Thank you for your comment. I went and checked them all and they all say they're working but still when I go to scan my CGM instead of vibrating shortly then a slightly longer vibrate then showing me the reading it just continues to make short vibrating sounds and then I get an error message to say it can't read the sensor. The sensor is definately working as when I click on the LibreLink app I can see my glucose levels but just scanning it doesn't work. Hopefully it will be something Samsung will sort with their next update 🤞
