How to write a text message with a black screen on your phone

You can download several text messages with special effects (such as colorful words, black screen, etc.) from the Internet. Then edit before sending. You can send it directly if the screen is black; you will see a small space before the text message with colored text. This is the reason for the special effect text message. You delete the irrelevant fonts. This space must not be deleted. Then edit the black and white text, send and receive. The reader will see it. Currently it seems that only Nokia can see it
