Then you should go up Adjustments and next to the name you will see the QR code symbol. This option will allow another user just by scanning there to add us as a contact.
As already mentioned, it is a new option that will gradually come to users.

How to send images without losing quality
When a photo is sent by WhatsApp, the recipient receives a version with lower quality than the original. The loss of quality is due to the fact that the application itself compresses them automatically. The goal of this is none other than to reduce their weight so that they reach the recipient in a much faster way. That is, the user must sacrifice an aspect to achieve speed. But there is a method to prevent this from happening.

After having opened the conversation, the person should press the attach button, which is represented by a clip logo at the bottom right of the screen. In this area a pop-up window will open where the shipping options are displayed and it is here that the first relevant action must be carried out, since the user should not choose the Gallery option, but the Document option.
