Although the problem does not appear to be widespread, several online reports, as well as a discussion thread on Apple’s support site, indicate that some iPhone owners are experiencing what are being referred to as “dead spots” on the device’s touch-screen. An analyst report has claimed that the rights for the iPhone’s touch-screen technology were purchased from a bankrupt Finnish company that was trying to make a similar device. That company is said to have encountered the problem that with extensive use, the screen’s heat-receptive film would begin to degrade and the screen would lose its sensitivity. Apple, while not yet publicly acknowledging the issue, has reportedly been very quick to replace or repair the problem units. If you have any abnormalities with your iPhone’s touch-screen, please let us know in the comments.
