How to make a full screen call on Xiaomi: all the ways for MIUI 14/15

Are you tired of the small window of an incoming call on Xiaomi that sinks among notifications? Or do you want the screen to fully light up when called, like on older button phones? Full-screen call mode is not only more convenient — it reduces the risk of missing an important call due to an accidental swipe. In this article, we will discuss all the working ways to enable the feature on Redmi, Poco and Mi smartphones (including models from 2023-2026), and explain why some devices may not have the option.

The problem is that Xiaomi regularly changes the layout of the settings in new versions of MIUI (especially after the updates to MIUI 14/15). Some full-screen mode is included in two taps, and somewhere it has to be pulled through the developer or third-party applications. We tested all methods on the Redmi Note 12 Pro+, Poco F5 and Xiaomi 13T - and are ready to provide current instructions. Importantly, on some firmware, the feature may conflict with pop-ups or Do Not Disturb mode, we will also talk about this.

1. Standard method through MIUI settings

The most obvious way is to use the built-in options, which works on most devices with MIUI 12-15, but there are nuances for different versions of Android.

Open the Settings app and go along the way:

Settings → Applications → Application Management → Phone → Notifications → Incoming Calls

There should be a Full Screen Mode or Full Screen Mode switch, and if it's not there, your firmware is using an alternative path (see next section). On some devices (like Redmi 10C), the option is hidden deeper:

Settings → Sound and vibration → Incoming calls → Notification style

• 🔍 For MIUI 14/15: The option can be called “Deploy to the full screen” and be in the “Additional” section».
• ⚙️ For POCO Launcher: the path changes to Settings → Special facilities → System settings → Incoming challenges.
• 📱 For Android One (such as Mi) A3): No function in principle – third-party software will be required.

⚠️ Note: Some devices will stop using full screen navigation gestures during a call. To return swipes, turn off the "Block Screen When Called" option in the same settings.

2. Alternative path through “Special Opportunities”

If the standard method didn’t work, try enabling the feature via the accessibility menu, a method that often helps on custom firmware devices or Xiaomi.eu.

Instructions:

1. Find the option “Full-screen notifications” or “Priority notifications”.

On the Poco F4 GT and Redmi K50, this path may look different.

Special features → Additional → Developer settings → Incoming calls → Full-screen mode

Check the version of MIUI (Settings → About the phone)

Turn off the "Do Not Disturb" mode.

Close all background applications

Make a backup of settings (Settings) → Additionally. → Backup)-->

3. Incorporation through Developer Modes

If the option is not in the usual settings, you can “unlock” it through the developer menu, which is suitable for Xiaomi on Android 12+, but requires caution – incorrect changes can lead to crashes.

First, activate the developer mode:

1. Go to Settings. → The phone.
2. Tap 7 times on the MIUI version (you will be notified “You became a developer”).
3. Go back to the main settings menu and open a new section for developers.

Find one of these options (name depends on the model):

• 📞 force_fullscreen_calls — turn on this flag.
• 🔄 Override Force-fullscreen – Select the phone from the list.
• 🛠️ Window animation scale – set the value 0.5x (indirectly affecting the display of calls).

⚠️ Attention: On Xiaomi 12T Pro and Redmi Note 11 Pro+ after-in force_fullscreen_calls The hands-free buttons and the conversation recordings may go missing, so to get them back, reset the developer settings or roll back the changes.

4. Use of third-party applications

If the built-in methods didn't work, third-party utilities will come to the rescue. We tested 5 apps from Google Play - only two were workable and safe. Best option: Full Screen Caller (free, no ads).

Step-by-step:

1. Download Full Screen Caller from Play Market.
2. Launch the app and grant permissions for Notifications and Overlays over other windows.
3. In the application settings, select Full Screen Call Style (recommended MIUI Style for a natural look).
4. Activate the option to Show on top of the screen lock.

Advantages of the method:

• 🎨 Customized background (you can upload your image).
• 🔔 It works even on Android One (where there is no built-in feature).
• 🔕 Support for blacklisting to eliminate spam calls.

💡

If calls are duplicated after installing Full Screen Caller (both standard and full screen windows appear), turn off the phone's built-in notifications in Settings → Apps → Phone → Notifications → Incoming calls.

5. Solving problems with full-screen mode

Even after successful activation, users are plagued by bugs, and here are the most common problems and solutions:

Problem 1: Full-screen mode works, but the screen does not turn on when an incoming call is made.

• 🔋 Check the battery settings. → Battery Optimization – Exclude Phone App from Limitations.
• 🌙 Turn off Dark Theme for calls (sometimes conflicting with animation).
• 🔄 Reboot your phone – on the Redmi Note 10 Pro, it helps 80% of the time.

Problem 2: Call acceptance/reject buttons don’t respond to clicks.

• 🛠️ Include in the developer settings debugging by USB and Don't turn off the screen.
• 📱 Set a standard design theme (castomy themes can break the call interface).
• 🔄 Reset the settings of the Phone application (Settings) → Annexes → Phone. → Warehouse → Drop it).

Problem 3: Full screen only works for contacts from the phone book.

• 📇 Check the settings of the phone → Settings → Spam and Blocking – Disable Unknown Number Filtering.
• 🔍 Make sure that in the settings → Annexes → Phone. → Permissions enabled access to Contacts and Call Log.

💡

If neither method worked, check if your device has global firmware installed (e.g. Xiaomi.eu).In some builds, full-screen calling is disabled at the kernel level and requires manual patching through Magisk.

6. Full-screen calls on a locked screen

A separate story is displaying incoming calls when the phone is locked. Xiaomi only shows a small window by default, but this can be fixed.

Method 1 (without ROOT):

1. Go to Settings → Lock the screen.
2. Select Notifications on the lock screen.
3. Activate Showing notification content and Incoming calls.
4. Turn on the lift to wake up (so that the screen lights up when you call).

Method 2 (c) ROOT-rights):

Install the Lockscreen Customizer module for Magisk and select:

Fullscreen Call → Enable


Wake on Call → Enable




Bypass Lockscreen → Disable (if you need to unlock the screen to respond)

⚠️ Attention: On Poco X5 Pro and Redmi. K60 When you turn on full-screen calls on a locked screen, your fingerprint scanner may stop working during a conversation. MIUI 14.1.2.0 – the solution is only a rollback to the previous version of the firmware.

7. Comparison with other brands: why is it difficult on Xiaomi?

Unlike Samsung or Google Pixel, where full-screen call mode is enabled in two clicks, Xiaomi has traditionally "hidden" this feature. Why?

• 📉 Optimizing the battery: MIUI aggressively saves charge, so by default uses minimalist notifications.
• 🌍 Localization: In China (Xiaomi's main market), full-screen calls are considered intrusive - so the feature is disabled out of the box».
• 🔄 Fragmentation of firmware: The same device (e.g. Redmi Note 11) may have different versions MIUI Global and Chinese markets with different functions.

For comparison, on the Samsung Galaxy, the path looks like this:

Settings → Notifications → Additional → Incoming calls → Full-screen mode

On Google Pixel, the feature is called “Screen Call” and is automatically activated when you first call.

💡

If you frequently call other countries, check out the International Calls settings in the Phone app. On some MIUI firmware, full-screen mode is disabled by default for international numbers (to avoid scaring users with unexpected large windows).
