Apple's World Wide Developer's Conference (WWDC 2015) will start on 8 June 2015 and reports about what iOS 9 will offer have already started. According to a report in 9to5Mac ,iPhones and iPads will be able to run iOS 9 efficiently. The report adds that Apple has been testing "a core version of iOS 9 that runs efficiently on older A5 devices." With the release of a new version of iOS, the biggest problem is that users who are on older devices, find their iPhones and iPads start getting buggy and slow once they move onto the new version. When iOS 7 was rolled-out in 2013, which saw a significant change in the iOS OS in terms of looks and design, the iPhone 4 and iPhone 4S users had complained how their devices had become slow. Similarly when iOS 8 was rolled-out, users on devices like iPhone 5c, iPhone 5, etc complained how the 'Settings' app was constantly crashing. Apple's WWDC is where the company showcases both the next level of iOS for iPhones and iPads and the OS X software for its Macs. While the first glimpse of the OS is shown at WWDC, the roll-out usually takes place in September. The other big rumour around Apple's WWDC 2015 is that iPad will now support "dual-app viewing mode," a feature long-offered by Samsung's tablets. In addition to this, there will be multi-user logins supported for iPads. The iPad has seen sales falls in 2015, even as the iPhone 6 and iPhone 6 Plus have set the market on fire. Apple shipped 12.6 million iPads in the first quarter of 2015 as compared to 16.4 million in the same period a year earlier, according to data from IDC. Whether a dual-screen mode will convince more users to buy an iPad remains to be seen, given that phablets and even Apple's own bigger-screened iPhones have eaten into the tablet market.
