Wanted to take a moment and address an issue Many folks have been having getting One UI 2.0 installed on their Unlocked Note 9 (N960u1).
Samsung, in it's infinite wisdom, released a limited number of OTAs. However, there is a very simple way to get up to date. SmartSwitch.
SmartSwitch is not just for swapping data etc. from phone to phone. It's your portal to the Samsung update servers, directly. So, here's what you do. Using a Windows PC / Laptop, download the SmartSwitch application from Samsung. Once it's downloaded and installed, connect your phone via a USB cable (make sure you unlock your phone so it can communicate with the PC). Once connected, the PC app will identify the version of Android your device is running. If there are updates available, you will be prompted to download and install. Otherwise, it will inform you that your device's software is up to date.
Once One UI 2.0 is installed, reconnect the phone to the PC and get the February Security patch too, as the update to Android 10 comes with the January Security patch.
Once you have the updated OS and Feb patch installed, be sure to Wipe The Cache Partition¹!!
You will need to go to the Google Play Store and Galaxy App Store update your apps.
Hope this helps those of you who have been waiting patiently for an OTA.
¹ Wiping the Cache Partition.
"Typically," it would not be absolutely necessary to do this with "just" a Security Patch. But this is an OS update, so it is HIGHLY recommended that you do take the few moments it will take, and get it done. Clearing the Partition is your first line of defense against having future issues. So, without further ado...
1) Turn phone OFF
2 Press and hold the Bixby button and the Volume UP button. With them pressed and holding, Press and hold the Power button until your device boots into Recovery Mode.
3) Use the Volume Down button to select "Wipe the Cache Partition"
4) Press the Power button
5) Press the Volume Down button
6) Press the Power button to select "Yes"
7) Press the Power button to Reboot Device Now
You are the proud owner of a Samsung device. So it's always in your best interest to perform a Cache Partition wipe after ALL OS and even Security Updates. Samsung tends to add some bug fixes and improvements in the monthly update, and not mention anything about them. So while just a Security Update would not necessarily require the wipe, it's just an ounce of prevention. Clearing the Partition will help prevent some issues that can arise after an update is installed.
As of this writing, I have not yet seen the March Security update available for install. But rest assured that it is not too far off. So if you see that an update supposed to be released and your device has not received it, take a moment to check SmartSwitch via your PC.
The process is the same for all Android OS Samsung devices.
If there is an Update available, you'll be prompted.
*Cache Partition clearing is basically the same across all Samsung devices.
