Full screen photo when calling in Redmi: how to set it up and why it doesn’t always work

Do you want to In an incoming call, your contact photo was displayed in full screen, rather than a small icon? This feature visually improves the experience and helps identify the caller faster. However, in the standard settings Xiaomi Redmi Was the contact's photo displayed in full screen, and not a small icon? This feature visually improves the experience and helps identify the caller faster. However, in standard settings MIUI there is no such option - it must be activated through hidden parameters or third-party applications.

In this article we will analyze all the working methods: from changing system settings to using alternative dialers. You will learn why the function may not work on some models Redmi (for example, Note 10 Pro or Redmi 12), and how to bypass the limitations. We will also analyze which image formats are best suited for full-screen display to avoid stretching or cropping.

Important: the procedure may vary depending on the version MIUI (12, 13 or 14) and smartphone model. If your Redmi works on a “pure” Android One (for example, Redmi A1), the instructions will be different - read about this in the corresponding section.

Why doesn’t Redmi have the “full screen photo” function by default?

The manufacturer Xiaomi deliberately limits the ability to display contact photos on the full screen during a call. This is due to several factors:

• 📱 Interface optimization: MIUI is designed to display information compactly so as not to distract the user from managing the call (answer/reject buttons).
• 🔋 Resource saving: rendering a large image requires more RAM, which can slow down work on budget models (for example, Redmi 9A).
• 🎨 Design solutions: MIUI 13/14 uses a translucent background with blur (AOD effect), which visually conflicts with full-screen photos.

However, the function is technically feasible - it can be enabled through Developer settings or third-party applications. Below we will look at both options.

⚠️ Attention: Changing system parameters through Developer Settings may lead to dialer malfunctions. Before experiments, create a backup copy of contacts in Google Account or through Mi Cloud.

Method 1: Enable full-screen photo through Developer Settings

This method works on most devices Redmi s MIUI 12–14, but requires prior activation of developer mode. Here are step-by-step guide:

1. Activate Developer mode:

   Go in Settings → About phone → MIUI version and tap on this item 7 times in a row. A notification “You have become a developer” will appear.

2. Find the hidden setting:

   Return to the main menu Settings, open the section Advanced → Developer Settings (or use the settings search).

3. Change the display option:

   Scroll down to block Dialer and find the option Fullscreen incoming call photo (or similar in Russian: "Photo full screen"). Switch the toggle switch to position On.

If there is no such option, then your version MIUI does not support it. In this case, go to Method 2 using third-party applications.

⚠️ Attention: On some firmware, after turning on full-screen mode, the animation of an incoming call may disappear. To get it back, reboot the device or reset the dialer settings in Settings → Applications → Dialer → Storage → Clear data.

Method 2: Using third-party dialers with Fullscreen support

If the system settings do not allow you to enable full-screen photos, the best option is to install an alternative dialer. We tested 5 popular applications and chose the top 3 with the best support Redmi:

• 📞 Truecaller:

  Allows you to install any photos on the full screen, but requires registration. Supports animations and themes. Minus: collects call data.

• 🔄 ExDialer:

  Lightweight open source dialer There is an option Fullscreen contact photo in the display settings. Plus: no advertising and tracking.

• 🎨 Contacts+:

  Designer templates for call screens, including full-screen photos. Minus: paid themes (from 199 ₽).

How install and configure:

1. Download the application from Google Play (for example, Truecaller).
2. Set it as the default dialer in Settings → Applications → Dialer → Default.
3. In the application settings, find the section Incoming calls → Screen style and select Fullscreen photo.
4. Assign high-resolution photos to your contacts (recommended: 1080×1920 px).

If after installation the dialer does not display the photo in full screen, check:

• 🔍 Application permissions (access to contacts and storage).
• 📵 No conflicts with the system dialer (disable it in Settings → Applications).
• 🔄 Application updates (in the Play Market).

How to properly prepare a photo for full-screen display

Even if you have enabled the function, a low-quality or inappropriate image will spoil the result. Follow these recommendations:

• 📏 Resolution: minimum 720×1280 px (for Redmi with screen resolution FHD+ — 1080×2400 px).
• 🎨 Format: JPEG or PNG (without transparency). WebP may not be supported.
• 🖼️ Composition: the face should occupy the central part (it will not be lost when trimming the edges).
• 🌈 Contrast: avoid dark photos - on AMOLED screens (Redmi K60) they will be difficult to see.

For cropping and optimization, use:

• Snapseed (accurate cropping and color correction).
• Lightroom Mobile (to improve contrast).
• Remove.bg (if you need to remove the background).

What to do if the photo is displayed blurry?

Blurry occurs due to automatic scaling by the system. fix:

1. Open the photo in any editor (for example, Google Photos).

2. Crop it to the exact resolution of your screen Redmi (you can find out in Settings → About phone → Screen resolution).

3. Save in format PNG with 100% quality.

4. Assign a new image to the contact via the system dialer or Google Contacts.

On devices with MIUI 14 and dynamic screen resolution (for example, Redmi Note 12 Pro+), the photo can automatically adjust to the current resolution. To disable this function, go to Settings → Display → Screen resolution and fix the value (for example, FHD+).

Problems and solutions: why the photo is not displayed in full screen

If after all the manipulations the photo is still shown in a small circle, check these points:

Problem	Possible reason	Solution
Photo is cropped at the edges	Wrong aspect ratio	Crop image to 9:16
Photo is not displayed at all	Conflict with MIUI theme	Reset theme to standard in Themes → My themes
Photo is blurry	Low source resolution	Replace with an image ≥1080px in height
Function not available in settings	Restriction of regional firmware	Install global version MIUI via Fastboot

Pay special attention regional firmware. On some Redmi for the Chinese market (CN ROM), the full-screen photo function is blocked. To get around this, you can:

1. Install global firmware (Global ROM) via Mi Flash Tool.
2. Use ADB command for forced activation:

   adb shell settings put global incoming_call_photo_fullscreen 1

⚠️ Attention: Flashing the device will void the warranty and may lead to data loss. Before the procedure, check the compatibility of the firmware with your model Redmi on the forum XDA Developers.

Alternative method: creating live wallpaper for calls

If none of the methods worked, you can take a workaround - use live wallpapers with the contact display function. Applications like Video Live Wallpaper or Kappboom allow:

• 🎥 Install video or animation on the call screen.
• 🖼️ Embed contact photos in a dynamic background.
• 🎶 Add individual melodies for each subscriber.

Setting instructions:

1. Install Kappboom from Google Play.
2. In the application settings, select Call Screen → Custom Background.
3. Upload a contact photo (recommended size: 1440×2560 px).
4. Adjust the position of the elements (reply/reject buttons) so that they do not overlap the face in the photo.
5. Activate live wallpaper in system settings (Settings → Wallpaper → Live wallpaper).

The advantage of this method is flexibility: you can create a unique style for each contact. For example, use a business background for colleagues, and bright animations for friends.

Specifics for Redmi on Android One (for example, Redmi A1, A2)

Devices Redmi based on Android One (for example, Redmi A1 or Redmi Go) do not have proprietary shell MIUI, so the full-screen photo settings are different. The standard mechanism works here. Android:

1. Open the application Google Contacts.
2. Select a contact and press Edit (pencil icon).
3. Tap on the current contact photo and select Edit photo → Gallery.
4. Crop the image so that the face occupies the central part (the system automatically scales it to fit the call screen).

On Android One the photo is displayed almost on the entire screen by default, but with a translucent bottom panel (answer buttons). To remove it:

• Install Google Phone (official dialer from Google) from the Play Market.
• In in the application settings, enable Full screen mode (Settings → Display options → Full-screen caller ID).

If after these steps the photo is still displayed incorrectly, check:

• 🔄 System updates (Settings → System → Software update).
• 📵 Conflicts with other callers (disable them in Settings → Applications).

FAQ: Frequently asked questions about full-screen photos when calling

Is it possible to take a full-screen photo without third-party applications?

Yes, but only on devices with MIUI 13/14 via Developer settings (see Method 1). On Android One or older versions of MIUI, this method does not work - you will need an alternative dialer.

Why did the photo stop being displayed in full screen after updating MIUI?

The update could reset the developer settings or change the display logic Try:

1. Restore the setting. in Developer settings → Dialer.
2. Clear dialer cache in Settings → Applications → Dialer → Storage.
3. Install global firmware, if you have a regional version (for example, CN ROM).

How to make the photo display in full screen only for individual contacts?

Standard MIUI tools do not support selective display. Solution:

• Use Truecaller or Contacts+ —in them you can assign individual screen styles for each contact.
• Create live wallpapers via Kappboom with different backgrounds for different groups of contacts.

Will a full-screen photo work during video calls (WhatsApp, Telegram)?

No, this function only applies to standard voice calls. For video calls in messengers, the display of photos depends on the settings of the application itself (for example, in WhatsApp you can enable Show contact photo in Settings → Notifications).

Is it possible to animate a photo on the call screen?

Yes, but not through standard means. Options:

• Use live wallpaper (for example, Video Live Wallpaper) with animation support.
• Install a dialer Zedgewhere there are animated themes for call screens.
• Create GIFa contact image and assign it via Google Contacts (does not work on all devices).

Please note: animation may increase battery drain during a call.
