And now the company has announced that it will no longer support older versions of its app after January 15, 2017.
We hope that you’ll consider upgrading to our new app, which is available on the following mobile operating systems: iOS8 and higher (iPhone 5 and above) and Android Ice Cream Sandwich MR1 (4.0.3/API level 15).
The company also said in a statement, "Upgrading to the new app is easy - prior to January 15 you'll receive a pop-up when accessing the app that will prompt you to upgrade to the new version. After January 15 you can upgrade through either the App Store (iOS) or Google Play (Android). You can also access www.linkedin.com on your device’s web browser".
