When (if) we finally get this baby S-Off and devs start cooking kernels, will they be able to tweak how bright the capacitive lights are? On my device, at least, the lights are so bright they look a little pink. Is that something controlled by the kernel? If the brightness on them was dialed down, I feel like it might help.
Rabble rabble rabble.
I believe that's something that will be able to be fixed via software.
Absolutely. That's can absolutely be incorporated into the kernel. If a dev makes a configurator for the terminal emulator th u can adjust it by a percentage. We had a few configurators for the EVO and the settings were for both OCing and the capacitive button. Very useful

Devs can tweak the Capacitive brightness through kernel, Evo 3D & Sensation both can change their brightness. But there's a script that lets you change the lights from bright to dim and then off. Although Faux has managed to make the Leds dynamic based on the screen brightness, which is quite useful.
Having a dynamic ability would be great! However, 9/10 you can see the buttons without them being lit at all.
I couldn't care less about the brightness, I more hate they're so inconsistent. At home with my incadescent lights, they never come on. At work with all of the flourescent lighting where it's much brighter, they do turn on. Makes no sense man!
Could just be the lighting the sensor is more sensitive to.

Sounds pretty consistent to me. Sorry, couldn't help myself.
Yeah, I had the EVO 3D for a few weeks, and when we only had temp root I did a lot of playing around with terminal scripts, for OC and whatnot. But this is good news! Like somebody said, you rarely actually need them. But when you do, they don't even need to be very bright at all to be seen. I feel like at stock levels, it is a little overboard.
I think even having it at 50% would be more than enough. Anyway, thanks for the responses. Looking forward to such development.

i usually want my led lights as bright as possible, but i know from taking it apart and lighting it up, its pretty much as bright as the led will go, its just the tint of red on the digitizer is thick enough so the light doesnt shine through pink like you said, however maybe on yours the tint is thinner who knows. I usually change phone everytime a new one comes out, or else i would (which i still might) solder on RED leds so i can push them out even brighter red.
Led Notification ?
Speaking of lights, does this phone have an led notification light for missed calls, voicemail, texts, etc?

I agree, the capacitive keys are too bright and look pink-ish. If we can adjust them to make them dimmer, make them more of a true red, that would be awesome.
My lights are on whenever the screen is on. Is there a way to change it. I have seen post talkin about them never turning on but I rather they never turn on not always be on.

Download an app called Screen Filter. Set it to 100% to keep the normal brightness, then uncheck Enable soft key lighting option. Screen on even in dark with no capacitive lights.

Hopefully we can disable the red key backlighting with the kernel source. As of right now, I am not too keen on it.
I don't think we can. The keys are red even when the phone is turned off.
I mean the backlighting. The red isn't as bad until they were lit up. I wish they could make a phone with blue stuff instead of red.
I like the red. And it wont mess with night vision as bad as the white ones on my incredible do.

That's what I'm thinking, and liking. The white ones on my Incredible are too bright sometimes, especially at night and/or when watching videos. The red ones seem to be less bright, which would be nicer

agreed, the red ones are going to be great. At night it won't blind me so that I can actually see my autobrightly dimmed screen, not to mention it looks sweeeet.
White ones could be argued you could see better in daylight.. but then you don't need backlights in daylight?
but with all that said, I'm sure after development ramps up it'll be able to be turned off.

I'm kinda confused on that though, like if you see it while it's turned off, the buttons are still painted on as red.. err not painted, but you know what I mean. You can see it in this video http://www.youtube.com/watch?v=7rtCXb9Qays&feature=player_embedded
I've read of several owners complaining about how bright the lowest brightness is, and others (including myself) on the dark 'splotches' on the screen in very dark settings, only recently have I pieced the two together: Motorola purposely made the minimum brightness still very illuminated in order to try and hide these marks on the AMOLED screen. It's very annoying when these are visible, and it's even more annoying trying to read or accomplish any task in a very dark setting; the screen is still so bright that it hurts my eyes.
I hope Motorola fixes this hindrance in future iterations of the Razr/Droid series.

That makes sense
This makes sense. I too have noticed the dark splotches and I thought I was the only one who received a somewhat defective one. But for me, as long as I'm not looking at a super dark image in a super dark room I cannot notice them.
But thanks for the reassurance that I'm not the only one!
Does not make sense at all - how low would the brightness have to be to see those spots if they are only visible on black background in COMPLETE DARKNESS?
Yeah, you have just discovered America.
I have the same. I only see them when the phone is docked and in night clock mode, or when I'm running screen filter to cut the light when playing something in bed.
Never seen them. Not that big an issue if they're there.

If my brightness is set to minimum and it's nighttime, when watching movies, looking at pictures, or even just navigating around the OS, I can see them, they look like water-marks on the screen.
"you have just discovered America." Is that suppose to be an insult?
Hello,
Im Using Amoled Smartphones since the Galaxy (i7500). They all were always showing at 100% Brightness for Black parts of a picture a true Black like the Display is OFF.
If you put the Brightness to 100% and go to an complete Dark Room and open an Black Picture you see some Gray/Yellow Tint on the Screen. You can compare this good by locking the phone to see the Screen OFF and than unlock it to view the Black Picture again. You should see a huge difference. Hope to hear from your experiences.
I've seen that already on the S1 when abusing it a a nightstand clock.
Best guess I've heard is that the (AMO)LED screen leaks some luminosity to other pixels in the background which is then visible as a very faint glow.
However I rather believe that the AMOLED are not truely off but rather get some leak voltage and thus have a very-very-very faint glow (like one photon per second xD )
That would explain the black spots most people seem to mind on AMOLED when on minimum brightness with a black screen; they are truely off or without insufficient leak voltagage (LED's requie a minimum voltage to work).
AMOLED production is somewhat complicated (very thin layer of silver as a power source and a control-layer) so I wouldn't be surprised if the above is true.
Nothing is perfect, especially not a rather new technology.

Yeah so I was wondering why it does this little/ hard noticeable yellow/gray tint on a dark room...
There is no Backlight... Unfortunely i Sold my Galaxy S2 so I cant compare it.. But im Sure it wasnt like this
I have this on my gsiii and also on the Gnote... I think is due to the pentile screen
I had this on my Fascinate but realized it wasn't a big issue. Definitely more noticeable on my Gnex but it also has more pixels so that could be why you see more light. I wouldn't call it a problem because the majority of the time it's absolutely unnoticeable. Each pixel has so have some sort of voltage to be ready to react to changes. Turning off/on completely each time light is needed might waste battery.
P.S. I'm noob at displays but that's my theory.

I was curious about this issue as well. It's my understanding that OLEDs do not produce any light in their inactive state.
Regarding your theory, I wonder if it's similar to plasma displays. Even though plasmas are capable of true black (they do not use a backlight) The individual plasma cells have better response times if they aren't fully discharged on blacks. So they have a faint glow that comes from the low power they are using to keep the pixel charged up and ready to go when a color change is needed.
This actually costs a little power though, rather than saving it. So if thats what they are doing, it is for screen quality reasons so that movies and other things look better.
Did some Googling and I couldn't find much information, but there is talk of delivering pre-charge voltage to the OLED pixels to improve response times. So it could be that they are indeed similar to plasma displays in that respect: Capable of true black, but the benefits of not using true black are too good to pass up.
Are you SURE the picture is actually true black? By that i mean pure 100% black in an uncompressed image? If not then you cant expect the phone to display true black. A JPEG of black may not be enough.
My screen it totally off when displaying true black.
I can confirm the screen showing a faint glow on S3 with a true black screen.
Use Firefox with Fullscreen extension (Chrome and the default browser don't seem to have fullscreen mode yet) and go to http://d4f.pf-control.de/black.html
That's rendered on the phone so we can expect it to be the blackest black an app can produce, however in a (very) dark room you'll see a very faint glow coming from the screen and you'll be able to see the black spots (truely black) that people keep complaining about.
The theory about it being a precharge voltage does indeed sound plausible since LED's have a certain reaction time which unfortunately cannot be compensated by e.g. Overdrive as is used in LCD screens.
Note that the S3's "black" is still far better than any LCD.
No mine is still jet black, no light at all.
Go to a COMPLETELY dark room and make sure the screen is actually turned on when on the website (not timed out).
Then take a long-exposure photograph of your phone (still make sure the screen is turned ON!).
I don't have a long exposure camera, but the room is completely dark and my eyes have adjusted, there is no light.
All sgs3 ( as sgs2) screens emit a very week glow on a black pictures ( with the screen on )

It would seem to me that the 'ink spots' many have are not overly dark spots at all, they are what the screen should be. My screen emits no visible light when displaying a true black image, at least nothing my eyes can see, even at the edge of my vision field where light cell are most sensitive. My screen is on maximum brightness.
My screen has no patches, no streaks, no spots, no pink or excessively blue tint. I guess i have a screen thats as near to perfect as they get.
yes there is very faint glow indeed making the screen a bit greyish instead of pitch black

I don't think anyone is trying to paint it as an issue that needs to be resolved. It's more of an odd technical mystery rather than a real problem. The blacks are still extremely deep on an AMOLED, just like with Plasma it puts LCD to shame in that department.
Found other similar posts in Q&A. I have to cover the light sensor or be in pitch black to get the buttons to light up. Anyone else? One guy already swapped for a new phone but same problem.
Yep its pretty much hit and miss with this phone. I had to exchange my first one for a different issue, but the capacitive buttons on both don't light up unless in really low light. Personally I like this as I would turn button backlights off with CM based Roms on other phones. I know where the buttons are, don't need them to light up.

I was wondering the same thing. Mine only light up in very low light or dark. Unless there is a control for it, it is a bug
Sent from my HTC6435LVW using xda premium
I'm not so sure it is a bug. It seems equally possible that they only turn on in extremely low light by design. HTC might assume (and rightfully) that you know where the buttons are after a while and don't need them illuminated unless it is dark enough to not see the phone very well or at all.
Personally, I'm glad they don't light up a lot. I know where they are, I can see them fine in low light and I don't like when capacitive buttons are always shinning at me when I don't need them.

I think it is a battery saving feature. Why would you need them on in the light anyway. They are not invisible like on the note 2.

I've got the same problem. The phone has a problem. I installed AndroSensor on the dna and my razr. The dna consistently gives me false readings. If there's any light at all it gives a 200 lux reading. If you are in total darkness it will reset. That's why your work around works. The phone has a light sensor that, either by design or defect, doesn't differentiate light levels between 2 to 200 lux. It defaults to the higher figure and the cpu apparently uses this figure to shut the lights down.
Personally, I find this to be a little too convoluted to be an energy saving design. I believe it's a bug that a future update will deal with.
Same here. Also.........they arent bright enough!! Lol we need a mod for this. Ill get right on it.

Anyone who consistently uses the phone in a dimly lit room will want it fixed. I watch movies with a single low-watt lamp on, and I like to use the phone periodically. Having the lights off means that every third button press doesn't land exactly on the capacitive part. If I force the lights on by covering the sensor, I never miss. There's very little play on the sensor area, so you either land perfectly or not at all. Definitely looking forward to a fix. I just hope it's not a hardware glitch that can't detect 2 to 200 lux.
Back during the HTC Incredible days, we had the torch app (same one our aokp uses) except their EXTREME brightness mode actually made the led 3x brighter. On our rezound it makes no difference if you select that option or not. Is it possible to make it work?
I don't think the phone has control over the voltage sent to the LEDs.
If it does, then that is something on the kernel level. But I think the LEDs are very bright as they are.

The LED's on the rezound are cranked up so high I can't imagine multiplying it.
My incredible can illuminate half a stadium. It's so bright that even if you took any other 3 phones, put them side by side and used their LED's, my incredible would still outperform them.
While I agree the dual LED on the rezound is bright, there have been situations where I wish it could go brighter.
People were always impressed by my Incredible LED brightness.. So far I've gotten no compliments on my Rezound LED
