How to take a photo of a full screen caller Xiaomi Redmi

Personalizing the smartphone interface not only allows you to express your personality, but also makes navigation much easier. When a friend or colleague calls, it is much more pleasant to see his face on a large display, rather than a small thumbnail in the corner. Owners of Xiaomi and Redmi devices often find that after a system update or firmware change, the standard behavior of the gallery changes, and photos stop showing on the full screen.

This is because of the MIUI shell and the new HyperOS, which are very strict about how applications access their contacts, and if you're used to seeing a full-length subscriber, but you're only seeing a square preview, you've either lost your settings or changed your system's algorithm, but it's pretty easy to get back the functionality you want, if you know which menus you want to look at.

In this article, we will discuss all the current ways to install full-screen photos on an incoming call, we will look at both standard methods through the Contacts app and workarounds through the system gallery, and we will also touch on the nuances of working with different versions of the operating system, so that the instruction is useful for owners of both old and newer models of smartphones.

Features of the call interface in MIUI and HyperOS

Xiaomi’s shells have deep integration with its own services, creating a unique ecosystem but sometimes making things more difficult. MIUI has long used its own call display engine that automatically scaled contact images. With the advent of HyperOS and the update of Google Phone components, the logic of the work has changed.

Now, priority is given to Google's standard Phone app, which can conflict with the system gallery. If you've recently upgraded and your photos are gone or shrunk, the problem is that you're not synchronizing access rights between apps. Security can block access to high-quality images, only showing low-resolution previews.

Also, it is important to consider the format of the source file: vertical shots are stretched to the full screen most correctly, while horizontal ones can be cropped or displayed with black fields. For perfect full-screen display, photos with an aspect ratio of 9:16 or higher are best used, which ensures that the subscriber’s face is not hidden by the interface elements.

Preparation of high-quality images for contact

Before installing a photo, you need to make sure that the image file meets the technical requirements of the system. Poor or too heavy image may not appear correctly, turning into a blurred spot or a standard stub with letters.

Use a built-in editor or third-party framing apps. Make sure the person's face is in the center of the frame, as in full-screen mode, the edges can hide under the answer buttons or the caller's name. High resolution is important, but don't download files weighing more than 5-10 MB, as this can slow the caller's card open.

Save photos in JPG or PNG. Other formats, such as HEIC (often used on iPhones), may not be supported by standard Android tools without converting. If you take a photo from instant messengers, make sure it is saved in its original quality, not as a compressed preview version.

Method of installation through the application "Contacts"

The most reliable and classic method of linking an image is to use a regular phone book management app, which ensures that the photo is synced to a Google or Mi Account account and displayed correctly when calling from other devices.

To start, open the Contacts app on your Redmi smartphone. Find a subscriber in your list or create a new contact by clicking on the plus in the corner of the screen. After opening the user card, look at the round area at the top where the person icon usually resides.

Click on this area or the Change button (often looks like a pencil). In the edit menu that opens, again tap the photo space. The system will suggest you choose the source: take a picture with the camera or choose from the gallery. Choose the second option and find the prepared image.

Once you select a photo, the system will suggest that you crop the image, move the frame so that your face is clearly visible, and press "Done" or "Save." Importantly, if the contact has multiple numbers, the photo will be attached to the entire contact, not to a specific number.

Some firmware versions require you to restart the Phone app after saving it to make the changes effective. If you see a photo immediately after installation but it doesn't appear when you call in, try clearing the Phone app's cache through the settings.

Configure through the System Gallery

If the standard contact path is not working or the photo is cropped incorrectly, you can try the reverse method through the Gallery app, which often helps when you need to manually specify the display area that the system missed when automatically framing.

Open any suitable photo in the gallery. Click on three dots in the corner of the screen or swipe up to open the additional menu. In the action list, find Set as or Use as. Select Contact Photo.

The system will suggest you pick a contact from a list, find the right person and confirm the choice, and the advantage of this method is that you can immediately see how the photo will fall on the screen, and you can zoom in before the final save.

⚠️ Note: When installing a photo through a gallery, make sure you choose the contact stored in your phone’s memory or Google account, rather than in hidden or system groups that may be restricted.

If the image doesn't become full-screen after this manipulation, it may be the design theme that is the problem, and some third-party themes downloaded from Themes are forcibly changing the style of the call screen, ignoring the system settings of the image.

Solving Display and Scaling Problems

A common problem with Xiaomi users is that the photo is set, but when you call it, it only takes up part of the screen or looks blurry. This often happens due to a conflict of permissions. The system can take thumbnails from the cache, ignoring the high-quality original.

To solve this problem, go to Settings → Apps → All apps. Find Contacts and Phone in the list. For each of them, select Memory and click Clear Cache (not to be confused with Clear All Data to avoid losing numbers).

Another reason may be the feature “Improving the image” enabled or «HD-call-ups SIM-Try temporarily disabling VoLTE or Wi-Fi Calling and see if the behavior of the call screen changes. Sometimes telecom operators transmit a video stream that blocks the static photo.

💡

Tip: If you use a dark theme, make sure that the photo you choose has a contrasting background, otherwise, when you call at night, the subscriber’s face may merge with the black interface of the MIUI shell.

Use of third-party applications for calls

Staff tools don't always meet the needs of advanced users. If you want to have full control over the look of the call screen, including animation, transparency and photo location, it's worth considering alternatives. App stores offer a variety of solutions that replace the standard interface.

One of the popular solutions is the Truecaller app, or specialized dialers like EX Dialer, which allow you not only to identify unknown numbers, but also to customize the appearance of the caller's card to the smallest detail, you can specify the specific size of the photo, his position and even the background video.

However, it is worth remembering that installing a third-party call app requires broad permissions, the app will have access to all your contacts and call history, and the security of the data depends on the developer’s reputation.

To install such a solution, download APK-If you have a file or find an app on Google Play, Android will ask for default permission to use it, confirm your choice, and when you call in, you'll see the interface of the new app with your full-screen photo set up.

⚠️ Note: On newer versions of Android (13 and above) and HyperOS shell, the system can aggressively close the background processes of third-party calls. Be sure to turn on the “No Limits” mode in the battery settings for the selected application so that you do not miss the call.

The main secret of a full-screen photo is the vertical image format (9:16) and install it through the contact editing menu with subsequent manual adjustment of frame boundaries.
