How to take a full screen photo of a caller on Xiaomi Redmi 9: 5 proven ways

Owners of Xiaomi Redmi 9 often find that the contact photo when an incoming call is displayed too finely - in a small circle in the center of the screen. This is inconvenient, especially when you need to quickly identify the caller without looking at the small image. Fortunately, MIUI firmware has hidden settings that allow you to stretch the photo to the full screen, and for some versions even available alternative solutions through third-party applications.

Many users mistakenly think that this requires root access or complex manipulation of system files. In fact, 90% of tasks are solved through standard menus - you just need to know where to look. In this article, we will discuss all the working methods, from the official settings of MIUI 12/13 to workarounds for older versions of firmware, and you will learn why sometimes the photo does not appear at all and how to fix it.

If you want to not only zoom in but also customize the incoming call screen (like changing the background or adding animations), there’s a bonus section at the end of the article with instructions for installing themes from the Mi Theme Store.

1. Standard setting in MIUI: zoom in on the photo via "Phone Settings"

The easiest way is to use the firmware options built in. Depending on the version of MIUI, the path to settings may vary slightly, but the general logic is maintained. Importantly, this method only works for contacts who already have a photo in their phone book.

Here is a step-by-step guide for Xiaomi Redmi 9 with MIUI 12.5+:

• 📱 Open the Phone app (the tube icon on the home screen).
• 🔧 Click on the three dots in the upper right corner and select Settings.
• 🖼️ Go to the Incoming Calls section → Call screen style.
• 🔍 Select Full Screen Mode or Enlarged Photo (name may vary).
• 🔄 Reboot your phone to make the changes take effect.

If you don't have Full Screen Mode on your menu, then your version of MIUI doesn't directly support this feature, so move on to the following ways.

Make sure your contact has a photo in the phone book.|Update the Phone app in Google Play|Check the version. MIUI in the "About the phone" settings"|Restart the device before changes-->

Important! On some firmware, the option is hidden behind an extra menu. Try holding your finger on the empty spot of the call screen during a test call - sometimes this opens up hidden style settings.

2. Alternative method: using themes from the Mi Theme Store

If standard settings don't work, you can set up a special theme that automatically stretches the caller's photo. The Mi Theme Store has dozens of themes with customized call screens, including full-screen options.

How to do this:

• 🎨 Open the Themes app (icon with brush).
• 🔍 Enter Full Screen Call or Big Photo Caller.
• 📲 Choose your favorite theme and click Apply.
• 🔄 Wait for the installation to be completed and restart the phone.

Note that some themes can change not only the size of the photo, but also fonts, color scheme and animations. If you do not like additional changes after applying the theme, return the standard theme to the same menu.

Standard. MIUI|The big photo theme|Minimalist (name and buttons only)|Animated (with effects)|Your custom.-->

⚠️ Note: When using third-party themes, there may be bugs with Chinese characters instead of Russian text, due to incorrect localization of some topics. Solution: read reviews from other users before installing them.

3. Manual editing of photo contact for better display

Sometimes the problem isn't with the phone settings, but with the contact image itself, and if the photo is too small or has the wrong resolution, MIUI can automatically compress it to a minimal size.

• 📏 Permission: Optimal size — 1080×1920 pixels (partial ratio) 9:16).
• 🖼️ Format: Use PNG or JPEG High quality (minimum 80%).
• 👤 Image: The face must occupy at least 60% of the image area.
• 🎨 Background: Better monochromatic or with minimal pattern, so as not to distract from the face.

To change the contact photo:

1. Open Contacts and select the profile you want.
2. Click on the camera icon next to the current photo.
3. Select the Gallery and upload the edited image.
4. Cut the photo on the proposed grid (try to fill the maximum area).

The critical thing is, if the photo still shows up fine after you replace it, check if the contact with your Google account is synced, so MIUI can upload the compressed version of the image from the cloud, so you can turn off sync for that contact, or upload it directly to your local phone book.

4. Third-party applications for customizing the call screen

If the built-in methods didn't work, you can use third-party apps that offer flexible settings, including full-screen photo displays, animations, and even video calls.-3 tested solutions:

Before installing any of these applications:

1. Make a backup of your contacts (via Settings → Google → Backup).
2. Check the permissions the program requests (don’t give SMS access unless required for basic features).
3. Test the app on a test contact before applying to all calls.

💡

If after installing a third-party application, the call screen began to lag, clear the cache of the Phone application in the Xiaomi Redmi 9 settings. To do this, go to Settings → Applications → Application Management → Phone → Storage → Clear the cache.

5. Solving the problem: why the photo is not displayed or remains small

Even after all the settings, the caller's photo may remain small or not at all, and here are the most common reasons and solutions:

• 🔄 Phone app cache: Clean it as described in the previous section.
• 📱 Update MIUI: Check for updates in Settings → The phone. → System update: Newer versions often fix display bugs.
• 🔗 Google Sync: Turn it off for troubled contacts (see Section 3).
• 🛠️ Resetting the settings of the Phone application: Go to Settings → Annexes → Phone. → Additionally. → Reset the settings.
• 📵 Conflict with other applications: If you have a second dialer installed (for example, from a bank), it can intercept the call screen.

⚠️ Note: Some Xiaomi Redmi 9 firmware (especially Chinese versions) have the full-screen photo option blocked by the manufacturer, in which case only flashing to the global version will help. MIUI or use of third-party applications.

6. Additional chips: animation, videophone and custom sounds

If you've already set up a full-screen photo, why not go further? There are plenty of options for customizing the call screen in MIUI and third-party apps:

• 🎬 Videophone: Truecaller and Call Screen Pro can use a short video instead of a static photo, suitable for loved ones or corporate contacts.
• 🔊 Individual Melodies: Assign a unique ringtone for important contacts through Contacts → Edit → The melody of the call.
• 🌈 Animations: The Mi Theme Store has themes with dynamic effects (for example, a pulsating circle around a photo or a smooth appearance of buttons).
• 🔒 Hiding the number: For privacy, you can hide the caller’s number, leaving only a photo and name (the setting is in Call Screen Pro).

For the most advanced users, there is an option to create your own theme through MIUI Theme Editor (requires PC and knowledge of basics of working with the computer) APK-However, this is a complex process that we recommend only if you have tried all other methods.

💡

Remember: over-customization can reduce the performance of the phone. If after applying themes or applications Xiaomi Redmi 9 began to slow down, return the standard settings or perform optimization through Settings → Special features → System optimization.
