[Q]Working Light Sensor - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

why every build claims to have light sensor works while it doesn't. I tried every build that says light sensor works. Well, that works only If I open an app call "Android Sensor Data", then I can see the light lux changes as well as the screen brightness, once close the app, the system just wont update the light sensor......
can anyone confirmed that it's actually working? like put the phone under a lamp and the screen will have full brightness?

No, it doesn't work properly... WiFi, data, G-sensor, battery, camera aren't good also. Bad luck...

why every chef says it's working then? Really confused, I tried at least 4 builds tonight, frustrating.....

it does work, but not properly. U need to enable "Automatically Blacklight Adjustment" under WinMo before boot into Android. Light Sensor works on fresh reboot, but after using android for awhile, and light sensor not working anymore. To get Light Sensor works again, u need to fresh reboot android again

thanks, will try. I am using chucky droidrom and can't find auto brightness option.

Lets just be thankful that we got android running on our phone...if you must have auto light, use winmo...

Thank u so much. I finally managed to find the registry key that controls auto brightness in chuckydroidrom, and now auto brightness in android works (for now)
BTW, I am thankful to the developers, however, thought they should clear things out instead of just saying "it works" and omit the part "how".
I googled all night, read carefully every 1st post in every build, couldnot find anything related, that's why I asked
Thanks again to every contributor

I open phm registry editor in winmo(included in "tools"), search "backlight" in the current user section, u will find "backlight" under "control panel", there are several keys in it. change "lightDetectOn" to 1 and the screen brightness will change immediately according to ambient light.
launch android
PS. after some time, auto backlight stops working..... and I think the sensors still works coz when I open android sensor data, it reads normally, the system just ignore it after a while.

Thanks for the enlightment. How about in the Android,do you change any settings?

didn't change anything, just enable auto brightness.

Disable light sensor

Hi guys. Now, when we have root for 2.1, is there any chances for disable light sensor?

Good point. That or ..
Original Eclair dialer would make this phone much better..
Would be great to disable this damn light sensor. I don't understand why can't we disable it to the hell out??
The light sensor seams to be OAM apk, so maybe removing them would disable light sensor... I didn't try yet, so if someone try, let us know if it works.
Where is it?
I did a misstake : it's not OAM but OMA.
And i think to remember that there were 2 OMA apk in system/app folder
i have install "quick settings" and there is an option to turn on/off light sensor
I installed it but I don't manage to find the option

Disable Light Sensor
I made it. now here the instruction:
1- download attach
2 - unpack it
3 - copy to the phone /etc/
4 - chmod 777
5 - reboot the phone
Thats all, you don't see work of this sensor.
Ok, it works at 100%. But... Ekhm... brightness is just crazy now xd I think I prefered old settings ;p. I'll try it tommorow.

This doesn't work for me... I have 2.1-update1, latest pre-rooted Chinese firmware...
When I try to run it from adb it says something about /sys/... directory - "directory nonexistent", that it couldn't be created...
It's working now, I did it from xRecovery
Thanks, it's great... and just like hugerth says, brightness is CRAZY!!!
new version of Light Sensor Disable
i made a new version. it's got a normal bright and decrease a power consumption (i hope)
Can you write a small description on those changes, what does what ?
i write it in my post
Hi, all.
Could someone enlighten me a bit, what exactly do the light sensor do, and what would be the advantage (and disadvantage) of turning it off?
Cheers.
The light sensor is what detects ambient light around the phone and automatically adjusts screen brightness to torch your eyes out.

f*@!kin auto brightness

can someone please tell me how to disable auto brightness on
x10i eternity rom build 003
i tried using every brightness app/widget possible to turn it off but as soon as i turn it off and put the phone under different light setting i can see that the auto brightness is still on
i tried using adjbrightness but it keeps telling me that my phone isnt rooted; anyone get this app to work on x10??
please help n sorry if this questions been asked and answered before. this forum is getting too big and broad sometimes to find anything
thx in advance
Have you tried Sparepart? (That's the name)
Strange, i can't seem to turn on my autobrightness. It used to work perfectly in android 1.6. And i haven't noticed it untill recently. When auto brightness is checked, it just stays the same, even when i hold it directly under a lamp. Maby there is a bug in the software that prevents switching it on or off?
I'd also like an answer to this problem, because with auto brightness on the telephone is a battery eater.. you have to keep it to the minimum level to disable it, but when you are under a strong light, like outdoor with a sunny weather, it's difficult to see your screen's details. as you select a brightness level different from zero, the autobrightness turns on and eats the battery.
I hope I'm missing the solution to this, and somebody will help, because all the applications i've tried (spareparts included) didn't worked.
I'm quite confuse now.....
What actually do we need......
Turn it on...
or
Turn it off...
LOL
heh, so some people want a way to turn it off and others, like me, want to find a way to turn it on?
what a crazy phone..
I'm sure there used to be a tick box in the display settings to turn on/off the auto brightness. Anyway, i've tried various applications myself to get it on but nothing does it. I think the best solution is for us all to swap phones .
Spare Parts doesn't work for me, i tried enabling it, restarting the phone and jumping under my duvet.. but it didn't change
Did you update to 2.1? It was disabled in 2.1 as far as I know.
So the easiest solution, upgrade to 2.1! Else, I don't remember the menu but it's somewhere in the settings under 1.6.
I think we've all updated to 2.1 here =)
and yes, in 1.6 there was a box to tick to unable/disable autobrightness.
But, in 2.1, this feature has disappeared, leaving a seekbar and a damned widget which doesn't allow you to set or no autobrightness.
Hi,
The autobrightness is still there. It can be turned on/of from a stock SE connection widget. The different state for brightness is "minimum" -> "auto" -> "maximum"

I can get, either 0%, or 100% brightness, with the ambient sensor disabled. Anything in-between, fades constantly.
No fix for this, i presume?
Reading websites while the screen fades in/out every couple of seconds drives me mad.
Ive never had any problem with it as long as you dont lean in front of it all the time lol.

Auto brightness problem

I use wolf rom v3.8 and auto brightness function don't work. I checked other roms and it was the same. How can I turn it on?
u cant turn it on i think u need to try with power widget ..that has the auto brightness option ..works for me though, should for u too !!
Thank me if it worked !!
I used a lot of different power widgets and they show auto brightness icon, but nothing changes. Android Assistant widget has list of sensors available in phone and under Light Sensor I have: not support? wtf?
with power widget

Lesmian, why don't you try ewjet rom? So far is the best rom out there.. smoother and faster and works flawlessly, including auto brightness feature.
Is auto brightness not working at all or you just cant find the option for it? Mine works fine but no option to enable or disable.

autobrightness always was VERY subtle on my x10i, it even works "better" on my ZTE Blade, so you may just not see it, the only time i really noticed it was when i was reading on the train and drove through a tunnel.

Hmm. Maybe its true that just not see it. But I did a couple of tests. I lower my brightness and then I put phone under lamp. Nothing changes. Then I increased brightness and cover sensor with my finger, still nothing changes. ;/

Auto Brightness
I may be able to add some insight into our auto brightness problem. I know it was disabled in 2.1 apparently. First question does anyone know if it was enabled in 2.3.3?
I am currently running a generic X10i with Virgin WB 4.0.4 ROM and DooM Kernel v04b. I use Juice Ultimate Beta v3.6.6. There is a brightness control in JD and I have noticed that on my phone it says brightness sensor unavailable.
The other thought I have is that maybe it is available in x10a's and not x10i's. This may explain the wide variations in people who have it working and people who don't. I have also tried the second step (e.g. larger cirle icon) of the brightness widget in WB's rom which is mentioned in the ROM thread that didn't enable auto brightness. My phone came with 2.1 installed and I have never had auto brightness. This may also be another reason.
I might try and flash 1.6 if I can find it and see what happens. Can anyone think of a reason why I shouldn't try this. I assume I would need to flash a 1.6 basband first.
Any more thoughts would be appreciated.

[Q] WT19i / LWW auto adjusts screen brightness ?

Hi,
Since a couple of days I've noticed that my screen flickers sometimes.
Mostly when I'm moving my hand while holding the phone...
Is it possible that the light sensor auto adjusts my screen brightness ?
If so, how can I turn it off ?
Thanks in advance,
Niels
If you have rooted the phone, you can install Disable Auto Brightness for Xperia phones. or you can disable it manually editing the file /ect/hw_config.sh.
Search the forum for the tutorial
Thanks for your answer !
So unless you start rooting or changing files there's no way to stop the flickering ?
Unfortunately, no. By the way, this problem usually affects st15 models... as far as i know, you've been unlucky
Okay, I'm sure now that it's really because of the lightsensor and not just a problem with my screen.
I was standing near a window and when I put my finger on the lightsensor a few times the brightness was clearly automaticly adjusted...
I'll look for the tutorial, thanks for the info !
Other solutions, if any, are still welcome though

Hey, my ST15i does also automatically adjust the brightness....it's not a problem mate When i am outdoors the screen get brighter but when i am indoors my screen automatically gets darken
Yes I now, but I find it annoying, it gets flickery sometimes..
I want the screen to stay on the brightness I've set.
today I was wondering why this phone doesnt have auto brightness adjustment feature, because I have to manually turn brightness to zero when using phone while on bed at night. I looked into settings and no such feature found, I wonder the light sensor actually works
Yes it does, I've tested it.
Try standing near a window or holding it near a lamp and put your finger on the sensor... (The screenbrightness may not be set to 0 if you try this..)
I too find it strange that there's no possibility to set the auto adjust on/off..
Niels
I don't think there is any auto-brightness option in LWW as I've not found any. if there were any then they would have provided an check box option turn it on/off. but the brightness ups and downs happens to me to specially when i've put the brightneww to lowest level at night. could not explain myself.
yup it works (just checked thru window operation )

The fact that you can't turn it on/off doesn't mean it doesn't work. Actually, the auto-brightness is always on. You can disable it manually editing /etc/hw_config.sh or using the app Disable Auto Brightness Xperia. You need root anyway.

[Q] Galaxy S4 Proximity Sensor disable

So I'm using the CM11 4.4 Kitkat on my Galaxy S4 and recently found out that my proximity sensor isn't working (when I dial the screen goes black and won't turn on until the call is over). I've read many threads about fixing it but I think it's broken. So all I want now is to disable it but there isn't such option in the Cyanogenmod. Is there anyway to disable it, like with a terminal or something?
bump
bump!
with root explorer go to system/lib/hw and go all the way to the bottom to the last sensors file. its an so file. long press on it and open in text editor. somewhere in the page almost at the bottom you will see where it says ProximitySensor then on one of those line it should say mEnabled. just rename it to mDisabled, then reboot and the proximity sensor is fixed.

I know this is an old thread but qman66 you are AWESOME! Was going nuts trying to fix the proximity sensor problem. Ran the commands in terminal emulator that recalibrates the sensor, didn't work for me. Blasted the speaker with compressed air, also didn't work for me. But this method allowed me to disable the proximity sensor while still using an AOSP rom. I will send the phone in for warranty eventually, but I thought I was going to have to use a touchwiz rom until then (touchwiz has the option of disabling the proximity sensor in the call menu).
And I read like 5 or 6 different threads dealing with the Galaxy S4 proximity sensor issue and no one else posted this method before.

glad someone found this useful.
While this fixed the call locking problem, it also disables a lot of other hardware sensors. The only one I'd care about is the gyroscope for rotating the camera and watching videos full screen. Any solutions?

Yeah I noticed that, the best solution is to get the proximity sensor fixed in the end. Then you don't have to disable anything. If your lucky it doesn't even need to be replaced, just cleaned. For me I can live with no rotation, because the screen off during calls is a ridiculous PITA by comparison. Also apps can force landscape mode even with the gyroscope not working. I use force landscape for videos through mx player, and mango reader for manga.
I finally broke down and took the phone apart. There were no warranty stickers to break so assuming you don't mess up royally, it shouldn't effect your resale value. All it took was an eye glass screw driver and a q-tip. Once I was inside I tried the can of air first, but didn't help. Swabbed the back of the glass with the q-tip and that finally provided lasting relief.
i9100 proximity sensor doesn't work
Hi to all!
I have the issue with proximity sensor and didn't manage to find a solution in other similar threads!
The matter is that it is always stay as Released.
In the same time in test screen (*#0*#) there are changing reading for PROXIMITY parameter from 2 up to 240 with no ADC parameter at all. Please look for screenshots. PROXIMITY parameter changes its value when I move my finger in front of the sensor, but as I can understand Android doesn't recognize it because of ADC absence.
Moreover I tried to change proximity sensor for working one (from another phone), but it shows the same as mine (with no ADC readings).
After all I think it is software problem, but I don't know how to solve it. I flashed different firmwares (now it is XWMSE NeatROM v.6.4), but nothing helped.
Please assist! Thanks!

Changing the rom isn't going to do anything, even factory roms (I've tried it). If a replacement sensor doesn't fix it for you, then it's going to be hard to fix it yourself. All the posts I've seen so far have cleaned the sensor or replaced the sensor and fixed the problem. Otherwise people like me just turn the sensor off.
You were right, proximity software fix didn't help! But how is it possible to work in this (the same wrong) way with changed sensor? Can it be some main board hardware problem? But it doesn't look like this...

Samsung S4 Active w LOS 15.1 (a&Droid 8.1) - how to disable HW sensor(s).
Hi All
Hope some here will help me stay afloat long enough to learn to surf by myself; bit of a noob in this wild ocean here (more of a 'fresh water/indoor pool' kinda dude I guess) - but trying to break out of tis little pond and learn to 'surf'. Anyway, to the point:
1. HW spec
Samsung Galaxy S4 Active
GT - i9295
TWRP 3.3.0-0
Lineage 15.1 20180227 jactivelte
(sometimes with opengapps pico and addonsu15.1 but mostly just LOS and addonsu nothing else)
2. Have the sensors on phone covered up with black electrical tape - all but the notification light are covered and it's gonna stay that way - NOT negotiable!
Obvious Issue: Have the blank screen during phone call problem. Can end calls using power button but I need to use the keypad quite often so need the screen to stay on. How? Ideally want to (SW) disable most if not all hardware sensors - how?
Tried a few fixes but no luck, e.g.:
(a) adding 'the' fix/control many sensors apk no good as not suported under 8.1 (plus want to find out how to do manually myself not use 'hand outs').
(b) edit selected sensor etc ".so" (eg in system hw) files - so far not resulting in the disabled ProximitySensor.
So, I really want to hack this myself at cmd line level, am ok with that (many years IT ops/admin experience in 'fresh water commercial space'). Can mount system using TWRP then adb shell to connect and find and grep for stuff in files but cannot find setttings I need to change to disable sensors for good. Where to look/find more info?
What do I want to achive:
Make calls and have keypad stay on all the time or give me manual option to turn screen on/off with a hw button during call.
How:
I am happy to disable pretty much all sensors (proximity, gyro, compass etc) in system or firmware memory so that I am free from the overlords and really want to be able to use the keypad during calls - and have option to manually turn screen off/on during call would be cool.
Constraint:
Really want to do this from (a) cmd line or (b) edit code/recompile (learning curve) the LOS 15.1 or whatever to disable sensors for good. I will be using this old thing mostly for just call and txt not much else - and cannot be asked to buy an old Nokia handset.
Thanks,
iHAL8999.999... (hi dave...)
