How to increase the font on Xiaomi Redmi Note 8 Pro: all the ways from system settings to hidden chips MIUI

The Xiaomi Redmi Note 8 Pro remains one of the brand’s most popular smartphones due to its price-performance balance, but its 6.53-inch screen isn’t always convenient for visually challenged users. Increasing the font on this device can dramatically improve the experience of interaction from reading messages to working with the settings menu. However, standard MIUI options don’t always offer enough flexibility: maximum font size in system settings often seems insufficient, and third-party launchers can conflict with the branded shell.

In this guide, we will look at all the available methods for resizing fonts, from basic to advanced, including hidden MIUI 12/13/14 features, customization for individual applications and even modifications through ADB (no root rights!). Particular attention will be paid to the nuances of the Redmi Note 8 Pro with its unique hardware (Mediatek Helio G90T processor) and firmware versions where some options may be missing or work differently. If you encounter a problem of a “gray” scaling slider or distortion of the interface after changes, here you will find solutions.

1. Standard method: display settings in MIUI

The most obvious and safe method is to use built-in shell tools. On the Redmi Note 8 Pro, the path to font settings depends on the MIUI version, but the overall scheme is maintained:

1. Open the settings (cog icon on the desktop).
2. Go to the Screen (or Display in older versions).
3. Select Text Size (in MIUI 14, it can be called Font Size).
4. Move the slider to the right to zoom in. Available values: from Small to Large (in some firmware - to XXL).

⚠️ Note: Redmi Note 8 Pro with MIUI 12.5 and below, when choosing the maximum font size (Huge), you can see artifacts of display in system applications (for example, cropping text in Phone or Contacts). The solution is to use alternative methods from the following sections.

Check the version of MIUI in Settings → About the phone

Make sure the slider is not blocked (grey)

Close all applications before changing

Restart your phone after the changes are applied (recommended)

-->

MIUI 13/14 has a Display Size option (separate from font) that allows you to zoom in on all interface elements, including icons and buttons. However, activation of this option can lead to incorrect display of some stock applications (such as Camera or Gallery).

2. Change of font for individual applications

MIUI allows you to customize text size selectively, just for specific programs, which is useful if you like the system font, but in messengers or browsers, the text is too small.

1. Press the icon of the desired application on the desktop → select Application Information (or Information).
2. Tap on Permissions → Additional settings (in some versions of MIUI, the path may be different).
3. Find Text Size or Display Settings.
4. Set the desired size (values are available from 80% to 130%).

⚠️ Note: Not all apps support this feature. For example, in WhatsApp or Telegram, zooming works only for chat text, but not for interface elements (buttons, headers).

3. Use of the “visually impaired” regime

If standard font magnification isn't enough, MIUI has a hidden mode for the visually impaired that drastically changes the interface: it increases all the elements (fonts, icons, buttons) and makes navigation easier.

1. Open the Settings. → Special facilities.
2. Select Vision (or Screen Magnifier in older versions).
3. Activate the switch Mode for the visually impaired.
4. Set up the parameters: 🔍 The font size is up to 200% (unlike the standard 130%). 🖼️ Contrast text – makes the letters bolder. 🎨 Color filters are useful for color blindness.

⚠️ Warning: This mode turns off animations MIUI Some gestures (e.g. swipe to backtrack) may also have problems displaying in games and banking applications (e.g. SberBank Online may require you to turn off mode to work.

4. Third-party launchers with advanced font settings

If the built-in MIUI options don’t suit you, alternative launchers (like Nova Launcher, Action Launcher, or Microsoft Launcher) offer flexible text customization.

1. Install the launcher from Google Play and assign it to the main one (a sentence will pop up when you first start).
2. Select the free space on the desktop → Settings.
3. Go to the Appearance → Icon size and font size.
4. For the font, values from 85% to 150% are available, as well as a choice of custom fonts (.ttf files).

⚠️ Note: Redmi Note 8 Pro with MIUI 12.5 and below, when using Nova Launcher, scroll delays may occur due to conflict with shell optimizations for the Helio processor. G90T. Solution - disable animations in the developer settings (Settings) → The phone. → Version. MIUI (tap 7 times) → For developers → Scale of animation → Choose No Animation).

💡

If the font in some applications hasn’t changed after installing the launcher, try clearing their cache: Settings → Apps → Select a program → Clear the cache. This often helps with display conflicts.

5 Advanced Methods: ADB and System File Modification

For users willing to experiment, there are ways to change the font at the system level — without root rights, but using ADB (Android Debug Bridge), which allows you to bypass the limitations of MIUI and set an arbitrary font size (for example, 180% instead of a maximum of 130%).

⚠️ Attention: Misuse of the right ADB It can cause an interface failure or a reboot cycle. Before you start, back up your data through Settings. → Additionally. → Backup and reset.

Instructions:

1. Turn on USB Debugging: Settings → About Phone → MIUI Version (Tap 7 times) Settings → Additional → For Developers → Debugging on USB
2. Connect your phone to your PC and confirm your trust in your computer.
3. Open the command line (Windows) or the terminal (macOS/Linux) Enter: adb shell settings put system font_scale 1.5 where 1.5 — scale (1.0 = standard, 2.0 = double-size).
4. Reset the device.

To return the standard settings, run the command:

adb shell settings delete system font_scale

💡

ADB-method to circumvent the limitations MIUI, But it changes the font globally -- including system notifications and download menus.

6. Installation of custom fonts through TTF-file

If you are not satisfied with not only the size, but also the style of the font, you can install custom fonts in the.ttf format on the Redmi Note 8 Pro.

1. Download your favorite font (for example, from fonts.google.com or dafont.com).
2. Place the.ttf file in the Download folder on your phone.
3. Use the iFont app (available in the Play Market): 📁 Open the app and select Local. → find your file. 🔄 Tap it, set it up. → choose MIUI font. 🔧 Reboot the phone.

⚠️ Note: Redmi Note 8 Pro with MIUI 12.0.3 and below, installing custom fonts can cause system applications (e.g. Settings or Security) to crash. Check the font compatibility with Android 9 before installing. Also avoid fonts with Cyrillic characters in the file title - this can cause a parsing error.

Once installed, the font can be scaled with standard MIUI tools (see Section 1). Some custom fonts support dynamic boldness change as size increases, which is useful for improving readability.

7. Solving problems after changing font

Enlarging the font on the Redmi Note 8 Pro can lead to unexpected bugs. Here are the most common problems and solutions:

If after the changes the phone started to brake, clean the cache of the system:

Settings → Additional → Memory → Clear the cache

This helps in 80% of cases when the lags are caused by remodeling the interface to a new scale.

For the Redmi Note 8 Pro with 6 GB of RAM, critical brakes are unlikely, but on models with 4 GB (for example, the Redmi Note 8), large print can lead to launcher reboots.
