WhatsApp will not work on some phones from tomorrow. Older Android – iOS phones may not get WhatsApp.
According to the source, the “WhatsApp” application will not work on iPhones that do not upgrade to operating system 9 and above, and on phones below Android 4.03.
Application manufacturers need to update their devices to these versions of their operating system. Those who can’t update either have to buy a new smartphone. Or find a new app to replace WhatsApp.
WhatsApp will not be available from next year for users of iPhone 4 or earlier models released by Apple. Users of the Samsung Galaxy S2 will also have this problem. WhatsApp will be discontinued in the coming days on phones like HTC Sensation, HTC Thunderbolt, Samsung Google Nexus S, Sony Ericsson Xperia and LG Optimus.
For iPhone users to get WhatsApp on their iPhone device you’ll need to upgrade your phone and then download WhatsApp.
System upgrades can be done easily by iPhone users. All you have to do is go to Settings and select General and update the software.
