[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?

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.

Auto Brightness not functioning

So my autobrightness seems to not really work, sometimes when its bright outside It seems like it might change a little but for the most part it doesn't change from the base brightness I have it set at I have to change it to suit my needs. Anyone see this problem with their phone? I had thought maybe jellybean would fix it but it doesn't appear to have.

There's a few of us having this problem. I think more would if they used their phones outside in the sun. It seems to be a JB flaw. I don't remember it happening on zv9. Although the display has always been an issue with heat and turning itself down to 63%.

I've seen this issue. Also it changes by itself going bright to dark and back again a few times a day. Does anyone else have the issue of a notification flash without a notification? Constantly flashing green led.

Taking up close pictures

Whenever I try to take close up pictures of anything it doesn't focus correctly and always come out blurry, does anybody know how to fix this problem or have a alternative? Thanks

I personally never had a problem focusing on close up pictures unless it's in low light without using the flash. Hm.. Try zooming in a little bit at a time, at the same time pull back the phone slowly.

[Q]Screen turns off when keyboard slides.

So just now my screen started flickering and it goes black when I slide my keyboard out, but a simple power on-off fixes it.
First of all, this is very tidious and annoying to do -.-
Second, I fear the screen will eventually stop working at all.
So my question, has anyone experienced this before and can give me and info on it? Would flashing a new Rom probably fix it? It doesn't seem to affect anything else at this moment, but I don't know what this little glitch will lead to.

A lil more info, the screen seems to flash on/off at the second I slide the screen up. When the screen goes black, it still works and responds to any touch as normal, but I just can't see anything at all.
Could this be a LCD problem? Or screen brightness?

Well, my gut tells me that the back light is going out, but I can't be sure. Is the screen really dark (as in, you can barely see anything in it if you shine a flashlight on the screen) or is it off (can't see anything in it at all, even with the flashlight). Also, what ROM are you using and so on?

Thanks for your help, but I'm getting used to it now. When I decide to flash a new ROM, if that solves it then great, and if not, I guess ill just use the phone till the screen blows out. This is only my media phone so its not a big deal and since the problem hasn't gotten worse over the 2 weeks I'm hoping it won't.

Photos showing up excessively white

I have been trying to play around with Manual mode, and fully admit that I have very little idea what the settings actually do, however, sometimes (a lot of the time), the picture that is taken is almost all white, and bears no resemblance to what I saw on the screen?
Is this normal or is there something up with my phone, or (most likely) am I just not using the Manual mode properly?
Also, when I am in Auto, the option for using the flash is always greyed out? Is this normal too?
Cheers

Lower the ISO and make the shutter speed faster (less value = faster), and it'll be fine. or disable AEL.
in Auto mode, hit the gear and make sure HDR is either AUTO or OFF so that you get a flash

Thanks, I will give it a try.
I had it in HDR On mode, thats why I wasn't getting a flash option.

If you are using manual mode, you'd want to read up on some FAQs. There are some really good FAQs that are out there.
The only advice I can give you is that there's a histogram and a light sensor on the very top of the bar that will help you figure out what kinda settings you would want to use.

Is it only photos taken with flash that's a problem?
If so do you have a clear case on your phone that's causing the problem.
My ringke fusion clear case causes a white washed out look when using flash because the cut out for the flash isn't big enough.
