Why is my finger not working on my touch screen but the s-pen is?

[AC Question]

I have cleared my cached partition, factory reset and everything else including firmware updates and it just won't work.

Could it simply have failed?

Probably hardware problem. The Spen uses different sensors to the one used for touches and regular stylus.
