[Q] Camer preview flickers

Good day all,
I got my Z1 and updated to 4.4.2. Its a non rooted one. I have issues in camera. The camera preview itself flickers all time, even though pictures taken were clear. I tried clearing cache and data files, factory reseted too; didn't help !!! I Is there any way to overcome this bug?
Thanks!!
Reg,
Raj.

Not sure if this is what you mean, but I also have a lot of noise in the viewfinder/camera etc. (hard to describe exactly but sort of like watching analogue television not quite on the station correctly).. have never seen this on any other smartphone..
My phone is brand new.. seems to really only be a problem indoors/low light etc..
Does everyone have this? coming from an S3 its a bit off putting.

There is no difference in Rooted or Not, this is related to the Update, one of many issues. I think there is no fix, just try different Rom, even stock.

Camera Preview not working
since lollipop my camera preview does not work. I can see the small thumbnail but it will not open

[Q] Colour issue when recording video - re-flash camera firmware?

I am having a problem with my HTC one M7 (Rogers) . I am running Android Revolution HD 84.0 (and I have tried the last couple versions without any change in the problem). When recording video the colour information seems to be horribly skewed relative to the brightness data. The screen shows the video properly, the problem is only visible when playing back the video. Here is a video of the problem, and yes I see the irony in using a broken camera to record a video of another broken camera:
It looks like it is either reading a bunch of garbage data before the colour data, or starting partway through the colour data and reading off into another section of memory (I don't know if it is read top to bottom or bottom to top).
I tried changing ROMs and cycled through the last few versions of ARHD without any change in behaviour. I did a factory reset and there was no change. I am not sure what provoked the problem as I don't frequently review my videos so I don't actually know when it started but it was in the last 2-3 months.
My hope would be that the next step is to re-flash the camera firmware but I haven't any idea how to do that on this phone or where I would obtain camera firmware.
Has anybody run into this before? What should I try next?

After some searching I see 2 other people have had this problem with no solution:

This is a known issue with the HTC Camera App. Not a Rom issue or an problem with your camera.
Recording at 1080x720 works fine. It was something to do with HTC implementing the eye experience on the M7 Camera app. You can replace the camera app with an older one but you will lose the eye experience. Or record at 1080x720

I wish known issues like this were better disclosed - I could have avoided wasting people's time.
You seem to be correct, I have changed to the google camera and it seems to be working properly.

Camera stottering - New rom / kernel a solution?

Hello,
because i bought a new phone i gave my "old" Nexus 6 to my wife. Since a updated to Marshmallow i had problems with the camera. It stuttered while making a video. But i dont often used the camera, so i ignored it. My wife is Snapchat addicted and she can't make good videos with the front camera of the N6....it's like a slide show....the record is not smooth. I searched at the internet and a lot of people have the same problem since Adnroid Marchmallow ....
I flashed her CM 14, because i thought it might be a problem with the stock rom , but the problem remained. So my question is. Because i know i had not the problem at Android Lollipop. Is there anybody who had the same problem and solved it with flashing another rom? Or is it worth to try another kernel? I looked at the "rom forum" and found the "sky dragon 5.0 with a "new" kernel and probably i will try this. So my question is....is it a problem with the rom? is it a problem with the kernel? is it a problem with the hardware? What you expert think its the best way to fix the problem (i tried tips in the internet like diasble geodata at the photos or disable the battery safer for the camera app).
I hope you are able to understand my english. Otherwise i will explain it in other words.
Thank you very much!

Flash a factory image (will wipe the phone 100% but take it back to bone stock). If the camera issue is present on stock rom, stock kernel, with no modifications, then it's a hardware issue.

i have had problems with stuttering camera app before but it was fixed by resetting the phone. not really sure why after installing a new ROM you still facing this issue.
have you tried other camera apps? download a free one from the store and see its the same deal.

My first Nexus 6 had no issues whatsoever. When I had to RMA that one for the massive battery bulge issue, my second Nexus 6 had the camera stuttering issue. It would happen whether I was taking still shots or video. Obviously it was more noticeable on video, but it still made taking stills difficult. I took a video at the time to post on here to see if other people where having the same problem, but actually never got around to posting it...

Anyway, I RMAed that phone for the camera issue but then the third N6 had the same issue. I decided to live with it though since (a) Motorola has a really frustrating return policy/procedure, and (b) since two different devices had it I didn't think there was any guarantee that an RMA would fix the problem.
Fortunately, I've noticed that lately (running Nougat now), the stutter has mostly gone away. I'd say that for still pictures it has gone away entirely. For videos, I think it is gone as long as you use the stock camera app. I've noticed that if you use other apps, like Instagram for example, my video still has issues. In that case though, it's more of a constant refocusing issue than a stutter issue.
So moral of the story is... for me at least, it seems to be ok on Nougat as long as you stick to the stock camera app.

Half side blur photo (Unable to focus)

I am not much interested in camera when i bought Mi A2, it works fine. but recently when i was taking picture, it was half side blur and i was not able to make focus on upper side of camera. i tried all modes but no use. I have Note 6 Pro and it's camera functions and focus properly.
in mi A2 I observed when in MANUAL mode i select Lens as LOW LIGHT, it works (but in manual mode only).
do any one has some solution or give reason to behave camera like this.

Same here

It was a February patch bug and it seems to persist in March patch... Xiaomi.

This is a hardware problem, I also had this, give the phone a guarantee.
P.S. sorry for english(

How so we both have exactly the same problem and mine started with pie?

Looks like this is a hardware issue, I'm having the same problem after 4 months of use.

Same here, I also took it to guarantee and they told me it was a software problem, but when they gave it back to me nothing had changed. Camera still not working

I had ordered it from this website but I had paid the cheapest shipping, I'm from Mexico so it will take a while to arrive to my country.. maybe next month..

I had the same problem and replaced the camera module with a new one, and the problem was fixed... temporarily because 3 months after it started happening again with the new camera, so either I am super unlucky, or it must be some other defect in the phone that tends to breaks the primaey cameras...
At this point I don't think I am going to replace it again. Do you know of any way of recording videos with the low light camera?

I have the same issue. In fact this issue persists in the video mode as well. Its okay for videos of objects nearby but move even a few metres away and it becomes very difficult to focus. I was at this concert and wanted to record the performance but only got a very blurry video with muffled sound. For photos this issue is especially an inconvenience when taking photographs of documents etc where you could very well do without the unnecessary bokeh effect. In MANUAL mode this does reduce a bit, but not to any extent that helps.
I was just told by a friend that installing the Google camera mod might help, but I'm yet to try it out.

I have same problem with upper side blur. Seems that switching to "manual" mode and change "lens" from "regular" to "low light", as said by the original user. It works fine with me. Thanks for the tips ! ........ so it is not the hardware problem, it is a software problem. Changing camera may not work ! Don't know if they are going to release new firmware to solve it or not ?? Any idea how to upgrade the firmware ?

If it is a hardware problem I do not see why it would prevent using the secondary camera, it can be a problem with the lenses (Have you thrown or hit your phone?) and not with the module. There are those who have returned to Oreo and the problem persists.

Question MiUi13 - 5x Camera Stability Problem

Has anyone noticed horrible stabilization for the 5x sensor with the new camera app that comes with the 13 update? Used to be able to turn the digital stabilization on or off (when on it caused some weird jitter, but at least the footage was usable and stable). Now, there is no option and the video shot through it is always extremely unstable even when sitting down holding the phone with both hands while remaining as still as possible to the point of beeing useless. Specially at 15x zoom (sample footage included). Anyone else got this issue?
Also noticed that they added an option for HDR10+ shooting and automatic low light framerate adjustment that is not switchable. Anyone know why?
EDIT - Here is the sample footage:
for some reason I got multiple errors uploading video attachments to this forum...

Firstly, I have non of the issues you have mentioned above. I am on MIUI13 SKAMIXM and the app works flawlessly. The only issue I have is video recording gives me only up to x6
Regarding hdr10+ you can turn it on only on 4k and 8k. Not below that.

Okay now I understand, every zoom I start with gives me multiple zoom options. If I start with X5 I can go up to x6.
Either way, works flawlessly

Ok. You mind uploading a sample video in a reply please? Btw if you switch to 1080p 30fps you get the option to go from .5 all the way to 15x in one slider. If you don't mind try shooting from 1x to 15x.
Edit- I'm on the miui 13 SKAEUXM

A quick sample as requested
I am on SKAMIXM
You can try the app I've extracted in my other post, could help you.

Thank you very much. I've installed your camera app and unfortunately the problem persists... the 5x video footage is basically unsusable. I'm afraid that my optical stabilization for this lens is broken and I'll need to return the phone for service, fortunately it's still covered by warranty... This is a huge bummer since they make you format everything on the phone for security reasons.

Hi Mate,
i'd suggest before sending it off for warranty to install GCAM and try it out one more time.
is your ROM official? or is it the BETA version?
Also, I've learned that controlling camera in general is not limited to camera app, also the software of the device control's most of it and the app is just triggering the software to activate and do the algorithm of image processing. it could not be a hardware. (while I agree with you that most likely it is). but i'd try every possible solution before losing device for a few weeks or months if you are unlucky.

Also, note that seems like EU version of MIUI13 rom seems buggy, a few issues have been mentioned here and there that are not in the global version SKAMIXM.

I use miui13 EU ROM and have no issues at all.

Yes I use the official update as provided with the phone updater. I also have a gcam installed and the problem persists there too (sample provided in this reply). I think I've done all the testing required to conclude that there is actually a problem with the stabilization. I'll have to service it unfortunately . Maybe ask for a battery change since it dropped to about 4500mpa over the last few months with all the fast charging and the extremely fast discharging (cough cough). Thank you for your time, I'm really grateful for the tips.

I think I have this here too (I have the SKAEUXM version). Up to 9.5 it doesn't shake, after that it shakes a lot.
