Wait for The OTA If You Aren't Comfortable
The Galaxy Note 9 Android Pie update is rolling out slowly and it'll take weeks, if not months, to hit every single device on the planet. If you don't want to wait for your Galaxy Note 9 Pie update you can manually install the software ahead of time.
Now that the official Galaxy Note 9 Pie firmware is out, Galaxy Note 9 users can skip the OTA (Over-the-Air) roll out and install the operating system right now.
If you're feeling impatient you might be tempted to skip the OTA. However, if you feel uncomfortable with any part of the manual installation process, you should wait for the OTA to arrive for your phone.
Manually installing software can bring unforeseen issues so if you aren't feeling confident about the move, hold off and wait.
