[Q] Galaxy S2 Tuner or the like increase screen Brightness?

As the title states.
I do believe that my Vibrant's screen was brighter than my S2. Is there any way to use software to tune the brightness above 100%?
Reason I ask, I was able to use galaxy Tuner on the Vibrant to tweak a whole lot of different settings aboveand beyond what was specified from default settings.
Any feedback/help would be appreciated.
Thanks

Turn auto brightness off and adjust the brightness yourself in settings.

If you want the full brightness also make sure you have the "auto adjust screen power" option unchecked in the display menu I thought that an older iPhone had a brighter screen too til I unchecked that along with turning off auto brightness

just a bit of caution
the SAMOLED+ screens are super bright, it can blind you
make sure to not turn it to the max unless you are outdoor under a bright sun
basically don't need to go full strength in a dark room, or poorly lid room

I second that after I saw how bright this phone can go I made sure to recheck that power option n have kept the brightness at about 40-50% which is more than enough IMO

Exactly true. I always set the brightness to something like 5% of the full bar and it's bright enough. The screen is VERY bright...

Maybe i'm blind, I love bright! ! My vibrant is brighter. That shouldn't be the case. Any way to increase brightness above and beyond factory 100%? Thanks
T989 Galaxy S2! !

well you can flash Juggernaut ROM, it's very well fine tuned for brightness

Yup, got jugg v2. I'll keep looking. Thanks.

OP must be blind. Lol
There's no reason to need this screen any brighter.

Is there a way to reduce the brightness below 0%? The screen is super bright on my S2 even at 0% . Is there an app to go below 0%? Else I will go blind pretty soon.

Use screen filter u can get it in the market for free

i really dont understand why i would need this app ,personally my screen brightness never leaves 100 and if i could make it 125% i would ,you can adjust browser brightness in the browser settings and all you have to do is swipe across the top of your phone to lower the brightness ,dont understand how this app is useful. ipersonally think the screen could have been a little brighter .in complete darkness its gorgeous but in natural light during the day i find myself wanting it brighter .

Actually, I have the same issue. At 100% mine isn't so bright and driving in my car during the day it's quite dim yet set at 100%. so I back the OP in this issue and hope someone finds something. And those of you who insist he/she is trolling or not taking (stupid) hints, go play somewhere else. We've got a legitimate issue here and welcome anyone who can positively contribute to this thread. I'll post back if I ever find something. I remember using some app back on one of my old windows phones that did what we're looking to find so there should be something out there.

My Vibrant was brighter too...Also had a cooler tint to it. The audio on my vibrant was alot louder too.

The SGS2 is just as vibrant if you unlock the Auto Brightness

heres a trick i found. turn off auto brightness. then, just barely pull down notification bar and slide right to brighten and left to dim.... this works on MOST galaxy devices... not all

Two Defective Screens in a row. And I bet you have the same issue.

I'm calling all the GN owners to check your screen to see if you could duplicate the same issue I have on my TWO GNs.
Step:
1. Manually set your screen brightness to lowest brightness.
2. Go to a complete dark environment like in your closet or test this at night with all the ambient lights off. Again in a COMPLETE DARK ENVIRONMENT, this is crucial to duplicate the issue.
3. turn on the Camera app and look at the screen.
After your eyes adjusted to the darkness, you will see a bunch of nasty scattered pixel blocks. It's like pouring inks on your screen.

Both my phones ordered from expansys-USA and Negri Electronics have the same issue.

I do this about 7 times a day, it has to be a common use case right?
Seriously, do you see the insanity of recreating this non-problem? Just think about it.

The screen image attached to the OP of this thread also suffers from the same issue:
http://forum.xda-developers.com/showthread.php?t=1366878&highlight=test
How many more of you have this?

I haven't checked mine yet. But I don't really use my phone in the closet with the lights off, so for me, and how I use my phone, my phone kicks ass
I did use it on lowest setting with light out in bed last night for a few mins, and saw no dots. So it probably has something to do with the camera and what it is seeing in total darkness. Since it is not an infared camarea, I see no problems with that either

I tried this and couldnt see spots, mine does have the right edge slightly tinted issue though. All amoleds have variations theres over 200 pages in the galaxy s2 forum.

If you set your wallpaper to black/grey you will see it at your home screen.
I spotted this issue when I was playing with my phone before bed, it is definitely not a Camera app issue, it's something hardware related. Like I said before your eyes need to adjust to the darkness in order for you to see those dots.
This is pretty annoying if you use your phone at night with all lights off.

It's true that during normal usage in daytime you cannot see them, but I use my phone in dark environments a lot so this is crucial to me.

I have used my phone in the dark a bit. Kindle app set on black bg with brightness turned all the way down is the largest. I always have the brightness all the way down when using phone at night in bed so not to bother the wife. Have seen zero issues.

My first nexus had many stripes from the bottom to the top but my second one is much better.

Sounds like a classic case of someone looking for a problem. If a person has to take all the steps the OP described to recreate a problem, then it isn't a problem. Nothing to see here.

This is correct. And I think an easy solution would be to put the brightness at 15-20% instead of the lowest so you don't see whatever it is you see

try installing dead pixel from the market then check it that way. My is solid black, no bleeds at all.

This.
You can pretty much obsess over and examine any product long enough until the following realization occurs:
OMGDEFECTIEVE!!
It's really unfortunate that the OP cost the retailer/Samsung money going through a few phones for an obsessive compulsive microscope discovery about a real non-issue. Results in higher prices for everyone.
Ridiculous.

I think here's how you get to the bottom of this. Go online and google search absolute black. Save the 7th image on your phone. Then go to the saved image in your gallery and zoom in on the top left corner of the picture while in a completely dark room. If it looks weird, then your phone may have a problem, but if not, then STOP LOOKING FOR THINGS TO HATE.
This is a great phone, why try to ruin that. My guess is that the issue you're seeing is because of the camera. It's horrible in lowlight settings.

I don't have a GN yet so can't replicate your method, but if it happens when you use the camera app, don't you think it could have something to do with the camera? The camera gain will be all the way up in total darkness which will produce weird pixelations.
If you're trying to get solid black on the screen to evaluate the display, I am sure there's an app that can do that. Or simply make a web page with all black.

Hah!

Same thing with my gsalaxy s2. There are also other "strange" effects on gs2 screen at lowest levels. I think I saw something like that at note subforum. So I guess it is more or less normal for every amoled screen.
I can reproducethis issue, but I never experinced it in day to day usage. It is no problem for me.

Ok guys. Thanks for all the negative comments.
If your phone has no problem then good for you. I couldn't stand for this issue because I can notice it fairly easy in low brightness condition, I have tried to increase the brightness to around 40% and I can still see it. And again this is not a camera caused problem. I first noticed this when I was using Google Music to play some songs at night. The problem pretty much exists under any pure dark background.
Please look at the pic I posted, Does this look like "normal" to you guys if you were in my shoes?

This is an AMOLED issue. Just keep the screen step above minimum and its completely fine. Phone is not faulty, that's how that screen works. AMOLED is also more noisy on lower brightness, that's not a faulty screen.

I don't have this issue. My screen looks great and is from Expansys. What do I win? Your phone does look pretty bad though, maybe exchange it again?

Lower screen brightness with Screen Filter

The display hurts my eyes when I woke up in the middle of the night, even at the lowest brightness.
I found an app called Screen Filter that lowers the brightness even further. https://play.google.com/store/apps/...ch_result#?t=W251bGwsMSwxLDEsImNvbS5oYXhvciJd
Does anyone know if this is safe to use? Will it harm the AMOLED display at all?

It's funny, the lowest brightness is too bright for me when I need it, and the highest brightness is too dim for me when I need it.

I use Screen Filter on my original Galaxy S, and it works great.
I've never had an issue with it.

Been using screen filter on my Galaxy Nexus for months, great app. Now using on my Beautiful GS3.

Exactly my experience too. I love AMOLED's, but would it kill them to work on incorporating some Pixel Q technology. And really how hard can it be to just widen the range of brightness to capture the movie theater low if a stupid free app can do it?
There should be a huge range and we should be able to select the lowest and highest. Then let auto-bright take care of the rest. Or maybe even should have the ability to calibrate the auto-bright since a 20yr old's eye sees about double the amount of light of a 60yr old's eye...

Lux works much, MUCH better in my opinion

Try it, you will be sold! lol, im actually gonna go post about it, EVERYONE should know about it lol, after you set up 5-6 different ''levels'' and (imo) set it to adjust on screen open, its amazing

All it does is put a transparent black filter over the display. Not going to harm it. I had this app for my iPhone.

Thanks for sharing that. There are some apps that totally change the user experience. This seems like it will be one of them based on initial use. Too bad Samsung didn't calibrate this better out of the box.

can filter apps these make whites BRIGHTER and whiter? Whites are dim and yellow/pinkish next to LCDs. Very dim and dirty looking say on Google News or email.

ive been using this for a while as well. great for when in a movie lol! really handy

Exactly. Nothing to worry about. It won't harm your screen at all.
I've been using Screen Filter for a while now... but I may give that Lux a try. It looks pretty cool.

Should I worry about screen burn in?

I'm considering getting the S3 but Im worried about screen burn in. I'm the type of user who uses the lowest brightness possible. Should I worry?

I don't think burn ins are a concern with these screens. I left my screen on on a few separate occasions displaying a single image for over 7 hours each time with no problems so far.

I wouldn't worry. You need a still image to be up for an extrenuous amount of time. It is possible though, but you'd almost have to try. I haven't seen any posts with users with screen burn either.

Sent from my SAMSUNG-SGH-I747 using xda premium

Yeah, you never see much complaints about it but it's definitely possible. I'm going to guess it's less possible than previous version of the AMOLED displays. On my samsung infuse after 2 years of using the AOSP android keyboard, I could somewhat see an imprint of the keyboards keys whenever a dark-grey image is displayed on the whole screen but it was extremely minor.

You will get some burn-in with AMOLED after a few years no matter what. Pentile AMOLED (in the S1 and S3) is also superior to the AMOLED+ in the S2 for longevity, or so says Samsung.
My 2-year old Captivate has some up top where the notification bar is, and on the bottom where the keyboard is, and where the high-contrast black&white WordFeud game tiles are that I always play.
The burn-in ghosting isn't THAT noticeable, though, unless you're viewing mostly white images or webpages.

S3 do have burn ins just to let you know. Download screen filter and lower the filter to 10% or maybe 0% and you will see imprints. or download dead pixel test and the second color will show also all your burn in.

[Q] Possible to make the screen brighter?

I'm not sure if I'm the only one, but I find the Galaxy S III's screen to be terribly dim in sunlight. Poking around the internet, I found that Samsung manually cut down the maximum display power, nearly halving it from the S II.
The Galaxy S III uses a 1280-by-720, PenTile AMOLED screen, which is higher resolution, but dimmer than the Galaxy S I and Galaxy S II screens, Soneira said. The culprit seems to be power management: in trying to get decent battery life with a huge 4.8-inch display, Samsung had to turn the brightness down.
Power consumption figures bear that out. Samsung cut maximum display power from 2.1 watts on the Galaxy S II to 1.3 watts on the Galaxy S III, dropping maximum brightness from 289 candelas per square meter to 224. The lower power usage, however, lets the S III get solid battery life even with the larger screen: running time with the display on increased from 4.4 hours on the Galaxy S II to 5.6 hours on the S III.

My question is if it's possible to manually increase the display power, since in my understanding it's being artificially lowered? Like similar to under-clocking or something? Sorry, I'm not really that tech knowledgeable.
