I noticed today when I was outside that it was hard to see my screen because I always keep it at the lowest brightness level.
I bumped it up to the max so I can see easier.
I tried out auto brightness immediately after and it was much brighter than the brightest stock setting.

That's odd, so you're saying if you put it on the highest setting with manually configured brightness, it still won't go as high as auto brightness in a situation where its needed (like direct sunlight)?
I personally use the auto brightness anyway but that's interesting to know...

yeah i noticed that too. auto bright seems to go higher than the regular brightest setting.
If that's true, is there a way to manually increase the brightness to max?,
you know, similar to increasing the volume values?
Maybe someone can try it

yes, exactly.
the auto brightness probably kicks into outdoor visibility level.
Dose your phone say at the lowest light level. Because mine, even after I set it to the lowest level, moves to a brighter level.

Ditto, mine always finds a way to creep back up to higher brightness levels.
I think I'll just use auto from now on

I'm not real sure but the lowest manual level seems still too bright to me. I've seen lower with Auto on, but maybe its my eyes playing tricks again.
It is probably Power Savings in the Display settings that is STILL automatically dimming the display, so ot merely seems like auto brightness is brighter than manual max adjustment. Turning Power Savings off keeps the screen at 100% all the time --the browser and other apps will not dim the display anymore.

This is one thing that drives me nuts with this phone. I use the "dimmer" widget to drop the thing down to 10 brightness, but even that's way too bright and I haven't yet found an app that makes the display dimmer than 10 (I know that requires root, but none of the ones in the market seem to work with the Vibrant).

Maybe I'm missing something here, but I have power savings off and auto brightness off, and the screen still dims when I go into the browser.
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.
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.
Sent from my DROIDX using XDA App
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.
if I put the manual slider on 100%, and then tick the "automatic brightness", it stays at 100%, even in a fully darkened room.
if I put the manual slider on 0%, and then tick the "automatic brightness", it stays at 0%, even under direct sunlight.
What gives ? LG forgot to program this feature ?

I am not certain on this but my understanding of how the auto brightness works is that it adjusts within a certain % up or down of where you set the slider.
I am sure someone with a bit more knowledge will be along shortly to advise exactly how it works though
It appears to me that the 100% and 0% always do full on or full dimmed, whether you set auto brightness or not. Anywhere in between it does work with auto brightness, but the screen reacts quite slowly.
Auto brightness on this device is rubbish. Period. It doesn't work at all when you're set on 100 or 0 percent, and if you're in between, it works, but only buy using very slight changes to the manual setting that you chose. Why on earth did they base the auto brightness on the manual brightness???

auto brightness works quite well for me. I have it set as a 55% baseline and it always changes in more or less light. It takes a second but it will do it and works great. The slider does not show the change though.

No, it doesn't work well for you at all. If you put it at 55%, and go to direct sunlight, it will never come close to 100% brightness (I would say only about 60-70%). Moreover, if you go to a pitch black room, you will not get 1-2% brightness, rather ~30-40%. I would say the automatic brightness control of the G2, can only play with ~10% above/below what you set your manual settings. Who does automatic brightness like this ? pathetic and useless.

I also use a 3rd party program to control brightness. My phone would just randomly uncheck auto brightness on its own. Not sure why it sucks so bad on this phone. So, check out Velis Auto Brightness in the play store. It disables system management of brightness, takes over the job.

I used to use Velis too but it was a bit too cluttered for me. Lux was a whole lot more userfriendly. Plus it can reduce brightness below minimum levels and has a built in night mode that activates automatically. Found it best for my use.

whether it goes to 100% brightness or not it brightens up enough that I can see it clear as day. So why do I care if it doesn't get to 100%?

Have seen a lot of varied answers on this topic but having owned an iPhone in the past LG has set up their brightness controls to work in much the same way. You basically have two independent controls that can be combined to work together.
For example, I have my brightness on 85% and Auto is checked to ON. This means brightness will adjust automatically but never exceed 85%. You are setting a ceiling and it will NEVER go to 100% bright if set this way. If I turn Auto OFF, its always 85% regardless of ambient light. Hope this helps some peeps understand this better. I actually prefer their implementation but it's familiar to me.

This explanation contains logic, while LG's automatic brightness control, contains none. If you set brightness at 85%, and turn automatic brightness ON, assuming 85% set the top ceiling, then going into a pitch black room will still allow the LG to turn brightness to something like 5%. In reality, it doesn't happen, even in pitch black rooms, the LG is still close to 85% (maybe 65%), which is totally blinding. If you want to see how a working automatic brightness control behave, install lux brightness control.

I don't disagree with this at all....I'm still observing some odd/unexpected behavior and you're right.....it doesn't seem like there is enough 'travel range' when using auto in very dark environments. 85% in regular/full light should scale down dramatically in a dark room...one would think?
I actually prefer my screen brighter though so this hasn't bothered me, but that is personal preference and definitely not one size fits all. I have used the built-in controls on CM based ROMs on a few of my other devices before the G2 and you get much more fine-grained control there. I will say though that as far as the stock brightness controls go, the G2 behaves identically to the 2 iPhones I've used. If anyone reading is interested and has a friend with an iPhone, hop into the settings and look at the brightness controls. I think you'll see where LG drew some inspiration.
Loving this phone overall....best I've owned so far! I purchased off contract and sold my Droid RAZR MAXX HD on Swappa....couldn't be happier.

Did you use any android phone before the G2?they all work the same way,sony Samsung,lg....
You are right that the auto brightness should go from zero to 100% depends on the available light but all the brands i used have the same auto brightness.
I think it's something related to android.

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.

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.
