facebook error invalid key hash for some devices

the error is only for devices which have facebook app installed otherwise for the devices which don't have facebook app installed, it's working properly.
And the hash key it is showing is not one which I have saved in developers site of facebook.

I would appreciate any help on this.
please refer image for screenshot of error

Answer

Add your Hash key to Developer Console of Facebook.

This issue might be happened because of key store.
