How does htc mobile phone send WeChat QR code from SMS?

This is very simple! 1. First, find the QR code to be scanned on it, click to browse the QR code picture, then hold the picture for a long time, select "Save to" in the menu that appears, save the QR code picture on it, return to the page, click "Discover", then select "Sweep" to enter the scanned page, click the button in the upper right corner, and then select "Select QR code from album" in the menu that appears. Find the QR code picture you just saved, select it and scan it. If it is a group, you can join the group after the scan is successful. If you are unfamiliar, it is best not to enter easily. I'm afraid there's something incredible, a virus.
