Now headaches? Really?
You forgot the green glow on the lock screen and the purple haze on the camera. I'm sure Safari is also less snappier.

I've felt the same when I got my iPhone5. It's weird, I set it down I feel fine, but as soon as I start playing with it because I'm bored, these symptoms come back. I think it could be the brightness of my screen and I do wear perscription glasses but only because I can't see far

The symptoms people are discussing don't sound particularly implausible to me. Active Noise Canceling works by destructive interference, usually by sampling input from a microphone and using DSP, which might involve a filterbank or fourier analysis to construct the antiphase signal. These systems are crafted around experimentally-derived models of average human auditory systems. However, there may be some non-zero percentage of people for whom the model might not be a perfect fit, at which point I imagine the results could be unpredictable. If I were to guess, one possibility is something like a low-level intermodulation that may interfere with the normal operation of the vestibular system.

The problem with the display may be related to user reports of some displays having issues with scan lines or interlacing. The flickering may be just on the edge of conscious perception but still enough that problems ensue. That one poster achieved relief with a replacement may support this hypothesis, since not all iPhones have this problem.

Headache and numbness

Yeah, its getting so bad that I'm going back to my iPhone 4S for calls and just using the 5 for LTE data.

Even holding the phone causes pins and needles in whichever hand its in. I had the same experience with the iPad Mini. Not sure the new lighter casing insulates enough.

If I get a brain tumor, I'm going to be annoyed
