Modern smartphones have become an integral part of our lives, and device personalization comes to the fore. One of the most pleasant visual improvements is the ability to see the caller's photo in full screen during an incoming call. This is not only aesthetically pleasing, but also helps the caller instantly without having to look at the small icon in the corner of the display. However, the ability to implement this function directly depends on the version of the operating system Android and the manufacturer's shell.
In the latest versions of the system, Google has significantly changed its approach to displaying contacts. If previously it was enough to simply select an image in the phone book, now priority algorithms work differently. The standard interface often reduces the avatar to a small circle, overlaid with a name and call control buttons. To bypass these limitations and return a full-fledged image, the user needs to know several technical nuances and configuration secrets.
In this article we will look in detail at how to activate full-screen mode for the caller's photo on various smartphone models. We will look at the differences in the operation of pure shells, shells from Samsung and shells from Xiaomi. We will also pay attention to image quality requirements and third-party solutions that can help if standard methods do not work. Get ready to turn your boring call screen into a personalized gallery. Android, shells One UI from Samsung and MIUI from Xiaomi. We will also pay attention to image quality requirements and third-party solutions that can help if standard methods do not work. Get ready to transform your boring call screen into a personalized gallery.
Image and file format requirements
Before you begin customization, it is critical to prepare the correct source file. The system will not stretch a small picture to fit the screen without losing quality, turning the subscriber’s face into a set of pixels. For correct display on modern high-resolution displays, it is necessary to use photographs of a certain size and proportions.
The ideal option is a vertical image with an aspect ratio 9:16. These are the proportions that correspond to most smartphone screens in portrait orientation. If you try to set a horizontal photo or a square photo, the system will automatically crop the edges or add black margins, ruining the visual effect. The resolution of the picture must be at least 1080×1920 pixels, and for devices with QHD+ screens it is better to look for sources in 1440×2560.
Pay attention to the file format. Although Android supports many types of graphics, the JPG i PNGformats work most stably. The PNG format is preferable if you want to use an image with a transparent background, although the standard dialer interface often replaces transparency with black or a blurred color. Avoid heavy files larger than 5-10 MB, as this may slightly increase the contact loading time for an incoming call.
⚠️ Attention: Avoid using images with watermarks or text around the edges. When you call, the phone interface will overlay its controls (answer buttons, name, timer) on top of the photo, and the text will become unreadable.
Use photo editing applications to pre-crop the photo to a 9:16 ratio and sharpen it before installing it in contacts.
Setting in pure Android and Google Contacts
In smartphones with a clean operating system or minimal modifications (for example, series Google Pixel, Motorola, Nokia), contacts are managed through the app Google Contacts. Here the operating logic is quite simple, but it has its limitations related to account synchronization.
To install a photo, you need to open the contacts application and find the desired subscriber. After going to the user card, click on the edit icon (usually a pencil icon). At the top of the screen you will see the current image or an empty circle. Clicking on this area will open the source selection menu: you can take a new photo through the camera or select an existing one from Gallery.
After selecting an image, the system will offer to crop it. This is the key: you need to position the frame so that the face takes up the central part, but still leaves some margin around the edges. The fact is that in some versions of the shell the dialer interface may slightly overlap the edges of the avatar. Confirm your choice with the button Save or Done.
- 📸 Make sure that the contact is saved in your Google account and not in your phone memory or SIM card, since photo synchronization works best with the cloud.
- 🔄 After saving, restart the "Phone" application so that the changes are applied to the incoming call interface.
- 👤 Check if the contact is duplicated: having two entries with the same number can lead to a display conflict.
It is worth noting that in the latest interface updates Google Phone the company experiments with design. In some regions and on certain software versions, the photo may not be displayed on the entire screen, but as a large circle on a blurred background. This behavior is hard-coded by developers and cannot always be changed using standard means.
Samsung One interface features UI
Corporation smartphones Samsung use a shell One UIwhich has its own logic for displaying calls. The situation here is twofold: on the one hand, the interface is very flexible, on the other hand, in the latest versions (starting with One UI 5 and 6), Samsung has introduced a style where the photo is often located at the top of the screen, and not stretched into the background.
To adapt the display as much as possible, go to the application Phone and click on the three dots in the corner to call up the menu. Select item Settings, and then find section Type of calls and spam or simply Call subject. In some models, the "Full Screen Contact" option is available, but it may be hidden or depend on the firmware version.
If It is not possible to achieve the desired effect with standard settings; you can try a trick with a design theme. The store Galaxy Store offers thousands of themes, some of which change the lock screen and call screen. Installing a specialized theme can forcefully change the layout of the dialer interface, returning the photo to the background.
| One UI version | Photo display type | Can be changed |
|---|---|---|
| One UI 3.0 - 4.0 | Partial background / Large circle | High (via themes) |
| One UI 5.0 - 5.1 | Circle at the top + Blurred background | Medium (system limited) |
| One UI 6.0+ | Material design (circle) | Low (requires third-party launchers) |
Users of the flagship models of the series S i Z often note that after major software updates, the visualization settings are reset. Therefore, if you have lost the beautiful display after the update, check the settings of the dialer themes and widgets again.
Specific settings in Xiaomi (MIUI and HyperOS)
Shells from Xiaomi are known for their deep customization, but there are pitfalls here too. In MIUI and the new HyperOS Phone application can be either its own or from Google (in global versions). This radically changes the approach to setup.
If you have a native MIUI dialer, go to Settings Phone applications. Find item Incoming calls. There is often a “Show contact photo” switch or style settings here. Some firmware versions have a separate menu “Contact Themes”, which allows you to upload your own images for groups of subscribers.
For global versions with the Google application, the actions are similar to pure Android, described above. However, Xiaomi users often encounter a problem when the photo is displayed only when the screen is unlocked, and the standard icon remains on the lock screen. This is due to security and energy saving settings.
Secret code for resetting the dialer settings
In some versions of MIUI, resetting the Phone application settings via code ##4636## can return the standard photo display if a failure occurred after the update.
It is recommended to check the permissions for the Contacts application. Go to Phone settings → Applications → Application management → Contacts → Access rights. Make sure that storage access and display on top of other applications are allowed. Without this, the system may block the loading of heavy images to the lock screen.
Using third-party applications for customization
When the built-in system tools do not allow you to implement your plans, third-party ones come to the rescue solutions from the store Google Play. There is a whole class of applications that replace the standard incoming call screen with their own, more functional and beautiful.
One of the most popular solutions is the application Calls Blacklist or specialized call screen launchers, such as True Phone Dialer & Contacts. These apps intercept an incoming call and display it in their interface, where you can set the photo to fill the entire screen without any restrictions from the smartphone manufacturer.
Installation of such software requires advanced rights. You will need to set the new app as your default calling app. After this, with each incoming call the interface of the selected app will open. This makes it possible not only to put a photo, but also to add widgets, change the color of buttons and the background.
⚠️ Attention: Third-party dialers may consume more battery power, since they work in the background constantly. In addition, on some smartphones with aggressive optimization (for example, Xiaomi or Huawei), the system will need to be manually added to the exclusion list to save energy.

Solving problems with display and synchronization
Even with correct settings, users may encounter a situation where the photo is not displayed or shown incorrect. Most often, the reason lies in the application cache or a synchronization conflict between the local database and the cloud. First, try clearing the application cache. Go to
First of all, try clearing the application cache Contact And Phone. Go to Settings → Applications, find the apps you need and select Storage → Clear cache. Do not confuse this with clearing data, as deleting data can erase call history, although contacts are usually restored from the cloud.
If the problem persists, check the synchronization format. Go to your Google account settings on your phone and make sure the checkbox next to Contact is active. Try to force synchronize the data: click on the three dots in the account menu and select Synchronize.
- 🗑️ Delete the contact and create it again, immediately adding a high-quality photo - this often solves the problem of “broken” links to the image.
- 📶 Check your Internet connection: if the photo is stored in in the cloud, loading it onto the call screen may require short-term access to the network.
- 📱 Reboot the device: a simple restart often clears temporary graphical interface bugs.
In rare cases, the problem may be in the picture itself. Try converting the image to another format or resizing it slightly in a graphics editor. Sometimes the system does not recognize specific color profiles (for example, CMYK instead of RGB) in JPG files.
If the photo does not appear after all the manipulations, most likely the blocking comes from the system theme - try resetting the theme to the standard one.
Frequently asked questions (FAQ)
Why is the caller's photo is displayed only in a small circle, although the picture is large?
This is a design limitation of a specific version of the interface (shell) of your smartphone. Manufacturers such as Samsung or Google in new versions of Android intentionally make the avatar smaller to make room for control buttons and spam information. The only way to get around this is by changing the theme or installing a third-party dialer.
Is it possible to put a video instead of a photo when making a call?
You cannot put a full-screen video on the full screen when making a call using standard Android tools. However, some manufacturers (for example, Xiaomi or OPPO) have a built-in “Video call” or “Video contact” function that plays a short video. In other cases, you will need third-party applications from Google Play that support this function.
The photo disappears after rebooting the phone, what is the reason?
Most likely, the contact is not saved in your Google account, but in the phone’s local storage or on a SIM card that does not support storing high-resolution images. Transfer the contact to your Google account: open the contact, select "Edit" and change the save field to your Gmail account.
How to take different photos for the same number from different SIM cards?
Unfortunately, in the standard phone book, the link is to the phone number, and not to the SIM card. If the number is the same, the system will show the same photo regardless of which SIM card the call came to. A solution could be to save the number with different names (for example, “Mom Sim1”, “Mom Sim2”), but this is inconvenient for dialing.
