I am having the zenfone 2 laser phone and I faced the issue with deleting the contact with No Name. After google I found some solution to delete the contact with No Name. I am sharing the details which I have followed to delete the No Name contacts in the contacts App.
1) Go to the Settings - > App -> Contacts -> Clear Cache and Data.
2) Go to the Settings - > App -> Contact Storage -> Clear Cache and Data.
