WhatsApp recently bade farewell to Windows Phone. The giant chatting app
is now ready to do the same with some Android and iOS devices. This is
not surprising as there have been talks about it for quite a while.
Starting
from February 1, 2020, WhatsApp will no longer work on phones running
Android 2.3.7 or iOS 7 (and earlier). So, if you are using an Android
phone running that Android version or earlier, then WhatsApp will stop
working on your phone from next Saturday. The same applies if you are using an iPhone 4 or an earlier model.
When
WhatsApp pulled the plug on Windows Phone, the app no longer started.
In fact, it was impossible to access the chat history. So, you may want
to save a backup of your chats before Saturday if your phone is running
any of the old Operating Systems. That way, you will have your important
conversations intact upon switching to a more updated phone.
