Back in 2009 when popular messaging app, WhatsApp, was launched the mobile market looked a lot different from it does today.

70 percent of smartphones on the market at the time were running BlackBerry and Nokia operating systems. Apple’s App Store was just launched and Google and Microsoft operating systems were used on less than 25% of the mobile devices in 2009.

Fast forward to 2016 and these operating systems are run on 99.5 percent of the mobile devices sold. And as security threats increase, WhatsApp support for redundant operating systems have become a waste of resources. The company announced that it wants to “focus [its] efforts on the mobile platforms the vast majority of people use”.

By the end of 2016, the company will be ending WhatsApp support for the following mobile operating systems:

  • BlackBerry, including BlackBerry 10
  • Nokia S40
  • Nokia Symbian S60
  • Android 2.1 and Android 2.2
  • Windows Phone 7.1

WhatsApp explains that the decision to end support for these platforms was based on their lack of capabilities to support expansions and updates that might be made to messaging app in the future. The company explains that:

This was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp. If you use one of these affected mobile devices, we recommend upgrading to a newer Android, iPhone, or Windows Phone before the end of 2016 to continue using WhatsApp.
