One of the first things consumers may notice after purchasing an iTouch is that you cannot calibrate the touch screen. Since many touchscreen-based devices make you calibrate the screen right away, this may come as a shock to new iTouch owners. The touch screen comes pre-calibrated. For most people, this is enough to use the touch screen and interact with the device without issues. However, for others, it may pose a problem if the iTouch does not work the way a consumer wants it to when they are using it.
If your iTouch screen is giving you issues, there are two ways to troubleshoot. The first is an overlooked method that many touch screen users, in general, fail to think about. You want to clean your touch screen. Take a small cloth and spray a little glass cleaner on it. Do not over-saturate the cloth. Wipe down the touch screen very thoroughly. You may not realize just how much dirt, dust, fingerprints and grime have built up on the screen. Try using your iTouch after cleaning it and see if it responds better.
If it does not, you want to try restarting the iTouch. Hold the top button, along with the “Home” button down for a couple of seconds. It will prompt you to use a slider to shut down the iTouch. After a few minutes, you can turn it back on and see how it responds now. For the most part, these are the two ways to “calibrate” your touch screen on the device. While they are not the most effective ways to get the most out of the iTouch, they are your own two ways to combat issues you may be having without returning the handheld device to a retailer or looking to get it repaired or replaced.
