Owners of Xiaomi smartphones, particularly the popular Redmi 7, often face intrusive mailings, spam messages not only take up space in memory, but can contain malicious links or ads for questionable services, blocking such messages becomes a critical task to preserve peace and security of data.
In this article, we will take a look at all the available ways to protect your device, and we will look at the built-in tools of the MIUI system, which are often hidden from the eyes of the average user, as well as effective third-party solutions, and you will learn to configure filters so that only the really important notifications from banks and delivery services are missed.
There are several layers of protection, from simply locking a specific number to creating complex keyword filtering rules, which will allow you to fully control the incoming flow of information. Below is a detailed description of each method with step-by-step instructions.
Use of the built-in MIUI message filter
The MIUI shell installed on Redmi 7 has powerful built-in tools to combat spam. Many users are unaware of its existence, as it may not be activated or work in soft mode by default. To access the settings, you need to open the standard Messages app and click on the menu icon or three dots in the corner of the screen.
In the list that opens, select Antispam or Antispam Settings, which is where the incoming call and text message control center is located, which allows you to manually blacklist or use automated databases, and it is important to note that some features may require an Internet connection to update spam databases.
Activate the SMS filter switch so that the system can begin to analyze incoming messages, and you can choose the level of filtration rigor, from "Intelligent", which skips most legitimate messages, to "Strict", which blocks anything that looks even slightly spam, and the function of blocking messages from hidden numbers is also available.
💡
Enable notifications about blocked messages in the anti-spam settings to periodically check the folder for false positives and not miss important code from the bank.
⚠️ Note: When you enable a strict filter mode, there is a risk of blocking short numbers from delivery services or two-factor authentication if they are not entered in the database of trusted senders.
After setting up all the settings, remember to save the changes. Xiaomi will start applying the new rules to all incoming messages immediately. Check the blocked message log regularly to adjust the filter settings.
Manual locking of specific numbers
If you're worried about a particular sender, like a former employer or a compulsive store, the easiest way to blacklist their number is to manually, which is the most reliable method, because it doesn't depend on text recognition algorithms, open a dialogue with an unwanted person or find their number in the call log.
Click on the contact information icon or three dots in the top right corner of the screen. In the menu that appears, select the option Block or Add to the blacklist. Once confirmed, the number will be entered into the lock database, and you will not receive any more text messages or calls from it.
The blocked contacts list is managed via the phone menu, where you can view the full list of banned numbers, edit it, or delete contacts if they are again desired, a basic but effective tool for personal security.
- 📱 Open the Phone or Messages app on your Redmi 7.
- ⚙️ Go to the settings and find the “Block” or “Blacklist” section».
- ➕ Click the add button and enter the number manually or select from the history.
- ✅ Confirm the action to permanently close access to this subscriber.
It is worth noting that some carriers use spoofing technology, so spammers can send messages from different numbers, in which case manually locking each new number can become tedious, and it is better to switch to using keyword filters.
Set up a lock by keywords
Spam emails often contain repetitive phrases like “credit,” “winning,” “promotion,” or the names of dubious casinos. MIUI allows you to create your own filtering rules based on those words. It’s one of the most flexible tools available to Xiaomi owners.
To set up, go to the anti-spam menu and find Keywords or Word Filter. Here you can add a list of words that will automatically block the text of the message. The system will ignore the letter register, so the word "CREDIT" and "credit" will be perceived the same.
☑️ Setting up a Keyword Filter
It is recommended to make a list carefully so as not to block important notifications, for example, blocking the word “code” can lead to the fact that you do not receive an SMS confirming your login to a social network or bank, and it is better to use more specific combinations, specific to the spam that you receive.
⚠️ Note: Do not add too short or common words (such as “online” or “service”) to your blocking list, as this will result in the loss of many useful notifications from stores and services.
The effectiveness of this method depends on your attention when compiling a list of stop keywords. Regularly analyze blocked messages and, if necessary, add new keywords that are often found in unwanted mailings.
Third-party applications for spam protection
Redmi 7's built-in tools are good, but sometimes they're not functional enough, especially if spam is coming from international numbers or through special gateway services, and in these cases, specialized applications from Google Play come to the rescue, and they use global databases and artificial intelligence to identify spam.
One of the most popular solutions is the Truecaller or Yandex app, which has a detector and blocker function, and once installed, these apps ask for permission to manage SMS and calls, so that the program can intercept an incoming message, check it on its database and, if necessary, block it even before it appears on your list.
Using third-party software gives you access to advanced statistics and a community of users, and if a number is labeled as spam by other people, your device will know about it instantly, but it's important to keep in mind privacy: when you install these applications, you often consent to the transfer of your contacts to the developer's servers.
- 🛡️ Truecaller is a global leader in caller identification and spam blocking with a huge database.
- 🇷🇺 Yandex – perfectly recognizes Russian numbers and spam mailings, integrates into the system.
- 📉 SMS Blocker is a lightweight application that works according to the rules of regular expressions for advanced users.
- 🔒 Kaspersky Who Calls – a solution from a well-known vendor of antiviruses with a focus on security.
When choosing an app, pay attention to the number of requests for advertising and permissions. Some free versions can be overloaded with their own advertising, which negates the fight against spam. IT-Companies that value reputation.
Blocking Messages from Service Numbers
A separate category is messages from short service numbers, which are often used by mobile operators or partners to block them using standard methods, as numbers can change, but at Redmi 7 level, it is possible to limit messages from service centers.
In the message settings, look for the section associated with “Service Messages” or “Operator Notifications.” You can turn off displaying banner ads and PUSH-This will not block the SMS completely, but will remove visual noise.
To block completely, it is often necessary to send special commands to the operator or connect paid antispam services directly to the provider, for example, many operators have a service that filters spam on the network side without even letting it into the device.
Below is a table with popular operator commands and services that can help in conjunction with phone settings:
| Operator. | Service/Team | Cost | Efficiency |
|---|---|---|---|
| MTS | "Antispam" (*111*383#) | Paid/Free | Tall. |
| Beeline | "Advertising Prohibition" (0674090) | Free of charge. | Medium |
| Megaphone | "Antispam" (880055060) | Paid. | Tall. |
| Tele2 | "Black List" (*144#) | Paid. | Medium |
| Yota | Through my personal office. | Free of charge. | Medium |
Using the operator’s services in conjunction with filters on Xiaomi gives the maximum result. The phone sifts out what the network missed, and the network blocks mass mailings before they reach the network. SIM-map.
Analysis and management of blocked messages
Once you have set up all the filters, it's important to check the Spam or Blocked folder periodically, and sometimes important messages like bank confirmation codes or government notifications get there, and the system is not perfect and can be wrong.
To find these messages, open the message app, click on the menu, and select Locked Messages. This is where all filtered correspondence is stored. If you find an important message, you can extract it by clicking on the corresponding button and add the sender to the whitelist.
What is a whitelist?
Cleaning this folder regularly also frees up your device’s memory, although text text is not very space-consuming, and analyzing the contents of the folder will help you understand which types of spam are most active right now and adjust your keyword list to better fight in the future.
⚠️ Warning: Never click on links from blocked messages, even out of curiosity. Spam messages may contain Trojans that are activated when you click on a link or download an image.
Setting up to automatically delete old blocked messages will help keep order, and in some versions of MIUI you can set a period after which the contents of the spam folder will be deleted irrevocably.
