Just saw that the Beta is out in South Korea for a limited run.
What's the ETA for Android 10 for Note10+ USA release? I'm excited for some of the new features
There is no Official confirmation release date from Samsung but It is expected to be out on Monday October 14. See the link For more info:
Hope that helps.
In the US you have to have the unlocked (no carrier branding) version of the Note 10. If you do as soon as the beta is available you will see a notification in the Samsung Members app.
