HTC has launched its new flagship Android smartphone.
The revamped HTC One features a bigger screen than before and louder speakers. But its most striking feature is a sensor on its back that allows the device to refocus photographs after they are taken.
The BBC's technology correspondent Rory Cellan-Jones tried out the handset and asked the firm's co-founder, Cher Wang, whether the new features were enough to turn around its fortunes.
