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.

Hello,
If I look in the sensors section of "Android System Info", it doesn't list a light sensor (I believe that the light sensor is used to dim the screen when it's dark). The thing is, I've seen the screen dim by itself before. If I put my hand on top of the phone (where the proximity sensor is located... I think...), the screen dims. If I remove my hand, the screen gets brighter.
Does the X10 have a light sensor or not? Is it possible that the light sensor is "hardwired" to the screen without "passing" through the OS to dim the screen?
The light sensor on my X10 is to the left of the earpiece. To the right are the proximity sensor and further right is the notification led.

Since you can disable it in the settings, i don't think it's hardwired.

Good point, I don't understand why android system info cannot see it though. Same goes for the service menu, it seems it's the only sensor in there that cannot be tested.

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

See this [HOWTO] disable ambient light sensor for LCD in xperia mini. It might work on Ray too.

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.
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

I did, it doesnt
First I want to apologise for my bad english. Now, the problem is that the LED indicator on my galaxy is always ON. There is a dim red constant light. The phone isn't charging or having low battery. Even when the phone is switched off the light is still there. It shuts down only when the battery is unplugged. All other notification lights are working well even when plugged in charging the red light is brighter. I'm using Stock 4.3 Jelly Bean and I'll attach a picture if you didn't understand what I was explaining. Thanks !
That's the proximity sensor not LED... It must be in active mode constantly due to some app you have installed.. So just look fit any app that might have permissions for your sensor....

No it's not the proximity sensor. I made the picture with a mirror because I didn't have another phone or a camera in hand. The problem is with the led light which is on the left side of the earpiece.

Hello from Indonesia. I'm user of Xperia X single SIM which use the newest version of Poison ROM based Nougat 7.1.1. I have a little problem like this thread https://talk.sonymobile.com/t5/Xper...sor-when-3g-4g-data-transmission/td-p/1146470 but the difference is the red light in my phone always ON both when data transmission/WiFI ON and OFF. The red light OFF when I locked this phone, and when I unlock this phone using fingerprint or press power button, suddenly the red light ON. I have the adaptive brightness screen turned off before. Anyone can fix this problem? Thank you so much for your help. Sorry for my bad English.
Turn off the auto brightness option
Turning off adaptive brightness is not working and it looks more like a feature than bug. (Proximity sensor gets active on lock screen or after data/wifi use to detect if flip cover is covering the screen or not?)
