As its first order of business, iOS 11.0.3 resolves a problem where an iPhone 6s user’s touch panel could become unresponsive if it were replaced previously by a third-party vendor. As a side note, Apple recommends that these users seek genuine Apple replacement parts and service to meet the desired performance expectations without any hiccups.
As with every one of Apple’s software updates, iOS 11.0.3 is available from our downloads page, and if you’re not jailbroken, you should consider upgrading to have the latest improvements to iOS.
