DJI 4k Drone Android app Won't Install- Samsung smart phone

I was excited to use my new drone which is super cool but could not load the APP. After much research and chat w/ support I was able to figure it out. The key is to turn off Google Play Store security, then load the APP then turn security back on. I hope this gets you closer to the solution. I could not show you the errors again as I have the APP now on my phone.
These are the basic steps:
go to the dji.com main site and find the page w/ downloads.
• DOWNLOAD for Android phone
• Error – something about your permissions wont allow to load the app.
• You need to turn off the security/permissions in google play store. Then load the app, then turn the security/permission back on.
Watch my video:
• See PIC of google play store icon examples.
• Go To Google Play store on your phone. PIC 1
• Click your profile icon top right to display some options.
• PIC 2- click PLAY PROTECT see PIC 3 on screen
• PIC 3- click upper right pin wheel then will see as in PIC 4
• PIC 4- toggle the two items OFF….this turns the protection off and allows the APP to load onto your phone.
• Load the Android APP
• Once loaded go back to the PIC 4 screen and toggle the two protection items
back ON
