If you still use a phone running older software, then its time to look for a messaging service that is not WhatsApp. Facebook-owned WhatsApp has decided to end support for a series of ageing software including Nokia Symbian and Blackberry 10 starting 30 June. Besides, it is also pulling support for older Android versions.
The company had ended support for older Android and iOS version in December last year. The list of devices running Blackberry and Nokia Symbian are slated to lose support by the end of the month.
The complete list of older software that won't run WhatsApp:
Nokia S40
Nokia S60
Blackberry OS
BlackBerry 10
Android 2.2 Froyo
iOS 6
Windows Phone 7
WhatsApp has explained that the above mentioned platforms don't offer the kind of capabilities that the app requires to expand features in the future. So, in case you own a device running one of these software, then it is recommended upgrading to a newer OS version, or to a newer Android running OS 2.3.3+, iPhone running iOS 7+, or Windows Phone 8+ so that you can continue using WhatsApp.
