Info about Macro focus camera & Always on Edge app - Xiaomi Poco X3 NFC Questions & Answers

Hi,
I'm a new buyer of POCO X3.
I read many reviews about this smarthpone but I didn't understand if the camera focus is fixed or not.
If the camera focus is fixed ONLY for MACRO pics or also for "standard" shots.
Can you help me?
Other question, I seen a video where an user installed on app ALWAYS ON EDGE. I know this smarthphone isn't AMOLED but I didn't understand if I can installed it on or not?What do you think about this app.
I had a Huawei P8 and I liked RGB led...now, without this I have to check every time my POCO X3 because I don't know, when the led light is on, if I received a call, a message or something else.
Thanks in advance

1st question: The Primary Rear Camera is not fixed focus, and the dedicated Macro Camera is fixed focus (like most of every phones out there equipped with macro like macro is bad actually)
The macro on the poco has a lot of optical abberation (the blue ligns around the pics or in the edges on a subject), paired with a dying 2MP sensor is nuts!
Better to just use the Primary Camera, just take a closeup shot and crop it up, you'll get better textures and details without sacrificing the megapixels, better than the trash macro cam
2nd Question: yeah it will still work but it would take a lot of battery because LCDs are backlit... It cant control pixel one by one... Idk just try and observe

Thanks for reply but I don't understand if, for example, in a panorama, I can focus a tree or a specific point or not.
Regards

Camera is buggy - Too much Noise ( High ISO - 2000-3000 )

Hello,
So I received my all new HTC U11 3 days back ( in India) officially. HTC u11 has world's best rated camera but I am not quite satisfied with the results.
1.) Rear camera is really struggling to capture the photos in low light. I can clearly see the noise.
2.) Front facing camera has no OIS so pictures are blurry and most of the times I noisy photos.
Find the attachments below :
1.) Front facing camera
2 ) rear facing camera
See the noise and level of quality.
hm.. photo #1 has the plant completely out of focus. photo #2 has the pot in focus. you may wanna make sure that the subject is in focus before snapping.
did you change the camera settings to "Touch autoexposure"? The default mode of the camera is "Center-weighted"

Thank you for replying. Let me make the things clear.
The first photo was taken from the selfie camera where I tried to focus on the plant/pot everywhere but it was not focusing anyhow. No matter what it wasn't focusing.
In low light, I can clearly see the noise in the all corners.
The selfie camera doesn't have auto focus everything is in focus ( as long as it is at least 18 inches away). Play around with the settings for the rear camera. HDR auto, HDR, so far all my photos are excellent focal point and background.

Like I said you are too close using the selfie cam, it is meant too be an arm's long away to have everything in focus.

Sir I am not complaining about the focus and all... See the noise... Can't you see the noise in the picture?
Even zoom your spiderman... You will notice the same noise.

Hi. Can you say more here or is there a link to how we can best make this adjustment? I'm not terribly savvy and appreciate the tips. Thx.

Well, in the camera app, pull down the slider with the = icon, swipe to the right to reveal "Settings" which is on the left, tap on that and "Touch autoexposure" should be the first option.
This option is important if you tend to compose your shots with the subject not in the middle (rule of thirds) so tapping on your subject will adjust the exposure and focus according to your subject.
My low light shots are all at over 3000 ISO which leaves quite a bit of visible noise in the picture.
Not liking the camera in poor lighting just yet. Hopefully they will introduce an ISO limiter, or simply fix this in an upcoming update.
I also have a lot of noise in low light photos (rear camera). Automode just isn´t usable if you want to have nice low light photos. The pictures look like that of phones some years ago. Light sources are also always blown out a lot. I also think that the OIS of the U11 isn´t the best out there. So far I don´t really think that this is the best smartphone camera and I was hoping for a better camera performance. HTC told a german magazine in May that they want to deliver an update for the camera. But I don´t know if they really deliver or if this update was the small update of June (?) of the camera app itself. I did this update and nothing changed.
Camera is phenomenal with stunning low light performance.
Check one of mine in auto

Guys, I've been into photography for over 40yrs. - shooting at ISO 3000 will give you noise onless you're using one of the latest Pro or Prosumer cameras w/advanced sensors- the Nikon D5 / D500 are full frame cropped frame verions ef virtually the same camera in terms of auto focus, pic rendition, & yes, superlative results w/astronomical ISO's - which both support. This is a phone, not a prosumer or petter camera. 3000 ISO is gonna give noise. There are a number of companies that make post processing software specifically to help w/Noise. That nite shot the other fellow took is good work.
The phone is great. The camera is quite good. Deal w/the technical realities & don't expect the cellphone camera to deal w/noise like a Pro DSLR.

That's great, but the ISO fired at only 1262.
Whenever I take a shot in similar lighting, auto mode uses ISO 3152, which means there will be a lot of noise.
Perhaps there are different software versions going around, because my phone has very poor low light performance in auto mode due to it using a far higher ISO than it should.

I'm not expecting such a small sensor to handle ISO well - I'm expecting that the camera won't default to a ridiculously high ISO like 3152 where my previous Samsung S6 was happily snapping along at ~1000 with stellar results.
Yes, everyone knows that this isn't a DSLR. But when they claim to have the best smartphone camera around I expect better results. I also don't know why they use a smaller sensor than before... This phone goes for 749 Euro and the low light results often look like from an old S5 or iPhone 4. The Automode just isn't usable in this scenarios. If they deliver an update they could solve the issues, I guess.
Turn on pro mode and drop ISO..

And here in the first sample you can see what I mean with this weak OIS...
Zico, as someone else said go Pro mode & get lower ISO, & even if this phone's camera sensor is smaller than prev ones, - compared to a Pro(sumer) DSLR, this fone's cam compared to prev one vs.
DSLR is like the choosing pinch hitters who bat .249 & .253- the smaller fone sensor is just a bit less than the prev *slightly* bigger one- then there is the density of pixels & dynamic range that make for a good camera - Y am I still talking abt this?
Pro mode and manually selecting ISO is not a solution to a poorly tuned auto mode - it is a workaround that is barely tolerable.

FAKE dual camera setup on Xiaomi Mi A1? [Not Really]

Greetings my dear Mi A1 brethren! Today I am the bearer of bad news for you guys. From unreleased source codes to headphone hissing. This problem is the final nail in Xiaomi's coffin for me. I will never ever buy another Xiaomi device again.
I have reason to believe that the "dual" camera setup on the Xiaomi is FAKE! Let me show you. Follow these steps:
1) Open up the camera app.
2) Cover ONE of the two camera lenses at the back with your finger.
2) Zoom in to 2x mode (or greater).
Did you notice something? THE CAMERA LENSES DO NOT SWITCH! The main point of the Mi A1's dual camera setup is that one lens is wide angle and the other is telephoto (as mentioned on their website). When you zoom in, the app should automatically switch cameras.
Another test is that the dual camera setup should provide a background blur (bokeh effect) on objects that are up close to the camera. Cover a lens with one of your fingers and you'll see that either the camera gets blocked by the finger or the blur effect still remains (regardless of the fact that TWO cameras are needed for a proper bokeh effect)!
Both these tests prove that one of the Xiaomi Mi A1 cameras is a dummy. Has Xiaomi lied to us again? Why would Google let them do this?
Or is it that I don't understand how dual cameras work? Someone please enlighten me. I feel I've wasted 250$ of my hard earned cash on a scam
EDIT: Nevermind! I just found out it does work. But only in manual mode or portrait mode. Strange that the app does not switch to telephoto mode automatically. Perhaps in a future update.
Have you tried manual mode

Yes, I did. I've edited the OP. I feel like a goof for not trying that first
No its real!
Try that in outdoor lighting conditions.
In natural lighting cover the zoom lens, and then hit the 2x zoom.
You will notice that the zoom lens is functional in good lighting conditions, not in bad light conditions.
Same with the portrait mode, thats why it is recommended to use 2x optical zoom and portrait mode in outdoor lighting conditions.
The camera decides if it should use digital zoom or telephoto lens depending on light conditions. Telephoto zoom only works with a lot of light(like portrait). If there is not enough light, digital zoom from wide angle lens is better. This even happens on iphone 7plus/8plus camera set up(if there is not enough light they just use digital zoom). However, I think that maybe it switches to wide angle digital zoom sometimes in good light conditions.
I can understand that you were concerned but please test things thoroughly before posting (or maybe Google it out). Actually the telephoto camera have a narrower aperture then the main camera. So it captures less light then the primary camera. When who cover the telephoto camera to see if it is working or not, then hit x2, it detects that there is low light (since you are covering the lens) & hence uses the primary camera. Okay, so this is how you should have tested. First go to a very will lit environment, then select 2x zoom, and then try covering the telephone camera. You will get the proper results. Hope this helps.
It's the same in Oneplus 5, for example!
Telephoto works properly only in good light situation

If you want to know before clicking a photo which lens is used for 2x zoom just look at the animation when you use the zoom button. If theirs an animation of zooming then it's digital zoom & if it is directly switching to 2x or 1x then it is actually switching between the lenses. And it won't change with a future update too as the OP hopes. Works the same way even on iPhones. It OK to have questions but you went too far calling it a scam, fake & never buying from Xiaomi again.

Doogee mix 2 - camera

Hi guys,
I appreciate that this is a specific Mix 2 question but couldnt see a mix 2 section yet to post in.
I recieved my Mix 2 about a week ago and my first impressions are that its a great phone - it does everything I want....... apart from when it comes to the cameras.
Firstly, the quality is pretty bad and a large step back from the oppo find 7 I am switching from. Both front and rear facing cameras fail to properly focus and always seem to take photos like there is a dirty lens, a sort of soft look, most obvious when photographing text, which just isnt sharp at all.
Secondly, it appears that the second rear facing camera doesn't do anything - is it even real?!? I believe its there for the optical zoom option, but even when you zoom in with the camera app, you can still cover this camera and it has no effect on the photo, therefore it is not used.
Any ideas on how to improve the picture quality? I presume its going to be a case of waiting for Doogee or some developers to take this device on to update the firmware......
Thanks

A new update of the firmware is being "cooked" to solve this problem.
I know that will be released soon.

It would be great... Camera performance is the main issue of the device. On the other hand, all the other features are quite well
Sorry to put this query here. Even i haven't got any place to right it down. I also have a same problem. Rear camera not working. Bought this phone specially for camera specifications. When will be the updates release to make the second rear camera work. Even 8 MP Nokia camera takes better picture than this 16 MP. And there are many bugs. Many apps crashes. And on YouTube I have seen many videos which shows many camera app showing 4k video recording option, but I think that was after update and I still haven't received it.i show that video 1 month back.
New update from company has improved the camera lil bit. But still not a usable one. And it keeps on hunting for focus in video.
From morning all Google apps are getting closed by itself. Please help to solve the issue in mix 2
no updates have improved the camera on this phone for me so far. Taking photos of static images is ok - maybe 6/10, if I use whatsapp to take a photo of anything it always appears very soft and a little blurred. If I try to take a photo of my cat.....no chance, the shutter is so slow, unless the object doesnt move at all you cant capture the image. I do like the phone and previously havent been bothered about camera specs, but that was when all my previous phones could take decent pictures. This might be the reason I get rid of this phone in a few months, it turns out a decent camera is a must for me - I was spoilt with my Oppo find 7, which had an incredible camera

+1 about camera perfrmance, i bought it to do a review and the camera is the worst thing in an otherwise decent phone. I did a comparison with the honor 7x, which has a much better camera at the same price.

Hallo guys, there isn't a procedure to flash Google camera hdr+ on this smartphone o mediatek CPU. I founded everything for Qualcomm but nothing to mediatek.

Ultra-wide angle camera color science is off?

Apart from the frustrating fact that you can't record video and that the ultra-wide lens isn't very wide, the colors and seem to be extremely off in the comparisons I've seen to the point that I don't know if it's solvable through a software update. Maybe fixing the distortion and the super low saturation through software will somewhat save it, I don't know. Heck, even Mi 9 has a clearly superior ultra-wide WITH recording. What do you think? Does anyone that has the phone have a different experience? I want to buy this phone, but at this point in my country it's about the same price as a S10+ (Exynos) and I'm struggling to make a decision.
I wish GCam mods come early to save this mess.

I cannot answer specifically to the 7 Pro, but I can tell you that the colour science is off on my now-sold Galaxy S10 Plus Exynos version. Switching between the main lens and the wide angle lens in the same exact lighting and spot yields different colour reproduction. It might be down to the actual lens used in junction with the software, but I can safety say that this problem isn't exclusive to the 7 Pro if anything.
Also, don't buy the Exynos version of the S10. It has garbage battery life, and has different camera lenses to the SD version that have shown to be inferior to the SD version.
There is a setting in the camera called "Ultra Wide Lens Correction." I wonder if testers are switching this setting to see if this is the issue. I just got mine, but it's night time right now so I will need some time to test (but I only have the LG G7 ThinQ to compare to.)

Yes, but at least every other wide angle camera in the market gives decent results. 7 Pro's results are very undersaturated, very soft and sometimes seem like out of focus.
I know about the S10+. If it was a Snapdragon version I would have already bought it.

Great! Post some samples when you can. I'm not that worried about the lens correction, I don't mind the distortion. My problem is mainly the saturation and softness of detail. If you can, post original results + "corrected" versions using Snapseed/Photoshop to check if some post-processing saves the day at least. Thank you in advance!

Beauty of OnePlus and this wonderful community is the fact that there'll be GCam for it very soon, and we'll undoubtedly be able to take amazing shots through GCam using the wide angle lens.

It really depends. It might not be fixable with gcam.
The main camera uses a pretty good sensor. But it is a different sensor for the wide angle lens. So the quality of the wide angle shots will heavily depend on the quality of the sensor they use for their wide angle lens. It might be a weak sensor, we don't know right now. Huawei uses 4 Sony sensors for example, their wide angle pictures are pretty good. And yes, the best hardware is useless without a good software. But the best software also can't fix a bad sensor.
Not saying that it is a bad sensor, it's just that we don't know by now. We might have to wait for a teardown and some talented devs to see what is inside and if it is fixable.
I can only link you the specs from dxomark:
Primary: 48Mp Sony IMX586 sensor (12Mp output size), 26mm-equivalent lens with f/1.6 aperture and OIS
Ultra-wide: 16Mp sensor, 17mm-equivalent lens with f/2.2 aperture
Telephoto: 8Mp sensor, 78mm-equivalent lens with f/2.4 aperture and OIS

Question Are the back cameras a sham?

Hey,
I was really wondering if the back cameras are actually helping the picture quality at all.
I have tried using different camera apps and covering some of the lenses and the picture/video quality seems always to be the same even if it's only 1 lense uncovered.
Can someone confirm/deny?
IMHO pretty useless, but you should see difference in portrait mode, where background is blurry when additional modules work and sharp when are covered.
Uhm.... you have 3 Back Cameras.
1 is Normal Mode 48mp or rather 12mp with Quad Bayer raster.
2 is wide Angle which has bigger FoV
3 is Macro Lens.
And only one camera is used at a time.
Only exception is the ToF Sensor that looks like a camera but only brings Depth infos for focus.
IMHO best Camera Quality comes with Google Camera mod and a custom XML.
