Photo of the full-screen caller Xiaomi Redmi Note 9 Pro

Xiaomi smartphone owners often face the need to personalize the device, making it not only functional, but also recognizable. One of the most useful features is the ability to set a photo of the caller that occupies the entire screen during an incoming call, which allows you to instantly identify the interlocutor without being distracted by reading the name or number, which is especially convenient in noisy environments or in poor vision.

However, the MIUI shell installed on the Redmi Note 9 Pro has its own nuances. Standard system settings do not always allow you to stretch the image over the entire display, often leaving black fields or cropping the face. In this article, we will discuss in detail how to properly prepare and install the image to display it correctly, and also consider the work of third-party applications if the standard functionality does not suit you.

To start with, it’s important to understand that the display quality is directly dependent on the resolution of the source file and the screen proportions of your gadget. Xiaomi Redmi Note 9 Pro features a display with an aspect ratio different from the classic square avatars, so simply adding photos to contacts may not give the desired effect. We will look at all available methods, including hidden settings and using the MIUI gallery.

Image Preparation and Format Requirements

Before you start installing, you need to make sure that your image meets the technical requirements of the device. The screen of the Redmi Note 9 Pro is high resolution, and using the slightest pictures will result in "grain" and blurring when calling. The optimal solution is to use photos at a resolution of at least 1080x2340 pixels.

Also, you should pay attention to the composition of the frame. Since the subscriber's face is usually centered by the system, make sure that important details are not located at the very edges of the image, as they can be cropped by the call interface. Close-up portraits are best suited.

• 📸 Use high quality source codes to avoid pixelation on AMOLED-screen.
• 📐 Observe vertical orientation of the image to better fill the space.
• 🎨 Avoid too colorful backgrounds that can distract from the caller’s face.

If your photo is horizontal, you'll have to crop it. The gallery editor built in allows you to do it quickly, but it's better to use specialized cropping apps where you can set the exact proportions of your smartphone screen, which ensures that once installed, the picture doesn't stretch disproportionately.

For the perfect result, crop the photo in proportions of 9:19.5 before downloading to the phone – this is the native ratio of the screen of the Redmi Note 9 Pro.

Installation of photos through the standard MIUI Gallery

The easiest and most reliable way to set a photo on a call is to use the built-in gallery functionality, which requires no additional software installation and works consistently on all firmware versions. The algorithm is intuitive, but requires careful consideration when choosing the type of installation.

Open the Gallery app and select the image you want, click on the More button (three dots in the corner of the screen) and find "Set as Wallpaper." Here, the system will offer several options: lock screen, desktop or contacts, and that is the last item we need.

⚠️ Note: If you select Lock Screen, the photo will only change when the phone is turned off, not during an incoming call.

Once you select Contacts, the system will suggest that you select a particular subscriber from your phone book, find the name you want and confirm the action. Now, when you call that person in, you will see the image you've selected. If the photo is cropped incorrectly, the system may suggest that you move the framing area, use this opportunity to fine-tune it.

Configure via Contacts and Synchronization

An alternative method involves direct editing of the contact card itself. This method is useful if you want to change the photo without opening the gallery again, or if the image is already uploaded to the cloud. Open the Contacts app, find the desired subscriber and click on the edit button (usually a pencil or an "i" icon in a circle).

In edit mode, click on the contact avatar. The system will suggest you pick a photo from the gallery or take a new picture. Once you select the image, you will see the framing interface. Here, it is important to set the frames correctly so that the face does not go into the darkened area of the call interface.

Special attention should be paid to sync. If you use a Google or Mi Cloud account, changes can be applied with a delay. Make sure that contact sync is enabled in Settings → Accounts and Sync settings. This will allow the caller’s photo to be displayed on the full screen even after resetting or changing the device.

Sometimes, after updating the system, the display settings may get lost, in which case it is recommended to re-install the installation procedure for key contacts. This takes a couple of minutes, but ensures that the Redmi Note 9 Pro will correctly display visual information about calls.

Use of third-party applications for Caller ID

Standard MIUI functionality is sometimes not enough, especially if you want to see photos not only from contacts from the phone book, but also from unknown numbers found on social networks.

These apps are layering on top of the standard call interface, and they can pull up avatars from Facebook, Instagram, LinkedIn, and other sources, but it's worth remembering that installing them requires broad permissions to access contacts and call logs, which can affect data privacy.

• 📱 Truecaller is a market leader with a huge database of numbers and photos.
• 🔍 GetContact – popular in the CIS, finds a photo in messengers.
• 🛡️ Hiya – focuses on security and identifying spam with photos.

Once you install this app, you need to go to its settings and activate Caller ID or Caller ID. Android will ask permission to use the default number app -- you'll agree with that. Now, when you call, you'll open the full-screen photo app interface, not the standard MIUI call.

Display problems and black fields

A common problem with Xiaomi users is that they have black bars on the top and bottom of the image when they call, and this is due to the mismatch in the proportions of the photo and the screen, and the presence of a bang or notch under the camera, which the system tries to compensate for, and this can only be solved by the correct framing of the source.

Sometimes the problem is the theme, and if you use a third-party theme from MIUI Themes, it can force you to change the call interface, ignoring your photo settings, so try switching to the standard Classic or Unlimited theme to see if the black fields disappear.

⚠️ Note: Some "light" versions of Android (Go edition) or custom firmware may not support the full-screen photo of the caller due to the reduced functionality of the telephony.

Also, check the settings for Simplified Mode. If it's on, the call interface is simplified, and large, beautiful photos can be replaced with small icons. Turn off this mode in Settings → Advanced Settings → Simple Mode if you want to enjoy a quality picture.

FAQ: Frequently Asked Questions

💡

The quality of the picture display of the caller depends on 90% of the original resolution of the picture and the correct choice of the contact item when installing the wallpaper, not the phone model.

Using the built-in gallery tools and complying with the requirements for file formats, you can make using your smartphone more comfortable and enjoyable.
