As stated, I don't even have the "adjust to lighting conditions" box checked, so that shouldn't matter.</P> Sat, 08 Feb 2014 08:56:22 GMT kcnjojo 2014-02-08T08:56:22Z https://community.sony.si/t5/xperia-archive/xperia-z1s-brightness-changing/m-p/3163635#M334348 <P>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.&nbsp;</P><P>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%.</P><P>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!</P> Fri, 31 Jan 2014 17:10:34 GMT https://community.sony.si/t5/xperia-archive/xperia-z1s-brightness-changing/m-p/3163635#M334348 kcnjojo 2014-01-31T17:10:34Z https://community.sony.si/t5/xperia-archive/xperia-z1s-brightness-changing/m-p/3163636#M334349 <P>Do you have anything near the proximity sensor?&nbsp;</P> Fri, 31 Jan 2014 17:23:36 GMT https://community.sony.si/t5/xperia-archive/xperia-z1s-brightness-changing/m-p/3163636#M334349 Uliwooly 2014-01-31T17:23:36Z https://community.sony.si/t5/xperia-archive/xperia-z1s-brightness-changing/m-p/3163637#M334350 <P>No. I don't.
