Smartphone models with Android 4.0.4 or earlier will become incompatible with WhatsApp, as well as iPhones that have iOS 9 or earlier installed.
Around 43 models will be unable to use the encrypted messaging service starting from November 1st, 2021
The phones WhatsApp will no longer work on include:
Samsung Galaxy S3 Mini, Trend II, Trend Lite, Core, Ace 2
LG Optimus F7, F5, L3 II Dual, F7 II, F5 II
Huawei Ascend Mate and Ascend D2

If your smartphone is no longer compatible with WhatsApp then you will need to upgrade to a newer model which supports the messaging platform.
Your existing account will be re-enabled when you enter the same phone number associated with it.
Although you will not be able to transfer chat history between platforms, for example from Android to iPhone, you can still keep your chat history.
You will be able to do this by exporting your chat history as an email attachment before November.
