I haven't noticed **** on my iPad Air or iPhone 6... This threads a few months old though so you new posters are you guys on iOS 8.1.2
I've applied a Tempered glass on it and it lost about 30% sensitivity when scrolling with the side of my finger. No noticeable difference before I applied it.
Exactly which product did you apply? I'd like to avoid it and may have to rethink putting glass on mine (I haven't done it yet, but was considering it).
It was a $10 one on eBay, I believe the name was "gorilla" not Gorilla Glass, which is what I think they were going for.
I've had glass on my mini and no loss in sensitivity, but it's very noticeable on the iPad air 2. Not sure if it's the glass or just the new display tech.
Noticed this as well. Drives me nuts.no sensitivity reduction, but have occasionally had a lack of response when clicking google links, pretty sure its an ios bug
