Even more often, duplicates appear after resetting the phone to factory settings, when old backups are restored on top of new data.

In this article, we’ll look at 5 proven ways to combine the same contacts, from built-in MIUI tools to third-party apps, how to avoid data loss, what settings affect the appearance of duplicates, and what to do if contacts are not automatically combined, and at the end, answers to frequent questions and tips on optimizing the phone book.

⚠️ Important: Before starting work, make a backup of contacts through Settings → Google → Backup or export them to the file VCF. This will protect you from accidentally deleting important records.

2. Click on the three dots in the top right corner and select Contact Management → Combine Contacts.
3. The system will offer a list of duplicate entries, and in front of each pair will be a "Combine" button, click on it.
