Check In With IT
If you're using your phone for work and you have an IT department, it would be wise to check in with the team to ensure that you can/should install the Android 6.0.1 Marshmallow update on your phone or tablet.
Enterprise problems are extremely common after major Android releases and we expect to see complaints as the Android 6.0.1 update hits more Galaxy devices around the globe.
Checking in with your IT department could provide you with essential feedback. They could warn you about potential problems with services or apps you might need for your job. They might also provide you with a go-ahead.
If there aren't any clear guidelines at your place of employment, check in with your IT people before you make the move. Otherwise, you might have to deal with some unnecessary headaches.
