Apple has issued the first update to its iOS 9 mobile device software to fix some early glitches, including one bug that froze the device on the "slide to update" screen.
The repairs, released today, addressed a handful of bugs, including a problem with alarms and timers that failed to go off and another that distorted the frame of a paused video.
Apple had taken extraordinary measures to make sure this version of the software that operates iPhones and iPads was as glitch-free as possible, following last year's problematic launch of iOS 8.
The Cupertino technology company said more than half of its users had downloaded iOS 9.
