How to take a photo of a full-screen caller in Xiaomi: full instructions with nuances

Are you tired of the small contact avatars that are barely visible when you make an incoming call on your Xiaomi? Want a subscriber photo to occupy the entire screen, like on banner ads or on premium smartphones? This feature does exist — but it needs to be set up correctly. Depending on the MIUI version and phone model (be it Redmi Note 12, POCO X5 or Xiaomi flagship 14), the activation methods can vary.

In this article, you will find 3 working methods for increasing a caller’s photo, from standard settings to hidden MIUI features that are not even mentioned in the official documentation. We will also analyze common errors (for example, why the photo is cropped or not displayed at all) and give recommendations for optimizing images for perfect display. If you are a Xiaomi user with Android 11-14, this guide is for you.

Why the default photo is small: technical reasons

Smartphone manufacturers, including Xiaomi, often limit the size of avatars when making calls due to two key factors:

• 📱 Resource savings: Large image rendering requires more RAM and CPU power, which can affect interface smoothness on budget models (e.g. Redmi). 10A or POCO M5).
• 🔄 Compatibility with MIUI: shell MIUI uses a unified design for all devices, and scaling the photo under different screen resolutions (from the 720p before 4K) It requires additional algorithms.
• 🛡️ Security: Large images can overlap important interface elements (response/deflection buttons), which increases the risk of accidental clicks.

However, in the latest versions MIUI 13-14 allows you to flexibly configure your contacts, including full-screen photo mode, the problem is that this option is often hidden in deep settings or requires activation through a remote setting. ADB-Next, we'll show you how to find it and turn it on.
