How to make a full-screen incoming call on Xiaomi Redmi 10: detailed instructions

Are you tired of the little incoming call window on your Xiaomi Redmi 10 that is easy to miss on a bright sunny day or while playing? Full-screen call mode not only makes the notification more visible, but also adds convenience to the management — large response/deflection buttons, full-screen contact photo and no distracting interface elements. Unfortunately, in standard MIUI settings, this feature is often hidden or disabled by default.

In this article, we’ll look at all the ways you can activate full-screen mode, from official settings to hidden developer settings. You’ll learn how to configure the display for all contacts or only for favorites, why the feature may not work after a firmware update, and what to do if the call screen remains small despite all efforts. Instructions are relevant for Redmi 10 (including Redmi 10 Prime, Redmi 10C, Redmi 10A) on all versions of MIUI 12–14 and HyperOS.

Why are incoming calls displayed in a small window?

Smartphone makers, including Xiaomi, often optimise the interface for multitasking, with a small call window that allows you to:

• 📱 Continue to use your phone while you call (e.g., watch a map or chat).
• 🔋 Save battery power – full-screen animation consumes more power.
• 🛠️ Simplify integration with features such as Dual Apps or Mode for Kids.

However, for most users, this format is inconvenient, and the reasons why calls can remain in window mode even after settings change are:

• 🔄 Resetting settings to factory (including firmware updates).
• 📴 Conflict with the theme or third-party launchers (for example, Nova Launcher).
• 🔧 Restrictions on Energy Saving or Safe Mode.
• 📱 Activated Mode for One Hand (can affect interface scale).

Method 1: Configure using standard MIUI parameters

The easiest method is to use the built-in options, which is suitable for most users and does not require superuser rights.

1. Open the phone application (pipe icon).
2. Click on the three dots in the upper right corner → select Settings.
3. Go to Incoming Calls (or Call Settings in some versions of MIUI).
4. Find the option Full-screen incoming call (may be called Inbound Call Style → Full-screen).
5. Activate the switch and save the changes.

If Full-screen inbound calls are not on the menu, your firmware version doesn't support them, so go to the developer settings method.

Check the version of MIUI in Settings → About the phone

Make sure your phone is at least 30% charged.

Method 2: Activation through Developer Settings

If the standard method didn't work, try to turn on full-screen mode through hidden settings. This method requires pre-activation of the developer mode:

1. Go to Settings. → The phone.
2. Click 7 times in a row on the line MIUI version (you will be notified "You became a developer!").
3. Return to the main Settings menu → open a new section Additional → For developers.
4. Find the option Full-screen incoming call (or Force full-screen calls in English localization).
5. Turn it on and restart the phone.

Important! In some Xiaomi firmware, this option may be called differently or not.

Settings → Applications → Application Management → Phone → Permissions → Additional permissions → Display on top of other windows (enable)

Method 3: Use ADB-Teams (for advanced users)

If previous methods have failed, you can force full-screen mode to be activated via Android Debug Bridge (ADB), which requires a computer and basic command-line knowledge.

Step 1: Preparation

• 💻 Download and install. ADB Tools on PC.
• 📱 On the phone, turn on the debugging. USB (Settings → For developers).

2. Enter the commands in turn: adb devices (you should see the name of your device – if not, check the drivers).
3. Give permission to debug on the phone screen.
4. Enter the command to enable full screen mode: adb shell settings put global force_fullscreen_calls 1
5. Reboot your phone: adb reboot

If the function did not work after the reboot, try an alternative command:

adb shell settings put global heads_up_notifications_enabled 0

This command disables pop-up notifications, which can force the call window to deploy.

💡

Before using ADB, create a restore point in Settings → Additional → Backup and Reset. This will help roll back changes if something goes wrong.
