From time to time, WhatsApp deprives its applications of support for older versions of operating systems. The last time this happened was in December 2020. Now the team of the messenger, owned by Facebook, announced the upcoming discontinuation of support for a number of outdated operating systems.
According to the official WhatsApp FAQ page, the world’s most used instant messaging service will no longer run on Android 4.0.3 Ice Cream Sandwich, iOS 9 and KaiOS 2.5.0 as of November 1st of this year. After that, you need Android 4.1 Jelly Bean, iOS 10, or KaiOS 2.5.1 to use WhatsApp. In addition, the messenger team says that, regardless of the iOS version, the application will not work on jailbroken iPhones.
Since we are talking about the end of support for fairly old versions of mobile platforms, the vast majority of users will not notice the changes.
