Possible screen defect - Galaxy S6 Active

I have been having bad luck with my new phones. I decided to get the AT&T galaxy s6 active. My first galaxy s6 active developed a lower microphone problem. The microphone was garbled at first, which I attributed to bad signal quality when I made a call and it sounded bad.
Then it stopped working altogether, which I discovered when Google Now stopped working. AT&T completely replace the phone, after an hour wait in which someone had to run across the street to retrieve a replacement.
After using the new phone for a few weeks , I noticed that while displaying gray colors, faint lines would be visible on the screen. This is slightly visible on scrolling images of solid colors. Actually noticed while playing game called arrow, and I thought it was dirt under my screen protector. I remove the screen protector and clean the phone, but the lines remained.
I checked another galaxy s6 active that another family member owns that has the same screen protector, and he had similar looking lines only apparent on gray colors, although they were even fainter and in different positions and numbers presumably. I check a third active that's never had a screen protector. It had the same lines. These are all new phones about two to three weeks old. I checked a normal galaxy s6 that my sister owns, and it did not exhibit those lines.
As far as I know both phones have the same screen but the galaxy s6 ACTIVE has a waterproof coating. This is a side effect of having the coating ? I did contact live support which was no help at all. He / she I just advised me to return it to AT&T, which I am NOT doing again especially if it's might B a normal trait. Any ideas?

XPERIA Screen/Backlight Problems

Hey guys and girls,
I got my brand new X1i on an O2 contract today, ordered through the internet.
However, when switching it on, the first thing that stands out is the screen isn't all black. The upper right hand corner fades to like a dull greeny tinge as if its under pressure or something.
After fiddling around with it, it seems to be the backlight as in bright light, the colours all look fine and black is black. This is also the cause if the backlight is put at it's dullest, but it's most noticable when its at it's brightest.
Is this a issue with all Xperias or just mine?
And is this serious and worth contacting O2 about or will it be okay?
BUMP.
Could anyone tell me simply if this is a common problem, if not, I'll ring O2 now.
A quick reply would be nice
I haven't seen it before and I haven't seen it reported before. If you think it looks out of the ordinary, too much to leave it be, you should indeed phone O2.
Cheers, I shall call now
Post a picture so we can compare and lets us know how it turned out, mkay? =]
Heres the best photos I can snap.
The first two don't really show it well, but the third is the best.
Trust me, when you first switch it on and the Sony Ericsson logo appears, the whole screen is black and that corner fades to that dull green colour. It stands out quite a bit, it's also noticable on the Panels screen.
If you have a dark photo showing, it can affect the colours on that too.
For such a pricey phone, I expect it to be flush black across the screen.

I just got off the phone to O2, they get the phone from a third-party so I am expecting an email from them. The woman on the other end said, most likely they will swap it for a new handset at the door, or take it for repairs....but it will say in the email.
Ah, classic case of backlight bleeding. Send it back and you'll get a new one.
Well, hopefully, before next week is out I shall. Just waiting for that elusive email, they said I should have received it by Monday.
Thank you for you're help, I appreciate it
There was a thread on this, some have it too.
I have it as well, black light bleeding. I dont really mind it much since I rarely notice it.
Ive decided to leave it alone since my X1 is unlocked and it'd be a massive hassle to send it away to SE.
I'm pretty sure its common. Even high end LCD TVs have the problem sometimes.
I had it on my first x1 (which I dropped and got a new through insurance), and I've also got it on my new x1.
However, I barely notice it, so I'm okay with it
I wouldn't mind so much if it was white but its a green colour, thats more annoying.
It's gonna get sorted anyway, most likely, they'll swap it at the door for a new one.
I was looking for information about the SPB mobile shell and found this thread.
I also have this issue with the top right corner of the screen, especially when I switch the phone on (on the black startup screen with "experia" written in white).
After startup, I don't really notice the issue since this area of the screen is almost never black (except when switching panels and sometimes when watching videos, but it's hardly noticeable). I'm now wondering if I should return it or not, I got the phone on tuesday and already had to do a hard reset (and reinstall everything I had just installed before) because I couldn't send or receive text messages! I really hope this won't get any worse...
(My phone is a french version, and my carrier is SFR)
Ive had the same issue w/ one...i just returned to BestBuy yesterday and now the replacement is also doing this as well...1 day later
Me too, bugging me like crazy, but seems to be quite common.

Mine has it too but its really not a big deal. I've only noticed it on bootup.
Yeah, don't mind it on startup - who watches it start up?
But I notice it when using the camera (in the black border) and
when switching panels, that's where it's annoying.
- Anthony
yeaa, i got the same problem too. Went over to the sony ericsson centre and they don't have a clue what it was. They said they'll look into it, and thats it. No replacement.
Not happy
i live in indonesia by the way..
Mine too has the issue. Both upper corners are bleeding greenish. It's obvious when the screen is black, not only on start-up, all the time. For example, look at it when playing a movie trailer with really black scenes, it's there.
It has to do with the pixels, not the back-lighting, from what I understand of TFT functionality.
Remember the dead pixels issue on TFT screens? Well, the dead pixel means the transistor of at least one color out of the 3 (RGB) is dead, either locked closed or locked open (anyway, not being able to modulate the light intensity of the subpixel color), so the color is either missing or present at a fixed value, the overall color of the pixel not being the required one. In this case is an issue of mismatch of transistor parameters.
The GREEN pixels do not close completely to block the light. Being a progressive issue from one area to another, it's clear that the thin film transistors are progressively mismatched by the process errors. This is process error in the TFT technology (I work in microelectronics). The process masks can get errors (not the case here), or the masks are ok but the etching process is not properly adjusted. In my Xperia the bleeding gets progressive towards the corner, having a starting point like a center from where it spreads. That is because the etching involves chemicals and liquid flow to spread and cleanse those chemicals. My opinion is that the flow in the case of this particular TFT screen model is from the bottom to the upper side, where the upper corners are the bleeding areas for the chemicals and the effectiveness of cleansing is lower, combined with surface tension of the liquids. The transistors get progressively mismatched in parameters (beta factor) and since they all get driven with the same signal, they block the light less than the good ones. Nothing to do about it. Theoretically it might be possible to map out those pixels and provide a corrected voltage for the mismatched transistors (correction table in the GPU DAC ROM), but this is like tooth extraction through the ass hole (or replacing the spark plugs through the exhaust pipe). It's simpler to just get the ****ing screen right. Sorry guys, we are out of luck here. It seems the 800x480 3inch TFT's are not yet top quality, or at least the ones used by SE. I'm really frustrated that the manufacturer used a cheaper screen in a 600-800$ product. This is how a company can loose customers and get the image crumpled.

[Q] Broken LCD display

Hello,
I got a problem which I believe can someone with more experience help me with. My topaz got dropped on floor from arround 1 meter height and possibly on the display side. I didn't pay attention but when I looked on it after some time, I noticed black dots over almost half of screen. I posted image to this. It has irregular shape so I believe it's some liquid thing and not necessarily hardware fault. As my warranty ended 4 days ago, I don't think about sending it for repair. I thought about disassembling it and clearing the display from this stuff, but first I'd like to hear your opinion on this. If everything goes bad I believe new displays can be bought (although they're quite costy, so I'd prefer fixing it.) The display is fully functional other than that stuff on it, also digitalizer isn't broken and I receive right input all over that place. Colors inside that shape has a very light blue color tone when displaying white.
Dunno why, image doesn't display so here are plain links:

AT&T SGNote-Screen Mode missing?

I finally checked out the SGNote today in an AT&T store for an hour (both it & a case fits in my pockets & feels fine in my hand/s but the huge screen is startling at first then I started getting used to it) but they did not yet make the S-Pen available to play with (fearing people would steal it I guess).
One thing I did not see was Settings->Display-Screen Mode->"Dynamic, Standard, Movie"?
A Google now turned up:
http://phandroid.com/2012/02/18/samsung-galaxy-note-review/
"One of things sadly missing from the Note (and is present in the Epic 4G Touch) was the Screen Mode option in the display settings. Not exactly sure why all Samsung SAMOLED devices don’t have this option but it was disappointing to see this left out of the Note. Being able to turn down/max out the amount of color saturation on your SAMOLED device is one of the best ideas since.. well, SAMOLED."
WTF? Why? -Thanx
Sorry just noticed http://forum.xda-developers.com/forumdisplay.php?f=1494 but I'm still curious from people here as well why AT&T removed this?
http://forum.xda-developers.com/showthread.php?p=22729889
I assume if I get the AT&T version, root it I could add it back?
How easily? Please confirm -Thanx

[Q] Galaxy S6 Active Users

Me and my best friend bought the Active 3 weeks ago and I'm noticing while I'm viewing with a white background a visible black box inside the screen when I'm outside in the sunlight.
I just looked at his today and I see the same thing. Does anyone else see this?
I've read reports of this before. I think it's just the structure of the screen. Since you can't see it unless you actively look for it, I wouldn't worry about it. AoN

Samsung Galaxy Note 5 S-Pen Sensitivity Issue

Starting a new thread since I could not find any existing thread on this and it is quite surprising since this is a widespread issue and for the same reason Samsung service here in Melbourne even refused to acknowledge this is an issue! There logic seemingly being if the issue is present in the demo unit in the store as well, it is not an issue! Vodafone has also refused to honor the warranty, even though it is in the first month of my contract and they should be replacing the handset and dealing with Samsung, and have instead told me to provide them with an acknowledgement from Samsung stating it is an issue! Talk about deadlocks!
Now coming to the issue, I have found out that there are sensitivity issues when using the S-Pen on the bottom right and left corners of the screen. There are issue on the top part of the screen as well but they arent as serious. I would also request you to check the same on your device and report back if you are also facing the same.
To check, first get into diagnostics mode by dialing *#0*# and then go to the S-Pen tab.
1. As you can see in the video, the bottom right and left corners have definite and serious issues with S-Pen sensitivity. I found this out, and it is also a use case and one of the major reasons that I went for Galaxy Note 5, while taking a screen grab from the middle of the screen right until the bottom right corner. I just could not do it. As soon as the S Pen reaches near the corner, the sensitivity issue makes sure that input isn't recognized. Not only this, even when it manages to identify the touch, the tracking is random with the S-Pen having a mind of its own.
2. The second issue is while drawing on the top part of the screen with the S-Pen but this one is not as serious as the first one. You can see in the video that S-Pen loses sensitivity in one particular area of the screen. This is easily corrected though, by pressing the S-Pen harder on the screen.
This is apart from the lag and slowness issues that rear their ugly head every once in a while and in a phone which runs an Octa Core CPU with a whopping 4GB of RAM. This is my first Samsung in a long long time and it has left me disappointed again exactly like it did in the past whenever I bought a Samsung phone. To me the level of polish of the hardware on a device costing as much as this is simply not acceptable. What are your thought? Please report in this thread if you are facing the same issue as I am with the S-Pen.

I have multiple stand-alone S Pens and don't experience what you're describing with them or the one included with the device.

Strange because I could replicate it on all the demo devices in the store. That is their reasoning for refusing the warranty as well.
I'll say this, the included pen is more responsive on the display than pens that are pre-Note 5 so something in the pen and/or display has changed.
Does it mean mine has a problem then? I am wondering if anyone else can also confirm the same?
I can confirm the bottom left and right corner of my note 5 behave just like OP's does... but wouldn't have found out if he didn't mention it

Thanks Alex. I found the issue because I could not take a screenshot which finished near the bottom corner of the screen. Now smart select is a headline feature of the phone and this hadrware oversight to be is just not acceptable. The Samsung service would not acknowledge it as an issue let alone do something about it. May be it is only on the first batch of phone. Who knows?
I checked my phone (SM-N9208 TW, mfg: will add later) and the bottom corners have poor tracking with the hover point flying off the screen when held above.
Overall this issue shouldn't affect the usability of the phone if you rarely use these areas since it's still possible though difficult to use the s-pen there.
Edit: I re-tested with my phone flat and s-pen vertical*. The s-pen can be used on the very bottom corners with precise movements, so I don't think will affect usability for most people most of the time.
*Having the s-pen on an angle can affect the tracking significantly as seen in your video. I think the only solution would be to modify the s-pen to track at the very tip. This would probably make the tip non-replaceable and/or more complex and expensive. If someone has time, try using the s-pen without a tip and see if/how it tracks.
Update: I tested a SM-N920W8 in store and it had the same corner issue.
I complained to Vodafone again and they decided to take the phone back. Back to trusty properly working iPhone 6s Plus 64GB. My last Samsung device no matter what the specs. I wouldn't be interested in one even if it will have a gazillion core CPU and few petabytes of RAM.
I have the same issue. Can anyone else, note 5 users confirm about this issue. (Bottom right hover issue)
I dont't face that problem
Edit: here is a screenshot
https://drive.google.com/file/d/0B5LZ1p_SFZ3faTFJNzBzZGlnbzA/view?usp=docslist_api
Mine does it a little bit.
It still passes the test so I believe it's within spec. I honestly don't see it being a warranty issue.

Sometimes, it is the Cover magnet.
Sometimes, it is the Cover magnet. . Try to remove you phone from it and try the s pen in the touch area in question. It worked for me with in a leather flip cover. The same for the s note stopping error message.
same here

if you have magnetic casing will get such problems ....
or fake s-pen need to replace with original or better fake quality
My stylus is overly sensitive; so much that I can't write properly. All text is in continuation even when I lift the stylus off for whitespace. I even followed the article on adjusting the sensitivity of the S Pen by removing the click-button cover and adjusting the Potentiometer. However, the note 4 s pen is entierly different as it doesn't have any Potentiometer under the click button. Link to article:
http://forum.xda-developers.com/showthread.php?t=2191333
What annoys me most is that I never had this issue before I flew overseas last month. I started experiencing this issue after I came back and it has rendered my s pen useless. Has anyone found a way to adjust Potentiometer on the new S spen yet (it might be located under top cap but i'm not sure how to open it).

I am having this same problem. Did you ever find a fix for it? Thank you!
Yes confirmation of problem
I found the same problem. If you try to draw a square in the S pen test mode you cannot draw a square in the bottom left or right corner. The square will turn into some kind of strange wiggle shape.
I live in Malaysia and went to the official Samsung head office service center and they confirmed this is a problem with all Note 5 models and the lady showed me her own personal Note 5 which had the same problem (actually worse than mine).
The service technicians said they do not know the reason for this problem. But as an electrical engineer I suspect there is some sensors in those areas which cause interference with the S Pen.
