(Q) Auto Screen Brightness

Is the screen brightness supposed to drastically change when auto brightness is enable. I've been playing around with it and noticed that when auto brightness is enable the screen will drastically change in different lighting conditions (with a couple second delay) For example, ill walk into a darker room the screen will get a lot dimmer after a couple of seconds and v-versu. The reason I asked is that my eco 4g would gradually adjust to point t where I didn't even notice.

I've noticed it rapidly changing like it can't decide a few times, and overall it's a bit too dim outdoors. Coming from an Evo as well and I never noticed it changing either.
Just going to keep an eye on it, not a huge issue for me. Might see if there's any way to override and manually specify the auto brightness thresholds.

There's a second setting called "Auto adjust screen power" further down on the display page - it could be that. It's some sort of thing that analyzes what's actually on the screen and tries to adjust for it.

I think it may just be a samsung thing. I have a Galaxy Tab 7" and I noticed that it was doing this as well, and it drove me crazy. I just went into settings>display>brightness and turned it down manually to just under halfway indoors and if I know Im going outside, i turn it all the way up.

Ive also noticed thst it was auto adjusting even when i had it disabled which was probablt the "power adjustment" thing... But once i caught it turning the brightness down to "prevent overheating"!?

Really?! Thats bizarre. I wonder if it will constantly have the screen down while wireless tether is running.

Thanks. I also have auto adjust disabled. Since others are seeing it then I assume its a Samsung thing. Ill wait to see if others confirm. BTW this may just be me being a geek. I notice every little thing. The other is that the buttons at the bottom of the phone aren't as sensitive as the eco.

A tip I read somewhere but haven't tried yet is to turn auto brightness off and when you do, hold down on the notification bar (don't pull it down, just hold a finger on it) and slide left or right to adjust brightness on the go. Not for sure if it works but give it a try (I'm chargin my phone while it's off now so I can't yet).

Can't remember anymore besides the screen shot one which has been mentioned. Tap home and the power button simultaneously. Also can't remember where I read it.

I would honestly say its a combination of things BC I have used roms where its totally obvious (on froyo) where on others its completely impossible to notice the change.

I've had the brightness at the max, and turned off the Auto Adjust Screen Power option. Just while browsing XDA the screen dimmed, and when looking at the brightness setting it states "To avoid overheating, maximum brightness has been reduced.". This has happened at least three different times.
I'm hoping this isn't a serious issue. Have you had it do that multiple times for you as well?

Brightness doesn't stay where its set to

I keep noticing that my brightness is always set higher than where it is supposed to be.
I will lower it to about 1/4 brightness and by the end of the day I notice its at 3/4 brightness all on its own... auto brightness is off and power saving is off
What gives? Anyone else notice this?

Yep. I have he same issue. It has a problem staying where I set it. Especially when I set it to 0% do you use an app to set your level or do you go into settings to do it? I usually use quick settings.

Tasker App in CM10

I seem to be having issues running Tasker on CM10. It doesn't crash and it says the profiles are running but it doesn't do anything.
Is anyone rocking the Tasker on CM10?

Create a Profile that activates when the app is started, ending when the application exits. Start task should be auto brightness off, set brightness to 255. End task just turns auto brightness back on.

How is your task set up? And it also works to enable lux auto brightness at night so I would assume it can adjust brightness overall.

If your screen is set to auto brightness, you need to turn that off before it can be manually adjusted. Your profile should look something like this:
Starting YouTube:
Auto brightness: Off
Brightness: 255
Ending YouTube:
Auto brightness: On

I should try other profiles to see if it is me not knowing how to create them or the app or something.

I haven't made one yet but I'll probably make an auto sync toggle profile to sync mail, etc. I've been looking for some battery savers but last time I tried to disable data a la JuiceDefender I stopped receiving texts for some weird reason.

That's odd. I know for a fact the brightness adjustments work. I'm using the latest CM10. I just built a profile for the YouTube app and it works as expected.
Check attached images. Also, be sure the profile is enabled (green check mark), and that Tasker is on (On button, bottom right corner of screen).

What bothers me is that when I open YouTube, Tasker says that is running the profile but the screen brightness does not change at all. I will reinstall and see if it works and let you know.
I'm running CM10 8-14 version as it runs smooth with no flickering. I'm also running Justin bean inverted g apps, could that be the problem?

In your latest post with attachments, post #11, here is what you are telling Tasker to do:
1: When YouTube app starts, Autobrightness Off (don't know what this task contains, as there is no screenshot of it).
2. When YouTube app closes, Brightness set to 255.
Your profile still doesn't match my attached pictures on page one (or you haven't uploaded new screenshots). Make it identical to mine.
If it still doesn't work, I suspect its your version of CM10. Update it. I know that's not the answer you want, but if the above doesn't work, that's the only one left.

That's for all the help but it didn't work and I did exactly as you suggested. Take a look. It shows as running but it is not turning off the auto brightness. I have tried turning it manually before running the Tasker with no success.
I guess I'll just give it another try once I update the cm10 but I'm happy with the older version and wouldn't want to risk getting all the problem(flickering, echoes, call delay) present on the newer versions.
What version are you on?

Always running the latest version. Echoes and call delay were fixed last week. The only flickering that bothers me, is that when I exit certain applications (like Apparatus), the screen has a brightness seizure for a couple seconds. The other flickers look like a redraw; nitpicking. You can always nandroid the current install.

yeah in my GPS on/off profile it always spazzes out at random intervals. and even though i have the profiles connected to cell towers and not GPS or Net, im pretty convinced it's somehow draining my battery. i had no real issues with CM10 (aside from the documented flicker and call delay) until i installed and started trying to use Tasker. now the GPS is glitchy, the vibration turns on/off at random times, so does the wifi and worst yet, actual cell reception gets knocked out altogether. i've triple checked my settings and i know it's not the profiles themselves. i really hope the stable version of CM10 will play nice with Tasker because its such a sweet app.

For GPS, install Secure Settings. It's free and in Play Store. Never have an issue with it controlling GPS from Tasker.

Lux Auto Brightness

Has anyone tried this app for Nexus 4 (or at all)? I like the auto brightness feature, but the stock feature always makes the screen a bit dimmer than I like. Or another app that you prefer to do auto brightness?

Just go change the min value of autobrightness and will work just fine if you find it too dim.

Can you advise good stock settings? Just setting lux up, it tears though my battery. It doesnt seem to have any built in presets. Any way you can add a few to have a little base to start with?

I think the best solution would be like apple's auto brightness. You turn auto brightness on but can still change the brightness and set the "average" brightness higher or lower.
Because I am looking for a auto brightness which is simply a bit brighter in general as the stock auto brightness

Presets make no sense. I'd have to have different ones for different phones, so it'd be a pain to maintain. Just link a couple of brightness values and Lux interpolates the rest.
The battery usage of Lux shouldn't be high at all. I know some Samsung ROMs claim Lux uses a lot of battery, but it's wrong (I think it assumes the light sensor uses more power than it really does). On my Nexus 4 I use 'on wake' mode, which should use next to no battery.

I don't have control over the stock auto brightness which makes a feature like this hard. Linking values in Lux should work fine, especially in ascending mode which favours brighter backlight levels.

Anyone got any decent sample settings for this?
I'm using 0 as -20%

0/-30%, 1/10% and 10000/100% has been working good for me.

I've been tempted to try Lux again but find the free version doesn't really demo the apps potential very well. I'm always skeptical before purchasing apps as the refund window is way too short to test the app in full.
I basically want auto brightness to work how I feel it should, with the brightness not being high when it really shouldn't be very high. Stock auto brightness ALWAYS sets the brightness too high IMO, I'd love the ability to have auto brightness work at the levels I want it to have.

I tried it and put it away... Because when you go below zero your nav bar has still same brightness and won't dim :/

Lux auto brightness/auto brightness in general

So I've read a few posts from some users and saw a video in youtube but I'm confused. Does auto-brightness save battery life or not? Because some say it dims the display, but others say it's constantly using the light sensor to search for the lighting of the room (lux auto brightness uses the light sensor whenever the phone screen is turned on)
So auto brightness yay or nay?

I haven't noticed a HUGE difference in battery life using auto-brightness; on top of that, it always seems too dim for me anyway. I'd rather lose out on that extra 15-30 min of battery life at 100% brightness than I would strain my eyes.

I wouldn't draw that same exact conclusion; it would really depend on how heavy a user you are. I, personally am a pretty light user on average, so I wouldn't really experience much of a noticeable difference stretched out over 2 days... but for someone who is a heavier user, that difference could mean an extra 15-30 minutes. Not all that much, but definitely noticeable for people who have their screen on all the time.
