How does the font of mobile phone short message become smaller?

If you use a vivo mobile phone, you can adjust it according to the version of the mobile phone system:

Funtouch OS 9. 1 or below: the font of SMS interface can be independently enlarged and reduced (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.

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

The reason for this is the following：

1, and the font size is the uniform size of the system. You can adjust the font size of the system in Settings-Display and Brightness-Font Size.

2. You can double-click the information copy to enter the full-screen enlargement page to view the enlarged font. It is recommended to view the contents of large fonts in this way.
