I recently bought this phone for my dad and its upgraded to lollipop. But whenever any call is coming from an unsaved number, its showing "UNKNOWN NUMBER calling. " The phone happens to be brand new and i haven't yet added a google account or started using play store. Please help. Thank you for your kind attention.
This usually happens when your phone contract doesn't include caller ID. When you have caller ID, numbers will show and Google will do a search to show you who is the caller.
