Touchscreen help for Irolo Mid google tablet

To be exact my item is the Irola Mid Google Android 4.2 Dual Core 1.2ghz 8gb. Is there a way to make the touch screen more sensitive?? You have to press or swipe very hard to get it to work, and the stylus is no better. I saw something that said go into the settings and select to calibrate it, but there's no option for it there?? Even though the owner's manual say's it is?? This was a gift for my son and he's already disappointed with it.
