Hi. I have the same problem,i think this has nothing to do with adaptive brightness. i tested it so many times and it happens only when mobile data is on. when making a call it's normal thing blinking that sensor.but with mobile data it's strange.idk but i feel like battery draining fast too.here is little video about it - https://www.youtube.com/watch?v=UZFsB9b5p6g my device is xperia x dual F5122 , software 34.0.A.2.292 is there any solution? i also repaired software. will this go away with android 7 nougat? or i have nothing to worry about.but im a little concerned. thank you!
