WhatsApp will no longer work on some phones from next year. The company says it is withdrawing support for older phones because these phones run systems that make WhatsApp vulnerable to bad actors.
For those using iOS devices, iOS 8 and older will no longer be supported. For Android users, if you have a device that’s running the version 2.3.7 or older, you better change it.
Windows phones got it bad as all Windows phones can’t support WhatsApp anymore. The deadline for Android and iOS is February 1, 2020. But for Windows phones, you have just some days to switch as the deadline is December 31, 2019.
