camera problem s4 mini 9192 - Galaxy S 4 Mini Q&A, Help & Troubleshooting

hi
i have a problem with my camera
when take a picture with flash in very dark environment like at night beach or in party or room, in the left side of pic see a burn like noise.
i take lot of pic and I observed if the object is located at near distance at approximately 0.5 meters, for example, the image has not any problem But if the object distance is greater pics is noisy .
but when room has enough light with or without flash pics don't has any problem.
I used stock camera program and many other programs, but the results did not change.
now i updated my rom to last version ( I9192XXUAMI1 ) and tested again but The result is like before.
Someone has a problem like this?
Somebody has a solution?
i creat like this tread at sommobile.com
you can see my example pics in beach at night and dark rooms

i have the same issue with flash, but i thought the case i have the phone in is reflecting the flash light into the camera incorrectly.

thanks for reply
I'm pretty sure the problem is not from sensor and the problem is flash reflected light and hope Samsung could solve the problem somehow.
Sometimes the problem was ruin the picture and it is very annoying.
i want know all of s4 mini phones have this problemconfused:

well i think i know how to solve this try taking photo in case of removed back cover if there no noise this will be because of the color of back cover i think in with white ones so u would try black back cover or dark one hope to help

I removed the back cover, but it didnt help at all, it appears in the left top corner from distance 0,5 meter and with larger distance is the purple light more intensive.

i have also s4mini and same problem

Maybe reason
Hello
i have same problem -> purple tinge on night photos with flash on my SGS 4 Mini. I thing its same problem as on Z1 compact = bad housing, which transmits light. The day after tomorrow I borrow a black cover. I think it will be better.
Please confrim if you have WHITE sgs4 mini as me.
PS: I tested to cover the flash with sticker, and result is in attachment ;c)

Try this camera app: https://play.google.com/store/apps/details?id=com.almalence.opencam
Another user had similar issue, despite I also told him take the back cover off. I than recommended him to try the above program and works. Give it a shot.

Same here on my GT-I9195. An annoying glare from the flashlight's side, when I shoot in almost complete darkness.

HTC Touch Pro 2 Camera bright spots.

Hi all
I faced a very strange problem. Let go of the dead pixels, I am talking about the camera previewing the image very clear and OK. After the shot has taken place the photo is decorated with bright spots (red, blue..etc) sometimes 2, sometimes 5 it depends -I dont know on what. They are not present in the real view ofcourse. This is not dead pixels as they move and grow as I zoom in to the photo..Any similar encounters???? Or Advice. By the way, this is my second exchange from amazon. I asked them to send me a third unit.

Thank you for your reply. Please find attached the photo with the problem previoiusly mentioned. You can see the bright 2 spots in the middle and to the right of the picture if you enlarge it they will appear clearly. Those 2 dots are not present in the real scene nor pre the shot in the view finder. After the camera takes the shot they appear in all pictures.
Here's a snap I took with the camera right on top of a black surface. You can see there's a couple of spots near the bottom but certainly not as bad as yours. It probably happens since the camera is not made for taking black photos and as it struggles to focus, it is "tricked" into thinking there's some light there where there's not. But anyway, if it bothers you to the point where it effects your normal photos, then you should return it.

Camera question - Washed out pictures?

Hey Guys....thanks in advance for any replies...
Can anyone give me some tips on how to take decent pictures with the Evo? In most cases I am taking pictures in dimly lit restaurants or bars (no comments please, heh heh) and most of the time the pictures are completely washed out due to the flash coming on and lighting up the subjects faces like a Christmas tree.
Does anyone know if there are settings, other software or any other tips that can be used to help me take better pictures??
Thank you!
From the camera app,there is a tab on the left side in landscape mode. If you slide it open, choose settings, then brightness a slider will open. I've found that in dim to dark conditions, best results with flash on are with the brightness set to around -2.

Theres an old photographer's trick, not the most elegant of solutions but putting a piece of scotch tape over the flash will help diffuse the light and also get rid of the harsh shadows from the flash.

Honestly this has started to cross my mind too. The two flashes 'sounds' like a good idea...but they are WAY TO HOT for a close up (within 6 feet or so). Now they did actually work pretty well at dusk for a test shot about 12 feet away. (So that should tell you they are too bright for close work)
I am thinking of maybe taping just one and testing.
But you could use scotch tape as posted, because the frosted look of the tape would help diffuse the light. (Remembering it will diminish ability to flash far away.)
Have to start treating this more like cameras now...they are going to require more than point and forget.
Idea
I asked the same question a few weeks ago - why doens't the EVO do light metering.
One though would be to use a LED application to turn on the LED light - maybe on low, and don't use the flash on the camera application? I know a pain to do (and a loss of coolness points) but might work?
if you really want to be photo savvy go to a photo store and get a sheet of diffusion gel, and just place a small cut out in between the flashes and the battery cover. also always shoot as low as you can go with the ISO, the problem with the EVO camera is that when in low light situations it switches to a high ISO, but it doesn't factor in the fact that the flash is going to go off, so when the flash goes off, the high ISO coupled with the strong flash means super overexposed picture. so either leave the camera at iso 100 or 200 and try shooting that way or try the diffusion i stated earlier.
the camera is just very badly coded. for instance what the camera should be doing is lighting the flash to focus, read exposure and compensate, then take the picture with the proper level flash. as it is now all it does is try to focus completely in the dark, then just flash the flash at full power while its taking the picture. it really is a terribly coded camera.
its like the people over at HTC basically just added the lcd's just to add them, i mean we already know that the LCD can be used at various levels of intensity...its a damn shame...
Are there no apps out that improve the cameras function? i figured there would be.

Hot Pixel Camera Problem?

Hi everyone, just a few minutes ago i was looking for a completely black wallpaper and it came to my mind to just put my finger over the camera and take a pic, as soon as i put my finger over the lens i saw a few red and blue spots on the screen...i then put it over a black cloth and i could still see the red and blue dots(look like dead pixels but on the sensor?) its best visible when camera is set to 8mp. I am just wondering if this is normal or if i have a faulty camera..the dots dissapear as soon as there is some light i will post a pic in a sec. Please can anyone test it out by turning on the cam set to 8mp and put your finger over the lens so its completely dark wait a bit ( 30-40sec) and look at the screen.
Edit: Also when you put the exposure to max you can see it even better.
Did a little research and it is called a hot pixels.
Hi,
At 1st excuse my english please!
You dont need to be afraid of this, this is totaly normal an youre camera is ok!
The sensor generate colors from RGB (red, green and blue) and what you see there is no more then the try of the sensor to put colors in the dark!
Greetings
Alef
Yes but they are on the same spot every time and they are flickering, the only way you can notice it is in a dark room and when you put somthing over the lens so its completely dark then i get flickering hot pixels on the same spots. Please can anyone else try this and let me know if you see it on the display/viewfinder.
A lot of sensors can suffer from that, that's why normal cameras offer pixel mapping to disable hot pixels. Unless you see those spots show up in final images I would say don't worry about.
It does show on the final picture. That is why im asking people to check if they have same thing.. if every one has it i wouldnt worry about it but if not i will go exchange it while i can. Its bright flickering white, red and blue dots. Looks exactly like a stuck pixel and not the rgb noise ones that are visible on the whole screen.

Hi,
I found an explanation for this:
The CCD-Sensor interprets residual voltage (<----Hope the right word! ) as brightness information what results in those colored spots!
As I said, its totaly normal!
Greetings
Alef
If you take a picture in a dark room, the camera will boost the gain in order to try to take a decent picture. It will boost the gain until it sees enough content in the image. The darker the room, the more the gain will be boosted.
By covering the lens youve removed all of the light. The camera is therefore boosting the gain as much as it can until it's picking up what is effectively noise in a few of the pixels (some will always be more noisy than others). This wont have any noticable effect on a picture taken at normal light levels.
Thank you everyone for the explanation

I actually noticed this, too. I thought I had a dead/hot pixel on the screen, but it only appears when it's on viewfinder mode. It doesn't really appear in the image taken itself (or maybe I just don't notice) so I never really minded it after the initial discovery. Glad to know this is just normal
I'm noticing this too.
except differently, i'm not seeing individual spots, i'm seeing hair-like artifacts.

any suggestions?
Hmm that looks really bad.. did you solve it?
You will have to send the phone where you bought, I think it's a manufacturer's faulty

Flash Bleeding: is Sony going to something about it?

Hi guys,
I have this phone for 3 weeks, and I think it's a great phone but simply can't stand the fact that when I shoot in low light condictions I got that flash bleeding simply destroing picture quality.
I've used the marker trick, but after a week or so the coloring has gone away and I had to do it againg.
Guys, so frustrating you need to paint a 400£ phone once a week come on....
Will Sony do something about it, or they consider just enough they've said "You're shooting it wrong" like reportend on Talk Sony Mobile forum?
Will they just tact as if nothing has happened and fix this on Z2 Compact?
Always loved Sony for the way they are different form Samsung, Lg etc. but really disappointed this time...
Ever heard of HTC One purple tint issue on camera? I'm pretty sure it's a hundred fold worse than this camera issue and up to now HTC didn't provide any official recall or fix for this problem. AFAIK this issue only shows up on situations where an image would be worthless. I mean who takes picture of a black sky without any objects? Or takes a picture on a empty dark room without any focused subject nor takes a portrait picture of an object which is on a far distance than normal. All I can say is take it easy... Just use the camera normally and you won't encounter the issue. I've done low light pictures from the compact already from night concerts, Selfies on night, low light shots on some friends and stuff and I haven't encountered the light bleed issue. The only way I can reproduce it is if I take a picture of the sky, taking a picture of something a few meters away from me or taking picture on a empty dark room(ghost hunting? ).

My HTC One and also a friend of mine's were replaced because of the purple tint camera issue. That was a hardware issue with the camera itself (or perhaps the assembly process) on the first batch, this unfortunately is 'just' a back problem probably due to the last minute change from glass to plastic and not the camera itself.
we can only speculate. They wont fix it with a fw update. Changing the back panels are the only thing sony could do. are they gona do it? i dont know, and i dont think so
ps: i also had to repaint it, but now its fixed. the paint stays longer on the second or third time that you paint it.

i disagree. yes this bleed is a lot worse when taking a nightsky pic, or in a complete dark room, wich are things that you probably wont do. but you can also reproduce it under situation that you might come in the future where light is low, but not complete dark.

Yeah,i had blue tint in 2m my dark room and on potrait of guitar in dark pub so you can reproduce it quite easy(painting did the job after though)
Ok so I guess the color of the phone does indeed matter. Since I really can't reproduce the light bleed easily without that much effort. Also with HTC One issue. For previous owners we know that it took HTC almost a year before recognizing it as a hardware issue and keep denying it for months right? And yeah they didn't provide any recall. They just simply say that it's a software issue and will be fixed on future updates and is only fixing phones that are sent to their service centre.
on HTC One X we have green tint when using flash , but it can be fix by a software http://forum.xda-developers.com/showpost.php?p=36287923&postcount=1
No light bleed here but I have black.

Actually my HTC didn't have the problem at first, it only started after the 4.3 update. Then I just waited for 4.4 in hope of a fix, obviously nothing happened so I sent it for repairs. My friend's had this issue since the beginning on 4.2.
Anyway, I think we are being a bit off topic here

I also plan to buy the black one, but all users are reporting flash bleed even with that. Also, I don't think the leather case would change anything, because the light finds its way into the camera through the plastic back, which the leather case can not prevent. Just to be sure, could you try taking those photos without the leather case?
I really hope that Sony fixed this (at least quietly in the background). When did you purchase it?

Will try........overall am very pleased with this phone and its cam, I do own a 808 and spate of SLRs so this one is competing very well with them. Only thing thats needed is RAW support and more controls in manual mode, truly lacking compared to my 808.

Or they just don't want to make it official/public, so that they don't have to replace all already sold models. (As in case of the earlier mentioned HTC issue)

Duplicated light source / ghost lights in photos

Hello,
Today when taking photos I've noticed that light sources like lightbulbs and chandeliers appear twice in photo. It's hard to describe, but attached photos should clarify what I'm talking about.
I've checked on other phone, Honor 8X and it's same.
And here's my question to you: do you observe the same behaviour, or my device is flawed?

I don't know if it's worth using warranty with my Note 10+ if it's the general issue.
I took a direct photo of my desk lamp and there's nothing wrong, I'll try again later tonight using different angles/sources.
I googled it and this problem is widely commented on:

Thank you for the link. So it seems like this can be considered "normal".
However I'm still curious what will be result of your tests. Please share what was the outcome, whether you were able to reproduce this.
It depends on the angle, sometimes you will see this, some times not, I have seen this in dedicated cameras as well
Thank you for your response.
As I'm testing it more, it seems very hard to take photo without ghost lights when not pointing straight into light source, attached few more sample files.
Maybe I'll get over it, if not I'll give it a go, and use warranty, they'll do something with this or not.
Hello,
That's amazing to see this post today, just the day i noticed exactely the same.
I noticed that when doing a video test, through windows stores (the room was in the dark, light going thru the little holes in the stores). I had exactely the same kind of little lights reproduced in the left quarter of the frame.
I thought it was due to the shape of the lens, some kind of light reflexion on it, but now i am wondering because that is the EXACT same thing as your description.
I would not send to warranty... since i had exactely the same 'problem'. I believe it is due to lens design.

I believe you have the same, but don't know how often you see these lights.
I can understand this can be seen in some conditions, but as I'm testing it more, I almost can't take any photo without it.
I've looked through YouTube reviews with some night shots and can't see it there.
Attaching last two samples, to not spam this thread, as maybe I'm now oversensitive on this
I'll go to the store today, and see what they'll say.

Went on tonight to my favorite night photography places and the full moon was the perfect source of light to look into the "ghosting" thing. It's really easy to see what's happening with the light when moving the camera around its axis. Note 10 has a rather thick glass covering/protecting the lenses and the light entering the camera is being distorted by the inner and outer surfaces of the glass plate depending on the angle of entry.
I was having really boring Sunday today so I'm glad I found something to do because of that, and I even made a little drawing using the S-Pen(love the s-pen!) to illustrate directional changes of light while entering/exiting a medium of different densities (air/glass)
We know that light will get reflected by a glass at certain degree because of different density between air and glass. Basic physics. Our camera is made of multiple layers of lens with variables angle. So if 99% of light goes through the lens, 1% get reflected. We won't see it for normal light. But if the light source is very bright, even 1% will be visible on photo.
That's my hypothesis.
Happens all the time when facing a lamp light directly, with wide and zoom lens. But seems to be less visible with ultra-wide.
This looks like an internal reflection within the camera it's self.
Internal reflections are common on multi-element lens.
You pay big bucks for coated elements and engineering to suppress this effect in pro lens.
Internal reflections can also happen between the cmos sensor and any of the internal optics.
In the case the cover element is a prime suspect.
Lol, you can thousands for a pro shooting system and you will still find this.
