dk206 - from the pics you posted it seems like the left half of your screen is darker/slightly different colour than the rest of the screen, is it just my imagination or you can confirm it?

Asking because I posted about this problem, which I'm having with my SGS2.
[Galaxy S II General] dk206:
Thanks. Yes you're right guys photos don't do any justice. You guys need to come see it. The guy at the CPW saw it straight away and told me to queue up for a replacement but non in cpw in central london now. All sold out. They put my visit on the system so I don't have to explain and waste my time next time I pop in for thr replacement. But I haven't dexided whether to go now or go when NFC sgsII arrives which hopefully will be in 2weeks time? :s
[Galaxy S II General] dk206:
Yes about 1/3rd of the strip on the left hand side is darker than the rest I have 4lines but the one splitting gpss & sound is the most obvious to tell. I compared it to the one they had in cpw om the floor. It did now have those lines running down. Can you guys take shots of your notification screen please and post it on here?
[Galaxy S II General] erazer007:
@dk206, mate this worries me much. I actually purchased a GS II from CPW in UL itself. Although I still dont have it with me. My friend has it and he will bring it when he comes along to Bahrain where I am currently staying. I got it from the UK since its going to release late here. Maybe I should ask him to take a proper look in case it needs to get replaced. The second set of pictures shows the problem. What about in darker colours-not black say dark blue or dark green. how does it show then? And what about doing the screen test?

Thanks
[Galaxy S II General] d3sm0nd:
Sadly I also have two very small dots... If on full brightness I can't see them, but on low they are noticeable.. I don't know if I should request a replacement?
[Galaxy S II General] OHDUSER:
got no issues whatsoever o.o

its good I have got no issues.. I live like 1500 miles away from where I got this phone.. returning it would be quite problematic...
[Galaxy S II General] dk206:
Sorry to get you guys all paranoid lol.

On the screen testing its harldy noticeable. However everything else even on this xda app now I can see the lines running down. So definitely not. A software problem. When I'm watching a movie e.g FF 7 advent children mkv file at night with all the lights jn my room out I can definitely see the yellowish lines going across my screen on landscape mode...

Does anyone know when NFC enabled sgsII will be coming out for CPW in the U.K?
[Galaxy S II General] r_a_c:
Do you also mean the 1/3 of the the screen that is a little bit more dark/yellowish, not really a line, but just that part of the screen as you can see on the 2nd part of pics you took.

I have it too, but it's not that noticable, it's more like on you your 1st pics.

Do you think this is a problem too? Don't have the lines tho, i guess.
[Galaxy S II General] Seabass1:
On mine the left third of the screen is slightly darker and has a yellow tint, but there are no lines running down it. I'm in two minds as to whether to get it replaced as it's not all that bad and there is no guarantee that the replacement would be any better.

As for the NFC enabled version I've seen lots of conflicting reports, but June seems to come up more often than not. So you might be lucky in that regard.
[Galaxy S II General] r_a_c:
Mine has that too, yellow tint and little darker... I think most of us have it? Would be nice if people could check it.

Could you also check my topic, named "different screens?? Or what is this?"

Abouth the blue-ish shine. Read abouth it there;)!
[Galaxy S II General] dk206:
Yeah just read your post. Dont have another sgsII to compare but comparing to sgs my sgsII is white as gandalfs beard. Sgs is soooo blue compared to the sgsII
[Galaxy S II General] erazer007:
Damn. Lots of problems with the screen are being reported and I dont have mine iwh me to check it out.
[Galaxy S II General] BlueScreenJunky:
Screens are never perfect, I think we have to live with it.

On the last 7 screen I had (almost all from samsung mind you ^^) every one of them had small problems :

-Samsung 970 P : Had severe reverse ghosting and some backlight bleeding.

-Samsung 2233BW : reverse ghosting and even more backlight bleeding

-A 72cm Samsung CRT TV : geometry was awful (vertical lines weren't straight at all, plus the first) and part of the screen was pink. I had it replaced and the next one still had awful geometry and was slightly yellow on one side.

-Samsung 2233RZ : there's a darker band in the middle of the screen.

-Panasonic 42V10 (42" plasma) : green trails and some mosquito noise.

-Samsung T220 : Backlight bleeding.

-Nexus One (AMOLED) : when you had black text on a bright background, each line of text made a darker horizontal band on the whole width of the screen.

So now when I buy a screen I don't even try to find defects, I know there will be some, but if they don't bother me right away I consider the screen is good enough.
[Galaxy S II General] r_a_c:
Allright i just put it to the test. I went into a complete dark room, maximum birghtness on and yes i saw white vertical lines. I even saw horizontal ones. But i think it's more of some hardware shinning true, possible?

Than i opened a grey picture from google, this one:http://www.tamilkey.info/?attachment_id=1152.

Showed it pretty good!

Could you check if you also see come kind of pattern in the lines, i did.
[Galaxy S II General] Seabass1:
I just tried that and I can see very fine horizontal and vertical white lines, but that's just the pixel structure becoming visible I believe.
[Galaxy S II General] Erethnor:
I personally disagree with this - my reasoning being that if anybody pays 500£ (or more) for a phone, the screen had better be perfect (previously owned a HTC touch HD and the screen did not have any problem whatsoever).

I bought my SGS2 from amazon.co.uk and they suggested calling samsung before returning the product, which is what I am going to do tomorrow.

Curious to hear if it's a known problem, and how long it'd take to have a replacement.
[Galaxy S II General] dk206:
Yes the 1/3 of the screen (left hand side) is a bit darker than the other 2/3rds.

I think you should rac. I'm getting mine replaced on thursday this week. Already arranged with CPW in Oxford Street.

I compared it to the one they had on the floor demo. And that screen was immaculate. I compared it properly. 0% brightness going up 10% each time to 100% on both. That screen was perfect. Before I leave CPW on thursday I'm going to make sure I get the real deal.
[Galaxy S II General] f1ux:
Mine also has a small patch where the pixels are lighter than the rest but it doesn't bother me unless I look for it.

Standard lcds have uneven backlight, oled has uneven pixels. That's life I guess!
[Galaxy S II General] LawAce:
Seeing as this screen is supposed to be a real killer, it had better be nothing short of perfect IMO.
[Galaxy S II General] dk206:
The screen is superb. Normal people won't be able to notice this at all. Unless they've actually gone out of their way and did screen tests. I have a good eye so I noticed it.

The real lol problem is that now I know it is there, I can't help not notice it. >.<
[Galaxy S II General] Bawezy:
I too have horizontal patches going along the screen, reading this thread made it a bit more obvious now lol.

As a lot of you mentioned it's only visible when the brightness is turned all the way down.

Edit: Try running this and see if it temporarily fixes it flexcode.org/lcd2.html
[Galaxy S II General] conundrum89:
That won't fix these issues Bawezy, that's to fix a specific problem that can arise with LCDs. Since AMOLED is a completely different technology, trying to "unstick" the pixels won't do anything.
[Galaxy S II General] dk206:
Getting my phone replaced today.

:O
[Galaxy S II General] hazart:
Hope the screen will look perfect!
[Galaxy S II General] bandoo:
I had a problem with the screen too, bottom right corner there was a burnt in ring the size of a penny only noticed it when i took the full brightness down.

Sent mine back to CPW and got a new one which did'nt have the problem.
[Galaxy S II General] dk206:
Update

UPDATE: Called CPW this morning. They say they still do not have SGS II in any stores in central London. The guy said it might take upto a month for new batch to come through. I asked about NFC and the guy said he wasn't sure. He said however it was weird because they now haven't had the SGS II in stock in any of their warehouses for over 2 weeks and Samsung have still not replied to their demands in London.

Maybe NFC is finally going to come soon. I might be a lucky guy ;)
[Galaxy S II General] AngelAbaddon:
I had exactly this issue on my P4U S2, posted on here about a week and a half ago. Anything with a white screen (Twitter, Facebook, Reader) made it completely obvious. Got it swapped over and the new one is fine. Guessing it was a dodgy batch of screens maybe?
[Galaxy S II General] Monty Burns:
And the law is on your side. The Sales of Goods act specificaly says "free from MINOR defect" of which even ONE dead pixel is a minor defect. Its irrelevant what the retailer trys to get away with or even the manufacturer saying "we accept 3 dead pixels".... all BS under UK law.

The law also states that you can by all means, contact Samsung BUT you return it to the retailer and NOT Samsung. Its the retailers job to fix, replace or refund.

When I was in school we were taught the UK Sales of Goods act, sadly, I don't think its been taught for years.... which is why many people get fobbed off with "return it to Samsung".

Also, a device should last as long as is reasonably expected. If you buy a phone on a 2 year contract, it should be reasonable to expect it to last 2 years... if it goes wrong, f**k warranties, return it to the RETAILER where you signed up for the contract.

Of course this all according to UK law. Everytime I bring this up I get European mainlanders trying to argue and tell me i'm wrong despite the links I can provide to .gov.uk etc. I wonder if this time it will be diferent?
[Galaxy S II General] trs020382:
Must be a bad batch...

As for CPW, I tried to get a GS2 on Monday from the Trafford Centre, and got the last on in stock anywhere in there (I went in EVERY phone shop on Monday night). CPW had one in stock in every shop in the area, which were just demo's, and just 7 in the warehouse in Wednesbury, which covers a pretty large area.

Popular handset much?

Anyway, back to my point, if it was a bad batch, then chances are, these will all have gone through the "system" by now, and a new shiny fresh batch with no screen issues will probably be coming...
[Galaxy S II General] dk206:
with NFC (hopefully for CPW too)

Because when I went into Orange they confirmed that NFC enabled SGS II will be arriving in 2 weeks time.
[Galaxy S II General] drleospaceman:
They're pretty much all like that in low brightness (ymmv). It goes away with higher brightness.
[Acer Iconia A500] docfreed:
There are some apps that need run full-screen and I am finding that the status bar interferes? Example, Softick Klondike Solitaire - unfortunately a great game but the developer put the score line so that it's hidden by the HoneyComb status bar. So I'd like to hide the status bar - there may be other apps that need this too
[Acer Iconia A500] z4gnom:
hide system bar

I have same question - I need to develop application for internal use, but without native 3.0 navigation (back, home, apps at system bar). One way I found - set ro.sf.lcd_density to 240, system think that this is mobile phone and change interface to show top status bar without any system bar, and status bar can be removed in program, but in this case I have to rebuild program layouts and this solution is not very good for other applications.

It look like system bar placed very deep inside android 3.0 code, so now I even thinking about porting android 2.3 to Iconia A500.

Any ideas?

[Acer Iconia A500] rushless:
Unless 3.1 or another update provides a solution, Honeycomb is stuck with it, which is lame for for a few reasons:

Easy to touch by mistake, and is no different than having a smaller display, since the space is taken by it. At least iOS gets this right and does not take up space. One of the few things they DID get this right.
[Acer Iconia A500] z4gnom:
just realized that system bar can be removed by killing systemUI service, this service is hidden in "running", but can be found in "all" and can be easily stopped.

now looking for program solution to kill it and restore by me application
[Acer Iconia A500] hawkeye2188:
I know there is a setting in Launcher Pro that you can hide it on phones, I dont know if it will work with this though.
[Acer Iconia A500] cybermage1:
Guys keep in mind this becomes less of an issue if you can get developers to update their apps for the Honeycomb SDK. There's a mode they call "lights out" that causes the system bar to dim tremendously - which is what the youtube app does.

Maybe instead of killing it, a third party app that causes it to go to dim mode and stay there - kind of a toggle - would be more appropriate so you don't lose the use of the buttons.

http://stackoverflow.com/questions/...-lights-out-mode-in-honeycomb/5097719#5097719
[Acer Iconia A500] rushless:
The brightness is not the issue, but the space the black bar takes up is. Kind of like the old CRT days when the bezel was quoted as part of the screen size. For 3.1 users, a 10.1" display is really 9.6, since space is taken up by the bar.

I went back to using my gTablet for now and notice that I have more display (though a display with awful angles).

Call me stupid, but I would prefer Gingerbread on the A500:

1. Games would work fine

2. Display resolution not compromised

3. Flash works fine

4. Less issues with legacy apps and Tiger Arcade has no scaling issues.

5. Actually, no apps have scaling issues with Gingerbread, but a lot do with Honeycomb, so need to wait/hope the devs update.

Yes, defeats the purpose of the tablet centric OS, but the bar at the bottom is a waste of display space.
[Acer Iconia A500] moonzbabysh:
"Honeycomb has a hidden Gingerbread (Android 2.3) UI within it.

And it can be very easily unhidden by simply changing the LCD density. Set it to 170 or higher, reboot, and you'll see all the graphical elements of Gingerbread (lock screen, dock, app drawer, keyboard, etc.); set it to 160 or lower and the Honeycomb you're used to will greet you after a reboot."
[Acer Iconia A500] minotauri:
the status bar has the soft keys... trust me, its nice to have since there are no hard keys for this device. this was a feature that was implemented for nook color in cyanogenmod because the lack of hard keys and it made all the difference. how are you going to press back or menu if you don't have that status bar? sure you could use the softkeys app or button savior but they are inconvienient and also put stuff on your screen.
[Acer Iconia A500] z4gnom:
com.android.systemui

I tested some ways to kill system bar:

1. Kill by adb shell: - su; ps, look for com.android.systemui; kill <PID> - success, sys-bar removed.

2. Settings, "Sytem UI" force stop - success, sys-bar removed.

3. Root explorer, delete /system/app/systemui.apk - got circle of error messages "com.android.systemui crashed, blabla...". Reboot, tablet started without system bar, no any errors, so success.

4. My app:

android.os.Process.killProcess(android.os.Process.getUidForName("com.android.systemui"));

failed, as expected, because my app can not kill process started by another app.

5. My app:

permission - android.permission.KILL_BACKGROUND_PROCESSES

final Context context = getApplicationContext();
servMng = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
servMng.killBackgroundProcesses("com.android.systemui");

Failed, no idea why.

6. Run script in my app to execute "ps", look for PID and execute "kill", not tested.

I need to implement option 5 or 6, can anyone give me some hints why 5 failed (or how to perform 6)?

Also I need to restore system bar using my app, I tested "am start blabla", it work in some cases throwing some errors and do not work in other cases depending on moon state, I do not know exact parameters for "am", also best solution to run in from app using java, any ideas how to do it "correctly"?
[Acer Iconia A500] brunes:
Lights Out mode

Part of the honeycomb API is a Lights out mode that dims the status bar so much that you can hardly see it. If you want to see it in action, just open the Kindle app.

Until 3rd parties update their full screen apps with this API, it would be nice for a third party app to implement it.

Greetings from XOOM land. :)

I was brainstorming a way to hide the status bar and bring it out again when needed. It seems Windows 8 will do just that, and will use the same method I had in mind.

The idea is to use a multitouch gesture to hide it and bring it back. Touch the screen with two fingers and swipe off of the bottom of the tablet screen as if flicking the status bar away, and it kills it. Swipe up from off the screen to bring it back.

Now, implementing this would be difficult, at least for me, but I think it would be awesome to get the bar out of the way sometimes.

[Acer Iconia A500] Dan2552:
Non-programatically you can kill it in Settings under manage applications, System UI.

Therefore, would it be posible to launch this settings page, send a couple of virtual D-PAD key presses to select the force quit button, and then Return key presses to press the button. Is this possible, using a persistant IME perhaps?

[Acer Iconia A500] Dan2552:
Okay, that's useful for rooted devices. Thanks for sharing.

My question still stands for a non-root solution though, if anybody wants to try or knows whether or not you can do that.

If you use an on-screen dpad (e.g. TalkBack's IME) you can at least get as far as the ["Force stop" OK/Cancel] popup window so a custom IME should at least be able to do the same with key presses at timings, not sure if it'd then be able to press OK for you though.

Obviously this method would be a bit of a mess onscreen visually while it runs, but at least if the IME view takes the whole screen it should block all input (except the bottom bar i guess...) during the process.

I know this is a recently revived old thread but if any non-devs are looking to hide the status bar there's a paid app called Honeybar. Requires root.

Disable The status Bar

I'm hearing a lot about "hiding the status bar," and obviously, we cannot do that without rooting our devices. The my question is: can we disable its effect? I want to make a lock screen, and in ICS and Honeycomb devices, that status bar ruins it. I can apply the "darken" version, but can I disable those buttons too, to prevent the user from going around a secured lock screen? Some apps block the "back" and "home" buttons, but what about the settings, recent apps, and notification buttons? Is any of this possible (without rooting)?
[Acer Iconia A500] haag498:
Well, the default lock screen does it, so I suppose it's possible -- you can't use the soft buttons, all you get is the clock and notification icons (no interaction possible, though)... but as the HC Source isn't public, I don't know how to do it... I'm not going to dig through tons of binary code.
[Acer Iconia A500] metpolds:
+1 on that!

If all you want to do is hide the status bar during games etc, and yet be able to put it back, either way with just a "tap" on the screen then you can't beat the app "HoneyBar". It does what you want without jumping through hoops or writing scripts. Yes I know it needs Root but who these days is writing apps or considering major modifications to the presentation of the o/s without being rooted?
[Acer Iconia A500] mhsamma:

Hey everyone,

I'm an X G2x user, and over there in "G2x" land I rooted my phone first.

Then I flashed Clockwork recovery on it

THEN I had a smorgishboard selection of "Roms" to put on my phone.

Here's where i'm confused with the Galaxy S 2, and Terminology really..

What "do we have" here with the SGS2 so far?

Just rooting it? I see over on the dev section people talking about all these kernels... what is that? are they like Roms? Has anyone mad a rom? can we flash it like clockwork mod recovery?

Just a little confused with the differences in terminology and procedures over here on the samsung side.. thanks

No custom roms yet, no CWM either. Just kernels and root....the kernel is a bridge between applications and hardware basically. Terminology shouldn't be that much different really.
