How to answer a phone call in Xiaomi Redmi smartphone

Xiaomi’s current smartphones and their sub-brand Redmi offer users a wide range of incoming call management capabilities. The standard interface of the MIUI shell or the newer HyperOS is set up by default for intuitive interaction, but the variety of models and software versions makes their own adjustments. The user may encounter a situation where the usual swipe does not work, or the screen goes out too early, preventing you from taking an important conversation.

Understanding all available methods of answering a call is critical to making the device comfortable in everyday life, not only for basic screen pressing, but also for using hardware buttons, voice commands and special accessories. In this article, we will discuss in detail the mechanics of the call, sensor sensitivity settings and ways to eliminate common failures that can interfere with the connection with the subscriber.

The important thing to note is that some firmware versions of the power saving algorithms can aggressively limit background processes, affecting the interface response rate when an incoming call is made. So if your Redmi Note or Xiaomi Mi is late, the problem may not be physical failure, but software settings.

Basic ways to accept an incoming call

The most obvious and common method of answering a call is to use a touch screen. When the device is unlocked or the screen is just on, the incoming call interface displays a large green handset. To connect, you need to touch the screen in the area of this button or swipe the indicated trajectory if the swipe mode is activated. Depending on the theme installed in the system, the visual display may vary slightly, but the logic remains the same.

If the smartphone is locked and the screen is off, when a call comes in, the display lights up, showing information about the caller. In this scenario, the response mechanics often require the finger to swipe across the screen in a particular direction indicated by the arrow or text prompt. This prevents the phone from accidentally taking the call when it is in your pocket or bag. It is important to move confidently, but without undue pressure, so that the sensor counts the command the first time.

There is also a non-touch screen response, which is especially true in winter or when wearing gloves. Many Xiaomi models support the response function by pressing the side buttons of the sound adjustment. This option can be activated by default or require manual adjustment depending on the version of the Android operating system and the MIUI shell. The use of physical buttons guarantees the acceptance of the call even if the touchscreen malfunctions or the protective glass is of poor quality.

It is worth noting that when connected to a wired headset or Bluetooth headphones, priority is given to the response button on the communication device itself. If the headset is not equipped with control buttons, the response is carried out in a standard way through the smartphone screen or side keys, if this function is supported by a specific communication module and device drivers. In some cases, when connecting to the car Android Auto, the response interface can be duplicated on the multimedia screen of the vehicle.

Setting up the response with volume buttons

The volume button response feature is one of the most popular features among Redmi and Poco smartphone users, allowing you to quickly take a call without looking at the screen, which improves driving safety or ease when working with busy hands.

To enable this option, you need to go to the Phone app, which is the standard system caller, and then open the option menu, usually indicated by three dots or bars in the corner of the screen, and select Settings. In the list of parameters that opens, you need to find the "Respond and End Call" or similar in meaning, and this is where the key switch that activates the side buttons response to incoming signals is located.

It is important to note that some global versions of MIUI firmware may be hidden or missing, and users often resort to installing third-party apps from the Google Play store that emulate system functions and allow them to assign actions to volume buttons.

⚠️ Warning: When activating a response with volume buttons, be careful when removing your smartphone from your pocket.Advertent keystroke may cause an unintentional connection to the last number dialed or contact from the call list.

After activation of the function, testing is recommended. Ask someone to call you and try to answer using only the side keys. If the reaction occurs with a delay or requires repeated pressing, you may need to calibrate the buttons or check for mechanical damage to the body that can block the movement of the keys. In rare cases, a conflict can cause an installed third-party launcher or theme design.

Approximation sensor use and smart functions

The proximity sensor is a small sensor located at the top of the screen, next to the speaker, whose main task is to turn off the screen during a conversation when you hold the phone to your ear to prevent accidental cheek pressing, but this component often causes problems when the screen does not light up when an incoming call or, conversely, goes out immediately after a response, without allowing you to press the on-screen completion or speaker button.

Xiaomi and Redmi have a raise response feature that uses an accelerometer and a gyroscope to detect the movement of the device. If you pick up the phone with it in your hand when the call is made, the system will automatically reset the call or, depending on the settings, accept it. This feature is classified as "Smart Assistants" and is designed to simplify interaction with the gadget. However, its work depends on the correct readings of the motion sensors.

For users who prefer the classic control method, it is important to be aware of the possibility of turning off the "pocket mode."This feature, using the same proximity sensor, blocks random taps when the phone is in your pocket. If the sensor is contaminated or closed with a case, the phone may "think" it is in your pocket and not turn on the screen when you call.

Modern models of the AMOLED-With screens and Always On Display, you can respond differently to incoming calls depending on the battery level. With low charge, the system can restrict sensors to save energy, which leads to delays in displaying the call interface. Therefore, if you experience strange behavior with the screen during calls, the first thing to check the energy saving mode.

Answering the call with accessories and headsets

The use of external devices significantly expands the arsenal of methods of answering calls. Bluetooth headsets, smart watches Mi Band or Amazfit, as well as wired headphones allow you to manage calls without taking your smartphone out of your pocket or bag. The mechanism of work in this case is based on the HFP (Hands-Free Profile) multimedia transmission protocols, which support call acceptance and retraction commands.

When connecting compatible smartwatches or fitness bracelets, the notification of an incoming call is duplicated on the screen of the wearable device. The user can take the call by touching the corresponding icon on the bracelet, and the conversation will go through the smartphone speaker if it is nearby, or through the microphone of the bracelet itself if the model supports voice communication. This is especially convenient when the phone is lying far away or in another room.

Wired headphones with a control button (usually a single multifunction button or separate volume buttons) also allow you to answer calls. Generally, a brief press on the center button answers or ends the call. Long press can reject the call or activate the voice assistant. It is important that the 3.5 mm connector or USB-C/Lightning adapter is fully inserted into the port, otherwise the contact can be unstable and commands will not be transmitted to the smartphone audio controller.

And there are voice assistants, like Google Assistant or Xiao AI (in Chinese firmware), and when you have a headset connected or in hands-free mode, you can voice "Response" or "Accept" to take a call. The accuracy of the command recognition depends on the quality of the microphone and the level of background noise. In a noisy room, voice control may not work properly, so tactile methods remain more reliable.

Solving Call Screen Problems

When a Xiaomi smartphone rings (produces sound or vibrates) but the screen does not light up, it is one of the most frequent complaints of users. This can be caused by a malfunction of the system application Phone or conflict with the established themes. Often the problem is solved by simply cleaning the cache of the application call through the menu of application settings. You need to find the phone list, go to the storage and click Clear cache without fearing losing the call history, since it is stored in the database, not in the cache.

Another common reason is the aggressive operation of the MIUI Optimization energy saving system. The system can “sleep” the phone application, considering it inactive if the call comes after a long downtime. To avoid this, it is recommended to lock the Phone application in memory. To do this, open the list of running applications (multitasking menu), find the call window and pull it down (or press the lock, depending on the version of the interface) to appear the lock icon. This will prevent the system from closing the process.

💡

If the screen doesn't light up when you call, try temporarily turning off Dark Theme or changing the theme to standard. Third-party themes often contain errors in the call interface code that block the display from turning on.

It is also worth checking the notification settings. In some cases, users accidentally prevent notifications from appearing on a locked screen for the Phone app. The way to check is: Settings → Notifications and Status bar → Notifications Management → Phone. Make sure the Lock screen switch is activated and the Show Notifications mode is selected. Without this permission, the system will assume that the user does not want to see the call information when the screen is off.

If software methods don't work, there may be a hardware problem with the light sensor or the screen plume. In such cases, the screen may not turn on because the sensor "thinks" the phone is in the dark or closed. Diagnostics at the service center will help determine whether replacement components are needed. However, in 90% of cases on Redmi and Xiaomi smartphones, the problem is solved by a software reset or system update.

⚠️ Warning: Do not use "deaf" protective glass, completely covering the top of the screen without a cutout under the sensors. This is guaranteed to lead to improper screen operation during a conversation and problems with answering a call.

Set up automatic response and timeouts

For people with disabilities or for use in a car, Xiaomi smartphones have an automatic response feature that allows you to take calls without user intervention after a predetermined time or when you connect the headset. You can find this setting in the special features menu or in the settings of the phone app itself, in the "Autoresponse" section. This is a useful feature, but it should be used with caution, so as not to start a conversation at the wrong time.

There is also the notion of call timeout, the time it takes for a caller to beep before a call is reset by the system or forwarded to voicemail, which is not regulated by smartphone settings but by the carrier level. However, some Android engineering menus (accessible through a set of codes in the call, such as ##4636##) do not recommend changing them without understanding the consequences, as it can disrupt the network.

In the context of automation, you can create scenarios in the Mi Automation app (or third-party analogs) that say, "If you have a Bluetooth car device connected, and the time from 8:00 to 10:00 → turn on the auto-response." This makes the smartphone a full-fledged driver's tool. But remember that automatic response through the speaker can be heard by others if the headset is not connected, so setting volume and Do Not Disturb mode in such scenarios plays a key role.

💡

Automatic response is a powerful tool for road safety, but requires careful adjustment of activation conditions to avoid awkward situations.
