Personalizing a mobile device is not just a tribute to aesthetics, but also a way to instantly identify the caller. Xiaomi Redmi 9 owners often face the need to assign specific images to subscribers from the phone book to immediately understand who is bothering. Standard MIUI settings provide a flexible enough toolkit to solve this problem, but the algorithm of actions may differ from the usual for many users of pure Android.
The process of installing an avatar may seem trivial, but the MIUI ecosystem has its own nuances regarding cloud sync and application access rights. The wrong approach can lead to the photo being saved locally, but not displayed during an incoming call or in messengers. Understanding the storage architecture in Redmi 9 will avoid such situations and ensure the stable operation of the visual identifier.
In this article, we will discuss in detail all available methods of fixing an image to a phone number. We will consider both the standard system tools and the capabilities of third-party applications that can be useful in certain use cases.
Image Preparation and Format Requirements
Before you start the technical part of the process, you need to make sure that the source file meets the technical requirements of the system. Android operating system, based on which the shell MIUI, is omnivorous enough, but for the correct display in round or square widgets interface better use images of a certain quality. The optimal choice will be files in JPG or PNG format with a resolution of at least 500x500 pixels.
If you plan to use a high-resolution photo, such as taken on the main camera of Redmi 9 itself, the system will automatically compress when installed. However, excessively large files can slow the opening of contact in the phone book. It is recommended to crop the image in advance, leaving the main object in the center, as when displayed on the call screen, the edges can be cut off.
💡
Use square images with a 1:1 aspect ratio – this ensures that the face or important object will not be cut when the avatar is rounded in the MIUI interface.
The IPS screens in this model are great at conveying colors, but too dark or contrasting photos can be difficult to read in bright sunlight. Contrast plays a key role if you often take calls outside.
- 📸 Choose photos where the face occupies the central part of the frame.
- 🎨 Avoid colorful backgrounds that distract from the main object.
- 📐 The optimal file size for fast download is up to 2 MB.
- 💾 Formats PNG and JPG Supported natively without conversion.
Installation of photos through the standard Contacts app
The most direct and reliable way to assign an image to a subscriber is to use the built-in Contacts app, which ensures that the data is stored in the correct structure of the phone book database. To begin, open the app, which usually has a green icon with a human silhouette, and find the subscriber in the list.
When you open your contact card, look at the top of the screen, and you'll usually have a round area with initials or a standard gray plug, and if you click on that area or the edit button (often looks like a pencil), you'll open a data change menu, and if you open the menu, you'll want to select the option to add or replace a photo.
☑️ Algorithm of installation of the avatar
The system will offer multiple sources to get the image. You can choose an existing photo in the gallery, take a picture right now, or choose from the avatars offered by the system. Once you select the file, the framing editor will open. Here, it is important to set the boundaries correctly so that the image does not lose quality when zooming, the final step is to click on the "Done" or "Save" button.
It's important to note that if a contact is linked to a Google or Xiaomi Cloud account, the photo can sync to other devices, which is convenient, but requires a stable Internet connection. SIM-cards, add to it a photo with regular means is often impossible due to the limitations of the format of data storage on the SIM.
⚠️ Note: When you try to add a photo to the contact saved on the SIM-The system may give an error or not show the download button, in which case you must first copy the contact to the memory of the phone or Google account.
Using the gallery for quick installation
There is an alternative, and often faster, way to install an avatar that users who love working with visual content will appreciate. The method is to go from the opposite: first select the right image in the gallery, then assign it to the contact. This is especially handy when you have a series of shots and you want to choose the best one right away.
Open the Gallery app and find the photo you want. Click on it to view it in full screen. In the bottom menu or in the Three Dots menu, you need to find "Appoint" or "Install as." In the list of use cases that opens, you should select "Contact".
Then the system will offer a list of subscribers from your phone book, and you can use a name search to quickly find the person you want, and once you pick the contact, you end up with framing and saving, and the good thing about this is that you can see what the photo will look like in full size before you tie it to the number.
Why can't the photo appear right away?
When using this method, it is important to remember access rights. The Gallery app must have permission to change the contact data. Usually the system requests this automatically on the first attempt, but if access was previously denied, the function will not work. You can check the permissions in the Settings section → Applications → Gallery → Rights.
Synchronize contacts and avatars through Google
For Android smartphone owners, including Xiaomi Redmi 9, the Google ecosystem offers a powerful sync tool: Keeping contacts together with photos in your Google account ensures that when you lose your phone, flash or buy a new device, the entire phonebook will recover from its original form along with the images.
To make sure your photos are saved to the cloud, check your sync settings. Go to Settings → Accounts and Sync → Google. Make sure the switch opposite Contacts is active, in which case any change, including the installation of a new photo, will automatically go to Google servers.
The advantage of this approach is cross-platform. If you add a photo to a contact via Google Contacts web interest on your computer, it will automatically appear on your Redmi 9 after synchronization, which eliminates the need to forward files and waste time on the mobile interface.
| Parameter | Phone memory | Google account | SIM-map |
|---|---|---|---|
| Photo storage | Supported | Supported | Not supported |
| Synchronization | No (locally) | Automatic. | No. |
| Photo quality | High. | Optimized | N/D |
| Risk of loss | High (on discharge) | Minimum | Medium. |
💡
Synchronization with Google is the only way to guarantee the safety of contact photos when the phone’s settings are completely reset to factory state.
Setting up the display of a photo during a call
Sometimes users are faced with a situation where a photo is in contact, but during the incoming call, a standard stub is displayed, this may be due to the settings of the theme or the specific parameters of the Phone application. In MIUI, both the system application and the installed theme can be responsible for visualizing calls.
First, check if the theme is blocking the display of images. Some third-party themes downloaded from MIUI Themes store have their own call screen design that ignores the system contact avatars. Try switching to a standard theme to see if it's the cause.
Also worth checking is the settings of the Phone app. Open the app, click three dots in the corner, and select Settings. Find the section associated with the call screen or caller identification. Make sure there's no restriction on showing only text information. Some versions of MIUI have a Smart Call Screen feature that can overlaid standard photos with its widgets.
- 🎨 Check if you are using a theme with a custom call screen.
- 📞 Make sure the number is in an international format (e.g, +7...).
- 🔄 Clear the cache of the phone application through the settings.
- 👁️ Check if the "Do Not Disturb" mode with the concealment of details is enabled.
Another common problem is duplicate contacts, and if you have two contacts in your phone's memory with the same name but different numbers, or the same number is stored twice (e.g., one on Google, the other on your phone), the system may be confused about which avatar to show, and this helps to combine contacts.
⚠️ Note: If the phone number is written without a country code (e.g. 8900... instead of a country code) +7900..), and the caller is identified by the operator with the code, the system may not link the number to the contact and show the photo.
Solution: Photo not saved or visible
Despite the ease of operation, users of Xiaomi Redmi 9 can experience technical failures. One of the common reasons is overflow of the cache of the system or a particular application. Over time, the contact database can grow, and new records cease to be correctly indexed.
To solve the problem, try to clear the Contacts app data (not to be confused with deleting the numbers themselves, the data is usually not lost when cleaning the cache if there is synchronization, but it is better to make a backup). Go to Settings → Apps → All apps → Contacts → Storage → Clean. After that, restart the device.
The problem can also be in the image file format. Although Android supports many formats, some specific codecs or corrupted metadata files (EXIFs) can cause processing errors. Convert the image to a standard JPG through any online service or application and try installing it again.
If nothing works, check the amount of free memory. With a critically low amount of free space (less than 100 MB), the system can block the writing of new data to the contact database, including graphics files. Freeing up space often solves the problem instantly.
