Decide How to Install Android Pie
The Galaxy A Android Pie update is moving out slowly and it could take weeks for your upgrade to appear. If you're feeling impatient, you can download the update right now.
If you don't want to wait for the update to arrive Over-the-Air (OTA) you can manually install the Android Pie update onto your Galaxy A9, Galaxy A8, Galaxy A7, or Galaxy A6 right now.
If you're interested in manually installing the upgrade today, you should get familiar with the manual installation process.
If the process seems too complicated for your skill set, sit back, relax and wait for the update to roll out Over-the-Air.
