How to put a small SMS font in the body

The font of SMS interface can be enlarged and reduced independently (without affecting the font size of the system).

When the text message font becomes larger, open the information details interface, and hold down the screen with two fingers and slide relatively (the two fingers slowly close together) to reduce the font.

Note: OriginOS/Funtouch OS 9. 1 and later versions do not support this function.

The reason for this is the following：

1, font size is the uniform size of the system, and users can adjust the font size of the system in the settings.

2. Users can double-click the information copy to enter the full-screen enlarged page to view the enlarged font.
