The the bottom NDSL screens are actually 2 screens on top of each other, there is the NDSL bottom (image) screen which is responsible for the image you see, and there is an NDSL touch screen overlying the image screen which is responsible for the touch sensitivity. If you are purchasing this item be sure it is the NDSL touch screen you need, and not the NDSL bottom (image) screen. See below for further guidance. Also please note that is it helpful to recalibrate your NDSL touch screen after replacing it to maximize the touch sensitivity accuracy.
