Modern smartphones, especially flagships and mid-segment models from the South Korean giant, are equipped with magnificent displays with minimal bezels. However, owners often face an annoying problem: when they receive an incoming call, instead of a spectacular portrait of the subscriber on the entire display, they see only a small image in a round frame or a standard blank. This is especially annoying, since visual identification of the caller is one of the basic comfort functions.
The reason for this behavior lies not in hardware limitations, but in the logic of the standard application Samsung Phone and system interface settings One UI. The operating system Android in the Samsung shell by default prioritizes the compact display mode so as not to overlap important information or widgets. Fortunately, this situation can be corrected by returning the full-screen mode for displaying contacts, which was familiar to users in earlier firmware versions.
In this material we will analyze in detail all the available ways to solve the problem. We will consider both standard system settings and the use of third-party utilities if the built-in methods for some reason do not work on your model. You will learn why the photo is cropped and how to properly prepare the image for ideal display.
Why the caller's photo is not displayed on the entire screen
Before proceeding with the settings, it is important to understand the technical side of the issue. The interface One UI is designed with ergonomics in mind: the main controls are located in the lower third of the screen so that they are easy to reach with your thumb. In the latest firmware updates, the developers deliberately changed the style of displaying incoming calls, making the contact avatar smaller.
This change was dictated by the desire to unify the design and add additional buttons to answer or reject a call without overlapping the image. However, for many users, the aesthetic component and the ability to immediately see the caller’s face in high resolution are more important than ergonomic innovations. The system takes a standard square photo from a gallery and automatically crops it into a circle, often cropping out important details.
In addition, the resolution of the source image plays a critical role. If you have installed a low-quality picture, the system may not stretch it to fill the entire screen to avoid the appearance of “grain” or pixelation. High resolution source is a guarantee that the system will allow you to use it as a full-screen call screensaver.
⚠️ Attention: On some models series Galaxy A and M with a simplified version of the shell, restrictions on the size of the displayed photo may be stricter than on the flagship series S or Z.
Setting through the standard Contacts application
The most obvious and often working method is to reassign the photo directly in the card subscriber The standard application Contact on Samsung has a built-in editor that allows you not only to select a file, but also to trim it to the desired format. However, many users skip the editing step, which is why the photo is inserted incorrectly.
First, open the application Contact and find the desired subscriber in the list. Click on his name to open a detailed card. In the upper right corner or next to your current profile picture, you will see a pencil icon or button Edit. Clicking on it will put the card into editing mode.
Next, click on the current avatar or camera icon. The system will prompt you to select a source: take a new photo or select from the gallery. When selecting from a gallery, it is critical to use the crop tool. A frame will appear, which may be square by default. You need to change its shape or simply stretch the selection area so that the face occupies the maximum area.
- 📸 Choose vertical photos, since the smartphone screen is oriented portrait.
- ✂️ Use the “Crop” tool to remove excess edges before saving.
- 💾 Be sure to click button
Savein the upper corner after all manipulations.
After saving, the system will update the contact cache. Try calling this person from a different number or ask him to dial you to check the result. If the photo still seems small, move on to the next method, which affects the global theme settings.
Use photos with a resolution of at least 1080x1920 pixels. This is the native resolution of most Samsung screens, which guarantees clear images without stretching.
Changing the theme of the lock screen and calls
In the shell One UI the appearance of the call screen is closely related to the active theme. Some third-party themes downloaded from the store Galaxy Storemay force you to set your call display style, ignoring system preferences. Returning to the standard theme often solves the problem of a small photo.
Go to Settings your device and scroll through the menu to Wallpaper and style (or simply Themes depending on the Android version). Here you will see a list of installed themes. Make sure that the topic Default or Systemis selected. If any downloaded theme is active, apply the standard one and check the incoming call.
Also in this section you should pay attention to the style settings icons and flowers. New firmware versions have a function Color palettethat adjusts the interface to the wallpaper. Sometimes turning this option on or off reloads the graphical resources of the dialer interface, returning full-screen mode.
| Parameter | Recommended value | Impact on photo |
|---|---|---|
| Theme | Default | Guarantees a standard full-screen view |
| Font size | Standard or Small | The font may be too large compress photo area |
| Screen enlargement | Default | Zoom mode can crop the edges of the image |
| Simple mode | Off | In simple mode, the call interface is simplified and photo less |
Pay attention to the “Simple mode” item in the table. When enabled, the interface adjusts to accommodate visually impaired users by increasing the controls and decreasing the decorative elements, which include the caller's photo. Disabling this mode in Settings Display can instantly solve your problem.

Using third-party applications for calls
If standard Samsung tools do not allow you to achieve the desired effect, specialized applications from Samsung come to the rescue store Google Play. These utilities completely replace the standard incoming call interface, offering advanced customization features, including background blur, animation and, of course, full-screen photos. One of the most popular solutions is an application or specialized “Call Screens”. After installing such an application, you will need to grant it permissions to access contacts, phone, and display on top of other windows. Without the last permission, the application will not be able to intercept the moment of an incoming call.
One of the most popular solutions is the application Truecaller or specialized “Call Screens”. After installing such an application, you will need to grant it permissions to access contacts, phone, and display on top of other windows. Without the last permission, the application will not be able to intercept the moment of an incoming call.
In the settings of such applications there is usually a separate section Call theme or Call Background. Here you can upload your image and select the display mode Full Screen or Fill. The advantage of third-party solutions is that they often ignore One UI system limitations and stretch the picture regardless of the Android version.
⚠️ Attention: Third-party calling applications require permanent permissions to run in the background, which may slightly increase battery consumption. Also make sure that the application has a high rating to avoid spam.
It is worth considering that when using a third-party dialer, you may lose integration with some proprietary Samsung features, for example, quick call recording (if supported in your region) or number identification through the operator's database. Weigh the pros and cons before installing.
Why may third-party applications not work?
On Android 10 and higher, Google has tightened the rules for accessing the phone. Some caller applications may be unstable or require complex configuration through accessibility features.
Cache problems and resetting the Phone application settings
Sometimes the problem is software in nature and is associated with accumulated garbage in the system application cache. If you changed the photo, but it was not updated, or the call interface is stuck in the old style, you will need to clear the application data Phone.
Don't worry, this procedure will not delete your contacts or call history, as they are stored in a separate storage Contact and on the SIM card. However, dialing settings will be reset, for example, blocking unwanted numbers or recording conversations if they were activated.
To clear, go to Settings → Applications. Find the application Phone in the list (it has a green icon with a handset). Click on the item Memory or Storage, and then select the button Clear cache. If this does not help, click Clear data.
After this manipulation, reboot the device. On the first call, the system will re-create the interface, pulling up the latest data from the contacts. Often this step returns full-screen mode if it was disabled after a firmware update.
- 🔄 Reboot is required after clearing system application data.
- 📞 Check the operation on different contacts, not just one.
- ⚙️ Don't forget to set up the lock again spam if it was enabled.
Clearing Phone application data is a safe procedure for contacts, but it resets the blocking and call recording settings.
Display features on different versions of One UI
Users should understand that the Samsung interface is constantly evolving. What worked on One UI 3.1may look different on One UI 6.0. In the latest versions of Android, the company relies on minimalism, so the ability to completely remove the round frame around the photo may be limited at the software level.
On some models, especially those released in 2023-2026, the caller's photo is displayed in a circle by default, but the background around it is blurred and stretched across the entire screen, creating the effect of depth. This is a compromise decision by the designers. It becomes increasingly difficult to completely remove the circle, leaving only a “naked” photo, in stock firmware without root access.
However, the use of high-quality vertical wallpaper in VKontakte helps the system understand that it needs to use the entire display space for the background. If you set a square photo, the system will compress it. If it is vertical, it will take up more space.
⚠️ Attention: Mobile operating system interfaces are updated regularly. If the described menu items do not match your screen, use the settings search by entering the query “Themes” or “Contacts.”
Try to set the contact photo not to a portrait, but to a beautiful landscape or abstraction in a vertical format. Often, the system more willingly stretches such images across the entire background than people’s faces.
Frequently asked questions (FAQ)
Why did the caller’s photo become small after updating Android?
Samsung developers in new versions of One UI changed the design of the call screen, focusing on control buttons and number information, reducing This is the area for your avatar. This is a global style change that cannot be rolled back with a simple setting, but can be circumvented by changing the theme or using third-party applications.
Is it possible to make a video instead of a photo when making a call on Samsung?
By standard means, the standard “Phone” application does not support video playback for an incoming call. To do this, you need to install special applications from Google Play, for example, “Video dialer” or analogues that replace the call lock screen with a video player.
Why is the photo displayed in full screen only when the phone is unlocked?
This is a security and privacy setting. On the lock screen, the system shows a simplified interface to protect your data. A full photo with details is often shown only after you swipe to respond or if the phone is already unlocked. Check the lock screen settings in the “Wallpaper and style” section.
How to return the old call design as on Android 9?
It is impossible to return the old design using system tools, since the interface files are replaced when updating the firmware. The only way to get a retro design is to use third-party launchers or calling applications that emulate the old style of displaying contacts.
Does the photo format (JPG or PNG) affect the display?
The file format is not critical for display, what is more important is its resolution and proportions. However, a PNG with a transparent background may not display correctly if the system does not handle the alpha channel in the call interface, replacing the transparency with black or white. It is better to use high-quality JPG.
