The way my iphone 6 reloads the apps and the safari tabs is crazy, it's so unreliable, it keeps sending me back to the main screen of the app I was using too, very anoying specially when you are filling formularies, I know the iphone 6 has 1 gb of RAM and the ipad air 2 has 2 gb of ram, I'm really curious to know, do the 2 gb of RAM solve this reloading issue or it has nothing to do with RAM and it's just the way IOS8 works?
