So your contacts name dont show up in messages app or phone app?
The solution is rather simple. You must add your country code to each of your contact. Quite a tedious task to add so many country codes to so many contacts.
Now wishing if there was an app for that?
Say hello to Caller ID Fix app that allows you to quickly edit your contacts to add country code of your choice.
You can edit contacts in three different ways.
*Magical Update*
Magical update allows you to put same country code to all of your contacts which do not have any country code associated with it.
*Quick Update*
Allows you to update contacts with a single tap
*Manual Update*
The manual update allows you to select multiple contacts of your liking & then update those with single tap.
**Warning**
Make sure you backup your contacts before editing contacts as a precautionary measure.
