Image won't finish downloading

[Felines00]

I currently have a galaxy tab (I think S7) and I recently wanted to download an image off of Google. Long story short the image has not finished downloading for an hour now. If I try to click on cancel nothing happens and I have no clue how to cancel this download. Help greatly appreciated!

If media isn't auto-downloading on your phone, try disabling these modes. For Android, go to “Settings -> Network & Internet -> Data Saver.” Turn it off. On iPhone, go to “Settings -> Mobile Data -> Mobile Data Options.” Turn off the toggle next to “Low Data Mode.”
