Install for New Emojis
If you love to use emojis when talking to your friends and family, you'll want to download Android Pie soon after you get it.
The Galaxy A series Android Pie update comes with Unicode 11.0 which means it has some brand new emoji characters on board.
Before you download the Android Pie update note that people running older versions of Android won't be able to see the new emoji characters. They'll likely see a bunch of jumbled symbols instead.
