Hey all. When I got my iPad mini 4 at launch it suffered from quite a bit of lag. For example the app switcher stuttered. Safari also lagged when you touched the search field and the keyboard popped up. There were also a few instances but I can't remember off the top of my head. I returned it a few days later but have the opportunity to buy one at a really good price and was wondering if the lag had been fixed with software updates? If it still has the same issues I won't bother but I'd like to hope it runs like butter now because the hardware is pretty solid in it. Thanks.
