Keyboard afterimage/artifact left on my screen - Galaxy S III Q&A, Help & Troubleshooting

I got my s3's cracked screen get fixed by this guy on ebay. (GLASS ONLY LCD WAS FINE)
But after I got my phone back, there was an afterimage of the keyboard left on the bottom of my screen. I don't see them that well in dark images but on white screens I can see it.
I heard afterimages can be left on AMOLED displays if the image is left on (without refreshing) too long. I think when he was testing my screen, he left the keyboard on for too long. And I also heard this was a permanent mark.
So I emailed him and he replied that this indeed does happen while replacing the glass and his customers have reported this too and this does go away after a while. But, I thought these image artifacts were permanent. O_O Is he just telling me this so he wouldn't have to replace my LCD(which would cost 100~ dollars.)
1) Does this go away? 2) If so, how long does it take ?
2)Does this actually happen when replacing the glass?
Thank you so much!

Possible pixel problem on second Hero phone, help ;(

Yesterday i bought a HTC Hero (my first one). When i turned it on and toke a good look at the starting screen (the one that says Hero, and HTC), i found a white pixel, probably dead or something. I went back to the store to get a new phone. This was not a problem at all and i got a new Hero. Now again, when i turned on the phone and toke a good look at the black screen, i also found 2 pixels with a other wierd problem:
The pixels also turned out white when i looked at them in a specifica angle. Just to be clear, i am watching on a black screen (starting screen). If you look at the screen and not in a specific angle i cant spot the pixels directly, but when i tilt over the phone slightly they show up and are 2 little white dots.
After i found out i downloaded the Detect Dead Pixel app. This app can create a black screen, the same screen as the home screen. When i use this app to spot the pixels again they are way less visible than on the home screen... I can spot 1 of them a little bit if i look at the screen in a certain angle and i can see a little dot, but i cant see them that good as on the home screen. They are not visible on other colors, only black.
I really dont know what to do with the phone now ... does anyone know what this is? im a bit concerned. Thanks!
After a bit more research on my phone i firugred that the dots really arent that visible. Maybe its just dust under the screen? When i put on a black screen using some kind of Android app i can not spot them. If the pixel is lazy or dead it should be clearly visible on a black screen right? for the lazy one then.
Anyway, i spotted a other problem on a black screen:
A brighter spot on the top part of the screen (like someone is pressing on it a little bit). Is this a problem ? im deciding if i should return the phone again..
Well its entirely upto you mate - i dont know what contract you've taken out but you may have that phone for 2 years. If your not entirely happy with it i'd take it back while you still can.
Issues with the screens rarely correct themselves.
My first Hero had around 10 dead pixels and i got it replaced as i wasn't happy with it. I now have one with a perfect screen and i'm really happy with it!
Well i just returned to the store and got another phone. This is the 3th one, and it still has problems, even more then the previous ones ....
On the boot screen there are about 10 very very tiny white wierd points visible ... im getting a bit frustrated here. What is this with all the screen problems ? :S
looks like they got a bad batch in your shop... have you considered powering up the phone while you are still in the store? might save you same time and way...

I have done that, but as i said, its only really visible in a dark room with screen brightness on 100%. I have checked the phone in the store and it just wasnt visible. When i checked the screen in a complete dark room i spotted the little things again. Looks more like dust to me =\
If your brightness is 100% you should see that one single pixel immediately.
Try making an image in paint (480*320) with a black background and a single white pixel. Open that image on your phone. The dead/lazy pixel should be just as bright as the one you drew.
Also the brighter spot is normal. It's called "backlight bleeding". Every lcd screen has this 'problem'.
They are not clearly visible, i think they are smaller then pixels, but they are countable on the bootup screen. When i tilt the screen them seem to change color (might just be dust). Green etc. I dont know what to think of it, come on. A wrong batch shouldn't be the problem if its dust, then its just a assamblation error. But 3 in a row?
I'm getting a bit pissed
It's dust or a fingerprint blocking a very small subpixel. Can't you just wipe it off? But I suspect very tiny scratches.
idk whether this is possible, but it might be dead subpixels. that would explain why they are smaller than a full pixel...
Does anyone know if that is possible? it sounds like a good explaination. Dead sub pixels could be the problem. They are smaller then pixels, but beg enough to be counted (i can count over 13). Little white dots on a 100% brightness black screen.
It must be dust, its a common question among hero owners. Most of the time the things they see is dust. It would be crazy if all new hero's have up to 10 or 13 dead pixels.
Ok well, here's what happened next:
I returned my phone again, god my cash back, bought a new one at a other store, SAME problem. Swapped it for a new one again, same problem!
Got my money back and i completely changed my mind of buying a Hero.
It is not dust. Its a perfect white dot, and definately some kind of pixel issue.
To bad..
Are you sure you're not being pixel-paranoid?
When reading all of this it sounds mostly like small dust particles under the screen. And looking at the number of phones you have tried, chances are you also got one with a real dead pixel (hot pixel, always on).
But I also think you are obsessed about it. My phone also have one dust thingy somewhere which I found just like you did (pixel tester, black screen). Smaller than pixel and less bright though.
I never notice the thing under normal use, unless I really go searching for it with a black background.
So you might make it bigger than it really is and miss out on a really nice phone.
Then again, we all have our own quality standards and its good yours is a high one!
I have had a tiny dead pizel since I bought my phone. Only really see it on the bootscreen.
I was always more bother by the light you can see coming from under the keys at the bottom and near where the lcd meets the keys.
I also have 3 dead pixels but they aren't that irritating.
I also discovered them when booting up the phone, but for me, they are sea blue (all three)
Maybe it is 2nd hand stuff HTC uses on their phones?
i have about 7 or 8 dead pixels too. it doesn't bother me too much anymore... only notice it in a completly dark room on the boot up screen... probably a common problem with the lcd screen the hero uses
All Hero's have this, or will have it inevitably:
The screen does not connect fully; there is a rubber-border between the glass and the metal frame surrounding the screen.
Look from the right angle, and you can see that there is a small 1/10th mm opening. Dust will come through here, and it will get on the screen.
HTC will wipe it off free of charge of course.
It is NOT a dead pixel; these can be seen from any angle, although the color changes a little but because of the viewing angle.
Call HTC and say you have dust under your screen, they will fix it for you, free of charge.

[Q] Galaxy s2 screen repair fail - buttons dont work now

Good Day folks, here is the long and short of it.
Galaxy s 2 fell and the screen broke
I bought a new screen
Replaced the screen BUT two big problems occured.
1. The screen appears to have less colours than my original screen
2. NONE OF THE SOFT KEYS WORK, HOME, MENU AND BACK DO NOT WORK.
Number 2. is the big problem. Does anyone have any idea how these buttons work?
Even when I press the buttons directly with my fingers with the buttons off they still do not work.
Im baffled. Please help.
I also have attached pictures of the button area
It happened to me, I removed the screen, I replaced from beginning and it worked...
Hi Collado, do the white things behind the buttons have any electronic functionality or are those just things to make it stick?
To all future readers. I found out what the problem was. Basically,
The home, back and menu keys are all connected to a single ribbon. It appears there is a tiny piece, connected via the back key. That was torn while i was ripping off the the screen and digitizer.
See the picture attached
How much did you pay for your replacement screen and where did you get it. My digitizer is broken due to a drop. My front glass is perfect but the digitizer is completey shot. How difficult was this project?
Hi Johnboy
I cant remember the price of the digitizer offhand but make a check on ebay.. that is where i got it.
Difficulty is high as you need the minature tool set to do this effectively and a gentle touch.
However, it still appears as though the screen I bought has less colours.
Sorry to jump in and unintended hijack
I also dropped my S2 and cracked the screen, and after checking around dropped it in to the Geek Squad at CPW. Who duly replaced the screen and digitizer for £80. Only problem is the screen seems less bright and if moved off the central viewing angle the screen dims, as if it wasa standard lcd and not the orginal AMOLED screen. Does anyone know if they make lesser screens or was it fitted badly.
Any advice greatly appreciated.
DM.
I would go back with it and complain.If you dont get satisfaction then do an impression of the guy that goes into the pizza shop in "rise of the foot-soldier" film.

[Q] Issues after changing the digitizer

I have just changed it, but after assembling it, I noticed that even when the screen is off there is a zone that looks like when a car left an oil spill on the road and with certain angles of light you can see green~blue~purple colors. Pic of what I'm talking about: http://i.imgur.com/n5CXv.jpg
I would like to take one of the screen, but for now I'm unable. I'll try later asking for someone's mobile to take a pic.
After taking off the digitizer again, I noticed that it didn't had that colors. But after putting it back on the phone, it had. Seems that it only has it when it's properly placed.
Does anyone know how to stop this happening? It's annoying.
EDIT. When I touch near that zone, it looks like if when you touch a flat screen.
digitizer is making pressure on lcd.

That was the problem. I compared the new digitizer with the old one, and seems that the old had a felt pad along the borders of the screen. I took it off and after putting it in the new one, the stain went away.
Thanks a lot.

Screen Ripple effect normal? Or Defective?

Okay,
This happens only on the bottom right of the screen, if I press down with a little bit of pressure you can see the LCD screen distort, This occurred on my 1st device (requested a replacement) the replacement does the same exact thing in the same exact area.
So is this just a overall defect with the device (Since it's present on more than 1 device I received) or something with just a bad batch?
To test:
Open up the browser, on a white screen landscape mode, just use some pressure with ur finger press on the screen and the lcd will distort/wave into blue-ish color. Do the same test around you will see that 1 side will always have this effect but the other 3 won't.
The old device this issue was far worse than the new one. Only other note to make.
No issue here

That's bad.. but it wont cause any issues if you don't press on the screen really hard
Well I'm exchanging the second device as well.
Will keep going round and round until one without a defect lands in my hand.
On my Galaxy note 2 no matter how hard I press nothing. DNA little pressure it begins, the 1st unit was very easy to cause the ripple effect, but the second unit was much harder maybe 3rd times the charm.
Well 3rd device does it as well so its an inherent trait of the product.
It sounds to me like the screen is set in tilted a little. A lot of HTC phones have this, I've noticed. Almost all the replacements I had on my rezound you can clearly see the screen set wrong from the light leakage on the bottom of the panel. Actually, I just pressed the bottom right* corner of my screen (the part that's higher) and it actually does the same thing but it's barely noticeable though on my rezound and only on darker colors.
Well the DNA is going back this is basically un acceptable to me. 3 units all of them do it, if you lightly press on the screen it will ripple.
The funny thing is I can feel the difference when you press down on the left side of the device it's much stronger than on the bottom right.
This is definitely not an issue on my phone. My One X had this issue. (coupled with the light bleed from bottom ). Looks like some DNAs are affected by same issue.
But its definitely not common thing. The second DNA I had ordered for a friend was received yesterday and both are perfect with no sign of any such screen ripple issue. Might be the case of bad batch at particular store.
No issue here on my phone. No offense, but it sounds like you are looking for a reason to switch phones. You either have extremely bad luck to get three defective phones, or you are trying too hard to find something wrong.
It happens to me when you press directly in the middle of the phone. Although it's not an issue for me, since the amount needed to press to see it would not be used on the phone on a regular day.
I'm going to try a diffrent source. Yes all the devices have this issue.
I'm going to post a video as well.
Mine does this as well, turns like a purplish color like if you pressed hard on an lcd tv. It hasnt bothered me at all and i love the phone but just wanted to say i have it too
All of the devices have this effect.
My HTC One X has this thingy but you have to press hard...which is not what's intended with a capacitive screen, the problem is that the more the phones are slim and the more screens are fragile, just touch the screen not press it
Not all devices have it but the dna def does have it.

Cloudy area displayed on white or light screen

I bought my N9 32GB white from Amazon Warehouse on Feb. 17. It was the second I'd ordered. The first had a defect (bent frame). All has seemed well with this--very minimal light bleed; no dead pixels; recessed but clicky buttons; no squishy back--in fact, very solid. For the past two weeks, I've noticed a cloudy area about 1"x1" just below the horizontal midline near the center in portrait mode. It looks like a smudge but remains after I wipe. It's particularly noticeable as I scroll white-background screens. I even changed my Tapatalk app to dark mode to avoid it. I've tried to get a pic of it, but it doesn't show up well enough, if at all.
I came across a similar situation of someone seeing dark areas on light background on his LCD panel laptop after he had sat on it. It was reported that applying extreme pressure to an LCD screen could result in this phenomenon. I have not applied any pressure to the screen, but as it is an open-boxed item, it could have happened.
I need opinions from those who know about these things as I know nothing. ATM, I'm trying to train myself to scroll a page from the center so that my fingers hide the "shadow" which is also what it looks like.
Thanks

Hi, ritchea...
Sounds like you've not had the best of luck with the N9, this being your second one.
From your description it certainly sounds like a hardware defect with the screen. A manufacturing flaw perhaps, or something happened to the device whilst in transit or in storage at the warehouse
If it really bugs you, you should get it replaced.
I'm a little OCD about this kind of thing, and no matter how much you try to convince yourself it's nothing and to avoid looking (at the screen flaw)... subsequently, you spend all your time **thinking** about not looking... And eventually you look.. And wished you hadn't... if that makes sense. It detracts from your enjoyment of the device.
Rgrds,
Ged.
I'm a bit (more than a bit, really) OCD. I've owned over a dozen devices but never experienced this so I also assume a defect. I just needed to know if this is a possible defect that is known-especially when trying to get service.
EDIT: As this thread had had over 200 views, I'm throwing more info out there to see if anyone has any further insight.
I factory reset the tab --all stock except for relocking it. Darn if the spot didn;t seem to disappear. Then it returned. At that point, I decided to revisit the back. Hmmm. There is a little give in it--not spongy, but when I applied some pressure, I heard a sound in the middle of the tab like adhesive reattaching. (I've looked at the teardown and know that a lot of tape exists but not from the back cover to the rest of the tab.) I looked at the white screen, and again, the cloud was gone. In a few minutes, it reappeared. So, I firmly rubbed the mid-back and the cloud disappeared. I've now tried it over a dozen times (after restoring my nandroid), and applying firm pressure to the back always, but temporarily, removes the cloudy area. Can someone say what's most likely causing this? (I know it's faulty hardware, but I mean, what is happening to the screen when I apply pressure? Maybe a bubble in a layer somewhere?
Because of the camera, I don't want to get into taking the back off. I chatted with HTC to make sure my Amazon warehouse tablet was covered, and was told that it is even though (from the CSR) Amazon is not an official HTC retailer.
