How to make a full screen call on Xiaomi Redmi: from MIUI 12 to MIUI 15

Are you tired of the small incoming call windows on your Xiaomi Redmi that are easy to miss or accidentally swipe? Full-screen call mode not only makes the interface more convenient, but also reduces the risk of missing an important call. However, in recent versions of MIUI, this feature is often hidden or does not work correctly - especially after updates. In this guide, we will discuss all the current ways to enable full-screen mode, including hidden settings, bug bypass and alternative solutions for models from Redmi Note 10 to Redmi 13C.

Compounding the problem, Xiaomi regularly changes menu options, and some features are regionally dependent. We tested all methods on MIUI 12.5-15 firmware (including global and Chinese versions) and highlighted those that work consistently. If standard settings don't help, we have backup options using ADB and third-party apps.

1. Standard way through phone settings

On most Xiaomi Redmi devices, full-screen call mode is enabled via the phone's settings menu, but the path to this option varies depending on the MIUI version and model.

1. Open the Settings app (cog icon).
2. Go to the Appendix section → Application management.
3. In the search bar, enter the Phone and select the system application Phone (not to be confused with Contacts).
4. Slip on permission → Additional → Display on top of other windows.
5. Activate the Allow display switch on top of other applications.
6. Go back to the basic settings of the Phone application and find Inbound Calls or Call Interface.
7. Select Full-screen mode (or Extended view in some firmware).

If you don't have Full-screen mode, your firmware doesn't support it directly, so you can move on to the following methods. On some models (e.g. Redmi Note 11 Pro+), this option only appears after you reset the phone app settings:

Be sure to export your contacts to Google account | Remember your call forwarding settings |Take screenshots of important parameters (e.g. blacklist) |Take a backup of your SMS (if necessary)

-->

Attention! After resetting the app settings, the phone may get lost:

• 📞 Call forwarding settings
• 🔕 Number lock lists
• 📱 Individual Melodies for Contacts

2. Alternative method through "Special Opportunities"

If the standard path didn't work, try to turn on full-screen mode through the special features settings, which works even on Redmi with customized firmware:

1. Open the Settings. → Special facilities.
2. Go to Notifications and Status Panel.
3. Find Full-screen notifications (or Advanced notifications).
4. Activate the option for the phone application.

On some devices (e.g. Redmi K50), this option is called Priority Notifications, and once activated, all incoming calls will be displayed on top of any open applications, including games and videos.

💡

If you turn on this option, if you still see calls in a small window, try restarting your phone, and sometimes you only change them after you reboot.

3. Use of ADB for forced inclusion (advanced method)

If none of the previous methods worked, you can force full-screen mode to be enabled via ADB (Android Debug Bridge), a method that requires connecting the phone to a computer and works on all versions of MIUI, but is not recommended for beginners - the wrong commands can disrupt the system.

You'll need:

• 🖥️ A computer with installed Xiaomi drivers and ADB
• 📱 Included debugging by USB on the phone (Settings) → The phone. → Version. MIUI → 7 times to tap according to the version → return to → For developers → Debugging by USB)
• 🔌 USB-cable (preferably original)

Instructions:

1. Connect the phone to your computer and allow debugging over USB.
2. Open the command line (cmd) and enter:

adb shell settings put global heads_up_notifications_enabled 1


adb shell settings put global policy_control immersive.full=com.android.server.telecom

After you execute the commands, restart your phone. If the full screen mode is not working, try the additional command:

adb shell am start -n com.android.settings/.Settings$DisplaySettings

WARNING! Using ADB can lead to:

• 🚨 Failures in system applications
• 🔄 Need to reset settings
• 🛡️ Loss of warranty (if phone warranty)

4. Third-party applications for full-screen calls

If system methods don't work, you can use third-party apps from Google Play, which intercept incoming calls and display them in full screen mode.

Before installing, check the app permissions — some request access to SMS, Contacts, and Call Log. Xiaomi is particularly interested in:

• 🔒 Allow auto-start (Settings) → Annexes → Autostart control)
• 📱 Enable display over other windows
• 🔔 Give access to call notifications

5. Solving problems with full-screen mode

Even after successful full-screen inclusion, Xiaomi Redmi users often encounter bugs, and here are the most common problems and solutions:

Problem 1: Calls are displayed in full screen mode, but without photo contact

Reason: No sync with Google Contacts or display settings are lost.

Decision:

1. Open Contacts → Settings → Display Contacts.
2. Choose Google as your primary account.
3. Reboot the phone.

Problem 2: Full-screen mode only works for some contacts

Reason: MIUI has a separate setting for "Favorites" contacts.

Solution: Check:

• 📇 In the call log, click on the contact. → Edit → add to the Favorites.
• 🔄 In the Phone app settings, disable the Features Only option (if any).

Problem 3: After the MIUI update, the full-screen mode is gone

The reason: Xiaomi often resets custom settings after major updates.

Solution: Repeat the steps from the first section or use ADB (Section 3). If it doesn't work, wait for the patch (usually comes out 1-2 weeks after the major update).

💡

After updating MIUI, always check the settings of the Phone application - they are reset the most often.

6. Full-screen mode on Redmi with customized firmware

If you use informal firmware (like LineageOS, Pixel Experience or Xiaomi.eu), standard methods may not work.

1. Check for the Full Screen Call module in Magisk (if you have root).
2. Install Substratum or LSPosed with a theme that supports full-screen calls.
3. Edit the build.prop file (power users only!) by adding a line: ro.telephony.call_ring.delay=0

On Xiaomi.eu firmware, full-screen mode is usually enabled through:

Settings → MIUI settings → Additional → Full-screen notifications

Attention, custom firmware.

• ⚠️ Full-screen mode may conflict with Magisk modules.
• ⚠️ Some topics break the call interface.
• ⚠️ After updating the firmware settings are reset.

7. Comparison of methods: which one to choose?

Depending on your Redmi model and the MIUI version, the effectiveness of the methods varies.

For most users, the best course of action is:

1. Try the standard settings.
2. If it doesn’t work, use special opportunities.
3. For advanced users, ADB is the standard.
4. If nothing helps, third-party apps.
