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 use brightness level too but the brightness goes back to the highest level when you plug the phone in and you cant use the presets on the widget anymore

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

I have had my TF300T for a week and a half now. Whenever i watch movies in full screen, you tube, actual file on my tablet, flash video, or Netflix. the screen seams to adjust its brightness randomly throughout the video. I have ensured that i have auto brightness turned off, and have tried this on all three modes (performance, balanced, power saver). I get the same results in each mode. If i set the brightness high enough there is no auto adjustment of the screen brightness, but this is pretty annoying because i either have to choose between sucking my battery dry or dealing with the brightness randomly changing. Am i the only one having this issue? remember this only happens in full screen videos.

This happens to me too when I'm watching at the lowest brightness point, just raise it a bit and it should be okay. Anyways ASUS need to fix this too.
Thank you for the fast reply. I just wanted to make sure that it was not a defect with my tablet before i go past the return policy. I think i will call Asus and let them know about this issue to get their attention about it.
Has anybody else experienced their screens changing brightness randomly?
I have mine set to full brightness and it will randomly get slightly dimmer for a few seconds up to a minute before going back to the original brightness.
It's sorta hard to notice unless you're looking at an image with a lot of white (Play Store, webpages, etc.)
My first N5, which I RMA'd for other defects, also did this.
Any guesses if it's a software or hardware issue?

hi folks,
I just got an n8010 and I like it alot. only thing thats bothering me is the display brightness during video playback. for normal use its fine and I set it to about 4o%, but for video playback even when set max brightness its still not bright enough. have tried all the usual players. is there a video player that can increase brightness? or a different rom that gives higher maximum brightess? I also have an acer aspire one 725 netbook, and its screen brightness is much better for video playback.
thanks,
gary.
I have the same issue.

its weird. the tablet is capable of being uber bright, yet for video not bright enough. its a shme, its the only thing I dont like about this tablet. thinking of trying a tf700t instead.
Have you made sure that power saving mode is off? It limits screen brightness, and I would guess it tries to do this especially if you are doing something that keeps the screen on for a long time, like watching a video. Also, you should check under the display settings, since there is a setting that tries to optimize the colors for different use cases. It's called screen mode. play with those settings a bit and see if your experience improves any. Finally, make sure auto brightness is off, and then you can manually put the brightness all the way up using the slider in the status bar.
Hope I helped you.
Tried all the options. It has an outdoor mode which is brighter but seems to really wash out the color. Max brightness is a good start as auto bright is never enough to watch something in thus tablet. I'm hoping to find a way to increase the brightness even more tho.

Try using MX Player and slide your finger up at the left edge of the screen while playing. This player's screen brightness is independent to system brightness, and on my device its max brightness seems even brighter.
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.

this is usual for EVERY Oled screen and is called jelly effect...
You might want to try the DC dimming option in Settings->Utilities->OnePlus Laboratory.

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.
I have galaxy s7e as a second phone and that effect doesn't happen there.
