Details

While the backlight is on, all touchpad functionality appears to function normally. I have used a number of daily builds, the current one I'm using is d2f97da-120216. I am running V7 of the bootloader. I reset my settings to default as well.

With "First press turns backlight on" set to "no" and the backlight currently off (keyclick set to "weak" and no repeat):

Menus -
tapping right acts as if I'm holding on the center
tapping left, up, down, or back acts as if I tapped the respective spot twice (goes up/down/back two menu items)

WPS -
tapping right or left acts as if I pressed and held to start to skip through the track (two audible clicks and the Play icon changes to the FFWD or Rewind icon temporarily)
tapping play/pause while music is playing will pause the music and go back one screen
tapping play/pause while music is paused will simply go back one screen

With "First press turns backlight on" set to yes and the backlight currently off (keyclick set to weak and no repeat):

Menus -
tapping right acts as expected (turns backlight on)
tapping left, up, down, or back acts as if I tapped the respective spot once (goes up/down/back one menu item)

WPS -
tapping right or left acts as if I pressed and held to start to skip through the track (one audible click and the Play icon changes to the FFWD or Rewind icon temporarily)
tapping play/pause while music is playing will pause the music and go back one screen
tapping play/pause while music is paused will simply go back one screen
This task depends upon

I confirm this: the touchpad is definitly doing strange things while backlight is off. Whe should test this on other target to know if this is fuze+ specific

I can confirm this on my device. It doesn't seem to be fuze+ specific but needs some investigation.

I have fuze v2 (latest official build and several versions prior) and a new fuze+ (latest daily), and confirm that this is an issue with the fuze+ which i've never observed in the fuze v2.
