One of these is the model Nokia S40, which will no longer be possible to use the application starting from 1 January 2019.
Likewise, the owners of a iPhone 4 (published in 2010) that has been updated only until iOS 7, will cease to work in February 2020.
This list also includes Android phones version of the operating system 2.3.7 Gingerbread or previous, which will also have WhatsApp only until February 2020.
WhatsApp will offer the ability to back up the conversation history via email or cloud storage, depending on the operating system.

This mechanism can be used in One Drive and iCloud cloud storage services.
