Check With IT
If you use your Galaxy S7 or Galaxy S7 Edge for work you should think about checking in with your IT department before you download Android Oreo.
Enterprise issues are extremely common after major Android upgrades and we've seen Galaxy S8 and Galaxy Note 8 users complain about a variety of them in 2018. We expect issues to strike Galaxy S7 and Galaxy S7 Edge users as well.
If you've got an IT department, use it. They might be able to give you valuable advice and essential feedback about the apps and services you depend on to do your job.
If you don't have an IT department at work, you might want to track down a co-worker using Android Oreo on a Galaxy S7 or a similar device.
If you don't know anyone using Android Oreo on a Galaxy S7 or another Galaxy phone, you'll need to poke around the web for feedback about specific apps and services.
