ScreenDim or RootDim - Acer Iconia A500

This was posted over in the A100 forum.
A couple of apps to dim your screen past default. Easier on the eyes when reading in a low-lit room.
ScreenDim is a paid app.
RootDim is free but must have root.
If you lower your brightness too much and cant get back easily, just reboot.

I tried both of these apps, and i was comparing them when i discovered that you can use both apps simultaneously to reach ultra-low screen brightness. I don't know why you would want to go that dim, but try it out it might be useful if you find yourself lost and stranded in the middle of nowhere at night with no phone charger and a low battery

Kernel makers, please add the ability to adjust auto brightness.

Please add the option of modifying auto-brightness levels, like CM 6.1. I suppose that it would require a kernel modification + an app to do this through gui.
Thanks.
What can CM do? I've been thinking it would be nice to be able to modify the min and max, and maybe the curve.

It allows one to arbitrarily edit a table of sensor output vs brightness/button brightness.
It's really nifty.
CM6.1 reports these sensor values:
10, 160, 225, 320, 640, 1280, 2600, 10240
10-160 is in dimly lit indoors, 320-640-1280, in moderately to brightly lit indoors, and the rest is outside.
So I set those to brightness something like 50,60,70,80, 110, 140, 180, 255. A it was perfect to my eye. Not too bright, not too dim.
Didn't ever have to mess with brightness after that.
I'd really like to hear from developers like Netarchy and King, as well as from regular users - if they would like that option.
I would love to see this.
I always feel the auto-sensor tends to be too bright, and never adjusts the screen low enough inside.

That's exactly what I think. Plus, the brightness is not at maximum in direct sunlight (although that might be a safety feature).
Mine always send to bright, or it won't get bright when I go into a bright area until I sleep and wake it. :|

The stock auto-brightness is way too bright in completely darkness. This is one of the things I had on my list nearly since the beginning. Nobody else seemed to care.

An article showing how useless auto-brightness is:

Do people not notice this or do they just not care?
Pretty sure people have given up on this. It's taken me three days of Google searching to find this thread so people probably don't know where to turn.
The lack of adjustments to the auto brightness values is extremely annoying. Even my old Windows mobile 6 phones had this ability.

There was an application for WM I used to use on my Mogul, cant remember what it was called but it allowed you to calibrate the auto brightness levels. Anyone know what I'm talking about, or if there's an Android version?
This can be done with Tasker in the Market. Its a powerful app and there was a thread a while back about this exact thing. I don't remember what it was called, but I posted in it, so you could browse my posts from a month or so ago.
Hey... This thing makes phone calls too!

[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!

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....

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.

Lower minimum brightness

I like to read at night in dark room, and I find that even on lowest brightness screen is to bright.
I am stock rooted and unlocked, I tried adjbrightness (I use it on my gNex) but it must not be supporting Jelly Bean yet.
Any thoughts? I miss Adjbrightness

I use ScreenDim on a Galaxy Tab 7 Plus and on a Kindle Fire, and it works very well. My Nexus 7 doesn't arrive til later today, so I can't guarantee it will work, but the developer says it works on Jellybean. I like the fact that this app has presets which allow you to easily vary brightness and contrast as lighting conditions change. There is a trial version available. In summation, I recommend this app!
ETA: This app makes it possible to lower brightness below what the device would normally allow, by combining the brightness and contrast adjustments.

That will only make the colors/whites darker since it just draws a semitransparent black "sheet" on top of everything.The backlight will be just as strong.
Edit: sorry maybe screen dim does adjust the backlight... maybe I'm thinking of a different app.
OP, you could try rootdim from the play store, as it uses root to lower the backlight more. Not sure if it works wit the 7.
Or changes can be done in the kernel source.

This app has two modes, one which lowers actual brightness, and one which adds a the semitransparent overlay you mention. You can use either or combine them to achieve lower light levels. IIRC, according to the developer, the one which lowers brightness saves battery, while the 'gray sheet' mode does not.
Anyway, since there is a trial version available the op could see if it works.
Previously, I tried another app which only had the semitransparent overlay, and did not find it as effective.
I had the same issue. I've used Screen Filter previously. Now I'm using Elixer 2 screen filter toggle on a widget. Both work great and are free.
Check out RootDim. I'm not sure it's compatible with JB yet since I'm without an N7 for now, but if so, give it a shot. I tried it on my Bionic and it did the job nicely. I eventually uninstalled it because it messed with the capacitive button backlights, but obviously that's not an issue for the N7.

[Q] Galaxy S4 Screen dimming.

I got my Galaxy S4 yesterday and noticed even after i turned auto brightness off, Set my screen to dynamic, the screen still changes brightness levels when entering the Chrome web browser (gets dimmer), playing some video games (screen get brighter) and other various tasks.
I am not a noob, I've gone through the phones settings for each app and cannot find a fix, do you guys notice your phones doing the same thing?? I might be a slight change in brightness level but non the less i like my screen extremely bright this is just my preference.
Any thoughts, ideas, tweaks or feedback on how to resolve this issue??

The only time I've seen this happen since I've gotten the device is when the battery dropped below 5%, and it automatically adjusted the brightness to seemingly the lowest it could go, and stuck until I charged it to full again.
I blame it on Samsung's stockware.
maybe this is why i couldnt get the phone to look as bright as my note 2. i was using the browser and cnn.com to compare.. my note 2 screen was brighter with both phones brightness on max.

Just throwing this out there...the screen does dim about 10 seconds before the screen times out and turns off...even if you have automatic brightness disabled.
Let's say you have a 1 minute timeout:
Screen on
50 seconds later screen dims
10 seconds later screen turns off
Just putting that out there in case - it is confusing to some.
Dude I'm having the same problem, yeah it's a small dim but it's freaking annoying cuz I have mine at full brightness all the time. I have the tmobile galaxy s4. I tried changing the screen mode and it still happens

I've noticed it too. Just seems like typical dynamic contrast behavior. Though I don't understand why on earth you'd need it on a screen with perfect blacks.

I'm sure it has to do with preventing burn in. You probably already know this, but in the right conditions, the Auto brightness setting can get over 30% brighter than manually maxing the slider. Hopefully, it's something that can be unlocked at some point.

Its the power saving option. Its the same in s3. Go to powrr saving settjngs and uncheck the auto dim or auto brightness or something like that. It happens when power saving is on. I cant remember the exact optin coz im using custom rom on my s3.

This happened in the S4s I used in the store as well. Manual brightness, and auto screen adjust disabled, power save off. Opening certain apps like chrome and the stock browser causes the screen to dim a bit. Nothing I found prevented this behavior. It's annoying since I already find the screen to be a bit dim.
Sent from my SAMSUNG-SGH-I317 using Tapatalk 2
Notice this as well, super annoying. I've disabled power saving, auto screen adjust, etc. and even non-dynamic modes do it.
Hopefully this gets fixed by kernel mods in the future
Same problem, even with brightness max with auto off, decent charge, and off power saver. Very annoying

Its built into the Snapdragon, its called BRITE and seems works independantly of the auto screen tuning that the S4 has. The HTC One has it and its much more intrusive. I wrote a long winded post about it in the HTC One forums. You have to wait for devs to come out with kernels to disable it, much like they did for the Tegra 3
The HTC screen is bright enough that it doesn't matter. Samsung phones need to be at max brightness to be any good.

Just an FYI, if you put the screen on auto brightness, it reaches a higher maximum brightness outdoors as apposed to the slider. Samsung did this to keep the screen from overheating when set to max all the time.
I want full brightness indoors too.

I see. If you have the slider on max all the time, i think the screen will just dim eventually because of heat. Might want to stay away from the S4 then cus you might have screen problems down the line :/
If you havent go to settings display screen mode and use something other than adapt display. No more adjusting.

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.

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.

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.

- 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.
