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 allow button:

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?

It is the stupid FileManager app. Once you stop it or remove it you can allow other apps to access the phone


Go to Settings\Apps\Birthday\Permissions and activate Contacts.

  • This is a neat idea, but the same screen overlay that stops the allow button working will also stop the permissions menu working.

  • Not necessarily. I had the same problem with another app and this procedure solved it
