I recently have moved to Ireland to study abroad for 6 months from the US and I have had major problems with the touch screen of my iPhone 4s. It will randomly lose the ability to click what I am intending to touch. It instead will hit several buttons at once, click higher or lower, or not even respond. I was given several suggestions such as 1) the calibration is off 2) Ireland has a lot of moisture in the air which is throwing it off. This is actually happening to my Kindle Fire as well. Any suggestions?
