How to make a full screen inbound call on Xiaomi

Owners of Xiaomi, Redmi and POCO smartphones often face the unpleasant situation when an incoming call is blocked by other applications or displayed as a narrow bar on top.This is due to the features of the MIUI or HyperOS shell, where system resolutions can be lost after updates.

To avoid missing important calls from loved ones or colleagues, you need to properly configure the display of the call interface. In this article, we will discuss all possible ways to make an incoming call to the full screen, returning the usual and convenient format of communication.

In some cases, the problem is not with the phone settings, but with third-party applications such as messengers or number detectors, and full-screen call mode is a basic feature that should work flawlessly, and we will help you restore it.

Reasons for the appearance of a small call window

The main reason why a call to Xiaomi appears as a small floating window or a narrow string in a status bar is because the background apps are working.The system tries to optimize the space by thinking that you are busy with another program, such as a browser or a game.

Another factor could be a malfunction of the Phone system application, which may have been reset by default after a major update to MIUI firmware, and third-party number detectors that intercept control of the call interface also have an impact.

Sometimes users accidentally activate Do Not Disturb mode or restrict background activity, which leads to incorrect display of call notifications, and understanding the cause is the first step to solving the problem.

⚠️ Note: If you have multiple calling apps installed (e.g. Google Phone and standard Mi Dialer), the system may be confused as to which interface to use for an incoming call.

Setup of permissions for the phone application

The most effective way to get a full caller's screen back is to check the system permissions, and on Redmi and POCO smartphones, the system app is responsible for this, which sometimes requires manual intervention.

You need to go to the settings and find the partition that manages the applications, and it's important to find the system component, not the shortcut on the desktop. Often users search for "Phone" in the general list, but the menu they want is hidden deeper.

In the menu that opens, find the item associated with displaying on top of other windows, a feature critical to the fact that the call interface can overlap running games or social networks.

• 📱 Open the smartphone settings and go to the Application section.
• 🔍 Select All applications and find the system application "Phone" (green tube icon) in the list).
• 🛡️ Click on Other Permits or Permits.
• ✅ Make sure that the permission to “Display on top of other applications” is enabled».

If this switch is turned off, activating it will instantly solve the problem, and the call will again occupy the entire display, regardless of what you are doing at the moment.

Controlling a floating window during a conversation

There are times when the call has already gone, but it is displayed in a rolled-up form, in which case you do not have to complete the call and wait for the next time. MIUI Allows you to scale the call window manually.

If you see a small window with a talk timer and control buttons, try pressing it. In some versions of the firmware, a double tap or long press turns the interface to the full screen.

And also, look at the corners of the window, and sometimes there's a little bit of arrow or a deployment icon, and if the window is floating, you can drag it to the center of the screen and stretch it with your fingers, like a regular gallery photo.

It's important not to confuse this with hands-free mode. The speaker button changes the sound mode, but doesn't necessarily deploy the interface. Use swipes or navigation buttons to fully control the screen.

💡

If the call window is too small, try turning the phone horizontally – in some design themes, this forcefully deploys the interface to the full screen.

Resetting the call application settings

When simple switches don't help, a deeper approach is required: Resetting the Phone app will bring it back to factory settings, eliminating software errors and configuration conflicts.

This procedure is safe for your contacts and call history, as they are stored in a separate database, but resets can be made to forward or call waiting settings if they were manually set through the phone menu.

Follow the following steps to reset:

• 🗑️ Go to Settings. → Annexes → All applications.
• 📞 Find the phone app and click on it.
• 🧹 At the bottom of the screen, select the Clear (or Delete Data) button).
• ⚙️ In the menu that appears, select “Reset all settings” (not just “Clear cache»).

Then restart your smartphone. When you first call in, the system will recreate the configuration files, and the interface should be displayed correctly.

⚠️ Warning: Make sure you reset the settings of the Phone system app, not the Contacts or Google Phone app, if they are set as additional.

Comparison of system and third-party calls

Xiaomi’s current smartphones can use two types of dialing interfaces: the standard MIUI Dialer and Google Phone, and the differences between them affect how an incoming call will look.

Below is a table to help you determine which app you have active and which features it supports by default.

If you recently installed a third-party call, it could have intercepted the display rights. Check in the settings which application is the default for making calls.

The impact of design themes and lock screen

Xiaomi users like to change their visual style with the Themes app, but poor-quality or outdated themes may contain errors in the call interface code.

If the problem occurs immediately after the change of design, try to go back to the standard theme Classic or Default. Often, third-party theme designers forget to adapt the call screen to new screen resolutions or Android versions.

Also check the lock screen settings. If you have pocket mode or specific gestures enabled, they may interfere with the correct unfolding of the call window. Turn off experimental functions in the lock screen section.

Critical: Some themes change the system files of framework-res.apk, which can cause constant crashes in the work of calls even after returning to the standard, in which case only a complete reset of the phone settings will help.

• 🎨 Open the “Themes” app on your desktop.
• 👤 Go to the user profile (human icon).
• 🔄 Click on Topics and select a standard theme (usually the first one on the list).
• 🔄 Restart the device to apply changes.
