LG doesn’t have the best of track records with firmware updates. The latest example is the Android 9 Pie update for the LG V20 which has just begun seeing in South Korea. The phone launched back in 2016 with Android 7 Nougat and received Oreo over a year ago. The new update is currently exclusive to Korean users and there’s no word on when it will be available elsewhere for now.
LG V20 Android Pie update changelog (translated):
Meanwhile LG also announced its plans to update several other devices to Pie by the end of Q4 2019. These include the LG Q9, G7 One and the K40. The company also confirmed it's planning to release a stable build of Android 10 for its LG G8 ThinQ before the end of the year. LG did mention that all of these update targets are solely for the Korean market so there's no confirmation as to the international availability.
Of course this article does not mention in the changelog that Android 9 removes call recording feature. So Android 8 is the world's best mobile operating system.
even though am not in korea but i got the andriod 9 updates working veryfine
I hope Android Pie will be released this December for all variant
