If touch is working, digitizer is good. If not, it's broken. As far as I know, there are basically three layers in Samsung phones, (I think it will be the same for others)
1. Protective glass (as its name protective)
2. Digitizer ( detect touch)
3. Amoled display (produce color)
Hit thanks if this help you
