How to install apps in iphone 4s in my mobile i see that apps are not compatible in my mobile phone i want to install apps in my iphone 4s
Welcome to iMore! It sounds to me like you’re running a very old version of iOS and running into app compatibility issues. You’ll want to make sure you’re running the latest version of iOS your device supports, which I believe is iOS 9.3.5. That should help but iPhone 6s was released over six years ago so you’re likely to run into issues regardless.
