Today I noticed strange behavior on my test phone, which is Nexus 5 with Android 6.0.1.
After opening test app that asks for permission to read contacts
allow button is not working - after tapping on
allow nothing happens, but
deny works perfectly:
Also when I check
Never Ask Again, it completely disables
Not sure what is happening here, but same app works perfectly on my OnePlus2 which uses Android 6.0.1 too.
The only strange thing about my test phone is that it does not have sim card currently.
Note that both phones have Google Account attached with same synchronized contacts.
I am wondering what causes this?
