WhatsApp earlier in the year had announced that it plans to phase out compatibility with older phones due to changes in technology.

As per the statement released in February, the message app had said that it would no longer support a few Symbian, BBOS, Windows, Android and iOS operating system versions.

"While these mobile devices have been an important part of our story, they don't offer the kind of capabilities we need to expand our app's features in the future," a spokesperson for WhatsApp said.

WhatsApp had then set December 31, 2016, as the last day for support for some older smartphones that are still in use.
