New issue - camera defect - Google Pixel 3a XL Questions & Answers

After degraded battery my one year old 3a XL generated new stuff to rouch my nerves...
Shooting mainly blue sky found a dim spot on one and the same place. The reason why it wqs not detected is its harder to see on more complex scenes.
Tried to clear the lenses ... nothing.
I've done a picture to illustrate the issue - attached.
Anyone with similar issue? What do you think it is - dust, defect on lenses / sensor ?

looks like dust on the sensor. Unfortunatelly I don't think I can open it and clean so I will rely on software correction

[Q] htc desire camera problem

hi,
few days ago I dropped my desire on the ground and since then I have this camera issue - I cant focus objects that are more than 30 cm far from camera - it's all blury. in close it works very good, like it should.
all that i could figure out is - that focusing mechanism stucks at certain point and cant focus objects in far.
i wanted to ask if anyone has had similar problem?
is this camera defect repairable or should I buy new one? and are cameras for desire sold seperately anyway?
Thanks in advice.
The Camera isnt like a digital camera, there is no Optical (moving/mechanical) zoom, its all Digital Zoom, cameras are repareable and you can proably pick one up off ebay
Oddly enough when you take the picture and see it on the Phone/Computer is it blurry??
http://content6-foto.inbox.lv/albums137027374/martinzg/htc/focus.jpg
in title there is link of the example of what I get from my camera
Oddly enough it looks like tap to zoom on the keyboard, but with things in teh distance they are slightly blurred as an out of focus camera effect, oddly enough have you tried flashing the same ROM again??
Additionally you can always look at the repair option just as a safety net, ebay should have cameras (might be hard to spot to start off with though) and you can always look to the shops for repair info/advice, just dont tell them you dropped it like i did, as it appears warrenties dont cover accidental damage (damn Apple Store)
there is no changes when I take photo with flashlight - it's still blurry.
so, do you have any idea why pictures in distance is out of focus?
couldnt it be some kind of mechanical defect?
I have the exact same issue martinzg.
Will focus up close but not on anything over a foot away.
Contacted HTC this morning waiting for a reply.
I have the same problem here.. any news?
exact same problem here
old post, but I have the same issue !
Anyone a solution ?

[Q] Camera: Skin tones have excessive redness. Can camera be calibrated?

I've had my HTC One X for almost a year (via Orange shop here in the UK). I've only occasionally taken pictures with it, but I've recently started using the camera a lot more recently due to a new family arrival. Something I have noticed is that when people are in the photo, any reds or pinks in skin tones (faces, hands) *really* stand out quite excessively.
I have searched on this topic and I've found lots of references to an overall hue / tint problem occurring with various colours. However, this can't really be described as an overall tint. It's almost as if there's a horrible nonlinearity with the response to reds / pinks or something. If I take a picture of a face or hands, the reds in the fingertips or cheeks stand out very excessively.
I *think* it's okay with the front camera, but I'll test more to confirm that.
My camera settings were initially as default. I have tried fiddling with the various settings, and setting the saturation to -1 does help the problem a bit. But decreasing the saturation of course reduces the saturation in all colours and I can still see that the response to red is still excessive.
I haven't dealt with HTC before, but from all the horror stories I've heard I'm not sure if I want to go through the pain of returning the phone.
Two thoughts:
- Is there any way at all that the camera can be calibrated on an individual colour basis? I'm guessing this would be something only available via a custom ROM if such settings existed. Using a custom ROM could be tricky for me because this would I assume mean losing the Orange Signal Boost app, which would be a pain.
- I've noticed replacement rear-facing camera assemblies aren't too expensive on eBay. I'm an embedded electronics engineer so I'd be quite happy to disassemble the phone and fit a new camera. The real question, though, is whether the problem I have is actually within the camera itself. For all I know, some kind of factory colour calibration could exist for the cameras on the motherboard, meaning replacement of the camera would be pointless. If on the other hand the calibration is all within the camera module itself, perhaps this is worth a shot.
Any thoughts please, particularly in relation to my last point? I'm still considering obtaining a replacement rear-facing camera from eBay and swapping it over. However, before I go ahead and buy one, it would be very good if anyone out there can actually state from experience whether or not colour reproduction problems are an issue with the camera module itself. Or, to put it another way, has anyone ever replaced camera modules and found colour reproduction to be different between them?
You viewing these pictures on your phone or in PC?
If you open the picture in gallery you can edit the levels, contrast and the like.

HTC one x has bad colour reproduction, ICS was decent but JB literally stuffed everything up.

Flecks of "dust" in photos

There have been numerous discussions on XDA and elsewhere about issues with Xperia cameras, specifically what looks like flecks of dust on the images.
It was my theory that such dust would have to be directly on the CCD in order for it to appear as sharply defined as it is.
To test this theory I removed my camera and using an exacto knife and a steady hand, opened the camera to expose the CCD directly. Then using a cotton swab and some alcohol, wiped the surface of the CCD itself.
After reassembly the dust specs were still evident in the same locations.
It is my opinion based on this that it is not worth the effort to do what I did. You will be better off replacing the camera entirely. Or letting the phone slip from your hand while you are mixing a load of cement.
Possibilities:
- the flecks are under some protective surface on the CCD
- the CCD was manufactured with the flecks already there
- pixels in the makeup of the CCD have gone dead
- etc etc
I thought it a good idea to post this so someone else would benefit and not waste time with a futile effort.

I think its software related. If you go to video, point at something white so that you can see the black dots, then wobble the phone a little. You will see them jumping around on the screen as the camera tries to focus. I'm not sure what it is, but its definitely not dust.

Your images taken through camera will contain noise during bad lighting conditions.The images taken with my phone on bright sunlight are good and do not have any noise.Sony should take care of this atleast in upcoming models

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?

And Honor 8x does the same? Thought that the camera lenses cover has some reflecting residue like oil etc...it is strange.

Yes, Honor does the same. Actually I've just checked LG V30 and Huawei P10 Lite, and it's almost the same.
I'm kinda shocked I haven't noticed it before.
Can you please check on your phones?
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.

Question Heavy lense flare in night shots

Does everyone have these extreme lense flares / reflections on night shots? Don't think I've ever seen it this bad... Hopefully they'll be able to improve this through software updates
Lens flare is a big problem on the P6P even during the day when the sun rays hit at an angle #Won'tFix Unfortunately it's a lens problem and can't be fixed with software
If not fixed I hope it can be reduced... Is extreme in some cases
I haven't noticed a single flare at all with night shots the street lights or even in doors in direct lighting, sometimes at a certain angle in previous phones I have had it but nothing on my p6p
Yeah, it's bad.
Not as much as that but I do get that.

Yeah. I went to a festival here in Korea called the lantern festival, so it's held mostly at night and I had a buncha shots I had to throw away because of the flare, and a lot were hazy, I thought maybe it was my camera lens being dirty but the next shot was fine after the processing.
Haze and lens flare

45 degree turn from the previous photo, no issues
One of the better shots but too much HDR
I'm having massive lens flare on my pro like you op. other photos in this thread are acceptable imo. I can't tell if there's an issue or not. it's horrible, no matter what street light or x-mas light its pointed at. and night mode shots, forget it. too bad there's no way tom compare shots unless they are side by side.
running the latest 8.4.300.xxx18 version for the camera app. it drastically fixed front camera preview. so not sure if this issue will be fixed or if my cam is effed (no lens protector and tried it with no case also)
Come on guys when you say you aren't getting any flare. It depends how close you are to street lights. It doesn't happen at a distance from strong street lights. I get it on P6P and am sure you will if you try it. It is not faulty as I had same issue on S21 Ultra main lens but not as severe. Here's a shot I took
I didnt notiece it much. Maybe because of snow

Need to be much closer
Here more examples closer to light and further away
My opinion is, that P6P has problem with the flares, but main problem I see is that Nightsight tries to lighten up the scene, and thinks that the flares are shadows that should be lightened up. But I admit, I pointed my pixel to light source and id did show some flaring, but not as much as your photos.
all phones do that. Even my s21 ultra and my gf's 13 pro max

Nah man, maybe to some degree, but this is ridiculous. I still have my previous phone, Oppo Find X2 Pro, and it's not even nearly as bad there. I'll post some side-by-side comparison shots soon
P6 (Pro) has heavy lens flare, it's a known problem. Hopefully Google can somehow tune it down with software updates.
What also helps is making sure that the lens is pristine, meaning you need to make sure its properly cleaned before you make photos. Even a little bit of smudge or dust or something can cause lens flare. Hopefully that means it's a software thing-y.
It's got absolutely nothing to do with dirty lens, that purple lens flare is light bouncing off the lens or sensor inside.

Are you talking from experience? Having the camera bump cleaned does help with lens flare, just try it out yourself. There was a reddit discussion about this and people were adamant about it, I tried it out and it somewhat helps.
Also, your "logic" is not quite thorough.
If there is dirt/smudge/whatever above the lens/camera, of course that could cause lens flare, since that will reflect/redirect light. With a rough surface, reflected light rays scatter in all directions.
For reference
I get lens flare when using Canon L lenses (and one of them retails just under £2000) it is the nature of the beast shooting into bright sources of light though a lens.

Correct, some degree of lens flare is almost unavoidable. The P6 has, however, relatively heavy/often lens flare present - that was not present (as heavily) in previous Pixel phone iterations/sensors. Hopefully Google can somehow tune this down. It's distracting and most often or not ruins an otherwise great shot.
