Help Screen issue

[rborans]

I just purchased the Nexus 7 and noticed when using it in my car the screen darkens when turned horizontally. This is a bit annoying since the dashboard mount I have for it sits that way. This doesn't occur at any other time except in my car. The only factor I can see that is different is that I have an audio cable attached for sound through my speakers but it still shows the screen fine when held vertically. ???

is maybe auto brightness kicking in? does it happen at night or in the day? or both?

 

[rborans]

So far I've only tried it during the day. What does the auto brightness option do?

 

[h4x0rj3ff]

depending on how bright or how dark it is your tablets screen will darken or lighten to combat this go into settings (if this is your problem) and under display click on brightness and uncheck auto brightness

 

[rborans]

Auto brightness is already switched to off. Also, the darkening only occurs when the tablet is in the horizontal position.

and its not rooted? are you playing music thru Google music or a different app?

 

[rborans]

Playing through Google but it also occurred when I was using the navigation program.

does it happen while using any other apps? or just Google music and Google maps? im trying to replicate it on my device but im having a hard time

ok in navigation go to menu (upper right hand corner three dots) and lick on settings. theres an option to dim the screen to conserve your battery!

Thanks, I found that and unchecked it but I still don't understand why it is happening when I only have music playing and only in the horizontal position. I haven't tried it using any other apps.

Just a random thought, sorry. Are you wearing polarized glasses in the car during the day? My dark glasses make the screen look darker in horizontal than portrait due to the polarizing effect.

Groid, You hit it! I realized just a few hours ago that my prescription sunglasses react with the screen when turned horizontally to make the screen look black. Very strange.
