How to stop apps writing to "Android" folder on the SD card?

I have a (seemingly) simple question to which I haven't found a clear answer to. My phone creates an "Android" folder on my SD card and I'm wondering if it could be moved into the phone's internal storage instead. I just got a new phone and it's got way more storage than my last phone, so I'd like to make the most out of it as I can, so I'd prefer that all the application data is on the internal storage rather than on the SD card. That's the way it worked on my old phone, so I'm a bit puzzled that it doesn't seem as easy to do anymore.
