I've noticed every since the beta program for Nougat for the Nexus 6p that at a certain time during the day, no matter what automatic brightness setting you have your display set to, the screen will unfortunately automatically dim . I understand in the Nougat version on the Pixel that there's a nightlight mode but this isn't it. It's literally dimming the screen usually to almost unusable brightness levels. I've tried to adjust the brightness slider to half way, however unfortunately that doesn't seem to make the screen brighter at all. I've even tried t to pretty much "Max out" the brightness slider, however that will just burn out the battery excessively of course. My workaround for now has been to just go into the phones brightness settings and turn off automatic brightness mode and keep the slider at a very minimal level. I think it's got something t do to with the light sensor on the phone in conjunction with the beta software. Has anyone else experienced this at all? Thank you for any feedback!
