Modern Xiaomi smartphones offer users many options for personalizing the interface, and one of the most popular features is to set your own image to an incoming call. However, the standard behavior of the MIUI system or the new HyperOS shell often does not live up to expectations: instead of a beautiful full-screen photo, the user sees only a small square in the corner or a blurred background that completely hides the face of the interlocutor. This is due to the peculiarities of framing algorithms and protection against burnout of the matrix, but the situation is quite possible to fix.
To have a full screen photo when you call Xiaomi, it is not enough to simply select a picture in the gallery and click "Install". You need to consider the aspect ratio of your display, the resolution of the original image and the settings of the specific application through which the call is made. In this article, we will discuss all the nuances of configuration, from standard system tools to the use of third-party utilities for perfect display.
Owners of devices with AMOLED-screens are particularly interested in the correct setting, as a static bright image can lead to uneven wear of the pixels, so the system often forcibly reduces the display area or adds blur. Understanding these processes will allow you to find a balance between aesthetics and preserving the display life, while ensuring maximum informativeness during the incoming connection.
Why a photo doesn’t stretch across the entire screen by default
The main reason why the image does not occupy the entire display area is the difference in proportions. Most photos are taken in 4:3 or 3:4 format, while modern Xiaomi smartphones have elongated screens with an aspect ratio of 19.5:9 or 20:9. When you try to stretch a normal photo on such a screen without distortion, the system automatically trims the extra edges or adds black fields, which visually reduces the useful area of the picture.
In addition, there is a built-in protection mechanism in the MIUI shell that prevents important interface information such as response buttons, resets, or the name of the contact person from overlapping. System constraints dictate their rules: if the algorithm thinks that the face in the photo will merge with the control buttons, it will force the image to zoom in or apply the blur effect to the background, leaving only the central part clear.
⚠️ Warning: Trying to bypass system restrictions with modified system files can cause the phone to malfunction or display artifacts on the screen during a call.
Also, it's worth considering that different call apps handle graphics differently: The standard Google Phone, which is often pre-installed on global firmware versions, and the native MIUI Dialer (Chinese version) use different rendering engines. So a solution that works for one application may be useless for another, which requires a customized approach to customize each case.
💡
Use high-resolution photos (minimum 1080x2400 pixels) so that the clarity of facial details is not lost when zooming.
Configure the display through the standard gallery
The easiest and most reliable way to install a photo is to use the built-in Gallery app, which ensures compatibility with system contacts and does not require the installation of additional software, but there are secrets to achieving maximum screen filling.
To start, open the image in the gallery. Before installation, we recommend framing pre-fracture. Press the edit button (usually a pencil or slider) and select the "Capture" tool. Here, it is important to manually place the frame so that it repeats the proportions of your screen, that is, it is as elongated as possible. If you just select the face in the center, the system will crop the top and bottom when installed.
After framing, click the "More" button (three dots) and select "Install as." In the menu that appears, select "Contact Photo." The system will suggest selecting a contact from the list or creating a new one. At this point, it is critical to properly configure the display area.
☑️ Check before installing the photo
When the slider preview window opens, don't rush to click "Ready." Pull your fingers to move it up or down, fitting it under the front camera or speaker if necessary. Some versions of MIUI allow you to choose the display style: "Center", "Stretch" or "Fill." Choose the "Fill" option so that the photo takes up all available space, even if part of the edges are cropped.
It is worth noting that if you install a photo for a contact that already has an image, the new one may not apply immediately due to caching, in such cases, it helps to reboot your smartphone or clean the cache of the Contacts app. Also make sure you edit the exact contact that is stored in your phone’s memory, not just your Google account or your phone’s Google account. SIM-map, as synchronization sometimes resets user display settings.
Use of the "Themes" application for customization
If standard methods don't work, Xiaomi's official Themes app comes to the rescue, a powerful tool that allows you to change not only wallpaper, but also system fonts, icons, and call profiles. In the theme store, you can find special packages that change the incoming call interface, making the photo full-screen.
To find the desired design, open the Themes app and enter queries like Full screen caller, Photo caller or Big photo call in the search bar. You will find many free and paid options. Pay attention to the screenshots in the theme description: if they show a full screen photo without frames, then this theme will suit.
Once you download and apply the theme, the call interface will change globally, but it has its own peculiarities: first, with the new call style, the dialing style often changes, which may be unusual; second, some themes may not work properly with certain phone models, causing the response buttons to shift.
- 📱 Open the "Themes" app on the main screen.
- 🔍 Enter in search of "Caller" ID" or "Time of the call".
- 🎨 Select a theme marked “Customizable” or look at screenshots.
- ⬇️ Download and apply the theme, then check the incoming call.
It's important to understand that using a theme is a systemic change, and if you don't like it, it can be easily removed by returning to the standard style, so go to the user profile inside the Themes app, go to My Themes, and select the standard theme Classic or Untitled.
Third-party applications for call management
When the built-in HyperOS and MIUI capabilities are exhausted, users turn to third-party developers. There are many apps on the Google Play store that are specifically designed to replace the standard call interface, which allow you to display high-resolution photos, add animations and even video backgrounds.
One popular solution is the Truecaller app, or specialized "Dialer" applications, which run on top of the system interface, and once you install it, you'll need to give it extensive permissions: access to contacts, phone, overlays, and work in the background, without which permissions, the app won't be able to intercept an incoming call and show you your photo.
The advantage of these programs is the flexibility of settings: you can adjust the sensitivity zones, the transparency of the buttons, the speed of the photo and even the response to the phone coming to the ear. However, it is worth remembering the resource consumption: third-party applications can land the battery faster, since they are constantly active waiting for a call.
⚠️ Note: When installing third-party number detectors, read the privacy policy carefully as they access your entire phone book.
To install photos through these apps, you usually need to go to their internal settings, find the Caller Screen or Call Screen section, select a contact and upload an image. Often these apps have their own photo databases (for example, from social networks), which allows you to automatically upload avatars even for those contacts where you did not save the photo manually.
Comparison of methods of displaying photos
To make it easier for you to choose the best way, we have prepared a comparison table that will help you evaluate the pros and cons of each method depending on your priorities: picture quality, stability or availability of additional features.
| Method | Photo quality | Stability | Difficulty setting up |
|---|---|---|---|
| Standard Gallery | Average (depending on framing) | Tall. | Low. |
| Annex Topics | High (depending on the topic) | Medium | Low. |
| Third-party Dialer's | Maximum. | Low (interface bugs) | Tall. |
| Google Contacts | Low (strong compression) | Tall. | Low. |
As you can see from the table, the middle ground is often the use of those or carefully configured through the gallery. Third-party apps give better visuals, but can conflict with the system, especially after Android updates. Google's standard tools often sin strong compression of images, which makes the photo on the screen look pixelated (in pixels).
Why does Google Contacts look worse?
Solving problems with scale and quality
Even after all the settings, you may find that the photo looks pale, too bright or improperly cropped. Often the problem lies in the file format. Xiaomi systems work best with JPG or PNG format. If you use a photo in HEIC format (the iPhone standard), convert it before installation, as color reproduction errors can occur when converting on the fly.
Another common problem is jumping photos. When a call comes in, the image can appear in a small window and then spread out over the entire screen. This is normal MIUI animation behavior. You can speed up by turning off animations in the Developer section, but it will make the interface less smooth overall.
If the photo contact is displayed in black and white or inverted, check the image enhancements settings or filters in the gallery before installing. Sometimes the system engine misinterprets the color profile (sRGB vs. DCI-P3). Try to save a copy of the photo with a different color profile.
- 🖼️ Convert the photo to JPG before installation.
- 🎨 Make sure that the sRGB color profile.
- 📐 Use apps to accurately framing to screen resolution.
- 🔄 Reboot your phone after replacing your contact photos.
If nothing works, and the photo is still cropped, you can go to a trick: add black fields on top and bottom in the graphics editor to the photo, creating the illusion of a more elongated frame, then when the system automatically framing the "important" center with the face will remain in the visible zone.
💡
The key to success is that the original photo should be vertical and have a resolution of at least your screen resolution (e.g. 1080x2400).
