iOS 9 is a day old now (exclude the Beta's) and the reaction is somehow negative. most of users complain about: 1- laggy performance 2- App crashes 3- slow compare to 8.4 (Facebook,Macrumors forum, Twitter, comments on websites) So this is not new all OS's launch is terrible at some point BUT when it comes to Apple I think we should point somethings: 1- There is so many Beta's before the official launch. and almost millions of people try those builds so why there is SO much problems? 2- If android launch a new OS and it face the problems I mentioned above we my give it an excuse because Android is running on thousands of devices old and new from Samsung, LG, HTC, Lenovo, Moto and an army of Chinese small companies. so the optimization is some how impossible you need extra developer hand to expand the optimization and tune it to the devices he make. but when it come to Apple.. there is only less than 20 devices planned to support iOS9 and they cant optimize it well to work! is it that's hard to test the OS in 20 devices? 3- Whats the different between iOS9 and iOS8? basically both the same with more features and updated apps and tasks! so the core of the OS is almost the same, Why the bugs and the lags? 4- Apple always say we are the best because we make the software and the hardware. but whats the point of that when your system is just as "buggy" on its launch as Google android on Xiaomi devices? Am Apple's biggest fan but I really start to think Apple should start thinking about hiring Scott Forstall back. I used OS 2,3,4 and never saw problems like what I saw in 7,8,9.
