Galaxy Tab A messing up since software update

[Android Central Question]

My tablet updated automatically a couple weeks ago..it's Android version 7.1.1. My photos wont show up, it wont move photos from one folder to another. There's just a blank screen many times. Nice...why do updates usually make things worse? Lol. Very frustrated.

My Samsung Galaxy A has downloaded an update to Nougat. I do not want to update. The notification comes up every half hour or so and is annoying.
How do I turn off this notification or better yet delete the update that is waiting to be installed?

You typically can't, unless you can turn off all system notifications. Oreo gives finer control over certain system notifications, but in Marshmallow, I don't believe you can turn off just the system update notification. You'd probably have to root the device and disable the system updater app -- I don't know the details, so you might want to check over at the XDA-developers.com forums, which is a good resource for this kind of thing.
