Every year the applications carry out important updates to continue meeting the needs of their users. In this context, some devices become incompatible with the new versions of the apps and some of them even stop working.
One of the main problems of not being able to run WhatsApp on a smartphone is not only losing the ability to talk to your friends, but also losing access to a multitude of very useful tricks for using the application, either to prevent our internal memory from being filled up unexpectedly or to maintain our privacy as much as possible.
It is important to note that the instant messaging application will continue to be available for devices Android with operating system 4.0.3 or later and iPhone with iOS 9 or later.
iPhone
iPhone 4 and earlier models: They can no longer use WhatsApp, as they are not compatible with iOS 9.
iPhone 4S: We must upgrade to iOS 9 to use WhatsApp.
iPhone 5, iPhone 5S and iPhone 5C: We must upgrade to iOS 9 and later to use WhatsApp.
iPhone 6 and iPhone 6 Plus: We must upgrade to iOS 9 and later to use WhatsApp.
So, if you have an iPhone 4 (or other earlier models), WhatsApp will stop working on your phone in 2021.
Android
WhatsApp will work on devices with Android 4.0.3 and further. Earlier models that aren’t able to run Android 4.0.3 will not be able to run Whatsapp also.
