Don't Install If You're Traveling
If you're preparing to travel or if you're currently on a trip, you might want to avoid installing Android Pie until you're back home.
Over the years we've spoken to travelers who wind up with a broken phone or a busted app/service because they installed a new operating system.
If you're on an important business trip or traveling in a city/country for the first time, having a functioning phone on hand is extremely important.
If you're out of your comfort zone, it's probably a good idea to wait to do the Android Pie upgrade until you're back at home base. That might be the hotel, but for many of you it's going to be at your house.
There's no reason to jeopardize a fun trip with family or an important business meeting with a software upgrade. The Android Pie update isn't going anywhere.
