I noticed some strange phenomenon with my Mate 9 camera - it looks like pictures come out blurry if the phone is tilted upwards / downwards after focus has been locked.
Could someone try to reproduce the problem?
The instructions are as follows:
1. set the camera to pro mode and Manual focus.
2. hold the camera normally in portrait position
3. compose with some distant subject in the middle
4. press on the subject to focus on it
5. press the shutter button to take a picture.
6. tilt the camera upwards/downwards (while keeping the subject in the frame). Do not refocus.
7. press the shutter button to take a picture.
In my case, the picture that I get from step 5 is perfectly sharp, while the picture I get from step 7 is very blurry.
It's important not to refocus after step 6. If I refocus at that point, the picture from step 7 comes out fine.
I noticed this accidentally when I tried to take a vertical panorama and saw that the image gets less and less sharp the more I tilt the camera vertically. Example of such result:

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Some observations:
1. It doesn't matter if I'm holding the camera in portrait or in landscape mode; Tilting it upwards / downwards after focus was locked makes the output blurry.
2. The more I tilt it, the blurrier the output gets.
3. The problem appears only when the camera is tilted vertically. Tilting it horizontally is fine. So normal panoramas come out OK, but vertical panoramas do not.
4. The problem appears in both Color mode and Monochrome mode (when only 1 camera/lens module is in use). So at least I know that the problem is not related to the optical image stabilizer (that only the color camera has) or to alignment between the two cameras.
5. It is not a narrow depth-of-field issue: the subjects I checked are very far away from the camera, and basically everything should be in focus. Furthermore, the distance between the camera and the subject is held pretty much constant and still - in one picture they come out sharp, while in another, after tilting the camera upwards/downwards, they come out blurry.
Help to reproduce the problem and to understand it will be appreciated.
Tilt Shift
Wow, that photo looks almost like a tilt-shift photo! Not what you were wanting, but pretty cool looking.

Hi, I am facing the same problem, do you have a solution? Is this a software bug or am I doing something wrong?
I this is a bug, I dont understand, why I only find your concern via google...
Even on EMUI9 I have still this blurry vertical panorama issue

Seen some samples online. Anyone on here have any opinions on night shots with this phone since flash is absent? Does the "night mode" seem to help make the pictures barable...or perphaps does that do better justice than an LED flash would?
I tried "night mode" in my den yesterday with the tv on and just sunlight coming through the shades, it was worthless. The only thing that showed up on the picture was the tv screen while the rest of the picture was black.
Whats your opinon on the camera over-all. I just wish it had flash!

Yes, I wish it had a flash too. Overall I think the camera takes solid pictures, just has to be enough light. Its still just a cellphone camera, though, so dont get rid of your regular digital camera. But in a pinch it takes usable pics. It's better than the 2MP cam on my old iphone.
From pics that I've seen I think the iphone4 camera is the best out there, it has the largest opening that allows the most light in to the sensor. The Droid X also has a great cam, but I think the Galaxy S phones are just behind that one. So its a top 3 cell cam. This, of course, is just my honest opinion.
thanks
I have the samsung mythic now (touch screen feature phone) that has flash and it sometimes helps sometimes doesn't. Of course it's an LED flash so sometimes it makes the object just a big blob of light.

I think phones with LED Flashes / Xenon flashes are overrated. More often then not they lend to washing out the picture completely with a white shade over everything. Only thing I ever used my fuze flash for is a flashlight.
i think if you had a iphone before(not saying you did) those people might be able to live but people who didnt maybe not so much

What menu do you use to find night mode? I've browsed through all the menus on the camera, and none were titled 'night mode'

The TV might have been too bright, throwing off the light ratios. I would imagine that "night mode" just auto-magically adjusts the exposure based on an average of the light recorded. Try a picture in the same settings without the TV screen in the picture and see if it improves...
Thanks!
Thanks a lot for the pics!! Night mode does seem to do pretty good!
All this time I was under the impression that it does work, I mean when you touch the screen it moves the brackets, turns them green and appears to refocus.
I did a very simple test and it seems it's not doing anything. I placed two objects, one in front of the other at different distances from the camera. The result is wherever you touch the screen, trying to focus on the object in the background, it always focuses on the foreground object.
Is this something you can confirm? Is it something rom related or is it a hardware issue?

Yes, it works. IIRC, you need a ROM that supports it to enable touch to focus.
Here's a pic I took now:
Pretty much just helps what it should focus on than focusing on the item that's in the middle. Since you have such limited control of the camera lens, you obviously won't get much control on the depth of field like what you would see with SLR's
That's great and all but in both of those shots the foreground is in focus, which is what I always get. But say I wanted to focus on the little red car in the background (2nd picture) it could never focus.
Can you take the same picture where that red car is in focus and the bottle (?) is out of focus?

It works when I am focusing on the background and not foreground like what you were asking for. However I dont have time now to search for a picture as an example.

I agree with the OP, I have placed an object about 5cm from the camera and have the background at about half a meter away. Without moving the camera, I cannot refocus on the foreground object and background object.
The above examples seem to prove otherwise but it would be more evident if each shot was taken at the EXACT angle and showing different focus.
For now, touch to focus seems to act has normal focus ...

Yeah... for me it only ever focuses on the object in front...

Can any other members confirm if Touch to Focus is working?
I've currently tested on my ROM (CM9 v3.4).
Yeah for some odd reason, my camera will not even focus..
I'm using my nexus 5 out of the box. 4.4.2, not rooted. Everything is great except the other night I tried to shoot some photos at a dark party. friends were dancing. I snapped couple of photos and result ? all blurry. Tried changing scene mode but no luck.
Any help on that ?
Note: camera is fine when i'm taking stable object photos at night. Problem is night and movement together.
make sure your lens is clean on the back of the phone

a certain principle of photography, it needs light to take photos. dark lighting and movement equal blur. proper lighting and movement equal crisp beautiful photos. you need the right lighting for the right shot, period. thats the problem when these amateur blogs review cameras phones, they arent photographers and dont really know how to use a camera properly.

This the solution is to bring a 1000W Spotlight to the party
Lens is clean no problem with that lol. I realized that the problem is with the camera app itself. It is a bit slow at night photos and i admit that it is perfect on stable objects.
I installed Focal beta on my nexus now it takes perfect night ptohos with moving objects. Snaps fast and also you can open your flash before snapping your photo.

Are you using HDR+ mode? If so, try without it.

HDR+ was off ofcourse still no luck with stock camera app.
Hey xda forums, not sure exactly where else I could post this as this seems like a weird software bug.
The problem is the cameras; they are not working as they should. The main lens apparently does not exist, and the cameras are glitched to the point where only the telephoto lens appears on one side (with it having the ultrawide icon and apparent 0.6x magnification when in reality it is using the telephoto lens zoomed in as normal)

}
By pressing the "flip cameras" button, the flipping mechanism does not work. However, the view is flipped 180° and suddenly the ultrawide lens appears! (Disguised as telephoto lens on the app and apparent 3x zoom when it actually is just the ultrawide lens working normally). I would need to manually adjust the flip camera tool to have the camera flip out to me. Also, when taking a picture the app just crashes, and no picture is taken.
The problem also exists in other applications. Snapchat only uses the wide angle lens. However, pressing the flip cameras button does trigger the flip mechanism; a problem here is that the cameras are 180° (upside down).
When using the flashlight feature from the notifications bar, the flashlight turns on and immediately the camera flips, blinding me with the flashlight facing me lol
Anybody have any suggestions on what to do?
Things i noticed before this happened was an error message "The cameras are being used by another application. Please try later". When this message started appearing, all 3 cameras were viewable in the camera app, but when flipping the camera, the app would crash if i tried to flip with the main lens. This lasted for about a week, then the camera app degraded to what I have just described
Things I have tried are:
- Use an alternative camera, such as GCam (won't open, immediately crashes)
- Safe mode
- Factory reset
- Install TWRP and Magisk, advanced wipe and download the ROM off asus website (The ROM which my phone came with as the cameras were working normally for about a month before this happened)
- Install another version of AsusCamera (internet or make backups of system/priv-apps/AsusCamera onto an SD Card and then install)
None of these seem to work. If anyone could help that would be greatly appreciated. Thank you.

Cant use my cameras
Hello everyone ! i have problems with my camera, first of all when i tried to take pictures , it freeze at blackscreen and error message: other aplication is using camera. After factory reset, same thing. Tried flash my phone , then camera opens and there is only 0.6x camera, on slefie mode it...

And the only response was to contact for repair. Is there any chance by software that this can be fixed?
I've had my Mi 10 Ultra, running the xiaomi.eu ROM, for nearly a year or so. I've found the telephoto camera quality to be very good with still subjects, but introduce any kind of motion to the scene, and it is far worse than the Motorola One Zoom I had before.
Here's an example, a slightly cropped photo from the 5x camera, tracking a moving car:

What exactly is going on here? The panel gaps between the doors as well as at the base of the A-pillar have multiplied! Likewise, there's ghosting right by the door handles! My hypothesis is that the camera takes multiple exposures and then haphazardly merges them into one. This makes the camera absolutely useless at photographing anything moving. Hell, I get better quality using stills from a video with the 5x camera than by taking an actual photograph!
So; is there any way to turn this crap off? The photo above is taken in Pro mode with manual settings, and all AI things are turned off already...
Have you tried using the "Pro" mode to set custom shutter speeds yourself?
I find it usually works well, although sometimes I need to turn HDR off to stop the multi-exposure capture if the object is moving too fast.
The attached photo was taken in Pro mode, no HDR.
I don't believe this is an exposure time issue, as parts of the car are sharp, and anyway these flaws look a lot more akin to what you'd find in a poorly stitched panorama. You can also see the pattern on the road surface looks weird, as if it was clone-brushed or something.

You should try gcam. It becomes a real photo camera... Xiaomi processing is very poor compared to Google's.
I have GCam installed, but rarely use it due to the lack of manual settings. Perhaps I'll give it a try with moving subjects, though. Thanks for the idea.
EDIT: tried it, GCam doesn't produce these exposure fusion artefacts at all.
