How to change the call answer button on Xiaomi smartphone

Android users often face the need to personalize their device’s interface, making it not only convenient but also unique. The question of how to change the call button on Xiaomi smartphones is a common one, especially after upgrading or switching from a different phone brand. The standard call interface can seem boring and in some cases not functional enough for people with visual impairment or specific needs.

Unlike many other manufacturers, Xiaomi’s MIUI shells and new HyperOS offer a lot of customization options, but they are often hidden in non-obvious menu sections. You probably won’t find a direct “change color slider” setting on the standard menu. However, there are several proven methods to completely transform the look of an incoming call.

In this article, we’ll take a look at all the ways you can use themes, to third-party apps and system modifications, and learn how to make a button more visible, change its shape, or even replace the standard slider with large call acceptance and drop buttons. This guide is relevant to most modern models, including the Redmi Note series, Xiaomi Mi and POCO.

Standard settings of the interface of calls in MIUI and HyperOS

The first thing to do before looking for complex solutions is to carefully study the standard features of your shell version. In the latest updates to MIUI 14 and HyperOS, developers have added some useful options that allow you to change the behavior of the interface during an incoming call, these settings are in a section that many users often ignore, considering it too simple.

To access the basic settings, open the Phone app and click on the three dots at the top of the screen. In the drop-down menu, select Settings. Here you are interested in a section that may be called Inbound Calls or Interface, and that's where the key switches that affect how the lock screen looks when you call are hidden.

• 📱 Display style: In some versions of the firmware, the option to switch between the full screen and the window on top of other applications is available.
• 🔊 Vibration and sound: adjusting the device’s response to an incoming call that indirectly affects the perception of the response button.
• 📞 Quick Answers: The ability to customize text messages that are sent when you refuse a call.

It’s worth noting that standard settings are limited to regional firmware features, such as the Global ROM, which may have fewer options than the China ROM. If you don’t find the right switch, your version of the software may not support this feature out of the box and you’ll need to use themes.

💡

If standard settings don't work, don't rush to drop your phone, and 90 percent of the time, the problem is solved by changing the theme of the design, not flashing the device.

Using the Themes app to change design

The most effective and safest way to change the appearance of the answer button is to use the built-in Themes app. Xiaomi Theme Store contains thousands of designs that change not only icons, but also system screens, including the lock screen and the call interface.

To get started, open the Themes app (a colorful diamond icon). In the search bar, type in keywords like "Call," "Dialer," "Incoming," or "Call." In the search results, pay attention to the preview: many theme writers specifically demonstrate what the incoming call screen will look like. Choose your favorite design and click "Download."

⚠️ Note: Some topics may be paid or require you to view ads to activate. Also be careful with topics from unknown authors, as they may contain advertising modules.

After you load the theme, make sure to apply it. Click on Apply and select the Lock Style or System component if the theme is complex. After you apply the theme, the lock screen and the response button will change their appearance. If the result does not suit you, the topic can be easily deleted through the “Profile” menu» → «Topics».

Instructions for installing third-party calls

If the built-in features and themes don't meet your requirements, you can go a radical way - replace the standard Phone application with a third-party counterpart, this solution allows you to completely change the logic of how calls work, add recording of conversations, determine the number and, of course, the unique design of the response button.

One of the most popular and functional solutions is the Truecaller or Simple Dialer app, which, once installed, will require permission for Android to use as the primary call app, and you have to agree to that, otherwise the new interface will not show up when you call in.

In the settings of a third-party application, there is usually a section called “Look” or “Theme” where you can choose the color of the button, its transparency, the animation of the appearance and even the background image. Some applications allow you to create your own profiles for different contacts, changing the style of the button depending on who is calling.

Set up large buttons for the visually impaired

The issue of accessibility deserves special attention. For older people or visually impaired users, the standard sliding button can be uncomfortable. Android and MIUI have special modes that replace the slider with two large, clearly separated buttons: Accept and Reject.

To activate this mode, go to Settings → Advanced Settings → Special Options. Find a section related to physical interaction or hearing. In some versions of MIUI, this option is hidden in the Visibility Improvement or Increase menu. Activating the Large Response Buttons switch will instantly change the interface.

Using these features not only makes it easier to interact with your smartphone, but also reduces the likelihood of an accidental reset of an important call, which is especially true in situations where the phone is in your pocket or bag and you need to react quickly.

Problems with displaying the button after updates

Often users notice that after updating the system, the response button becomes transparent, shifts to the side or disappears altogether behind the edge of the screen, a common MIUI bug that involves a conflict of the system interface cache or an incorrectly applied theme, and you can solve this problem without losing data.

The first step is to clear the theme and system interface cache. Go to Settings → Apps → All apps. Go to Topics list, click Clear Cache → Repeat the same for System Interface (may be called MIUI System).

If cleaning the cache didn't work, try resetting the theme to the standard one. Go to the Themes app, go to the profile, and select the standard Classic or Default theme. Using a standard theme often cures graphical glitches, returning the answer button to its original position and functionality.

⚠️ Note: Do not remove the System Application "Themes" through ADB This can cause the call interface to stop showing at all and you won't be able to accept calls.
