WhatsApp is the most popular messaging app. It offers convenience and flexibility. And it is supported in almost all smartphones. But now it is time to look at your smartphone, not to check any message or email but how old it is. According to reports, WhatsApp will stop working on millions of smartphones by the end of 2016 unless they are upgraded. WhatsApp, with more than one billion monthly users, was phasing out compatibility with older phones in a technology upgrade.
The company has said that several older services would be discontinued in 2017. “For iPhone users, WhatsApp will stop working on any iPhone 3GS and will also stop being supported on any device running iOS 6,” The service will also stop on any first, second, third or fourth generation iPad that has not been updated. Users need to update to iOS 9.3 to use the service. Phones or tablets running on Android 2.1 or 2.2 operating system will not be supported after year end.
