WhatsApp application is freezing but the black dot is not the actual culprit here, there is a small hidden trick in this message. One such nefarious intentions are new buggy messages found on the WhatsApp Android app. People are forwarding a message on WhatsApp, which stops the functioning of WhatsApp if you tap that message.
The website also noted that there seem to be two variants of this WhatsApp message being forwarded.
WhatsApp has registered a new domain, "wa.me".
The message includes special characters that do not display visibly but are used to change text behaviour. This is not a hoax as many WhatsApp users experienced WhatsApp crash after tapping on the black icon.
This isn't the first time this kind of message bugs have emerged. It is only after you tap on the message that your WhatsApp app may crash or freeze. So if you receive a message saying "This is very interesting!" with a crying laughing emoji, then you'll probably have to restart your device.
"As with any message bomb, it involves sending and receiving a specially crafted message with hidden symbols in-between spaces".
Even though this bug is a new and it hasn't been going around for that long, the Android and iOS WhatsApp community is outraged.
The URL will automatically redirect you to the chat window and once the "Message" button is clicked, the web page plugs into WhatsApp Web to let you chat with the person whose number you type in the URL. Initially, this message just looks like any other message but potentially it is capable to affect your smartphone.
Fear not; the bug itself is harmless, and reports state that there is nothing malicious embedded within the message.
It is best to avoid such messages and delete it from your beloved smartphones.
