How to zoom in on the screen of the Xiaomi Redmi phone: from font to system zoom

Problems with fine text or interface elements on Xiaomi Redmi are familiar to many users, especially for owners of devices with large screens (6.5" and above) or for people with visual disabilities. MIUI Offers several ways to zoom in, from basic font size change to gesture-controlled system zoom.

In this article, we will look at all the available methods, including hidden settings that are not obvious at first glance, you will learn how to configure scaling for specific applications, activate the magnifying function for detailed viewing, and what to do if the standard methods do not work. We will pay special attention to the differences between versions. MIUI 12/13/14 and nuances for older Redmi models (for example, Redmi Note) 5 or Redmi 7).

If you want to zoom in quickly in on your browser or messenger, you just need to use the finger-switching gesture, but to scale the whole system globally, you need to dive into the special features settings. Next, we'll look at each method in detail, with step-by-step instructions and screenshots.

1. Increase the font size and interface elements

The easiest way to make text and icons bigger is to change the system settings of the display.This method does not affect the scale of the applications, but significantly improves the readability of menus, notifications and main elements. MIUI.

Open the Settings. → Screen. → Text size and display. Here you'll find two key parameters:

• 📏 Text size – adjusts only the font (from “Little” to “Very Large”). Suitable if you need to zoom in on menus and notifications, but keep the icons compact.
• 📱 Display scale – changes the size of all interface elements (icons, buttons, input fields) and is not available on all Redmi models (for example, not available on Redmi). 9A s MIUI 12).

In the models with MIUI 14 (e.g. Redmi Note 12 Pro)+) There's an option called Screen Density in the developer menu that allows you to zoom in more accurately, but requires you to activate the developer mode (more on that below).

⚠️ Note: When choosing the "Very Large" value, text may not fit in standard notification windows, such as WhatsApp or Telegram messages will be cropped, in which case we recommend using system zoom (section 3).

Activation of the Screen Scale function (system zoom)

If the increase in font is not enough, in MIUI There's a built-in zoom feature that works like a magnifier, and it allows you to zoom in on any part of the screen with gestures without changing the settings of the apps.

To turn it on:

1. Go to Settings → Special Opportunities → Increase.
2. Activate the screen scale switch.
3. Select the type of control: 👆 Triple touch – zoom is turned on after three quick taps on the screen. 🤏 Scaling gesture – increase finger mixing/dilution (as in the camera).

Set the increase level (from 1.2)× 8×).

It works in all apps, including Chrome, Instagram and games, but there are some nuances:

• 🔄 When using a gesture, the zoom is triggered with a delay ~0.5 seconds (Protection against accidental activation).
• 🎮 In some games (for example, PUBG Mobile zoom may conflict with control – turn it off before a game session.

Insert the function in “Special Opportunities” |

Choose a convenient way to activate (gesture or triple touch)|

Check the work in key applications (browser, messengers)|

Turn off the zoom before gesture-controlled games-->

3. Local magnification in the browser and applications

Many applications have their own scale settings that are independent of system parameters.

Browsers (Chrome, Mi Browser, Firefox):

• 🌐 In Chrome: Open the menu (⋮) → Click Scale and select a value between 50% and 300%. Ctrl combination + + (On the physical keyboard, it also works.
• 🔍 In Mi Browser: swipe left/right across the screen for quick zoom change (Smart Zoom feature").

• 📚 In Google Play Books: Click on the Center of the Screen → Select the Aa icon to change the font size and line spacing.

⚠️ Note: In some banking applications (e.g. SberBank Online or Tinkoff), system zoom may be blocked for security reasons.

4. Hidden settings: screen density (DPI)

For advanced users who need to scale more accurately, the MIUI There is a hidden parameter - the density of the screen (DPI). Changing it allows you to reduce or increase all interface elements at the system level, including button sizes and distances between them.

To access this setting:

1. Activate Developer Mode: Go to Settings → About Phone. Click 7 times in a row on the MIUI Version (you will be notified "You are a developer").

Additional settings → Developer parameters

Change of change DPI This can cause some applications (e.g., banking or gaming) to display incorrectly!

5. High contrast mode and color filters

If the problems with the perception of the text are associated not only with size, but also with colors (for example, with color blindness or photophobia), in MIUI There are additional tools:

High contrast mode:

• 🖥️ Go to Settings. → Special facilities → Visibility → High contrast.
• Activate the switch. All interface elements will be black and white with clearly defined boundaries.
• 🔄 In this mode, the text becomes bolder, and the background is monotonous, which improves readability in bright lighting.

Color filters:

• 🎨 In the same menu (Visibility) select Color Correction.
• Pre-installed filters for colorblind people (protanopia, deuteranopia) or manual tweaking of shades are available.
• 🔴 For example, the red-green blindness filter makes red text more visible on a green background.

These features are especially useful for users with astigmatism or photophobia, as they reduce eye strain without changing scale.

💡

If you need to temporarily enlarge text at night, turn on night mode (Settings) → Screen. → Night mode) and set the color temperature to a minimum (1900K). This will reduce the blue component of light, reduce eye fatigue and visually make the font contrast.

6. Scale increase for individual applications

V MIUI 13/14 So we've got a custom zoom feature for apps, which allows you to, for example, only zoom in text on WhatsApp without affecting the rest of the system.

3. Press Permissions. → Special access → Change the size.
4. Activate the switch and select the increase factor (up to 150%).

Limitations of function:

• ❌ Some apps (such as TikTok) ignore these settings due to the protected display mode.
• ✅ Best supported in Chrome, Gmail and standard Xiaomi apps (Camera, Gallery).

⚠️ Attention: After updating the app through Google Play, individual scale settings may reset!

Alternative solutions: third-party applications

If the built-in functions MIUI Not enough, you can use third-party utilities:

Zuma applications:

• 🔍 Magnification Gestures (free, Google Play) – allows you to customize gestures to zoom in on any part of the screen with a factor of up to 10×.
• 🔎 Big Launcher – a simplified launcher with large icons and font, optimized for older users.

Tools for change DPI:

• 📱 App Settings (requires root rights) – allows you to change DPI for each application separately.
• 🛠️ BuildProp Editor – Edits the build.prop system file for global scale change.

Warnings when using third-party utilities:

• 🚫 Root-access applications can disrupt the work MIUI and lead to bootloop (load looping).
• 🔒 Some banking applications (for example, SberBank) block work on devices with changed system parameters.

💡

Third-party scaling applications should only be used if built-in features MIUI Start with secure root-free tools (such as Magnification Gestures), and only if necessary move to more complex tools.

8.Problem fix: Zoom doesn't work or resets

If the zoom resets after setting up or the zoom function is not activated, check the following points:

Problem 1: Zoom turns on but immediately shuts off

• 📱 Check if the One Hand mode is activated (Settings) → Additional settings → One hand - it can block zoom gestures.

Problem 2: Scale resets after reboot

• 🔧 This is a typical mistake on Redmi with MIUI 12.5 Update the firmware to the latest version via Settings → The phone. → Updating the system.
• 📲 If the update doesn’t help, reset the special features settings: Settings → Special facilities → Reset.

Problem 3: In some applications, the zoom does not work

• 🔒 Secure content applications (banks, payment systems) block system zoom. Use their built-in scale settings.
• 🎮 In games, zoom can conflict with controls. Try changing the sensor sensitivity in the game settings.

If none of the methods worked, reset the screen settings:

Settings → System → Resetting settings → Resetting display settings →
