I've read back through all the posts in this thread and I'm still trying to work out exactly what the problem is people are having with the zoom function in iOS 8?
I'm NOT doubting people are having problems. I'm trying to work out what the problem is. All the Zoom functions work as intended and seamlessly, in iOS 8.1 on my iPhone 5s.
I also have a visual disability, (optic atrophy), but my vision isn't so bad that I need to use VoiceOver, although I do find the new Speak Screen function in Speech quite useful at times.
I rarely use three fingers for Zoom anymore and instead I mainly use the Controller. It was a bit awkward to get the hang of it at first, especially scrolling, but now I think it's the best Zoom feature to date. It's so much easier navigating with one finger instead of three, especially on an iPhone screen. Everyone is going to be different of course, depending upon the type of visual disability they have and also the degree.
I changed the wallpaper on my home screens to a dots matrix Grey (one of the choices already in the phone), so that my apps and in particular the Controller are easier to see. And you can change the visibility of the Controller (more opaque / less opaque), or hide it completely using the black dialogue box that irritates ioannisfromaddison so much. No criticism intended!
I love the fact that it's a simple one finger tap on the Controller to turn the dialogue box on or off, and if the Controller is under the dialogue box tap anywhere on the screen to make the dialogue box disappear.
Double tap the Controller to zoom in or out to your previously pre-set zoom level.
Use the slider on the bottom of the dialogue box (if you're already zoomed in) to zoom in or out even more. You can also set a maximum zoom level in the Settings Zoom menu.
Once zoomed in, quickly swipe inside the Controller to make the Controller EXPAND, and then scrolling around the screen becomes a one finger walk in the park.
I have everything switched on in my Zoom Settings.
I can't help but wonder if some of the reported problems are caused by people adjusting their settings and then NOT following the correct path back to the Home Screen and thereby NOT saving the changed settings?
BTY if you must insist on using three finger zoom, I would turn off the Controller in Settings, not just hide it at the black dialogue box!
It's 2am, I'm tired, and I'm not sure what the tone of what I've just written sounds like, but it's not intended to offend anyone! Goodnight!
