I have installed the beta and the it actually feels pretty stable but it also feels almost exactly like iOS11, it is probably so stable as it is iOS11 with a some minor tweaks and improvements rather than a full blown new OS (IMO). It is only little things like swiping up on the X to close apps (which I keep forgetting!) and the notifications that point to it being a new OS. Other than the password feature which when it lands will be awesome. I am massively underwhelmed and it really feels like Apple do no innovate like they used to, in so many areas iOS is falling further and further behind Android and the things that still irk me in iOS12 are: 1. Still no ability to customise your home screen (icon position and size) Even allowing the icons to wrap from the bottom rather than the top would be an improvement, but no it looks like we have another 12 months of every iPhone screen looking the same 2. No always on display. 3. Other than force touch cursor swipe the keyboard still falls way behind Android. Why do apple continue to block really useful things like long press for symbols for example? Totally baffles me 4. No dark mode. This is no biggie really for me but it would look awesome if the iPhone X had it. 5. Animoji and Meemoji. Honestly they feel pointless but locking them to iMessage only just seems daft. Allowing people for example to share them via whatsapp or social networks would open them up to a wider audience and I'd bet would tempt some android users to switch too. 6. Would have liked them to reduce face unlock from a 3 or 4 stage process to 1 or 2. Currently You have to pick your phone up, wake the screen, wait for the unlock symbol and then swipe. I have found it very reliable but there is no doubt that it is significantly slower than a FPS. 7. AR??? Does anybody honestly really care about this? For me that was an embarrassing watch at WWDC 1,2 and 3 remain my biggest beefs if they fixed them I’d live with the rest but whilst I have an iPhone, Android continues to be daily driver now and looks like it will be for another 12 months at least. The longer I do this the more I move away from Apple’s services, I now use Google for contacts, Calendar and photos, I have cancelled Apple music too. 3 years ago I was a 100% apple guy all in, now I am not and if windows was not so terrible I’d also be considering other options to my Mac too. Maybe some other stuff will land with the next iPhones? But I feel more and more like Apple is run by a bunch of uncool Dads who think they know what is cool but really don’t, and I say that as an uncool Dad myself! Definitely feels like new blood is needed in senior positions at Apple. YMMV and thoughts welcome.
