mouse doesn't have an angle-snapping behavior. To put it in a general statement, the G400s Optical Gaming Mouse model is basically designed without the angle-snapping behavior.
The conditions of having to know the PID code of the mouse first only applies to some specific batches of the Optical Gaming Mouse G400 (please refer to this post thread). BTW, I've sent you a PM with regards to this one. Please check your Inbox.
Although there are some Logitech G-Series gaming mice that has an option to enable or disable angle-snapping feature in LGS (like my Gaming Mouse G500, which I prefer not to enable), this behavior was completely removed even in the LGS settings of the G400s mouse.
