Don't Install iOS 12.4.3 While You're Traveling
If you're in the middle of a trip, we recommending holding off on updating to iOS 12.4.3 until you're back.
Over the years, we've heard many horror stories from people who decided to upgrade while traveling with family, friends, or co-workers.
We've heard about apps (like the Camera app) breaking, email issues, problems with maps and GPS, and a whole lot more.
These issues aren't the end of the world if you're at home base, but they can be very problematic if you're dependent on your phone or tablet for business or getting around in an unfamiliar city.
If you are traveling away from your comfort zone and your backups, we recommend holding off on the upgrade until you're back to your hotel or house.
iOS 12.4.3 could wind up being great for you and your device, but you don't want to ruin a personal trip or put an important business meeting in jeopardy.
