[Q] CM7 Light sensor issues

Hello,
I recently bought an Incredible for my girlfriend on craigslist. It was only 2 months old (in great condition to boot). Either way after flashing CM7.0 I noticed that the automatic backlight setting did not work. I just set it to around 25% and figured I would figure it out later. After 7.0.2.1 came out I flashed that and no change. I then decided to figure it out. It seems that after waking the sensor doesn't work unless really flooded with direct bright light (such as the flash light from my incredible). After that it works mostly as intended.
Here is how I tested it. I lock the phone when in the custom light levels screen. When unlocking the Sensor (filtered / raw) is at 10/10 and will not change no matter what I do until I hit it directly with a bright light. I believe that it will also change eventually letting it just sit. Most of my tests involved using bright light sources. After that the sensor works just fine and changes almost instantly when I cover it with my hand and then move it into regular room light. Is this a known issue? I checked the bug tracker briefly but did not see anything. I have had two others test. One had fine light sensor response the other had the same issue as me.
Anyone have any idea?

I've noticed that the automatic brightness does work, but at the default levels its way too dark. Had to go info the menu and bump up all the levels and it's alright now. Doesn't seem like it works quite as smoothly as it does on sense roms but I haven't gone through and tweaked everything perfectly, I honestly don't understand all the adjustments that are available.

It does work but the sensor doesn't respond in a timely fashion.

Have you tried changing the sample interval?
Sent from my ADR6300 using XDA App

What settings are you using? I.E. do you have filtering enabled? What is your window length? Sample interval? Etc.
I've never seen anyone discuss this as a CM7 bug. Based on the way you are describing it, it sounds like you might just need to tweak your settings.
For example, if your window length is very long and sample interval slow, that might be why your readings are taking so long to update. As for why the reading changes as soon as you hit it with a bright light, you could be tripping the reset threshold.
Just in case you haven't checked it out already:
Numerical explanation of the CM7 automatic backlight settings

I will check when she gets off work. All I did was flash cm7. I didn't mess with light sensor settings.

Ok... I have checked it... Not good. Sample intervals were set to 1s. Even still they were not enabled. Messing with the settings didn't yield any results either. It was still sluggish until hitting it with bright light...

I would search, there are multiple threads around where people have posted their settings, I would try those then tweak it to your liking. Also check out byrong's thread, the man knows his stuff.

The automatic brightness sucks on stock as well. Just turn it off. You can't see the screen in bright sunlight no matter what the setting is, and you can see it just fine at 64/255 inside. All the automatic brightness does is give you a headache.

[Q] Softkey lights problem after installing .zip from UOTKitchen

Yesterday after installing a zip from UOTKitchen i noticed that my softkey lights would not turn off! Normally they dim after about 15 seconds but they would not turn off at all. Not only am i concerned about the battery life but it is also quite annoying. One more thing is that now the keyboard lights will not turn on! Any help appreciated!

What is uotkitchen?

This happened to me as well. I'd be very interested in a solution.
So far I've tried restoring old backups w/ data wipe, reinstalling CM from scratch w/ data wipe, and formatting the system folder from clockwork.
I've also tried changing the CM backlight display options as well as the automatic brightness and none of it is working =/

I tried changing ROMs completely (Pure Stock, GingerSense, etc) and it fixed the problem. But when I switch back to a CM ROM - regardless of which version - the problem returns. I can't explain why this is happening now since it worked before and why other ROMs fix the problem.

I've tried switching ROMs around noticed that the other ROMs are also exhibiting backlight issues although not as blatant as CM.
The sensor appears to work properly since the backlight is fine as long as the LCD display is on. So since this now appears to an issue with my /SYS files, is there a way for me to get a new version of them or something?
Any help would be great.

Checked out the files via ADB. When the LCD display is on, I can adjust the button backlights easily.
Once the screen goes off, I am no longer able to adjust the lights. The 'brightness' file is set to 0 (as it should be) but the light is very clearly on. Editing it to other values does not change the intensity of the light.
Since this seems to disprove that there is something wrong with the /sys files, I can only assume this is some weird hardware issue now. I guess it's back to T-Mo...

Softkey backlight?

I love the DINC2 so far, but one thing that I wish I could change is the softkey brightness.
Are they supposed to be always on? Even with the clock in night mode?
I tried LED hacks and a few other brightness control apps, but no luck so far.
Does anyone know of an app that can dim/turn off the softkey backlight?

LOL just flash virtuous 2.35 softkeys don't work, but everything else does. No softkeys lighting up is not all that bad.

That's an idea! *g*
If I get desperate and there are no other solutions, I might try it.
Does global mode work with virtuous?

Nope

Well, so much for that!
Thanks for letting me know.

what rom are you running? stock? on cyanogen mod the softkeys go out on night mode in the clock app.

Right now I'm running the debloated stock, but am thinking of skyraider zeus.
Had it on there yesterday, but then lost mobile service after unlocking the SIM, and decided to try the stock rom. Service came back, and now I'm chicken to try flashing again.
Does global mode work with cyanogen? I will use this phone in Europe later this year and want a stable rom with working global.

According to post #18 SkyRaider Zeus does work in global mode. I haven't tested it, but I have been running SkyRaider Zeus for about a week now and I love it.

Yep, that's part of the reason I want to use it, but I'd like it even better if it had softkey backlight control, too. I guess I will have to risk flashing and seeing what happens with the softkeys.
When I ran it yesterday, it was bright daylight, and I only noticed how annoying the backlit keys were later that night, when the phone was running debloated stock.

There's no risk flashing most stable roms from the dev section. Make sure you have a working backup of your current rom and you're good to flash new ones. I had an issue trying to mess with global mode on my phone once and it required me to do a restore of a working backup I had then all was fine again.
Also in the cm7 thread this post confirmed working global mode recently. http://forum.xda-developers.com/showthread.php?p=17245922

Thanks for the info!
When I ran into the no service problem after unlocking the Sim, I restored via cwm, but nothing
worked. Got an endless 'loading, this can take several minutes. Please wait.
This was the backup of the stock ROM, though.
Sent from my ADR6350 using XDA App

if you had issues restoring a backup in clockwork then it wouldnt have been because you unlocked the sim card. sounds like you had a corrupt backup or something went wrong with the backup you were trying to restore. but out of curiosity, how long did you let it try to restore before you gave up?

The restore went through successfully, according to CWM, but when the phone restarted, I was stuck with: Loading! It can take several minutes. Please wait.
I waited for an hour, and then flashed the debloated ROM.
What happened after the SIM unlock (I was running Skyraider Zeus at the time), was that I lost my mobile service.

I am sorry to hear you are having problems. I hope you didn't lose any data. I run cm7 nightlies. I have heard that cm7 supports global mode. I also use an app called "Screen Filter". When I was unrooted/stock, the app would not turn off my softkey backlight (there is an option to enable or disable softkey backlight), but on cm7, the feature works. I have two widgets, one set at 46.8% without softkey backlight, and one set at 97.8%, also without softkey backlight. The second one barely dims the screen, and turns the softkey backlight off. And best of all, with cm7 I am able to assign one of them to long press search key, so I can turn off the softkey lights from anywhere. I have not tested it, but there is a chance this could work on a rooted sense rom (the screen filter setting). I know it works on cm7 though.
Also, with cm7 you can control the brightness of the softkeys (if you only want to dim them) if you customize the auto-brightness (the setting is built into the rom), but then you have to use auto-brightness (I do that as well).
Hope that helped!

Thank you!
You don't know how happy it makes me to hear that cm7 does global and screen filter works with the softkey backlight!
I'm a big fan of Screen Filter, anyhow.
Can you tell me where I can find the latest stable version of cm7 to try out? Or do I need to grab a nightly?
Any ideas on battery use, and signal strength with cm7? I have pretty horrible signal strength with the debloated stock rom, though it was no better with the unrooted stock.

There is no stable version yet, but here is the link for the nightlies:
http://forum.xda-developers.com/showthread.php?t=1156343
I find them stable enough for daily use. I have used WiFi, GPS, Bluetooth, 3G, Tethering, SMS and MMS with Handcent, etc. and have never had any problems (other than the compass issue with AOSP, which I really don't mind, as it's fine when I'm moving).
There is also a beta:
http://forum.xda-developers.com/showthread.php?t=1153261
if you don't want to deal with nightlies. I haven't used it, but I have heard it's good enough for daily use.
I do have pretty bad signal strength with this rom, however I have always had bad signal strength and have never dropped a call/had to resend a message. At best I can get around -80 dbm, but usually I'm around -90.
My battery use has been okay. Not 72 hours like some people report (I don't see how that's possible with any rom), but with ~2 hours of screen on time, I'm usually just below 50% at the end of the day. So I charge every night, but I never worry about making it through a day. I use the Tiamat kernel because without it the speaker on calls is too low for me, but another benefit is that Tiamat includes the smartass governor, which is supposed to help battery life.

Thanks again!
I'll check out cm7.

Yes! It works!
I have the latest nightly and screen filter controls the backlight!
Thanks a million, and also for mentioning the long press option.
Now I use that for turning off the soft keys when reading. Much nicer than having to go back to the home screen.

[Q] cm9 buttons dont illuminate

I installed cm9 after using cm7 and cant get the four buttons on the phone to light up. They are accessible but not illuminated. has anyone else encountered this problem.
Also I was wondering if the Cm7 uses more battery than cm9

You have to use auto brightness.

cm9 illumination
If you mean display auto brightness ok but when I'm outside I can't see the screen...guess ibhave to toggle back and forth. I had switched back to cm7. In your opinion is 9 worth changing to. It seems like in 7 everything is working pretty well.
Thank you for the reply

Toggling auto brightness on and off solves it. Just tinker with it..

Ive been using the dinc2 since last July and I got used to the buttons to the point that I noticed they didn't light up, but until I saw this post, I never considered it a "problem". Since I knew where they were and didn't need to see them to use them. If they ever do "fix" this issue I hope they allow for a settings option to keep them turned off. I actually enjoy them off, in my mind its just one more security feature. I know when my wife tries to use my phone she needs to see them, and since recently rooting to CM9 I don't want her bricking my phone. Because of the unlit buttons she has stopped using my phone (she uses some cheap AT&T phone, refuses to switch to Verizon). Just throwing my opinion in the mix. Thanks for the post as well I wasn't sure it was intentional or not.

I believe in the advanced brightness settings under CMSettings you can do just that. Whenever I run a CM rom, I always go to the brightness settings under edit Other Levels and set all the softkey values on the far right column to 255 so they're always the same brightness and look nice. I like the sheen they have, but I can only see it when they're close to full brightness.
If you did the opposite, set all the values to 0 and then click Save and Apply Values at the top of that screen, they should, theoretically, never turn on.

Thank you ....as I am new to a rooted phone and this forum I didn't know those adjustments were available...learn something new everyday ......
Does cm9 drain the battery alot quicker or is it unnoticeable

Unfortunately, I can't answer that question for you, as my phone doesn't like our ICS builds. Until we get a leaked official kernel and some source, I'm SOL.

Where exactly are these settings? Running CM7 with the same problem as the OP and can't find it anywhere. Edit: found the settings and putting them all at 255 didn't do anything. Any other ideas?

Is backlight of touch input dynamic?

Hey all,
I experienced something a few mintues ago. I installed a new rom, Blissdroid. I 'discovered' that the backlight of the touch input (under the screen) was reacting dynamicly to sunlight. It went off in full sun. I couldn't find a setting to let it lighten up all the time.
I went back to Virtuous Unity, 2.35. It seems like the same thing is happening. I don't know if it's just normal (and I never discovered it before) or is there a setting I have to change (because I can't find one)?
Someone who can help me?
Thanks!

I tried that, didn't work.
For you it is always lighten up, even if you are outsise/inside where it is really bright? When I go outside, full sun, those 4 touch inputs will stop shine. It seems there is something wrong with my DHD? Or Am I mistaken? Someone who can confirm it is always lighten up?

Oh, so it is just a normal feature of DHD? Weird that I just discovered that yesterday

rcmix 4.0 and roms that use rctweaks have settings for this. alternatively you can set it to your exact preference if you edit framework-res according to this:
http://forum.xda-developers.com/showthread.php?t=1034743&highlight=systemui+apk
the link is manly aimed at tweaking your autobrightness, but it has info on butons too

Thank you. I only feared a problem, caused by changing ROM, as I never saw that before. I Thought those inputs were always lighten up, in every dark/bright situation.

depends on rom authors preference i suppose
if you are using sense 3.5 runnymede port, you can also flash tweaks as addon. some very nice features in there

Thank you all. I'm not great in flashing ROMs, certainly nog all those tweaks. I tried Virtuous Affinity and Blissdroid, but in both I heard a pop sound after playing music, sound, ringtone,... It seemed like I was not alone.
So I went back to Virtuous Unity 2.35, which doesn't give me any problem, except for a random bootloop from time to time (for example after playing Angry birds and once just after sending a message) what I can fix by replacing the battery. This happens 1 time in 3 months or so.
I just don't want to brick my phone, so I don't experiment much. Maybe one day, when I've got a new phone, I can use my DHD to experiment more.
