The reasons for the appearance of duplicates can be different: synchronization with several accounts, import from the Internet. SIM-Maps, errors in the update MIUI or even bugs in the company’s “Contacts” application».

In this article, we’ll look at all the possible ways to remove duplicates, from standard MIUI tools to manually cleaning through Google Contacts and third-party apps. We’ll focus on the causes of the problem so you can prevent it from happening again. If you have a Redmi Note 12, POCO X5 or Xiaomi 14 flagship, it doesn’t matter: the instructions are suitable for all MIUI 14/15 and earlier devices.

Before you start cleaning, make sure you have a backup of your contacts. This can be done through Settings → Google → Backup or export contacts to a.vcf file via the Contacts menu. Without a backup, don't start manipulating the phone book!

1. Built-in Connection Function in MIUI

Xiaomi has a tool to automatically merge duplicate records directly into the standard Contacts app, which works on all devices with MIUI 12 and later, including Redmi, POCO and Xiaomi 13/14 series.

4. The system will automatically find the duplicates and prompt them to combine. Click "Combine all" or select the recordings manually.

• 🔍 No duplicate records, the system did not find them.
• 📱 An outdated version MIUI — Update the firmware through Settings → The phone. → Updating the system.
• 🔄 Contacts are not synced – check your Google or Mi Account settings.

⚠️ Attention: After automatic merger, some numbers may be "lost" - for example, if there was a unique number in the double that does not repeat in other records!

If your Xiaomi model doesn’t have automatic unification (e.g. older versions of MIUI), try updating the Contacts app via Google Play. Sometimes new features appear earlier than in firmware.
