How do i stop upgrading my software

[Android Central Question]

A notification came up to upgrade my firmware and because of the space i do not have enough to for my other apps. I have already clicked the Update button but it hasnt downloaded yet.There is a pause button i already clicked it but there is no cancel button.The megabytes have already been saved and i dont want that.How can i stop this and make my devce as it was before. Ive got the Samsung galaxy j5 2015.

Welcome to Android Central! I would just go through with the update, and then see how much free storage you have afterwards. A system update typically doesn't increase the amount of internal storage used by the system by a big amount.
