Thanks to leakage, let's try the latest Android Pie beta on the Galaxy S9, we already have a good idea of what the update has saved for Samsung's flagship forwards. As we will expect, Android 9.0 comes with a lot of noteable updates, such as a system tray dark theme and a brand new TouchWiz replacement called "One UI".
As it turns out, these leaks were just appetizers, as Samsung has started the official rollout of Android Pie beta for Galaxy devices today on November 15th. However, it is a catch, as the software update will only be available for unlocked S9 models in Korea, Germany and the USA, at least initially.
First, you need the Samsung + app. You can find it by searching for "Samsung +" with the Galaxy Apps app in your appbox or by clicking the link below and then selecting "Galaxy Apps" from the "Complete Action" dialog. Once you've reached the Samsung + Download Page, touch "Install" to grab the app.
Then open the Samsung + app and sign in with either your Samsung account or your Google Account (both data must already be stored on your phone). From here, touch your profile silhouette in the upper right corner and then select "Notifications" on the following screen.
If Pie is available for your device, you'll see a message on this page. Just tap this message and then follow the onscreen instructions to sign up for the beta application.
If you do not see the Pie Beta registration instant message in the Samsung + app, it's probably just a matter of time before it appears (assuming you have a supported Galaxy S9 variant, of course). So be sure to check out the Samsung + folder frequently, as there is only a limited number of slots available on the beta application.
Step 3: Update to Pie
After signing up for the beta version, open the Settings app and select "Software Update." From there, tap "Download updates manually," then wait a few seconds while the phone checks the update. When the update is found, it will be downloaded and installed automatically. This process takes up to 30 minutes, so make sure you have a charger at hand.
Remember, this is a beta- building, so you can encounter some bugs – even though Samsung has tested this firmware internally for a few months now, so it's pretty stable. However, the building does not transfer SafetyNet, so you lose access to some apps like Netflix and Pokémon GO. If it's too much for you to stomach, know that Samsung has said they're releasing the final public building of Pie to beta-eligible phones in January 2019.
