I think my optical track pad is not calibrated. Sometimes (often) when I unlock my phone, the screens start automatically shifting to the right. If I manage to open an app, the selection keeps going to the right. For example, if I am in a text message and am trying to move the cursor to a previous work to correct spelling, the cursor keeps moving the right and down on its own. Is there a way to calibrate the optical trackpad? Anyone else having this issue?
