[Q] CM7 -> light sensor not working - Legend Q&A, Help & Troubleshooting

Hi,
my light sensor value is always at 33,no matter what ambient light there's in the room.
I'm using CM7 stable.
Any ideas?

and you see it in what software?
try to bring it exactly under desk lamp, if you use Elixir.
There is some "low" dead zones, need high contrast to see changes.
If not then wipe reinstall.

Hi,
i've checked with cyanogens build in feature.
Then i've installed elixir,placed the device under a lamp and the sensor started working and is working eversince.
So thanks a lot,"problem" solved.

[Q] Atrix Proximity / Light Sensor

Hello guys,
My proximity / light sensor is not behaving correctly for past few days. Now whenever i dial a call, the proximity sensor turns the LCD off and it does not turn it on until the call ends somehow. It seems to be that the sensor is unable to sense the incoming light. Also the little red LED of the sensor stays on for very long, even after the call.
Also, the screen's brightness does not change when i move from low light to high light areas (and vice versa).
I have jokersax's CM9 build 0.6.1 installed with the built in kernel. (Which is probably the CM9 kernel too).
I suspect the proximity sensor is faulty. And also that this is a hardware problem. Now the question I'd like to ask is does anyone know what parts do i need to replace in order to get it back working. What would I tell the repair part vendors to send me ?
Also, do you agree that this is a hardware problem??
OR do you think, it is the ROM may be or the way I've installed it??

If you have face unlock enabled then disable it and try it again.

light sensor

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.

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.

[Q] Auto brightness not working

Hi!
I have the S6 edge since yesterday and I noticed that auto brightness does not work.
Testing the senosr via a sensor read out tool, it actually detects brightnes levels well (as far as I can tell).
However, if I turn on my phone, it is first super dim at first. When I expose it to a flash light, the screen turns brighter and eventually maxes out. But it does not turn back to normal brightness levels once I remove the light source. Sure I can adjust auto brightness with the slider. But it is then much brighter (with same light conditions in the room) as when I truned on the phone...
Only if I turn off auto brightness, the screen reverts to the setting I have chosen...
If I turn auto brightness on again, it is as bright as with flash light exposure...
What is going on here?
Does anyone have an idea how to fix this?

I have the same problem. Already talked with Samsung and ATT. They want me to change the phone.
Ps. It seems the problem only persists in S6 edge not in S6. But I also found that other android that run lolipop 5.01+ have the same issue too. And right now, I use the app name velis auto brightness to fix this.
I will try to change the phone by this week and update you.
Hope this help.
I have started using an app called Lux. And it has no problem adjusting the brightness. The sensor clearly works fine as it can always displays the brightness detected by the sensor. So it has to be a software problem.
I could imagine that a hard reset could fix the issue. But right now, I do not want to go to the hassle to restore everything
Let me know how the new phone works. :highfive:

The hard reset did not work, I already did it.
I will update you again once I change or test the other phones.
I went to the store, and both S6 and S6 edge in the store all have the same problem, so the exchange it may not solve the problem.
I think this problem may be a software problem or an intention from Samsung/Google.
I will try to use it in couple days. If I cannot bear this, I might return the product.
Hope they will have OTA update soon.
Got this too.
It's really anoying.
I really hope there will come an app like on older Sammy's that we can set and adjust our own brightness levels.
But I'm not expecting a fix from Samsung tho. They have proven again and again they are unable to fix their crappy software. Especialy if it's a minor bug like this.
So anyone wanna buy a rooted hardly used S6 Edge plus?

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?

me too,but i've noticed that only blinks when its recieveing data when changing from wifi to 4g and viceversa,when its done,it doesnt blink anymore.
Does anyone have any idea for this problem please ? :'(

@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.

Sensors not working after replacing the battery

Hi,
after replacing the battery of my SGS6 Edge some sensors are not working.
1. Light sensor is not working when the brightness is set to automatic
2. Gyroscope sensor is not working when screen rotates
maybe other sensors are not working properly too.
I already tried to restart the phone but there is no effect.
On the hidden service menu the the light all sensors seems to work.
The light sensor is working 100% - when I cover it, it shows "0 lux"
The Gyroscope Sensor is working too, but what does the "OIS GYRO" mean? The value on X and Y does not change.
It's my business phone with a lot of data and apps. Thats the reason why I still don't try a hard reset.
Is there a solution whithout resetting the phone?
EDIT: Gyroscope seems to work... strange. But light sensor is still not working. Brightness does not change.
i've similar issue with mine, but I don't know if battery was changed before was given to me, I tried many roms nougat and marshmallow based, but the problem persist. with automatic brightness on, if I scroll the bar, it doesn't change anithing, I've to disable the automatism
