Those still using smartphones with Android 2.3 Gingerbread or iOS 7 and older should upgrade to newer devices if they want to keep their access to the WhatsApp communication application. The company's website has listed these two software versions on the list of those who will soon be without support, but there is no rush, since the date the app will be shut down on these devices is still far away.
On February 1, 2020, WhatsApp will stop support for all devices running Android 2.3.7 or older and iOS 7 or older. At that time, we will already have the iOS 13 and Android 10 versions on the market, so there are probably not many devices to fit these market parameters in use. In fact, there are not so many devices this way, and iOS 7 and Android 2.3 are still being used on less than 1% of the users of each platform
WhatsApp has also announced the end of support for devices such as iPhone 3GS or older and BlackBerry OS, which is out of service at the end of 2016, as well as for BlackBerry OS 10, which was unsustainable at the end of last year. Nokia S40 phones are scheduled to remain without access to WhatsApp on December 31, 2018.
The fact that older phones still support WhatsApp for the next two years does not mean they will have access to all of the platform's capabilities. Some features may be stopped before the deadline, while the new capabilities that the app will receive may not be on iOS 7 or Android Gingerbread
