My brother just brought me his iPhone 5 saying it was doing something "weird." He swiped down to open spotlight and then hovered his finger over the keyboard (I would say ~1/2 cm - 1 cm away). Most keys were non-responsive, but the f key would constantly pop up, although it would often register as a "c" in the text field. It "typed" at an extremely rapid rate - as if you were pressing the button 10 times per second. It also did something interesting where it jumped out of Spotlight back to the second page of the home screen (where he had been) and then "swiped" to the first page of the home screen - again, without being physically touched. I thought it was a joke or something so I grabbed it and tried it myself - exact same thing happened. To be perfectly clear, my finger was NOT touching the screen, nor was it close enough that any sort of "static" or "bond" between us should have caused the phone to type (on a normal basis). We both tried the same thing on my 5s without being able to replicate it. I did a soft reset of his phone and the issue went away (he was annoyed because he wanted to get a video of it), but he said he had done a reset or just turned it off before and while it stopped doing it right then, in most cases it started again. I know most people will think I'm 1. crazy or 2. making this up, but in all seriousness does anyone have any idea what the problem is or have had it happen themselves? The issue with it is that it makes the keyboard unusable while it is "glitching" because it senses the proximity of your finger when you try to physically touch other keys and adds random f's or c's.
