How to take a full-screen contact photo in Xiaomi Redmi 10: 5 proven ways

Owners of Xiaomi Redmi 10 often face a problem: when you call, a photo of the contact is displayed in a small circle, not on the entire screen. This not only spoils the visual perception, but also prevents you from quickly identifying the subscriber. Fortunately, MIUI has several ways to fix this, from standard settings to hidden functions.

In this article, we’ll break down all the current methods, including official phone settings, third-party apps, and even manual edits to system files (for advanced users), learn how to make a contact photo take up the entire screen when an incoming call is made, and how to avoid typical setup errors.

Importantly, not all methods are equally safe, some require unlocking the bootloader or root rights, which can lead to a loss of warranty, and we will note the risky steps with special warnings.

Why is the photo of the contact not displayed on the full screen?

The problem with scaling photos in Redmi 10 is related to the features of the MIUI shell. By default, the system uses a round cropping of avatars to make them fit into the standard call interface.

• 🔹 Design unification (all contacts look the same)
• 🔹 Resource savings (handling a round mask is easier than scaling)
• 🔹 Compatibility with themes (some themes break the display of full-screen photos)

However, the latest versions of MIUI 12.5+ have the option to change this setting, so if you have an older firmware, you’ll have to upgrade or use workarounds.

⚠️ Note: If you use third-party launchers (like Nova Launcher), your contact display settings may be reset. MIUI.

This command will open a hidden menu of contact display settings, where there may be a full-screen option.

Method 5: Manually changing the resolution of photo contact

Sometimes the problem is not the settings, but the resolution of the original photo, so if the image is too small, the system automatically crops it to a circle.

• 📏 Minimum photo resolution: 720×720 pixel.
• 🎨 Format: JPEG or PNG (transparently).
• 🔍 Aspect ratio: 1:1 (square).

How to prepare a photo:

1. Open the image in any graphics editor (such as Photoshop or PIXLR).
2. Cut it to square.
3. Increase the resolution to 1080×1080 (optimum for Redmi 10).
4. Save and assign contact.

If the photo is still displayed in the circle, try to resave the contact:

1. Export the contact to the.vcf file.
2. Remove him from the phone.
3. Import back.

💡

Proper resolution is key to success. Even if MIUI settings allow full-screen mode, low-quality images will be automatically cropped.
