How to increase contact photos when incoming call on Xiaomi: the complete guide

Modern Xiaomi smartphones, which use the MIUI shell or the new HyperOS, offer users a wide range of customization options. However, standard settings often limit the size of the subscriber’s image during an incoming call, leaving most of the screen occupied by control buttons or blurred backgrounds. This can cause discomfort, especially for people with impaired vision or those who just want to see the face of the caller as clearly and large as possible. The standard telephony interface is not always intuitively clear in terms of scaling, which raises many questions for device owners.

The problem with a small photo is not so much the technical limitations of the display as the logic of the Phone system application and the visual theme chosen. In some cases, the image is compressed by the system algorithms to maintain style uniformity, and in others, the low resolution of the busiest photo is to blame. The key here is the aspect ratio of the picture and its resolution, which must meet the high standards of modern screens. Understanding these nuances will allow you to effectively manage the display of contacts.

In this article, we will take a look at all the ways you can make a photo of a caller as big as possible. We will look at both the built-in features of the system and the use of third-party themes that completely change the call interface. We will also focus on the technical requirements for image files, because often the problem is solved by simply replacing the photo with a better one. You will learn to bypass the limitations of the standard launcher and make your smartphone more personalized.

Technical requirements for contact images

Before you go to the interface settings, you need to make sure that the source material meets modern standards. Many users upload old, low-resolution shots to the phone book, which when zoomed on a 6-inch screen and at Full HD+ or 2K resolution look blurry or take up little space due to automatic framing by the system. Photo resolution plays a critical role in how it will appear on the full screen.

The optimal format for a contact avatar is a square image or portrait with an aspect ratio of 1:1 or 4:5. Android often crops photos to fit them into a round or square frame of the contact widget. If you want the photo to occupy the maximum area, the source file must be of high quality, preferably at least 1080×1080 pixels. Using vertical images in full growth can cause the system to trim the head or shoulders, visually reducing the importance of the image.

⚠️ Attention: Uploading photos from messengers (WhatsApp, Telegram, Viber) often leads to strong compression of the image. To install a quality avatar, always use the original file from the gallery, not copied from the chat photo.

Also, you have to consider that some system themes have very tight limits on the avatar's display area, ignoring the edges of the photo, and in such cases, even a 4K image can be displayed in a small circle in the center of the screen, so the quality of the source is only half the success, the second half depends on the style you choose.

💡

Use the photo editor on your phone to pre-frame the image in a 1:1 square before placing it in contacts, which will give the system the right benchmark for zooming.

Configure the display through the standard menu

The first step to increasing your photo is to check the basic settings of the Phone app. There are parameters in the MIUI and HyperOS shell that govern the appearance of the call card. Although a direct slider called Photo Size is rare, there are adjacent settings that affect visual perception. You need to go to the Phone app, click on the three dots in the upper right corner and select Settings.

The menu that opens should look for sections related to Inbound Calls or Makeup. This can be the option “Full screen mode” or “Show full screen photos.” Activating these features causes the system to ignore standard frames and stretch the image of the contact. If you have a Google call installed, the path may differ: Settings → Incoming calls → Full screen photos.

It is important to note that on different firmware versions (MIUI 12, 13, 14, HyperOS), the location of these items can vary. If you do not find an obvious size switch, try changing the theme of the design, since the standard theme "Classic" often has the most stringent restrictions. Changing theme is the most effective way to change the geometry of the call screen without obtaining superuser rights.

Using themes to change the call interface

The most effective method to dramatically increase contact photos is to install a specialized theme from the MIUI Themes store. Theme designers often create designs where the caller’s avatar occupies 80-90% of the screen, pushing the response and reset buttons to the edges. To find such topics in the Themes app, use the keywords “Full screen caller”, “Big” or “Minima photolist call”.

When choosing a theme, pay attention to the screenshots in the description. You should be interested in the incoming call screen. Many popular themes, such as iOS Style or various minimalist designs, by default stretch the image. Once you install the theme and apply it to the system, the call interface will change globally. Rebooting the device after changing the theme is recommended for the correct application of all graphic elements.

It is worth considering that some themes may not work correctly with certain models of smartphones, for example, hide the speaker or block the image with a bang camera. In this case, the topic can be quickly removed through the Settings menu → Topics → Profile → Topics. Experiment with different options, since visual style is a matter of taste, but functionally they solve the problem of magnifying the photo.

⚠️ Warning: When installing themes from third-party sources (not through the official store), be careful. Unverified files may contain errors in the interface code, which will cause the screen to freeze during the call.

The problem of imported contacts and messengers

A common cause of a small or missing photo is the way the contact is saved. SIM-maps, the system often cannot display high resolution images or does not show them at all, replacing it with a gray stub. SIM-The card has severe data limitations and is not intended to store high quality graphics files.

To solve this problem, you need to transfer contacts to your Google account or phone memory. SIM-So you can choose a place to save your map -- go to Google, and that allows you to link a full image from your gallery to your contact, which is synced across all devices. Contacts linked to your Google account are displayed by the system as a priority and with higher quality.

Also worth mentioning is the integration with instant messengers. Xiaomi phone settings have a feature to display photos from Viber, WhatsApp or Telegram when calling. However, these photos are often low resolution, as messengers compress them. In the Phone app settings, find Contact Pictures or Number Identification and check which sources are allowed. Disabling low quality and prioritizing the local gallery can improve the situation.

Third-party applications for call management

If the usual tools and themes don't work, Google Play Store apps come to the rescue to replace the standard caller, programs like Truecaller, Call App - Caller ID & Block or ExDialer offer their own interfaces, where the photo size can be adjusted manually or it takes up the entire screen by default, and these applications take over the incoming call processing, overriding the system interface.

Installing such software requires broad permissions: access to contacts, phone, overlay (above other windows). Once configured in the application, you need to install it as the default application for making calls. This is done through system settings in the "Applications" → "Default Apps" → "Phone".

Using third-party calls has its advantages, such as improved spam identification and flexible look and feel settings. You can choose an in-app theme where the photo is huge and the buttons are translucent. However, remember the resource consumption: these applications can consume more battery power than the system counterpart.

Eliminating visual artifacts and bugs

Sometimes a contact photo looks small not because of the settings, but because of a software crash of the contact cache. If you change the photo to a large one, and it appears as a thumbnail, try clearing the cache of the Contacts and Phone app. → Annexes → All applications → Contacts → Clean up → Cash. Repeat the same operation for the Phone app».

Another reason could be a specific Android version or shell bug, which can be a switch between the design speed (light/dark theme) that causes the system to redraw the interface, and check if Simplified Mode or Senior Mode is enabled, which can force the size of interface elements to change, sometimes at the expense of graphics quality.

💡

Clearing the cache of the Contacts and Phone apps solves 90% of problems with incorrect display of avatars after updating the system or changing the topic.

If none of the methods worked, maybe the problem lies in the specific image file. Try converting the photo to a different format or resizing it in the graphics editor, making it slightly less than the maximum screen resolution so that the system does not apply automatic compression.
