Modern Xiaomi smartphones, particularly the popular Redmi Note 8 Pro, offer users a wide range of personalization options. One of the most popular requests among owners of these devices is the desire to install a high-quality subscriber image on the entire display during an incoming call. Standard system settings often limit the avatar to a small round window, which does not allow you to fully enjoy the detail of the photo.
However, the MIUI operating system that runs the device hides several effective ways to get around these limitations: Redmi Note 8 Pro owners can use both built-in gallery tools and third-party apps from the Google Play store. Understanding the nuances of working with image resolutions and file formats will allow you to create a truly unique visual experience when making calls.
In this article, we will take a look at all the methods available, from simple contact actions to advanced file manager settings. You will learn why a standard crop tool may not be able to do the job and how to properly prepare the image in advance. This guide will help you maximize the potential of your smartphone screen.
Preparation of images for high-quality display
Before you try to install a full-screen photo, it is critical to properly prepare the source file.The Redmi Note 8 Pro screen has a resolution of 2340×1080 pixels and an aspect ratio of 19.5:9. If you upload a square photo or a picture with a proportion of 4:3, the system will automatically crop it or leave black fields, which will spoil the impression.
The ideal solution is to pre-fracture the photo in a vertical format as close as possible to the proportions of the display, which can be done using any built-in gallery editor or specialized applications, and make sure that the quality of the source is high, because stretching a small picture to the full screen will lead to "grain" and compression artifacts.
💡
Use photos in vertical orientation (portrait mode) – they occupy the maximum screen area during a call, as opposed to horizontal shots.
Also worth paying attention to is the weight of the file: too heavy images in RAW or uncompressed PNG can be processed by the system for longer when you call in, the optimal choice is the JPEG format with high compression quality, which will ensure that the image loads quickly at the time of the call without delay.
- 📐 The aspect ratio of the image should be vertical, preferably 9:16 or 9:19.5.
- 🖼️ The photo resolution should be at least 1080×2340 pixel.
- 💾 Optimal file format — JPG/JPEG processor-wise.
- 🎨 Avoid important details around the edges of the frame, as interface elements may overlap them.
Standard method through the Contacts app
The easiest way for everyone to use the Xiaomi Redmi Note 8 Pro without installing additional software is to use the phonebook’s built-in functionality. Although this method often limits the display area, the right sequence of steps can give an acceptable result.
To start, you need to open the Contacts app or Phone app and find the right subscriber in the list. After you go to the contact page, click on the edit button, which is usually indicated by a pencil or an Change icon. At the top of the screen you will see the current avatar or silhouette of the person — this is where you need to click to add a photo.
☑️ Installation algorithm through contacts
The system will ask you to select an image from a gallery or take a picture with a camera. After selecting a file, the framing interface will open. Here it is important to understand that the standard tool often offers only round trimming. To get the image as close as possible to full-screen mode, use "picks" to zoom in inside the circle, filling the accessible area with facial details.
⚠️ Attention: Standard shell contact app MIUI It often forcibly cuts a photo into a circle, even if you chose a rectangular image. For full-screen effect, this method may not be enough, and you will need to use third-party solutions described below.
Once you're satisfied with the cropping results, press the save button. Now, when you call in from that caller, you'll see the image that's set, but if you want the photo to cover the entire screen, including the area above the caller's name, you'll have to use more advanced methods.
Use of third-party applications for Caller ID
To implement the full-screen photo feature on the Redmi Note 8 Pro, the most effective solution is to install specialized applications from the Google Play store. Programs like Truecaller, Whoscall or specific "Full Screen Caller ID" create a layer on top of the standard call interface that can display any image without form restrictions.
Once you install an app, you'll need to give it a number of permissions, first of all, access to contacts and a phone book so that the program can identify the caller; second, permission to display on top of other applications is critical, and without that, the program won't be able to block Xiaomi's standard bell ringer with its interface.
The settings of these apps are usually intuitive. In the program menu, you select a Style that you can specify that the photo should be full screen (Full Screen). Then, in the settings of the photo sources, select a gallery. Some applications even allow you to create groups of contacts with the same background images, which is very convenient for the organization.
- 📲 Download the full screen caller app ID" Play Market.
- 🔐 Permit access to contacts and phone at first launch.
- 🖥️ Activate “Display over other apps” in Android settings.
- 🎨 Upload your photos to the app database or link them to contacts.
Configure permissions and access to MIUI
MIUI is known for its strict security policy, which can block third-party number detectors. On the Redmi Note 8 Pro, you need to manually check multiple access levels after installing the full-screen photo app, otherwise the feature will not work.
Go to Settings → Applications → All apps. Find the Caller ID you have installed. Go to Other Permissions (or simply “Allowances”). You need to activate all items, especially those relating to access to memory and phone. If you see “Start”, it is also better to turn it on so that the system does not “kill” the process in the background.
The path to permission settings:
Settings → Applications → All Apps → [Your App] → Permissions → Enable AllThe system can limit the background activity of the application to save the battery of the Redmi Note 8 Pro. In the application settings, find Battery or Energy Saving and select No Limits mode. This ensures that when you call in, the system does not block the launch of the full-screen image.
⚠️ Warning: If after all the settings, the photo still does not appear, try to restart the smartphone. MIUI Changes in access rights and auto-start often only take effect after a full cycle of switching off and on the device.
Comparison of methods of installation of avatars
To make it easier for you to choose the right option for your Redmi Note 8 Pro, we have prepared a comparison table that shows the differences between the standard method and the use of third-party software in key parameters.
| Parameter | Standard contacts | Third-party annexes |
|---|---|---|
| Photo form | Just a circle or a square. | Any, including the full screen |
| Display quality | Depends on the system crop | Maximum, no pruning. |
| Battery consumption | Minimum | Average (works in the background) |
| Difficulty setting up | Low (2-3 clicks) | Medium (requires access rights) |
| Stability | 100% (system function) | Depends on the MIUI version. |
As you can see from the table, the standard method wins in simplicity and resource savings, but loses in the visual component. If it is the wow effect and the maximum filling of screen space with high-quality photos that is important to you, then installing additional software is no alternative.
It’s also worth noting that third-party apps often have their own number databases, allowing you to see photos of even those subscribers who aren’t in your notebook, an additional feature that can be useful for filtering spam and unknown calls.
Problem Solving and Troubleshooting
Owners of Xiaomi Redmi Note 8 Pro may face a situation where, despite all the settings, the photo is displayed incorrectly or does not appear at all. Often the problem lies in the cache of the Contacts or Phone app. Clearing the cache can solve the problem of incorrect display of avatars.
To do this, go to Settings → Apps → All apps, find Contacts and Phone. Select Memory and click Clear Cache. Don't confuse it with Clear All Data, otherwise you may lose your call history, although contacts are usually synchronized with your account.
What to do if the photo is “floating” or shifting?
Another common problem is the design conflict: If you use a third-party theme from Themes, it can force you to set your call display style by ignoring your photo settings, in which case you can try temporarily switching to a standard Classic or Default theme to see if the full-screen effect will continue.
- 🧹 Clear the cache of the "Phone" and "Contacts" applications through the settings.
- 🔄 Check if the antivirus or optimizer is blocking Caller. ID.
- 🎨 Temporarily change the theme of registration to the standard for checking the conflict.
- 📸 Make sure the original photo is not damaged and opens in the gallery.
💡
The main secret of success on the Redmi Note 8 Pro is the combination of properly cropped vertical photos and permissions to “display on top of other applications” for third-party software.
