Many users encounter a problem when the address book turns into chaos of duplicate entries after changing a phone or transferring data. This happens because the system Android 9 may perceive the same number stored on the SIM card and in the Google account as two different people. The result is confusion when, when you receive an incoming call, you see several names or, conversely, cannot find the number you need.
Fortunately, the operating system offers built-in tools for putting things in order. The record merging process does not require installing third-party applications and only takes a few minutes if you know where to look for the necessary settings. In this article we will look in detail at all the ways to clear garbage from the call list.
It is worth noting that the menu interface may differ slightly depending on the model of your smartphone, be it Xiaomi, Samsung or OnePlus. However, the operating logic of the Contacts system application remains the same for the entire ecosystem Android. We will consider both automatic and manual methods for solving the problem.
Automatic merging of duplicates
The easiest and fastest way to restore order is to use the built-in automatic merging function. The system's algorithms analyze phone numbers, names and emails, suggesting that records that most likely refer to the same person be combined. To start the process, you need to open the “Contacts” application and go to settings.
In the management menu, you often find the “Contact Management” or “Contact Filter” item. Here you need to find the option “Merge duplicates” or “Merge”. The system will scan the database and provide a list of pairs that are recommended to be combined. All you have to do is confirm the action with the “Merge All” button or go through the list selectively.
This method is especially effective if duplicates arose after synchronizing with several sources at the same time. However, automation is not always perfect and may miss complex cases where names are written differently, for example, “Alexey” and “Lesha”. Therefore, after automatic cleaning, it is recommended to carry out a manual check.
It is important to understand that the function only works with those records that are available for editing. If some of the numbers are stored only on the SIM card without being linked to an account, the system may request permission to copy them to the phone memory for the merge operation.
Manual merging of specific records
If the automatic search did not help or you want to be 100% sure of the result, use manual merging. This method allows you to control the process and avoid accidentally merging different people with the same names. Open the contact card that has a duplicate and find the action menu (usually three dots in the corner of the screen).
In the drop-down list, select “Merge” or “Link Contacts”. You will see a list of all entries in the phone book. You need to manually find and check the boxes for those contacts that are copies of the selected entry. After selecting, confirm the action.
When merging manually, the system saves all information from both records. For example, if one “Ivan” had only a home number, and the second had a work and email, then all three communication fields will appear in the final card. This prevents you from losing important data during the cleaning process.
⚠️ Attention: Before starting a mass manual merge, make sure that you have a backup copy of your data. An erroneous merger of different people with the same names can lead to the loss of current numbers, and it will be difficult to restore the original state.
Working with contacts on a SIM card
Often records saved directly on SIM cardare often the source of duplicates. Unlike cloud storage, a SIM card has limited functionality and does not allow you to store complete data (for example, add a photo or a second number). To eliminate confusion, it is better to copy such contacts to the device memory or Google account.
Go to the settings of the contacts application and select “Import/Export”. Here you need to select the “Import from SIM card” option. The system will prompt you to select a destination account where the data will be transferred. After copying, the originals on the SIM card can be deleted to avoid repetition.
After transferring the data, it is recommended to check whether duplicates have appeared. If you have previously saved these numbers to your phone, you now need to merge them manually, as described in the previous section. This is a standard procedure when switching to a new smartphone.
Storing contacts on a SIM card is considered an outdated method in the era Android 9 and above. Cloud synchronization ensures data security: even if you lose your phone, numbers can be easily restored on a new device by simply logging into your account.
Use the “Favorites” function after merging contacts so that important numbers are always at hand on the main dialing screen.
Synchronization with Google account
The main storage for most users is account Google. It is he who acts as the central node where all data is collected. If you have synchronization enabled, then any change made on your phone is automatically applied in the cloud, and vice versa.
To check the synchronization status, go to your phone settings, the “Accounts” or “Users and Accounts” section. Select your Google account and make sure the switch next to Contacts is active. If synchronization is disabled, turn it on and click “Synchronize.”
The convenience of working with Google contacts lies in the ability to manage them through the web interface on your computer. By visiting contacts.google.com, you can see a complete picture of your address book. There's also a handy Merge and Fix tool that often works more accurately than on the smartphone itself.
The web interface lets you quickly edit names, add missing details, and delete unnecessary entries from a large keyboard, which is much more convenient than pointing at a small screen. All changes will be instantly reflected on your device with Android 9.
| Parameter | Phone memory | Google Account | SIM card |
|---|---|---|---|
| Photo storage | Yes | Yes | No |
| Multiple numbers | Yes | Yes | No (usually 1) |
| Synchronization | No (locally) | Automatic | No |
| Risk of loss | High (on reset) | Low | Medium (physical damage) |
Use of third-party applications
In some cases, the built-in system tools may not cope with complex takes, especially if the names are written in different languages or using different characters. Then specialized applications from the store come to the rescue. They use more advanced comparison algorithms. Google Play. They use more advanced comparison algorithms.
Popular utilities such as “Duplicate Contacts” or “Cleaner for Contacts” scan the database and offer flexible merge settings. You can set criteria: combine only if the numbers are exactly the same or take into account the similarity of names. This gives you additional control over the process.
When installing such applications, be sure to check the requested permissions. They need access to your contacts to work, but some apps may request unnecessary rights, such as access to the Internet or location, which is suspicious for an offline utility.
⚠️ Warning: Be careful when using third-party applications to clear contacts. Some of them may not process data correctly or contain advertising. Always make a backup before launching third-party software.
What to do if, after merging, a contact photo is missing?
It often happens that when merging records, the system gives priority to text data, and the image is lost if it was attached to only one of the duplicate records. In this case, open the combined card, click on the camera icon and re-upload the photo from the gallery. To avoid this in the future, try to add photos to the main post in your Google account, and not to local copies.
Preventing duplicates
To prevent the problem from returning, it is important to set up the right strategy for saving new numbers. In the settings of the Contacts application there is an option “Save new contacts”. Select your primary Google account there, not "Phone" or "SIM". This will provide centralized storage.
A list of linked accounts is also included. If you've ever used other services (for example Skype, WhatsApp or email services), they may have synchronized your address books with your phone. Disable synchronization of unnecessary sources in your account settings.
Checking your address book regularly, at least once every six months, will help maintain order. It’s easier to delete a couple of duplicates at once than to clear away the rubble of thousands of records after a few years. Use smart lists and groups for structuring.

Frequently asked questions (FAQ)
Is it safe to merge contacts if I'm not sure it's the same person?
If in doubt, it's best not to merge records automatically. When merging, the data is summed up, and if they are different people, you will lose the separation between them. In this case, it is better to rename one of the records, adding a clarification (for example, “Ivan Work”), and leave them separately.
What happens if I delete the contact after merging?
After merging, all selected duplicates become one record. Deleting this entry will lead to the complete disappearance of all data (numbers, addresses, mail) that were in the original duplicates. They can only be restored from the trash (if available) or a backup copy.
Is it possible to combine contacts from different SIM cards?
Yes, Android 9 supports working with two SIM cards. However, to combine them, their data must be read by the phone. It is best to copy contacts from both SIM cards to your Google account, and then merge in the cloud or in the common phone database.
Where is the backup copy of contacts stored?
By default, if synchronization is enabled, the copy is stored in your Google account. You can check the availability of a copy on the website contacts.google.com in the “Settings” -> “Export” section (in fact, this means creating a new copy) or simply visually checking the presence of all numbers in the web version.
Regular synchronization with a Google account is the best protection against data loss and the most effective way to prevent chaos in the phone book.
To summarize, you can to say that merging contacts on Android 9 is a necessary procedure for comfortable use of a smartphone. By using built-in tools and following simple data storage rules, you will save yourself from unnecessary headaches in the future. A clean address book is not only aesthetics, but also saves time in emergency situations.
