Modern smartphones allow you not only to hear who is calling you, but also to see that face in full screen even before you swipe to answer. The function Call Screen or "Photo on call" has become a standard for most Android shells, from pure Pixel UI to proprietary One UI i MIUI. However, many users still do not know how to activate this option or why the installed image is not displayed.
The setup process may vary significantly depending on the version of the operating system and the model of your device. In some cases, the system requires special permissions, in others it is enough to simply select a file from the gallery. Understanding these nuances will help you avoid common mistakes when personalizing the call interface.
In this article we will look in detail at all the ways to set images: both for a specific contact from the phone book, and a global setting for all unknown numbers. We will also touch on the technical limitations of file formats and the reasons why the picture may not appear on the lock screen.
Image preparation and technical requirements
Before moving on to the menu settings, you must properly prepare the file that you plan to use. The Android system has certain restrictions on resolution and aspect ratio, ignoring which will result in the photo being cropped or displayed incorrectly. The optimal choice is a vertical image with a resolution of at least 1080×1920 pixels.
If you use older smartphone models with low-resolution screens, the requirement can be reduced to 720×1280, but for modern displays it is better to use high-quality sources. Horizontal photos, when set to fill the entire call screen, will be heavily cropped at the edges, leaving only the central part of the frame visible.
Particular attention should be paid to the file format. While most contact managers support JPEG and PNG, some skins, such as ColorOS from OPPO or Funtouch OS from Vivo, allow you to set even short videos or GIF animations as call backgrounds. For static pictures, the file weight should not exceed 5-10 MB so as not to load the RAM during an incoming call.
⚠️ Attention: Avoid using images with a transparent background (PNG format with an alpha channel) for global call settings. On different devices, transparency may appear as a black or white background, which will spoil the composition.
Use photo cropping applications to set the aspect ratio to 9:16 in advance. This ensures that the subscriber’s face does not appear outside the screen during a call.
Setting a photo for a specific contact
The most common scenario is setting a unique avatar for a loved one or an important client. This allows you to instantly identify the caller without even looking at the name. The process begins by opening the standard application Contact or Phonewhere your phone book is stored.
Find the desired subscriber in the list and open his card. At the top of the screen, where there is usually a gray blank with initials, you will see a camera or pencil icon. Clicking on this element opens a menu for selecting the image source: you can take a photo right now, select a file from the gallery, or download from cloud storage.
After selecting a file, the system will offer to crop the image. The cropping interface is usually a moving frame. Make sure that key details (face, eyes) are in the center of the selection area, since when calling, the edges may be hidden by elements of the call answering interface.
- 📸 Click on the camera icon in the contact's profile to start editing.
- ✂️ Adjust the cropping frame, shifting the focus to the central part of the portrait.
- 💾 Confirm saving by clicking the checkbox or the "Done" button in the corner of the screen.
It is worth noting that synchronizing contacts through your account Google can overwrite a locally installed photo with one stored in the cloud. If you want the picture to remain exactly the way you set it, check the synchronization settings in the section Settings → Accounts → Google.
Global background settings for all calls
If you want to replace the standard dark or blurry screensaver with your own image for all incoming calls calls, including unknown numbers, the procedure will be different. This feature is often called "Ring Theme" or "Call Style" and is located in the settings of the phone application itself, not in Contacts.
Go to the application Phone and click on the three dots in the upper right corner to open the menu. Select item Settings. In the list that opens, look for a section that may be called Call visualization, Themes or Call background. The names vary depending on the device manufacturer.
Inside this section you will see a gallery of pre-installed themes and a button to add your own image. After selecting a photo from the device memory, it will be applied to all incoming connections for which an individual avatar is not specified. This is a great way to make the smartphone interface more unique and pleasing to the eye.
Path to settings (example for Samsung):
Phone → Three dots → Settings → Background and call style → Add
Some manufacturers, for example Xiaomi in the shell HyperOS, they offer the “Video call” function, which allows you to play a short video when there is an incoming call. This option requires more processor and battery resources, so may experience delays on budget devices.
The global call theme is only applied when the caller does not have a saved individual photo in your phone book. Priority is always given to the contact's personal avatar.
Features of interfaces from different manufacturers
The Android ecosystem is fragmented, and each vendor makes its own changes to the standard code. What works on “pure” Android in smartphones Google Pixel or Motomay look completely different on devices Huawei or Samsung. Understanding these differences is critical to successful setup.
On devices Samsung with a shell One UI the feature is called "Background and Call Style". It is integrated deeply into the system and even allows you to apply filters to the selected photo. While in Xiaomi i Redmi this function is often placed in a separate “Themes” application, where you need to download design packages.
Below is a table showing the differences in the paths to settings for popular brands. Use it as a cheat sheet if you can’t find the desired item in the menu of your smartphone.
| Brand / Shell | Section name | Path to settings | Video support |
|---|---|---|---|
| Samsung (One UI) | Background and call style | Phone → Settings → Background and style | Yes (partially) |
| Xiaomi (MIUI/HyperOS) | Themes / Wallpaper for calls | App Themes → Profile → Wallpaper for calls | Yes (full) |
| Google Pixel (Stock) | Themes | Settings → Wallpaper and style → Lock screen | No (photo only) |
| Honor (MagicOS) | Style call | Phone → Four dots → Call style | Yes |
Owners of smartphones Honor i Huawei should be careful: the latest firmware versions do not have services Google functionality for installing video calls may require the installation of additional plugins from the store AppGallery. Without them, only installation of static images is available.
⚠️ Attention: Interfaces are updated with each firmware version. If you do not find the specified item, use the search by settings (magnifying glass icon at the top of the settings menu) and enter the request “call” or “background”.
Solving problems with displaying pictures
Sometimes users are faced with a situation where all the settings are made correctly, but when the incoming When calling, only a gray silhouette or operator logo is displayed. This may be caused by a conflict of access rights or the way the lock screen works.
The first thing you need to check is the permissions for the application Phone i Contact. Go to Settings → Applications, find the application you need and make sure it has access to Memory or Photo and video. Without this right, the system cannot load an image from the gallery at the time of the call.
Second frequent The reason is energy saving. Aggressive battery optimization algorithms can kill the background rendering process to save battery. Try disabling the power saving mode or adding the phone application to the exception list (do not limit it in the background).
- 🔋 Check if the Ultra-Saving mode is enabled at the time of the call.
- 🔒 Make sure that private content is allowed to be displayed on the lock screen.
- 🗑️ Clear the cache of the Phone application through the app settings menu.
Why is the photo not visible on the locked screen?
On some devices (especially Samsung and Xiaomi), privacy settings prohibit showing detailed information about the caller if the phone is locked. Go to Settings → Lock screen and allow notification and call details to be shown.
Also, the problem may lie in the image file itself. If the photo weighs too much (for example, a raw RAW file or 4K image) or has a non-standard color profile, the system may not have time to decode it a split second before picking up the phone.
Advanced settings and third-party applications
If the standard functionality of your smartphone does not allow you to set the desired picture or video, third-party solutions from store Google Play. There are many dialer applications and theme managers that intercept an incoming call and display their interface on top of the system one. Popular applications, such as specialized ones, offer huge databases of ready-made wallpapers and video effects. They often have more flexible animation settings and allow you to link different topics to different groups of contacts.
Popular apps such as Truecaller or specialized Call Screen Themes, offer a huge database of ready-made wallpapers and video effects. They often have more flexible animation settings and allow you to link different topics to different contact groups.
However, using such apps has its drawbacks. They consume more RAM and may cause a delay in displaying the caller's number. In addition, to operate, they require constant access to the call log and contacts, which raises questions among some users in terms of privacy.
Example command to reset the dialer settings (via ADB):
adb shell pm clear com.android.dialer
For experienced users who own the rights Root, it is possible to completely replace the system resources responsible for the screen call. This allows you to change even the icons of the answer buttons and fonts, but requires deep knowledge of the system and carries the risk of turning the phone into a “brick” if there is an error.
☑️ Diagnosing a problem with a photo
⚠️ Attention: When installing third-party dialers, remember that they become the default application for calls. To return to standard dialing, you need to manually change the default application in the system settings.
Frequently asked questions (FAQ)
Is it possible to install GIF animation instead of a static photo?
Yes, it is possible, but depends on the phone model. Xiaomi, Realme and some Samsung smartphones support setting GIFs or short videos as call backgrounds. On “pure” Android (Pixel, Motorola), this function is usually not available without third-party applications.
Why did the call picture reset after updating Android?
Major system updates often reset user theme and wallpaper settings to factory settings. This is standard behavior to ensure the stability of the new software version. You will need to re-select the image in the call theme settings.
Does the caller see what picture I have installed on his number?
No, the installed photo is visible only to you on your screen. The subscriber on the other end of the line sees the standard interface of his phone. The exception is video calls through instant messengers or operator video call services (ViLTE), where video transmission is two-way.
How to remove the call picture and return the standard background?
Go to the Phone application settings → Call background (or Theme). From the theme gallery, select Default, Standard, or System. This will return the original design provided by the manufacturer.
Does the installed video on a call affect battery consumption?
Yes, using video wallpapers or heavy animated GIFs during a call increases battery consumption, since the screen operates at high brightness and the processor decodes the video stream. To save energy, it is better to use static images.
