The oldest model on which iOS 11 can be installed is the world’s first 64-Bit smartphone, the iPhone 5s, manufactured by Foxconn and first released on September 20, 2013. Apple wasn’t the first company using a biometric identification system but the 5s was the first smartphone with a perfectly functioning approach, the fingerprint scanner.
iOS 11 will be a further powerful iteration of Apple’s operating system for iDevices.
More about OS compatibility …
Bug fixing is just one of the main reasons for updated OS versions. An important other area developers have to work on is security. There are two reasons for delayed security updates from the customer’s point of view:
- OS providers aren’t ready with fixing the vulnerability
- You are the
proudowner of one of the 18k different Android-based devices.
It’s all about fragmentation.
Fixing bugs is a complicated business. You have to test with multiple operating system versions, hardware vendor interface layers, hardware configurations, and network capabilities. The testing matrix for Android-based devices can be a serious challenge, impacting your product’s quality, time-to-market, and in the end, profitability.
That fragmentation is tough on developers, the folks who make apps you love. When you’re making software for so many devices, it’s difficult to make sure your app works well for each unique piece of hardware. It’s part of the reason why Android still tends to get updates much later than iOS does (except a minority of devices running pure Android).
Once Apple’s updated OS is out it can be installed on up to 5 generations of iOS devices. This will remain a dream for people using Android-based devices.
