By the end of 2016, the instant messaging app WhatsApp will no longer work on a number of the old or nearly dead operating systems.
WhatsApp said it is intending to focus on just 99.5% of the mobile market that is addressable. Therefore, it will drop support for the Blackberry OS, Blackberry 10, Nokia Symbian S60 and Nokia S40.
Along with those particular changes, the company added in a post online that it would drop its support for Windows Phone 7.1 and Android 2.1 as well as 2.2.
The company added that it was intending to boost its security features in its messaging service, and when it began, close to 70% of the smartphones used were Nokia or Blackberry, with iOS, Windows Phone and Android now representing 99.5% of the smartphone market.
In the period of seven days that ending on February 1, Google said that 0.1% of users of Android ran Froyo 2.2.
In January, the $1 per year subscription fee of WhatsApp was dropped. The company said the model for subscriptions did not work well due to a number of users not having a credit or debit card.
The company announced that it would not be introducing ads to make up for the shortfall in revenue. WhatsApp recently has had battled with regulators in telecom across the globe.
The two largest South Africa telecoms, Vodacom and MTN want to see more services regulated, while the telecoms in Brazil are upset with WhatsApp for offering its voice call and have sought to have the app be declared illegal.
WhatsApp stressed that Nokia and Blackberry operating systems were a very big part of its story from the beginning, due to so few devices now being used, it is not in their interest to keep updating the compatibility with those two operating systems.
