WhatsApp will stop working on some specific mobile devices, just as it has happened in the past with other platforms and smartphones.
As of February 1, 2020 , the application will not be supported by the operating systems IOS 8 and Android 2.3.7, or older versions of them.
The messaging service will only be supported by Apple devices running on iOS 9, or all others that do the same with Android OS 4.0.3.
Of course, there will be no problem whatsoever with all the later versions, as one can easily perceive.
WhatsApp Inc. -the responsible section of Facebook that it now belongs to- has announced that due to the termination of the app, some other features or apps associated with it may be affected after december 31, 2019.
This is not the first time this has happened, as WhatsApp has ceased to be supported by iPhones with IOS 7 in January 2019 and a little earlier, in December 2017, was disabled on Nokia S40 and S60, and on BlackBerries OS and 10.
Anyone who has doubts about whether the phone’s operating system supports the application, can refer to the device’s settings screen and check it out, or simply make the necessary upgrades if they are certainly available for their mobile phone.
