Contact Number Fix is a free Android app developed by Michael Yos. It falls under the category of Utilities & Tools and is perfect for travelers and those who call abroad frequently. This app is designed to help you manage your contacts' numbers easily and efficiently.

The app allows you to select contacts with numbers that need to be fixed. You can edit the selected numbers together and add the country code as well. The new numbers will be saved to the contacts. The app also allows you to restore the last change made, but only the last one. Therefore, it is recommended to check the changes made with a few contacts at first.

The app is new and does not require an internet connection to function. You can delete numbers until a specific index, insert the first characters, add the country code, and remove hyphens. However, some phone-books may still display hyphens even after removing them.

Overall, Contact Number Fix is a simple and powerful app that can make contact management hassle-free and efficient.
