Unknown number displayed when receiving calls

[Wes1]

Each time I receive a call it shows unknown number, even if the number is saved in my contact list.

Try settings-apps-all-contacts,force stop and clear data. Do the same for your phone app.

Does not work

Boot in safe mode and check if the same occurs.

Still does not work.

Does this happen for all of your contacts? Where are they stored?

[Wes1]

Yes, on my phone.when I call out then I see there name and number only when receiving calls it just says UNKNOWN.

Can you perhaps contact your network and ask for help there too?

[Wes1]

I don't even want to contact them,they going to say that I must send the phone in. Thanks for your help though.

I suspect there might be something on their side. I would suggest you to perhaps try a different SIM card.
