both the still and viewfinder display show these lines
(a reset to factory settings via the camera app restores it to normal)
is this something anyone else has experienced?

it's just 1 of many screen names of someone who is upset about something the Mods have done.
does the camera only have the issue with stock app or does it do it with 3rd party apps like Camera 360?

Yea i'd have to agree download a second Camera Application to see if it happens on a secondary program. That will isolate the difference between a bad camera or bad programing.

you know i didnt look and see if camera360 was doing it
my suspicions lie in the camera app getting wonky (see: using multiple programs and getting a bad driver warning...please restart)
it happens
ill check another app besides stock when it happens again
thanks guys

This is a common issue when taking digital pictures under florescent lights. Its due to the frequency the lights flash at.
It is a very inconsistent problem in most cases. A better way to see if there is really a problem is by taking pics in different settings and lighting conditions.

nailed it
the 2x it has happened has been in similar lighting situations

This happens to me with my Epic when I set it to lock at 800 ISO

At that point your bringing a lot of noise(grain) in so the issue is amplified.
Many think mega pixels make a good camera. This can be no further from the truth. The sensor and processing is what really makes the difference provided there are good optics(lens). Something you will not see on a phone. Nokia is still the only one that has done well here.
You are going to get noise and banding with cell phone pics unless the lighting is optimal. Its a give and take that has to be dealt with. Phones have terrible lenses and cheap sensors. The two key functions to a quality photo. The only reason they look as good as they do is processing done in the built in software.
The cameras on the phones these days are doing well but will never replace your point and shoot or DSLR.

DSLR Photo Illustration of visible screen burn + ink marks issue

Hey xda members,
just had a bit of spare time so I decided to make some photos of my GS2 while displaying a totally black screen.
Normally you can only see these "effects" when you're in a completely dark room while looking at the GS2 being the only light-emitting source through its display.
Note: The actual purpose of this thread is to educate those people who can't imagine what burn-in/ink marks look like in reality. That's it, just plain visual information.
So I hope this isn't an issue even if there may already be a similar thread
I made some of the photos with the roomlights turned off and others with a very dim light.
The photos were shot using a Nikon D3100 DSLR with long exposure/high aperture settings.

As you can see in the first photo (below), even if the GS2's display shows a completely black image, which should result in a black display (OLED = pixel off) it shows weird marks and still emits a tiny amount of light.
In the second photo I have marked all the relevant weird spots (including screen burn-in caused by grey status bar [see below, marked by arrow])
The OLEDs in the burn-in area seemed to wear out faster because of the static grey shade it was displaying all the time thus resulting in this permanent color change in the affected area.
This burn-in was apparently caused by this theme which I was using for several months. As you can see, even the status bar in a dark grey shade can cause burn in.
A couple of more photos (with different white balance):
See below for photos in full resolution:
Hope this helps in any way and gives those people an impression who can't really imagine how screen burn-in can be caused and how these display issues (ink marks) actually look like when you capture them properly.

Very interesting indeed. Thanks for the great images, it's certainly an eye-opener to one of the main drawbacks of S-AMOLED screens.
Regards.

Roughly about nine months, bought it in October 2011.
Sent from my SGS2.

Hope this is no news? Every AMOLED burns in (like crazy). Been doing that since the first models were on the market.
Every SGS2 has it, whether people say yes or no. On my SGS2 it was clearly visible after around six months. Knew it beforehand so it was no biggie/surprise.

Yeah, also knew it before buying but I never thought the burn-in would look like that so I thought I'd share my experience with the world
While it does look pretty bad on the photos, you can't really see these issues when the screen is turned on with decent brightness, so it's no issue for every day use, but it would be interesting to know how the burn-in looks like if you use your phone for example 3 years.
Still, it looks already really horrible after 9 months of use when you look at the photos. I hope the OLED-technology makes a giant leap forward in the next years so one day these display issues will be a thing of the past.

thanks for the images, i find it disgusting to have that burnt in on a topline expensive phone in short time.
this is my first amoled phone so i dont know what to expect after a year or so, its bad for those who keep thier phones long term, would like to see how the screen is in 5 years time
is it bad when you watch a movie?

Well, it depends while watching a movie. Sometimes I can see the burn-in in movies with a lot of dark scenes, in other movies this issue is not apparent.
Either way..since I discovered this issue, I cannot ignore it anymore which doesn't mean it annoys the hell out of me but still it's a pity to see the phone 'degrading' already after not even a year and spending a lot of money on it.

ya its really annoying especially with my mentality that when I spend a huge amount of money on a tech kit I expect it to give me like 2+ years minimum

Potential camera lens cover crack

So I, like many others, am looking to buy a nexus 4 for Christmas. The lack of LTE means nothing to me as I'm in the UK and can't afford it anyway, so it seems like a pretty sweet deal, however one thing is bothering me...
Many reviews have shown that the back glass can crack relatively easily, and while usually I wouldn't call this a deal breaker, I had a horrible realisation. The nexus 4 is designed in such a way that the back glass acts seamlessly as the cameras lens cover, so if the back cracks, there is a fair chance that the crack could go right down the middle of the camera. Furthermore, like the nexus 7, the back cover actually has components on it, so it may not be a cheap or easy replacement.
I would hate to have my camera ruined because of a poor design choice. So has anyone seen anything around that may reassure me? Is the lens cover a separate piece of glass and it just looks continuous? Or does this seem like a real issue?
The strange seamless camera cover looks cool but may turn out to be a problem.

Good point here.. I really hate putting covers on my phones but in this case... I think I should..

The phone is fairly large as it is, a case just to avoid the camera cracking because of poor design is really disheartening for me

I see what you mean. They should've put a rim around the camera lens separating the two, as they did for the flash...

I wouldn't worry - that glass isnt the camera lens, its a bit of glass *above* the lens. The lens is the little round thing you see underneath.
It a crack goes straight through the middle of it, it would make minimal, if any, difference to photos, except maybe some loss of light gathering.

Wouldn't be the lens that cracks, only the lens front element. In photography in general, front elements can be quite beat up without producing any visible clues what so ever on the resulting images. Check out this web page: kurtmunger.com/dirty_lens_articleid35.html

Apologies I should have made the thread title clearer, I meant the lens cover.
Nice to know it shouldn't make too much difference. I guess if the crack is thick enough to make a difference then I'd probably get a replacement under insurance anyway.

Thanks for the link! Again as with above I should change the title, I didn't mean the lens I meant the cover. I didn't realise it makes such little difference though. Thanks

I was thinking of a similar issue for the screen. I read somewhere that the glass and the digitizer in this phone aren't two different layer on the actual pixels, but one. Thats make the screen more vivid as the pixels are closer to the glass.
So if we crack the gorilla glass, automatically the touch screen will be unusable. Am I right?

that's exactly what happened with the verge's review nexus - in the video they say the back cracked after a fall, and the crack is very close to the camera, pic here: linky
in this case the camera was not affected but the rim of the flash probably makes that area of the glass weaker.
Just don't drop it, I guess

I'd have thought they would for the Nexus 7 to be honest but that hasn't happened yet. At least not easily. But yeah, if it does become a problem hopefully there will be enough pressure for them to start manufacturing and selling replacements.

Didn't even notice that. Reinforces my thoughts of getting a good case.

Any phone can be smashed, that's what's insurance is for.

FYI, the reason they have the rim around the flash is so that it doesn't cause the "flashback" problem and interfere with your pictures. If you've had an iPhone and didn't have a case with the larger camera/flash cutout or the black ring around the inside of the cutout, you know what I'm talking about. The flash can actually wash out pictures. The rim around the flash on the Nexus 4 solves this problem by isolating the flash from the camera lens.

Z3 also comes with very visible digitizer just like the Z2!!

My Z2 has a very visible digitizer pattern on screen not only when seen under the sun but also indoors with direct sources of light. Among a few other faults this was one of the things I would have expected Z3 to fix but this is not the case. While surfing Z3 pictures found a pattern similar to the Z2's.
EDIT: Also wanted to add that my HTC M8 has no such problem there seems to be no digitizer patterns on the screen under any source of light.

For my Z2 this happens to be a problem, when text is being overlapped by these patterns it creates a sort of aliasing effect granted this only happens with white background and black text but still.

I used many phones, and belive me. I have high demand and standards. And dosent bother me at all.
I saw that on my Xperia arc, arc s, Xperia S, Xperia z and now on z1.
No single aliasing made by that digitizer.
You have defected phone, or you have really sensitive eyes.

Trust me the only way the OP sees this is by flashing a flashlight right on it.. i've head a lot of people talk about this but no one's actually affected by it

Yes.. you can see only with direct flashlight on it, or direct sunlight but you must go with that in mind to see it.
Regular use will not see that.

it's no difference than AMOLED pentile displays like the ones found on many of the samsung galaxy phones. almost any display you will always see things if you shine bright light on it while the display is off. of course this is not really a problem because people don't tend to stare at their phones while the screen is off.

While I agree it's not that big of a deal, I was surprised to see it. First phone in a long time that had it this noticeable.

The reason why the digitizer could be seen is because of the no-gap display that they have made between the screen and the digitizer, allowing higher sensitivity on the screen itself (which is helpful for some people), and also reducing reflection/refraction from light source.

If thats they case they are doing a terrible job, the screen is very reflective.

It is supposed to reduce reflection during usage of the phone when it is turned on. Most glass panels are reflective when there's no surface lighting on it.

Not sure of they are doing a good job with that

I've just heard the digitizer is quite prominent on the Z3. A Google search has lead me here.
Strangley, in the past I had a noticeable digitizer in sunlight on a replacement Nexus 4. It's the only phone that has had it, so it was obviously a mistake in the manufacturing somehow as I've replaced screens and had replacement Nexus 4's and 5's. It did annoy me. Yes, most of the time you wouldn't see it, but in the summer, you'll often see it and detracts from what you're looking at on the screen. Looking at a screen in sunlight is already pretty crap in that you can't see it very well. But then to have an electronic grid staring back at you is even more annoying.
This has unfortunately put me off a Z3 and it's another excuse for me to upgrade my N5 to an N6.

I also noticed this on my Nexus 5, and now I see it on the Z3 as well. It doesn't bother me when the screen is on though. Pixels look smooth for me. Perhaps you have your screen less than 50% brightness?

Really not an issue unless you plan on shining a torch on your phone screen...seriously do we worry about something which is small?

I did not notice it, I guess you have to be actively looking for it.

Its not a big deal at all. Screen functions very well inspite of it

Adding my voice to the "It's not an issue" crowd. Seriously, the M8 also had the digitiser panel you could see if you looked under the right light.

[Q] Did Samsung make revisions to the S4?

Hello,
Today, I bought 2 second hand White Frost Galaxy S4's (i9505). Long story short, I was going to just buy one, but both were reasonably priced and I decided I would keep the one in better condition and sell the other one. Reasonable thinking right? They're the same phone after all? Seemingly not.... it seems.
The software on the device is exactly the same, as confirmed by the About section of Settings and the user interface is identical in speed and what not, but here's the thing.
1. The camera lens seems to be different on one. One has a slightly larger lens (At least from looks alone) and it reflects a different colour. The other seems to be slightly smaller. Strangely enough, in my camera tests, the smaller one seems to perform far better than the bigger one, which is a worry.
2. The display on one is less 'vibrant' than the other, both are more vibrant than my Xiaomi however.
3. The one with the 'better rear camera' seems to have a worse front facing camera that seems to seems to overexpose photos more when held in the same place as the other S4.
4. The white frost texture is different. On one, it's very faint and you can just make out the little diamonds that make it up. The other, they're more clearly marked and visible.
Both phones look identical from a far, but it seems evident that they have different hardware or have been built differently. They're both I9505's though and both seem to have the stickers, boxes and what not to prove it.
Has anyone else had this? I will upload some photos when I get chance maybe tonight.

The better camera, slightly purple hue, no ring and more gap between the lens and the edge.
The worse camera, green hue, a ring around the larger lens and smaller gap.
Is it possible the second one is an aftermarket sensor? Surely not? Neither show signs of butchery.

Attempt to put both units into download mode. Tell us the results.

Using e.g. 2 different camera sensors for the same model is not uncommon. Didn't Samsung admit recently, that they're using both Sony and Samsung camera sensors for the S6 ?

Yes they did, but the S4 never had the issue with camera sensors, or the people here would have known about it in 2013.

OK, Thanks for this useful piece of info. I'll have a look what this turns up. It's night now, so going to see if the cameras react differently in lower light conditions. The unfortunate thing is, one of the reasons I bought the S4 is because I know it has a blisteringly good camera. I've been told it's still one of the best even 2 years on, which is why you can imagine I was so disappointed when I realized one seemed to have a better camera than the other. I've stupidly let the battery drain on the one with the good camera, so I can't test the low light conditions to see if it's better.
I've used your code, sure enough, the firmwares are different. Does this mean I could load a better camera firmware or perhaps the phone is due a standard Samsung update? Both are still on 4.x:

Green Lens:

Very possible. I've been doing some research, apparently the Purple sensors are made in China, the Green sensors are made in Taiwan, both supposedly to the same spec and should provide identical results, but clearly that isn't the case, the purple sensor seems to do a much better job and this disappoints me. What's worse, I've already fallen in love with the S4. It's exactly what I wanted from a phone since getting rid of my Nexus 4 which the lack of an SD started to get on my nerves.
That may explain the camera differences I suppose, but it doesn't explain the other differences. Again, one has a slightly different screen, it's certainly less vibrant. Not noticeably so when used on its own, but certainly when next to the other S4. Could that be caused by use maybe or is that different hardware? Further to that, what about the one with the worse front facing camera. I've looked at it closer and it seems the front facing sensor is ever so slightly higher than on the other S4 which means perhaps the light distribution isn't so even? Also, those other optical sensors don't seem to be the same, slightly higher it seems? Perhaps this one has had a new screen installed.... nightmare this is seeing as the one with the possible aftermarket screen has the camera I prefer. Wtf?
Also, while all those things can be explained, rear camera perhaps a different sensor, screen perhaps slightly different due to use, different screen explaining front facing camera.....
It could also explain the white frost thing, perhaps the aftermarket screen has a slightly different white frost look. I guess it would be wise to keep the one with the OEM screen and not let the camera thing bother me too much...
I might place the device in a tripod and take a photo of the same thing and see how it looks

Just ran Antutu,
1 device got 30375
other got 30124
so realistically, they're both genuine, but I'm getting the impression that perhaps one has had a replacement screen (maybe not a very good one). That'll probably be the one I sell, even if the sensor is better on that one. I think with the green sensor, you have to focus more carefully. Not ideal. I can do more tests I guess.
