Don't Install If You're Traveling
If you're preparing to travel or if you're currently on a trip, you'll want to stay put on Android Oreo for the time being.
We almost always hear about travelers who wind up with a broken phone or a busted app or service because they installed a new version of Android.
If you're on an important business trip or traveling in a new place, you probably want a fully functioning phone.
If you're not at home, it's probably a good idea to wait to do the Android Pie upgrade until you're back at home.
That might be your hotel, but for many of you that's back at your house.
