hi guys,
my o2 xda does not seem very bright, in my old ipaq there were brightness settings, i cant seem to find these on my uk xda.
any tips chaps?
no chance
I have followed some tips about registry editing for the XDA. The does provide the utility for changing brightness on pocketpc. Although the XDA does not appear to support variable brightness.
The setting I enabled was a fully functional slide bar. But the various settings had no effect. The XDA supports only on or off. If any body else has had more luck then please post your results and tips
You are right, the iPaq has a multilevel backlight that is linked to an automatic sensor that detects ambient light levels.
The XDA just has two settings, on and off.
The iPaq 3600, 3700 + 3800 screens seem about the same, with not a great deal of visable difference in brightness, however the new 5400 (etc) are quite a bit brighter.
The XDA is more that adequate for what i need.
Hi
You mentioned the xda is not too bright. It only operates on full brightness, and it seems pretty bright to me.
Perhaps there is something wrong with your unit. Go back to the shop and compare with another one. Get it changed if its faulty

Is there any way to increase the backlight further, because screen is not bright enough even when set to max. Maybe some registry hacks?..
I think this is possible, because if you guys had noticed, that when you start the 'Camera' app, the brightness increases a bit even when it was already set to max.
Even my previous Nokia 3100's screen is brighter (shame), so any suggestions would be appreciated. Thnx in advance..
Well, can't anyone help me?? (Even the experts??)
It's probably not possible to make it brighter. I think what you see with the camera is an illusion because it changes the LCD contrast/bright level, not the backlight level. It's not logical to think that the backlight is purposely limited to be less bright than it truly is.
That may be why there are no responses.
Well actually there's a response, since you're using the WM2003-SE it will decrease the brightness as I noticed from several flashing and I'm very aware of that and sensitive about this case. Further more, from couple minutes when I downgraded from 1.72.00 to version 1.66.00 WWE, it decreased as well, so if you flash back to 1.72.00 you'll notice the screen is much brighter than the WM2003 SE and the 1.66.00, I want to add something else. HTC released two type of Himalaya which is different in the Screen type and the flat cable socket. New releases are brighter than the predecessors.
a quick reply, adjusting brightness will also decreases the battery.
a big big diff.
so I returned my sgs2 today and got a new one (old one had scratches). Now it seems to me that there is some flickering with black lines (very faded) on certain brightess settings on mainly white sites using a browser.
I noticed the flickering appears around 16% - 19% brightness settings (using "brightness level" from the market).
This flickering only appears only if "auto adjust screen power" is NOT selected, same brightness with it activated shows no flickering.
Also last but not least if plugged in with USB cable the flickering stops as well.
Can anyone re-produce this flickering?
1. Download "brightness level" from market, go between 16% - 19% (try step by step), with me its strongest at 17%.
2. Ensure "auto adjust screen power" is deactivated under Settings>Display
3. Open Internet and just look at a mostly white page
4. Ensure USB is not connected.
Can you see some slight flickering? Lots of lines across the screen?
Wonder if its just me, might go back and return this one tomorrow then
I assume no one suffers from this issue?

No flickering.
I get black/dim horizontal lines flickering on the display at low brightness regardless of my "auto adjust screen power" setting. I'd describe it more as a shimmering of the screen. It's very distracting - I first noticed it whilst trying out the Kindle app and it made it very difficult reading the text.
I believe it's down to interference with some radio component of the phone. I've searched various forums and haven't come across many mentions of this so maybe it's a bad batch and I'm considering returning mine. It's frustratingly variable so I hope I can demonstrate the fault in store...
I'm wondering if the increase in brightness just masks the effect rather than eliminating it. At lower brightness settings, any local differences in brightness are going to be more noticeable.

have you noticed any change at certain battery levels?? Like if the battery was at 90% its easily noticeable, once its like below 70% I'm not able to re-produce it, no matter what I try down to 0%.
So maybe since it seems to be only from 90% - 70%, it could be to do with the current/voltage at certain brightness levels with white background...very unique problem it seems..I'm thinking of going to the o2 store but I most likely wont be able to re-produce it then and there so will they still exchange it? hmmm lets see..

I'll note down what the battery power levels are over the next week or so.
I went into the O2 store after work and reproducing the effect was indeed difficult. I had it showing the effect in the shopping centre whilst sitting down at a bench. I had it showing the effect whilst in the queue to wait for an O2 staff member. Fifteen minutes later, once I'd got to talking to the staff, it worked fine. All I could do was explain the problem and ask if anyone else had reported it. They advised I "kept an eye on it over the next couple of weeks".
Really frustrating. I'd entertain the possibility that my eyes are faulty but I've shown the effect to someone else and they agreed it was distracting.

Hi,
I was not able to reproduce it using your directions, but I have to say that I also noticed horizontal lines flickering on white.
I tried to reproduce it but I can't find out what it is related to.
So it's doig it just in random fashion

does it flicker with auto brightness on? You might want to download an app like "brightness level" and set it to different settings to see when/where it flickers...mine usually flickered at 17% screenbrightness when battery was at 70 - 90%

Yes I did download it and followed yur directions to try to repruce it. But I could not. I set then brightness to various level from 100% down to 0, but no luck. I have to try now when battery is at that level. Then it could be some kind of intereference. Lines I noticed on mine are very subtle and close about 1 mm
Ok, confirmed: 92% battery, brightness 17% on white or close to white screen color, there are horizontal lines like some itnerefernce/noise. Annoying
Samsung galaxy S2 screen flickering
I also have the same screen flickering problem.
it happens when the battery level is around 87-91%
Any soulution?
same here
black lines around text on white background. It disappears after a while, but is really annoying. I suppose the only solution is to change the phone?
sorry guys to hear u got the same problem....I never found a resolution to it apart from returning it to the store....once I managed to reproduce the issue infront of the manager he swapped the phone straight away.
If you got the same issue make sure you get to the store with the battery level and brightness level that shows it up, ask to go into a dark area to show it properly.
First o2 store I went to the guy refused to look at it properly and as it was light outside he couldnt see it anyways. Second o2 store I went to, the manager went downstairs with me and turned off the lights to see the flickering because it shows only on low brightness so make sure you take that into consideration when in a bright/well-lit store.
i have the same problem, it, but it only appears when "auto adjust screen power" is on. Its really a shame! Only way to fix it is to change the phone?
same here. flickers at low brightness with battery under 90%. called samsung hotline. the problem was new to them and the only idea they had was resetting the phone. tried it but unsurprisingly its no help. galaxy s2 could be great but it has just too many annoying hardware flaws
Same problem
Well I noticed this on my SGS 1 !! ... when I have PACKET DATA turned on this flickering starts. It starts really hard when i have this function turned on, but when i disable it there's nothing...
Noticed same problem on SG2 bought in Sweden
Realise this is an older topic but i have recently noticed this issue in low light with Auto On. Battery level at 85 percent. For those that had their phones replaced did the issue continue? Has anyone seen this with the yellow tint also?
Noticing this issue as well on Villain ROM 2.4. Auto brightness enabled and 90% battery.
*Edit* Just did a CWM restore to stock rooted and the flickering seems to have gone. 85% battery, auto brightness enabled.
phone swapped... problem kept
i got my phone replaced 2 months ago and was very happy with the new one since it had no screen flicker... until now. so my current sgs 2 now also suffers from screen flicker and my only options are to send it to samsung and hope to get a replacement or to live with it. and since im beginning to think that this might be a general problem i tend to keep it. although i have to admit that i dont like my sgs2 as much as i did before...
I've done a search and it produced no results at least nothing relevant.
I'm wondering what people are using for their custom Light Levels in CM7.
Auto typically, but in my office I find it too dark... so I use 40%. I've got brightness (all of them) in the notification dropdown.... removed bluetooth and gps (pointless).
I have not done any of the screen rendering...
That's the same issue that I've had as well. I suppose it's partially due to my eyes being so accustom to the bright colors from the standard 2.2 ROMs. I'll look at tweaking it a bit. I don't mind the screen not being as bright as it was before, but it stays rather dim and becomes slightly hard to read at times.
Ok i wanted to start new thread with this issue
got a question about the screen. Some times I can sense and see that despite of auto brightness off that the screen adjusts its brightness by itself. It is a little change but my sharp eyes can see this... Do you have a similar thing?
I can easly notice this when playing my country game. When I click on the building menu the screen gets brighter. When i cancel the menu the screen makes darker
Also in sprinkle when I use water the screen gets little brighter
I think this is because the Tegra 3 (or ASUS's implementation of it) adjusts contrast to conserve power. The changes in contrast make brightness seem to change.
I think their settings are too aggressive and they should either scale them back or add an option to turn it off, if possible. I'm sure it's nice for battery life but it does (in some very specific instances) seem to impact the experience.
Note: this is not a doom-and-gloom post. The Prime's screen performance is the best I've ever experienced on a mobile device, maybe any device, overall. So this is a bit of a nuisance but nowhere near enough for me to have an inkling of regret about buying the Prime.
This only happens on mine while in power saving mode.

I'm not sure, I'll have to do some more testing. I seem to remember it happening across the board.
I'll note that Battery mode really does make a HUGE difference in the screen's performance. Colors become very washed out, so much so that I'm really surprised by the impact.
Well in my case this thing occurs on every mode with the same strenght... That sucks
so anyone of you can confirm if this is normal? Do you have the same isue on your primes?
It seems the light sensor has high resolution and Asus needs to smooth up a bit the auto-brightness algorithms If your screen goes up and down then simply disable auto-brightness or change lightning conditions

Like i said auto brightness is off. Can anyone install my country and check his out for me? Just enter build menu and chec if the screen gets a little brighter
it has nothing to do with auto-brightness... Its a feature of tegra 3, it can change the brightness of each pixel to give you the best image and use the least amount of power.. unfortunately its just annoying and not implemented well.
And you cannot turn it off.
Ya I noticed this too last night and thought that I had a defective screen. Made a thread about it earlier. http://forum.xda-developers.com/showthread.php?t=1421002

I should b off in perormnce mode. I understand this feature in saving power mode but not on others two. I hope it will be changed
Hi.
I own a Samsung Galaxy S2 I9100 and I love it.
However until today i had never encountered this "problem" in my phone.
My friend has a Galaxy S2 too, and today while I was helping him something with his phone, I noticed his screen brightness was higher.
We both have Android 4.1.2 Jelly Bean XXLS8 running.
I also checked in the Settings under Display, and we both were on Dynamic Screen Mode and on full brightness. Auto brightness was off too.
just for the sake of it I also checked if the Power Saving feature was off, and it was OFF at both phones.
i typed the *#0*# and compared the colors of both phones and his phone clearly was brighter.
Unfortunately I couldn't take pictures of both phones or even do a video, but I hope I will do it soon, depending on the responses i get from you.
Any help would be appreciated.
BUMP: Just in case.
I think it's allowed to bump after 24 hours of inactivity. If not, than Im sorry.
Are there a screen related application or some custom kernel tweaks active ? Fox example with "Screen Adjuster" app you can change the 100% level (notificartion area slider) to be something else in real life.
There are no tweaks on either phone.
just for the sake of it I installed the Screen Adjuster app to see if my screen brightness was actually set to 100% and it was. But still his screen brightness remains brighter.
I hope u r not using any privacy or matt finish screen guard ?

Maybe you both can email Samsung and bore them with this story.....zzzzzzzzzzzzz
There are two possible explanations to this:
1) Not every device is the same because the factory has several versions for their parts and the part will work the same, but there are subtle dufferences in performance. This is called "part revision".
2) Did you or your friend replaced the display on the phone? The service center could have installed non-Samsung OEM display that performs differently than the genuine one. Not speaking about OEM fake gorilla glass....
