While configuring my new Venu 4 I'm wondering that I can configure a "touchscreen lock" during activity but not a button lock?
Great question! If you want to lock the buttons while recording activities, you can enable that through each individual activity's settings. To do that, select the desired activity profile as if you're about to start an activity > Scroll down to view the activity Settings > Lock Device. You can learn more about available activity settings here.
