Hello,
I have installed firmware v6.50 on my Vivoactive 4 and I'm happy to see that the 0% backlight brightness is back.
I read in another thread that minimal brightness was set to 10% in v6.40, because of a bug that causes unusual battery drain when setting brightness to 0%.
I'm therefore wondering if Garmin devs have only done a rollback of the minimal brightness modification performed on 6.40 or if they have found a way to actually avoid the battery drain when brightness is set at 0% ?
Thanks for your reply, Garmin.
Cordially
Sylvain
