How to Put a Big Picture on the Full Screen When Calling Xiaomi: The Complete Guide

Owners of smartphones Xiaomi, Redmi and POCO Often, they are faced with the fact that the photo of the contact when the incoming call is displayed too fine or cropped. MIUI They don't always allow you to stretch the image to the full screen, especially on models with cutouts for the front camera or dynamic islands. MIUI 12 to MIUI 15, and on some devices (for example, Xiaomi 13 Pro or Redmi Note 12) the trim algorithm works differently than on budget models.

Meanwhile, a large photo on a call not only improves visual perception, but also makes it easier to identify the caller - especially important for users with vision problems or those who often use the phone in motion. In this article, we will analyze all the available ways to stretch a photo to the full screen: from standard settings. MIUI Before using third-party apps and hidden engineering menu features, you’ll also learn which image formats are best for this purpose and how to avoid common customization errors.

If you have tried to change the size of the photo through Contacts → Edit → Changing a photo, but you didn't like the result, don't be too desperate. 80 percent of the time, it's solved without root rights and complicated manipulation. The key is to understand that the display algorithm depends on the aspect ratio of your Xiaomi screen and the firmware version.

Why is the photo on the call not displayed on the whole screen?

Before you start setting up, it is important to understand why. MIUI It cuts off your contacts, and there are several reasons, and they depend on your smartphone model:

1. The pruning algorithm in MIUI. By default, the system centers the image and trims it to a square (ratio 1:1), even if the original is 16:9 or 18:9. This is done to unify the display on all devices, but looks suboptimal on modern smartphones with elongated screens.

2. Screen resolution and cutouts. On models with AMOLED-displays (e.g., Xiaomi) 12T or POCO F5) The system takes into account the notch area under the camera and does not stretch the image into this area).

3. limitations of the Phone app. In some versions MIUI (especially 13-14) the call app is rigidly tied to display patterns that do not take into account user zoom settings.

4. Format of the original image. If you upload a photo with a resolution less than 720×720 px or in.webp format, the system automatically reduces it to the minimum allowable size to avoid pixelation.

⚠️ Note: On HyperOS devices (such as Xiaomi 14 Ultra), the logic of displaying a photo on a call has changed, and here we use an adaptive algorithm that adapts to the content of the image. If the photo is dominated by dark colors, the system can artificially reduce its size, so as not to merge with the black frames of the screen.

To check what exactly is the reason why the photo is not stretching, try the following:

• 📱 Contact the test image with permission 1080×2400 px (ratio) 9:20 — It is optimal for most Xiaomi).
• 🔍 See how it appears in the Gallery when viewed in full screen mode.
• 📞 Call from another phone and compare the results.

Method 1: Standard MIUI settings (without third-party applications)

Let’s start with the simplest method that works on most Xiaomi, Redmi and other devices. POCO s MIUI 12-15 You do not need to install additional programs or obtain root rights.

1. Open the Contacts app and select the contact you want.

2.Click Edit (pencil icon in upper right corner).

3. Touch the current contact photo and select Change the photo.

4. Upload a new image from the Gallery or take a picture with the camera.

• 🖼️ If you choose a photo from a gallery, the system will suggest that you cut it into a square. Don't confirm the cropping right away! First stretch the edge of the cropping to its maximum width, then tighten the top and bottom edges to grab the entire screen.
• 📸 When shooting a new photo with the camera, try to take a picture in landscape orientation - so there is more chance that the system will properly scale the image.

5. After selecting the photo, click Ready and save the changes.

6. Important step: Go back to the contact editing menu and click on the photo you just installed again. MIUI You get the full-screen (or stretch) option, and if you don't, you go to the next one.

⚠️ Attention: On devices with MIUI 14 and later (e.g. Redmi Note 12 Pro)+) The stretching option can be hidden. To activate it, pre-enable the developer mode: go to Settings → The phone. → Version. MIUI and click on this item 7 times. Then go back to the Additional Settings → For developers and enable debugging by USB. After that, the option to stretch the photo should appear.

Select an image with at least a resolution 1080×2400 px

Cut it in the editor to a 9:20 aspect ratio (for most Xiaomi)

Save it in format. JPEG quality 90%+

Check that the photo does not have important details around the edges (they may be cut off)

If the standard method didn't work, don't worry, we have a few other options, like using hidden settings in the Phone app that few people know about.

Method 2: Change the settings of the "Phone" application through the engineering menu

This method is suitable for advanced users and requires caution, as incorrect actions in the engineering menu can lead to failures, but it often helps to stretch the photo to the full screen when the standard methods do not work.

1. Open the Phone application and type the code:

##4636##

5.In the Call Settings section, search for the Photo Display Mode option and select Stretch to Full Screen or Fit to Screen.

6 Save the changes and restart the phone, and then the contact photos should be displayed on the full screen.

If the engineering menu doesn’t open or the options aren’t available, it means your Xiaomi model doesn’t support this method, so move on to the next one.

Another working option is to reset the phone app to factory settings. → Annexes → Application management → Phone. → Warehouse → Clear the data. Attention: this will delete the call history!

Method 3: Using third-party applications to make calls

To return a standard application, go to Settings → Annexes → By default. → Phone app and select the phone.

Method 4: Manually editing a photo before uploading

Sometimes the problem isn't with the smartphone settings, it's with the image itself, MIUI It automatically reduces it. To avoid this, edit the image before downloading.

Optimal photo parameters for full-screen display:

• 📏 The aspect ratio is 9:20 (for most Xiaomi 2022-2026) or 9:19 (for older models).
• 🖼️ Permission: not less 1080×2400 px (for Full) HD+ screen).
• 🎨 Format: JPEG or PNG (avoid WEBP and HEIC).
• 🌈 Color scheme: avoid dark backgrounds AMOLED-screens can be combined with the frames.

How to prepare a photo:

1. Open the image in any graphics editor (e.g. Photoshop, GIMP or even Canva).

2. Cut it to a ratio of 9:20.

• In Photoshop: Select the Frame Tool (C) → Specify the ratio 9:20 → trim.
• In Canva: Create a new project with a size 1080×2400 px and upload the photo there.

3. Increase contrast and brightness so that the photo reads well on the screen.

4.Save in format JPEG quality 90-100%.

5. Upload the edited photo to contact via Contacts → Edit → Change the photo.

• PicsArt is a pruning tool with a given aspect ratio.
• Snapseed – allows you to fine-tune the scale and positioning.
• Lightroom Mobile is suitable for color correction and contrast.

After editing, export the photo in maximum resolution.

If you don’t want to mess with editing, you can use online services, for example:

• 🌐 iLoveIMG – trimming with a given ratio.
• 🌐 Photopea is a full-fledged online analogue of Photoshop.

Method 5: The use of topics and customization MIUI

Few people know, but in MIUI There are hidden themes that allow you to change the display of the call screen, including the size of the photo. MIUI 13-15 and does not require root rights.

1. Open the Themes app (icon with brush).

2. Go to My Profile section → My subjects. → Local.

3. Click on the three dots in the upper right corner and select Import.

• 🎨 MIUI Mix – allows you to configure the scale of the elements of the call interface.
• 🎨 Pixelify – imitates the call screen from Google Pixel with a large photo.

5. After applying the theme, restart the phone and check the photo display when an incoming call is made.

If the theme doesn’t fit, you can delete it in the same Locals section by clicking Delete.

⚠️ Note: Installing third-party themes can lead to: 🔄 Failures in standard applications (e.g. Phone or Messages). 🛡️ Loss of warranty if the theme modifies system files. 🔋 Increased battery consumption due to unoptimized animations. Create a backup before installation via Settings → Additionally. → Backup and reset.
