Saving a phone number is a basic but critical feature of any smartphone, and Xiaomi Redmi 9 is no exception. Device owners often face the need to quickly record a friend, colleague or delivery service number, however, the MIUI shell interface can have its own characteristics that distinguish it from standard Android. Proper data retention ensures that you do not lose important information when you change your device or accidentally reset your settings.
In this article, we will discuss in detail all possible ways to add entries to the phone book on Redmi 9. SIM-Understanding these differences will help you organize (address book) as efficiently and securely as possible.
Before we get into the instructions, it’s worth noting that contact management in MIUI is centralized through the Contacts system app and synced with your Google account, allowing you to flexibly customize your display and sorting. We’ll look at both standard methods and nuances that even experienced users often overlook.
Application interface Contacts and basic settings
The call and address book management app in Xiaomi Redmi 9 looks concise but hides a lot of useful features. When you first start or after a reset, the system may suggest choosing an account to automatically sync, which is an important step, since it determines where your data will physically lie.
At the bottom of the screen, you usually have tabs to switch between all the numbers, favorite contacts, and groups. The top of the screen contains a search bar and a menu button, often presented as three dots or profile icons, and that's where the display settings and filters are hidden.
- 📱 Contacts tab – the main list of all saved numbers, sorted alphabetically.
- ⭐ Favorites – Quick access to frequently used numbers you have added manually.
- 👥 Groups – the ability to sort people into categories (Family, Work, Friends) for easy messaging.
It’s important to understand that the interface may vary slightly depending on the version of MIUI installed on your Redmi 9. However, the logic of the work remains the same: all editing and creation activities are performed via a floating menu or add button.
⚠️ Warning: If you don't see some contacts, check the filtering settings. SIM-maps, and the main records are hidden.
Step-by-step: Creating a new contact
The process of adding a new number to Xiaomi Redmi 9 is as simple as possible for developers. First, you need to open the Contacts or Phone app and go to the appropriate tab. In the lower right corner of the screen, there is a bright button with the plus sign or a person’s silhouette.
When you click on the add button, you'll see a data fill-in form, which will not only include your name and number, but also additional information like your email address, your job title, your company, and even assign a unique ringtone to your call, and the Name field is a must for future search.
☑️ Pre-conservation checks
Special attention should be paid to the save location field. By default, the system often suggests saving a number to a Google account, which is the most reliable option, but you can manually change this value by clicking on the arrow or the name of the current storage.
After filling in all the necessary fields, click the Save button at the top or bottom of the screen, the record will instantly appear in the general list, and if you make an error, you can fix it by opening the contact card and selecting the editing point.
| Field. | Description | I'll be sure. |
|---|---|---|
| Name. | Name of contact for display | Yes. |
| Phone. | Primary number for communication | Yes. |
| Warehouse | Reservation location (Google, Phone, SIM) | Yes. |
| Add a field | Data extension (email, address) | No. |
Selection of storage location: SIM, Phone or Google
One of the most important questions when making a contact on Redmi 9 is where to save it, and that makes it a choice to keep your data secure and transfer it to another smartphone, and let's look at the advantages and disadvantages of each option.
Retention on SIM-The card is an old method that has significant limitations, and the phone's memory card usually only has a name and a number, without the ability to add an email, a photo or additional numbers, and if the plastic card is damaged, all data will be lost.
The In-Phone (or Device) option allows you to store unlimited data with detailed information. However, if your Xiaomi Redmi 9 breaks or you decide to perform a full Hard Reset, all of those contacts will disappear forever unless you backed up separately.
The most reliable way is to save to a Google account, in which case your contacts are linked to an email, and when you log in to any new Android smartphone under that account, the entire phone book will recover automatically in a few seconds, providing full synchronization and protection against data loss.
What to do if your contacts are missing?
Pre-processing fields and details of contact card
Modern smartphones, including Redmi 9, allow you to create detailed profiles for each subscriber, not just recording a number, but creating a full-fledged card of a person or organization, and this includes adding additional fields in the form of creating a contact.
To expand, look for the Add Field button or the plus icon in the edit form, and you can select the type of data you have: work phone, home phone, fax, pager, etc. Add address, date of birth, website, and notes.
- 📧 Email – useful for sending emails directly from the call interface.
- 🏢 Organization – helps to group colleagues by place of work.
- 🎵 Melody – allows you to recognize the important caller even without looking at the screen.
Using these fields makes communication management more efficient, for example, you can set up Xiaomi to make family calls louder and work contacts ringtone-specific, all of which are available inside a contact card.
⚠️ Note: When adding a photo of the contact, make sure the image is square or the system will automatically crop it, possibly incorrectly.
Import and export contacts to Redmi 9
Often times, you need to transfer contacts from your old phone to your new Xiaomi Redmi 9, without having to type hundreds of numbers manually, and it offers convenient tools to import and export data via files or a direct connection.
The most popular format for transferring is the.vcf file (vCard), which you can export to the old device, transfer the file to the new phone and open it, and automatically prompt you to save all the records in the file.
To perform the import, go to the Contacts app, click on the menu (three dots or bars) and select Import Contacts. The system will prompt you to select the source: a file from the device's memory, SIM-Maps or accounts of other services (such as Outlook or Yahoo).
Exports are useful for backing up your phone book regularly and sending it to your own mail or to the cloud, which will be your insurance against technical failures.
💡
Use the QR-code "Businesscard Exchange" feature if both people are nearby, which is faster than dictating a number and eliminates errors in numbers.
Frequent problems and their solution
Despite the stability of MIUI, users sometimes experience problems with contact management, and one of the common complaints is duplication of records, which occurs when the same number is stored in SIM, Google, and phone memory.
To solve the doubles problem, Xiaomi Redmi 9 has a built-in unification feature. Go to the contact settings and find the item "Combine duplicates." The system will analyze the list and suggest that you pop the duplicate entries into one.
Another problem is that contacts don't sync, usually due to an unstable Internet or an error in your account settings, check if you have access to the network, and try manually running sync in the settings section of your Google account.
If contacts are gone after the system update, don't panic. The display filter is probably down. Go to the display settings and make sure that you check the "All Contacts" box or select the right account to show.
💡
Regular synchronization checks and no duplicates are the key to clean and fast operation of your Xiaomi phone book.
