[Q] Brightness - Galaxy S II Q&A, Help & Troubleshooting

Just got my Samsung GS2 today. A couple of issues I've noticed. Auto brightness can not be turned off. When I uncheck the check mark, it re-checks itself.
Same thing goes with the GPS. Can't turn it off.

How are you trying to turn it off. Through settings or with widget. What version you using? Have you rooted it?

A battery pull and reboot seemed to clear it up. Thanks

Bug found

I think i found a bug. Please confirm if you have the same problem
i use my phone with below settings:
- brightness=auto
- screen time out=30 seconds
- auto adjust screen power=on
- power saving mode on at 30% battery power
Now when my battery is under 30% power saving mode works and decreases my brightness to %10 and screen time out to 15 seconds as i want. no problem so far
But after i charge my phone, my original settings (30 seconds screen timeout and auto brightness does NOT come back. it keeps using the power saving mode settings.
Any of you is having this issue? Please let us know.
I am using 2.3.4 stock and i had this problem on 2.3.3 stock too
yep same here, though I've set it to 10% for emergency cases
thanks for the answer
anyone else?
It's been reported by other users too. Mine does the same, but i stopped using it.
Interesting and I thought it was juice defender doing it. Yes I have too.

Brightness

I am not sure if this is an isolated or common occurence but on several occasions that my brightness setting is changing by itself. Now, i have made absolute sure that my setting is not on automatic and nor have i activated battery saving mode. I can for sure say when exactly this happens but it may be during/after charging. Brightness is always lowered when this happens. Any advice would be appreciated. Thanks.

The Brightness will only change in the Stock Web Browser if you had set it up different with system brightness, otherwise it should remain at a same level.
Regards.
This happens out with the stock browser.

Could it be some app you installed lately or is it just this way from the first?
Im not sure...have not had my device long and pretty much installed my apps straight away so its difficult to determine how and when it all started. I did update recently.

If the problem remains and you still haven't figured out if it's caused by an application or not then I'd advice you to do a Factory Reset, don't forget to Back Up data before.
Regards.
This was happening to me sometime ago! Than I noticed that my brightness gets lowered automatically when my phone overheats (while playing a game) and as a result it keeps the setting!
Don t worry about it! I advise you to lower your brightness to 50% before playing a game so that the phone does not overheat! It s one of the main factors that helped me eliminate overheating problems Hope I put your mind to rest
Thank you...that has certainly put my mind at ease now.

1. Go to Settings -> Display -> Brightness -> Set it to manual.
2. Go to Settings -> Display -> Auto Adjust Screen Power -> Turn that to off.
Hope that helps.

Auto brightness sucks on this phone, any fix?

Hey,
Had this phone for a week and the auto brightness is just terrible.
It is ALWAYS too dark, and sometime it would instantly go very bright and then down to very dark.
Whats going on?
I know I can keep it on manual, but I prefer auto as it saves battery and adjusts brightness accordingly.
Any fix for this?
maybe it'll come through siyah-kernel and siyah-tool (unpublished) on which gokhanmoral is working on.
No problem here.
Possible try a factory reset .

Constant wifi?

I noticed my wifi dies out when locked and getting bad battery life. I took a three hour nap and if went down 15-20%. I noticed my bfs galaxy notes wifi is constant(using the same wifi) even when his screen is off and he's at 14 hours at 40%.
So i guess my question is what is the norm as far as wifi connectivity goes and why does mine disconnect and his stay on? Defective device?

U can change the settings under wifi settings, press menu and then advanced settings.

Holy crap thank you. I had no idea there was an extra advanced menu. =]
Sent from my SAMSUNG-SGH-I717 using xda premium
Not really sure why this is kept under advanced settings menu..how i'd do it..
Wifi toggled off, hide wifi sleep policy.
Toggle wifi on, wifi sleep policy shows up underneath. Press on this, notification bubble(similiar to how you pick your ringtones/fonts) pops up with the two or three options..
I never understood the need to hide things in "Advanced Menus", just only show what's pertinent to what the user has enabled.
My battery was draining really quickly before I did this. Now everything is much more as expected.

cm7 questions

recently flashed cm7. Really cool. This place has a wealth of knowledge when it comes to this stuff.
I do have a few questions regarding cm7, however.
I've tried to search, i'm no stranger to forum etiquette. the search feature just isn't turning up any relevant answers to me questions.
Is there a built in airplane widget/app ? i can only access airplane mode via the settings.
Is there a built in task manager? (does it need one) and if not, would u recommend one ? Again, accessing running apps via the settings...
Can you freeze any apps? such as "talk" "voice dialer" "voice search" "torch" "news and weather" ?
This is more of a request than a question. But I would like an optimal setting for the display, as it's killing my battery. It's almost 50% of my battery consumption. I notice it gets brighter and dimmer sort of randomly... ? i know there are settings on this, but don't really know how to set them accordingly.
Thank you in advance for any help!

For app freezing invest in Titanium Backup Pro. To my knowledge that is the go to app for app management.
I have yet to find a task manager as I've been on cm7 for all of 4 days
As far as an airplane toggle goes, you can setup the power control widget to display the airplane mode toggle...which leads me to a random question: the **** does airplane mode do?
The random dimming is cause your brightness is set to automatic-- this can also be changed with the power control widget, which is built in.
Hope this helps!

1) Airplane widget/app: You can set it as one of the options on your notification bar by going to settings, CyanogenMod settings, Interface, Notification power widget, Widget buttons, and selecting Toggle Airplane Mode. That way it is easily accessible with only one swoop of the finger.
2) Built in task manager: no clue. I simply access running apps by pulling up by app drawer and selecting running apps.
3) Freezing apps: I swear there is, because I've done it... my mind is going blank. Will edit when my brain decides to work.
Airplane mode can be toggled by long pressing the top button of the phone. Task manager is not really necessary IMHO. As for freezing apps, titanium backup pro is probably the best for that. I think an app called bloat freezer existence off market but you might have to do some searching for that.

thank you guys. Found airplane mode, but i also found the toggle to turn off data, so that's basically why i wanted airplane mode. I live in an area with crappy service, airplane and data toggle help me extend battery life... basically so my phone isn't constantly working trying to find service when i know i don't have any... as far as Freezing, i have an app that can do it, i was just curious if it was safe to do so? Mostly the apps i had mentioned above. I don't wanna freeze something, then make my phone freak out. and have to nandroid or something.
and i just wanted a faster way to reach the running apps... i'm paranoid about apps running when i don't want them to.. lol
thanks for the help though guys. much appreciated.

Where did you find the data goggles? When I look it shows 2g and 3g and it is greyed out. I also used turning off data when not in use to save battery.
The data toggle should be right there on the same menu iirc.

I have ~20 apps frozen out of the maybe 50 I have and my phone is totally fine. So long as you aren't freezing something like your launcher, you're golden.
I feel the same way about running apps. Try advanced app killer. Its found in the Market, its totally free and easy to use. You can drag down the notification bar open the app and see exactly what is running and then kill anything you don't want running. There's also a one touch killer widget.

Ignore this...
Also for brightness control on the fly go to settings, cm settings, interface, status bar tweaks and check off status bar brightness control. Takes some getting used to but you can change your brightness by sliding your finger left and right along your status bar.

I just installed cm7 and am very pleased so far. However, I am noticing a significant battery drain compared to Blur. Is this anything anyone else is experiencing? If so, any fixes or is there something in the works from the CM team. Thanks a billion!
Droid X2 CM7
Give it a few days...the battery will get better. I would also suggest completely draining then recharging the battery until its been at 100% for 15 minutes.

Hmmm I think that is battery used while the screen locked and not in use. I've no idea how you'd regulate that other than turning the phone off altogether. Is phone idle draining more battery than your display? If so, that might be a problem.
Sent from my MB870 using xda premium
No, phone idle has never used more battery than display. So I guess that's good. Lol. I've noticed lately tho, that if I turn data on, I can literally watch my battery percentage drop. I've calibrated. And completely drained and then charged (uninterrupted) the battery.
I like cm7 though. Has lots of really cool features, but my main purpose for getting it was better battery life. ( which wasn't bad on stock) again, any and all input is welcome!
Juice defender pro. Watch it triple ur battery life.
Sent from my MB870 using XDA App
How would that help if he has problems with data on? Not with it off. Also, juice defender does nothing more than turn off data connections when your screen is off or when you schedule it to. Its much more efficient to do it yourself.
It could be a problem with the driver. I have this issue too on my G2X.
