Have tried everything that support has suggested (they even said they had no solution) and still can't keep an internet connection with my Samsung s21. I can get texts, notifications and it will count my steps, but it won't let me do anything else, when I try to add apps thru the gallery it tells me there's no internet connection. If I check in my Bluetooth connections, it tells me an app is needed to use device. They just won't recognize each other. Waste of money!!
