You may have forgotten that Whatsapp will no longer support older phones by January 1, 2017.
This development will force millions of people to upgrade their handset if they want to continue using it.
The popular messaging app has over a billion users, but will stop working on certain mobiles because of advancement in technology.
WhatsApp had said: â€œAs we look ahead to our next seven years, we want to focus our efforts on the mobile platforms the vast majority of people use.
â€œWhile these mobile devices have been an important part of our story, they donâ€™t offer the kind of capabilities we need to expand our appâ€™s features in the future.
â€œThis was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp.
â€œIf you use one of these affected mobile devices, we recommend upgrading to a newer Android, iPhone, or Windows Phone before the end of 2016 to continue using WhatsApp.â€
The app will stop running â€œat the end of 2016â€ on a variety of models, including iPhones, Android phones and Windows phones.
The chat app will soon stop working on the iPhone 3GS â€“ the second ever model released in 2009.
The update will also affect devices running older operating system iOS 6. Also, any iPhone 4, 4S or 5 or iPad that hasnâ€™t been updated to iOS 10 will be affected.
For Android phones, phones or tablets running Android 2.1 or 2.2 wonâ€™t be supported by 2017.
WhatsApp will no longer be supported on Windows Phone 7 â€“ users will need a minimum of Windows 10 Mobile or Windows Phone 8.1 to continue using it.
On BlackBerry phones? Whatsapp will work, although, it was originally planned to be dropped but WhatsApp will still support BlackBerry until June 30, 2017.
As for Nokia phones, ItÂ will still support Nokia S40 and Symbian S60 until June 30, 2017.
