[Q] Jeff Sharkey's AMOLED "night mode"

Has anyone attempted to/willing to try to implement this on the Captivate?
jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/

This is really interesting. I'm into astronomy and it would be awesome to not have the phone blind me everytime I turn it on during an observing session to use it for google sky and the atomic clock.

Apparently no dev types are interested enough to tell us that they are not interested.

No doubt.
This thing is blinding even on the lowest brightness setting.

Yes, the brightness is pretty ridiculous. Is this because of the AMOLED screen? Can't set brightness below "blinding" due to no backlight?

I have heard that the leaked I897UCJH2 rom has a lower mininal brightness; which might help with the blinding brightness at night, and also helps bettery a bit.
Not sure if you guys are interested in leaked ROMs but I'm sure if Samsung does not release it that a cook will make a custom rom from it.

looks awesome

Bump.
I think this would be extremely useful.

/agree to post above me

Me too. I'm jealous of the iphone star map program. The authors were smart enough to make it all black and red. You can tell none of the google authors star gaze in their spare time with all that color.

on Google sky map theres a night mode option when you press the menu key.

I seem to recal hearing that at a certain point when the voltage is too low the screen will still work, but you see glitches/artifacts.
So im assuming this is why the min brightness is set where it is.

There is that very low brightness that occurs when you have less than 10% battery life. I wish they would make that brightness user selectable.

Even if the screen cannot be physically set below a certain level of brightness, it would be trivial to have the OS do the equivalent of putting a partially-transparent black rectangle over the screen. Sure, color fidelity would suffer, but it would be a welcome option anyway--I have seriously considered wearing sunglasses in bed.

wow, i think your right.
instead of trying to set the brighness lower just put a transparent gray object that sites on top of all the windows.
It would have the same effect and save tons of battery.

You can!

Search for a widget called Curvefish Brightness Level in the market. Set it to 0% brightness, which appears to be the same as the low battery life brightness.

Im using extended widgets too, mine goes as low as 1% but i think thats still the systems native low brightness Voodoo goes even lower...

Just slide your finger along the notification bar.

app called "brightness level"
set to 0%

Interested in this as well.
I think we are actually looking for something lower than 0%
It is probably the amoled screen vs backlit one, the way they operate. 20% on lcd is much lower than 0% on amoled.
Maybe there is some kind of overlay that can act as Rayban? Like ie when you do Titanium backup, you can see the rest of the application being much darker than the notification that pops up. Probably some overlay being used.
Maybe some of you asking yourself why, but try using it in complete darkness for awhile and you'll see what I mean.

Thats what i mean like a torch in the night.
I had tested all brightness apps in market but no one goes lower.
Thanks for help.
Mybe a dev or supercurio can help to explain

Yes, the lowest stock level is already quite bright, too bright of course for night use in bed.
You'll also notice that the colors & contrast looks quite dull on the lowest stock brightness settings, with a color deviation in the red shadow colors.
With the revamped Voodoo color which will be released step by step during the next weeks, you'll be able to go so "dark" (if chosen) that you'll be almost not able to see it in the dark even when on
All that, preserving color accuracy and color temperature (which goes more red when you lower the brightness on stock)

does this app go lower than "Dimmer - Night mode" ?
Dimmer shows it goes from 30 (lowest stock) to 10...

moved this is not a Dev topic

screen too bright

hello my s5 mini, when exposed to sun for example, automatically increases the screen brightness...altought so much bright that even the colors became strange. anyway, since i am rooted, to change the maximum brightness allowed in auto mode?

I've just read an article pointing out this weird thing:
http://www.androidcentral.com/samsung-galaxy-s5-mini-review
I've just tested this on my S5 mini, wow! I see what they mean by colours going psychedelic.
I don't think you have any control at all under Auto Brightness. You'd have to switch Auto Brightness off then slide the brightness to Max.

maybe some moding?

Maybe this is due to a feature named "Adjust Display". Go to Settings > Screen > Screen Mode. By default, it's set to Adjust Display, so the screen will automatically change its colors depending on ambient lightning.

How do I turn rear camera custom color tone off?

Could someone be kind enough to share how can I turn rear camera custom color tone off. I'm not exactly begging, well actually I am.
The reason is so I can save RAW (DNG) pics. Many thanks.

There are two settimgs that change colors, white balance and HDR, the later,, you can turn off, or, what do you mean by custom color?

Yeah, I am wondering what the op means too.....

Stock blue light filter color

Is there a way to decrease the color temperature using samsung's stock blue light filter?
I tried using twilight but it's an overlay and very inconsistent.
I wish I could make the color warmer.

yes you can, drop down quick panel, then keep pressing blue light icon, it will take you settings to adjust it intensity, schedule time on/off.

Thank you for your answer.
And I should have described it better.
I mean even warmer than that. I already have it in the highest color temperature value in the settings.
But still I find it quite not warm when lowering the brightness.
Anyways thanks for the input.
