The answer of this question is quite simple, 3D Touch which is present only in iPhone 6s and 6s Plus, it can work only on these flagship phones. However, it seems that it is working only on 9.3.1 which is the current latest version of iOS. This happens because most users allow Siri to access to the Twitter Account and the other apps. This serious bug can be fixed by restricting access to certain apps. It can be done by going to Settings –> Twitter –> Siri’s Access, revoke the access to the app and the Siri can be restricted from accessing photos by heading to the Privacy Settings and then Photos. Earlier, unusual bug in iOS 9.3 was crashing iPhones when users opened links on Safari Browser or in Notes, Messages or other apps.
