Hello Seabee, thanks for asking! When a software update is officially released, the date you receive the update varies by carrier, region, and device model. On some devices, you'll receive a notification about the One UI update. But other times, you may need to do a manual software update. If you still haven't received the One UI, you should check if a software update is available.
1.To check for a software update, navigate to and open Settings.
2.Search for and select Download updates manually.
3.If a software update is available, follow the prompts to install the update.
You can always give us a call at 1-800-SAMSUNG if you are still having issues. We're here to help. ^Elizabeth
