WhatsApp’s functionality evolved tremendously in the last four years.

Due to this reason, their decision of withdrawing their version for old software it’s not exactly a surprise.

WhatsApp has always been a cross-platform chat application. Shortly after launch, the version was conceived to especially run on devices with Symbian, Windows Mobile, Android, iPhoneOS, BlackBerry OS and so on.

Meanwhile, the functionality of the chat app diversified.

Now you can initiate VoIP calls via WhatsApp and you can see your friends and family in HQ videoconferences.

As expected, besides a faster internet connection, new features require an increased processing power.

WhatsApp creators have made numerous announcements in 2016 that rumored the popular app will not work on some devices.

With some of them, the application decided to prolong their collaboration and continued to provide support.

If WhatsApp has stopped working yesterday on your phone, the terminal is likely to be on the list of the affected smartphones.

Application developers have made the first announcement on this subject in February last year, but at the same time, the information is not very helpful.

‘While these devices have been an important part of our story, they no longer offer options that we need to expand the functionality of the application in the future. “, reported Whatsapp

The list of devices affected by this new strategy includes any smartphone running on Android 2.1 or Android 2.2.

iPhones with iOS 6, especially iPhone 3GS cannot run on  WhatsApp. The same will happen for terminals with Windows Phone 7. Owners of BlackBerry devices with OS, Nokia Symbian S60, and S40 have time until June 30, 2017, to upgrade.
