How to take a full-screen photo of a caller in Xiaomi Redmi: the complete guide

Why a contact photo doesn’t show up on the full screen and how to fix it

Are you tired of the standard fine contact image when an incoming call is made on your Xiaomi Redmi? Do you want a subscriber photo to occupy the entire screen like on commercials? This problem is familiar to many owners of smartphones with a MIUI shell - by default the system only shows a thumbnail at the top of the screen. But there is a solution!

In this article, we’ll look at all the ways you can zoom in on a caller’s photo, including hidden MIUI settings, third-party apps, and even manually editing system files for advanced users, which Redmi models support this feature out of the box, and which require additional customization, and we’ll look at common errors that may not show the photo at all, and we’ll checklist you to fix them.

It’s important to understand that the behavior of the feature depends on the version of the MIUI (12, 13 or 14) and the specific model of the smartphone. For example, on the Redmi Note 10 Pro, the configuration algorithm is different from the Redmi 9A. We collected up-to-date data on all the popular devices in the series and tested each method in practice.

Official method: configuration through standard MIUI parameters

Starting with MIUI 12.5, Xiaomi added the ability to zoom in on a contact photo when you call, but this option is hidden in the back of the menu.

1. Open the phone application (green handset).
2. Click on the three dots in the upper right corner → select Settings.
3. Go to the Incoming Calls section.
4. Activate the full-screen photo of the contact slider (in some versions called Enlarged photo).

If this item is not available, don’t despair! On some models (Redmi 8, Redmi 9C) the option appears only after upgrading to the latest version of MIUI. Check for updates in Settings → About Phone → System Update.

An important nuance: even after activation of this option, the photo will be displayed on the full screen only if:

• 📞 Contact saved in the phone book (not unknown number)
• 🖼️ A photo of at least the size of the contact is attached to the contact 720×720 px
• 🔄 Screen settings disabled Reading or Dark Theme for calls

💡

If the contact photo is blurry on the full screen, try replacing it with an image with a resolution of at least 1080×1080 pixels. MIUI automatically scales low-quality images, leading to artifacts.

Alternative method: use of design themes

If your version of MIUI doesn't have full-screen mode, you can get around the restriction with themes. Many users don't know that Xiaomi themes change not only wallpaper, but also the incoming call interface. Here's how it works:

1. Launch the Themes app (icon with brush).
2. In the search bar, enter a full screen call or full screen call.
3. Select a theme marked Full Screen Caller Photo (e.g., iOS Call Screen or Pure Black Call).
4. Click Apply and confirm the changes.

Popular themes for full-screen display:

Important: Some themes require an internet connection to download additional resources, and if the theme doesn't make your photo full-screen, reboot your phone.

Third-party applications for full-screen display

If none of the previous methods worked, third-party apps will come to the rescue, intercepting incoming calls and displaying their own screens with large photos.

1. Truecaller

A popular call identification app has a built-in full-screen display feature.

1. Open Truecaller Settings → Incoming calls.
2. Enable Full Screen Mode.
3. Choose the display style (we recommend Big Photo).

2. Full Screen Caller ID

Specialized application for Android with MIUI support:

• 🔍 Automatically finds contact photos on social media
• 🎨 10+ call screen styles
• 🔄 It works on top of the standard interface. MIUI

Make sure access to contacts is allowed | Turn off battery optimization for the app | Check compatibility reviews with your Redmi | Make a backup of the phone book-->

⚠️ Note: Using third-party calling apps can increase battery consumption by 5 to 15 percent, and some banking apps block devices with installed call managers due to security risks. Before installing, check if the selected application conflicts with your bank (the list of restrictions is usually on the bank’s website).

Manual setting for advanced users (root required)

If you're ready to experiment and your Xiaomi Redmi has root rights, you can manually edit the system files responsible for displaying calls, which works on 90% of models, but requires caution.

You'll need:

• 📱 Root access (you can get it through Magisk)
• 🛠️ File Manager with support for root (Root Explorer or Root Explorer) FX File Explorer)
• 📄 Backup of the system (required!)

Instructions:

1. Open the file manager and go to /system/priv-app/InCallUI/InCallUI.apk/res/drawable-xxhdpi/ (where xxhdpi may differ depending on the model)
2. Find the files. incall_background.xml and incall_photo_layout.xml.
3. Edit the scaleType setting on centerCrop in both files.
4. Save the changes and restart the phone.

💡

Manual editing of system files can lead to unstable phone operation or even "brick" (breakdown of the software part). Use this method only if you are confident in your actions and have made a full backup.

⚠️ Note: On some models (Redmi Note) 11 Pro+ 5G, Redmi K50) After these changes, the animation of the incoming call may disappear, and to return it, you will have to reset the settings. InCallUI.apk through ADB:

adb shell pm clear com.android.incallui

Problem Solving: Why the photo doesn't show up on the full screen

Even after you set it up properly, you may still see the photo being shown in a small size, and here are the main reasons and ways to fix them:

If none of the methods worked, check:

• 📱 Is the mode for the visually impaired not included in the settings of special features
• 🔒 Are there any restrictions on the phone application in Settings → Annexes → Permits
• 📶 Is there an energy saving mode during the call?

Comparison of methods: which one to choose for your Redmi model

Depending on the Xiaomi Redmi model and the MIUI version, the effectiveness of the methods varies, and we tested all methods on popular devices and compiled a comparative table:

For Redmi models on MIUI 14 (2023-2026), we recommend starting with standard settings – in this version, the full-screen photo function is the most stable. For older devices (Redmi 7, Redmi 6), the only reliable option is third-party apps or manual editing with root.
