the black circle that may or may not be a camera🙄however, there is no explanation for it's existence that I can find - although, that's not hard to believe, I'm not all that tech savvy🤷♀️thankyou for your response, but, no screenshot makes it difficult to get across what it might be...
Thanks for clarifying. The S10 camera has always been in the top right corner. A recent update removed the ability to hide the camera by adding a black bar to the top which I am currently following up with.
A temporary solution to this would be to use 3rd party apps.
