"Apple&amp;#039;s iPhone 5S is facing delays due to issues with the device&amp;#039;s rumoured fingerprint sensor, according to a report. Reuters claims that the handset could miss its proposed summer unveiling because the firm is struggling to find a coating material that does not interfere with the fingerprint-recognition technology.   Previous reports suggest that the next-generation smartphone will be not be radically different to the iPhone 5, with a specs upgrade and the fingerprint sensor being the key differences. The news agency&amp;#039;s sources also fuelled rumours that Apple is working on a budget iPhone to gain a foothold in developing markets, adding that the cheaper handset will sport a 4-inch display and plastic coating. A photograph of what is said to be the casing of the budget iPhone appeared online last week, but its authenticity remains unconfirmed. Apple is also hard at work on the next iteration of its mobile operating system, with iOS 7 rumoured to be a dramatic overhaul of the user interface. "^^<http://www.w3.org/2001/XMLSchema#string>
