Using an HTC One X, first time user. Created a series of points by entering coordinates in WGS (x.x) format. When entering coordinates by hand, I was unable to specify less than 4 digits of precision. Entering 33.790, for example, produced a crash, whereas 33.7900 did not. This was repeatable. Not sure about other entry methods. Specifically reached the screen by going from map to the Data screen, then choosing a category and adding a point.
