How to increase the font in a game on Android: from system settings to root editors

Small font in mobile games is a common problem, especially on devices with high screen resolutions or for users with visual impairments. Developers often optimize the interface for standard display parameters, forgetting about the ability to scale text. As a result, game menus, dialogues and tips become unreadable, and the gameplay becomes less comfortable.

In this article we will look at all available ways to increase the font in a game on Android from basic system settings to advanced methods using ADB i root access. You'll learn which settings you can change without risking your device, and where you need to be careful. We will also look at unique nuances for popular games (for example, Genshin Impact or PUBG Mobile), where standard methods may not work.

1. Increasing the font through the Android system settings

The easiest and safest way is to change the font size at the operating system level. This method is suitable for most games, since many of them inherit system display settings. However, there is a nuance: some applications (especially with custom engines) ignore global settings.

To increase the font:

• 📱 Open Settings → Screen (on some devices Settings → Display → Font size).
• 🔍 Find the slider "Font size" or "Text scale".
• ➕ Move the slider to the right to enlarge the font. On some firmwares (for example, MIUI or ColorOS), preliminary options are available: “Small”, “Medium”, “Large”, “Very large”.
• 🔄 Reboot the device if the changes are not applied. immediately.

On devices with Android 12+ there may be an option "Screen scale" (Settings → Accessibility → Screen scale). It enlarges not only the font, but also all interface elements, including icons and buttons. This is useful if the text in the game is too small due to the high screen resolution (for example, on Samsung Galaxy S23 Ultra with resolution 3088×1440).

⚠️ Attention: On some devices (for example Xiaomi or Realme) changing the font scale can lead to text being cut off in games with a fixed interface. Before competitions, Free Fire or Call of Duty Mobile check that important elements (for example, the map or health indicators) are not moving out. data-i="66">☑️ Checking after changing the font

2. Accessibility settings (for the visually impaired)

If the system font enlargement did not help, use the accessibility tools. In modern versions of Android there is a function "Screen Magnification"that works like a magnifying glass for the selected one. area. This will not change the font globally, but will allow you to temporarily enlarge the desired area.

How to enable:

1. Go to Settings → Accessibility → Magnification.
2. Activate the slider "Screen Magnification".
3. Adjust the magnification factor (usually from ×1.2 to ×5.0).
4. In the game, triple-tap the screen (or use a gesture if configured) to activate the magnifying glass.

To permanently enlarge the text in the menu, the option "High contrast text" (Settings → Accessibility → Visibilityis suitable. It makes font bolder and clearer, which improves readability in sunlight or low light. However, this method does not affect the game HUD (for example, the labels on the map Clash of Clans will remain the same).

On devices Samsung there is an additional function "Show enlarge button"that adds a floating panel for quick scaling. This is useful for games with a lot of text, for example The Arcana or Episode.

3. Changing the screen DPI (for advanced users)

DPI (dots per inch) is the pixel density per inch, which determines how large the interface elements will be. Lowering the DPI value will cause the system and games to display text and icons larger. However, this method requires caution: incorrect settings can lead to application failures.

Ways to change DPI:

• 🔧 Through Developer settings:
  1. Activate developer mode: Settings → About phone → Build number (press 7 times).
  2. Go back to Settings → System → For developers.
  3. Find option "Minimum width" (or "Smallest width") and set the value 360dp or 400dp (standard - 411dp for Full HD).

adb shell wm density 360

adb shell wm density reset

After changing the DPI, some games may be displayed incorrectly (for example, sagging buttons in Brawl Stars or cropped dialogs in Honkai: Star Rail). To check compatibility, run the game in a window 16:9 —it’s easier to notice distortions.

⚠️ Attention: Changing DPI via ADB is reset after rebooting the device. To fix the settings, you will need root access or module Magisk (for example, App Settings). On some devices (for example Google Pixel), an incorrect DPI value may block access to Google Pay or banking applications.

4. Using third-party applications for scaling

If system methods do not work, try specialized utilities. They allow you to increase the font selectively - only in the games you need, without affecting the rest of the system. Let's look at the proven options:

• 🔍 App Settings (requires root or Magisk):

  Allows you to change DPI, resolution and scale for individual applications. For example, you can set it for Clash Royale DPI 320, and leave the standard value for other games.

• 📱 Big Font (without root):

  The application creates a virtual zoom layer on top of the game. Supports gestures for quick zooming, but may conflict with anti-cheats (for example, in Apex Legends Mobile).

• 🎮 Game Tools (from Xiaomi):

  Built-in utility on devices Xiaomi/Redmi/POCO, which allows you to adjust the screen magnification directly during the game through the floating panel.

Before installing third-party applications, check their compatibility with your version of Android. For example, App Settings does not work on Android 13+ without additional patches. Also note that some games (for example, Roblox or Minecraft) block launch when a modified environment is detected.

💡

If the game crashes after changing the scale, try clearing its cache (Settings). → Applications → [Game] → Memory → Clear cacheThis often helps to reset the graphic settings to default.

5. Manually editing game files (for advanced users)

If the game stores font settings in local files, you can change them manually. root access or APK decompilation capabilities. Let's look at step-by-step guide using the example of a game Honkai Impact 3rd:

1. Download APK editor (for example, APK Editor Pro) or use MT Manager.
2. Find the game folder in /data/data/[package_name] or extract the APK.
3. Open the configuration file (usually config.json, settings.xml or preferences.plist).
4. Find font-related parameters: font_size, text_scale, ui_scale.
5. Increase the value by 20–30% (for example, from 1.0 to 1.3).
6. Save the changes and reinstall the game (when editing the APK).

For games on Unity (for example, Among Us or Brawlhalla) you can change the parameter Canvas Scaler in files assets. However, this requires knowledge of the project structure and can lead to bans for modifying the client.

⚠️ Attention: Editing game files may violate EULA (license agreement) and lead to account blocking. For example, in Genshin Impact for changing client files they give permanent ban without the possibility of appeal. Before experiments, create a backup copy of the game data.

6. Alternative solutions: emulators and external devices

If none of the methods helped, consider alternative options:

• 🖥️ Android emulators on PC:

  In BlueStacks or LDPlayer you can zoom the game window to 200-300%. Also, emulators support adjusting DPI and resolution regardless of system parameters.

• 📺 Connecting to a TV:

  Use Miracast, Google Cast or cable HDMI (via USB-C) to display the image on a large screen. The text will become larger due to the increase in diagonal.

• 🔍 Using a magnifying glass or VR glasses:

  For games with AR/VR (for example, Pokémon GO), you can use devices like Google Cardboard with a zoom function.

If you play on a tablet (for example, Samsung Galaxy Tab S8), try turning on multitasking mode and launch the game in the window. Then increase the window scale - the text will become larger without changing the system settings.

💡

Emulators are the only way to increase the font in games with a rigidly fixed interface (for example, Candy Crush Saga or Homescapes), where system settings do not work.

FAQ: Frequently asked questions about increasing the font in games

Is it possible to increase the font in Genshin Impact without root?

The Genshin Impact font is rigidly fixed in the client files. The only working methods are:

1. Use emulator (for example, MuMu Player) and increase the window scale.
2. Connect the phone to the TV via HDMI.
3. Configure enlarging the screen in Android accessibility features (magnifier).

Any attempts to change the game files will result in to ban your account.

Why do some games not launch after changing the DPI?

Some games (especially on Unity or Unreal Engine) check if the DPI corresponds to standard values If you have set an atypical DPI (for example, 300 on a device with 480, the game can:

• Give an error "Unsupported device".
• Start with a black screen.
• Crash when loading.

Solution: return standard DPI or try intermediate values (for example, 400 instead of 360).

How to increase the font in PUBG Mobile?

In PUBG Mobile the font is configured through the game menu:

1. Open Settings → General → Font size.
2. Select "Large" or "Very large".
3. For HUD (indicators health, map) use Settings → Controls → HUD size.

If there is no option, update the game or check the regional settings (in some versions, for example PUBG Mobile KR, more options are available).

Will there be a ban for changing the font through ADB?

Changing DPI or scale via ADB in itself does not lead to a ban, since this is a system function of Android. However:

• If the game detects resolution mismatch (for example, in Call of Duty Mobile), it may block entry into ranked matches.
• In games with anti-cheat (for example, Free Fire), a non-standard DPI may raise suspicions, but a ban will only be given if modified files are detected.

Recommendation: return before competitions standard settings.

Why do some games make the font larger, but not others?

It depends on how the developers implemented the interface:

• 🔹 Games on standard engines (for example, Cocos2d-x) usually inherit the system font settings.
• 🔹 Games with custom rendering (for example, Genshin Impact on Unity with their own UI) ignore global parameters.
• 🔹 Emulators of older consoles (for example, PPSSPP) allow you to adjust the text scale manually.

Check whether the game has built-in interface settings (for example, in Stardew Valley you can change the font size c Options → Display).
