Strange artefact - Galaxy S III Q&A, Help & Troubleshooting

Hi!
This is my first post at xda, so first i'd like say welcome to all community .
Ok, lets back to the topic. So, few weeks ago I noticed a strange artefact (or something like that, I don't know how to really name it) on screen, it usually appears when I pull down status bar, especially on app with white background, its looks similar to this (screenshot in attachments) but its only white and black, it appears on bottom part of the screen, like a straight line, coming from left to right, I can't get a screenshot of this coz it appears only for a second, then dissapear. Firstly it appeared when I was using a dirt unicorns ROM, then I switched to SlimBean ROM with the Temasek kernel, but it also appeared on stock kernel. Should I ignore it, or it is damaged screen or GPU and is there any chance to fix it?
Oh, and sorry for bad English .

Thats a screen setup or testing picture probably an app or the display settings .

[Q] Banding on black background in stock lockscreen

The title says it. I made a completely black picture on my PC, and use it as the background for the stock lockscreen. Despite this, there's a brownish horzontal banding across the bottom of the screen that fades upwards across a third of the screen, when it should be black! I thought this was a screen deficiency at first, but then i saw that this banding isn't there when i display black images in the gallery or anywhere else except for the lock screen.
Build GINGERBREAD.XWKE1 stock ROM, rooted, Kernel XWKE2.
1. Does everyone else have this?
2. Does it go away with an alternative lockscreen?
3. Are there usually this many bugs on new Android-devices, as there evidently are on the SGS2?

I changed to a black blackground too a while ago.
As I found out it is actually better for your battary to have a black background.

[Q] Screen problems?

I bought the phone about 2 hours ago (I had the last version too). However, just before I did that I came here to read a little bit about the gps (to see if it was working or not) and then I saw many threads about screen problems and others... so I started to get a bit worried about getting the phone but I did it anyway
Well... during a quick test of the phone I saw that in my contacts and in the task manager screens appears to be a problem (I think)... the left top icon (contacts) has a small color degradation in its border from dark blue to light blue. The Task manager has the same thing but on its right side icon. Its pretty small but I am not sure if its decoration or just a problem of the phone in those 2 "screens" cause I dont see any more color problems elsewhere.
Does anyone else knows what else should I check (most common problems)? To check them out and see if got them too so like that I could go to the store and get a replacement.
Thanks a lot guys!!!!!!

Hi mate,
Don't worry..it's not a screen fault but a feature..
when you see the little colour degradation on "Contacts" and "task manager" means that you can slide left or right to see other features.
Just test it your self, open the contacts application and slide where you see the colour degradation.
Your screen is good, you don't need to go get a replacement.

Yellow line in lock screen

Hi All,
I have been using my galaxy s2 since last 1.5 months. No issues/errors/defects till today.
Today all of sudden a yellow line appeared in my lock screen. It is horizontal line coming between date and time. This line only appears in lock screen once I unclock my phone then line is not there which means it is not hardware problem. Please see the following pics with line and without line.
Guys, could you please help me how can I remove this line.
Thanks,
JM
have it too. disable the screen lock, then it must gone.

I think it's normal
Maybe you haven't noticed before?

No it wasn't there earlier...

are u sure? i think it was always there, but it could be that you had a darker background for the lockscreen
I'd like to inform those reading this post that I just experienced the same problem as the OP. No way to get rid of the thin line which wasn't there before. Corrupt lock screen wallpaper? I don't think so, since changing the wallpaper doesn't solve the problem. Also it can't be a hardware problem since the thin line appears on the lock screen only. I now notice this line on all types of screen locks (pattern, pin, password).
Hope this helps
It's just a line across the screen. It's part of the lock screen.

I dont have that on my lock screen, can you set the same image as a homescreen wallpaper and see if it also has the same issue? I've got a feeling its a defect or at least a SW issue.
Root your phone and buy widgetlocker....

It is not a defect. My phone does exactly the same. Maybe some FW has it and others don't, but it is not a problem. It is just part of the design of the lockscreen.
Obviously it isn't a hardware defect, since it clearly appears on the pics you posted, and those are not photographs.
It is also precisely in the middle position between the date and the alarm indication, therefore I'm pretty sure it's there on purpose, software coded.
Just a question: are you using the stock firmware / ROM / launcher??? I'm on stock firmware, ROM and launcher and yy lockscreen is far simpler... I just have the digital time and date overimpressed on the lockscreen picture, and nothing else.
I am having this problem as well, though my line is grey. The horizontal line goes from one side of the screen to the other between the date and the alarm time. This line was NOT there an hour ago so we can dismiss any answers like "maybe you just didn't notice it". The only change was that I powered down my phone and powered it on again. I, like most, originally thought I had a problem with my screen but it only appears on the lock screen. I normally use a pattern lock but I checked and the line appears when it is on number lock as well. My wife has never used the lock feature but I set one up just to see and she has this line as well. It doesn't serve a purpose and it wasn't there before, I'd just like to know why it is now. Can anyone shed some light on this? Thanks in advance.
If You setup PIN lockscreen and then go again to lockscreen settings phone asks You for your PIN before allowing to change settings. This line is there also. It's not a "problem" or a "defect" it's just a part of the lockscreen design. You act like it's some kind of a disaster and huge bug which renders phone unusable but it's just a line separating date from time seen for about 1s when unlocking screen. Do You think there should be a switch do disable every part of android interface ?
Ps. to be sure - I rebooted my phone and this line is there also just after reboot. And this line is not grey - it's semi transparent. I'm certain that in my case it was there from the beginning.
Ps2. look at this or this one - returned by google images for "sgs2 symbol lockscreen" - nasty lines everywhere
If You hate this line soo bad try to prepare wallpaper that has it's own line at this position which when merged with this semi transparent line will become invisible.
This has appeared in mine today. I've also noticed sometimes that the lock screen touch screen messes up occasionally and when you drag between the lock dots to do the pattern; it drops the line drawing after a dot when you change direction.
If I turn off the screen and light it up again then once or twice it fixes the drawing problem, though the horizontal line is still there.
Has anyone on this thread experienced degradation of anything on their phone since they noticed this lock screen line? Want to catch a fault before my warranty runs out (if there is a fault!)

[Q] Screen flickering

First of all, I'm new to Android phones and this forum I'm not sure if this is the right place to post, if not, let me know.
I've purchased a Cubot One, knowing what I can expect and it really works fluently, but it comes with an issue, annoying sometimes.
Left half of the screen flickers (in a very exact way, just left half), depending on what it's showing. For example, desktop 1 shows the wallpaper and icons flickering, but if you go to desktop 2 that effect disappears. It never happens in an open app, except if it's showing a bitmap or icon, and not always. If you're in the block screen it never happens. If you're using, let's say, Whatsapp app the screen is perfect, and in most of apps.
I make a complain to the seller and waiting for their diasnogtic, but I thing it could be a software issue, so I'm writing here. Could anybody make any suggestion?
Thanks

Please help - Samsung Galaxy S5 - Dark screen

Hi everyone!
I just received an used Galaxy S5 from someone and it was working properly, it was a gift for sure.
I had some fun exploring it as I never had any phone like that one, I downloaded something was spending time on that app and the phone was turned off because the battery was low.
When I charged it everything was ok but the opening screen like Samsung Galaxy S5 , powered by android and it never went to the main phone screen it was loading and like it couldn't load till the end.
So I was able to enter the recovery menu before booting and I believe I made some mess there including chosing the wipe system option and so on, anyway the phone finally restarted , went to normal screen but after some attemps it resulted in having Galaxy image on my screen when rebooting with some sort of extra image flowing in the background / some colour stuff etc. I just took it as it's reinstalling the soft from new , like a fabric version you know so I left the phone on table and it took like an hour and it wasn't finished , maybe I could have waited some long but I decided to reset the phone at this point and the screen went dark and never returned. I can observe some blue light in the top left corner of the phone, my friend took this phone from me yesterday and even tried to use some Odin software to install software however he made it all in let's call it Blind mode. Phone seems now to have some sort of voice in foreign language, I dont know what is it , but like a navigation in car.
Screen remained dark from that time and never came back.
Do you guys see any chances saving my phone ?
Appreciate any help and tips, ps: be aware I am not a phone pro and I know to much about reinstalling soft etc. but I have intentions to do it with instructions if necessary and if it could help
Thanks!
Hi let try to explain me better :
1.extra image flowing in the background / some colour stuff etc.
Do you mean when Samsung Logo appear like this :
https://www.youtube.com/watch?v=c8nF9tbVEHQ
you have burning effect which means your LCD is damaged it looks for example something like this :
https://www.youtube.com/watch?v=tkYXobLkjDA
When you say you hear Voice like in Car Navigation that means that Voice Assistent (Talkback) is On try to disable by fast pressing 3 times home button if not re-flash latest version of firmware just tell me what is 7 and 8 number from imei which you can find under the battery on sticker.
To send you correct firmware for your Phone Country Code .
Bad things if nothing of that can help you probably your screen is dead , or flat cable doesn't have good contact on mainboard .
Hi Teddy
Thanks for your time spent on trying to help me here ! It's really appreciated!
I would like to say that -> 1 . yes exactly I seen that image when everything worked properly and it seemed that my phone will have system reinstalled , this animation was loading for about 1 hour or so, and at this point I have cancelled it and my screen went dark forever!
2. No it's just dark totally dark nothing can be seen, everything was just perfect before ( phone is from Germany used about 3 years I guess as the battery has such date on it 2015.03... ) I live in Poland so it would be the best if the software was in polish language.
3. Yes I hear the TalkBack for sure and it's no problem to enable/disable it , anyways screen won't come back to become working properly
I believe I might have screwed this phone a little or maybe I am wrong and I didn't do anything bad at all why I am saying this : short story how it was
1. I received it few days back and I was there with my sister I took it from her and was enjoying it like a kid enjoys a new toy
2. I was having fun on it, it happened it was dead because battery went down to 0% but I charged and everything was perfect, after that I started downloading extra stuff -> android apps and I noticed after another charging it stuck on Samsung booting screen ( White letters on black background ) it didn't want to move forward to the system ( normal functioning ) - at this point I knew it won't probably load anymore and I won't be able to use it so we went to console let's call it ->
3. When we were in the console there were few options, to reboot, to remove something / swipe ( I am not perfect in english all right so I did it intuitionally ) , I believe I for sure chose to remove /swap system and then as you mentioned in YouTubue 4 sec video I could see the samsung loading screen with that beautiful logo and animation, so I thought the system is reinstalling and it will take a while, and here I waited about 40 mins - 1 hour and I gave up and restarted the phone here, after that the screen went totally dark and dead but... ->
5. But after rebooting I was still able to see just 1 option, not any other , this one option was to connect device via odin and install system , with android alien green funny picture on it , waiting for connection
6. Short after something happened and I couldn't see even that, screen was dark and remained dark for good
7. Yesterday phone was taken by my friend to his home and he claims he reinstalled system, it was possible to move intuitionally by fingers and voice navigation but screen never came back
8. Now it's impossible to see anything on the screen in fact, I can't even determine if I am accessing pre-boot menu where I could reinstall anything or not, really I can't know it so it's just dark , standard buttons on the bottom of the Galaxy S5 are bit highlighted by white light like an icon on the left and right of the bottom wide button
9. The diode on the top left of the phone happens to light regulary in blue / dark colour
10. That's really all - I don't know here whether I should go to some dude working on phones and if he tells me $50 to fix it in Poland it will be bit over 1/3 value of new phone so is this worth an effort I don't really know, nothing helps really I tried everything my colleague used to fix some iphones himself so he isn't totally newbie to this subject
