So far my new zenwatch has been great. However, I have noticed in a couple apps such as Multi Calculator for wear, that buttons at the bottom like . and at the top like ac/c don't respond very well. Then I noticed that throughout the entire watch interface, the top and bottom 1/4 of the screen (not the bezel) are entirely unresponsive to touch. I wanted to see if this was a defect or possibly a byproduct of that curved glass not allowing the capacitive sensor to extend beyond that middle portion of the screen. Does anyone else notice this?
