Xiaomi smartphone owners often face the need to filter unwanted contacts, whether for intrusive marketing or personal reasons. However, after activating the lock function, many users are lost, not knowing exactly where the system sends these calls and messages. The interface of the MIUI shell and the new HyperOS has its own navigation features that differ from standard Android.
Finding a history of blocked events is not just a matter of curiosity, but an important part of personal safety control. Sometimes important numbers enter this list and need to be quickly unlocked. In this article, we will detail all the ways to access the lock log, including hidden system menus and security application settings.
And you have to consider that the location of the items may vary slightly depending on the firmware version and the regional configuration of the device, but the logic of the system filter remains the same for the entire ecosystem of the brand, so let's figure out where this information is stored and how to manage it.
Use of the Application Security
The main tool for managing traffic and calls in Xiaomi smartphones is the system application “Security”, which is where all the settings of the blacklist and antivirus protection are concentrated. To get to the desired section, you need to open the application with the icon in the form of a shield, which is usually located on the home screen or in the Tools folder.
Once you start the app, scroll down to the Tools block. We're interested in Antispam. When you first log in, the system can request permission to access the call log and messages, which is a requirement for the filter to work properly. If you previously refused access, you will have to manually enable the function in the phone settings.
Inside the Antispam menu, you'll see the general statistics of blocked calls and SMS, and there's a settings button, marked by the gear in the upper right corner, which allows you to flexibly configure filtering rules, for example, block all hidden numbers or calls from other regions.
💡
Check the Antispam folder regularly to make sure that important calls from couriers or doctors don’t get there.
It is important to note that the log in this application keeps a record of not only completely blocked numbers, but also those that were marked as spam by the user or the cloud database MIUI.
Searching for History via Standard Phone
An alternative and often faster way to handle blocked calls is to use the standard Phone app, which in newer versions of the HyperOS shell and current MIUI builds integrates blacklist functionality directly into the dialing interface, so you don't switch between different applications.
Open the call app and look at the three dots in the top right corner of the screen. Clicking on them will open the drop-down menu where you can select Settings or immediately go to the "Blocked" section if it is placed in a separate line. In some firmware versions, this item is hidden inside the general call settings.
The list that opens displays all recent attempts to communicate with blacklisted numbers, and the system usually marks them with a special icon or color so that the user can distinguish them from the usual ones that are missed, and the function of quickly adding a number to exceptions or fully unlocking is available here.
Remember, the log in the Phone app may have a limit on how many records you can see, and if you're looking for an old blocked call made months ago, it may not be there anymore, as the old records are automatically deleted.
Configure the rules of blocking and exclusions
Xiaomi’s flexibility allows you to create complex filtering scenarios, so you can set rules in the lock settings section that will work automatically, such as disabling all calls from numbers not saved in the contact book, or blocking calls at certain times of the day.
Special attention should be paid to the White List function, which, if you add an exception number, calls will take place even when Do Not Disturb mode is activated or spam is strictly filtered, which is critical for emergency numbers or close relatives.
To set the rules, go to Settings → Antispam → Locking Settings. There are switches available for different categories:
- 📞 Block hidden numbers: disables calls from subscribers who hide their ID.
- 🌍 Blocking Foreign Numbers: Useful for Protection Against International Fraud.
- 📞 Block all unknowns: only contacts from the phone book are missed.
What happens to the call when you block it?
Customizing these settings helps to reduce digital noise significantly, but be careful with radical settings such as locking down all unknowns to avoid surviving an important call, such as from a taxi or delivery.
Analysis of the blocked call log
The blocked call log is not just a list of numbers, it's a structured database, and by analyzing it, you can see who tried to contact you when, and it sorts the records by date and time, so you can easily track the chronology of events.
The detailed card of each blocked event often contains additional information: If the number is defined by the MIUI database as spam or telemarketing, it will be marked next to it, and user tags are also stored if you previously marked this number.
For ease of analysis, it is recommended to pay attention to the frequency of calls. If the same number persistently tries to doss dozens of times a day, this can be a sign of automatic call (robot call center), In such cases, it is advisable not just to block, but also to send a complaint to the spam filter database.
| Type of event | Where it's displayed | User action |
|---|---|---|
| Incoming call | Call magazine / Antispam | View, Unblock, Add to the Blacklist |
| SMS message | Spam folder/Antispam | Read, Delete, Restore |
| Hidden number. | Lock log | Ignore or allow (if important) |
Regular audits of this log help keep your phone clean of unnecessary noise, and it also helps you identify new fraud patterns that may be relevant in your area.
Working with messages in the Spam folder
Text messages deserve special attention. Unlike calls, SMS often contain links to phishing sites or fraudulent offers. On Xiaomi smartphones, such messages are automatically moved to a special Spam folder inside the Messages app.
To view content, open the messaging app, click on the menu (three dots or profile icon) and select Spam and lock. This is where all filtered messages are stored. The system uses intelligent algorithms to recognize advertising mailings and malicious links.
It is important to check this folder periodically, as it sometimes contains confirmation codes from banks or services if they were sent from a short number, defined as an advertising one.
☑️ Checking the security of messages
Do not ignore this section, because it is through SMS-messages are often spread by ransomware viruses or links to fake websites of government services and banks.
Third-party applications for extended control
While MIUI’s built-in tools are powerful, some users prefer to install third-party solutions for more subtle control, with apps like Truecaller or Call Blocker offering enhanced spam databases and more flexible lock schedule settings.
When installing these apps, Android will ask for a lot of permissions, and you need to understand that the blocker must have access to all your calls and contacts to work, which creates certain privacy risks, since your contacts can be uploaded to the app developer's cloud.
If you decide to use third-party software, be sure to set it up as the default application for dealing with calls. Otherwise, conflicts between the Xiaomi system filter and the third-party application can lead to the phone ringing twice or, conversely, skipping calls.
⚠️ Warning: When installing third-party number identifiers, be prepared to have your number and your contacts number added to public databases. Use only proven applications with a good reputation.
For most users, the built-in functionality of Xiaomi is quite enough. Third-party solutions make sense only in specific cases when you need to block keywords in SMS or complex routing of calls.
Frequent questions and problem-solving
Even with detailed instructions, users may have specific questions about the operating system, and here we have collected answers to the most popular queries that will help resolve the difficulties.
One of the common problems is when a blocked subscriber hears the beeps, even though he must hear the signal busy. It depends on the carrier and how the lock is done. At the phone level, the call is simply reset, and what the caller hears determines the network.
Why are there no blocked calls in the log?
Can I recover a deleted message from spam?
Does the phone block calls when it is off?
How to unlock the number if the phone is locked?
Understanding how Xiaomi locks allows you to manage your time and nerves effectively, using built-in tools, checking logs regularly, and adjusting filters to your needs to stay in touch with only those you really care about.
💡
The lock log system on Xiaomi is a reliable tool, but it requires periodic manual checks to ensure that important calls are not lost in the spam stream.
