The modern rhythm of life dictates its rules, and the phone often turns from a means of communication into a source of constant stress. Endless calls from advertising agencies, intrusive bank employees and unknown numbers can unbalance anyone. This problem is especially acute when you need to focus on work or relax with your family, and Xiaomi persistently vibrates in your pocket. Fortunately, the shell of MIUI and the new HyperOS has powerful filtering tools that allow you to take control of the situation in your own hands.
The key is to make sure you're properly configured to do not disturb, not just a quiet mode, but a full-fledged filter that can ignore all calls except those from people in your notebook, which makes your smartphone a reliable guardian of your personal space, and in this article, we'll take a look at how to activate this feature, what are the nuances in different versions of the firmware, and how to avoid common errors.
Ignoring unknown numbers is not just a matter of comfort, it's also a matter of digital hygiene. Attackers and scammers often use numbers that aren't in spam filter databases, but are not exactly on your friend list. By limiting your trusteeship, you automatically increase the security of your data and your finances. Let's move on to the practical implementation of this useful feature.
Preparation of a list of trusted contacts
Before you turn on strict filters, you need to make sure that all the numbers that are important to you are actually stored in the device memory or synced with your account.If you miss this step, there is a risk of losing contact with the courier, doctor or colleague whose number you just forgot to write down. Open the standard Contacts or Phone app and check the list carefully.
There's a concept of Starred in the Xiaomi and Android ecosystems, and it's the fastest way to create a whitelist, just put an asterisk next to the names of those who have to call at all times, even in the most severe hours of silence, and it's a versatile method that works more consistently than manually creating groups.
Also check if important numbers are lost in the Hidden Contacts section or on the SIM-If the sync is not working correctly, it is better to have all key numbers duplicated in a Google or Mi Account cloud account for reliable filtering. This ensures that even when you reset or change your phone, your trusted list will not be lost and the filter will continue to work properly.
- 📞 Open the Contacts app and find the Favorites section».
- ⭐ Add an asterisk to the numbers of family and close colleagues.
- ☁️ Make sure you have a sync checkmark with your Google account.
- 🔍 Check if important numbers are blocked accidentally before.
☑️ Check before setting up the filter
Setting up the “Do Not Disturb” mode on Xiaomi
The main tool for this task is the Do Not Disturb (DND) system function. Unlike a simple silent mode, it allows you to flexibly adjust the rules for skipping calls. To get to the desired menu, go to your smartphone Settings. The interface may vary slightly depending on the version of MIUI, but the logic remains the same.
In the settings menu, look for the Sound and Vibration section, and that's where all the options associated with the audio notifications are hidden. Find the Do Not Disturb and click on it. You'll see a control panel where you can schedule or activate the mode manually. First, we'll need to get into the advanced settings, which are often hidden in the submenus or marked with a gear.
Inside the mode settings, find the "Calls" or "Allow Calls" section. The default is "All" or "Nobody." We need to change this setting. Choose "Contacts Only" or "Favorites" if you want maximum rigor. The system will warn you that calls from other subscribers will not be coming to the phone, but will simply be reset or blocked.
⚠️ Warning: When you activate Do Not Disturb mode with the contact filter, the caller will hear short beeps, and then a message that the subscriber is unavailable.
It's important to understand the difference between ignoring completely and skipping repeat calls. DND settings often have a "Repeat Calls" option. If you activate it, a call from an unknown number that is made a second time in 3-5 minutes will still pass, and it's insurance for an emergency when someone needs to reach you urgently.
Use of the “Block” function to strengthen protection
Xiaomi and Redmi have a separate, more aggressive tool, the Security app, which has its own locking module that works independently of system DND and often works better with spam. Open the Security app, which has a lightning shield icon, and find the Lock section.
Here, you click on the settings gear in the top right corner, and we're interested in the "Lock Rules" section, which is where you can adjust your phone's behavior when you call in, select "Lock Calls," and activate the "Block Calls from Unknown Numbers" switch, which works at the system level and sifts out calls before they even try to wake up the phone.
The advantage of this method is that it doesn't require Do Not Disturb mode. You can listen to music, play games, or watch audio videos, and the phone won't interrupt the process with calls from advertising numbers. However, beware: some delivery services or taxis may call from hidden or temporary numbers that the system will consider unknown.
What is the difference between DND and Blocking?
If you use both methods at the same time, priority is usually given to a stricter rule: it is recommended to set “Block” as a permanent background shield, and “Do not disturb” mode to turn on on a schedule (for example, at night) for complete isolation, allowing only a select few to pass.
Comparison of call filtering methods
To make it easier for you to choose the right option to protect against unwanted calls, we have prepared a comparison table that will help you understand which method is best suited for your current tasks: whether you need complete silence or just spam protection during the day.
| Parameter | Do Not Disturb mode | Blocking of unknowns | Blacklist (manually) |
|---|---|---|---|
| Principle of action | Hiding notifications and sound | Automatic call reset | Blocking specific numbers |
| Impact on contacts | You can set up a pass for selected | It only misses from a notebook. | Blocks only selected numbers |
| Convenience | Included on schedule | Works all the time. | Requires manual addition |
| Effectiveness against spam | Medium (call fixed) | High (the call won't pass) | Low (spam changes numbers) |
As you can see from the table, a combination of methods is best for the task of "letting calls only from the notebook": Do not disturb mode gives flexibility in time management, and the lock function in the security application provides constant protection.
And don't forget third-party apps like Yandex or GetContact. They can complement system tools using cloud-based spam numbers. However, Xiaomi's built-in tools are enough to solve a specific problem of filtration by contacts, and they work more stable without using battery power in the background.
Scheduling and automation
Manually turning on and off protection modes can get boring. Fortunately, automation in MIUI and HyperOS works perfectly. Go back to the Do Not Disturb settings and find the option "Schedule" or "Switch on automatically." Here you can set time intervals, for example, from 23:00 to 07:00, when the phone will go into silent mode.
A more advanced option is to use automation scenarios, where you can create a rule in the Security app or Google Assistant, "If I'm in the Work location, turn on the Selected Only mode." This requires you to set up the geofences initially, but then it runs completely autonomously, and the smartphone will know that you're in the office and cut off any extra calls.
Also worth considering is the “While Driving” scenario. In Settings → Connection and Sharing → Driver mode, you can set up an automatic response or lock notifications while the phone is connected to the car’s Bluetooth.
⚠️ Warning: When setting up automatic scripts, always leave emergency interruption options. Make sure that Re-Call is activated so that loved ones can reach you even in automatic mode in case of real danger.
Automation allows you to forget about the constant control of settings.once you will set the rules, the system will work like a clock, this is especially true for people with irregular schedules, who need to quickly switch between “available” and “unavailable” modes.
Solution and troubleshooting
Even with the right setup, there can be situations where the desired effect is not achieved. Often users complain that the phone still rings. The first reason is messenger apps. Android's "Do Not Disturb" settings are default for regular phone calls (GSM), but can ignore calls via WhatsApp, Telegram or Viber.
To fix this, you need to go to the settings of each messenger separately. Telegram, for example, has its own Do Not Disturb mode, which you need to activate and configure there. WhatsApp notification settings are also independent. This is a common mistake that many Xiaomi owners forget about.
Another problem is that the alarm clock is running. The default alarm should go off even in Do Not Disturb mode, but if you have a third-party call or alarm program installed, it can be blocked by the power saving system. Check the battery settings for important applications and make sure that there is a "No Limits" limit for them.
💡
If the filter is set up and calls still pass, check to see if the phone is activated with Pocket mode, which can block the screen, but does not always filter incoming calls according to your new rules.
It’s also worth checking for system updates. Older versions of MIUI may have bugs that reset filtering settings after rebooting, and updating to the current firmware version often resolves such software conflicts.
