Change Fonts LG G7: Step-by-Step Guide

Updated 7 November 2026 · Standard formula, shown below

You can change the font on your LG G7 ThinQ through the Display settings, where you can choose from a few pre-installed fonts or download new ones from the LG SmartWorld app. This guide walks you through the exact steps, explains the differences between font styles and sizes, and answers common questions about customizing text on this phone.

Why Change the Font on Your LG G7?

The LG G7 ThinQ runs Android 8.0 Oreo out of the box, and like most Android phones, it lets you adjust the system font to suit your reading preference. Some people find the default font too thin or too small, especially when reading long emails or articles. Others simply want a fresh look. Changing the font can also help if you have vision issues—LG includes a high-contrast font option and a separate display size slider that makes text larger without changing the font style.

Unlike some other Android phones, the LG G7 does not let you install arbitrary TTF or OTF font files directly through the Settings menu. Instead, you are limited to the fonts available in the LG SmartWorld store. This is a common point of confusion, so it is worth knowing before you start looking for APK files or third-party launchers.

How to Change the Font Style

Here are the exact steps to switch between font styles on your LG G7:

Open the Settings app (the gear icon in the app drawer or notification shade).
Scroll down and tap Display.
Tap Font (or Font style in some versions).
You will see a list of available fonts. Tap one to preview it on the sample text at the top.
Tap Apply (or OK) to confirm your choice.

The default font is usually called LG Smart Gothic or simply Default. Other options may include LG Smart Serif, LG Smart Headline, and Rosemary. The exact list varies by firmware version and region.

How to Download More Fonts

If the built-in fonts are not enough, you can get more from LG’s official app store:

Open the LG SmartWorld app (pre-installed on most G7 units).
Sign in with your LG account (or create one if you do not have it).
Go to the Fonts section (look for a “Font” category or search for “font”).
Browse the available fonts. Many are free, but some may be paid.
Tap Download on a font you like.
After downloading, go back to Settings > Display > Font and select the new font from the list.

Note that the font will only appear in the Settings list after it has been fully downloaded and installed. If you do not see it immediately, try restarting the phone or checking for updates in SmartWorld.

Adjusting Font Size and Display Size

Changing the font style is different from changing the font size. The G7 has two separate controls:

Font size: Changes the size of text in menus, apps, and notifications. Go to Settings > Display > Font size and drag the slider.
Display size: Changes the overall scale of UI elements, including icons and spacing. This is found in Settings > Display > Display size (sometimes under “Screen zoom”).

If you want larger text without changing the font style, increase the font size first. If you want everything—including icons—to be bigger, increase the display size. Be aware that some apps do not respect the system font size and may have their own text settings.

Common Problems and Fixes

Users often run into a few issues when trying to change fonts on the G7:

Font does not apply to all apps: Some third-party apps (like certain games or PDF readers) use their own fonts and ignore the system font. This is normal and not a bug.
Downloaded font does not appear: Make sure the font is fully downloaded in SmartWorld. If it still does not show, clear the cache of the SmartWorld app (Settings > Apps > SmartWorld > Storage > Clear cache) and try again.
Font size resets after reboot: This can happen if you are using a third-party launcher or a battery saver that kills background processes. Try setting the font size again after reboot, and check if any “power saving” mode is overriding display settings.
Can’t install custom TTF files: The LG G7 does not support installing fonts from file managers by default. You would need to root the device or use a third-party app like “iFont” that works with some devices, but this is not guaranteed and may void warranty.

Comparing LG G7 Font Options

The built-in fonts on the G7 are designed to be legible on the phone’s 6.1-inch QHD+ display. Here is a rough comparison of what you can expect:

LG Smart Gothic (default): A clean sans-serif font, similar to Roboto. Good for general use.
LG Smart Serif: A serif font with small tails on letters, giving a more traditional, book-like feel.
LG Smart Headline: A bold, condensed font that makes text stand out, but can be tiring for long reading.
Rosemary: A decorative, handwritten-style font that is not ideal for body text but can be fun for personalization.

If you want a font that is easier to read for long periods, the default gothic or a serif font is usually the best choice. Decorative fonts are best used for short messages or home screen widgets.

Safety and Warranty Considerations

Changing the font through the official settings or SmartWorld is completely safe and does not affect your warranty. However, using third-party apps that require root access or modifying system files can void your warranty and potentially brick the device if done incorrectly. Avoid downloading font APKs from unknown websites, as they may contain malware. Stick to the official LG store or well-known font apps that do not require root.

Frequently Asked Questions

Can I use any font from Google Play on my LG G7?

No. The LG G7 does not support installing fonts from the Google Play Store directly. Some font apps on Play Store claim to work, but they often require a separate launcher or a specific installation method. The only reliable way is through LG SmartWorld.

Will changing the font affect battery life?

No, changing the font style or size has no measurable effect on battery life. The phone renders text the same way regardless of the font, so there is no extra power usage.

How do I reset the font to default?

Go to Settings > Display > Font and select the default font (usually named “LG Smart Gothic” or “Default”). If you cannot remember which one it was, restarting the phone in safe mode (press and hold the power button, then tap and hold “Power off” until the safe mode prompt appears) will temporarily use the default font, but you still need to select it manually in settings.

Why is the font size slider not making text bigger?

Some apps have their own text size settings that override the system font size. Check the app’s own settings (often under “Settings > Text size” or “Display”). Also, make sure you are moving the “Font size” slider, not the “Display size” slider, as they affect different things.

Can I change the font on a locked LG G7?

No, you must unlock the phone and go through the Settings app. There is no way to change the font from the lock screen or without unlocking.
