I have had the Xperia Z1S for about a week now. And I love it.....but I have an issue with the brightness changing whenever it wants to.
It's not in STAMINA mode. The 'Adapt to lighting conditions' box is off, so I know it's not that. The problem occurs most when I'm playing one certain game - Real Racing 3 - however, it also happens when I open Chrome (rarely), and sometimes when I"m in the Yahoo email app. I can have the brightness set to 100%, and within 30 seconds of opening the apps, it dims to maybe 75%, and a minute later, back up to 100%.
Is there any way to stop this from happening? Is it the game I'm playing itself? I just need to figure it out because it's getting annoying. Any help would be appreciated. Thanks!
