How to Remove Rounded Corners on Xiaomi Screen: The Complete Guide

Owners of modern smartphones Xiaomi, Redmi and POCO often face visual effects that can be annoying when using certain applications or games. Rounded interface angles are a standard feature of the MIUI shell and the new HyperOS, designed to harmonize the image with the physical edges of the display. However, not all users like it when content is cropped or visually distorted due to software constraints.

Many people wonder if you can bring back the classic rectangular shape of the display to the entire matrix area. The answer lies in the deep system settings that are hidden by default from the average user. In this article, we will take a detailed look at all the available methods, from simple switches in the menu to the use of special codes of the engineering mode.

It's worth noting that changing these parameters affects how you experience content in general, and that the interface becomes more rigorous, and in some cases, it solves the problem of readability at the edges of the screen. Below are proven ways to solve the problem.

Nature of rounding: software or physical limitation

Before you make any changes, you need to be clear about the difference between physical and software constraints. Physical curvature is a feature of the screen matrix itself that you can't programmatically change. If your Redmi Note or Xiaomi Mi smartphone has curved glass edges initially, you can't software-based it, you can only adapt the display.

Software rounding is a feature of the operating system that puts black or translucent masks on the corners of the display. MIUI and HyperOS do this to create a uniform visual style, and that's the layer that we're going to try to disable or modify, and in some cases, the system itself determines the type of screen and applies the appropriate profile.

⚠️ Attention: Attempts to change the system configuration files of the screen (for example, through root rights) can lead to incorrect display of the image or complete failure of the touch screen.

It is also important to consider that the availability of features may differ on different models. Budget models of the Redmi series often have more stringent restrictions in display settings compared to the flagship lines.

Display settings in MIUI and HyperOS

The first and most secure way is to use the standard settings, and Xiaomi developers are gradually introducing the ability to manage this setting into the basic menu, so you have to go to Settings, then select Screen or Display, and this often hides the basic levers of visual style management.

Newer versions of the HyperOS shell have an option to adjust the size of the display area. Algorithms can offer multiple profiles: "Default", "Enlarged" or "Full screen". Selecting a full screen profile often automatically removes unnecessary indentations.

If you don't have a standard switch, try resizing the font or zooming in. Sometimes it indirectly affects the margins, and it's also worth checking the theme settings: some third-party themes force the geometry of the interface to be changed, ignoring system preferences.

• 📱 Go to Settings. → Screen. → Text size and display.
• 🎨 Check out the active theme in the Topics app and try the standard one.
• 🔄 In the About Phone section, click on the version several times. MIUI, To see hidden options (if available).

Remember that after changing the settings, you may need to restart the device to take effect. The system must recalculate the interface rendering parameters.

Use of engineering menus and codes

For more advanced users, there is access to hidden features through the engineering menu, which is a powerful tool that allows you to control the display parameters at a low level. To get there, open the Phone app and type in the combination ##6484#. CIT-menu (Cit Test).

Inside the menu, you need to find a section associated with Display or Version, and there may be parameters that calibrate the screen and the safety zone, but be very careful: changing the wrong setting can cause a touchscreen to malfunction.

adb shell wm overscan 0,0,0,0

This command, executed via a computer and USB debugging, is one of the most effective ways to remove software indentations, and it resets the overscan settings to zero, often returning rectangularity to the corners.

⚠️ Note: Entrance to the engineering menu is for service engineers. Do not change the values that are not 100% sure, as this may require flashing the device.

If you do not have the ability to connect your smartphone to a PC, you can use terminal emulator applications, but they will still require root rights, the receipt of which deprives you of guarantees.

Change of region and settings for developers

One of the little-known features of Xiaomi firmware is that it depends on the region it chooses. The Chinese firmware (CN) and Global firmware (Global) can have different restrictions. Sometimes changing the region in settings (Settings → Additional → Region) to India or Singapore will unlock hidden interface options.

You should also look at the Developer Menu, and to activate it, you need to click 7 times on the build number in the About Phone section, and within that menu, look for items related to zooming or forcefully resizing the screen.

Changing the minimum width is the most effective method without root rights. Increasing the value makes the interface elements smaller, thereby pushing content further from the rounded edges, visually straightening the angles.

After experimenting with DPIs, the interface may become too small, in which case just return the original value that the system usually shows in parentheses next to the input field.

Third-party launchers as a solution to the problem

When system methods fail, third-party shells come to the rescue. Launchers completely replace the desktop and often ignore the system's limitations on corner rounding. Popular options like Nova Launcher, Lawnchair or Microsoft Launcher allow you to flexibly configure the grid and indentations.

In the settings of such launchers, there is often a Form Factor or Corner Radius item where you can manually set the rounding value to 0 pixels, which causes icons and widgets to appear strictly rectangular, creating the illusion of no curvature throughout the system.

However, it is worth remembering that the launcher does not affect system dialogues, notification curtain and settings menu. The effect will be partial, but for desktop and application launch this may be quite enough.

• 🚀 Install Nova Launcher from Google Play.
• ⚙️ In the launcher settings, find the Desktop section.
• 📐 Adjust the indentations of the grid and remove the rounding of icons.

Some users go further and install modified versions of system applications, but this requires unlocking the bootloader, which is not recommended for regular users.

Adapting content in applications

Often, the problem of rounded corners occurs in specific applications, especially video players or games, in which case you need to look for settings inside the application itself. Many video players (VLC, MX Player) have a zoom feature that allows you to stretch the video to the full screen, ignoring the black fields.

In games, things are more complicated. Android gives developers an API to determine the safe zone, if the game is written with modern screens in mind, it will cut the edges itself, and if the game is old, it can be displayed in a small rectangle in the center.

Xiaomi’s screen settings have a memory extension feature (not to be confused with RAM), but there’s also a full screen setting. Go to Settings → Screen → Full screen mode and make sure the desired application is included in the list. This will force the system to stretch the application over the entire matrix area.

💡

For YouTube or browser videos, use the Full Screen function inside the player and rotate the device horizontally – in landscape mode, the rounding is often less noticeable or absent.

There's also the option of forced scaling for older applications through the developer menu, Scale to full screen, which will stretch the image, but can lead to distortion of proportions.

Frequent Questions and Challenges (FAQ)

💡

The main conclusion: Completely physically change the shape of the pixels can not, but the combination of changing the DPI, full-screen mode and the right themes allows you to minimize the visual effect of rounding.

To sum up, the struggle for a rectangular screen on Xiaomi is about finding a balance between aesthetics and functionality. Use these techniques carefully and your smartphone will become more convenient.
