Whenever I get an incoming call it is just showing unknown. No number is displayed and names are also not displayed though I have saved contacts in my mobile. But no problem for outgoing.
Recently I upgraded it to lollipop. It is fine when I upgraded but from the time I got my sim ported to other network(DoCoMo to airtel), im facing this problem. Did some troubleshooting like restarting the mobile and importing and exporting contacts to sim and internal storage and vice versa and I also saved my contacts in google account .But no luck.
It is driving me crazy. Please help me.
