At last, I thought it was only me suffering from an unresponsive touchscreen after updating to ios8.
I First noticed an issue when using the App Store app and trying for ages to open the rest of the text in the detail section of apps by pressing the 'more' link, nothing was happening.
I Realised that in order to get this link to activate I had to touch somewhere slightly above and to the left of the actual text.
I Have also noticed a slight pause when opening apps that need vertical scrolling, such as My Fitness Pal. It seems that it takes a couple of seconds after the app is opened before I can scroll up or down.
I Have also noticed that the Music & Podcast apps are sometimes frozen when opened, displaying that they are playing but actually are not playing & no matter how many times I try to hit the Play/Pause button nothing happens. I have to close the app and reopen to resolve.
SOmething else else I have noticed since ios8 is the almost totally useless Today screen on Notifications.
For one, most app widgets seem to work OK for a day or two but then stop updating i.e. News apps should always show latest headlines etc.... only removing these apps from the Today screen and then adding them back sparks them to life again.
I use a lot of reminders and these also show on the Today screen and since ios8 it is a nightmare when trying to click on a composted reminder here. Prior to ios8 it was easy, I clicked, the circle filled with a red dot and disappeared from the Today screen. Now because of responsive issues I press the circle like crazy and it keeps opening up the reminder app instead.
It would seem like the screen calibration is ever so slightly off.
Typing this post on my iPhone 5 has been almost painful as it keeps randomly inserting uppercase characters, especially capital 'A' & also occasionally deleting the last letter of word when double pressing the space bar for a full stop.
Come on Apple, pull your **** finger out & get this sorted.
Not a happy customer but a potentially future ANDROID one.
