SGS 2 Light leakage - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I have noticed some light leaking from the right side of the home button. It's a small light leak but was wondering if anyone has this issue .

I also have this issue, but I can only notice it in a dark room. Still a bit annoying though.

Can someone post a pic? Just to know what to look for.

I noticed as well earlier today. No biggie though, only a small annoyance.

??? There is no backlight in the phone, what is there to leak?

They are talking about the backlight on the back-button, which if you hold the phone in a certain angle in a dark room you can see some through a gap in the home-button.

It's not a "leak" , it's the phone itself.The parts under there fit such that there's a small hole in that spot and light seems to "leak" ( and it can only be seen if you angle the phone a certain way ) . Don't think it's a big deal.

I have it too....... but it'snot really annoying.......viewed only in certain angles in a dark room

Yes it is there and mine is a little worse than my dad's phone. I've dismantled my phone. The usb PCB lies on top of the button. Unfortunately the button is sandwiched in between the lcd panel and the middle frame. I've been trying to find a way to kill the light but haven't figure out how is the light leaking out. Usually on a blackberry's keyboard it is because of the paint on the button being scraped off a little but it probably isn't the case on the phone.

I noticed it on my phone one night too. It's barely noticeable and only if you look from a certain angle. Can't say i'm bothered by this.

You seriously dismantled your phone because a bit of light leaks from the home button? Is it stopping your phone from working or something?
Madness.

I can't dismantle my phone to fix issues?
I've dismantled my $2000+ TV to fix backlight issue, dismantled my whole car's interior to fix rattling issue, I've dismantled my $1000+ dac to fix soldering issue, I don't remember what else I've dismantled but I surely dismantled and fixed a lot of issue. What's the big deal with dismantling my Galaxy S2? Some guy on youtube posted a very helpful video on dismantling an S2 but all he got was silly trolls flaming him. The same happened to people who dismantled their brand new iphone.

light bleed for tbolt?

just wondering if anyone else is also tolerating the unfortunate light bleeding around the bottom half of their phone and above the soft keys. is this an issue with most of the thunderbolts or did i just get a defective model?
Can't really see what your talking about, is it like that for you all the time for you?
Sent from my ADR6400L using XDA App
I only see it when tilting the phone down at an awkward unusable angle. Don't see anything anytime i've been using the phone normally.
found this http://forum.xda-developers.com/showthread.php?p=12954063&highlight=light+bleed#post12954063 .
My phone has that too, but it really never gets in the way unless like said you're looking at your phone from an already unusable angle.
It's a problem with most thunderbolts and many phones/tablets in general (even the jesuspad isnt immune).
As already mentioned, I dont ever see it unless im intentionally trying to look for it (at an angle).
Have same issue at an extreme angle.
Have same issue only a problem at night. Daytime I don't notice a thing.

like stated in the link posted above, its from the illuminated capacitive buttons at the bottom and not the LCD panel itself.
On my first thunderbolt, i actually had the entire screen rotated by a few degrees and pretty bad bleed from the back lighting of the keys at the bottom. VW overnighted me a new phone and the new one still has the back light bleeding, but as others have said, only at extreme angles.
The screen isn't bleeding. It's just the lighting from the soft keys. I only notice it when I have the phone at a certain angle. No big deal.
This normally happens with any device that has backlight keys, soft or not. My Droid X did the same thing.
i work for verizon and every thunderbolt i've sold hasn't had nearly as much light bleeding as mine. it is a painful thing to sell models that surpass mine haha, getting a new one sent to me though, just hope it's not the same. blast this ocd

Screen light leakage from leds

So I have my rezound now and so far setting it up and putting through it's paces and only one thing has me a little miffed and that the leds that light up the capacitive buttons below the screen are leaking up when you change the viewing angle slightly.
It's something I can live with but if I have a dud I'd like a replacement. My incredible s didn't have this issue.
Thanks
Sent from my HTC Rezound using XDA App
Mine does the same thing(so did the one on display at my local Verizon).
It's a bit extreme, but if you open it up, separate the screen from the digitizer, you could put a thin strip of electrical tape in there and that should block out most of it.
I'm not going to go to that extreme but pretty lame that they couldn't fix that.
I wonder if all of these major issues came from the same batch of phones. Mine hasn't had any of the problems, no audio issue, no bootloop, no heat, no light leaking, no dead pixels. When my buddy gets his today I am going to see if he has any issues.
Are you taking about seeing light when you look down on the phone from the top?
To illustrate what I mean..
Lay your phone flat on its back, then stand it so that it the screen is perpendicular to the surface. Now look down on the phone as if you were trying to look into the headphone jack , but direct your eyes to the led soft lights . You should be able to see light.
Make sure the LEDs are on of course.
I'd this is what you mean.. I don't see it as a problem. More like nit picking. We don't use the phone at that viewing angle for anything

I've owned 2 HTC phones in the past and they both have had light leakage.
I'm learning that some things on phones we just have to accept, because really they aren't that big of a deal
Light leakage on HTC phones is one of them, the other being issues with sAmoled screens such as tint problems. I guess some things are just manufacturing artifacts. Sure they can completely get rid of light leakage, but whatever you won't notice it in a couple weeks anyway. It isn't a defect, just something common with HTC phones.

What hardware issues are you experiencing?

There seems to be a number of people raising certain hardware issue problems. I don't know about you, however I don't seem to have any issues at all here.
Current Issues
Light Bleed
Back Cover Flex
Warped Back
No issues here!
Vote in the poll!
Would be nice to know which possible batch you got yours from.
Did you order it on launch day or have you ordered it since it's come back into stock?
Which country have you ordered it from?
Have you had to RMA ones before?
I have no issues at all. There is a minor amount of light bleed around the bottom edge (landscape with camera at top)but this is no issue as it only affects the nav bar, and is totally invisible when set to lowest brightness setting where I tend to use the tablet . I love this thing.
If I turn the brightness up full, I have the weeniest bit of light bleed on the bottom right corner but you have to look hard to see it.
Everything else is fine
Possible Touchscreen/Multi-Touch issue?
Still awaiting for others to leave some feedback Only takes about a minute or two to test
Some of these are not a hardware issue but a chassis issue. Hardware is the components inside the tablet.
I ordered on the 13th and no issues to report.

Minor technicality.
Minor light bleed, non factor. Extremely pleased with this tab!
Minor light bleed in lower right like everyone else, which I wouldn't have noticed if not for reading the forums!
My LED is not working, our art last I can't make it work. Doesn't really bother me as in my previous tablet (a BlackBerry playbook) I turned out off anyway.

Nothing at all there could possibly be light bleed, but I have not dine a test, I am just using it and in terms if uses, there is nothing noticeable

So far as I'm concerned, hardware is anything physical, so to me the chassis falls under this. Hardware is physical components, software is well, software.
Part of the 2nd batch (restocked 11/20).
Only minor light bleed.
Alright I ordered another one due to some light bleed that is visible on almost all automatic brightness levels. I sure hope I don't get one that's worse. charging cable I got doesn't work either so that also pushed me to RMA it.
Sometimes when holding the Nexus 10 with one hand on either side, I frightening notice the side speakers slightly detach. I only noticed this three times before I promptly adjusted the way I hold it till I get a case with sufficient protection.

Light bleed. And not a hardware issue but a lot of freezing....

I haven't seen anyone else mention this anywhere, but the backlight makes a really annoying high-pitched whine whenever it's turned on, and the pitch/tone changes with brightness. From what I've read it could be a choke coil squealing but I didn't think something like this would have them large enough to make noise.

I maxed out my brightness and I couldn't hear a thing, however I did notice that my plasma makes a high pitched whine.
Multi touch all good here when using the app that was posted; tried several different touches to be sure.
Light bleed in the bottom right, pretty minor though. Everything else is solid & working though.
As for the back strip flexing, The clips that keep it secured are tiny, so it doesn't surprise me that that is an issue for some... makes me wonder how things will go once the covers that swap out the back strip are released...

Light bleed, but the most annoying one is that the front and back camera both are not working. Doesnt anyone else have this problem?

I get this issue sometimes on my Galaxy Nexus when 3rd party camera apps or apps that use the light are in use. The camera on my n10 works okay at least.
I guess I got extremely lucky. Ordered the minute it first become available (Tuesday, delivered Friday) and zero issues.
No reboots, freezes, laggieness, light bleed, back flex, dust, etc..... nothing, everything has been great.
Not usually this lucky....so I am extremely pleased

Light bleed through

So I just picked up the DNA today. Loving it! However, I just noticed that I'm seeing light bleed through on the bottom, just below the capacitive buttons when they're lit up. Anyone have this?? Really disliking this!
Yeah. Pretty common.
It is really easy to fix though and you can do it yourself. Unless you want to keep exchanging them and hoping you find one, this would be a better way.
Go to your local auto parts store and pick up this:
http://www.apmengineparts.com/82180.html?productid=82180&channelid=FROOG
Get the smallest one you can because you are only using a bit.
Take a toothpick and apply it to the bottom of the glass where it meets the plastic. Try to push it into the crack, if possible. Let it sit for a few seconds and then take a paper towel and wipe it off along the crack. DON'T get it into the usb port!
Let it dry for a few hours and you are good as gold. It also has the bonus of increasing water resistance and keeping dust out.
Mine didn't have that at all. I guess I got lucky. I do have a small spot almost dead center on the screen that looks like a bluish smudge though. You can only notice it on a white background. It's musky annoying but faint enough to live with.

I have two spots on the botton too...never had this issue with LED screens. How likely is it not to have the light bleeds? If this is indeed a common problem for the DNA, I won't bother exchanging mine

Hmm I guess it isn't something to be concerned about then.
I checked mine again right now in the office restroom with lights off and the phone screening an entirely black image; it does not have any light leakages at its full brightness, but there are two centered light spots triggered by the capacitive buttons that are only visible at the lowest brightness level.
Therefore presumably, turning off the capacitive button lights will eliminate the seemingly light leakages, as they do not seem to be defects caused by the LCD panel itself. But if such a leakage is glowed anywhere else but about the two centered areas just above the capacitive buttons, such as any corners or left/right/upper edges, then it would indeed be a sign of a defective unit.

Well in case nobody noticed when the lights are on and you are in a dark room and you tilt the top of the device away from you, when you get to a certain angle you can actually see the light from the buttons because of how the glass is curved. This will appear on every DNA because of the glass. so if you have light coming from BELOW the buttons make sure its not this that you are seeing.
I only have light bleeding through at a certain angle. I may pick up some of that stuff though.

In my case, its coming from the seam between the curved glass and the trim.
Mine too, I can see it from any angle. There's two spots where it bleeds, the gaps between the captive buttons

Well, at least I'm not the only one. Might just try to ignore it...we'll see how that goes...
Yeah I'm still torn about what to do. Kinda want to relock/ruu and exhange but what if the new one has something different wrong with it. This one works great, the bleeding is just visual and only in a very dark room so might just do what adryn did and seal it with some gasket maker

I just sealed mine. Took 5 minutes tops, and only because I was being precise.
No more light bleed and increased resistance to dust and water.

You think that's really what they're seeing? You can't physically stop that without changing the shape of the glass. i prefer the continuous curve over a slight refraction you can't ever see.

I'm certain (in my case) that its the glass and the trim.
Nothing a little black silicone doesn't fix. The shape of the glass is not the problem. The problem lies near the capcitive keys where the glass meets the glossy trim. They are two different pieces.

Does anyone here NOT have light leak?

I've been suffering the dust issue on 2 lumias now, and have noticed something. If you go to a darkish room/area and tilt the phone, you can see the light from the backlight coming through on the sides of the screen and also at the top and bottom by the capacitive buttons.
e.g. http://discussions.nokia.com/discus...ith_Windows_Phone/30650/1/2012-12-15-1679.jpg
I'm just wondering if there's anyone here who can go to a dark area, and see whether they all have this or not? Kinda worried me because made me think there's a manufacturing defect here and the screen isn't secured properly on the handset - which could maybe account for dust getting in? It might also explain the 'rattle' on vibrate that some are getting.
The three lumias I've seen all seem to have this to a certain extent (the light on the sides is usually much thinner and normally on either the right or the left - not both).
ANyone?

Funny enough, I had mine sent in for repairs due to scratches on the screen. After having the screen replaced I have NO light Issues and no more dust issues.
Seems during the initial build the screen is not fitted in or glued in properly ?

How would you define the light leak, eg, if I look at the screen on a very extreme angle, I can see through a minute gap at the bottom and see light from those buttons through it through the screen, but in normal circumstances it isnt noticeable at all. like the light isnt uneven or anything like that

Well it's like in the picture link that I put on the first page - Except as well as the top and bottom, there's also a small amount on the sides too that can be made to partly disappear if you push down hard on the screen there - I.e. the impression the glue holding the screen down is loose. It appears on all the ones I've seen, but I don't know, if you guys say you haven't seem it maybe I've just had extraordinary bad luck! It doesn't affect the screen when looking at it normally but it makes me worry for the future - loose things tend to become looser with time, and my theory is this, the dust and the vibrate rattle are interconnected.
I'm looking at my 920 and I think I see what you mean. On the top I see the light across almost the whole top but not at the sides or bottom. Is really a concern (I don't look at the phone at an extreme angle like that..)

Oh ok sorry, I didn't look at the pic. The vibration rattle (from what I've read) is just how it is because of the kind of vibrator (for lack of a better word I can think of) technology. Would have been good to have a nice clean vibration humm being a flagship phone...
Nothing seems to change for me when I compress the screen. Perhaps you really did just get a bit of a dodgy one?
Me either. I just did it again to make certain I wasn't lying to you. I cannot see anything from any angle. Now I'm starting to feel a little guilty.
I'm on my second 920 because the first one had a problem with switching back to handset mode after unplugging a headphone jack, but neither of them have any light leak! Maybe it is a manufacturing defect because of rushed batches due to the supply problems?

No light leak, but there are dust under front camera and once in a while the proximity sensor activates all the time.
