WhatsApp will continue to work until the end of the year on BlackBerrys, while for old Nokia phones came the extension until December 31, 2018
WhatsApp starting last year, and then several times in this 2017, invited its users to use the service with a recent version of Android and iOS. The developers had announced a permanent block by June on older Nokia and BlackBerry. Apparently everything has been postponed to 2018.
To be precise, WhatsApp has extended the deadline to update its outdated operating system or directly change device to next December 31, 2017 for BlackBerry users. Those who own one of the old Nokia will have an extra year to decide what to do, until December 31, 2018, before they can no longer use the famous messaging app. But beware, this extension applies to all those who have a Nokia smartphone running Symbian 40. Those who use Symbian 60 will see their phone become incompatible with WhatsApp in just under a week.
Compatible operating systems
To avoid alarmism, let's try to recap all the operating systems that WhatsApp currently considers as "compatible". For those who have an Android, a version 2.3.3 or higher is sufficient. For those who have an iPhone needs a version higher than iOS 7. If you have a Microsoft phone, make sure you have Windows Phone 8 or higher. For WhatsApp, it is essential that users have an operating system that is performant enough to guarantee users the highest quality of service. Especially in video calls.
