Samsung was having a rough start when it began pushing Oreo to Galaxy devices. Eventually, the Korean company went ahead, updated its flagships to Android 8.1 and now it is migrating the more affordable phones to the new OS version.
According to some Indian sources, at least eight phones are scheduled to get Android Oreo in December - Galaxy A9 Pro, Galaxy C7 Pro, Galaxy C9 Pro, Galaxy J7 2017, Galaxy J7 Neo, Galaxy On5 (2016), Galaxy On7 (2016), and Galaxy On7 2018.
Samsung noted the update schedule change, which is one way to salvage the reputation in such situation. Other phones that should receive Oreo are the Galaxy Tab S3, Galaxy Tab A (2017), and the Galaxy J7 Max, although they are scheduled between August and November.
To see if an update to Android Oreo has already arrived at your Samsung device, you should head to Settings, then scroll down to Software Update. You can tap on Download updates manually or turn on Download updates automatically, so you don’t bother with checking all the time.
Just got my A9 pro 2016 Oreo upgrade (6-Jan-2019)... All seems well
Andriod 8.0 with Samsung UI-9.0 Experience update is already available for Samsung A9-Pro.
C7 Pro & J7 Pro Oreo 8.1 is December. (Sorry for the previous similar repeat comments).
