Users of Xiaomi and Redmi smartphones often encounter an annoying feature of the MIUI interface and the new HyperOS shell. When an incoming call comes in, the system defaults to displaying the caller's photo as a small circle or square in the center of the screen, leaving the rest of the space filled with a blurred background or a standard placeholder. This not only looks unsightly, but also makes it difficult to quickly identify the caller, especially if you have many saved contacts with similar names.
Fortunately, this problem can be solved, although the standard phone settings often hide the necessary options. To contact photo occupy the entire display area during a call, you need to change the display settings in the “Phone” system application or use third-party utilities if the manufacturer has blocked this function in your firmware version. In this article, we will analyze in detail all the available methods for setting up full-screen mode for incoming calls.
Please note that the menu layout and item names may vary slightly depending on the version MIUI or HyperOSinstalled on your device. However, the general principle of operation of the system dialer remains the same for the entire ecosystem Android based on Redmi. If you want to personalize your gadget and remove the standard frames, follow the instructions below.
Standard settings of the Phone application in MIUI
First of all, you should check the built-in capabilities of the system application, since in the latest firmware updates Xiaomi has returned some of the customization functions. You don't need third-party apps if your software version supports the advanced call view. Go to the settings menu of the “Phone” application itself, which usually has a green icon with a handset on the main screen.
In the menu that opens, find the section responsible for the appearance of the interface. It may be called "Incoming Calls", "Call Screen" or "Display". Here you should look for the switch responsible for the photo display style. In some regions and firmware versions, this item is hidden inside the “Advanced” or “Advanced Settings” submenu.
If you find the “Full Screen Mode” or “Full Screen Photo” item, simply activate it. After this, the next time there is an incoming call, the system will try to stretch the contact image. However, there is an important nuance: for this function to work correctly, the original image in the contact must be of high resolution.
⚠️ Attention! In global firmware versions (Global ROM), some design features may be reduced compared to Chinese versions. If you don't find the switches you need, your regional software build may be limiting these options.
It's also worth checking to see if you have power saving mode enabled or specific skins that might force a change in the call screen style. Sometimes the active theme from the Mi Themes store locks the system settings for displaying avatars, returning them to the appearance set by the theme author.
Before changing the settings, make sure that you have the latest version of the Phone application installed through the Google Play Store or GetApps, as older versions may not support new features interface.
Contact image quality requirements
Even if you have configured the application correctly, the photo may look blurry or not fill the screen completely if the source file does not meet the technical requirements. The system Android and shell MIUI have restrictions on the minimum avatar resolution to activate full-screen mode.
Standard photos taken with the front camera in low resolution or downloaded from social networks in compressed form are often less than 500x500 pixels in size. For high-quality display on modern Redmi screens with FullHD+ resolution and higher, it is necessary to use images of much larger size.
It is recommended to use photographs with a resolution of at least 1080x1920 pixels (vertical orientation) or square images from 1000x1000 pixels. The system automatically crops the picture, but the higher the original quality, the clearer the subscriber's face will be when stretched across the entire display.
- 📸 Use original high-resolution photos, not screenshots from instant messengers.
- ✂️ Crop the image in a 9:16 aspect ratio before installation to avoid unsuccessful cropping system.
- 💾 Save photos in JPG or PNG format without strong compression to preserve details.
- 👤 Make sure the person's face is in the center of the frame, as the edges can be cut off by a round mask or interface elements.
To replace the photo, go to the Contacts application, select the one you want subscriber and click on the edit icon (pencil). There you will be able to upload a new image from the gallery. When selecting a photo, the system will offer to crop it - try to leave some space around your head so that when scaling, important details do not go off the edge of the screen.
Using third-party applications for calls
If the standard “Phone” application from Xiaomi does not allow you to enable full-screen mode or does not work correctly, the best solution would be to install an alternative dialer from the Google Play store. There are many applications that completely replace the system call interface, offering advanced personalization features.
One of the most popular and reliable solutions is an application Truecaller or specialized dialers like Call Screen - Phone Dialer. These apps have their own contact display engines, which ignore system restrictions and display the photo on the full screen, regardless of the version. Android.
After installing such an application, you must designate it as the default calling application. The system will ask you to confirm this action - agree that all incoming and outgoing calls will be processed through the new interface. In the settings of the application itself, there is usually a section “Theme” or “Ring Style”, where you can select the “Full Screen” mode.
| Application | Advantages | Disadvantages | Resource requirements |
|---|---|---|---|
| Truecaller | Qualifier numbers, spam blocking, themes | Intrusive advertising in the free version | Medium |
| Call Screen | Full customization, video calls | May conflict with system gestures | High |
| Phone Master | Lightweight, simple interface | Fewer customization functions | Low |
| System Dialer (Mod) | Preservation of native style, full screen | Requires manual APK installations | Low |
It is worth considering that third-party applications may consume more RAM and battery power than the system counterpart. In addition, some functions, such as call recording or integration with Xiaomi branded services, may not work correctly or require additional permissions.
Risk of using modified system applications
Installing modified versions of the “Phone” system application (mods) can lead to unstable operation of the device, loss of call history, or blocking by Google services. Use them only if you are an experienced user and understand the risks.
Customization through the Mi Themes design theme
Another way to change the appearance of the call screen without installing third-party dialers is to use custom themes in the official store Mi Themes. Many theme authors create designs where contact images are displayed in full screen by default, ignoring the standard MIUI restrictions.
Go to the Themes application on your Redmi. In the search bar, enter queries like “Full screen call”, “Big photo call” or “Full screen contacts”. Review the screenshots in the theme descriptions to make sure you are happy with the call screen style. Pay attention to the rating and the number of downloads - this will help you choose a stable product.
After downloading and applying the theme, check the call functionality. If the photo is still not full screen, go to the settings of the theme itself (usually a long tap on the theme icon in the “My Pages” → “Customize” menu). There you can often separately change the style of the lock screen and call screen without changing the desktop icons and wallpaper.
Some themes allow you to flexibly customize the size of your avatar. You can choose the position of the clock, answer buttons and, in fact, the scale of the photo. This makes it possible to create a unique interface that will be convenient for you and will solve the problem of a small image.
⚠️ Attention! When you change the theme, some widget settings and the arrangement of icons on the desktop may be reset. It is recommended to take a screenshot of the current location of applications before installing a new theme.
Specifics of working in the HyperOS shell
With the release of the new operating system HyperOS, which replaced MIUI, the algorithms for working with contacts and calls have undergone changes. In some builds of HyperOS, the full-screen photo setting is placed in a separate menu or combined with the Digital Well-being settings.
Redmi users with updated firmware should pay attention to the “Personalization” section in the general phone settings. There may be a “Call Screen Style” item that controls the global display of all calls. HyperOS also places an increased emphasis on integration with your Xiaomi account, so synchronizing contacts via Mi Cloud may affect which photo is pulled up during a call.
If the function is gone after updating to HyperOS, try clearing the cache of the Phone and Contacts applications. To do this, go to Settings → Applications → All applications, find the necessary services and select “Clear cache”. This action is safe and will not delete your data, but it can correct display errors that occurred after migrating the system.
In the HyperOS shell, priority is given to contacts synchronized via Mi Cloud. If the photo is not displayed on the entire screen, check whether the image is uploaded to the contact's cloud profile, and not just to the local phone memory.
Solving display problems and bugs
Sometimes, even if all the conditions are met, the photo does not stretch to the entire screen, but remains in the center with black margins or blur. This may be due to a specific bug in the firmware version or an access rights conflict. In such cases, a more in-depth diagnosis is required.
Check whether Do Not Disturb mode or specific audio profiles are enabled, which may simplify the call interface to save resources. It's also worth disabling any "Simplified Mode" or Senior Mode options, which often force changes in the size of interface elements.
If the problem persists only for certain contacts, delete them from the phone book and create again, immediately assigning a high-quality photo. Old entries in the contact database may contain links to outdated thumbnails, which the system caches and does not update even when the image is replaced.
- 🔄 Restart your smartphone after all settings changes - this often solves problems with applying new interface settings.
- 🗑️ Delete and re-add the problematic contact to update its entry in the database data.
- 📵 Check the operation in safe mode: if there is a photo in it on the whole screen, then a third-party application is to blame.
As a last resort, if nothing helps, you can reset the system application settings. This will return all system apps (Phone, Contacts, Messages) to the factory state. Your personal data (photos, contacts) will not be affected, but the settings for calls, vibration feedback and sorting will be reset.
☑️ Diagnosing a problem with a photo
Why is the contact photo cut off at the edges even in full screen mode?
This is due to the different aspect ratio of your smartphone screen and the original image. The screens of modern Redmi have an aspect ratio of 19.5:9 or 20:9, and most photos are 4:3 or 16:9. The system automatically crops the image to fill the screen without black bars, sacrificing the edges of the picture. To avoid this, use photos that have been pre-cropped to fit the screen format of your device.
Is it possible to put a video instead of a photo when making a call on Redmi?
You cannot set a video to an incoming call using standard MIUI and HyperOS tools. To do this, you will need to install special applications from Google Play, such as “Video Caller” or analogues. They work on the principle of overlaying a video layer on top of the call screen, but can consume a significant amount of battery.
Are photo settings reset when updating the Android system?
Usually no. When updating the firmware over the air (OTA), user data and contact settings are preserved. However, if you perform a full device reset (Wipe Data) or switch from one version of Android to another with a clean installation, all settings will have to be configured again, including uploading photos.
Why do some contacts have full-screen photos, while others do not?
The most common reason is the quality of the saved image. For some contacts you could upload a high-resolution photo from the gallery, while for others you could use a low-quality avatar from a messenger or social network. The system automatically applies full-screen mode only to images exceeding a certain resolution threshold.
Does saving energy affect the display of photos during a call?
Yes, in strict energy saving mode, the system can simplify animations and interface graphics to extend operating time. This may result in the full-screen photo being replaced with a standard icon or reduced in size. Disable the power saving mode to check whether the correct display is restored.
