How to install a photo on a call on Android Xiaomi on the full screen

Xiaomi smartphone owners often face the annoying feature of the MIUI interface: instead of the expected portrait of the subscriber on the entire display, they see only a small round avatar in the corner of the screen. This is not a bug or a breakdown, but the specific logic of the system, which by default tries to keep the visibility of the interface using a blurred copy of the image as a background. However, for many users, it is important to see a clear photo of the contact occupying all the useful area of the display, especially if you often use the smartphone in a horizontal position or just prefer the visual style of pure Android.

The problem is not solved by a single magic button, but by a set of settings that depend on the firmware version, region and the caller application used. In this article, we will examine all possible ways, from standard gallery settings to hidden developer settings that will help you personalize the call screen, you will learn why the photo is cropped, how to crop the image correctly and what applications can help if Xiaomi’s regular tools do not give the desired result.

Before making any changes, it’s important to understand that display quality is directly dependent on the resolution of the original file.The system can ignore settings if the image is too small or has a non-standard aspect ratio.We’ll look at how to prepare the media file to display correctly on any model, whether it’s a budget Redmi or Xiaomi’s flagship Mi series.

Why not the full screen: MIUI features

The MIUI interface has its own unique contact processing algorithms. Unlike stock Android, where photos are often stretched, it has a prioritization system. If a contact doesn't have a high-resolution photo, the system automatically generates a plug or uses a small preview version, blurring it in the background, which is designed for aesthetics, but often interferes with the caller's identification.

The key factor is linking the image to the contact in the phone book, not to the chat in the messenger or social network. Many users mistakenly believe that installing an avatar in Telegram or Viber will automatically display in the usual way. GSM-It's not a call, but it's not. To be able to show the full screen, the data needs to be synchronized with your local phone database or your Google account.

It’s also worth considering that in some firmware versions (especially in Chinese or global versions with recent security updates), the framing algorithm has become more aggressive: it tends to place the face in the center, cutting edges, which can lead to the loss of important image details.

• 📱 Prioritizes the central part of the face, ignoring the edges of the photo.
• 🔄 Syncing with Google Contacts Can Overwrite Local Settings.
• 🎨 Shell MIUI By default, applies the blur effect (blur) to the background.

Image Preparation: Format and Size Requirements

For a photo to take up the entire screen without black fields and distortion, the source file must meet certain technical parameters. Standard camera images often have a 4:3 aspect ratio, whereas modern displays of Xiaomi smartphones are elongated (19.5:9 or 20:9). If you download a regular photo, the system will either crop it or leave empty fields.

The best solution is to pre-fracture the image in proportion to your screen. For most modern Xiaomi models, this ratio is close to 9:16 (vertical). You can use any built-in editor in the gallery to crop the photo before installing, which ensures that the face of the contact does not “go” outside the visible area.

Image resolution also plays a role. You shouldn't use files that weigh less than that. 200 Kb or resolution below 720p — They'll look grainy and fuzzy on big screens, but they'll also have giant files from professional-grade cameras weighing in at the same time. 10-20 MB can be processed longer by the system when loading the contact list.

⚠️ Warning: Avoid using images with transparent background (format) PNG Android can interpret transparency as black or white background, which will spoil the appearance of the call screen.

💡

Use photo editing apps to set the 9:16 aspect ratio in advance, which will save you time when installing an avatar.

Main method: installation through the Contacts application

The most reliable and standard method, which works on 95% of Xiaomi devices, is editing the contact card directly through the system application. SIM-Google card or account correctly, without synchronization conflicts.

To start, open the standard Contacts app (a yellow icon with a person's silhouette). Find the right subscriber in the list or search. Click on the contact name to open the full card. If you see the Change button (usually a pencil or text at the bottom), click on it. In editing mode, find the camera icon or circle with a silhouette at the top of the screen.

Once you click on the camera icon, the system will tell you to choose the source: take a photo or choose from a gallery. Select the Gallery and find the prepared image. At this stage, the framing interface will open. This is where you decide whether the photo will be on the full screen. You need to push the framing frame to the maximum so that it covers the entire area of the future display, ignoring the system's advice to "put the face in a circle."

Once the selection is confirmed, the system can suggest saving changes to a specific account (Google, Xiaomi or Phone). For maximum compatibility and display on all devices, it is better to choose a Google account if contacts are synced, or local phone storage if you do not want to depend on the network.

Alternative method: through the Gallery and Settings

Sometimes the direct contact method is not good enough or the framing interface is too tight for the highlight area, and in such cases you can try the "sly" method through the system gallery. This method often allows you to specify the display area more accurately, since the editing tools in the Xiaomi Gallery are more functional.

Open the Gallery app and select the photo you want. Click More (three dots) and select Set How. From the menu that appears, select Contact Photo. The system will take you to the contact list. Select a subscriber. The feature of this method is that the Gallery can offer more flexible cropping tools before the final installation.

If that didn't work, and the photo is still small, try changing the theme. Some third-party themes for MIUI have their own call screen templates that force you to change the style of the avatars. Go to the Themes app, find a theme with a minimalist call screen, and apply it. This can change the display logic without deep system settings.

Using third-party calls for full screen

If Xiaomi’s standard tools flatly refuse to show photos the way you want (e.g., leaving black bars on the sides), the only radical solution is to replace the call app. There are plenty of alternative “calls” on the Google Play Store that completely ignore the system limitations of MIUI.

Popular apps like Truecaller, Call Contacts, or Simple Dialer let you customize the incoming call screen regardless of the system. You install the app, give it permission to call and access contacts, and then in Android settings (Default Apps). → You pick your phone, and then you open the interface of the new app when you call it, and you can stretch it 100 percent of the screen without cutting it.

However, there is a downside to this method: Third-party calls can consume more battery life, as they are constantly hanging in memory, waiting for a call. In addition, on some Xiaomi models with aggressive battery optimization, such applications can be killed by the system in the background, which can cause you to miss a call or see a standard screen instead of a custom one.

• 📞 Truecaller: a powerful number determinant, but heavy and with advertising.
• 🎨 Call Contacts: great customization, but requires manual rights setting.
• 🚀 Simple Dialer: lightweight, no advertising, but minimal features.

⚠️ Warning: When installing a third-party call, be sure to give it permission to work in the background and remove battery restrictions in the App settings → [Your call] → Battery → There's no limit, otherwise the call screen may not be on time.

Problem Solving: Photos are cropped or not saved

Even following the instructions, users may encounter technical difficulties, and one of the most common problems is that the photo is saved, but when the call is displayed a standard gray plug. SIM-The map, the other one in Google, the third one in Xiaomi Cloud, and the system can pull up a post without a photo, so you can combine duplicates or delete redundant records.

Another common situation is that there is a photo, but it is heavily cropped (only the nose or forehead is visible), which is because the framing frame was too narrow, unfortunately, MIUI doesn't have the function of "moving the photo inside the circle" after saving, so you have to go back to editing the contact, delete the current photo and upload it again, this time making the frame wider, capturing more space around the face.

If the photo is not saved at all (the OK button is inactive or gives an error), check the free space in the smartphone memory and access rights. the Contacts and Gallery app need permission to read and write files. Also try to reboot the smartphone - this is a banal but often working tip that resets temporary errors of the media scanner service.

💡

The main cause of photo problems is duplicate contacts from different sources (SIM, Google, Phone), always check which recording you upload the image to.

In some cases, cleaning the Contacts and Contacts (SIM) app cache helps. Go to Settings → Apps → All apps, find Contacts, click Clear and select Clear Cache (not data to keep numbers from losing!).
