Undo an Update

Is there a way to undo the update 7.1.1 I hate the way it makes my phone look I think I was on marshmallow or something like that

Welcome to Android Central! Based on your other post, I'm assuming you're asking about the Galaxy J7, correct? You can't roll back system updates easily on any phone. On Samsung phones, at least you can use Odin to flash the previous firmware: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html
