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.
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

I looked everywhere but found no real solution.......
Tried flashing new rom no luck ...
This was quite common with the S2, what you can try is to power off your phone and remove the battery for 20-30mins, if the same issue occurs either the battery sensor is messed up or IDK.
Happened with my infuse in the summer out in the sunlight and i posted a topic in there about it. They say its normal
Well I tried this still not working .....

Same problem here. Even i charge my Note also is heating. Dun know why.
Screen bright again
I dont know what cause this problem, but I got the same thing on my phone. A temporarily solution is to install Brightness Level from Android Market. It does not fix the problem in the system settings but it makes your screen 100% bright again

Is there a way to remove this protection?
When I have the gps in the car I get that all the time, even if the phone is not hot at all, very annoying because with the sun and sunglasses -> cant see the screen very well.. stupid!
If you have one of those tpu softcases you will not know whether or not your note is hot just by the feel. Those cases are terrific insulators. I had overheating with the Note on GPS and charging. It actually shut down once and dropped out of the GPS signal a couple of times. Took the Nillikin case off and found that the whole phone was very hot.
After the case was removed I continued the trip with four days of continuous GPS and on charge with no problems. Even with the TPU naked, it still got pretty warm at the top half of the phone, but worked fine with brightness set pretty high. I think this is normal for the Note
[FiX] Galaxy Note ICS OVERHEATING PROBLEM SOLVED
[FiX] Galaxy Note ICS OVERHEATING PROBLEM SOLVED:
1 Go to settings- developer options - UNCHECK "Dont keep activities"
2 Use go launcher ex (or some other good launcher...) instead of default launcher
3 Instal from google play android assistant and use it to clean cache and stop most of background process
4 install from google play "cpu master free" (MUST HAVE ROOTED PHONE) and set 1000 MHz for MAXIMUM, and check box "set on boot"
P.S. DO NOT expect that your phone will be cold as ice after you do this...
ICS is build that you can use max. out of dual core, and galaxy note is pretty slim and back is made out of plastic...All that increase heating problem...
Hope i helped! =D
download the free version of "watchdog" and it will give you an alert if any software uses a lot of cpu power, you might have to go into setting and add system process to the watch list, you can also whitelist and blacklist program so they are killed as soon as they cpu usage goes above a certain level, though this might be pro version only.
Only use watchdog to find the problem and then remove it as it can use quite a bit of cpu power itself.

Having modded the framework for my rom to include lower brightness mod i can say that the values set in the decompiled framework are virtually the same as gb values infact brightness was increased at the lowest level from 32 in gb to 40 in ics with powersaving mode set to 32 in ics

I see no difference at 38 and below in LQ3. The lowest dim at 39. At 40 the brightness will then increase.

Hi legion =)
I most often use phone at 100% brightness simply just because I like it when the screen is bright and clear, colors appear nicely too on high brightness. And outdoors in sunlight its sometimes hard to see whats on the screen even though brightness is set to 100%. You were right about the burn-in. Can see some burn-in if looking very carefully, depending on what colors there are on the screen over the burn-int areas. But still they are so weak and hard to notice even when you know where to look for those areas that I will probably have bought a galaxy note 2 or maybe even 3 before they appear clearly visible and too annoying to endure

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%?

and like I said, why do I care if it is changing brightness to levels I can see for the given light I'm in what does it matter? Apparently it is doing something right.
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.

My setup for auto brightness is +2
Reaction time from dark into sunlight is almost immediately
Reaction time from sunlight into darker area takes almost forever. It takes almost complete darkness for the screen to go back!!
Normal or not??
Thanks for any reply.
Gr. Marc
I noticed that too - The screen get brighter in a matter of nanoseconds but when I am in a dark environment it takes a minute or two and sometimes it never turns the brightness down. Hope they'll fix that with an update or something soon.
Anyway, what I did to go past that is turning down the brightness and then setting it back to auto brightness when I am in a dark environment.
Normal. But rubbish. Lol.
