[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.

[Q] Flashlight-App for dual-LED (ultra-bright mode!)

Hi there...
I am searching for hours now...
I want a Flashlight-App that uses the "ultra bright" mode..
all apps I found only were "medium bright"...
if you ever used a Flashlight-App on HD2 on Windows-Mobile, you should know, what I am talking about.
Only App I found was nexus-one-torch.
I think it "takes photos" to make the dual-LEDs go maximum brightness, but the disadvantage is: it flickeres alot..
Anyone knows a Flashlight-App that uses maximum brightness of the dual-LED-Flash on the HD2 with Android?
Thank you!!
Greetings from Germany!

I like Tesla led. it seems pretty good...

But Tesla LED is not as bright as Windows-Mobile or "Nexus One Torch".
It does not utilize the maximum led-brightness. :/

Why would you need the Max LED flashlight?
Are you gonna setup a party xD!
I think that.. its useless.. the "one" (referred to the settings/drivers) we got now is awesome.. i can clearly see everything in my room when the lights are off.

Because the device is capable of such a brightness..
aaaand...
BECAUSE ITS COOL!

and you risk damaging your led lights...

Uhm.. NO? Windows Mobile runs the maximum brightness with the standart HTC-Flashlight-App.. so definately: no!

You risk destroying the LED's, they will burn out.
It doesn't matter what your own personal experiences are, they will break. Think of it like staring into a laser and not seeing instant visual disruption. It'll happen, just give it time and it'll mess things up.

Everything breaks eventually my friend. I admit it may shorten the leds life span but some might not care because they wont use their phone for years and years. I personally have been using high mode on my nexus one for over a year and its still going

If you need something brighter than tesla, wouldn't it make sense to just use a maglite? Phones are great for minor conveniences, but just like the cameras, if i wanted top quality photos, i'd buy a digital camera not try to squeeze quality out of an inferior cel phone cam. Same with the flashlight, great if u drop ur keys at night, not so much if you're trying to light up your whole backyard or something.
-HD2 Android-

i dont think the torch app really uses the brightest setting.
i think its a matter of being properly programmed/optimized for hd2.

You could try Mag Flashlight, it has two brightness levels, but I'm not sure if it can use dual LED

yeah i remember the stock Hd2 flashight was WAY brighter, it puts the ones on android to shame, i want it back!

Yes, I've downloaded all available flashlight apps on the android market for my htc hd2, and NONE of them have matched to the htc hd2's windows mobile version. That particular version had 3 settings, low medium and high. All of the android flashlight apps seem to match the MEDIUM setting that the windowsmobile version was able to output.
Can someone port or write an android app that's nearly identical to the stock htc hd2's flashlight app that had 3 settings, without the annoying 5 second demo animation at the beginning on how to use it? That third setting (high) was KILLER, and impressed all of my friends as to the htc hd2's dual led true potential!

Same here, anyone have found any program with full bright?

HERE IT IS! (well i think its it. IDK)
okay so i pulled this off my typhoon CM7. its the "Torch" app. it has a high brightness setting as well as a strobe feature. (i have my mini raves XD)
its in apk format.
put it in sdcard, use a file explorer to locate it and install it. it should work.
btw i forgot. if it works hit the thanks button have a good day.

Unfortunately, like everyone is saying even the one that you pulled from the typhoon (althought it says it is the highest possible setting) is not the brightest setting that WM was able to achieve. Anyone else still looking for this like me? If someone who knows what they are doing could do this, it would be awesome!
For those that don't understand why we want this, you haven't used the WM LED flashlight long enought. I actually have great stories that goes along with the brightness of HD2 flashlight in WM (from everyone envying me at concerts to saving a bunch of us in the middle of the woods after the sun went down in the middle of a hike that went wrong =P).

[DISCUSS] Screen brightness sensor a joke!!

Sending this straight back, I cannot believe there is no option to disable auto brightness settings on this heap of ++++.
It has got a mind of its own and is extremely annoying to suddenly see the screen get dim and bright every 5 seconds without any change in actual lighting condition...it makes the phone almost unusable.
Hope someone can make a hack for this soon.

Yes, totally a reason to send it back, software bug on a phone with a unlockable bootloader. Hope your next one doesn't have any real issues

Maybe this was the software bug vodafone was saying?

http://www.google.com/search?client...rceid=opera&ie=utf-8&oe=utf-8&channel=suggest
sure you can't find a solution? It must be somewhere in the settings (I'm no android expert though).

It's not a "software bug", it's SE dictating to us that in order for the paltry battery to last a day, we need to use it in the dark, or disco mode!

... unless the sensor it's self is dicked, then it can be fixed in software, even if it is dicked, it can be completely disabled.... just cool your jets.

well i report no such shinanigans happening on my phone! i can see the light sensor in action when i cover it with my thumb, it works really well and the gradient of fading and lighting up is the best i've seen on any phone so far! i dont notice it when using it normally.
you must have a faulty one....

They have to stop the complaints some how, at least the speakers are not gimped

Thought I'd mention that I have no such problem with my device.

I'm very happy with the screen. Especially good as I moved from a nexus one.

Can't you install brightness level from the market to controll the auto brightness ?

Wanna control your brightness levels quick and easy? I use a very slick widget called Dazzle. It has every option you can think of to control just about everything on your phone. Give it a try.

I don't seem to have auto-brightness, do have a slide in the settings to ste brightness though, on highest I can easely see in the sun and it hurts in the dark, on the lowest settings it's hard to read at night.
A Dutch review actually mentioned a lack of auto-brightness as one of the downsides to this device.

It does have Auto Brightness as if you put a finger over the light sensor the phone screens dim.
The phone had an update pending the day I purchased it so most of the reviews I have seen are out of date. This phone is excellent at playing games.

I hear that. In love with my Xperia Play.

Guys can someone tell me. A lot of reviews say that the screen is very dim even on max setting and a lot of reviews say the exact opposite. So what is it?

Mine is perfect in the sun. I'm starting to think there are 2 types of screens involved, anyway to check what screen you have without opening the device up?

Screen brightness is ok for me, but just remarked the display have some ghosting issues. Slide beetween programs screens and observe carrefully the icons.... with red "Adresse" one this is very visible. i can't belive sony use a high response time display on a gamer device.

note 3 screen auto dimming

adaptive display off
reading mode off
brightness manual
smart screen off
brightness level set to 90% or so
and my screen auto dimm for no reason playing PVZ or any other game is very annoying to the point of stop playing
I did some reading on att note 3 forums and they said this is implemented on the Kernel itself so if we can get full unlock perhaps we can use a custom kerlel to fix this BIG PROBLEM

Ahh, gotcha.
I've never experienced any problems with the screen dimming when I'm using it (even playing games). But I like to use Smart Stay (works great for me) and I like my brightness at 100% all the time, so it's a little different scenario, I guess.

I've seen it and been looking for where to turn it off. Was going to post about it, so glad you did. It's very annoying and send to happen at odd times in pretty much any app.
Now here's another one for you. Have you noticed when you pick up your phone that it will vibrate twice? I can't tell what I'd doing it, so it may be a system thing.

Yea if in the next update it don't get a fix Samsung will not like me very much
Like how LG probably hates me every chance I get I talk **** especially about their LowGrade ****uition
Android product ...LG is byfar the worst android creators out there and should just stick
To making ****ty appliance or better yet just stay out of the electronic world all 2gthr IMO...
But back to the subject at hand it seems its when a lot of processes are going that it dims (CRASHES)
Try keeping an auto task killer app running to kill unwanted tasks as they pop up...
It works but not for too long. it would seem the 2G of RAM is not enough for the quadcore
maybe 3G would have worked better.

Solution
Kinda late with an answer but I figured out why my note 4 was doing that out of the bloom. Turns out I had an option checked for my screen brightness to adjust based on the image that was on my display. Just go to Settings, Display, then uncheck the Auto Adjust Screen Tone. That should fix it. ☺

Screen too bright even on lowest brightness

Hello, I have recently purchased Moto G4 Play and I find the display of it too bright even on the lowest settings.
I used to read news and ebooks at bedtime but it is very stressful with this level of brightness.
I have tried 'Screen Filter' app and it slows down the mobile plus the actual brightness is not reduced.
I will root my device if it is going to help me with this brightness issue.
What would you recommend? My device is still in the 10 day window for return from Amazon.
Thanks.

Not sure about stock but the brightness goes pretty low on the XOSP rom I'm using right now.
Because you mentioned you use it for reading, I would recommend Twilight or f.lux(both available on playstore f.lux needing root).
They really help with the screen saturation and make it easier on your eyes.
I tried screen filter and it worked perfectly. Maybe it has something to do with the stock rom.
An alternate to screen filter would be Lux Lite it worked as good as screen filter maybe this works in your case.

Thanks for quick reply

I am already using Twilight : ), I am little scared about rooting this brand new mobile due to warranty issues. Just for comparison,
the lowest brightness on Moto G4 Play is like Middle for Moto G3 / E3.
Can I claim warranty after rooting this device?

It says on the bootloader unlock page that you cannot once the bootloader is unlocked. So you can't claim the warranty after rooting. But mostly they don't bother letting you claim it on some hardware problems but you should still think of it as void and not take any chances.

Twilight Pro is much enhanced that the free version. I'm using it since I bought this phone. It has "Bed Reading" profile which helps you read in the dark without letting you put stress on your eyes and help you sleep as soon as you leave your phone. According to me, just leave it on default settings and switch to Bed reading at night.

Hi, thanks for reply! I've got 'Bed Reading' profile option too but I am using the twilight free version. Anyway, buying it for sure since it certainly helps me and so should the dev get helped.
I have no compelling reason to root this device except this brightness issue, and I am little worried about Nougat update too, feeling maybe Lenovo will roll back its promise.

When I downloaded it first, it asked me to buy for just ₹20 ($0.29) and there was no reason for denial

What about the adaptive brightness?
I had adaptive brightness set to true when I was facing such a problem. Now it works fine. You can check the Ambient Light sensor in GPS Status and Toolbox app.

Screen filter puts an overlay over everything else, the backlight is still the same it just looks a little dimmer cause everything is a little greyer.
Xposed can lower the backlight

Great find. Now the brightness is perfect for night reading, and it will also improve battery life.
I don't understand though why manufacturers limit the min brightness when it's "free", maybe to artificially segment the market (flagships always have excellent low brightness)... There are cheap chinese phones that have hardware backlight limits, but for G4 Play it's definitely not the case, it's just software limited.

GravityBox (xposed) can dim the "real" brigthness too...
Note that if the lcd brigthness set to minimum (GravityBox or AllMy....), Youtube videos cant be played in full screen.

- Using GravityBox or AllMy..., ser the minimun brightness to 1 (or even 2)
- Without adaptative brightness, set the brightness (slider) to minimum
- Go to Youtube, play a video and expand it to fullscreen
The screen becames totally black, but the video still playing (the audio still playing).
Note that if the brightness slider isn't at the true real minimun, everything works nicely.

I tried exactly that, but it works for me. I also use Youtube background playback Xposed module.
