The condition, discovered by developer Adam Wolk, arises when a user types a link into a WhatsApp messenger application.
Wolk found that, as the URL is entered into the message, WhatsApp pings the host server, checking for a valid page each time a new character is typed.
The WhatsApp agent will also be adjusted to transmit less information to the host server when checking a URL.
That is not to say that WhatsApp is going to get rid of URL checks altogether – nor should they.
This, say privacy advocates, creates some potential risks for users who believe they are on a fully secure connection when using WhatsApp.
WhatsApp u-turn means your chat application won’t stop working this month
as mentioned in WhatsApp had previously announced that older versions of Android, iOS, BlackBerry and Nokia devices would no longer be supported by the chat app.
The technology company advised users running WhatsApp on one of these devices to update their smartphone before the end of 2016.
As 2016 came to close, WhatsApp confirmed the chat app would no longer run on the iPhone 3GS, Windows Phone 7 devices, and phones running Android 2.1 or Android 2.2.
However the company updated its initial blog confirming it would extend support BlackBerry OS, BlackBerry 10, Nokia S40 and Nokia Symbian S60 until June 30, 2017.
The hugely-popular chat app announced the u-turn in an updated blog post.
