When a phone book disappears completely after a system upgrade, accidental reset or strange freeze, it can cause panic in any smartphone owner. For users of the Xiaomi ecosystem, this problem can be especially relevant due to the specifics of the MIUI and HyperOS shell. However, in most cases, data is not permanently deleted, but only hidden due to synchronization errors or incorrect display settings.
Before resorting to complex recovery methods, you need to analyze the latest actions made with the device. Often the cause of loss is switching accounts or changing filtering parameters in the Contacts application. In this article, we will discuss in detail the algorithms for finding missing records and how to return them from cloud storage or local backups.
Today’s Redmi and Poco smartphones have powerful built-in data protection tools that you need to be able to use. Local copy or sync with Google can be a lifeline at a critical moment. The main thing is not to write new information on top of old memory sectors and act consistently.
The most common but common reason for numbers to disappear is a list filtering failure. The Contacts app on Android allows you to hide certain groups, such as numbers from the list. SIM-If the filter is not installed correctly, you will feel that the phone is empty, even though all the data is in place.
To correct this, open the Contacts app and find the settings menu, which is usually hidden under three dots or bars in the corner of the screen. In the Display settings or Contact Filter section, make sure that the tick is ticked against All Contacts. Also check if the Favorites Only mode or grouping for a specific Google account is activated.
⚠️ Note: If you see contacts but they are displayed without names (numbers only), check if the synchronization of names from the social network or the messenger that previously uploaded avatars and names is disabled.
Sometimes, a simple cleaning of an app cache helps. Go to Settings → Apps → All Apps → Contacts. Press Clear and select Clear Cache. This action is safe and will not delete your data, but can eliminate a software glitch that prevents the list from being displayed correctly.
📊 Where do you usually keep your contacts?

Recovery from Google and Mi Cloud
If local verification fails, the next step is to turn to cloud storage. Xiaomi users often have double sync through a standard Google account and Mi Account, which increases the chances of data being saved, since copies can be stored in different places independently of each other.
To check Google Contacts, you can use your browser on your computer or other device. Go to contacts.google.com, log in with the same account as your phone. If you have numbers, you can just select Settings on your smartphone in the Contacts menu → Google Contacts → Sync Now.
How does the shopping cart work in Google Contacts?
Deleted numbers don’t disappear instantly. They’re stored in an archive or cart for 30 days. Go to the Settings menu on Google Contacts and select Unchange Changes or go to Recycle Bin to recover deleted records.> Hidden text with details MIUI device owners should also check the Mi Cloud cloud. Go to Settings → Mi Account → Mi Cloud → Contacts. Make sure the sync switch is active.

These files are stored in hidden folders of internal memory and may contain a full copy of your phone book at the time of creation. To find such files, open the standard file manager (Conductor). MIUI → backup → AllBackup. It's where the.bak archives are stored. If you see files with a date preceding the contact loss, try recovering through the Settings menu. → The phone. → Reservation and rehabilitation. ☑️ Check local copies Open File Explorer Go to folder MIUI/backupCheck the date of creation of files.bak Try to restore through the settings: 0 / 4 You should also check the Internal Storage folder. → MIUI → cloud → Backup if you've used a local backup called Mi Cloud. Sometimes users forget that they've enabled automatic copy creation when they first launched their smartphone. Having one is the fastest way to get all of your phone numbers and related data back without having to go to third-party services. ⚠️ Note: When you restore from a local backup, the current data on the phone can be replaced with data from the archive. Make sure that the archive contains up-to-date information, or make a fresh copy of the current (even empty) state. SIM-Maps and other sources Often users save numbers directly to the SIM-The card, especially if you go from a button phone or an old device.In modern Xiaomi smartphones, import is often offered when you first start, but if you then refused, the numbers can remain invisible in the main interface. To import, open the Contacts app, click on the menu (three dots) and select Import Contacts"SIM-The system will suggest you to choose which account to save data to, you better choose your main Google account to avoid future losses. If you're actively using Viber, Telegram, or WhatsApp, they may have their own local copies of the address book. These apps often have a "Update Contacts" or "Sync" feature in their settings that will pull numbers from the messenger cloud into the device's phone book. Using third-party recovery apps If built-in methods don't help, you can use specialized software. There are PC programs and mobile applications that scan internal memory for residual database files. One popular database format in Android is contacts2.db. Searching for such files can yield results. Apps like DiskDigger or Dr.Fone can perform surface scans, but deep analysis requires a connection through the Internet. ADB The right to use the superuser. adb pull /data/data/com.android.providers.contacts/databases/contacts2.db This command (requires root) allows you to pull the contact database directly from the device for analysis on the computer, but this method is designed for advanced users, since improper actions can lead to complete loss of data or disruption of the system. 💡Using third-party software is only effective if data has been deleted recently and memory sectors have not yet been overwritten with new information. Prevention of future data loss In order to prevent this from happening again, you need to set up automatic synchronization. Make sure your Google account settings include contact sync, which is free, secure and works in the background, saving changes instantly, and it is also recommended to periodically make full backups to an external media or computer. Use the "Backup" function in the settings MIUI, When choosing to save to your computer or to cloud storage (e.g. Google Drive or Dropbox through third-party file managers). Regularly check where new numbers are saved. When creating a contact, the phone often suggests choosing the default save location. Prioritize your primary Google account, not your phone or phone memory. SIM-This ensures that even if the device breaks down or is lost, the numbers will remain accessible from any other gadget. MIUI? After major system updates, display settings are often reset or sync fails temporarily. First of all, check the Internet connection and force sync to your Google account. If it doesn't work, check the display settings (filters), as the update could reset them to "Only phone." Can you restore contacts if the phone is broken and not turned on? Yes, if the sync was turned on before the breakdown. Go from your computer to Google Contacts or i.mi.com (for Mi Cloud). All the data that has been synced will be there. You can export them to the new Refard file format later on the phone and transfer them to the reset. If the contacts are not synchronized with the cloud (Google/Mi Cloud) or not saved on SIM-card, recover them after reset is almost impossible without the use of complex paid software for data recovery, and then success is not guaranteed.
