According to this statement, users whose smartphones run on Android 2.3.7 and iOS 8 operating systems will no longer be able to create a new account or confirm existing accounts. However, they can use the app until the specified date.
"Due to the fact that we do not plan to update these operating systems, some features may stop working on them at any time," the developers said in the release.
In addition, Windows Phone operating systems will be decommissioned after December 31, 2019, and the WhatsApp application may be unavailable in the Microsoft Store.
At the same time, messaging developers recommend using devices running Android 4.0.3 and iOS 9 operating systems at a minimum, or under the higher versions. In addition, they claim that the application will be available on some smartphones on the operating system KaiOS 2.5.1 and new versions, including JioPhone and JioPhone 2.
