Question Blurry spot at the fingerprint sensor position - Xiaomi 13

I just received the global version of Xiaomi 13 yesterday. When using it in low light conditions at night, I noticed a blurry shadow appearing at the fingerprint sensor position and the bottom right position of the selfie camera. I'm not sure if it's normal, do I have to take it for warranty? Thank you, everyone. (I'm sorry if my English is not good)

It's strange that I don't see that blurry square anymore after a day. @@

[Q] i997 Camera Pink Spot

My infuse 4g, camera photo showing the middle of a slight pink, do not know why, the friend know the solution
Yeah i film that saaweeet pink spot to..but i will never post it to youtube or whoever..lol.....i am good with this cam.one day it will be able to xray you and give us all cancer like our t.s.a.
Most phone cams have have this problem due to the very short optical path and the type of infrared filter used. Usually, they are calibrated for daylight. So, if you have a significant problem under daylight, I think your camera was not calibrated properly. With indoor lighting, it is to be expected.

How to take best picture in very strong light condition with HRD+/HDR+enhance

Hi all
when i take picture of my yard in bright sunlight, when i open the camera app and choose the HDR+on/HDR+enhance with autofocus, the yard in the camera screen is over-exposure, and when i take with HDR+on/HDR+enhance it doesnt change any thing when i saw in the camera screen, it quite strange, because i thought that function should process the over/under-exposure to keep the best detail, highlight and make the picture as real as it can ? what do i miss ?
and one more thing
when i tap the screen to focus to the sky, all around object and bright become darker and when i tap to the yard the bright around is brighter but the sky is lost detail of cloud and the building, it's normal ?
sorry cause i'm newbie with google pixel
Note: i post my isssue to topic https://forum.xda-developers.com/pixel-3-xl/how-to/share-pictures-pixel-3-xl-t3854033/page12, but i think it would be better if i make new seperatelly topic

Yes, nightsight would be better than in daylight but if so why do we need HDR function ?
hi all,
i have another picture with my yard
that when i tap focus on the sky to keep the detail of the building and the sky, the yard is more darker, i dont see any advantage when using HDR function on this camera ?

Photo selfie. Background always unfocused

Today I realized about the bad selfies on a cloudy day. I've not tested in a sunny day yet.
The issue is in the selfie, the background is always a bit unfocused. And I'm not using any TOF option.
I'm in the mountains, and I want mountains focused in a selfie photo. That is impossible.
The worst thing is a selfie with the colleagues, if they are 2 meters behind me, they never are focused.
Quite disappointed.
Any of you is having the same issue?
First disable the AI option, the one on the upper part of the screen, in the middle. Then choose Photo on the lower part of the screen, NOT Portrait. I hope that will help you.

Hi,
I did it, but same result.. would like to know if you are having the same.
Regards
When Portrait mode is activated it is as you describe it. Also you can try manual focusing, just touch over any object behind you.

I will try. But my approach is due to focal distance for the f2.
Thanks

P30 series don't have auto focus on its front camera, only fixed focus, therefore you won't get sharp photos of your background

Hi, Thank you very much. I think that is the key, is a fixed focus.
I will have to use rear camera for the selfies I want to have.

Yes, it was answered from Huawei's president itself during an interview wherein he was also asked why 5g was not implemented on P30 series.
If I understand correctly, focus can't be at same place on the subject and also on the background.
The focus is at some distance, and autofocus feature only configure this distance.

Getting DOT while taking photos during night time

That I am facing the issue of a blue dot appearing in both rear and front camera of POCO X2when shooting against the light in low-light. For example shooting a bulb etc. It is pops up even in daylight when the photo is taken against sunlight, but in day it yellow. Is it a defect? Tell me at the earliest so that I raise a replacement request. Official statement would be much welcomed.

Nothing to worry its just lens glare, it can be observed in every camara just that in poco x2 its more noticeable

Question S22 ultra not switching to 10x tele lens until zoomed till 14x

I have two snapdragon s22 ultra one purchased last week another a month ago
Whenever I reach 10x zoom slider (either directly or even by sliding, from any lens) it switches to 10x lens for a split second and then switches back to 3x lens and zooms digitally.
This happens irrespective of lighting conditions and distance of subject.
Comparing both my s22 ultras side by side I was able to confirm that this problem exists only in one of the phone and not in the other model that phone keeps 10x optical zoom and does not switching to 3x zoom.
Options
A. Any solution to this problem would be highly appreciated?
B. Want to keep formatting as last option.
C. The phone is just 7 days old shall i take it to service centre.
One possible clue, I can make that happen on my S22U in situations where the 3X lens can focus, but the 10X lens can't, for example something about 6 inches away. Then the switchover is delayed as you zoom until about 14x. I'm not sure if it is using the laser ranging for that situation or not, but possibly if the laser thinks you are close, for example taking a picture through glass on a window, it might not switch to the 10x lens until 14x.
But as I said I have another unit at my home.. thuis one constantly switch only after 15 x and not 10x. The other unit is doing perfectly fine for same subject

Return it. I had a similar problem with a Verizon 10+5g with the wide angle lens. Frequent camera error messages turned into always camera error message when selecting wide angle. Sometimes a tap on the corner to a hard surface would fix it but that stopped as a solution after a few times.
I would say if possible, return or change it. My first one was no issue with camera but heating issue.. replaced one; Most of the time randomly pick the regular lens instead of 10x lens. Also at 10x zoom color suddenly changes to fuzzy and dull.
Replaced. This one no color issue but 10x n 30x n 100x has focus issue. Cant focus correctly, output image is most of the time blurry which my first ome had no issue. But i decided to keep as i dont have that time to go n chamge again. I also don't keep phone too long, and i rarely take pic.

How can we know which lens is being used by the phone at 10x? I want to confirm if my unit is not faulty.

After taking the picture check in the picture details the focal length:
10x lens has 27,2 mm
3x lens has 7,9 mm
1x lens has 6,4 mm
0,6x lens has 2,2 mm
You can also just put your finger in front of the lenses to see which one it is using.
I have the same problem here
Any way to solve it?
I've seen this happen in low light. The Periscope 10x zoom is f/4.9, while the 3x zoom is f/2.4. I don't know what the optics of the periscope are, but with the extra reflections/prisms the "t-stop" is probable closer to 5.6 for the periscope lens. That means that the 10x lens gathers approximately 4 times less light, and sometimes the phone seems to stick with cropping the brighter 3x lens in low light because there just isn't enough light. Sometimes in really low light it seems to use the main lens as well.

Sure, but it's strange, because my dad's s22 ultra does not do this, only mine, in same condition. Thinking about changing phone, its my 3 galaxy with problem
Do you think have any way to solve it?
use the expertraw

There is definitely some weird logic that dictates which lens it will use regardless of the zoom level that you request. Is there enough light, can I focus, is the subject too close for the 10x lens or are they shooting through glass and the laser misreads the distance as really close; if one of those things is true it switches lenses.. It happens when you try to take a macro shot too, you can't really control which lens it is going to use and a lot of times you get a crop view that is lower quality from one of the main lenses instead of what you wanted. I've played around with it a lot, and I'm still not sure exactly what it is doing. For example, start out with the 10x zoom about 10 feet from something, then move closer and closer. At some point you will see a little jump in the image as it switches to one of the other lenses without telling you. Then back away slowly, and it does not appear to switch back, keeping the crop from the other lens; I don't know when it switches back. Still, it should not happen all the time, especially with good light and a good subject that is far enough away for the 10x, it COULD be a hardware problem with your device but you also could be falling victim to the complex logic they are using.
Hi All. Similar problem. I was taking close ups of flowers using the PHOTO mode... I had blotchy results at 10x. I did some investigations. It turned out that when using the PRO mode, all was well. I first thought that it was some weird image processing that Samsung did, but that's not true. The truth is that the phone used the 3x camera at 10x magnification on the PHOTO mode! I then discovered that it only switched to the telephoto lens at precisely 15x magnification. Very weird. I can get very good results at 15x. But, when using PRO, the switch occurs at 10x. Samsung - what is going on? It looks like purely a software issue? Paul
Update: I've just restarted the phone. All back to normal and as intended. Lenses switch at precisely 10x.
Update 2: No, this is not due to a restart. The same issue again. The switch sometimes takes place at 10x, but if the phone is to close to the object, the switch will take place at precisely 15x. Super weird and inconsistent.
Update 3: Ok, so the switch between the lenses (on the PHOTO mode) is dictated by the distance between the object and the camera. If the phone is too close to the object, the phone will want to use the 3x lens. Absolutely no issue for long distance shots. These switch at 10x. You have to be super carful with telephoto closeups as you can basically ruin the shot thinking that you are on the 10x lens but in fact you are on the 3x lens. The PRO mode does not have that issue, but then changing iso and shutter speed are a bit hit and miss as well.
Worst still, this is also happening on the VIDEO mode.
For me the middle lens out of three is used for 1&3 zoom and small lens under flash is used for 10x in standard mode. At least kind of, seems to switch depending on distance and also the lower of the three is used for 10x sometimes......
When in pro or expert raw it behave less erratic and uses the lens I choose.
Highly annoying tbh.
I recently discovered this issue and its really embarrassing. Not many of us will go into pro mode and fiddle but as a simple point and shoot. This is terrible.
I am on the latest Software AVF7. My 10x photos keep looking like trash and there is a lot of light around. But i discovered that if you open a picture within the gallery while at 10x zoom and return to the view finder, it switches to the optical and stays. Has to be a bug rather than a defect.
It doesn't seem to be an app bug. I am also on AVF7 and cannot replicate the fault. If it is an app bug, then resetting the camera, clearing the camera app's cache and data should clear it up.
How to verify if this problem is also on my default samsung camera? As far as I'm using my phone, I saw nothing wrong with those zoom lens, but just want to check to make sure.
