The process of saving numbers on Redmi 9 may seem trivial, but it has its own nuances, specific to the shell from Xiaomi. the interface of applications and the logic of the system can differ from stock Android, which sometimes confuses beginners. Below we will take a detailed look at every aspect of working with the phone book so you can feel confident.
Basics of saving numbers in the app Contacts
When you first launch Xiaomi Redmi 9 or after adding a new one SIM-The system offers you to configure the display and save of records. MIUI, It has advanced functionality. To save a new number, the user just needs to press a button «+» Or make contact in the phone book interface, but that's when critical storage choices come up.
The recording creation window that opens at the top of the screen often displays the current account or storage. By default, the system may offer a save on the screen. SIM-You can transfer the number to another phone by simply moving the plastic, but you can't add photos, emails and other addresses if you choose to save to a SIM card. Saving the phone in memory without synchronization is risky: if the device breaks, the data will be lost irretrievably.
⚠️ Note: If you keep contacts exclusively in your phone’s internal memory (‘Phone’ or ‘Device’) without cloud sync, you risk losing your entire phone book when you reset your settings to factory.
To edit an existing record, you need to open it and click the Change button, and you can also change the priority storage if the system allows you to move, or copy the record to a more reliable place. Redmi 9 allows you to flexibly customize fields, adding birthdays, companies and notes, which is especially convenient for business contacts.
Syncing with a Google account: the most reliable method
Google’s ecosystem provides the most stable way to store data on Android devices. On Xiaomi Redmi 9, this process is integrated deep into the system. When you connect to a Google account, it instantly enters the cloud and becomes accessible from any other device that is logged in under your login, it can be a tablet, a new smartphone or even a computer through a browser.
To make sure sync is on, go to your phone settings. Find Accounts and Sync (or Users and Accounts). In the list, select your Gmail email address. Make sure the switch opposite Contacts is active. If the slider is blue or green, then automatic save is working correctly.
☑️ Checking Google Syncs
The great advantage of using Google Contacts is that you can restore deleted records, and it keeps a history of changes for 30 days, sometimes longer. If you accidentally delete an important number or it disappears after some kind of failure, you can go to contacts.google.com from your computer, select the Recovery feature, and roll back the status of the phone book to the desired date.
Also, when you buy a new smartphone or switch to another Xiaomi model, you don't have to manually interrupt hundreds of numbers. Just type in a login and password from Google, and the entire phone book will boot automatically. This saves hours of time and reduces stress when you change your device. For Redmi 9 users, this is the main recommended use case.
Working with SIM-card: import and export of data
Despite the development of cloud technologies, many users still store numbers on the Internet. SIM-card, especially when switching from button phones or old Android smartphones. Xiaomi Redmi 9 supports two SIM-So you can use these cards, and the system allows you to manage the records on each of them separately, and importing contacts from the SIM is the first step you should take when you set up a new device.
To do this, open the Contacts app and find the settings menu, often hidden behind three dots or the More button. Select Import Contacts. The system will prompt you to select a source — in this case, it will be yours. SIM-map (SIM 1 SIM 2) Then you need to specify the destination. As mentioned, it is better to choose a Google account or a phone memory with subsequent synchronization.
| Parameter | SIM-map | Google account | Phone memory |
|---|---|---|---|
| Limit of symbols in a name | Limited (often 20-30 SIM) | No restrictions. | No restrictions. |
| Addition of photo | Impossible. | Maybe. | Maybe. |
| Risk of data loss | Low (in case of SIM breakdown) | Minimum (cloud) | High (on discharge) |
| Additional fields | Only number and name. | Email, address, website | Email, address, website |
Exporting contacts back to SIM-The plastic card format is outdated and does not support long names, a second phone number for a single contact or an email address. When exporting, some of the information can be cropped or lost. SIM-Redmi 9 card is recommended for initial base transfer only, not permanent storage.
What to do if contacts are not imported?
Using Mi Cloud for Backup
Xiaomi has developed its own cloud platform, Mi Cloud, which is an alternative or addition to Google services. On Xiaomi Redmi 9, this feature is built into the system and allows you to create full device backups, including contacts, messages, notes and even desktop layout.
To activate the Mi Cloud contact save, open your settings and log in to your Mi Account. In the “Mi Cloud” section, find Contacts and enable synchronization. The advantage of this method is that it is fast within the Xiaomi ecosystem. If you buy another Xiaomi or Redmi smartphone in the future, data recovery will be as fast and conflict-free as possible.
However, you should consider regional features. Mi Cloud servers can be located in different countries, and depending on the region of registration of the account, the speed or availability of certain features may vary.In addition, free space in the Xiaomi cloud is limited (usually 5 GB), and if you make full backups of the system with photos and videos, the place can quickly run out.
An important feature of the Mi Cloud is the ability to view contacts through the i.mi.com web interface. This allows not only to recover data, but also to edit it from a computer if synchronization is enabled. For users who actively use Xiaomi technique, creating a Google + Mi Cloud bundle provides dual data protection.
Transferring contacts from other phones
When you switch to the Xiaomi Redmi 9 from another smartphone (be it an iPhone, Samsung or an old Android), you need to migrate data. MIUI has a built-in application called “Mi Mover” (or “Data Transfer”), a powerful tool that allows you to transfer contacts, apps, photos and settings over Wi-FiDirect without using the Internet.
The transfer process is as follows: on the new Redmi 9, select “I am the recipient”, and on the old device, install the Mi Mover app (if it is Android) or use the built-in feature (if it is an iPhone). QR-The code of the devices connect, and you select the category "Contacts." The speed of the transfer depends on the number of records, but usually takes no more than a few minutes for even a few thousand numbers.
An alternative is to use a.vcf file (vCard) on an old phone, which means you have to export all contacts to a single file, transfer them to Redmi 9 (via Bluetooth, messenger or other devices). USB-The system automatically recognizes the format and suggests importing the records into the selected storage, a method that works across almost any phone model.
⚠️ Note: When transferring contacts via a.vcf file, make sure you import them into your Google account, not locally, to avoid future data loss.
Managing duplicates and cleaning the phone book
When you use your smartphone, import data from different sources, and synchronize multiple accounts, you often have duplicate contacts. The Xiaomi Redmi 9 has a built-in tool to combine these records. When you open a contact, the system can suggest that you combine similar records if you find a match of names or numbers.
To manually clean, open the Contacts app, click on the settings menu, and select Contact Organization (or Contact Management). There will be a "Combine Repetitive Contacts" item. The system will analyze the database and suggest a list of take-ups to merge, which helps keep the phone book clean and avoid confusion when calling.
Also available on this menu is the option to remove contacts with empty fields or those that do not have a phone number (for example, residues from messengers or social networks). Regular cleaning not only frees up space (albeit minimal), but also speeds up the search for the phone book. On Redmi 9 with its processor, this is not so critical, but the order in the data is a sign of a competent user.
💡
Use the Favorites feature for the most important numbers. Adding a contact to your favorites places it at the top of the list and allows you to make one-touch calls from the widget on your desktop.
Frequent problems and their solution
Sometimes users are faced with contacts missing, new numbers not being saved or the phone book is not working correctly. One of the common reasons on Xiaomi is the limitations of the background activity of applications. MIUI aggressively saves battery power and can kill the synchronization process. To avoid this, look in the settings of the Contacts app and Google Sync, go to Battery and select No Limits mode.
Another problem is desynchronization after changing your Google account password. If you recently changed your password or enabled two-factor authentication, your phone may stop saving new numbers to the cloud by continuing to write them locally, in which case you need to re-enter your account in your phone settings, and check if Google storage is full (15 GB limit for all services), as this blocks sync.
If contacts are displayed but without names (numbers only), check the display settings. Contacts has a filter that can hide certain groups or accounts. Make sure you check the "All Contacts" box or select the right display sources. Often, after updating MIUI, filter settings can be reset.
💡
Regularly checking your sync settings and having access to the Internet is a guarantee that your contacts will always be safe and relevant on all devices.
