Modern smartphones like the Xiaomi Redmi Note 8 Pro offer users many options for personalizing the interface, turning standard features into a unique experience. One of the most popular settings is to install a full-screen photo of a subscriber during an incoming call, which allows you to instantly recognize the caller without having to look at miniature icons. However, the standard interface of the MIUI shell on which the device’s operating system is based does not always provide this option out of the box in a familiar way, requiring the user to perform certain actions or use specialized tools.
Owners of the Redmi Note 8 Pro often find themselves in a situation where, after adding an image to their contacts, it appears only as a small circle in the corner of the display, occupying only a small part of the usable area. This limitation is dictated by the design and logic of the standard Google Phone application or MIUI system caller, whose priority is to display important information about the call, rather than visual effects. However, the desire to see the face of the interlocutor on the full screen is justified, especially for people with impaired vision or just for aesthetic pleasure.
In this guide, we will discuss in detail all the available ways to solve this problem, from built-in system functions to the use of third-party applications that guarantee the implementation of the Full Screen Caller ID function. We will look at the nuances of working with access rights, permission settings and possible version conflicts so that you can enjoy personalized calls without unnecessary difficulties. Understanding the principles of the notification system and contact management in Android will help you not only solve the current problem, but also more deeply customize your device for your own needs.
Features of displaying contacts in MIUI
The MIUI shell on the Redmi Note 8 Pro has its own unique architecture for multimedia content and contacts. Unlike pure Android, it tightens the access of applications to system calls, which often leads to a restriction of functionality by standard means. When you add a photo to contact through a standard Caller or Contacts app, the system automatically frames the image into a circle, ignoring the proportions of the screen, which creates the effect of a small photo.
The problem is that the standard incoming call interface is not designed to stretch images across the entire display matrix without using special zoom algorithms. Your smartphone screen resolution is 1080x2340 pixels, and the standard application simply cannot fill this area with the picture from the address book by default. This is done to keep the interface concise, but for many users becomes a limitation.
⚠️ Warning: Attempts to change system call files without having superuser (Root) rights can lead to unstable device operation or a cyclic bootloop. Use only secure customization methods through the user interface or proven applications.
In addition, it is important to consider the version of MIUI installed on your Redmi Note 8 Pro. In newer versions (MIUI 12, 13 and above), the security policy has been tightened, and access to the call background for third-party applications can be limited by default.So even installing specialized software will require you to carefully adjust permissions, as will be discussed below.
Use of built-in Google Contacts features
The first step to take is to test the capabilities of Google’s standard app, which is often pre-installed alongside Xiaomi’s system counterparts.The Google Contacts app has more flexible sync and display settings, although it doesn’t always guarantee full-screen mode without additional utilities. However, properly formatting the image in the contact itself can improve things.
First, make sure the photo is of high quality and the right proportions. The ideal option is a square image or portrait with an aspect ratio close to the vertical screen of the smartphone. Upload the photo in the maximum available resolution so that no detail is lost when zooming. System algorithms often compress images, so the source must be of quality.
The process of adding or replacing photos through Google Contacts is as follows:
- 📸 Open the Contacts app (an icon with a person’s silhouette) on the home screen or menu.
- 👤 Find the right subscriber in the list or use the search bar at the top of the screen.
- ✏️ Click the Change button (usually a pencil icon), then tap the current photo or the place to add it.
- 💾 Select an image from the gallery, edit the framing and save the changes.
After saving the changes, the system may require time to sync with Google’s cloud storage. If the photo does not appear immediately, try rebooting the device or forcefully updating the contact list. It is worth noting that even after these manipulations on the Redmi Note 8 Pro, the photo may remain in a round window, since this is the restriction of the incoming call interface, not the data storage.
Application of third-party applications for Caller ID
The most effective and guaranteed way to get a full-screen photo is to use specialized applications designed for this purpose, such as intercepting incoming calls and displaying your own window on top of the system, filling the entire display with an image from your phone book. For Xiaomi Redmi Note 8 Pro, applications like Caller ID & Screen, Truecaller or Full Screen Caller ID are great.
Once you install an app like this from Google Play, you need to give it a wide range of permissions, which is critical because without access to your phone, contacts, and most importantly, the rights to “display on top of other apps,” the program will not work. In modern versions of Android, these permissions are not automatically granted, they need to be manually activated in settings.
Let’s look at the main advantages of using third-party solutions:
- 🖼️ Full use of screen area with the ability to adjust frames and effects.
- ⚙️ Flexible configuration of information display: you can add a name, number, reset or response button.
- 🎨 Support for design themes, animations and different styles of the call interface.
However, it should be remembered that such applications consume additional battery power, as they must constantly monitor the status of incoming calls. In addition, they can conflict with the system call if the settings are not correct. On the Redmi Note 8 Pro with its powerful Helio G90T processor, the load will be minimal, but the battery optimization in MIUI can try to “kill” the call process in the background.
⚠️ Attention: When installing applications for Caller ID from unreliable sources, you risk giving access to your phone book to third parties. Use only proven high-ranking programs in the official Google Play store.
Setup of permissions and auto-runs in MIUI
Owners of the Xiaomi Redmi Note 8 Pro are familiar with the aggressive MIUI energy saving system, which by default limits the background activity of applications. To make a third-party call or even an improved version of the standard one work stably and show a photo to the full screen, you need to exclude it from the list of “sleeping” processes. Without this step, after unlocking the screen or at the time of the call, you can see a black screen or a standard system instead of a photo.
First of all, you need to set up autorun. Find the installed application for calls in the settings menu or through the search in Settings, go to Autostart and activate the switch. This will allow the program to start with the system and be ready to intercept the call at any time. Next, you should allow mapping over other windows.
The sequence of actions to configure access rights:
- Go to Settings → Applications → All applications.
- Find your call app (like Calls or Truecaller) in the list.
- Select Other permissions and enable Display on top of other applications.
- In the Activity Control section, select No Limits.
It is also important to lock the app into memory if you often multitask. Open the menu of running apps, find the call window, pull it down before the lock appears and click on it. This will prevent the program from accidentally closing when cleaning up memory. On the Redmi Note 8 Pro, the amount of RAM allows you to keep many applications active, but the system can still clean the background processes when resources are scarce.

Compatibility table and comparison of methods
To make it easier for you to choose the right method for personalizing calls on the Xiaomi Redmi Note 8 Pro, we have prepared a comparison table that will help you assess the pros and cons of each approach, taking into account your priorities: stability, functionality or battery retention.
| Method | Difficulty setting up | Impact on the battery | Stability of work | Image quality |
|---|---|---|---|---|
| Standard Contacts | Low. | Minimum | Tall. | Just a thumbnail. |
| Google Contacts | Low. | Minimum | Tall. | Just a thumbnail. |
| Third-party applications (Caller ID) | Medium | Average. | Depends on the settings. | Full screen |
| Design themes (Themes) | Tall. | Average. | Medium | Depends on the topic. |
As you can see from the table, the only way to get a full-screen photo is to use third-party apps or specific themes. Standard tools, unfortunately, limit the user to a round avatar. If you are critical to autonomy, you need a full-screen photo, because the constant monitoring of calls with third-party software consumes energy.
Themes can change the call interface, but they often require changing the entire visual shell of the system, which may not appeal to users who are used to the standard MIUI. In addition, the themes may stop working correctly after updating the system, while individual applications are more independent of the firmware versions.
Why can’t the photo be displayed even after setting up?
Frequent problems and ways to solve them
When setting up a full-screen photo on the Redmi Note 8 Pro, users may encounter a number of typical problems, most often related to the operation of the Android operating system in conjunction with the MIUI shell. Understanding the causes of these failures will help quickly return functionality to working condition without the need to reset settings.
One common problem is contact desynchronization, and once the system or the call app is updated, access to the address book may be temporarily lost, permissions may need to be re-executed, and the image may be “flying” when the theme is changed, as the new visual style may not support the enhanced Caller ID features.
Another important aspect is the format and size of the image file: Too heavy photos (for example, 48 MP shots taken by the main camera of the Redmi Note 8 Pro) can be processed for a long time or cause delays when the call screen appears.
💡
For better performance, use photos no larger than 1080x1920 pixels. This corresponds to the native screen resolution of your smartphone and will not put unnecessary strain on the processor when rendering the image during an incoming call.
If the caller app stops showing a photo, try deleting it and installing it again, after clearing the old instance data. Sometimes configuration files accumulate errors that prevent the graphics from being displayed correctly. Also make sure that the battery settings do not have the "Saving Energy" limit for that particular application.
⚠️ WARNING: When using themes from unofficial sources or modified versions of applications, you may violate the integrity of the security system. MIUI, This will result in blocking some of Google Pay’s banking applications or services.
Outcome recommendations and conclusions
Set up a full-screen photo contact on the Xiaomi Redmi Note 8 Pro is a solvable task, but it requires going beyond the standard settings. If you are happy with a small round avatar, just add a photo to the contact through a standard application. However, for a full visual experience, you will need to install additional software and carefully adjust the access rights in the system.
The main obstacle remains the aggressive battery optimization in MIUI, which seeks to close any background application.The key to success lies in a competent autorun and permission configuration. Don't neglect to check these parameters after each major system update, as resets of security settings can return default limitations.
💡
Installing a third-party Caller ID app and properly configuring MIUI access rights is the only guaranteed way to get a full-screen photo on the Redmi Note 8 Pro.
Use high-quality but optimized images to keep the system from overloading. Keep an eye out for app updates as developers are constantly improving compatibility with new versions of Android. Personalizing your smartphone is not just a matter of aesthetics, but a way to make using your device more user-friendly and intuitive.
