Personalizing a phone’s call list is not just a matter of aesthetics, it’s an important element of functionality. When the screen lights up during an incoming call, instant visual recognition of the number allows you to make the right decision whether to pick up the phone or ignore the call. On a Xiaomi 9T device running a MIUI shell, this process is intuitive, but has a number of features that you should consider for proper operation.
Gadget owners often experience a situation where they see a standard grey icon with a letter of name instead of a friend or colleague’s face, this is due to the absence of a tied image in the phone’s local database or a synchronization conflict with cloud services. In this article, we will discuss in detail all the ways to solve this problem, from basic methods to working with system constraints.
In addition, we will touch on the technical nuances associated with file formats and resolutions that are optimal for the screen of your Xiaomi 9T. Understanding these details will help avoid blurry pictures or improper framing, providing a pleasant visual experience with every call.
Basic method of installing an avatar through a phone book
The simplest and most obvious method available to every user is to use the standard Contacts or Phone app, which does not require an internet connection and works with images already stored in your Xiaomi 9T memory.
To start, open the app, which usually has a green icon with a person's silhouette or phone handset. Find the alphabetical subscriber in the list of the right caller or use the search bar at the top of the screen. Once you open the contact card, you will see a round area for the photo, which by default may be empty or contain initials.
Click on the camera icon or the pencil for editing. The system will suggest you choose the source of the image: take a picture right now or choose from the gallery. Choosing from the gallery is the most popular option, because you can choose an already edited and high-quality photo.
Once you select the file, you'll have a built-in editor that allows you to frame the image, and a round frame will show you which part of the photo you'll see when you call in, and make sure that the face is in the center of the highlight area so that you don't cut off important details when you call.
- 📸 Use high-quality high-resolution source codes to make Xiaomi screen 9T The picture didn't look grainy.
- ✂️ Center your face in a round crop area, as the image angles will be automatically removed by the system.
- 💾 Save the changes by pressing the OK button or the checkmark in the corner of the screen, otherwise the new avatar will not apply.
And it's important to note that this is a method that only links the photo to a local contact, and if you change your phone or reset the settings to the factory without a backup, all the images you've installed by hand will be lost, so it's best to combine this with cloud synchronization.
⚠️ Warning: If it doesn't show up immediately after saving the photo, try restarting the device. MIUI Sometimes you need to update to display new graphics.
⚠️ Warning: Avoid using photos with transparent background in format PNG, Some versions of the shell may not properly handle the alpha channel, replacing the transparency with black or white.
Working with Google Contacts for Synchronization
A more reliable and modern way is to use the Google Contacts cloud service, which ensures that your data, including photos, is saved even if your device is lost or broken, and that changes made from one device will instantly affect all devices where you log in to the same account.
To take advantage of this, make sure your Xiaomi 9T has sync enabled. Go to system settings, find the Accounts and Sync section, and select your Google account. Make sure the switch opposite the Contacts item is activated.
The process of adding photos through this service is similar to the local one, but it has an important difference: when you select an image and save it, it is uploaded to Google servers, which means that the amount of storage in the cloud increases, although the photos usually take up a little space.
If you add a photo through the Google Contacts web interface from your computer, it will automatically appear on your phone when you have the Internet, which is very convenient for mass editing the call list when you have a mouse and a large monitor at hand to select the best shots.
☑️ Checking Google Syncs
However, there is a nuance related to display priorities: sometimes the phone may show photos from a social network instead of what you uploaded to Google. To avoid confusion, it is recommended that you select the source “Phone Only” or “Google” in the contact display settings, eliminating third-party apps.
Automatic download from social networks and instant messengers
Modern smartphones, including the Xiaomi 9T, can automatically pull up avatars from popular messengers such as WhatsApp, Viber or Telegram. This happens if the phone number in the notebook matches the number registered in the application, which saves time, but can lead to conflict versions of the photo.
Often users notice that a hand-mounted photo is replaced after a while with a picture from the messenger, which is caused by the synchronization settings of the messenger application itself, for example, WhatsApp has its own contact database, which can overlap the system.
To manage this process, you need to go to the settings of each messenger separately. In the section “Privacy” or “Chats”, you can often find a paragraph responsible for media visibility or synchronization of avatars, disabling this feature will return control over the images to the user.
If you want to use a photo from a messenger, but it's not in the system ledger, you can use the export function. Some apps allow you to send a contact with a photo in.vcf format, which when opened will prompt you to save the data to the phone book.
- 🔄 Regularly check if the avatars in messengers have been updated, if you need an actual photo of the interlocutor.
- 🔒 Keep Privacy in mind: By syncing contacts, you give instant messengers access to your phone book.
- ⚙️ Set the priority of photo sources in the Contact Display menu to choose which image to show first.
⚠️ Note: When you remove a messenger (such as WhatsApp) from your phone, the avatars tied through it may disappear from the phone book if they were not saved locally or in Google.

Technical requirements for images and formats
To ensure the best display quality on the screen Xiaomi 9T with its AMOLED-matrix, it is important to consider the technical parameters of the downloaded files. Although the system automatically scales any images, using optimal formats avoids compression artifacts.
It is recommended to use images in JPEG or PNG format. JPEG format is preferred for people's photos due to effective compression without visible quality loss. PNG is worth using if you want an image with a transparent background or clear graphics, although for portraits it is less efficient in file size.
Picture resolution also plays a role. The screen of the smartphone has a high resolution, so miniature images (less than 200x200 pixels) will look blurry. The optimal size is 500x500 pixels and above. The system itself will cut the excess to a circle, but the source must be of quality.
The file size doesn't have to be too big. Although modern phones have a lot of RAM, downloading a photo of a few megabytes in size for a single contact is not feasible, which can slow down the scroll through the contact list and consume traffic when synchronized.
| Parameter | Recommended value | Minimum value | Impact on the system |
|---|---|---|---|
| File format | JPEG / JPG | PNG | Compatibility and size |
| Permission | 500x500 px and higher | 200x200 px | Clearness of image |
| File size | 500 kb | 2 MB | Menu speed of operation |
| Relationship of parties | 1:1 (Square) | Anybody | Quality of framing |
💡
Use the built-in editing tools in the MIUI gallery before you install your photo, where you can quickly apply filters, sharpen your image and crop it in a 1:1 square, which is ideal for a round avatar.
Removal: Photos not displayed or reset
Xiaomi 9T users may experience a situation where the installed photo disappears after a reboot or is not visible to the caller.One common reason is the aggressive battery optimization characteristic of the MIUI shell. The system can clear the cache of the Contacts app by deleting temporary image files.
To fix this, you have to stop the system from closing the contact app, go to the battery settings, find the Contacts or Phone app, and set the No Limits mode, which allows the process to run in the background and store data in the cache.
Another common problem is duplicate contacts, if you have two records of the same person (e.g., one in a single file). SIM-If you're looking at a map, another one on Google, the system can only display a photo for one of them or not display it at all because of a conflict.
Find the settings menu in the Contacts app and select “Combine duplicates.” The system will analyze the list and suggest connecting the entries with the same numbers or names. Once combined, a photo associated with one of the entries should become visible to the general contact.
- 🧹 Clean up duplicates regularly to make the database faster and more accurate.
- 🔋 Check the permissions of the Contacts app in the Apps section» → «Permissions, make sure that access to memory is allowed.
- 📱 If the problem is massive, try clearing the Contacts app cache through the application settings without deleting data.
⚠️ Attention: Clearing the Contacts app data (not the cache, but the data) will delete all local numbers and photos if they are not synced to the cloud.
Set up the display of the photo when calling the full screen
Owners of Xiaomi 9T appreciate their smartphone for a quality screen, and it is a shame if during the call the photo of the contact is displayed only in a small circle. Depending on the version of MIUI and the theme of the design, the interface of the incoming call may differ.
To make a photo take up the entire screen or most of it, you often need to change the theme. A standard theme can have limitations. Go to the Topics app, look for Profile or My Pages, and try to set the theme where the full screen photo is claimed when you call.
It's also worth checking the settings of Telephony itself. Some firmware versions have a full-screen photo or call background option, and activating this item will stretch the contact image, filling up all the free display space during a conversation.
If standard tools fail to achieve the desired effect, you can use third-party applications to manage calls from the Google Play store. They completely replace the incoming call interface, offering flexible settings for displaying photos, blurring backgrounds and animations.
💡
For maximum quality display of photo contact on the full screen on Xiaomi 9T, it is best to use third-party themes from the Mi Themes store, as the standard interface can limit the size of the avatar.
