Hello, I just updated my mini to the latest 4.0.A.2.377 firmware, and now each time I wake it up from locked the screen is flickering a little, really annoying..
Anyone else has the same problem?
Update:
The screen doesn't flicker at all when connected to a charger. Obviously then this must be a software problem and not hardware. Does anyone have any thoughts or experiences?

Yes same here. But it so happens when I'm in a low-light environment.
This is normal I guess

No it's not normal. It wasn't like this before, it started after I updated..
It doesn't bother me at all, that's why I never noticed it before I've updated it.

I try Z DeviceTest an the app say there was no lightsensor. Its thats the reason for flickering? No driver for the lightsensor or anything else?

What's the problem??
I noticed the flickering when I set the display brightness to a low level (<50%) and whenever the screen adjusts to the background light so it seems to be caused by the light sensor...
Yeah but my screen also flickers when the phone is locked and turned off and you press home button to wake it and the first second its awake the screen goes from full brightness to non and back to full again. This wasn't there before :/

The brightness of the screen is very normal, and the absence of an ambient light sensor is a disappointment – the brightness requires a manual adjustment every time you go out.

Taken from here
And also SE support center confirmed that it does not have a Ambient Light Sensor.
Then it would seem very stupid to have autobrightness as default and no option to turn it off if the phone doesn't have a light sensor.. Hope they add that option in a future update!

Use power widget and turn off auto brightness. It will not flicker a lot like before. I used this on my mini.

According to SE support, this is a common problem unfortunately..

Tried that, no dice. I only really see the flicker on a full white screen.

It does have a light sensor. I just read the manual and it says so.
Page 14
"Your phone includes a light sensor and a proximity sensor. The light sensor detects the ambient light level and adjusts the brightness of the screen accordingly."

According to a couple different sensor detecting programs, there is no light sensor. Maybe the sensor is defective?

This is normal. To people who got annoyed by this it's your problem not SE

What is people smoking?
Of course there's a light sensor, why else would the screen dim up/down at all?!
As for the app not seeing the sensor, my guess would be that the sensor's just made differently or actually being in direct circuitry with the screen/backlight, and the two are recognized as one.
I haven't heard anything on the subject, but i would imagine that it's fixed in the next update (2.3.4).
Any fix for this?

I found that Xperia Ray have Ambient light sensor from the white paper, but i can't use it on stock roms or CM7, can someone enable this?
this is the link of white paper
http://dl-www.sonyericsson.com/cws/download/1/997/193/1308295710/ray_WP_1.pdf
thanks!
Good question!
I also found in the whitepapers that the Xperia mini pro (sk71i) has the same ambient light sensor but when I check with android tools like "Sensor List" the only thing that could match is the Proximity sensor. That one goes from 1 to 0 if you get close to the top (blocking the light?).
APDS9702 Proximity
The sensor is enabled by default
how? i can't feel that
With my HTC Desire Z I had the "auto brightness" option. On this one I don't. Are you sure it is enabled? Do you have any clue what sensor it would be in the list of for example android app "sensors list".

As of Stock Rom 2.3.3 and 2.3.4 there is no 'auto brightness' option.
But the ambient light sensor is always working.
If you take it outside in bright sunlight, you will notice that the screen automatically gets brighter. That's how you can tell the sensor is always on
I assume they haven't put auto brightness in as a feature because maybe some people want to save battery/adjust their screen brightness for indoor use.
But when the surrounding light passes some threshold (ie, outside), the auto brightness feature overrides your user settings...
thanks.....so, can i make a option for this?

No, there's no select-able option for it. It's always on.
check "brightness level" widget in android market. I just added to my desktop and it has an autolevel option. Seems to work. But I can't say if it's really off when you select only a percentage.
LOL! Check some of the newer topics. Many users want to disable the auto brightness. The topics have some info for rooted users. But as said it seems to be enabled by default.
It's not linked to the 2.3.3 update though. My desire Z also had that Android version and still provided the auto brightness option in the display menu.
It also seems to be the reason of the flickering screen on low backlight setting. That is in fact annoying.
So, how can i disable the sensor? I want my screen always to be bright, i hate this auto adjusting

Thanks. I wanna keep my warranty though
If there is a light sensor on my ray then it must be disabled.
Mine does not react to any changes in light at all - even if I manually cover the whole of the top of my phone in my fist.
I also find that the screen is odd outside in the sun. It looks exactly the same if it's set to 25% brightness or 100% brightness (both are just as easy to see). I can only notice a difference in brightness when i'm indoors or if it's dull and cloudy.
FYI i'm on 4.0.A.2.368 - 2.3.3

Screen Auto Brightness is not working on my Xperia Ray too.. I don't know why this feature was disabled... I tested light sensor and that works but brightness never changes... Is it because of old 2.3.3 firmware i have ? I didn't update to latest yet..
I don't know if it's just me but sometimes my screen kind of flickering.
Is it true that it's because of the light sensor just too sensitive?

For me,Xperia Ray owner are very lucky.
Because the light sensor is implemented very bad on Xperia Mini for example.
The screen flickering and your eyes cry. : (

Yes,is a very boring problem.
The Xperia Mini has two big problem.
-Touchscreen lag
-Flickering screen
Check out this post on the Xperia Arc - works great just the same for the Xperia Ray. Also the linked program well depicts the relation ambient light value, brightness setting and the resulting screen brightness.

hi all, I noticed that light sensor doesnt work properly, when I go from dark to light area, the brightness increases but when I go from light to dark area the brightness wont decrease, on honeycomb it worked properly, anybody else experiences this problem?
Same here, it goes bright but does not decrease.
I use the app https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&feature=search_result#?t=W251bGwsMSwxLDEsInJ1YmJlcmJpZ3BlcHBlci5EaXNwbGF5QnJpZ2h0bmVzcyJd
make an invisible slider on the edge of screen to adjust brightness.
is there any way to make it work properly?
Don't think so. Its pretty much unusable now.

There are lots of negative comments about light sensor, but i have to say it works well to me on ICS. Could be possibly massive amount of defected devices.
Lightsensor doesn't work for me either - too bad, hope it will be corrected.
Perhaps it's because I'm running ICS "General Channel".

Do the sensor dim the light in the same session for you?
Here it turns up the light but not down again.
Sent from my U8800 using Tapatalk 2
Same here, adjusting upwards works fine, but it doesn't adjust downwards in low light conditions.
I have tried two apps that turns the light down again, custom auto brightness and lux auto brightness.
One small problem. The pad will crash on pattern unlock after sleep. I Also the light sensor will not work s after wake up sometimes.

I'm guessing no one has had any luck with this issue but I figure I'd necro the thread anyways. My light sensor sucks also. I used 'Android Sensor Box' to get the values coming out of the sensor. It only displays either 40 lux or 280 lux which is obviously not right. This is on Cyanogen 9, stock t-mobile ICS and the rooted international gingerbread(can't remember which one exactly).
So I was wondering if anyone who owns one of these has ever gotten a sensor value that makes any sense.
thanks
nope,
I use instead display brightness https://play.google.com/store/apps/details?id=rubberbigpepper.DisplayBrightness&hl=no
create an invisible brightness slider on theedge of the screen.
Try using custom auto brightness with the auto brightness on (there's a setting in that app that disabled the system auto brightness at screen on. Turn it off).
The original kernel only recognized 3 light levels. If you use bart's kernel it will recognize 6 levels.
Yes, I think there's a software problem because both app (lux and cua) crash hard in HMP, but I don't think fixing it is a priority.

How to use custom auto brightness without crashing the tablet.
There are 2 options that should be followed, other settings can be adjusted to your liking.
1. In preferences, Check Use pulsed sensor mode. Basically this option will make the app read the sensor itself instead of listening the sensor value given from the system.
2. In advanced preferences, set the sensor update speed to either half sec or 1 sec. I tried normal, but the app won't read the sensor value, so probably the slow normal maximum setting only works if you get the sensor value from the system.
You can set disable system auto brightness. I recommend it before because the setting was a "hack" which was making the system read the brightness value thus the app can get that value. Right now it's recommended that you check the disable system auto brightness.
can anyone tell me what the duck is that thing installed in my mini pro that is supposed to be a light sensor? it does control the brightness level depending on ambient light, but it doesn't work with apps that allow you to change brightness according to your own rules. I've tried Lux Auto Brightness and it acts as if the phone didn't have any light sensor, but when I go to service menu and test the sensor, it does react. so what's going on there?
Sloppy implementation, I guess.
Why are you trying to use third-party software for it?
Most of 3rd party test service shows LIGHT SENSOR,the mini pro have AMBIENT LIGHT SENSOR.Both act same,but different driver and name

I have a feeling that Lux does better job (even though I set it to measure light via front cam).

Hi.
Could it be that auto brightness feature isn't working properly on XU?
I have a feeling display always has same brightness regardless light or daylight or night.
Is there a way to test the sensor?
Thx
Yep, put your brightennes to 50% and then light your sensor with sone light or lighter close enought, sensor from your left side of speaker.
P.S as far as i noticed on this xperia sensor work only to get your screen more brightennes and not to reduce it

Sent from my ST25i using xda app-developers app
Autobrightness works fine, Sony just implements it differently. Choose a brightness level, now this brightness is going to be the minimum the screen will go to. If you go outside or are in a room with bright light it will adjust by raising the level but never go below the minimum you have set. The autobrightness is actually really good the way it works, i have great sun legibility. Hope this helps you.
But why apps like sensor test say there us no light sensor?
maybe new sensor ....
How many apps have you tried?
