Don't Install While Traveling
If you're about to leave on a trip or in the midst of traveling, you should avoid the Galaxy Note 8 beta.
The Galaxy Note 8 Android Pie beta is plagued by a variety of issues. There's also a chance the beta bricks your device or wipes the data stored on your phone.
If you move your device from Android Oreo to Android Pie beta you could wind up with a busted device/app/service and that's not ideal for traveling.
It's important to have a functioning phone while traveling in a place you've never been or during an important work trip filled with meetings.
If the Galaxy Note 8 is your only phone, it's a good idea to stay on official software for the duration of your trip.
