THE PROBLEM:
On my watch, I have the backlight turned off During activity, General Use, and During Sleep. Still, the backlight turns on.
HOW THE PROBLEM APPEARS:
When you start an activity, a forced backlight on the black screen, "wait for GPS," turns on—the backlight then can not be turned off until there is a GPS lock.
Also, whenever you look at the map data screen, the backlight turns on during the activity.
The same behavior also shows when you want to use hotkeys to save a position.
WHEN THE PROBLEM STARTED:
This backlight bug shows after upgrading to software version 13.22 and is 100% reproducible.
The Tactix 7 is otherwise a perfect watch. Thank you for your time.
