Why are there no contacts in the phone Xiaomi Redmi 9T

Owners of the smartphone Xiaomi Redmi 9T Sometimes you're faced with a very unpleasant situation where the new subscriber number just doesn't get written into the device's memory, so you type in numbers, you press the save button, but the system either silently ignores the action, or it gives an error, or the contact disappears immediately after the window closes. This problem can be caused by many factors: from the banal lack of space on the SIM-Map of complex conflicts in the work of Google cloud services.

Ignoring this symptom is dangerous, as losing important phone numbers can lead to serious communication failures at the most inopportune time. In most cases, the failure lies in the wrong default storage or software conflict of the MIUI shell. Below we will discuss all possible causes and propose a step-by-step algorithm for correcting the malfunction.

Analysis of the selected data storage location

The first thing to look out for when an error occurs is the target storage. In modern Xiaomi smartphones, the default is often synchronization with a Google account, but if the Internet connection fails or the cloud overflows, the system can block the recording. If you are trying to keep the number on SIM-card, the problem may be in its physical wear or limited memory capacity.

Check your display and save settings in the Contacts app. Often users don't notice that they have a filter activated to hide certain groups or that they have a read-only storage option.

The key is understanding the differences between local storage and cloud storage: The phone's local memory is faster but requires regular backups, whereas a Google account provides data security when a device is lost, but depends on network stability.

⚠️ Note: If you keep your contacts exclusively on SIM-card, remember that in case of breakage or loss of the card, it will be almost impossible to restore the numbers without special readers.

It is recommended to forcefully change the save location to “Phone” or “Google” when adding a new subscriber to exclude errors of the carrier.

Synchronization and Google account issues

One of the most common reasons Redmi 9T stops maintaining contacts is because it is not synchronized with Google servers, which can happen after changing the password, updating the terms of use or when the allocated space of 15 GB is overflowed.

To diagnose, you have to go to your system settings and check the synchronization status, and if you see an error icon or a constant rotation of the boot indicator, you have a data exchange that is locked, and in some cases, simple re-authorization in the system helps.

• 📱 Go to Settings. → Accounts and synchronization in the device menu.
• 🔄 Select your Google account and click on Sync».
• ❌ If the “Contacts” tick is ticked, remove it, wait 10 seconds and put it back.

It’s also worth checking whether traffic savings or Do Not Disturb mode are included, which may limit background activity on Google Play services, and turning these restrictions off often returns functionality to the phone book.

Overflow of memory and cache of the application

Accumulated software debris often causes system applications, including the phone book, to malfunction. If the Contacts or Phone app cache is overflowing or corrupted, new records cannot be processed and stored in the SQLite database.

Cache cleanup is a safe operation that won’t delete your saved numbers but will reset temporary files that may have caused conflict, a procedure that is especially relevant for devices that are in use for long periods of time without rebooting or resetting settings.

Follow the following steps to clean up:

1. Open Settings → Applications → All applications.
2. Find in the list “Contacts” and “Phone”.
3. Click on “Storage” and select “Clear Cache”.

If a simple cache cleanup didn’t help, you can try to clear the application data, but only after you have created a backup, as this action will return the application to factory status and can delete locally stored numbers.

Third-party application conflicts and access rights

Installing third-party calls or messengers (e.g. Truecaller, GetContact) can take over the management of the phone book. Such applications often require advanced access rights and block the standard save function when versions conflict or bugs in the code.

Check the list of installed applications that have access to contacts. If you recently installed new software to determine the number, try temporarily removing it or revoking access rights.

It’s also worth making sure that the standard Contacts app has all the necessary permissions, and in MIUI, this is controlled through the Permissions menu, where you can manually enable access to memory and telephony.

Failures in operation SIM-map

Physical condition SIM-The cards play an important role, especially if you are trying to save a number on it.The contacts of older SIM cards have a limited amount of memory (usually 250 entries) and an outdated file system that can conflict with modern versions of Android on Redmi. 9T.

If the card has been cut by hand or has been damaged on the contacts, the phone can read it with errors, in which case the system will prohibit the recording of new data to avoid losing existing ones.

Try to get it out. SIM-If the problem persists, the only solution is to replace the contacts with a soft cloth. SIM-card with the operator with the preservation of the number.

⚠️ Please note: Do not try to keep more than 200 contacts on your website. SIM-card, even if the phone allows it - this can lead to the complete loss of the phone book when changing the device.

System Update and Program Errors

The MIUI operating system installed on the Xiaomi Redmi 9T receives periodic updates that may contain bug fixes, but sometimes newer firmware versions themselves become a source of bugs, especially if the update was incorrect or interrupted.

Check for updates in the Settings → About Phone menu. If you have a firmware beta installed, the probability of software failures is much higher, in such cases, it is recommended to roll back to the stable version or wait for the official patch.

If the problem appears immediately after the update, resetting the phone’s app settings via the Recovery menu or a full device reset will help, but this is an extreme measure.

💡

Before installing major MIUI updates, always back up your contacts via Mi Cloud or Google to avoid losing data in the event of a crash.

Cardinal measures: Resetting and flashing

When none of the software methods work, you have to perform a full reset (Hard Reset), which will remove all data from the phone, returning it to the state of "out of the box", which is guaranteed to eliminate any software conflicts that interfere with the operation of the phone book.

Before starting the procedure, be sure to back up all important data. Reset can be done through the settings menu or using a combination of buttons when the phone is turned off.

Settings → About the phone → Reset settings → Erase all data

If even after the reset the problem persists, it is possible that the system partition of memory is damaged or there is a hardware malfunction of the motherboard, which requires contacting the service center.
