Changing a smartphone or initially setting up a new device always starts with restoring a contact list. For users of the Xiaomi ecosystem, this process can seem confusing due to the features of the MIUI and HyperOS shell. The system offers multiple storage spaces, and choosing the wrong option can lead to the loss of important information when resetting settings.
In this article, we will discuss in detail how best to save phone book entries, how to set up automatic synchronization and what to do if contacts disappear after an update, learn how to manage duplicates and use cloud services to protect your data from accidental deletion.
Understanding the logic of how address books work on Redmi and Poco will save you time in the future. Proper storage is the foundation of safe smartphone use. We will look at both standard tools and hidden features that not all owners of brand devices know about.
Choice of storage location: SIM-card, phone or account
The first thing that a user faces when creating a new record is choosing a place to save. Modern smartphones offer three basic options, each with its own critical features, and this choice determines the availability of the number after flashing or losing the device.
Storage for SIM-The limit of the characters in the contact name is often limited, and saving additional fields such as email or address is impossible, and if the SIM chip is damaged, it will be extremely difficult to restore data without specialized equipment.
⚠️ Warning: Keeping contacts solely in the device's memory ("Phone") is dangerous. If you reset your settings to factory or break the motherboard, all records will be irretrievably lost.
The most reliable option is to save in your Google or Xiaomi Cloud account, and contacts saved in the cloud are automatically restored on any device immediately after entering your login and password, which ensures continuity of communication and protection from human errors.
When you add a new number, the default system can offer to save to the memory of the phone. To change this behavior, you need to manually select the desired account in the drop-down list when you create a contact, this action will set priority for all subsequent records.
Step-by-step: Adding a new contact
The process of creating a new entry in the phone book on MIUI is standardized, but it contains nuances that allow you to expand the functionality. First, open the standard Contacts or Phone application and go to the list management tab.
Click on the + icon or the Create button, and a form will open where you need to enter your first name, last name and phone number. The system will automatically offer formatting, but you can manually type it in an international format for ease of use of instant messengers.
☑️ Verification of contact data
Then comes the important step of adding more information, click "More" to open the additional fields, where you can specify your work email, your address, your job title, and even add a contact to your favorites for quick access through the sidebar.
After filling in all the fields, click the Save button at the top or bottom of the screen (location depends on the HyperOS version). If you choose to sync with Google, the recording will instantly go to the server and become available on tablets or PCs.
Synchronization and backup of data
Automatic sync is a key feature that must be activated immediately after a smartphone is purchased, ensuring that any changes to the phone book are duplicated in the cloud, and without this step, the risk of data loss remains high.
To set up, go to Settings → Accounts and Sync. Select the Google account that is used on the device. Make sure the switch opposite Contacts is activated. In the same menu, you can start forced sync by clicking on three dots in the corner of the screen.
Xiaomi device owners also have access to their own Mi Cloud, which is integrated deeper into the system and allows you to restore contacts even without activating Google services, which is relevant for some regions. → Mi Account → Mi Cloud.
💡
Enable Wi-Fi sync for contacts so you don’t waste mobile traffic when you update large lists.
Regularly creating local copies will also be useful. In the Contacts app, you can select “Import/Export contacts” through the settings menu. Save the.vcf file to the memory card or send yourself to an email, which will create a restore point for a specific date.
Transferring contacts from other devices
When you switch from another Android smartphone or iPhone, you have a massive data transfer problem. Manually entering hundreds of numbers is inefficient and can be problematic. Use built-in migration tools to speed up the process.
For Android and iOS devices, Mi Mover is the perfect app, which is pre-installed on all new Xiaomi devices, and it transmits contacts, photos, apps and settings over Wi-Fi Direct without using the Internet, a process that takes several minutes even for large archives.
If you have a backup file in.vcf or.csv format, it can be imported directly. Open the Contacts app, select Import/Export, and specify the source of the file (device memory or device memory). SIM-The system automatically recognizes the format and offers to match the fields.
| Transfer method | Source of data | Speed. | The need for a PC |
|---|---|---|---|
| Google Account | Any Android/Web | Instantly. | No. |
| Mi Mover | Android / iOS | Tall. | No. |
| File.vcf | Memory/Email | Medium | No. |
| SIM-map | Old phone. | Low. | No. |
When importing from an iPhone via iCloud, make sure the contacts are exported in vCard format. The file must be downloaded to the new Redmi and opened through the standard contact manager.
Managing duplicates and combining records
A common problem with syncing multiple accounts is the appearance of duplicates, and the same person can be logged twice, once from Google, once from Telegram or WhatsApp, which clutters the list and makes it difficult to search.
The MIUI shell has a built-in tool to address this problem. In the Contacts app, click on the menu (three dots or stripes) and select "Clean" or "Combine Repetitives." The system will analyze the list and suggest combining entries with the same numbers or names.
Linked Contacts is also available, which allows you to manually combine multiple profiles into one, for example, if a colleague has a work and personal number, you can link them into one card, a single name will be displayed on an incoming call, and both numbers will be displayed on the contact card.
Use a display filter to clean up your garbage, and in the contact display settings, you can turn off the display of entries without numbers or hide contacts from certain folders (for example, from the messenger cache), leaving only the main phone book.
Solution: Contacts are not saved or missing
Sometimes users are faced with a situation where a new number is not written, or the list suddenly empty. Most often the reason is an overflow of the app cache or a synchronization error. Check if there is free space in the device's memory.
If contacts are lost after a system update, don't panic. 90% of the time, they're in the cloud. Go to contacts.google.com or i.mi.com from your computer, where you can see the full history of changes and restore the status of the phone book to any date in the past (up to 30 days ago).
⚠️ Warning: If you see a blank list of contacts, check the filtering settings. Perhaps accidentally activated mode display only contacts with the SIM-card-free.
In case of software failures, cleaning the Contacts and Contact Storage app data helps. Go to Settings → Apps → All Apps → Contacts → Memory → Clear the data. This will not delete your records if they are synchronized, but reset the display settings and cache.
Hidden codes for checking contacts
If the problem persists, try to delete and add a Google account again, this will force a full reboot of all data from the server, and make sure that the date and time on the device are set automatically, as time desynchronization blocks a secure connection to the servers.
