Install Pie If You've Got Android Oreo Problems
If you're dealing with problems on Android Oreo, and you can't seem to find a fix, you should probably install Android Pie. It could help you turn things around.
The Samsung Galaxy S9 Android Pie update isn't perfect. There are bugs and performance issues the company and its carrier partners need to work out. That said, it could improve your device's performance in several ways.
Some Galaxy S9 users are noticing improved battery life and a smoother user interface. Some Galaxy S9 users who were experiencing random reboots on Oreo aren't seeing them on Pie. This isn't surprising.
Android updates, particularly major releases like Android 9.0 Pie, have been known to iron out common performance issues like severe battery drain, reboots, lag, and issues with connectivity (Wi-Fi, Bluetooth, cellular data, GPS).
If your Samsung Galaxy S9 is tied to a specific carrier, there's a good chance your carrier will tack on additional bug fixes to your version of Android Pie.
For instance, T-Mobile's Galaxy S9 Android Pie change log notes that the update comes with "various bug fixes and system improvements."
Samsung's version of Android 9.0 Pie also comes with a few changes to Device Maintenance, now called Device Care.
The company says performance modes are now streamlined and integrated into Power saving modes making it easier than ever to get a handle on key areas of your device's performance.
All in all, if you're unhappy with Android Oreo's performance on your device, give Android Pie a shot. There's a good chance you'll notice an improvement.
