auto brightness problems?

Unlike in 2.1, when im in full sunlight 2.2 doesnt go to full brightness so i have to take it off AB and set it to max to see the screen, Also at night with zero light it does not go to minimum brightness. Some people have said that they believe in 2.2 the max brightness has increased so i thought maybe thats why it doesnt max out automatically (maybe it goes to what the max was in 2.1 which was nearly visible outside) but the level it auto-sets in full sunlight leaves the screen not visible so either the max brightness has not increased or else the auto brightness has been altered (poorly)
Has anyone else noticed this and do you think that its attributable to it being the test version?
I also noticed that pressing the touchscreen, particularly in the browser takes a couple presses to activate a link. Im hoping this is due to the test version and not flash, i like having flash on (not on-demand) and i dont mind waiting a few extra seconds for the entire page to load, i just hope it isnt messing with the browser ui.
Again this could and probably will all be fine when the official version rolls out im just looking for some input...

I'm on 2.1 and I have found that the automatic brightness is nowhere near as bright in bright sunlight as setting brightness to 100% manually..

[Q] Please help- Screen TOO bright even at lowest setting! :( any remedy?

Hello everyone
I just got the Samsung I9000 Galaxy S yesterday and my worst nightmare has come true. I have sensitive eyes and keep brightness on all my equipment at the lowest level. I had asked someone before buying this phone and he told that it is manageable but now I find out that the screen is way toooo bright even at the lowest setting!
It strains the eyes + drains the battery.
Suppose we are not connected to internet through any source. Then if we refresh any widget we get the error "Please check your network access" and the screen goes dull in background. Now thats the perfect setting I would like for the phone.
Any idea how we can reduce the brightness even further through Mod or through factory settings or somehow?
I would really appreciate any help on this one.
Regards.

Bright on 35% level is correct.

Try fiddling with your phone in the morning, just as you've woken up. It works as a nice wake upper though. .

Android default min brightness is 8% (even though it reads 0%).
Two apps that give you less than 8%, both goes to 0% :
- Brightness Level by CurveFish
- Dimmer (Night Mode) by geekyouup
Also, look into changing your background color to black, it'll save you battery and be easier on your eyes. Lastly, the browser has its own brightness setting, found by hitting menu > settings.
Alternatively, only use under direct sunlight.

Thanks. I would try the dimmer and see if 0% helps somewhat though I have read that its only marginally better.
I am hoping that there should be a way to reduce it somehow since it gets reduced when we see some error just like I mentioned in 1st post.

I agree even at the lowest level its way to bright.
I have the curvefish brightness app, but even set to 0 its too bright for use in the darkness.

I've actually written that it's only a marginal improvement, but I omitted that opinion here since I think my opinion is less applicable to someone with sensitive eyes. You might perceive a 3x decrease than what I did, not sure if that'd still be enough.
Again, I think changing to a dark background will get you more mileage, if you haven't already done so.

Currently I am using a relatively black background but when surfing most webpages have white background and that really is painful! I guess I may have to look for some tinted screen protector!

i know this may sound strange, but If I wear my sunglasses at night while browsing it works quite well

You can also use tasker for lower brightness levels..

Sunglasses.

I am currently using "Dimmer". It takes the brightness levels from 30% (Though in settings it show minimum only) to 10%. I have also tried "Quick settings" so I guess tasker would perform the same function.
When we have locked our screen and we have to unlock we have to slide the screen. When we do that it seems like we have to slide a transparent layer of glass which is quite dark.
Now I am no developer but is it technically possible to create an app which is like a layer of tinted glass on screen so that it dims the screen further?
Regards

I haven't tried the dimmer apps yet but I DO agree that I miss my iPhone which can be set to a much lower brightness level for better privacy, night vision, "before sleep reading".
but I think it has something to do with the display technology. The OLED for Samsung may not permit such low levels or so. I am not sure...

At first even I thought that and I was worried about that. But there are some times for example when you get some error on the screen the major part of screen goes quite dull so it is indeed possible to do that technically I guess just that it cant be done through brightness.
I am baffled why did the Samsung/Android guys set lower level of brightness as option also. It would have cost them nothing and would have saved us a lot of strain and battery life.
PS: Is this the issue with Android or Samsung?

To someone with a bit more knowledge: how hard would this be to do something about? We all know the screen dims to a level that's not for the moment available to manually set some time before it shuts off, so it's got to be a way.
The screen is just too bright for me at the lowest setting - meaning it hurts me eyes (some pity here Samsung) and consuming a lot more battery than it needs to.

+1 for the app that will do this

got me new galaxy s for a couple of weeks now.. but really miss my old htc hd... the minimum backlight setting was awesome for nighttime reading/browsing.
switching on the sammy in bed in the week hours of the night makes my eyes burn! hehe.
an app to force lower or add a filter over the entire screen would be awesome!

samsung galaxy s has a SUPER AMOLED display which is why its bright even at lowest level.

Well I dont know for sure. The device has been working same since the 1st day. I guess its just that the brightness is too much for me. As far as the screen is concerned I didnt notice anything significant but any easy way to check about the problem?

[APK] Official Thread for Keep The Lights On 1.3 (Free Version)

If you want to donate, or more features, check out Keep The Lights On Pro.
What does it do?
Keep The Lights On is a simple app that performs one function. It keeps the LEDs behind the buttons on a Captivate or similar phone on while the screen is on.
That seems stupid, why would anyone do that?
Well, try finding those buttons in the dark. While the stock ROM turns on the LEDs when you touch the screen, the i9000 based ROMs do not. In addition, most i9000 ROMs have a timeout of 3 seconds.
Doesn't that waste battery?
Depends on what you mean by waste. So first you have to understand the scale of battery consumption I'm talking about. LEDs, especially surface mount ones, draw very little power. How little? Assuming typical LEDs, we're talking 5 milliamps at 3.3 volts. Given that there are 4 LEDs, that means the total power consumption is 0.005 * 3.3 * 4 or 0.066 watts. The CPU consumes between 100 and 1000 milliamps, again at 3.3 volts meaning it uses between 0.33 and 3.3 watts. That's 5-50 times as much power, and that's before adding in the backlight, radio, etc. While yes, technically this uses a little more power, the scale is so small that for all intents and purposes it isn't going to make a difference in your life. Seeing the buttons clearly though, that takes frustration out of your life. Seems like a reasonable trade off.
Does it work with other BLN things like Blinky or BLN Pro?
Yes. This uses a different way to handle the BLN than both those apps. In fact it only requires a rooted ROM with these lights to work. So that means it should work for i9000, Fascinate, Captivate, Vibrant, etc. This should even work with the stock ROM given it is rooted.
If it works for all those phones, why is this just in the Captivate Section?
Well, I only have one phone right now to test with. That is my personal Captivate.
Why are you giving this away for free? Are you drunk? Does it use ads?
To answer the second question first, sometimes but not right now. This is free because I like making people's lives easier. I do not believe in advertisement based products, so you'll never see that from me. If you want to give something back, consider the donate button or buy the Pro version.
I installed it but didn't the app in my list of apps. Is it broken?
Short answer, no. This is a widget based app. Simply add the widget and click it to change the light behavior. You can even remove the widget and it'll remember your preference when you start up. That said if you uninstall the app you'll loose the behavior.
I just got an invalid signature error. What do I do?
This is my fault, there was an early version that I didn't sign correctly. Simply uninstall it manually before installing this version from the market.
What other issues exist?
Well there's a few:
I've had one report of the lights flashing instead of staying solid when turning the screen on. If this user hits one of the buttons the lights will stay on. I'm working on a way to fix this, I haven't found the cause as of yet.
There's a superuser notice every once in a while. This is easy to turn off in the superuser app, and will be fixed in the pro version.
There's been one report of clicking a link in andchat causes the lights to go out. I haven't been able to reproduce it yet.
If you find a problem not on this list, feel free to let me know.
What other features are in this app?
None; however, I'm always open to new ideas. Be warned though, they may go into the pro version.
How do I get this app?
From the market, or here:

Great widget....downloaded it this morning.
Sent from my SGH-I897 using XDA App

using the paid version, much thanks!

Suggestion
I have not tried your app yet, but I have a suggestion.
If you could turn on or off each individual LED, rather than all on or all off, then you could consider using each button to indicate something different.
Home - new email
Menu - new text
Back - missed call
Maybe you can even make them blink?

What would be the point of that with this app.....it turns the lights on when the screen is on, if the screen is on then you have those same notifications at the top of the screen already.
Though I guess it might be useful for some if those additions were made to Guardian Bob's BLINKY APP.

Support for Galaxy Tablet
First off, thanks for your efforts!! This is exactly what I'm looking for.
Any chance you will be able to support this on the galaxy tablet? I am happy to help in any way I can - I am a developer (though I haven't done much android development). I have a rooted device with busy box... if there's anything I can do to help you figure out this device, please let me know!

Crazy me, I would honestly like to be able to DISABLE these lights. I watch movies and do other things a lot in the dark, and these bright white lights randomly popping up on my phone are very distracting. Since they can be turned ON manually, does that mean perhaps they can be turned OFF as well?

In a su'd terminal enter this:
Code:
echo "0" > /sys/devices/platform/button-backlight/leds/button-backlight/brightness
Change the 0 to 1 to re-enable.

Lovin it. One of the pet peeves of this device was the short duration on the home keys.
How about this as as Pro suggestion (if possible):
Control brightness level when LEDs are on.
My cuz has a DINC and i absolutely LOVE the brightness of his home keys. Super easy to see. Possible?

works on Korean Galaxy S shw-m110s, maybe the least compatible of the SGS versions, cheers.

Working fine so far on my Vibrant running Nero v5.

Good job, but i was wondering if there's an opposite app, one that turns off the led buttons even when the screen is touched? What for? For reading ebooks in the dark, the led buttons hurt the eyes even when the screen has been adjusted to the lowest light level. Thank

Great app, just what I'm looking for, but I can't seem to get/or find the widget. I installed the free version, but the "open" is greyed out. What am I doing wrong?

It's a widget, long press your screen, select widget, select KeepTheLightsOn.

FYI -
I'm working on tasker support for the pro version right now (well not right now, I'm taking a moment from that work to update people) but when I finish this I'll continue working on my beer, watching the Packers vs the Bears and keep working on adding tasker/locale support.

Mine stopped working, Not sure why. I have the widget and it will light up or un-light. But it will no longer keep the lights on. Any suggestions on figuring out why ?

Same here. using the most recent speedmod kernel and doc's kitchen rom. (i have the pro version)

Well you can rule out the latest speedmod kernel (Q) and Phoenix 4.1 because that's what im running and my KTLO still works fine.
Sent from my phone from the future running on Phoenix!

something about brightness that the answer doesnt exist on the internet.

Hello programmers, love this forum since i know it 3 years ago...
the BIG question i have is;
i switched a broken s3mini screen to a new one.
everything working fine till i slide the brightness tab down.
every click it slides down, the screen turns into a color, as if absence of color calibration, or intense of certain colors making the only brightness option i can choose to see accurate colors is on max.
i updated the firmware to latest, still no results. its an original never rooted 8190.
thanks in advance and great work!

Is your new screen a Samsung genuine? Or is it 3rd party? It could be incompatibility. If you never changed the firmware and it was working before the new screen, but not now, it's probably the new screen.
Good luck!

Screen settings/brightness/and such

hey all,
I have a 360, and picked up a R to try out (I like that it looks like a "normal" watch). One thing I have been tinkering with is the screen settings. I like the "ambient" mode on the 360, which I guess makes use of the sensor. With the G, so far, all I can see if on or off. And even with the brightness dialed down to 1, it still seems pretty bright at night. Has anyone found this to be an issue or to address it? I have a little time to decide which I want to keep.
Any other advice for the watch would be much appreciated as well.
Thanks in advance!

With Wear Mini Launcher you can setup brightness below Level 1.
With "SWApp True Dark" you can setup brightness from 0% to 100%.

Thanks, I will give it a shot. Can you automate the timing of the brightness level? So, now when it gets dark at 5pm, adjust?
Thanks again

It has a trigger setup for night but not understand well how it works :
Seem to automatic dark after "x" minutes between "00:00 To 00:00" so you can go dark 1 min after no interaction between 20:00-06:00 I think.
