WhatsApp, although it seems something new, is an application that has been with us for 8 years. In its short life it has been available in operating systems such as iOS, Android, Windows Phone Symbian or Blackberry OS. Currently, the app is no longer compatible with very old versions of these systems, and from next January 1, 2018 will cease to be in more recent versions.
This year it stopped working in some operating systems
At the beginning of 2017, WhatsApp stopped being compatible with operating systems such as Symbian S60, Android 2.1 Eclair and 2.2 Froyo, iOS 6 or iPhone 3GS, and Windows Phone 7.1. Thanks to this, the company avoids having to make its application compatible with these old versions, and by eliminating legacy code you can save a few megabytes of application size , as it happened then. In addition, with this they can explore new functions in the future without fear of leaving behind other operating systems.
Thus, as of January 1, 2018, they will also stop supporting BlackBerry OS and 10, as well as Windows Phone 8. On that date, WhatsApp will block the possibility of creating new accounts, as well as being able to verify existing ones. However, you can still use the app, but can not update it or receive new functions because it will stop making the application compatible with these versions.
Windows Phone 8.0 and Blackberry 10 say goodbye to WhatsApp
In the case of Windows Phone 8.0, this version was released on October 29, 2012, and was the one used by very popular mobile phones at the time, such as the Samsung Ativ-S, or the Nokia Lumia 920 and 820, as well as the Lumia 620. This version has not been supported since May 2016, and was replaced by Windows Phone 8.1, version released in April 2014 and carried by mobile phones such as Lumia 930 or 530.
With BlackBerry, it will also stop being supported until the latest version of BlackBerry 10, whose latest version was launched just one year ago in November 2016. However, the last mobile with this operating system was launched in April 2015 (BlackBerry Leap), after the company decided to make the final leap to Android.
The following operating systems that will no longer support it will be Nokia S40 (until December 31, 2018), while Android 2.3.7 will no longer have support for WhatsApp on February 1, 2020. The recommendation of WhatsApp is to use at least Android 4.0 or later, iOS 7 or later, or Windows Phone 8.1 or later, in order to avoid problems with WhatsApp in the coming years.
If you have an old mobile phone with these operating system versions and you buy a new mobile, you will simply have to install the application in the new one using the same phone number you used before, so you can continue using your account. With this system, unfortunately, you will lose all your chats, although you can always export the history.
