mapillary works fine on Android 4.4.4, 5.1, 5.1.1 and Android 6.0 for me.
You can try to fetch the .apk direct from mapillary.com website and test with it.
I have the same issue, and I have tried to download using the direct link, both from the Mapillary home page and from the above link, but I got an error:
“Error (403) It seems you don’t belong here! You should probably sign in. Check out our Help Center and forums for help, or head back to home.”
I have signed in Dropbox, but I got the same error.
Is there any other way to install the app in Samsung J5?
I have downloaded from here
and the latest version works fine
