Xperia Arc automatic light sensor

Sun, 22 May 2011 15:48:12 GMT

Hi there,

On my Xperia Arc when I go on display settings there is an option to change how bright the screen is, however there is no option to make the light sensor automatically change the brightness.

Does anyone know how to set this?

I checked every possible settings and options and cant find it anywhere

When I had a Xperia X1 there was an option for this and worked really well.

Thanks!

I'm sorry but there's unfortunately no option for this in the phone, but if you set the brightness to 100% the automatic sensor will be deactivated.

I've forwarded some feedback on this to concerned team.

But isn't it his question if there is an auto brightness setting (yes there is)? Or have I misinterpreted the question?

yes there is, just add the widget to the homescreen

press MENU -> add -> widgets -> powercontrol or on/off backlight

tap the icon until the phone gets dark then tap it again, that will turn on the light sensor, if you tap it again it will maximize the brightness, tap it again and the backlight will be off, and so on

Hello,

Yes your right!!

the only way to set the automatic sensor is if you add the power control widget, seems weird its not on the display settings page. Thanks for your help!!

I followed your instructions, but it didn't work. My Android is on 2.3.3 version. Could this be the problem?

I hope that SE fix this or I will have an useless sensor.

You can try going to Service Menu

This is how you enter Service Menu on the Arc, Neo, Play, etc

Open the Dialer and press this

*#*#7378423#*#*

Go to Service Test -> Ambient Light Sensor and Proximity swith

test them

I tested both and the Ambient Light Sensor is working fine but the Proximity Switch is set OFF.

Is it the problem? I don't know how to turn it on.

The proximity switch worked as you said, but still the automatic light sensor is not working.

I think the ambient light its working but its not as sensitive or it doesn't change the brightness of the screen as fast as other phones

This may look like it, but when I bought the Arc the sensor were working perfectly and the response time were very fast.

Now when I'm using the phone in the dark the screen gets too bright and I have to adjust it manually.

Isn't this a bug that should be fixed by SE? Or is ir related to Android?

I think its a SE issue, I agree even if its dark the screen remains bright atleast at 80% brightness

I use the power control widget and the Quick Settings widget, I hope this issue gets addressed w/ the next update

I think I will have to wait a bit to see my light sensor again.

Anyway thank you uliwooly for your time!

This discussion really helped me to fix my XPERIA Arc's light sensor so I decided to give more clarity for those who need a step-by-step guide.

My phone runs Android v.2.3.3 with Sony Ericsson's build number 3.0.1.A.0.145. It is in a state of newly received device without any softwere updates.

1. There was an On/Off: Backlight widget already on the desktop in my phone. It does not switch to an automatic backlight scheme. The only possible states are Min backlight and Max backlight.

2. Another widget called Power Control I added from the widget menu. It has three states, Min, Auto and Max backlight. Auto and Max share the same icon so you won't see which state is switched on.

3. To see the difference you have to adjust the brightness in Settings -> Display -> Brightness to a lower value. Then, if you are not on the bright sun, you will see the difference in brightness.

4. In Auto mode brightness change is not fast (in my device it's approx. 1 point per second) so you may just not notce it's working. The best way to check is to put the phone in a dark place and use a flashlight.
