Reflections on Photo - Xiaomi Mi A3 Questions & Answers

Hello, I have a question about night photos. Often with night photos reflections / dots appear as in the attached photo (dots on the right in the sky). The picture does not come from my phone, but the symptoms are the same. Is this the normal behavior of the optics under these conditions or something wrong with the camera? View attachment 4947257

clean the camera with a soft cloth.

You're shooting when it's below dew point. Moisture can condense either outside on the camera glass surface or inside on the lens. Depends on temperature gradient from warm to cold, or from cold to warm.

It's lens flare, perfectly normal. This phone seems to be a bit more prone to it than it's usual. If you move the phone, reflections move around the picture and under certain angles disappear completely.

Interference pattern on camera with fluorescent lighting

Note: THIS IS NOT A PINK SPOT POST
I noticed by accident that my camera generates what seems to be a interference pattern under fluorescent lighting. This interference pattern appears as vertical bars if the phone is held in portrait orientation or horizontal bars if held in landscape:
I then changed my light to incandescent and still saw the pattern:
'
With light off:
These pictures were taken of an off-white wall lit by a combination incandescent/fluorescent light using the back camera of my i9100.
Furthermore, the bars gradually progress from the left of the screen to the right (held in portrait).
In summary:
Vertical pattern of evenly-spaced alternation between dark and light
Pattern progresses (moves) from left to right.
Pattern is augmented by fluorescent lighting, but is present under incandescent as well.
PDA: I9100XXKG3
Phone/Camera firmware: TBEC28/OCEE09
Bonus points for noticing the dead fruit fly in both pics
Absolutely nothing extraordinary or strange. CFL lights flicker at mains frequency. If your camera's shutter hits a similar frequency, you'll get patterns such as the ones demonstrated.
It's an electronic (progressive) shutter. Get used to it
(PS: try it on a rotating bike wheel)

I've noticed this when I first got the phone. It's as orcinus says it. The some lights flicker in a frequency that is made visible on the camera.
When taking a picture, turning Anti-Shake ON reduces seeing it on screen but it's pretty much not noticeable when you view the resulting picture after taking it. When taking a video i've noticed its more prominent when resolution are 720 or 1080p but much less when below those resolution.
I've noticed this too, I think this is pretty much expected on mobile phone camera.. Some DSLR's even have get this effect, I also get pretty badly saturated images under the said lighting conditions.
Is there any settings you can change on the phone to stop this from happening??

No there is no setting for it, All u have to do is avoid fluroscent light
@b1ind
I tested my samsung galaxy s II / beloved s advance on different light sources (magnetic ballast) :
-Fluorescenc lamp
-HPS (High Pressure Sodium street lamp)
-Mercury street lamp
-Metalhalide
-Polish metalhalide's prototype (LRJ).
This lines were there all the time. It is caused by phisical rights of electricity. Every light source is blinking but suuuuuuuper fast. We cant notice that , but cameras can. And this is the result.

Circles in pictures taken with flash on...

This just started recently. Anyone else experience this or know what it is? Pics without flash are fine.
I've searched and can't find any info on this.
PS...the circles are in every pic with a flash. They aren't a reflection off of other lighting around the area. I can take a pic with no lights on and these circles/rings are still there.
Thanks!
Can you see any physical damage on your lens?
Was gonna say dust but that's too big for a dust particle....
It might be them energy orbs when there's a ghost nearby like you see on all those ghost documentaries. And I may be right, on the right of the picture there is a figure in one of the circles!
But anyway, have you tried taking out the back door battery cover and take a picture then to see if the circles remain
take a picture with the flash on AND the lights on and see if it still happens. If it does then there is probably something wrong with your camera/camera flash (ex. flash leaking into camera lens somehow). Also try taking a 3d picture with flash.
Hope this helps.
Yep, happens in daylight as well. no apparent physical damage to lense or cover. guess my camera is borked.

White Glowing in Pictures

Every time I take a picture that includes white, the white looks like it is glowing.
Any ideas on how to fix this?

Check your exposure settings, you might be set too high. You can long press on the shortcuts at the top of the screen (assuming you're on stock) and add exposure to the shortcuts if you want too, so you can change them easily. I assume you're not using a flash, right? That could be the culprit too if the subject is lit well enough.
Could be your case also. IF you have one of those clear cases they tend to cause the camera to do that when the flash goes off.....not with all but some...just an idea
Turn the exposure down.
Mine looks exactly like this if I haven't cleaned the lens in a while. All the saltwater in the atmosphere here depositing junk on the lens.
First try different camera apps..If you see the exact light spots in different camera pictures..I would pull back case off there's 9 little screws..and use a wedge tool atounf the chrome casing and the glass..pulls off easy..abd clean the back of the lens..very easy to do..sometimes dust gets in there from the speaker and blows around...

Anyone else with very bad lens flare?

https://www.dropbox.com/sc/w3aflekki0thqhj/AABqSYnVucDo-QVQeqYJeb2Ba
Anyone have this wonderful issue? I used my note 8 in the exact manner and no issues. No case on the s9+ or anything that could cause this besides a possible hardware issue or I received a lemon. Please check out your camera's and let me know plz. I hope it's just my phone
Yes! Under certain angels it's unbearable. Even had to check if I left some of the film on there, nope..

Thanks for the response. I went back outside to take more pics and I noticed the camera module was very reflective. It was like i was reflecting light with a little mirror. I grabbed my note 8 to see how that module's reflected light. At first i barely saw the reflection. Then i had to really put the phone at a major angle to get a brighter reflection. I think the camera module's aren't positioned correctly or designed correctly to avoid recieving the sun's rays in an improper way which then produces these crazy sun rays in the pics. My pics were taken mid day so the sun was kinda just past it's peak height. I took more pics later on with the sun lower and couldn't recreate the crazy flare. This is a deal breaker for me. Do you plan on keeping yours? I called Samsung and they weren't any help. They told me to return the phone and order another if I wanted.. this sucks
Damn. That's some crazy lens flare. I'm heading to Hawaii next week, and I'll be taking my S9+ (if it shows up on time). I hope the lens flare isn't going to ruin all my pics.
My Note 8 does it at certain angles, I just use my hand as a lens hood on the side that the sun is coming from.

Yeah, it's bad. Just communicated with Samsung Support on Twitter and they blamed the dual aperture. Suggested I try different angles and tap to focus. Smh. Guess enough people will have to complain before they realize there's an issue.

lol Well, if it is the dual aperture, it's a design/manufacturer flaw.
They basically just fed you the "You're holding it wrong" Apple reply, lol.
Thought it was a rainbow. How did you get it to show? As none of my pics have that but it hasn't been sunny here
Yeah the 1st photo I took outside had lens flare. I'll deal. I got the phone for the stereo speakers and speed. Not the camera.
While it may not eliminate all of it, you do have something on the outer glass covering the lens. It needs to be cleaned with a lens pen. That's what's causing those little o shaped artifacts. Because of the tiny aperture and very wide (F 1.5), these objective element must be kept optically clean as if it were a laser optic! That's exceedingly difficult since its exposed. My suggestion is to purchase a lens pen and keep it with you if the best quality pictures are important. One can really see this at night when capturing dark scenes with bright pinpoint sources such as headlamps and streetlights, etc.
My biggest issue with camera phones (they all have it!) is the internal reflections producing ghost images. It's really apparent at events (i.e. concerts) with multiple bright points of light. Bathes the image in little blue-green dots everywhere.

It was all from the sun. I had issues with my pics no matter which way I stood.

Was the flare similar to mine?

The pic with the circled artifacts was the first pic I took. The lens was clean toothe best of my knowledge. The following pics didn't have and of those artifacts pop up. Nevertheless, I'm concerned that there is a design flaw. I've owned many phones and have never had such an issue with taking pics with the sun. I was tweeting Samsung support and said the light penetrating into the lens was the reason for the terrible pics. Idk.. the phone is very new so we'll see how many do or don't come forward with this issue. All I know is the afternoon sun was just at the right height to cause the angle that the camera didn't agree with.
It's possible as with wider apertures and very bright out of frame light sources striking the periphery of the aperture you will see this. This can't be avoided even with pro gear hence the use of bulky hoods.
The idea of a two step iris, even in its rudimentary form, is a new frontier for mobile devices and this could be a glaring limitation if not annoying. Just as when driving one uses a visor or their hand, you may have to improvise and provide some shading to limit these artifacts.
Used hand as a shield
Well, took some more pics and the results are terrible. I even had it in video. I used my hand as a shield and away went the lens flare. I even rotated the phone to were the modules were on the opposite side as I normally use the phone during picture and video taking. I think that made it worse. I'm just disgusted.
Another example of me shielding the sun.
Sorry but they were flipped during the upload process.

Thank you for sharing. The speakers and speed are great! I messed with the phone before it was released and thought the speakers were ok. When trying them when I recieved the phone i was very impressed. I take a ton of pics so I don't think I can tolerate this camera issue.

Camera Landscape not Level

So I love this phone and the camera, but I'm having a strange issue where landscape pictures aren't level. They're all slanted. I've tried multiple times to make sure I want holding it at a weird angle also. As another resort I set my phone on a leveled surface in landscape, took a picture of another leveled surface, and it came out slanted.. Again.. Clearing data for camera did nothing. Any ideas? It appears to be about a 5° tilt.
Sounds like a manufacturing defect.
Post a pic.
