I just received a Venu 4, and spent some time trying to find the option to turn off adaptive brightness (which I find very annoying) but couldn't find one. I thought my watch had a problem, until I did some research and found out that there is no way to turn that off. I've never seen any modern device lack the ability to turn this off. Please Garmin, add this feature. I want the same brightness no matter the ambient light, and with the Venu 4, adaptive brightness does not work well, as the screen gets way too dark to the point that I cannot easily read the screen. Honestly I have yet to see a manufacturer implement this well, and prefer to turn it off completely in all devices I use.
Thank you
