Xiaomi’s smartphones, which run MIUI shells or the new HyperOS, offer users advanced telephony management functionality. Call rejection is a basic but critical feature that can be required in a variety of situations, from a business meeting to a movie theater. The standard method of using screen buttons is familiar to everyone, but the Android system provides much more flexible tools for dealing with incoming calls.
Owners of Redmi and Poco devices often do not even realize that they can set up an automatic response with a text message or use a proximity sensor to instantly reset a call without touching the screen. The flexibility of settings allows you to adapt the behavior of the phone to specific use cases, ensuring a balance between availability and personal space. In this article, we will discuss in detail all known ways to block incoming connections.
We're going to look at not just the standard actions, but the hidden features that are often beyond the reach of ordinary users. Understanding how Android's interrupt system works will help you manage your time effectively and keep really important calls from being missed by weeding out spam or unwanted communication. Let's dive into the technical details.
Standard methods of rejecting a call
The most obvious and common way to complete an incoming connection is to use the call screen interface. When the device is unlocked and the screen is active, the user sees two main buttons: green for response and red for off. Pressing a red handset immediately breaks the connection, and the caller hears short beeps or a message about the unavailability of the subscriber.
This changes when the smartphone is locked, and the incoming call interface is lit up on the screen, overriding all other notifications. To reject a call on a locked Xiaomi, you need to swipe the red button in the specified direction (usually left or up, depending on the version of the theme), this action requires a certain accuracy, especially if the phone is on a flat surface.
There's also a universal method that works on most models, regardless of the firmware version. If you need to quickly reset a call without looking at the screen, you can double-press the power switch on/off, which is the default feature activated on the system and allows you to ignore the call with one confident thumb movement.
Using the power button for quick reset
The power button disable call is one of the most convenient, but often requires pre-checking settings. In MIUI and HyperOS shells, this option is usually turned on by default, but in some custom builds or after a system update, it can be deactivated. To make sure your Xiaomi smartphone responds to double tap, you need to go to the appropriate settings menu.
To check and activate the function, go to Settings, then select Additional (or Advanced Settings). In the list that opens, find the Special Opportunities category or immediately look for the Power Button. This is where the "Finish Power Button Call" switch hides. If the switch is active, double pressing the side key will instantly reset the incoming call.
This is especially useful in winter when you're wearing gloves, or when the phone is down, so you don't have to look for a touch button, you just have to feel the physical control on the body, and it gives you tactile control over the device, which greatly speeds up the response to the input signal.
💡
If double-pressing doesn’t work, check if Do Not Disturb mode is enabled, as it can change interrupt priority and button behavior during a call.
It's worth noting that the sensitivity to double-pressing can vary depending on the processor model and the driver version. On some older Redmi models, the interval between taps should be very short, almost simultaneous. If you can't reset the call the first time, try changing the rhythm of the taps.
Set up a response message when rejecting
One of the most underrated features in Android is the ability to automatically send. SMS-This allows you to politely tell the caller why you can't answer without interrupting the current session for voice conversation, and it offers a set of standard phrases, and it also allows you to create your own templates.
To activate this option, open the standard Phone app (green handset icon). Click on the three dots in the upper right corner of the menu and select Settings. Next, go to the Answer section with a message (or Quick Answers). Here you will see a list of preset texts that can be edited to your needs.
You can replace the standard "I'll call you back later" with a more specific one: "I'm in a meeting, I'll be free in an hour" or "Driving, I'll dial in the parking lot." When you reject the call, a pop-up will appear on the screen asking you to send one of these messages, just select the option you want.
☑️ Set up quick answers
Using automatic responses is especially important for business people and freelancers who need to maintain a professional image, and the caller sees that their call is not ignored by chance, but deliberately rejected with explanation, which reduces anxiety and prevents a series of repeated calls in an attempt to reach you.
Gestures and control without touching the screen
Today’s Xiaomi smartphones are equipped with a variety of sensors that allow you to control the device without direct contact with the display. One of the most effective ways to deflect a call is to turn the phone down with a screen called “Flip for silence” or “Gestural”, and it not only mutes the sound of the call, but can automatically reset the connection.
To adjust this behavior, go to Settings -> Additional -> Gestures. In this section, you should find the option "Flip to silence" or "Switch off sound when flipping." In some versions of MIUI, there is a separate switch "Deflect call when flipping." Activating this feature allows you to instantly respond to a call in the theater or library by simply putting the phone on the table.
If the interface settings have the appropriate option enabled, swiping the screen in a particular direction (e.g., bottom up or sideways) can perform a knock-off action. However, be careful: accidentally swiping in your pocket or bag can cause an unplanned reset of an important call.
⚠️ Warning: The phone's flipping function to deflect a call may not work properly if the device has a thick protective case or uses a magnetic mount in the car.
Using gestures makes it more intuitive to interact with MIUI, so you don't have to look for a button on the screen, you just have to change the physical position of the device in space, and this is especially convenient when your hands are busy or dirty.
Blocking Unwanted Numbers and Spam
If you have a question about how to reject a call regularly, the best solution is not to manually reset, but to completely block the contact. The antivirus and security module built into the MIUI shell allow you to create blacklists that automatically reset calls from certain subscribers or all hidden numbers.
To add a number to the blacklist, open the Security app (lightning icon or shield) and select the Antispam section, where you can set the lock to various criteria: block all hidden numbers, block numbers from other countries or add a specific contact to the list of prohibited ones. Once added, the caller will hear the beeps, and on your screen will not even pop up the notification of the call.
There's also a Quiet Mode for Unknown Numbers feature, which, if activated, will automatically deflect calls from numbers that aren't in your phone book or be turned into vibration mode without audio accompaniment, ideal for those who want to be accessible only to friends and colleagues.
| Type of lockdown | Where to find out. | Result for the caller | Notification on Xiaomi |
|---|---|---|---|
| Manual discharge | Eran the call | Hooks are "busy." | Missed challenge |
| Blacklist | Antispam / Security | Blower or discharge | No (hidden) |
| Do Not Disturb mode | Notification curtain | guguda | No (quiet mode) |
| Blocking of unknowns | Phone settings | Reset | No. |

Do Not Disturb and Automation
For situations where you need to completely cut off the outside world, Xiaomi has a Do Not Disturb mode. Unlike simple locking, this mode allows you to create flexible rules. You can configure it so that calls from favorite contacts pass, and everyone else automatically declines.
You can activate mode through the notification curtain or in Settings -> Sound and vibration -> Do not disturb. Here you can set a schedule (for example, from 23:00 to 07:00) or turn on a repeat call. The function "Repeat call" works on the principle that if the same number calls twice in 15 minutes, the second call will pass, because the system considers this as an emergency.
Using automation through scripts allows you to expand the possibilities even further, for example, you can create a scenario: "If you have a Bluetooth earphone connected -> Enable Do Not Disturb mode," so if you take your phone out of your pocket during training, you won't hear a call, because it will be automatically rejected by the system.
⚠️ Warning: Do Not Disturb mode will usually keep alarms running, but make sure that the exception settings do not tick the alarm clock if you want complete silence.
Solving Challenge Deflection Problems
Sometimes users are faced with a situation where standard methods stop working: the power button does not reset the call, or the screen does not respond to touch, most often due to a software failure of the Phone application or a conflict of design themes. The first step should always be to restart the device, which cleans the RAM and restarts system services.
If the problem persists, check the permissions for the Phone app. Go to Settings -> Apps -> All Apps -> Phone -> Permissions. Make sure the app is allowed to display over other windows and use the microphone. Lack of necessary permissions can block the call management functionality.
In rare cases, the cause may be a faulty touchscreen or proximity sensor. If the screen is "glutching" during the call, try to remove the protective glass or film, as they can cause interference. It is also worth upgrading to the latest version of HyperOS or MIUI, as developers regularly release patches that fix interface bugs.
💡
If none of the software methods help to deflect a call, try pressing the volume button – on some Xiaomi models, it’s an alternative way to reset a call that doesn’t require tuning.
