WhatsApp is soon to stop working on millions of phones.
WhatsApp will cease to function on 49 makes of phone, including the iPhone 5 and 5c along with several Android models from Samsung, Huawei and LG.
Users will be notified with a warning message before the app stops working.
A statement from WhatsApp explaining the move said: ‘Devices and software change often, so we regularly review what operating systems we support and make updates.
‘These devices also might not have the latest security updates, or might lack the functionality required to run WhatsApp.
‘To choose what to stop supporting, every year we, like other technology companies, look at which devices and software are the oldest and have the fewest number of people still using them.
‘To update your operating system on an iPhone go to the ‘general’ settings and select ‘software update’.
