Lightweight contact search by phone number for devices that does not have this native functionality on contacts app.

Search through your contacts for some number that have called you or sent a text message but was not identified due to a number format different from your registration.
Also useful if someone called for your other devices that does not identified as your registered contact: You can search if that number might be part of your contacts.

The current search text considers only numbers for search but it will bring you contact phone numbers registered with '+' "-" for example.
