Install It If You're an IT Professional
If you're an IT professional you might want to install the Nexus 5X's Android O beta in order to test systems and applications ahead of the official release.
Enterprise problems are extremely common after major Android version upgrades. We always heard and see complaints about Exchange and various other apps and services.
IT professionals who support end users at a company will probably want to get familiar with the Android O update to stress test for bugs and problems.
Trying out the software will also help prepare IT professionals for the inevitable support calls and trouble tickets from Android O users later this year.
If you get well acquainted with the Android O beta you'll be able to confidently answer questions and hopefully handle any problems Android O your co-workers or clients encounter.
