light sensor meter - Sony Ericsson Xperia Mini, Mini Pro, Xperia Pro, A

I have tried many apps showing sensors and light meters but none of them found the light meter sensor.
When I went to service mode (by dialing *#*#7378423#*#*) I saw the values of the light sensor working well and monitor illuminance works great as well.
Why sensor apps don't show the light sensor? Does anyone else has the same problem?

It's because the sensors are a new type from Sony Ericsson and the apps doesn't recognize them.

[Q] Flickering screen each time screen is turned on.

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?

[Q][U] Auto Brightness

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

AndroSensor app says the phone did not have a light sensor??
You its working I tried a sensor control aplication(i dont rember the app name but it is controledy phone when I moved my hand upper the sensor)
Sent from my ST25i using xda app-developers app
The sensor works, the autobrightness no
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?
Androsensor and Sensor test.
The dial *#*#7... Dont have number in mind says sensor is working
Im on KA03

[Q] Xperia Active questions

So I've used the search bar and google
there are 4 circles at top
1. Ambient Light sensor
2. LED notification lights
3. ???
4. Proximity Sensor
so whats in between the earpiece and proximity sensor
also why dont apps recognize the ALS? I've used android sensor box, androsensors and my android sensors but still nothing. Though auto brightness works. I know, I move my finger over it and the screen gets dim

The last 2 sensors are for proximity i guess, cause even on my mini pro i have 2 circles for proximity. In the stock rom, it is never detected, its on by default. In roms like cm10, CM10.1 etc. you can choose whether to use it or not, change the different levels etc.
Well in mini pro its
Led, ambient sensor, camera, proximity.
Tbh, I think I have seen two dots instead of one for sensor. (Really hard to see)

Yep there are two sensors for proximity.
why are there 2 sensors for proximity? using the sensor apps I've noticed that only that the right most works the 3rd one doesnt really do anything when i cover it. but it works so I'm fine with that
but how come the apps dont detect the ambient light sensor? that too is obviously working because the screen dims when i hover over it
Try using the service menu and see if it works there

[Q] if you don't have the proximity sensor problem, can you try test?

I'm trying to figure out normal (functional) proximity sensor response to light.
(originally posted this to meanbean because I downloaded meanbean specifically because it mentions the proximity fix.
Would somebody who doesn't have a problem with their proximity sensor try the following:
1) Use whatever program you like that displays current proximity distance. I've been using Proximity Sensor Finder.
2) Confirm that near and far are reporting correctly (it's binary, but reports as 9cm versus 0cm).
3) Expose the phone to strong light (e.g. put it near a light bulb).
4) Remove from light source
--> Does the proximity sensor now report NEAR even when there's no object near the sensor?
I really appreciate your testing this and letting me know here or by DM.
Thanks so much!
Have you tried this:

Proximity sensor issue

Hello,
Has anyone noticed a promixity (maybe ambient light) sensor issue? Often (more in the dark) I can see a weak red light blinking right where there is the proximity sensor(it stays there if automatic brightness is on). I tried disabling and closing one app per time but it seems more like a software bug...
Anyone else?
Sony Xperia X F5121
Hello ! Yes! (sorry for my language I'm French).
Tonight, after charging my phone at 100%, I have seen a red little light in the '' capter '' a the right (for automatic luminosity I think). It was a big bug who during ~ 30 minutes. And I have lost 20% of battery, I think, cause to this bug.. Do you already have the bug today?

@Mr High Tech @kistigun @kalel29
Are you kidding me guys? :laugh::laugh:
It's not a red light.... It's barely visible because it's an Infrared Sensor Infrared light is usually visible only in very dark conditions.
Hint that will make your day - when it's dark and you barely see it, try pointing a camera at it! It flashes white now, doesn't it.

more than wanting to know what it is, i think they want to understand why; why does the proximity sensor stay on?
i had this question too, before updating to the latest firmware (.292). after that, it seems the "problem" doesn't occur anymore, but i'm not that sure. i'll have to double check.
however, do some of you use "Smart backlight control" feature?

Smart backlight control makes use of the accelerometer of the phone. Keeps the screen on by detecting movement. Neat feature.
Smart call handling on the other hand uses the proximity sensor. Also the style cover preinstalled software. And of course Call handling uses the proximity sensor.
I'm using a modified version of Gravity Screen for pocket mode. Proximity sensor flashes all the time in order to turn the screen on and off when it's in or out of the pocket. Also I use the proximity sensor so that the screen won't turn on when it's in the pocket - like when a call comes in and I don't want to accidentally answer.
One thing you should know about the proximity sensor is that it uses a crazy low amount of power (0.18mA). Now the software that uses the sensor might have many wakelocks but we also need features so it's a small price to pay haha. Also if you're planing on using gravity screen (which is a cool app), you can always add a on/off widget.
There's really nothing to worry about - none of those features/apps I mentioned register on power consumption.
