iPhone touch screen and static interference

February 6, 2009

Recently the touch screen on my iPhone has been behaving quite strangely. Every so often it’ll either stop reacting at all, or will behave as though I were jabbing my finger all over it in random places. The latter is quite annoying as it’ll often end up sending an email or calling a random contact out of the address book.

It seems to be caused by static electricity building up. If I touch a grounded metal object while holding the iPhone, the problem stops. At least for some time, then eventually starts again.

I’ve taken it back to the shop a couple of times, but they’re not convinced that it’s a problem with the hardware. Their idea of fixing it was to spray it with compressed air, and then do a complete reset of the software. Neither are practical solutions, really. They say they won’t replace the phone unless the problem can be reproduced in the store, immediately after the SW reset. And of course, it doesn’t happen then…
