Starting with the iPhone 6+ and continuing on the 7+, I experience more typing errors than on my former smaller-screened iPhones (e.g. my trusty fallback-somehow-collector's-item 4S, but also on 5 and 6 with their smaller screens). All of that with comparable typing speeds on comparable topics. Does anyone else experience something similar? First I was questioning my typing skills. Later I was questioning Apple's quality control for the digitizer, suspecting they'd been going for a cheaper component. Until recently some MR article about the creation of the iPhones revealed the concept of virtually upscaling the touch area of single keyboard buttons based on some predictive algorithm. Now I'm suspecting the 5.5" phones getting a smaller upscale of keyboard button touch areas in comparison to smaller iPhones. I somehow can't imagine the digitizer actually being of significantly worse precision than earlier digitizers in iPhones of the past. Can anyone confirm or falsify this theory? Is there any configuration option to manually adjust the zoom factor for those virtual touch areas?
