How to increase the photo of a contact to the full screen when calling Xiaomi Redmi 8T: 4 working ways

Why a contact photo doesn’t show up on the full screen and how to fix it

Owners of Xiaomi Redmi 8T often face a problem: when an incoming call, a subscriber’s photo is shown in a small circle, rather than stretching over the entire display. This is standard MIUI behavior, but it can be changed through both standard settings and hidden features. In this article, we will discuss all the current methods for MIUI 11-14 firmware, including bypassing the restrictions for contacts without a photo.

The main reasons why the image does not occupy the entire screen:

• 🔹 Full screen mode is disabled in the phone settings (by default) MIUI compact).
• 🔹 Incorrect resolution of photo contact (MIUI Automatically crops images with an aspect ratio other than 1:1).
• 🔹 System restrictions for contacts without an attached image (default avatar is shown).
• 🔹 Conflict of design topics - some custom themes MIUI block out full-screen mode.

Before settings, make sure the contact has a high-resolution photo upload (minimum 500×500 px). If the image is missing, MIUI will substitute a standard icon that cannot be stretched across the entire screen.

Method 1: Enabling full screen mode in phone settings

The easiest method is to activate the corresponding option in the Settings menu. → Screen. This works on all versions. MIUI, It may not be available on some custom firmware.

1. Open the Settings app (the gear icon on the home screen).
2. Go to the Screen section.
3. Find Full Screen Call Mode (or Call Screen Style in MIUI 14).
4. Activate the switch next to the Full Screen Photo option.
5. Restart the device to apply the changes.

If Full Screen Call Mode is not on the menu, then your version of MIUI does not support it. In this case, go to Method 2.

Make sure your contact has a high quality photo

Check the version of MIUI in the settings (section "About the phone")

Disable energy saving mode (can block changes)

Reboot your phone before setting up

⚠️ Note: Some of the Redmi firmware 8T When you turn on full screen, the call response button may disappear. To return it, go to Settings. → Special facilities → Answer the call and activate the Answer button option on the lock screen.

Method 2: Change the style of the call screen through MIUI themes

If the standard settings don't work, try changing the system theme. Some MIUI themes by default support full-screen photo display when calling, even if this option is hidden in the menu.

Instructions:

1. Open the Themes app (brush icon on the home screen).
2. In the My Topics section, click Online Topics.
3. In the search bar, enter a request: full screen call or full screen call.
4. Select any theme marked Full Screen Caller ID (e.g. Miui Pro or Dark Mode Full Screen).
5. Click Apply and confirm installation.

After changing the topic, check the incoming call — the contact photo should stretch across the screen. If there is no change, return the standard theme and move on to the next method.

💡

If the app icons are missing after changing the theme, return the standard theme and clear the cache to Settings → Applications → Application Management → Themes → Storage → Clear the cache.

Method 3: Editing a contact for forced display of a photo

MIUI may not show the full screen photo if the contact image does not meet the system requirements. To fix this, edit the photo in the phone book:

1. Open the Contacts app.
2. Find the right contact and click on it.
3. Slip the pencil icon (Edit).
4. Click on the current contact photo and select Change the photo.
5. Select a new image from the gallery or take a picture with the camera.
6. Cut the photo so that the face occupies 80-90% of the frame (MIUI automatically centers the image when you call).
7. Save the changes and make a test call.

A critical nuance for the Redmi 8T: the system ignores photos with a resolution below 300×300 px or with an aspect ratio other than square (1:1). If your image is elongated (for example, 1920×1080), MIUI will cut it to a circle, and the whole screen it will not stretch.

⚠️ Note: If you sync contacts with your Google Account, photo changes may not apply due to caching. To reset the cache, go to Settings → Accounts. → Google → Synchronize contacts and temporarily turn off sync for 5 minutes.

Method 4: Using third-party apps to customize calls

If the standard methods didn't work, install an alternative call app.The best options for Redmi 8T are:

• 📞 Truecaller – supports full-screen photos and spam call identification.
• 📞 Drupe – allows you to customize the style of the call screen, including stretching photos.
• 📞 Contacts+ — has a built-in photo editor contacts with preview.

Instructions for Truecaller:

1. Install an app from the Play Market.
2. Open the Truecaller Settings → Call screen.
3. Select Full Screen Mode.
4. Activate the option to show a photo of the contact.
5. In the Style section, select Modern Full Screen.
6. Make Truecaller the default call app in Android settings.

The advantage of this method is flexible setting (you can even add animation photos), the disadvantage: some features of Truecaller require a premium subscription.

💡

The side of the call app may conflict with MIUI Dialer. If incoming calls are lost after installation, return the standard app to Settings → Applications → Default → Phone.

The solution to the problem: why the photo is not stretched to the full screen

If none of these methods worked, check out these points:

If the problem persists, reset the phone app settings:

1. Go to Settings → Applications → Application Management.
2. Find the phone (or Dialer) and open its settings.
3. Press Warehouse. → Clear the data.

Additional tips for customizing the call screen

In addition to stretching the photo, you can configure other call screen settings on Redmi 8T:

• 🎨 Color scheme: In the themes MIUI You can change the color of the background, font and buttons.
• 🔔 Sound and vibration: In Settings → Sounds and vibrations → The sound of the call set up unique tunes for different contacts.
• 📱 Gestures: Include the response/deflection of the swipe call in Settings → Special facilities → Answer to the call.

For advanced users, if you're willing to take the risk, you can edit MIUI system files through ADB or Magisk modules. For example, the Full Screen Caller Photo module for Magisk compulsorily includes full-screen mode for all contacts. However, this requires an unlocked bootloader and can cause system failures.
