This decision means that there will be no new updates and security patches for owners of devices with these OS versions.

To find out whether a particular device is subject to this restriction, you need to visit the “About Phone” section (accessed through “Settings” on smartphones running the “green robot” and through “Settings” => “General” on iPhones).

Starting tomorrow, WhatsApp will be supported on operating system versions starting from

  • 5.1 for Android;
  • 12.0 iOS for iPhones;
  • 2.5.0 KaiOS for JioPhone and all others.

To use WhatsApp updates, you need to upgrade to a more modern smartphone. If this is not done, the messenger will continue to work, but the WhatsApp team cannot guarantee security.
