(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).

This was a feature in the original epic as well. It is pretty cool. I just use this to change brightness . The only time i change is when i go out in the sun.

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.

They kept the good features from the Epic. I like the feature in "Contacts" where you can swipe right on a contact to call them and left to send a message as well

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?

CM9 & touchkey/softkey backlight

Alright, hopefully I'm just being a 'tard and not looking in the right place. I took my phone from 2.3.6 to 4.0.4 last night, and I have allllllmost everything set up the way that I want it. The only thing that's missing it the backlight for the four softkeys (menu/home/back/search). I want them to stay lit whenever I have the screen on. I've searched, but all the threads that I turned up were people that couldn't get them to turn off!
Can anyone point me in the right direction, or is it something I just need to get used to?
Thanks,
n1n00b

Its a bug, sometimes they turn on sometimes they don't. I hardly pay attention to them anymore as I've gotten used to it

This is a known issue. They won't work when the screen comes on initially.
If you leave the screen untouched for about 5 seconds, they will come on when you touch the screen. You can also get them to come on by adjusting brightness. They will work until the screen turns off.

Not quite what I meant... I'm referring to the fact that, once they /are/ lit, if you don't touch the screen for a few seconds, they turn off. I want them to be on as long as the screen is on. You can set this to happen in the OEM TouchWiz OS, but not with CM9.

Not a fix lol easier to just adjust brightness from status bar to get them on...

I think I misunderstood. I thought you wanted them to stay on when the screen is on. The directions I gave you do that on mine. What was it you want the keylights to do exactly?
Personally I think the screen brightness is actually too bright except in when out in bright daylight.

Annoying Screen Timeout!

So I'm watching a video (expanded to full screen) on the stock browser at night in a dark room when the screen times out.
I can't find any way of switching the screen timeout off, and have to resort to setting the time to maximum and having to reopen the screen and restart the video every 10 minutes.
There has to be a solution to this annoying problem? Please?

Is smart stay enabled or is it just not working on the dark room ? If smart stay is not working then you can just pull out the s pen from it's holder or hover with the s pen instead of closing the video.

Fair enough, but there is "no issue."
Why have this phone if you don't use it? Besides, full screen is probably one way to AVOID burn in.

Yes, this avoids the screen burn. Screen burn only happens because some of the led's are used more than others which is why some degrade faster which results in varying color contrasts. Using full screen almost all the time however, uses all of the led's, thus all of them will degrade at a slightly similar rate and the change of color contrast would not be as noticeable to the common eye.

If you mean stock internet browser it will time out don't know why I streamed hell in a cell last week had the same issue doesn't happen on any other phone I know of just this one...I had to stretch the screen so it looked full screen and it stayed on strange I know

I'm having the same problem not sure why there would be this problem considering no phone for the last 4 years have had this problem. Terrible overt sight by Google/Samsung. Really interested if some one finds the solution to this.

Use Profile Scheduler from the play store it lets you set up a profile with a setting for screen time out never option. Thats the only reason I use it. I listen to alot of music in my truck and it keeps the musoc player from going to sleep.

Screen time out issue is only when watching flash enabled videos in browser.
Reason : Flash is not supported in Jellybean officially,
So just using flashplayer.apk will not rewrite screen timeout settings in system files.
And, smart stay doesn't work in dark room with lights off.

Screen stays on ALL NIGHT

I dont know if anyone is facing the same problem I have now, my n2 screen wont turn off by itself. I have set the timer on 15secs, smart stay disable. It juz wont turn off when idle. And if its fully charged, it will stay up all night as well.
Does anyone know how to fix this?
Does it relate to my Omega rom or Redpill kernel?

Just kidding, that's very strange. I noticed if you reboot the phone and don't touch it, when it comes on the screen never turns off either. Doesn't matter if it's plugged in or not.

It's not smart stay, not the screen rotate with your head thingy nor the developer option that keeps the screen on while the device is being charged. I turned all that off. This is clearly a big that I've had from 4.1.1. Can't get rid of it. Annoyance at its peak.

Are you saying that the screen just won't turn off, or that it turns itself on and then won't turn off?
If it's the first, my guess is an app which prevents the screen from turning off, didn't release its lock after being shut down. This can happen with some games, I've seen it with angry birds and jetpack joyride, titanium backup has done it too. Try to empty ram and kill processes, and/or reboot, though I would guess you might have tried that already.

If doesn't turn on on its own. When the bug kicks in, the screen doesn't go off if it's manually turned on or If a missed call or message is left unattended. Hope you got that. But yes, I can turn off the screen manually but doing that every time is ridiculously annoying. The bad thing is I cannot know if the bug is active or not without actually watching my screen till the timeout. Annoying bug! I've tried various things and I do not know what's causing this. I'm on stock rom, never rooted.
