Hi all. I found a very weird and specific problem on my SP3. Using a PIN login, "1" on the keypad only works around 50% of the time. I thought I had a deadzone on my touchscreen so I rotated my SP3 around to realize that "1" is unresponsive on all four sides. There is no deadzone in the area where the "1" on the keypad is when I login. Does anyone else have this problem?
