Dark screen when opening camera - T-Mobile LG G2x

Recently I noticed that whenever I open the stock camera app the screen went very dark. I thought something wrong with the app so I installed another camera app and it had the same symptoms. Interestingly that the pictures came out all right. After some thinking I went to the display options, unchecked the automatic brightness and moved the slider from 0 all the way up to full brightness. That immediately solved the problem. So here is the FYI, it seems like the camera API disregards the automatic brightness option and always uses the manual setting.
P.S. I was considering resetting the phone because I couldn't figure out that nuisance at first. Luckily I didn't have to.

Fixed mine, as well.

There is also a screen brightness setting within the camera app.

[Q] Screen Brightness problem!

I love my phone, I haven't put any ROM's on it yet. Since I've had my phone my screen brightness will just randomly change. It's so weird. I almost always have the box checked for the auto brightness. Then every once and a while I'll notice that it's set to the highest setting, so I have to go in and change it back. Not a huge deal it just gets annoying. Does anyone else experience this? Is there a way I can fix it?
If you have it on auto, then it will change automatically depending on how much light is around you when you hold the phone. I didn't understand, if the auto setting goes off on it's own or what?
You're not alone. I always use auto but a couple of times now I've noticed that the screen looks very bright and when I've looked at the settings, the tick isn't in the auto selection box.

So, I have the auto brightness selected, and that works great for a while. Then I'll notice that the screen is exceptionally bright. I'll check the settings, and the phone just defaulted to the highest brightness setting. The auto brightness isn't even selected anymore. Not a huge deal, but I hope there's a way to fix it.

Yeah, I'll have auto brightness selected. But randomly I'll notice that my screen is really bright and not adjusting. So I'll check. And the auto is no longer selected, instead it is set to the brightest setting. It's super weird. I'm glad to see that it's not just me. It happens a couple times a week. It's not a huge deal, I'd just like to find a way to fix it.

In case you're curious, I found that the camera triggers it. I placed brightness on lowest setting, then selected the camera app, and the brightness goes way up then doesn't change after you leave the camera. That's about all I know lol.

Screen dimming app.

If any of you other users out there feel that the whites on this thing are too awesome for super late at night like I do, I found a app when searching for a f.lux type alternative for android. I have been using this app to help ease the stress on my eye late at night. I dont know about the techical side of what it does, or any of the jargon involved, but it applies a filter of sorts to dim the screen further than what the phone allows. I been using it a lot lately and figure I would share with you guys. If anyone has any recommendations for other similar apps, please share.

Or just turn on "Background Color" in Power Saving Settings.
Or if you want the screen brightness itself to be lower than what most ROMs allow, you can use this app called RootDim. It worked amazing on my xoom, not sure if it works on the SGSIII yet..
It requires root though..

Screen filter does the same and doesn't require root. On our AMOLED screens this can save battery.
Also you can turn off those damn capacitive key lights by going to Settings>display>"touch Key light duration"> Always off.
I can confirm that Root dim does work for the SGS3 I use it on my phone.

Lux is an amazing auto brightness app and setting it up for your tastes is incredibly simple.
Go out in the sun and turn brightness up all the way using the app then "link" that setting, go in complete darkness and set it to your taste and link it, then indoor lighting, set it, link it. It then uses just those 3 settings to create a smooth graph of brightness values that are all perfect. You can have as many links as you want but i find the less settings you put in that app the better.
I tried all the suggested ones in here btw.

I've tried and really like Lux (in fact I'm considering purchasing it soon) but I've noticed two issues. First is that sometimes it will not refresh itself and I have to open up the lux dash to get the brightness to change. It doesn't happen often, but it happens often enough to be annoying, and I have it set to automatically.
Also, (and this may simply be an issue with the S3 and not lux itself) but sometimes I will be in a decently lit room and be at 1 lux, while lights out is 0. Not a lot of variance unless it's really bright outside. Have you found anyway to increase the light sensors sensitivity?

Try setting it to be always active in the task bar, that prevents it from being killed. Also try setting it to not use raw values for light sensor readings, this gives you a simple scale of 0-10 for readings and total darkness always reads as 0.
Edit: oops reread your post. That's weird that it is reading indoor light at 1. I usually get around 2 or 3. I used to have a screen protector on that covered the light sensor and that put it all over the place. Maybe that is what's causing it?

I noticed the same behavior with the free version. In my case, the lowest value the HTC Desire S can reach with its default Android auto brightness is in fact about 15%.
In LUX settings you can configure the "0" value to be lower and "bypass" the freeware limitation (you can't configure sub-zero levels in the free version). This will work when you test it in the dashboard, but during regular use the light level never goes below the 15% limit already set by the OS.
What I did was purchase the full version (to get astronomer mode along with all the settings unlocked) so I was able to leave the 0 level at its default 15% but link some light intensity values to sub-zero percentages. Guess what? It works great! Once you go into a very dark room, the display dims as far as you set it to.
Another problem with the free version was that a few times I unlocked the phone outside in full sunlight and LUX did not increase the brightness. It appeared almost completely black because the light level was at about 15-25% (the same level it would be inside a low lit room).
Again, with the full version I did not notice this problem (I've used the free version for 1 day and the paid version for 1 day but running tests in different light levels inside and outside).
It's like the free version is a bit buggy on purpose, and I remember uninstalling LUX free about 2 months because of this; I was thinking that if the free version does not work OK, I shouldn't buy the full version. Apparently this is not the case (touch wood).
Just for the record, it's on "dynamically adjust".

If the display is a bit dirty (oily, dusty, etc) around the light sensor, you can try to clean it. If this is not the case, open the dashboard, let it determine the light level or hit "auto" a few times and make sure the reading is correct. Then just slide your finger along the yellow line to find the appropriate brightness level and long press the chain to link. Go to a brighter lit room then go back to the first room and see how LUX behaves. Also lock/unlock the phone a few times and see how it goes.
If you still have problems running LUX, disable it and check the default Android auto brightness to make sure it's not a sensor issue.
LUX also has the possibility to set the response delay under Settings -> Advanced -> Developer Settings (the last to just on the bottom, but for this you would need to buy the full version.

Thanks, but I think it is more of an issue of the sensor not being sensitive enough. I'm not sure if this is anything you can change in lux or if it would have to be edited in the kernel (or if it is fault of the hardware) but I just feel like the sensor doesn't go down low enough. As I said, I can get down to 1 or 0 in a decently lit room, and yes I have tried cleaning the screen. It's not like it jumps around or anything so it's not like I would notice anything in default auto brightness, it's just that it doesn't seem to be sensitive enough.
Screen filter is great!! I use as well!!!

Well for my Desire S, the lowest light level that the sensor can read is 160 lux (raw value). You can try and set LUX to use raw values because this is more accurate in my oppinion.
Another +1 for Screen filter here
Does anyone know how to use "luma" values for automatic adjustment in Lux instead of "lux" values?

What I have noticed on my phone is that "luma" readings are taken from the front facing camera, while "lux" readings are taken from the ambient light sensor (you can chose which one to use in the settings).
I suppose the front facing camera uses more battery than the light sensor; it also appears to be more sensitive because it can read more light levels.

I guess so. Thanks! But doesn't that kinda defeat the whole purpose of Lux? Because you can't use automatic mode with the camera(s).... so then what's it good for?
Well even if you don't have an ambient light sensor, you can still use the camera to check the light level when you unlock the phone and let LUX adjust the brightness level. Of course it's not dynamic but it's still better than having the brightness at 50% the whole time or changing brightness levels through a widget..

[Q] Auto brightness

What am i missing regarding screen auto brightness? I keep having to manually change brightness when going from light to dark places even though i have "adapt to lighting conditions" ticked?
It feels like im wasting battery having the screen so bright at night unless i turn it down, then I have to turn it up again in the morning.. Some secret setting?

Same here, Someone said that the screen does dim but it does so slowly so you barely notice it! Hoever iam not convinced! Iam almost certain mine is not adjusting at all
For normal day light conditions i feel the auto brightness adjusts very well. Its definitely better than the s4 i had. I have the auto brightness selected and the bar at 50%. I agree for night time reading i have to manually adjust the brightness may be its not as quick to adjust in very low light conditions compared to day light
I was using CM11 on the S4 which had very good brightness control, not sure about standard. I agree during the day I don't have problems at all, and the screen is very good. It's just when I'm somewhere with low brightness and I have to turn it down, and then when I go back into day I have to turn it back up again. Pretty annoying having to change it all the time.
I will get an app to do it for me for now, but this must be some sort of bug this action couldn't be on purpose.

I find the auto brightness not very good.
Sometimes when the lighting condition does not change, it will start to increase/decrease the brightness to the level which does not suit the lighting condition.
It also have the tendency to favor lower brightness.
Thinking of trying out Lux Auto Brightness instead.

I don't know if you mean to test the sensor, but the sensor works absolutely fine (with other apps)
My auto brightness works just fine and i have mine on lowest possible setting.

Auto brightness issue

I have started getting a problem with the auto brightness switching itself off.
I keep switching it back on and then after a periods of time... Can't be specific but when I come out of an app or having been watching a video and go back to the homescreen it's really bright and the auto setting is off again.

The only reason I know that auto-brightness would be switched off is if an app you installed does it inherently. Maybe you installed a gallery or videos app that turns up the brightness when you view a picture or video?

I had this exact problem. Found a solution here on the forum. If you've installed the Samsung Car App, un-install it. It was causing the auto brightness to turn off automatically.

Photo pro brightness

Been trying out then photo pro app. Noticed that when I'm in the app the screen goes really dark to the state where I had to adjust the phone's display brightness as I can't see what I'm capturing instead of bringing the brightness up automatically when capturing pictures. My old phone automatically brings the brightness up when the camera app was launched.
Anyone else having this issue as well?
