ScreenDim 1.10 beta -- need testers

I apologize if this violates forum rules.
ScreenDim is my (paid) app for dimming the screen beyond standard OS settings. On OLED devices, it basically does what ScreenFilter does, but I think in a rather more friendly and useful manner, including pre-sets. (On LCD devices, it's much better than ScreenFilter, as it actually dims the backlight, thereby improving contrast and battery life.)
I just finished making a beta of ScreenDim 1.10. The main new feature is Easy Mode which combines the brightness and contrast sliders into one. Currently, Easy Mode only works on Galaxy S2 (including Epic 4G Touch and other versions) and Kindle Fire. You can toggle Easy Mode with Menu | Settings | Easy Mode.
I'd be grateful for any beta test results. To the first ten people who send me useful reports, I'll give give free copies of the paid ScreenDim 1.10 once it's released, as well as free copies of my LunarMap HD and Force2SD apps, if you want them. (Alas, I don't have a gift-code setup arranged, so the free copies won't auto-upgrade.)

I would be more than happy to be your first beta tester!

Buggy at times, when at 0% it doesn't work with volume keys --- only min: 0.0% and Max 0.1% when put down to 0.0% with volume keys...
Same applies when pressing min (highest will go to 0.1% when holding volume up and repeatedly hitting volume up...)
When screen is too low a dialogue should pop up saying if you do not confirm this brightness within 15 seconds, it will go back to your last setting...
There should be an option to disable notification icon (not invisible, just not at all) totally when using and/or not using the application.
A more detailed About/Help menu would be more useful...

If I've helped, I am interested in free paid versions of your apps... I believe that if you send a check in the mail after the person buys the app as reimbursement would be more easier than consistently updating via email. (Not to overstep you or anything, just a suggestion.)

App works as promised. Some screenshots attached.
Suggestions: have way to disable notification icon.
Also when not in easy mode the lowest you can go is 11.8 on both sliders. Not sure if that is design or a bug.

Looks good, except the plus button above the brightness slider doesn't work. I'll play with it tonight and let you know how it goes.

Nice app! Everything seems to be working, I just don't understand the "Active" action..I'm not sure what the purpose of it is.

Great idea. I can send a paypal payment. I had someone do that for me when I tested their app, and I forgot that I could do it myself.

When did you download? I think I fixed that problem around midnight last night and uploaded a version with that fixed. (But I forgot to mark a version number.)

You mean the "Active" checkbox? That turns ScreenDim on and off.

Can't be done without sacrificing reliability. Unless you do something root-ish (and I really want this app to be non-root), the only way I know of keeping an app from being killed in low-memory situations is by using Service.startForeground(), but the OS requires a notification icon when you do that.
Also when not in easy mode the lowest you can go is 11.8 on both sliders. Not sure if that is design or a bug.

If you want, you can make the brightness slider go down to 0.4% by using the "Set minimum brightness" menu option. But you will find that below 11.8%, the brightness stops changing, so there is no point to that, and that's why I set the default minimum for the Galaxy S2 series to 11.8%.
You could make contrast go below 11.8%, but the display would probably be dimmer than anybody wants (I am about the pickiest user in terms of darkness, because I am an amateur astronomer, and I don't want the device to destroy night vision), and the display quality would be low. Unfortunately, given how OLED devices work, at low brightness levels there are much fewer colors available.
Technical stuff in case anybody is curious:
The way Easy Mode works is that 30% on the Easy Mode slider is equivalent to 11.8% on the brightness slider and 100% on the contrast slider. When you go above 30% in Easy Mode, you're increasing brightness and keeping contrast at 100%. When you go below 30% in Easy Mode, brightness stays at 11.8%, and contrast goes down, hitting 11.8% when the Easy Mode slider is at 0%.
On LCD devices, the brightness slider controls the backlight and the contrast slider controls the white level (by drawing a gray rectangle over the screen). On OLED devices, both of them have a similar visual effect, namely they both reduce the intensity of the miniature LEDs that make up an OLED display. But at low brightness levels, you have fewer color intensities available on the physical display.

Works great. I have been waiting for this so I don't have hear the wife complain that my screen is too bright at night and keeping her up.

everything works really well, tested in easy mode... only issue was the " + " button didn't work the first time I pressed it, and the n I pressed " - " and they both started working again. I could not get the issue to happen again, don't know why it happened the first time.

works as expected. only problem, and perhaps this is intentional, is that if you change the brightness in the android display settings (as oppoposed to the app), then it goes back to the standard android brightness scheme. in other words, the app and android settings dont seem to correlate with eachother? lemee try to give you an example...
i go into android display settings and change it to 100%. then i go into your app and set the brightness to 0%. this dims the screen down tremendously, which is exactly what i like. okay, now if i go back into android display settings (still leaving the app still at 0% with ultra dim display), and lower the android screen brightness setting to say... 95%, the app seems to disable or something and the brightness will jump UP to android's 90%. instead of the display getting further dimmer, it instead shoots back up to almost full brightness when it should be going down. i hope that makes sense.

Right, the system settings partly override ScreenDim's brightness setting. I can't lock in the settings without root.

this app rocks man, thx

I found a bunch of bugs when using "Quick activate" and loading presets and changing settings starting from a disabled state. I fixed the ones I found in 1.10c (now up), but there may be others.

Screen brightness messed up in P beta 2(dp3)?

I upgraded my phone from 8.1 to 9.0 yesterday and noticed that my brightness slider is now much higher up to 100% than it used to be. I have to make it go much higher to get bthe same brightness. Going to my old brightness setting makes the screen really dim. Is this a bug?

What does this mean though? Because now it's really dark until you get to over half of the bar then it shoots up quickly. Doesn't make much sense to me. I'm not using auto brightness btw.

Something to do with the non-linear (logarithmic) scale being closer to real world physics or something like that, not exactly sure why it should matter, but Google and others have decided so. It just means that the "graph" of the scale is not a straight line but a curve.

Brightness was fine before the June update. After the June update I have to set it to 83% brightness to get what I was getting at 50% brightness. It's a bug. I flashed back to 8.1 for now.

MIUI Auto Brightness Fix (Magisk Mod)

Do you have problems with auto brightness in MIUI roms? Your screen brightness gets extremely dark in low light conditions, or the brightness spikes just with a few increase of light?
For low brightness problem, actually you can adjust the minimum autobrightness in slider bar, but sometimes it will reset back to default minimum brightness. For example if you turn off auto brightness in game, when you turn it on again, it won't resume your settings. As a result the screen will get darker than your adjustment.
I created magisk module to fix that. This will increase the minimum brightness in low light, and also reduce the over brightness in medium and high ambient light. The result will be smoother auto brightness step, and be more convenient for your eyes!
There are two modules, one for Miui 10 running Android Pie, and the other ones for Miui 10 running Android Oreo. Dont install wrong module, because there are much more brightness values in Android P than O.
The Oreo version may be not as good as Pie version, because i tested it in Redmi Note 5. My Mi Mix 2s currently running Miui 10 P beta 8.8.16 for Pie version testing. But it should give the same result. Oreo version works in Miui 9 too, but may results different.
So what this module do? It adds framework-res to the /system/media/theme/default. With a magisk module you can do it systemlessly! To install it, just download the module then browse it in Magisk Manager.
If you dont like my setting values, just unzip my module, find framework-res file, unzip it, then edit the theme_values.xml to any values you want under "config_autoBrightnessLcdBacklightValues", then zip all back.
Download links in attachment.
Guide:
V1 for lowest brightness (best battery)
V2 for a bit brighter in low light
V3 for brighter brightness (best for full edge cover tempered glass user)
V4 for more responsive and smoother auto brightness. Values are about similar to v3.
To check if this module works;
Tap the Kernel Version in About Phone 5 times, then you will enter CIT. Go to Light Sensor. Cover your phone light sensor on upper bezel (lower for Mi Mix 2s) with your palm till the light sensor value reach 0. If the backlight is not going under 100/130 (pie) or 7 (oreo), then this module works! My module limits the minimal auto brightness, which the original can reach to 20 which is ridiculously very dark.
This module may work on any MIUI-based rom phones with IPS display, not just Mi Mix 2s.
I also created this module for Mi 9 (amoled display). Visit my thread HERE
Notes:
- Only V4 has responsitivity adjustment. More responsive means it needs less light increments to trigger auto brightness adjustment.
- Editing the values can cause a mess. Add .disable_magisk file in cache partition if your phone cant boot then uninstall the module in manager.

Thanks have flashed this and will see how it goes over a day/night. Initially it's good though.
I find the auto bright annoying sometimes especially given how easy it is to cover the bottom chin sensors on this phone.

Thanks for trying. I hope you get better auto brightness experience after a day..
Yeah the worst part is the light sensor in mix 2s located in bottom left where you could get the screen unseenable while using two/left hands. If its in center, it would be better.
My other mi phone with forehead light sensor often gets annoyingly too dark. I never satisfied with miui default auto brightness and always use this mod since miui 7. Fortunately, this method still works with some adjustment in value.

Ok so it's been a couple of days and this has helped a lot imo at least for indoors (haven't really had any major outdoors time...).
Still gets dark enough when it's really dark, but certainly for normal indoor conditions the default settings you have are much better. Xiaomi settings often got too dark, and you can adjust the slider, but then the slider goes back after while anyway :-\

Just reporting back after a while with this and more miui updates, seems the later beta builds have changed something in the brightness in that I don't know if this mod works any more, or if it needs tweaking to provide the same brightness levels it used to.
I had a really quick play with values as suggested in the op but it's well outside my field of expertise and couldnt get it to do much different

@arddy1
... where to find the default values ?
I'm on Poco F1 and want to compare to the default values and adjust theme_values.xml

Sorry for late reply. This mod still works in miui 8.10.11 global. Here are the screenshots of screen light value in lowest brightness. The lower one is the original. Mine still brighter in lowest light.

So it only works on miui

Yes since it's a miui issue. Stock android roms don't reset brightness like miui.
Stock roms just set the brightness bar where you want, some will have the ability adjust the total curve even. Miui if you raise brightness it will change itself back after 5 mins or so, so it's needed to change the system default values

Auto Color and Sharpness based on enrivonment luminosity

So, I noticed the screen changes its colors and text sharpness based on the environment clarity. Altough this seems a nice feature for using the phone on sunny days, the effect brings a strange oversharpened effect on the screen text. Not really a big deal, but I don't like it much.
Is there a way we can disable this feature? I've already tried going into "Settings > Display > Contrast & colors" and changing to "Standard", which should keep the contrast constant, but it seems the option isn't really working. I've restarted the phone and it keeps changing the colors and sharpness.
I made a video for you to understand what I'm talking about.
https://www.youtube.com/watch?v=_jXgLy7Bn5k

Thats samsung super amoled boosting brightness nits to increase readability,and its normal, it does happen in all super amoled screens including samsung note 8 and etc.
So it cannot be disabled as far as i know its in firmware of display.
But when you are in direct sunlight i think sharpness or color dissortion is not much of a sacrifice to increase readability.
Would it be better if you wouldnt be able to read whats on display ? dont think so.

For a second i thought my display was faulty but then realized its only for better readability. Not that I particularly like this but the sacrifice is worth it. For now haven't seen a toggle for it yet, but I hope xiaomi gives it in the next update.

Are you sure it is a feature of the display itself? Cause the brightness remain constant, what changes are the colors (contrast actually) and the sharpness...
And yea, like I said, it isn't a big of an issue, I just wanted to have control over it, but I can live with it haha.

I had this on my Galaxy S9+ and somewhat annoying under sunlight, though not as noticeable as on Mi 9 SE because of higher resolution and DPI. The only way to deal with it on my S9+ is turn off auto brightness and slide the brightness down to a manageable/readeable level.

Brightness on Android Q

Hi!
Does anyone know if brightness settings will change on Android Q? For me, they were ok on Android Oreo. I know that the 2 xl hasn't a superb display, but Pie did a total mess!
I wish I could set the brightness at 45 - 50% as I did before (the screen didn't suck) instead of reaching the 90%! I haven't installed any Q Beta version yet.
Thanks in advance

The Pie brightness was overhauled and had different locations for the same brightness compared to Oreo. But in my opinion auto brightness on pie and Q is much better than Oreo. You can also train it to adjust to your liking.

Thanks for your answer

Starting with Pie, they made the brightness slider linear. So 50% before Pie was definitely not 50% nits output for the screen which, with a rated max 403 by anandtech, would be only 201.5 nits. And that was before the November update that lowered the max by 50 nits. That's why you're needing it to be 90% and higher in bright ambient light.
