How to take a photo of a caller in full screen on Xiaomi Redmi Note 9

Owners of Xiaomi and Redmi smartphones often face the problem when an incoming call a photo of the contact is displayed only as a small circle or not at all. For the Redmi Note 9 model running on the MIUI shell, this issue is solved not only by adding a contact to the phone book, but also by correctly configuring the system theme. Standard “black” themes often limit the functionality of the Caller ID display, cropping the image or hiding it behind graphical elements of the interface.

To make the caller visible as large and clearly as possible, you need to make sure that the theme you are using supports full-screen call mode. In some cases, the problem lies in the low resolution of the uploaded photo or the access rights of the Phone application. We will take into account all the nuances, from choosing the right image to the hidden system settings that affect the visualization of the incoming call.

Preparation of high-quality images for contact

The first and most obvious step is to have the photo in contact. However, simply adding a picture from a gallery is not enough - the system can automatically compress it or crop it unsuccessfully. For the Redmi Note 9 with its high-resolution screen, it is recommended to use good quality source materials. The image should be square or vertical to avoid distortion when zooming.

When you upload a photo through the standard contact menu, the system will suggest you select a framing area. Pay attention to the centering of the face: if you move the frame too close to the edges, when you call, part of the face may be cut off with black fields or an interface. It is better to leave some space around the head, since some themes have dynamic elements that overlap the edges.

If you want a photo to look professional, use third-party editors before uploading. Process the image, align the white balance and make sure the face is well lit. Dark or blurred shots on the Redmi Note 9's big screen will look unaesthetic. After editing, save the file in high resolution, such as 1080×1080 pixels.

  • 📸 Use original high-resolution photos, avoiding photos from messengers with strong compression.
  • ✂️ Center your face when framing, leaving small indentations from the edges of the frame.
  • 🌈 Check the contrast of the image so that the face is clearly visible even in bright light.

⚠️ Attention: Images in format HEIC (iPhones may not be displayed correctly in older versions MIUI. Convert them into JPG before installation.

Selecting and setting the appropriate theme of design

The key factor determining whether a full-screen photo of a caller will be an active theme. The standard Classic or Default theme in MIUI often has a limited call screen design, where the photo occupies only a small part of the display. To implement the Full Screen Caller ID feature, you need to download a theme that supports this functionality.

Open the Themes app on your Xiaomi Redmi Note 9. In the search box, type in "Full screen call", "Big photo" or "HD Call". In the search results, pay attention to the preview: screenshots should show that the photo of the contact occupies the entire screen, and the response and discard buttons are on top of the image or at the bottom without the face overlap.

Once you download and apply the theme, be sure to restart the device, which is a critical step, because the resources of the call interface are loaded when the system starts. If you just switch the theme without rebooting, the old interface cache can retain the same look of the call screen.

There are plenty of free themes from independent authors who specialize in minimalism and large images. Look for high-rated themes and high-downloads to ensure compatibility with your version of MIUI. Don't be afraid to experiment: installing a theme takes a couple of minutes, and the result can dramatically change the visual experience.

Configure access rights and permissions of the application

Even with a perfect theme and high-quality photo, the system can block the display of an image due to privacy restrictions. In modern versions of Android and MIUI, applications must have explicit permission to access contacts and storage. Without this, the Phone app will not be able to pull the picture from the gallery at the time of the call.

Go to the Settings menu, then select the App and find “All Apps.” In the list, find the Phone system app (blue handset icon) and the Contacts app. For each, check the Permissions section. Make sure that Contacts, Memory, and Phone are allowed.

Also worth checking the battery settings. MIUI's energy saving system can aggressively "sleep" background processes, which may cause photo loading to be delayed or not at all. In the battery settings for the Phone app, select "No restrictions" mode.

☑️ Access rights verification

Done: 0 / 1

If the problem persists after turning on all permissions, try clearing the app cache.This won't delete your contacts, but will reset temporary files that may have been corrupted. Go to Settings → Apps → Phone → Memory and click Clear Cache.

Use of third-party applications for calls

The built-in MIUI tools sometimes have bugs or limitations that cannot be overcome by standard methods, and in this case, third-party dialing apps come to the rescue, completely replacing the standard call interface, and one of the most popular and reliable solutions is the Truecaller or Call UI application.

Once you install an app like this, it will request the rights to manage calls, and you have to agree, because it will intercept the incoming call and display its window on top of everyone else, and these apps often have a Design or Themes section in their settings where you can choose the Full Screen style and adjust the transparency of the buttons.

However, this method has its drawbacks: Third-party callers consume more battery life and may conflict with system-based conversation recording or numbering functions in some regions, and require a stable Internet connection to run a number database.

  • 📱 Download the proven application to replace the call interface from Google Play.
  • ⚙️ Provide the application with all the permissions requested, including “Above other windows».
  • 🎨 Select in the application settings style with full-screen photo.

⚠️ Warning: When installing a third-party “caller” the standard Xiaomi conversation recording feature may stop working or record silence.

Compatibility and Problem Solutions Table

For quick diagnosis of the problem, it is convenient to use a pivot table to determine which component of the system prevents the full-screen display of the photo on your Redmi Note 9.

If none of these things worked, it may be a specific bug in the MIUI version. In this case, it’s worth checking for system updates. Sometimes Xiaomi releases patches that fix interface errors. Go to Settings → About phone and click on the MIUI version to check for updates.

Specifics of working with WhatsApp and messengers

It is important to distinguish between regular phone calls and Internet calls (WhatsApp, Telegram, Viber), which are set up separately. WhatsApp requires you to go to the settings of the app itself, click on the profile avatar and upload a photo. However, a special theme is needed to ensure that the WhatsApp caller’s photo is displayed on the full screen in the same way as a regular call.

Many MIUI themes have separate settings for System Calls and WhatsApp Calls. When choosing a theme in the store, pay attention to the description: it should indicate whether it supports WhatsApp Full Screen. Without such support, messengers will show a standard small window.

The secret of setting up WhatsApp calls
To fully work full-screen photos in WhatsApp may need to include special flags in the developer menu or use modified versions of the application, but this carries security risks.

Also make sure that WhatsApp notification settings allow “pop-ups” or “over other apps” to be displayed. Without this permission, the system will block full-screen deployment when a video call is made.

Frequently Asked Questions (FAQ)

Why is the photo still small after the theme is installed?
Chances are, you didn’t restart your phone after installing the theme, the call screen resources are cached at launch, and also check that the theme does support your Android version (Android 10/11/12), as old themes may not work properly on new firmware.
Can I take a full screen photo of a caller without setting themes?
On a standard MIUI shell, it's almost impossible to do this without installing themes, because the design of the call interface is rigidly set by developers, and the only option is to use third-party caller applications that overlap the standard interface.
Does the Android version affect the display of the photo?
Yes, it does. Caller ID has changed in different versions of Android. Redmi Note 9, which was updated to Android 11 and 12, may have different permission requirements. Make sure the theme is tailored to your current version of the software.
What to do if the photo is black and white?
This is a feature of the chosen theme: many minimalist themes use a monochrome style, and to return the colors, you either need to change the theme to a brighter one, or find a color switch (if the author provides one) in the current theme settings.
