Hello XDA,
I have a problem with my video recording on my Lumia 920 and I believe it is caused by the floating lens. While recording, if I tilt the phone up and down at a resonably low speed, I get a strange shaking effect and the device records a sound too. I will post a video recorded on the 920 to show you what I mean.

Do you think I can fix this myself?? I don't really want to return the device.

"this video is private"
And no, if you are having a hardware problem, it's going to need to be fixed by nokia.
The video is now public. Sorry for that.
Sounds to me like it is the lens settling in your camera after a quick shift in movement. The springs trying to steady the camera will cause that blurring effect. As to how you would fix that, I'm not sure. I havent noticed anything like that in my phone, but I have yet to try that test with my phone personally.
Disable continuous focus and you should be fine.
I've tested mine and it doesn't do this at all. I'm pretty sure you have a hardware fault so you'll need to get it replaced.

Hi,
I recently got the Samsung Galaxy SII and noticed that I'm not getting a clear image from the front facing camera (I'm seeing a bunch of vertical lines). Outdoors the camera is fine, I noticed it occurs indoors (so I'm assuming it's because of low light, although my rooms seem lighted enough) and is more noticeable with a higher screen brightness on the phone and when recording a video. It got me worried enough when I was testing video recording in my room and I was seeing these lines on my face.
I tried searching for answers but couldn't find any, maybe it's because I'm not familiar with camera terminology . Is this what you call a grainy image?
Is this normal? I wasn't expecting quality from the front facing camera anyway, so if other users experience this too then this really isn't much of a problem. The image I uploaded shows the vertical lines I'm talking about. I bumped up the exposure value to get the lines to show more because it looks that bad, sometimes worse, when recording video.
Hopefully this is normal and I'm just being a noob. I don't want any problems on such a great phone! Thank you for any help in advance!
That just looks like noise due to the small sensor, you can try setting the ISO to be locked at 100 to minimise noise. The downside is that shutter speed will be used to compensate so you need to hold the camera steadily.
The phone doesn't let me change the iso for the front facing camera and I can see those lines even before taking the photo or video. I'm just wondering if other users experience this. If not then maybe I need to get it exchanged D:
Thank you for your reply though.
I've ordered the g5 but now I've seen from quite a few videos that the camera stutters really badly while recording, could anyone tell me if there is a fix for this/ whether theres also does. You can see from this link it is especially bad with the wide angle camera.

I can confirm i have the same problem. Sometimes the recordings are nearly free of stutter and sometimes the recordings are like the one from youtube.
I've not yet found a satisfactory solution.
Greetings from Moldova, comrades.
There's an issue bothering me for a couple of months so far... I have an Redmi 4X with very high and good quality cameras, both - front and rear. I get awesome pictures and a very stable video record... but when it comes to Viber, Google Duo and Whatsapp.... the camera they use ( the chromatics ) offer a very poor quality, with a very low bitrate and FPS... lagging and so on.
Could you please explain to me what codecs/ drivers / files do these apps use in order to manipulate the camera? Is there a way to give them the same quality I get with the stock camera? The image is very blurred and laggy....just excatly like the viewfinder of the Photo-Stock-Camera.
please advice me where to put an eye on and where to start digging in order to higher the quality of the video calls for these sensors?
As a tip:
The quality of the image during the viewfinder is opened is exactly the same as the video call using any of the messenger apps. But if I turn of the Noise Reduction in the settings of the Stock Camera, the viewfinder gives a very brilliant clear image. The second problem is the low fps of the viewfinder during low light, but it reffers only to the photo camera. When I switch to the video camera, even the viewfinder has a high FPS.
A guy from the russian forum told me that video/photo viewfinders use different chromatics. What does this mean? How to make them identic?
Why isn't anybody touching this subject? Is this a mistery or a fact that is kept in secret? I am trying to ask this thing for 2 months already and each time the forum users keep ignoring this or telling me I am using the wrong thread or stuff like this.
My question is simple! What is the way an app connects to the sensor and what driver it uses? Why the quality differs from the global camera?

I think you're a little bit pissed off ?.Take some time to relax .
The bad quality during video calls is caused by a poor internet connection.
If you were talking about the video quality when you aren't calling , I can't do anything for you .
Have a good day ( or night )

The bad quality in the same room with another phone with good quality means the phone is related to the problem. First of all Noise reduction isn't turned off like to the stock camera app secondly the bitrate is very low comapring to a Samsung phone with lower CPU and RAM . And it's not the camera sensor that is cheap ( it shoots perfect video and photos even in LOW light ( especially with the API2 camera ON ) I am thankful someone answered lol will still be hoping someone knows how to modify the setting of the camera for a video app. There is something in Android that tells these apps how to use the camera

There is more than this. I am sure there are developers here who understand what I mean, but I guess it is more a policy of the brands. Camera quality is lowered in the code of the ROMs. I am just asking how.
No problem, I will wait until a "good''guy will decide to be open.
I mean, I do hope it’s just me...but I see something really weird in almost any 4K video recorded with Mate 20 Pro....or at least with the one where there’s a sort of rapid panning: it seems like there’s a “stripe” of video at the panning direction edge whenever there’s a rapid “panning” movement where the image is like deformed?!?!
I guess is something dealing with EIS or AI stabilisation, but I’m not sure. What I don’t understand is why no one talks about it. I mean, every review say the mate 20 Pro 4K video are finally stabilised but at what expense? I find those video to be terrible with the “deforming edge”....is it just me?!?!
Here you are an example of what I’m talking about
https://youtu.be/vKS1U56uj04
https://youtu.be/lGUiLgUv-CI (especially from minute 1.03 up to minute 3:00)
I do hope someone having the phone can eventually confirm what I saw.
Thanks in advance

Give it some time... Its still on pre release software, i am sure they are already aware of this,
It happens the same to me, Huawei told me that they are working on it, so you don't have to be worried about that, it's just like AI Vídeo modes ( they just doesn't appear in this pre release version), I'm afraid that we have to wait a couple of weeks more... I have to learn how to be patient! LOL

Ok, then they are aware of this issue. I do hope they really fix it.
Thank you
I have seen the distorted effect on numerous video but this one doesn't seem to have it... perhaps fixed?

Look again. There are still stammers. Pay attention to the cars and see how the traffic is not smooth at all.
If they do not fix it, then shame on huawei and its flagship device.
Thats why im waiting before gettinng this device
It is likely because of stabilization.... try without stabilization...
When stabilizing video the camera only takes a smaller crop from the sensor and uses the information from the edges and gyro sensor data to calculate your movement then it can use that edge informatrion to smoothen out your video.
link to explanation
Due to the physical sensor being 4:3 format and the video being recorded in 16:9 there is still enough edge to work with top and bottom.
Left and right though the sensor has to be cropped, if they chose to crop only little than the stabilization algorithm does not have enough edge information to smooth out the movements and this jitter effect becomes visible.
That of course is only my explananation, i could be wrong

Why is that must be an problem? Why has the iPhone this problem not? So it could be without it.

Because Huawei messed up, that's why they wanna fix it.
Hello,
I recently got a new Mate 10 Pro. I tested the camera and I think that the photos looks ok, but the video quality is not as good. The videos in 4K look ok, but in 1080p/30fps and 1080p/60fps the videos looks bad, noisy.
I updated the phone to Android 9 and EMUI 9 before I shoot the photos and the videos, so I don't know the quality before the update.
Another problem is that I cannot find the video stabilization ON/OFF setting. At one moment I found it, but I don't know if it was before or after the Android 9 update.
I also saw that sometimes the autofocus is not properly working when shooting videos.
My software version is 9.0.0.161.
1. Are there any problems regarding the update or my phone is broken ?
2. Does anyone also have those problems ?
Hi, I don't think you have a hardware problem. I have this phone since 16th november of 2018, with Oreo 8.0.0.157 C432-L29, i didn't have those problems. In Android Pie i think the app doesn't have the same performance like Oreo's. The AI of this app is INCAPABLE of making things right now, for me. Shooting photos is better, but videos in 1080p looks a bit weird , especially in low light condition. Maybe this is the problem. Let's hope in the next updates, they will fix it and make it better.
Thanks for the reply.
Is there anyone more with the same problem ?

1st: video has been very bad on Huawei phones for a long time. It has not gotten better, even the mate 20 pro is far behind apple and Samsung.
2nd: stabilization only works for up to 1080p30. 1080p60 and 4K do not support stabilization thus you won’t find the setting when shooting it.
3rd: the phone has improved it’s photo quality and camera app in general over the past year I have had the phone since Jan 2018. It got updates every 2 months with new features almost every time. They added handheld night mode, face unlock, 960fps slomow, improved aperture depth detection, improved AI (looks a lot less oversaturated now) it also got gpu turbo and much much more. In the span of a year i Must say huawei impressed me.
4th: it took me some time to get to know the camera. Now my shots are much better (I use raw from pro mode) so it’s mostly about the photographer.

I can't find the video stabilization settings in 1080p30. This setting (stabilization on/off) does not appear in the camera menu.
Is the described problem in the first post a software or a hardware problem ? What should I do ?

It is software since it is electronic stabilization it is software only. I have just checked and I don’t have the option in my phone either but I think it’s on automatically since there is a big crop. This is because they use the outer edges of the image sensor to make up for the movement. You can google how EIS in videos work. You can see much more when using 1080p60 so there is no EIS but when you switch to 1080p30 there is a huge crop.
Edit: I have just tested it. Eis works on 1080p30. I was walking and shaking a lot and with 1080p60 there is a lot of shaking with 30 only very little.
Hardware stabilization is optical stabilization but it does not do much (it is always on btw it is a way how the lense is built) except for removing shaking when taking photos it is especially useful in dark conditions where the shutter speed is reduced to take more light in. It will almost do nothing in videos. You can find out if a phone has optical image stabilization if you gently hit you phone close to the camera with one hand while holding it with your other there should be a little noise like there coins inside the phone.. That is because the lenses move around in order to counter camera movement from shaky hands.

Lol sorry. Well it can’t be hardware if all is well when recording 4K or taking photos. So I guess it just doesn’t live up to your standards. In general many YouTube reviews criticize that 1080p looks more like 720p upscaled. Maybe that’s what you mean also.

Hi,Alfred!
May I know the Android version and camera software version on your Mate during that test?
