Apple's latest software update for the iPhone and iPad tablet is causing popular applications made by Facebook, Dropbox and others to crash more frequently, according to a report.
Apple's iOS 8 operating system causes apps to crash about 3.3 per cent of the time, or 67 per cent more than last year's version, according to a report by Crittercism, an analytics firm that works with companies such as EBay, Martha Stewart Living Omnimedia and Yahoo.
Customers have taken to Apple's App Store to complain. One user wrote that Facebook's app - the way most of the social network's members access its service - "constantly freezes and crashes." Dropbox, a file-storage service, also has put out updates to its app to fix problems it was having with iOS 8.

Crittercism said older iPhones experience the most issues. Andrew Levy, the firm's chief executive officer, said Apple's latest software includes more than 4,000 new functions and changes, and developers are struggling to adapt.
