When I'm outdoors, under bright light conditions, then I noticed that when I put my thumb over the light sensor, then the screen colours change and become a bit darker. <STRONG>Note that the adaptive brightness is OFF</STRONG>, and I even tried it when the brightness slider was visible to make sure it doesn't slide automatically. Soooo.... Yeah... For whatever reason, when I cover the sensor with my thumb,&nbsp;then the colours become slightly darker, and it feels like the phone still tries to adjust to the light. When I remove my thumb, then the colours become <SPAN>slightly&nbsp;</SPAN>more vivid.&nbsp;<SPAN>It's hard to notice otherwise, but if you pay the attention then you can see it. It almost feels like it is the colours that adjust and not the brightness itself... <STRONG>Note that this doesn't happen when I am indoors, even during the daytime while in my room.</STRONG></SPAN></P><P>Is this part of Sony's tech, maybe to preserve battery life? Is the phone manually still overrides Android's settings and does it's own adjustments? Whoever has&nbsp;the XZp, try turning off adaptive brightness adjustment (if you have it on usually), go under a bright light, for example under a direct sunlight outside, and try it... Just wondering if it is just my phone or is it every phone...</P> Mon, 21 Aug 2017 16:23:01 GMT https://community.sony.rs/t5/xz-series/xz-premium-light-sensor-and-screen-behaviour/m-p/3562719#M18193 alexGolen 2017-08-21T16:23:01Z https://community.sony.rs/t5/xz-series/xz-premium-light-sensor-and-screen-behaviour/m-p/3562720#M18194 <P>it's a feature called Assertive Display <A href="https://www.qualcomm.com/news/onq/2015/02/20/assertive-display-power-efficient-technology-thats-easy-eyes" target="_blank" rel="nofollow noopener noreferrer">https://www.qualcomm.com/news/onq/2015/02/20/assertive-display-power-efficient-technology-thats-easy-eyes</A></P><P>it changes the display's contrast so that it's more readable in direct sunlight.</P> Mon, 21 Aug 2017 16:25:12 GMT https://community.sony.rs/t5/xz-series/xz-premium-light-sensor-and-screen-behaviour/m-p/3562720#M18194 najodleglejszy 2017-08-21T16:25:12Z https://community.sony.rs/t5/xz-series/xz-premium-light-sensor-and-screen-behaviour/m-p/3562721#M18195 <P>Thank you so much for this information <IMG class="lia-deferred-image lia-image-emoji" src="https://community.sony.rs/html/images/smilies/011.png" alt="Slightly_smiling_Face" title="Slightly_smiling_Face" /> I did not know that!
