How to combine contacts on Xiaomi Redmi 8: a complete guide with pictures and tips

Xiaomi Redmi 8 – a popular smartphone with functional firmware MIUI, But even this one is not immune to the problem of duplicate contacts. Have you ever encountered a situation where the same person is displayed in the phone book two, three or even five times, SIM-map, import from backups or data porting errors. In this article, we will discuss all working ways to connect contacts on Redmi 8 – from standard tools to hidden features and third-party applications.

It's important to understand that duplicates don't just clutter up the list - they can lead to loss of important data (for example, if you're editing the wrong contact) or crashes when calling. We tested each method on Redmi 8 with the latest versions of MIUI 12.5 and Android 10, so the instructions are up to date for 2026. If you have a different version of firmware, check compatibility in the relevant sections.

Why do you have duplicate contacts on Xiaomi Redmi 8?

Before you start to unify, it is worthwhile to understand the causes of the problem. On Redmi 8, duplicate contacts usually occur because of:

• 🔄 Multiple syncs with different accounts (Google, Mi Cloud, Exchange) for example, if you added a contact manually and then it automatically pulled up from Gmail.
• 📱 Imports from SIM-A map or an old phone, often when you transfer data, you create copies of existing records.
• 🔄 Backup errors if you've re-established contacts from backup MIUI Google Drive may have been an older version of the records.
• 🤖 Contacts malfunctions, sometimes databases get corrupted, and the system creates duplicates instead of updating existing records.

On Redmi 8, the problem is compounded by the fact that MIUI does not block synchronization of duplicates by default. For example, if you have autosynchronization enabled with Google and Mi Account, the same contact can be stored in both clouds and the system will display it twice, and duplicates often appear after a firmware update or reset.

Method 1: Connecting contacts through the standard Contacts app

The easiest way is to use the built-in MIUI tools, which are root-free and do not require any additional software installation.

1. Open the Contacts app (an icon with a person’s silhouette on the home screen or menu).
2. Press three points (⋮) in the upper right corner and select Contact Management → Connecting contacts.
3. The system will automatically find possible duplicates, and in front of each contact, there will be a "Unite - press it to confirm."
4. If the automatic scan didn’t work, use manual mode: tick duplicate records and click Combine at the bottom of the screen.

Note that MIUI has a limitation that you can only combine up to 10 contacts at a time. If there are more takes, repeat the procedure until the list is completely cleared. Also check that the combined records have the same name and surname, otherwise the system may not recognize them.

Check for backup copies of contacts

Close all background applications (especially messengers)

Connect to a stable Wi-Fi network

Make sure the battery is more than 30% charged

⚠️ Note: If some data (such as additional phone numbers or email addresses) is missing after the merger, check the Recycle Bin in the Contacts app. You can recover deleted fields within 30 days.

Method 2: Sync and merge with Google Account

If the duplicates are due to synchronization with Google, the problem can be solved through the Google Contacts web interface. This method is suitable if the majority of contacts are stored in Gmail:

1. Open your browser on Redmi 8 or your computer and go to contacts.google.com.
2. Sign in with the same account that is linked to the phone.
3. In the left menu, select Dubbley, and the system will show all the repeated entries.
4. Click Combine All or select specific duplicates for manual merge.
5. Once combined, return to Redmi 8, open Settings → Accounts → Google, and enable Contact Sync.

The advantage of this method is centralized management: all changes will apply to all devices associated with an account. However, be careful: if you accidentally combine the wrong contacts, it will be difficult to cancel the action. Also note that Google Contacts may not recognize duplicates if they are stored in different accounts (for example, part in Google, part in Mi Cloud).

Method 3: Using third-party applications for mass unification

If the built-in tools failed, you can use specialized utilities. For Xiaomi Redmi 8 suitable:

• 📱 Simpler Merge is a free application with a simple interface that automatically finds duplicates by phone number, email or name. Supports packet combination (up to 50 contacts at a time).
• 🔍 Contacts Optimizer – a utility with advanced filters, allows you to customize the criteria for finding duplicates (for example, ignore differences in the register or spaces).
• 🛠️ Cleanup: Duplicate Contacts is a preview app for the merger, useful if you're afraid of losing data.

Check reviews and ratings on Google Play before installing – some apps may contain ads or request excessive permissions. On Redmi 8 with MIUI 12.5, Simpler Merge is more stable than others, but requires permission to access contacts and SMS (to recover from the backup).

💡

Before using third-party applications, export contacts to a file VCF: Open "Contacts» → ⋮ → «Imports/Exports» → «Export to file. This will help to recover data in case of an error.

⚠️ Note: Some contact-unification applications (e.g. Duplicate Contacts Remover) may delete data instead of a merger. Always check that Merge mode is selected rather than Delete mode).

How to avoid the appearance of doubles in the future?

To prevent the problem from recurring, set up Redmi 8 according to the following rules:

1. Turn off autosynchronization for unnecessary accounts: Settings → Accounts → Select an account (Google/Mi) → Contact Sync → Turn off sync with only one primary account.
2. Set your contact source priority: Contacts → ⋮ → Settings → Contact display → Select your primary account
3. Clean the Contacts app cache regularly: Settings → Apps → App management → Contacts → Clear the cache
4. Use one storage format. For example, if you prefer Google Contacts, import all contacts there and disable the save on the site. SIM-map or in Mi Cloud.

It is also useful to periodically check doubles (once every 1-2 months) through the built-in tool. MIUI Google Contacts: If you move contacts between devices often, use the format. VCF (vCard – it better preserves the data structure than exporting through SIM-map.

Problem Solving: What to do if contacts don’t join together?

Sometimes the merger process can end in error, and let's look at the typical situations and how to fix them:

• 🚫 The "Unite" button is inactive: Check that the selected contacts have at least one matching field (phone number, email or name). If there are no matches, the system will not allow the merger to be performed. manually edit one of the contacts by adding a common identifier (e.g., the same number).
• 🔄 After combining, the doubles reappeared: This is due to re-synchronization with the cloud. Disable autosynchronization (Settings) → Accounts. → Google/Mi → Contact sync), combine duplicates manually, and then turn on sync back.
• ⚠️ Contacts app freezes when combining: Clear the cache and application data: Settings → Annexes → Application management → Contacts → Clear cache / Clear data Attention: Cleaning the data will remove all local contacts (cloud will remain).

If none of the methods worked, try resetting the Contacts app to factory settings.

1. Go to Settings → Applications → Application Management → Contacts.
2. Click Warehouse → Reset settings.
3. Reboot your phone and try to reunite.

💡

If duplicates appear due to a contact database failure, the only reliable way is to reset the phone to factory settings (with a pre-backup!).
