[Q] Dark screen app (?) to reduce brightness? Is it possible?

Hello
I have a Samsung I9000 Galaxy S which is way too bright even at the lowest setting.
Anyways so I got an idea of an app but I dont know whether its technically possible or not!
So is it possible to create an App that works just like a transparent dark glass which covers your screen and you see through it and can perform all functions normally but due to the app the screen becomes dark so that it doesn't strain the eyes?
Also current "minimum" brightness on the Galaxy S is "10" even with 3rd party apps. Is it a limitation of Android or Samsung firmware? Also is it technically possible to go into - values such as "-30" ?

Ah, great topic. I have the same problem on my HTC Desire. Interesting to hear what the experts have to say.

Yeah these amoled screens are uber bright!

Download AdjBrightness from the market, it rules.

I have read on the net that it doesnt work for Galaxy S.

The app is called screen filter. Don't really know too much about it other than it works fantastically well and its free. Reduces brightness to almost nothing if you want, and the app functions as a widget for toggling as well.
I've been going around posting this in as many places as i can because this freaking app really helped me out, I could hardly look at the screen in the dark at all but now its good to go. Hopefully help some new galaxy purchasers out.

You can't go into minus values but you can set it to 0, which is 1 above the screen actually being off.
You need to be rooted, then you can just adjust the value with adb.

Brightness Bug?

Hi,
Have any of you noticed when you push the home or the power button to turn on your phone to unlock it the screen is really bright for a second then it switches to your settings? Has anyone experienced this and if so has anyone found a way to stop it?

Yes sand issue here had 4 of these things. Pretty crap really and the lowest settings is not low enough in a dark room.

I fixed mine. Turned off adaptive display and reset the handset. Problem solved.

Nu such issue on mine. Might be because of auto brightness, the sensor is off when the screen is off.

Yes. I have see this issue in my brother in law note 3. We all bought 3 note 3. 2 of it doesn't have this issue. I wonder is it hardware issue? Since the other two phone will never having the brightness problem.

I noticed this on my Nexus 7 2013, it's really annoying when you want to say read in bed and the lights are off it's far too bright. I found using the app Brightness Adjuster solved this. It lets you go way below the firmware level of brightness and I have found it excellent. May work on your NIII.

[Q] Way TOOO dim

I guess I should have done my research about OLED screens, but I feel that this screen is way too dim both indoors and outdoors. Is anyone else having problems with this? I know that the peak brightness is 475 on autobrightness, but I feel that the screen never reaches that. On another note, the colors seem very saturated and unreal even on movie mode...
Is there any way I can set the autobrightness to kick in at a higher lux indoors? I know it seems like I am venting, but I really like this phone but the display brightness may make me abandon for the Nexus 5...
Thank you everyone!

Root the phone and install a custom ROM. That will give you the ability to change the auto brightness levels easily.
You could also turn off auto brightness and set it manually so you fan boost it all the way up whenever you wanted.
As far as the hardware capabilities the screen is capable of being plenty bright. I could see mine if I was standing on the face of the sun.

I have rooted and installed a custom ROM (omega)...is there any way that I can do it on this rom or do I need cyanogenmod?

I don't know much about custom TW ROMs as I run aosp exclusively. I know its easy in cm ROMs. If its not a native feature of Omega I'm sure there is a mod you can tweak it with. You would have to search though. I don't know where to direct you.

Nexus 6P brightness mod

Gday guys just wondering if this phone will be capable of a extra brightness mod like the nexus 6 was. In sunlight this phone is difficult to read..

Yep.. It's nothing like the note 5 in sunlight

Yes please, even my old S5 is easier to see in direct sunlight.

Yeah it's not great at all in direct sunlight

Wow even if adaptive display on I do not have problems with the screen brightness in sunlight. Maybe I just don't use my phone is direct sunlight as often as I think but I never have to turn my brightness above 50%. I find 100% with adaptive brightness off to be way too bright.
I would not risk any mod to increase brightness it will probably destroy your screen.

I hope this will help ! https://m.reddit.com/r/Android/comments/3xexxo/nexus_6p_high_brightness_mode/

Hello everyone, please take a look at the Original Development thread. From the top of my head, Franco and ElementalX kernels have this capability, it works wonders in direct sunlight.

Confirming, kernels include this capability, as well as the ability to overclock or underclock other system specs (not required, but possible). Speaking for high brightness mode on Franco Kernel using Franco Kernel Updater, it's maybe 15% brighter. Noticeable, but not dramatic. With this combination (FK + FKU), you can't simply increase the maximum value of the brightness slider. Instead you can either turn it all the way on or off manually from within the app, or have it automated (you can't adjust the settings, e.g. how bright, what threshold it triggers at, and it's still all the way on or off with the automatic setting).
Can't speak for elementalx, but I hope someone delivers a more elegant solution. EDIT: having just watched a video about elementalx, turns out that kernel allows you to automate the trigger with tasker. Again, it's still either all the way on or all the way off. Judging by the video the brightness didn't appear to differ from franko kernel's high brightness mode.

It's the same on all kernels. I brought the feature to this device and also created a handy widget( check my sig). The beta version of the widget has an auto mode

Pixel shifting app

I was just wondering if there is a separate app that can do something similar to the "prevent burn-in by shifting pixels every..." In the smart pixel feature that I noticed in RR rom for the v20 that works regardless of what the user is doing. Maybe it could help get rid of this screen burn-in that some others and I experience?

Or you could try using a custom kernel that supports kcal and adjust the color settings to reduce ghosting and screen retention

Doesn't really work for me. I've lowered the rgb values down to 220 and although it's not as bad as higher values it's still visible when anything on the screen stays in one place for a while.
Maybe I'm just sensitive to it or something because I never had a device with an lcd that has this issue.

What percentage is your brightness on usually ?

It varies because I use lux but on average I'd estimate around 50-60%. I know the screen being brighter probably induces it more but it's easier on my eyes when in the little room that I use it in.

That is my theory. Brightness over 50% for extended periods causes this problem.
Indoors I have mine at 25%. No sign of any ghosting a year later and i should say the same with the G4 too.
I got used to lower brightness for battery reasons. My laptop is on zero and even that is just right indoors.
Outdoors is a different story.

1.flash kernel that support KCAL (im using M2000)
2.download Color Control app:
https://android-apk.org/re.codefi.savoca.kcal/
3. give root access if asked
4. set value as image attached.
5. wait for about 10-20mins (screen on)
6. youre good to go
* dont forget to set on boot color control
