Have Your Login Info Handy
Before you install Android Oreo on your Galaxy S7 make sure you've got all of the login information for your popular apps and services handy.
There's a chance Android Oreo will log you out of your apps and services. And if you haven't had to login to them for awhile, you might've forgotten your login ID or password.
If you need an app or a service that day for work or school, this could become an issue. Even if you don't need access to an app or service right away you might have to waste time tracking down the information instead of getting started with Oreo.
We recommend writing down or storing your important login data somewhere before you install Android Oreo. It could save you some time.
