My iPod Touch is not responding well to touches.

The most common cause for touch response problems with the iPod touch is using a non-Apple brand USB power adapter or lightning cable.

Next, try resetting your iPod. Start the settings app and then choose General/Reset/Reset All Settings. This will not affect your recordings.

If that doesn't work, try removing the case and see if the iPod responds better. If it works better, clean the iPod and case, this might fix it.
