In case of Apple, the limit has been set at iOS 9 or lower. According to Facebook, which owns WhatsApp, smartphones using Android 4.0.3 or lower will not be supported by the messaging platform. However, the key thing to note is that the end of WhatsApp support will impact only those users which are using old versions of both the operating systems. The users who have not backed their chats also risk of losing it when the company implements the change.
From Monday (November 1), messaging platform WhatsApp will stop working on a number of Android (Google's mobile software) devices as well as Apple-made iOS devices.
