Secure Folder App is not Supported

[Prashant_H]

I have used Samsung M21 Mobile Device and I need Secure Folder App in Google Play Store 

But The Error Shows "Your Device is not Compatible with this Version"

I tried these follows

1) Clear the Caches of Google Play Store 

2) Safe Mode 

3) Memory Storage Clear the Caches

4)Reset the phone 

Again Shows Your Device is not Compatible with this Version...

Solving This issues
