The Contacts Backup and Restore app developed by UB Technologies is a reliable solution for users who have lost their contacts due to device errors or accidental deletion. This free app allows users to backup and restore their contacts offline, without the need for any additional app or internet connection.

One of the key features of this app is the ability to recover deleted contacts from Android phones and tablets with version 4.4 and higher. The app also allows users to restore contacts after a factory reset, although this feature may not work with all devices.

The app has a user-friendly interface, making it easy and simple to use. The backup file can be saved on the device itself and can be shared via email or other means. The app does not access or store any contacts, ensuring the privacy and security of user data.

To use the app, users can follow the step-by-step guide provided in the app or watch the instructional video. It is worth noting that the app does not collect any phone numbers or data, and if the app is deleted, the saved contacts will be removed as well.

Overall, the Contacts Backup and Restore app is a practical and efficient tool for users who want to ensure that their contacts are safe and protected.
