FAQ

  1. I changed to use a bigger font size, but some apps still show text in small font.

    Some apps hardwire the font size in the code so the font size won't be changed after Big Font changed the system font scaling factor. Please help to send an email to app developer about this issue.

  2. Why does Big Font require the root permission?

    Big Font only requires the root permission for Android 4.2 ~ 6.x devices for changing the system font size without you to manually restart the device.

    The root permission is also required if you'd like to add more display zoom ratios on Android 7.0 or greater devices.

    To enable this, please first check the "Root access" option by going to the Settings window.

  3. Why can't I find the "Zoom display" function?

    Due to the restriction of Android, this feature is only available on Android 7.0 or greater devices.

    In addition, this function can only be used when the Accessibility services permission is granted or on a rooted device.

  4. Why all "Ignored apps" options are disabled?

    Due to the restriction of Android, this feature is only available for Android 2 or 3 devices.
