I sweat a lot - like a steady shower. I lock the screen, but it isn't truly locked. My sweat pours on the screen and it constantly changes the metrics I have chosen. And worse, it even causes fields to be swapped around from their physical location. And since there is standing water and constant drops of sweat falling on it, it doesn't pickup the fact that my finger is touching it as I try to reset things.
When I lock the screen I want touch disabled!
Another related pain is that my headlight constantly connects and disconnects from the light network. Each time causes a message to cover the bottom of the screen. It doesn't go away until I tap it which means I have to unlock the screen and tap the message to make it go away. Reread my first paragraph to see what a pain that is for me.
Just finished a ride with it in my back pocket. Not useful at all in my back pocket.
Lock may work for non heavy sweaters, but I need a complete disable of the touch screen until I hit a physical button.
For me, this is a piece of useless weight I'm carrying.
