Losing an important number or having to change your smartphone is always stressful, which can be reduced to zero if you set up your backup correctly. Owners of Xiaomi, Redmi and Poco devices often face the question of saving the phone book when switching from a phone to a phone book. MIUI It's on HyperOS or just for reliability. It's the most reliable way to protect data from Google's cloud, because it doesn't depend on physical safety. SIM-map or memory of the gadget.
The modern Android operating system, on which the shells of the Chinese manufacturer are based, has built-in synchronization mechanisms that are often ignored by users. If your numbers are stored in the device’s memory, rather than tied to an account, the risk of losing them when you reset or break down is extremely high. In this article, we will discuss in detail the migration of your records so you can be sure of their security.
The copying process takes only a few minutes, but saves hours of time to reconnect in the future. We will look at the standard system tools, work with export files and the nuances of the MIUI shell. It is important to understand the difference between on-premises storage and the cloud to choose the best option for your situation.
Preparation of the device and account verification
Before you start moving data, you need to make sure that your smartphone is logged in to the right profile. Without an active Google account, synchronization is impossible, as it is the link between the device and the server. Check the Internet, as data transfer requires a stable connection.
Go to your device’s Settings and find the account section. Depending on the firmware version, the path may vary slightly, but the logic remains the same for all Xiaomi models. Make sure you’re logged into the exact inbox you plan to store information, especially if you have multiple.
- 📱 Make sure that only one active Google profile is installed on your device to avoid confusion.
- 📡 Check the stability of the Wi-Fi network connection for fast data transfer.
- 🔋 Charge the battery of the smartphone to a minimum 30-40% in case of long-term synchronization of a large amount of data.
☑️ Checking before synchronization
You should pay special attention to where your numbers are physically located right now. SIM-In the memory of the phone, in the internal memory of the phone or already partially in the cloud, we need to make the source data available in the Contacts app on the smartphone screen to be successfully transferred.
Analysis of current contact vault
The first step in the migration process is to determine the current location of records. Xiaomi owners often use a standard app from Google or a proprietary solution from MIUI, and the interface may differ. Open a list of all numbers and select any random entry to view the details.
In the contact information window that opens, look at the box where you have your account or your save location, and if it says "Phone," "Device," or "Device Memory," it means that the data is local and needs to be moved, and if your Gmail address is listed, the sync process is probably already set up correctly.
⚠️ Note: If you see contacts with a tag «SIM», You can't sync them directly to Google, you have to import them into your phone's memory and then move them to the cloud.
The number of records also plays a role, and if you have dozens of them, it's instantaneous, and if you have hundreds or thousands of entries in your phone book, the system can affect more CPU resources when you first unload, and then you'd better wait for the Wi-Fi connection to keep mobile traffic out of the way.
Instructions for transfer through the Contacts app
The easiest and most reliable way to move data is to use the built-in contact management functionality, which requires no third-party software installation and works on all current versions of Android. The algorithm is simple enough, but requires careful choice of the target directory.
Open the Contacts app and find the management menu, which is usually hidden behind three dots in the corner of the screen or called by a swipe. You will need to find Contact Management or Import/Export. In the MIUI interface, this section is often displayed in a separate settings menu within the application.
Select the option “Move contacts” and the system will suggest selecting a source (for example, “Phone”) and destination (target) – your Google account. Once the selection is confirmed, the copying process will begin, which takes from a few seconds to a couple of minutes depending on the volume.
- 📂 Open the control menu in the contact app (three dots or gears).
- 📥 Select “Import/Export” or “Move Contacts».
- ☁️ Please specify the source of the phone and the recipient of Google (your email).
- ✅ Confirm the operation and wait for a report of successful completion.
In some cases, the system may request permission to access the account to make changes, which is a standard Android security procedure that must be verified. Once the operation is complete, the old entries in the phone's memory may remain or disappear depending on the type of operation chosen (copy or move).
💡
If you have two Google accounts, make sure that when you select a recipient, you specify the one that is the main one on that device so that sync will work automatically in the future.
Using a VCF file for backup
An alternative, but equally effective, method is to back up.vcf. This universal format is supported by all operating systems and email services, and can be saved to a computer, sent to an email, or uploaded to Google Drive cloud storage.
To create such a file, go to the contact settings and select Export, and you will be prompted to save the file to the device's internal memory, and once the file is created, it can be found through the MIUI or Files file manager in the folder where the export was made.
| Parameter | Description | Recommendation |
|---|---|---|
| Format | VCF (vCard) | Universal standard |
| Location. | Internal memory / root | Remember the path to the file |
| Size | Depends on the number of photos. | No photo weighs little |
| Security | Local copy. | You need to save the file separately. |
Once a file is created, you can open it and select the “Import” option by specifying your Google account as the target storage, which force you to upload all data from the file to the cloud, a method that is especially useful when you move from an iPhone or a button phone that does not have direct access to Google services.
⚠️ Note: Export file, stored only in the phone's internal memory, is not protected from loss when the device breaks or resets. Be sure to copy the created.vcf file to your computer or to the cloud.
Automatic synchronization setting
To avoid the need to save new numbers in the future, you need to set up automatic synchronization, which ensures that any contact you add is instantly in secure cloud storage, which is controlled by system services on Xiaomi devices.
Go to Settings -> Accounts and Sync (or "Users and Accounts"). Find your Google profile in the list and click on it. Make sure the switch opposite Contacts is activated (blue or green).
Also, check the settings of the contact app itself. In the app settings menu, find “Account for new contacts” or “Save to by default.” Select your Gmail address here. Now, when you create a new record, it will automatically go to the cloud, bypassing local memory.
What to do if the synchronization is suspended?
Periodically, the system may request re-authorization or display notifications of synchronization errors, usually due to a change in password or the expiration of security tokens, in which case it is enough to re-enter the password from the acca-unt in the system menu.
Solving problems and mistakes
Users may experience technical issues when migrating data, most often from overflowing account storage (although contacts take up minimal space) or duplicate conflict. Google can combine duplicates, but sometimes it needs to be done manually.
If you see a sync error message, check the date and time on the device. Incorrect system clocks can cause security certificates to fail and block the connection to Google servers. Set up automatic timing over the network.
Another common problem on Xiaomi is aggressive energy saving, which can stop the background sync process. Go to the battery settings, find Google services and contacts, and set the "No Limits" mode, which will allow the system to freely update data even in sleep mode.
- 🔄 Check if Google Drive storage is full (although the 15GB limit for contacts is hard to reach).
- 🗑️ Use the “Fix and Manage” feature on contacts.google.com to remove duplicates.
- ⏱️ Make sure the phone has the correct date and time.
Critical:
💡
Automatic synchronization is not a one-time action, but a constantly working process that requires checking energy saving settings and access to the network.
