[Q] Reduce screen brightness? - HTC EVO 3D

Hey everyone-
I'm looking for a way to reduce my backlight brightness further than the normal levels. I use my Evo as a night clock, but the minimum brightness still beacons a bit in a dark room. I believe this is possible, but I'm not sure what I'm missing. I tried out an app called RootDim from the market. It lets you move the slider from 0 - 255. The screen gets darker as you slide it backwards, but it stops dimming when you hit 30. Anything below that does nothing. I thought it might be a kernel issue, so I flashed the nolights kernel to test, but that didn't change anything.
I am also aware of screen filter, but that doesn't actually dim the backlight. Anyone out there no of a way to drop the minimum backlight level below 30?
EDIT: I should also mention that I'm using Android Revolution as my ROM. Thanks.

Been looking for the same thing as well. I was hoping RootDim would help , but I got the same results.

Have you tried DOCK mode ? It's a built in APP on HTC EVO 3D.
Do a Search for DOCK and try it. It runs in Lanscape mode and it
switches to a night mode after a few minutes or you can switch
manually via the lower right lower corner.

I tried that already. And I'm using Dock Mode. The problem is that even at minimum brightness, black color still lights up the room a bit. Considering that it stops dimming at < 30, I'm assuming there must be some way to get levels between 0 and 30 as well. I guess it stops at 30 as a safety net, to keep you from dimming it so much that you can't see the screen.

Bumping this. I feel like cyanogen let me go darker but I'm back on sense and am looking for a solution.

I use the Android Assistant app, free at Google Play. It will let me take the brightness down to 11. Not sure if this would be low enough for you. The control is in Tools, Save Battery.

Any update on this? Whenever I'm in a dark room my lowest brightness still seems too bright. Is there any way to get it darker?

Auto brightness

Does anyone have a solution to auto brightness issue?
Even in the darkest room, the lowest light level is "medium" and not low! Its excellent setting when using phone outdoors but in dark room or at night its just too bright. Is my phone broken or is it general windows phone setting?

on my titan, the auto brightness behaviour is erratic and sometimes goes too low.
the camera is one of the issue triggers. after every return from a photo session, the screen goes to a lower brightness.
also, sometimes it happens when unlocking the phone but i don't know what triggers it. then suddenly the screen would return to its normal brightness after a few seconds, although not always.
i suppose it's a driver issue...

so you get the autobrightness to go as low as 'low' set manually? - I tried it but even after camera the lowest brightness I am getting is same as 'medium' when set manually!

no, not that low only lower.
but you are right, even in complete darkness the screen won't go to its lowest setting...
Yes same issue here.
Automatic can go a little bit lower than medium, but not much. Too bright in dim environement.
For general use, i would like to have a preset between low and medium
Since these days many people like ultra bright screens (and ultra loud sound) i am not sure HTC will try to fix this "issue".
I just hope Microsoft can add a brightness slider in the future. (Or bility to set the min auto and max auto levels)
Btw, do you know why camera mode go into max brightness ? This is a little harsh indoor.

Yes that behaviour is very strange too! I think it's present only in the Titan. Some other windows phone manage the camera brightness a little better. But then I think increased brightness while using camera sort of makes it little pleasant when using it outdoors. But indoors as you mentioned, it's a bit too harsh brightness!
I think it's the light sensor that doesn't work properly. Some places/forums mentioned about issues with various HTC driverseven after those 2 softwares updates we received in Nov-early Dec.
In daylight,the auto brightness works wonderfully for me,I never change it.
But in a fairly dark room,it's too bright and most of the time,I set it to low
I usually set it to medium... and set to low by myself by night.
I have sent a message to HTC (via theirs contact/ticket system) about the "can be improved" auto brightness, and "camera set brightness to max" issues.
Better than nothing.
Since this is a easily reproductible problem, maybe they can take a look if they receive several messages about this.
I wonder if the screen going to max brightness with camera may have something to do with the "HTC Camera modes" addon ? (who knows..)
But i don't see how to remove it. I even can't find it on the marketplace (under HTC section).
I have same issue, I get blinded when I check the time on my phone at night
It was there even before camera modes update was applied by HTC. So unlikely

Obviously, the brightness go to max too when using skype with video.
Hope they will notice and fix it.
Trying to talk to HTC customer service is especially unhelpful here in france.
They have absolutely no knowledge of theirs WP7 products
(whatever the problem encountered)
Now that we have unlocked roms, any way to tweak the auto brightness ?

I've tried all 4 ROMs and they have the same behaviour as stock ROM at the moment. But it might be useful looking into the registry threshold values. I know there is some sort of home brew app that lets us set the volume increase in 10s, 20s, 30s or 50s. So a regedit might be somewhere, will dig around myself since you've reminded me again

[Q] Brightness changing while watching youtube?

Hey guys I have a quick question. I was watching a youtube video in my room last night in complete darkness on the lowest brightness setting and I noticed the brightness would change slightly at random. I also noticed it on the skyrim live wallpaper and also while scrolling thru the marketplace. It appeared that when there were more white pixels on the screen then the screen would get slightly brighter. This doesnt happen in netflix or movies that i put on there so I'm hoping this is a software bug happening in google apps. Autobrightness is not on and i tried all the power modes with the same response. Anyone else notice this or also able to replicate this? Thanks!
hey dude!
I have the same issue! I think it is on purpouse. Some kind a way to save power? Here is my thread about this. Try my country and please give me some feedback. Most of users dont notice this. Maybe because their eyes are not so sensitive?
Oh and also if you switch to power saving mode the brightness change will much more significant than on the other two modes
http://forum.xda-developers.com/showthread.php?t=1419583
Really no one of you have this issue?
Sounds like a possible LCD screen flickering problem. It's a problem a lot of LCD display mobile devices have. My HTC Sensation has it.
Here's how to test it: at night, turn off all the lights in your home. Basically, your test area needs to be as dark as possible. Set your Prime to a set brightness, preferably as low as it can go. Open up something that has a uniform color and general brightness throughout, XDA app works perfectly. Go near a wall and point the display at the wall. Start scrolling back and forth through the app.
If your device has screen flickering, you should notice that the light on the wall rapidly fluctuates whenever you scroll.
will try. but i wonder if this is relatd to tegra 3 power saving system? i notice the brightness / contrast automaticly change while watching movies, surfing web and gaming despite off turning off autobrightness
so the question is. is my prime damaged or this is normal? dear xda users please how does your prime behaves?
It could also be a "feature" called dynamic contrast which is an idiotic way of making LCDs look like they have more contrast than they really have. But I hope it isn't, I despise it. Dynamic contrast works like that: during bright scene it brightens the screen, and during dark scene it darkens the screen. It's really annoying (and shouldn't be on ever apart from maybe when watching movies).
ok but the question is. how many of you noticed this issue?

I think everyone.
For youtube don't use eco. It's to aggressive and outside of normal videos apps like diceplayer it is useless.
I hope nVidia and Asus will decrease it or give us the option to disable it. Because i like the eco mode for watching flash videos. Much better than Balance and Normal because it's enough and i can save battery.

No, it's not for contrast. It's for saving energy by decrease the screen brightness and increase the color level. And it's always doing it. What we see are the problem of the technique.
Well if it is on purpose then it is very annoying. The only thing that helps a bit is to make screen brighter.
I hope it is not a defect of the screen.
Was looking for a thread with this issue, I'm also experiencing this effect.
It's also noticeable with the stock browser, seems some powersaving technique. Hopefully they will optimise it in ics or make it an option.
this DIDIM technology is constantly at work on our device. I saw a Ram dump txt(which I don't know where it came from) in ly Astro explorer. I looked at it and seen that DIDIM feature is constantly working and adjusting.

You guys know that it's not the power setting right? It's in the screen setting under brightness. If you set it to auto, it will adjust depending on your light source, if it's all white, it will be bright in a dark room and will adjust itself. Turn it off, adjust manually.
And you know, its not. It sets brightness high of overall picture is bright and dark if picture is dark... Much like dynamic contrast. It has nothing to do with auto brighteness. I tried that first.
But can I believe it was fixed in some update, since no one continues this thread after ICS? I cannot update becouse of unknow SN bug. Waiting for Asus to say either send it back or release fix. Thanks.
Happening to me right now with ICS, in performance mode, docked with charger in.
I've been noticing subtle changes in brightness no matter what performance mode I'm in, and I always have auto-brightness off. I normally keep the device in Balanced mode. It's most noticeable if I'm watching videos before bed, as I have the device brightness near minimum, and any change in brightness is pretty clear. At first I thought it was something to do with BS Player, but I've been using Dice as well and see the same effect. It may be a little better on ICS than it was with Honeycomb, but it's hard to tell.
If this is DIDIM, then I guess there's not much I can do about it besides hoping nVidia/Asus tunes the effect to be a little more subtle. :-/
I notice it, however it only affects me with low brightness/auto brightness setting. It does NOT kick in for me over 15/20% brightness combined w/ balanced/normal mode.
That is still on HC, wont get ICS update until two weeks.
Can also be noticed when canging homescreen tabs, slide it over slowly with your finger on the display (keeping it from flipping), once moved more than 30%, the display dims.
I am experiencing this brightness fluctuation, in all power modes, with auto brightness turned on or off.
Very annoying.

Thing that annoys me the most is that it does it with a freakin live wallpaper lol. I guess the snow falling in the skyrim live wallpaper triggers it or something but it is annoying and still exists in ICS. Oh well, maybe they will tone it down soon... here's to hoping.

I'm running the newest ICS update (9.4.2.11) and it's still doing it. The dimming at 30% home screen scrolling still happens too. i'm pretty sure it's DIDIM

Possible to make the screen even dimmer?

Running ViperRez. Is there a way to make the screen any dimmer than the current lowest setting? . I find it is still too bright at night.

I remember it getting quite dim but you should search for a mod or script.
This should be in the Q&A Section though, not development. Happy searching.

get yourself an app like notification toggle or do it manually in brightness settings. automatic brightness isn't great cause it's always checking light levels every to confirm if brightness needs to be increased or decreased. notification toggle will allow any percentage and as many levels as you want. I use 10,15,20,25,40,50 and 100
youre gonna want to get this app https://play.google.com/store/apps/details?id=com.haxor&feature=nav_result#? t=W251bGwsMSwxLDMsImNvbS5oYXhvciJd. its free and it works perfectly and you can make it as dim as you want, even to the point where you cant see the screen on at all, i used to use it to text at night all the time. It also should save your battery, i could go two plus hours screen on time on wifi and be in the high 70s for battery on my inc 2
Quicker. It has screen dim in it. I use it every night.

This works perfectly! Thanks for the help.
I use screen filter too, but keep in mind that it only draws a dark overlay on your screen to let out less light. The LED back light is still at the same level, but less light escapes. So, it really doesn't help your battery since we don't have AMOLED screens.
Chainfire 3D has a "Night Mode" filter if you want to give that a try too: https://play.google.com/store/apps/details?id=eu.chainfire.cf3d
The free version currently has a red-, green-, or blue-only RGB channel filter, as well as Amber and Salmon colored filters. You can fully adjust the RGB values of the filter in the Pro version.
Oddly, there is no "balanced coloring" grayscale filter. Would need to use the previously mentioned app or buy the Pro version and adjust the RGB values equally.
Fun to try out at any rate.
I use Lux. It allows you to reduce screen brightness to completely black and unreadable. I don't know but I don't think it justs adds a transparent black overlay to make it look darker. It seems to actually adjust the brightness below the minimum allowed without the app. Here's a link to it in the market (there is a paid and free version) https://play.google.com/store/apps/...ps#?t=W251bGwsMSwxLDEwOSwiY29tLnZpdG8ubHV4Il0.

Second Screen dimming

Just got the V10 and the second screen dims after 2 or 3 seconds after turning off the main screen. Is there a way to adjust the timing when the second screen dims? The dimmed second screen is almost unreadable because it is so dim.
Ditto, the idea that this is a replacement for a notification LED is really damaged by the dimming. (It's not just me that bought the phone based on that idea, right?) What I've found so far:
With the screen brightness set to 0, the second screen dims fully a few seconds after sleeping. Icons become about as noticeable as dust reflections.
With the screen brightness set to 100, the second screen follows the ambient light sensor after sleeping. Under bright light it turns itself up to the point where it's useable.
I've been playing with all the LEDs that Light Flow sees, but at least without root, nothing has any effect. I might look through the /sys files later. We probably need to get root first to figure this out.
On auto brightness it seems to be that the device adjusts the dimmed display for the ambient lighting? It's not the easiest thing in the world to see, but it's certainly not hard for me to see what notifications I have. I really prefer this over a colored LED.
Light Flow settings
For what it's worth, here's my current setup, now that the T-Mobile H901 is rooted. This does no one without root any good, and I don't know how it would translate to similar LED managers. I've been using Light Flow since the Sapphire (MyTouch 3G).
Light Flow device settings: check direct mode, root mode, and run every command as root. The Nexus 5 force reset option is checked by default and I don't know if that's relevant (no calls yet). Everything else in the menu is unchecked.
Let Light Flow control lcd-backlight-ex.
In a notification, set that "LED" to Solid and to 255 brightness. Check Enable Mixer and App controlled flash. With that last setting, the app will reset the brightness every few seconds even if the system dimmed it due to an ambient light change.
Now I need to edit some notification icons to be big and colorful. I wonder how this will impact battery life? Now the app is going to be awake all the time.
I've noticed that today on auto brightness the second screen will increase in light but not much. It also is not as smoth of a transition as on main display. It kinda jumps up real quick..
Yes for me I've noticed on Auto brightness the second screen will dim in a dark room and if you turn off your phone while in that room then come out... The second screen is still dim.... It's like th second screen doesn't respond to the light sensors at all unless the main screen is on.

Color would be cool. A classic CRT bright/lime green, for instance, would probably show up much better than the white.
We need to get on their forums with these ideas. Maybe some will get squeezed into an update
An app which turns off auto dim in case screen is off would be pretty much help. Maybe I'll develop one.

Minimum Brightness too bright?

The minimum brightness level on this phone is quite a bit higher than other phones with OLED panels. Is there any way to change this? Using power saving mode with the screen at minimum brightness makes the screen a bit dimmer and so does inactivity so we know the screen definitely has the capability to go darker. Anyone know how we can make the brightness darker?
P.S no screen filter suggestions pls

It's not a screen filter, what would even make you think that? Plus it does dim the software buttons. Maybe it's because you don't have root?
If you on 7.0, try "Night Mode Enabler" from the PlayStore.
On my Z Play, the Lux app does not dim the buttons either. I don't have root. OTOH I don't recall seeing in the Lux documentation that it uses root for anything?
Also, I'm 90%+ certain that Lux *is* a screen filter. I say that because it differentiates between two ranges of brightness: "above zero" and "below zero". It seems likely that the "below zero" settings (which are necessary to get the display very dim at all) are modifying the display data rather than the system brightness setting. Of course, on an AMOLED screen this should be just as good... except for those darn buttons!!
BTW, all of this "night mode" stuff has, unfortunately, just confused the issue for those of us who need to preserve our night vision while using our phones. "Night mode" has come to mean "make the color temperature redder" because that seems to avoid some of the ill health effects of blue light at night. But it doesn't do squat to preserve night vision---for that you need to get the brightness way, way down. If you're trying to use your phone at the telescope, you're just as screwed as before, only now, the google search terms are more polluted, making it harder to find an actual solution.
