Hi there! I understand that making the font larger can really help with readability—it's essential for a comfortable user experience. Let’s go through how you can increase the font size in the TeleGuard app on your Linux device.

### Steps to Increase Font Size:

1. Check App Settings:
- Open the TeleGuard app.
- Look for a gear icon or a menu option to access the Settings. This could typically be found in the side menu or by tapping your profile icon.

2. Display Settings:
- Once in Settings, see if there’s an option for Display or Appearance.
- Look for a Font Size or Text Size adjustment setting. If available, increase the size to your preference.

3. System Settings:
- On Linux, you can also adjust the system-wide font settings.
- Open your System Settings or Control Center.
- Navigate to the Display or Accessibility settings.
- Look for Font Size and adjust it accordingly. This will affect all applications, including TeleGuard.

4. Restart the App:
- After making the changes, restart the TeleGuard app to ensure the settings take effect.

If you don't find the options above, or if adjustments are not applying as expected, it might be beneficial to check for updates to the app or your Linux system, as sometimes compatibility improvements can enhance functionality.

### Additional Notes:
- If adjustments in the app settings do not take effect, you might consider resetting the app settings in the TeleGuard to see if it resolves the issue.
