Focus/Omnia 7 auto dimming - Windows Phone 7 Q&A, Help & Troubleshooting

is there any way at all to disable the screen from dimming on backgrounds with too much white? i think its ridiculous that they built this functionality into the phone without an option to turn it off, is there anyway to tweak the registry? i got the phone because of the screen but if i cant enjoy bright backgrounds n what not theres not much point

There is a option for that. "Screen brightness", switch from Auto to Low/Med/High

no thats not the issue, i have it on high with auto off, yet it still dims when theres too many white pixels on the screen, apparently its built into the samsung driver for the screen, really considering returning it due to this

I immediately noticed this effect when testing an Omnia 7 in a mobile phone shop here in Switzerland and I found that quite annoying.
Try moving from page to page in the Office app. You'll notice a decrease in screen brightness when more white pixels are shown. At least that seems to be how the built-in algorithm works.
I prefer the 4.3" screen of the HTC HD7.

Brightness lower limit?

I was trying to lower the brightness very low to test how it would affect battery drain and it seems that the phone won't let 3rd party apps lower the brightness lower than what you can set it to, in the phone's settings. I tried an app called timerrific that lets you schedule various settings changes, but the phone seems to be overriding it. When I set the brightness to go down to 15% via the app, it does go very dim, but then immediately bounces back up to lowest level the phone's settings let's you set it at. Also, I had auto brightness off and the power saving mode off.
Has anyone been able to get the phone to go to very low brightness?
Thats a good question and would like the answer too... to me, the lowest brightness which must still HOG the battery as sometimes it seems to drain very fast with usage (and I have it on the lowest setting)... seems overly bright. I would without a doubt use it at a lower brightness to conserve energy depending on what I was doing at the time.
hey maybe its just the screen that makes it look bright

Not sure what you mean? For example, if I set the brightness to go down to 5% through the app Timeriffic, the screen will dim down to where I can barely see anything, but then it immediately raises back up to the lowest setting you can set in the phone's normal settings, which seems to me to be about 25-30%.
Yep

This is actually correct, the screen is what makes the "Automatic" brightness setting on the SGS phones look brighter than their LCD brethren. As we all know, currently all AMOLED displays use some kind of Pentile Matrix. All HTC devices (The N1 included) currently use RG:BG Pentile Matrix.
Do a google search on: "RGBG Pentile" and Samsung's site details it.
The SAMOLED display Samsung has made uses a new Pentile Matrix called RGBW:
Do a google search on: "nouvoyance" and it's the first site (sorry for the odd instructions, won't let new users post links )
Using the new RGBW, a white subpixel is introduced on top of the standard RGB stripe. From my reading, this allows the screen to achieve the same resolution to the eye with 33% less subpixels and is a brighter display in the process.

Good explanation, but are saying that no you can't dim it to low levels because it makes it look brighter than it is? If so, I don't buy it. I see it being dimmed to a low level. It just doesn't stay there.
Aldiko reader can get the screen even more dim

Also since there is less air gap in the new display, it is brighter.

This is just me speculating, but I'm thinking maybe the brightness setting is universal to android devices, except that it's calibrated to normal lcd. So the same voltage(or however they regulate the display brightness) on an LCD will look brighter on the Super AMOLED. For me, the dim setting on the auto-brightness seems too bright.
One thing I've noticed is I can take the brightness down to its lowest setting and it still seems bright..however on almost every phone I've used its like this.
The weird thing is on the Captivate I can open the browser, men then scroll down to settings and it has a brightness toggle there that takes it lower.

Yeah that does take it down lower than the home screen by a small amount. I put the browser brightness on the lowest setting and the global brightness on the lowest. Both auto brightness and power save are off. When I switch from the browser to the home screen, it brightens up a touch. So, it does go lower, but not all that much though, and it's only for the browser.

You can totally dim it more. In doing so, it will use even less power than an LCD screen at the same brightness setting.

Yeah, that's what I thought was cool about this type of screen, but I still don't know how to to dim it below the the lowest setting in the phone's control panel (which isn't very low). 3rd party apps I've tried don't really work, or they work, but the phone immediately raises it back up. Are you saying you've dimmed it down to where you can barley see the screen, like 5-10 percent? That's what I'm looking for confirmation on. If so, what app did you use?

I have used this app and seems to be pretty good, makes the brightness lower than system brightness.

I tried this app, and while it's a good app, it still doesn't make the screen go super dim. It looks to me like the lowest level (0%) is the same as lowest setting from the control panel. Zero percent should really be totally black.
Screen Filter
Here is your 100% working solution.
It doesn't work with the bright level, it applies a shade/filter to the screen. No matter what app you're using.
Set the bright to the lowest with your default system settings, because if you use a third party that goes below normal, with some apps like explorer, it set it to minimum allowed be system or whatever you set and then you will notice a setp up, shaded but a change.
I'm using it weeks ago and I found it's the best choice to suft the web at night. Also you can turn off softkeys lights

[APP] SuperDim

RootDim (formerly known as ScreenDim) lets you set the screen brightness on backlit screens below what the OS normally allows, which is handy for amateur astronomy where the lowest normal OS backlight setting (even with a red nightmode) leaks enough through the black pixels to damage night vision. Moreover, SuperDim lets have several brightness profiles, and to include nightmode settings (enabled by ChainFire3D or Cyanogenmod's render fx) as part of the brightness profile.
Needs root.
Public domain, source code available. In Market (search for RootDim).
Now in Market (free, no ads).
I just uploaded version 1.10, which restores low brightness settings after the screen is turned off and back on (the OS normally was restoring its brighter screen).
Works well, but seems to mess with the functionality of the notification/charge LED (Nexus One, CM7.1)

I assume this is when you use the other lights option to toggle these lights, or when you restore a profile, right?
In version 1.11 (just uploaded), I no longer restore other lights when a profile is loaded--this should help with your problem, as long as you don't touch the other lights. Eventually, I may add an option to choose which lights get restored from a profile.
I originally made SuperDim for setting very low backlight settings on LCDs, and so I made it not work on non-LCD screens (e.g., OLED). But I've since realized that the profile feature might be useful for non-LCD users as well, so I've released version 1.20 that supports non-LCD screens. It's in Market. While I was at it, I cleaned up the code a little, made it more javaish (I'm new to java).
My MyTouch 4G just seems to turn the screen off totally if i go below 20 brightness, it dims but then shuts off.
Doesn't work at all with Dell Streak 5
I'm sorry to say, but Screen Filter does the same, but doesn't require root.

Actually, all Screen Filter does is dim the colour of the pixels. This app actually modifies the screen backlight level. E.g. Screen Filter just makes the screen gray-er.
Also, works good on Sony Ericsson Xperia X10, but the backlight completly switches of when set to under 15.

Screen filter merely adds a black semi-transparent overlay across the screen, making it look dimmer.
This app adjusts the backlight, which means darker black levels on the screen.

Your eyes would probably care if you were doing amateur astronomy under a dark sky (which is the primary purpose for SuperDim). Screen Filter doesn't turn down the backlight, and on a lot of devices there is enough backlight leaking through even completely black pixels to damage night vision. You can try this experiment. Turn a backlit device to a completely black screen (maybe view a black jpg) and take it to a completely dark room. Let your eyes dark adapt. The "black" screen will in fact probably be quite grey. (If it's really black, that's probably because you have an OLED device.)
When I do amateur astronomy, I am not infrequently looking to see objects way dimmer than backlit black pixels.
I'd like to do something about the screen turning completely off issue.
To that end, I need people to do some experiments for me, and I will be very grateful (I'll also give a free full version of Force2SD as compensation for the first couple of experimenters, if you want it--just email me). The first experiment is this. Download SuperDim 1.22, now up in the Market. Press the menu key, and choose "Turn on safe mode" (you can tell safe mode is on, because next time you pull up the menu, it says "Turn off safe mode"). Now, turn brightness down to 10. Does your screen turn off?
I should warn that very low brightness levels can be very low indeed. For instance, if I am outdoors on a sunny day, I have trouble telling the difference between brightness 4 and off. So you need to be in a dark area--I recommend a room without windows and with the lights off.
If the screen does not turn off at 10, turn it down to 5, and then 1. Let me know if it ever turns off.
I am guessing that in safe mode, it doesn't turn off at all.
What safe mode does is it makes very low brightness settings not persist. So if you are in safe mode and leave SuperDim, you lose your low brightness setting.
I'd also appreciate it if people who can normally turn their brightness down to 1 could do some experiments with safe mode. Specifically, I'd like to know if moving the slider to 1 in safe mode has the same effect on screen brightness as moving the slider to 1 in non-safe mode has. (Again, if you're one of the first few experimenters and want a free copy of Force2SD, email me.)
On my Archos 43, brightness 1 is very, very dim, but the screen is still on. And I can't tell the difference between safe mode and non-safe mode, except that in safe mode, the settings don't persist after I leave SuperDim.
Tried this app on my desire HD.
Great idea, but when I reach 10 and below, the backlight doesn't get lower.
If I use the adb method (don't remember the command), I can set the backlight manually all the way down to 0.
There is no difference with or without safe mode on.

What happens? And does safe mode work?
I agree, doesn't work with Desire HD/Inspire 4G, safe mode only dims the brightness but no lower than normal, and only dims the brightness on the screen, regardless of your settings

I found a bug. In fact, the bug is such that I have no idea how it was managing to work on my device at all! In any case, I think I fixed it. Try 1.23 (should be in Market or here) and see if it does the job. If not, I have some more ideas.

[TIP] Surface adaptive display

I use a very dim display to save battery on the Surface or any other mobile device. The adaptive (auto) brightness feature isn't truly the best for the Surface for sure. I noticed that the screen flicks too much even though you're in the same environment. On reading about it on the web, I figured that this is a genuine problem for many on the tablet. Bad design maybe. So instead of reducing the brightness to minimum, I kept it at almost like 7-10% and voila ! The display is now as crisp as its supposed to be ! I wouldn't guarantee if it won't flick at all, but trust me, its like 90% better
Enjoy your new Surface !
screen flickering
Hi,
I've also noted some light flickering issues on my Surface (that I really like) even if the auto-brightness feature is off and with 100% level.
Generally speaking, it's not visible unless :
- you're scrolling quickly through the start screen
- you're closing an app with the proper gesture
It seems that for half second the scrim flickers...is it also happening to you ?
I was considering a RMA but I'm not sure if it's more a SW problem than a HW one.
Thank you for your answer.

I think its more visible when you're on the Metro UI or the Start screen. And more on when I am scrolling from the side of the screen, just like you said. Its pretty weird.

Display is slightly blinking in specific conditions

Yesterday i noticed something strange in my OP7p and i'd like you to check whether something like this occurs in your phones. Issue, which i will describe occurs only when i have 90hz refresh rate set and the low brightness of the screen with the auto adjustment of brightness turned off. The easiest way to see that is on youtube application with a dark theme. When we start a movie on the full screen (horizontally) and watch it for a few seconds, then go back to the vertical position, there is something like weak but visible blink of the screen, or a minimal colours change. It can be noticed in other apps, e.g. on facebook. Seems to me this is a software problem, beacause the same phenomenon doesn't exists when we set 60hz refresh. I would be very grateful if you can check it on your phones and give me a know about it.
I don't usually start videos in full screen mode and never noticed it but yeah definitely does a white flicker.
This is the highest brightness I could get it to do the flicker at.
Thank you for an answer. Personally i am able to see this flicker on a little bit higher screen brightness, but maybe its because im sitting in a dark room now. I was worried cause sometimes i see it during the normal usage of phone, and if only my OnePlus would be affected by this flickering i could still return it or exchange for a new one. It isnt very disturbing however interesting is whats cause of it.

From what i know jelly effect appears while we scrolling some content and propably that's not what i meant in my first post. Also flicker in my case is only visible on 90hz refresh rate.

Question S22 ULTRA- GREEN SCREEN WITH BLACK BACKGROUND

MY S22 ULTRA, 5 months old, began 48 hours ago to show the background of the lock screen (active display with a black background, in a very oscillating dark green color.
It only happens when the active display is activated, and sometimes inside with a dark background when it tries to adapt the brightness to the environment, it occurs as a kind of almost imperceptible flickering.
Internally the navigation, videos, photos and others are all perfect.
Things I have already tried:
Wipe Cache
Toggle between all screen resolutions and display options etc etc
With the mobile turned off while charging, if I press the power button to see the percentage of charge, that green is also seen.
I was reading that it may be a screen failure, but I still refuse to leave the phone in repair (150GB of internal information already copied), I don't know whether to wait for an update or what else to try.
Any suggestion?
Sorry for my english
I don't have answers for your issue, but I had exactly the same issue. I damaged my screen and it started appearing right after the damage to the screen. I don't use AOD, but mine did the same thing when it was put on charge.... no black screen, just the weird green. I turned off adaptive display and it disappeared. Had 2 updates since then and put back adaptive display and now the green is still gone. Not sure if was an update or the adaptive display change that fixed the issue

Can it get worse or will it always stay like this?
I just replaced the screen protector and it's still the same sometimes, not always, it seems to improve things but it only appears if I force the situation with dark environments.
How do you explain if it was a screen problem, within the android there is no display problem in photos, videos etc etc
It only affects the active display and while the adaptive display is active, that's why I don't want to send it to warranty so soon, I even hope that with Android 13 it will be solved!
To those who had to change the screen, did it come under warranty and the fault has been recognized without having to pay anything?
Obviously, if it were the screen, it would have to be some sensor or sector of the screen that only acts under certain conditions and I don't know at the hardware level what it could be, if any sensor or sector of the screen is internally damaged, it is very strange.
Thanks for answering.

It was everything free, they replace the display circuit controler, the display and battery (mandatory on note 8 if you replace the display they replace also the battery).
The problem was stable, no true black, allways greenish, sometimes flick and turned true black for couple of seconds and returned to that greenish black. Was horrible, my luck was i had 24 months of warrany and this happend on my 22th month!
Hi, I have same problem for 2 weeks now. Seems to occur when in low light placed and adaptive brightness is on. Did you find solution?
