Ditto, beyond disappointed. Fairly new Sprint customer, former Verizon customer. They always got the updates last, now the tables have turned.. Normally don't care too much about updates, but this one allows you to connect a PS4 controller and stream directly from the console...
Android 10 now starting to roll out to the Note 9. Granted it is in India, but the point is Sprint's most current Premium device has yet to receive Android 10 compared to a device that is a year old. Seriously considering moving to another carrier that cares about the customer, security, and the money I am paying for this device.
I did update to Android 10 as well.
I could only find generic Samsung Android 10 changelogs but nothing specific to Sprint's Note 10 Android 10.
You can get the same info directly on your phone by going to Settings / System Updates and press on "Last Update" then click the dropdown arrow next to "What's New"
