Brightness at lowest level is still really bright?

I tried setting my Vibrant to the lowest possible brightness level (with auto brightness disabled, of course). It still seems very bright to me compared to the lowest level on every other phone I've used. I realize this phone has a nice screen, etc. but is there no way to make it dimmer in situations where you just don't need that bright of a display and want to save battery?
Edit: I want to clarify, I love the screen's brightness, I'm just mainly asking for battery saving purposes.

I was running a black bg for a while. It would seem to be your best option for both issues. It was said in another thread that black uses the least amount of battery.

You can get tinted screen protector....The bright vibrant screen is the best thing on this phone.

Yeah, that's not my complaint. No doubt this screen is awesome
What I mean is that I'd actually like to increase battery life further by going even dimmer, if possible.

Then a black background is a good idea, black pixels literally use no battery on an AMOLED screen because the pixels aren't on when they're black, so it's a true black. That's the wonderful thing about these screens, and why the contrast ratio is so ridiculously high. Also why the Kindle app has the color reversal option, making the background black and the text white, and a lot of the UI uses black in places I've seen stock android white or gray. I read a couple chapters of Sherlock Holmes the other day and my battery went down 2%. Awesome screen.

Also the web browser has a separate brightness setting.

**slow reader..jk
maybe one of the genius phone gods could post a mod for a supper dim night mode. hint/nudge :burning eyes:

I would have to agree even on low the brightness of the screen is very high. I didn't realize this until today my friend wouldn't believe me I had brightness on low (his Droid's screen looked like crap compared to mine ).
Thanks for the tip on the black background... I really do need to find out ways to improve battery life on this thing.

I made a similar thread a while ago. For me it's too bright in low light situations. I'd love to see a way to lower the lowest setting.

+1, i'd like to see to an option to go even dimmer.

Same here. The browser is downright blinding in low-light.

Hey I'm not the only one who thinks the phone should have much lower brightness settings. I think I've seen it dim lower than the lowest brightness, but only on auto mode and only for a short time. Or maybe not. But I'm sure it can go lower because it would be weird if it couldn't. I also much rather have dimmer colors than a black vacuous screen for battery savings.

It does go lower. Put the brightness on manual and set it to lowest possible then wait for it to timeout and go to sleep. 5 secs before it goes to sleep the screen goes dimmer. On the G1 the lowest setting was this pre-sleep brightness. On the Vibrant we can't get that level as an option. Fingers crossed a non-samsung rom like CM6 will fix this.

Good observation. Indeed hopefully its fixed in a custom ROM or even by samsung themselves (though i'm not holding my breath on that one).

Alarm Clock Plus
The "dim mode" in Alarm Clock Plus is really dim. It would be nice to have a setting that would allow me to drop the brightness down that much.

yeah, because even on low MY EYES, They BURRRN!
lol
seriously

+1 for supporting this thread!

+1 for lower brightness option.

+1 from me too. This thing lights that whole dang room when my wife is trying to sleep.

Sorry it took so long to reply to this thread. I had to go find my sunglasses.... Seriously though, I read in bed at night and yeah its way too bright.

How many of you guys only use MAX brightness when...

...showing your phone to other people to "show off" how great the screen is, but when you use it for yourself it is NEVER on the brightest setting?

i keep my phone on the same brightness at all times

Its the same as getting a nice sports car - when you have a friend, you always push the 6th gear to show off but hardly ever when alone.

I leave it on auto all the time. That's usually more than enough to emboss people.

I'll occasionally use it on a bright summer day, but normally I'm between 25% and 40%. Late at night when the lights are off I might go to 0%.

i leave it on auto.
if i want to impress someone i think quickly flashing dow14 will do a better job than changing brightness. lol.

Of course, I also have a 12,000 watt stereo that I listen to at lower levels every day than when I show it off. What is your point?

A majority of the time my phone is on max brightness. It is not good for your eyesight to constantly strain and try to read in low brightness.
The only time I put it on low brightness is in the middle of the night, when I wake up to check my phone, it can be too bright.
Also most people are not impressed by my phone, the majority of idiots are not impressed and still want an iPhone.

I used to leave it on auto, but often found it to slow to react our not bright enough in the car. Now have it on manual with 80-90% and find it much better.

How do you strain your eyes on low brightness? Minimum is sufficient everywhere except outdoors and in direct sunlight...

I'm usually indoors, so mine is ALWAYS on minimum, when i'm outside, i set it to about 30-40%.
When its like 1500 degress (exaggeration) outside in Texas, then its time to set it to the absolute max, or auto.

Auto is good enough to show off,
I always use 10% or auto only

Same, I usually have mine on min.. When I go outside where it is hard to look at, I turn it up some, but not much..

I have only used it out in sunlight one, and I took it up to 50% to do that. Otherwise I have a brightness widget that lets me take it all the way to 0% which indoors under my mat finish screen protector I find very comfortable and easy to see.
I don't know how much it affects it, but I get 24+ hours with Master's Axura 2.1. (Sorry I am not current Master, but you update too frequently for me to reflash if the change log does not have something I really need. All of your ROMS are good daily drivers)

[Q] Auto Brightness Changes Extremely Frequently

I got my GT 10.1 this past Monday and I have noticed auto brightness changes quite frequently. I can't figure out why. I don't think I am blocking the sensor but I don't know where it is...
Has anyone else had this issue? It's making me dizzy so I just turned off the auto setting but it seems like it should work.

Yes, mine does the same. I assume the sensor is next to the front camera, which I'm not obstructing. But the brightness level will change rapidly. I had to disable the feature. Found it default to a level too dark most of the time anyway.

I agree with it being too dark. At least I know I'm not the only one with the issue.

Same issue with me. Turned it off. I read that auto brightness burns more battery than full brightness cause it's constantly asking the CPU to make a decision regarding brightness.

Interesting. I always thought that one if the purposes of auto brightness was to conserve the battery.

I had this problem too. It would constantly change so i had to disable it.
Maybe samsung can put a fix out for it.

I imagine the algorithm included is very simple and uses very few cpu cycles, so I doubt it has an impact on battery life. Especially since it probably doesn't (shouldn't) run when the screen is off, so it shouldn't prevent the device from sleeping.
I agree the levels they have set are much too dim and make auto-brightness just about useless. I had the opposite problem with my Captivate, where the auto-brightness as too bright. Fortunately CM7 allows you to adjust the levels for auto-brightness. I hope we see something similar show up in a custom rom for the Galaxy Tab 10.1
Anyway, I keep mine set at 20% and that seems to work pretty well for me.

Where do you see the brightness percentage? I have a slider but don't see a percentage anywhere.

It's an approximation on my behalf.

I notice the same problem especially when holding the device vertically with my right hand on the front facing camera. I guess the ambient sensor is located somewhere where my hand is and thinks that I'm in dark room and automatically lowers the brightness. I also noticed that the brigthness change whenever I touch the screen so i guess its listening every time you touch the screen unlike the ipad where it refreshes evertytime it wakes up.

Is very anoying, i was moving my head while the screen increase the brightness and move my head and decrease... over and over. So i switch to a custom brightness.

Screen Filter

Maybe a useful post for some. I found this the other night, mainly because I was bored So if you use the app Screen Filter (which, by the way, is awesome for night time viewing in bed while the wife is asleep, you wont have to hear her say stop playing on your phone, because the screen is so bright!), but if you turn up screen filter all the way up to 100% brightness AND turn up your regular Android display setting up to 100%, you are basically getting your display level at 200%! And let me tell you...It is BRIGHT! I know this may be a useless post to most, but I found it to be actually very helpful in viewing my screen in direct sunlight, when the normal display brightness just wasn't enough.

Been using this app for months.

I am having problems enabling and disabling it consistently, but when I do enable it at 100% with my Android brightness at 100% I don't see any further brightness.
Also what is the advantage of this over the regular manual brightness?

I don't use it for brightness, I use it to dim the screen to a lower point that what you can do in the settings.

I've been using this app for a few months now. I love using it at night to watch a video in the dark, since the lowest setting for the brightness always seems to hurt my eyes in the dark.

That sounds unbelievable yet I believe it. I'd be concerned though that doing this might shorten the screen's life or damage it. As for that app it's been on my homescreen for a long time. Pretty essential.

Only problem is soft keys ofter are too bright for night veiwing

Screen Brightness

Is everyone here satisfied with the screen brightness? It looks somewhat nice when the brightness is at 100% but then that drains the battery faster.

I have never used the 100% brightness - outside I'm not using the G Pad, inside I'm somewhere near 50-65% brightness, and for night reading 10-20% brightness. About battery draining, I haven't keeping an eye on it. When the battery goes near 30%, I automatically put in on the charger (I got one sexy thin 4m. USB cable here so I can keep using the tablet anywhere in my room)

50-65% for me seems somewhat dim, almost too dim to enjoy the HD screen. Are there any additional settings other than the main brightness setting? I do not have auto brightness turned on at all

Indoors i hardly ever raise brightness over 40% i have no complaints. In fact 100% brightness is damn near blinding.

Agreed. Brightness isn't an issue. The problem is that the gamma is too high resulting in darks being too dark.

So can we change the gamma in the kernel ?

yes, I find the ugly screen (very dark) with the brightness below 60%.
by 100% against beautiful. But ouch battery !!

No, you can change the gamma (and saturation, and brightness and stuff) in an app, someone mentioned it here on xda, but I can't remember it's name. Take a look around

I downloaded screen adjuster but it does not have any gamma or saturation settings. Only red, green, blue, brightness, and contrast. By the way, does anyone know how to take screenshots on this tablet?

hold Unlock + Volume down

I recommend using the app LUX. It does a terrific job of managing auto brightness. Way better than the built in logic. https://play.google.com/store/apps/details?id=com.vito.lux

I'm slightly ahead with this advice because I haven't even looked into rooting yet. But I can tell you if Franco kernel comes out for this baby that's what you want. It fixed the gamma settings and the color settings on my Nexus 4 completely. Made it like a brand new device with beautiful accurate colors and amazing battery life to boot. I will be keeping my eyes out for Franco kernel.
