Can't Download DJI Fly App on Galaxy S7

I have been pulling out my hair trying to get my new DJI Mini ready to fly. I keep having issues trying to download the DJI Fly app. Can someone give me a step by step? I normally don’t have issues with this stuff, but this one has me flummoxed.

Hi, I’ve downloaded it on a Galaxy S7, but not from Play Store. Scan the QR Code on the DJI website or on your drone documentation. Hopefully this should work.
