camera flicker problem - Vibrant Q&A, Help & Troubleshooting

hi,
when opening the camera app, i see flickering when pointing the camera to white objects(like a wall), and it is usually when i'm in a room.
in sunlight i can't see the problem, and when looking at dark objects it is less noticeable.
i did a test with my friend that has i9000 and we tested in the same room and he doesn't have this problem.
it also happens when shooting videos(i can see the flicker when playing back the file)
my rom is bionix-v.
this problem started before this rom, so i don't know if it's related.
thanks.

strange camera buzzing noise

Hi iv recently noticed when i start the camera app up and lighty tap the back of the phone the camera starts to make a buzzing noise then when i tap again it stops has anyone else had a simlar prooblem... im on 2.3.5 XXKI4 not rooted... cam ver.. ONEF01
I'm having these symptoms sometimes too. The buzzing seems to come from the LED-lamp and by tapping the LED it disappears but not always. If I change the focus point in the picture the buzzing stops.
The problem comes and goes and I haven't done any more research on the issue.
Exactly the same for me, iv found that the problem is worse if the led camera light had been on for a while and usualy i have to flick between video and pic camera then it starts buzzing like crazy. Is now stopped very strange i hope its more software then hardware..
My phone does this "buzzing" too. I'm on SLIM ICS 4.0 now, but it happened when i was on GB too. I think is related to the focus mechanism, as it stops if i refocus while i'm in camera app. It also starts sometimes when i toggle on the torch from the statusbar, but it stops if i gently "hit" the phone in the camera area...
So...it seems and i hope is a software problem...
It's the camera lens vibrating very quickly, if you look at the screen you will see a "motion blur" on the live image until the lens focuses on something and it will stop.
I sent my GS2 back for this and various other issues, Samsung fixed only one problem and sent the phone back without looking at the camera it seems.
Happens on GB and ICS.. Didn't happen until around 9 months of use, from new..
I think this is a fault that Samsung should take seriously..
Sent from my GT-I9100 using xda premium
It´s normal.
I think too its the focus of the lense. Cause it make this when i tap to focus anywhere
It isn't normal for sure. Something like this can't be normal. But we can't do anything so we have to live with it

Screen flickering while recording

Hey guys...
I'm just wondering if i'm the only person having this problem. Before the .15 update, when i recorded and used those stupid effects (make eyes big, face small...etc) it was recording fine. But today i was trying to shoot a video using the effect, and when i played the video it had a screen tear/flicker on the top of my screen. Can anyone check if they're having the same problem?
The screen has a \____/ kinda shape flickering on the top of the screen when i'm playing the videos.
thanks
This is a BUG! I have this problem when i hit a recent apps botton...Please turn on screen and then 20-30second dont touch your screen when is in homepage then go to settings and do you see any homepage widget,icon like ghosting (screen burn)?
Yup
I have the same issue when using the front facing and Rear facing camera w/ video effects. Hopefully it gets fixed soon. Running Virtuous Rom

HELP: Camera acting wierd!

I have an Alcatel One Touch Fierce and recently my back camera has been acting wierd, whenever I take a video if its a bit dark the video itself will get darker. if I'm outside its fine but in dim rooms its like the exposure sets itself to -100 and contrast to dark. If I move it to the window the video gets fixed and normal lighting. This only happens while recording, and when you save the video itself it saves the parts where it gets dark or back to normal when moved somewhere more bright. This started happening a month after I got the phone any ideas??? THANKS IN ADVANCE!

RS988: Is my camera defective (Snapchat)?

Hey all, so I got the unlocked US model of the G5. First thing I noticed is a scratch on the back on the paint near the camera. I was upset, but thinking if I returned it, I'd get something worse back.
Anyways, when I went to use Snapchat, I noticed if everything is on the dark side I can see some lines on the video/photo viewfinder and it stays in photos/videos if it shows while recording. So far this only appears to happen in Snapchat, so I'm hoping it's something with the app, as it doesn't show in the stock camera. (See sample video below)
Can anyone who uses Snapchat check if this is a thing?

Thanks for any input!
I think if you have your phone in any version of English other than US, it will change the anti-banding setting in all camera apps. I can't watch the video right now, but it sounds like what you're describing. Snapchat is working just fine for me.

I don't think that's the problem. I'm in the U.S. and have it set to U.S. (just tried UK, as well).
It comes and goes and only on the right side of the screen.
I noticed also in the stock camera app it seems the viewfinder "lags" (has lots of motion blur) while taking photos., causing some photos to come out blurry. This never happened on my G5 H815.
My snapchat is the same, I get those lines down too
I have a Verizon G5 and have those exact issues in Snapchat. Strange, dully colored vertical lines when moving the rear camera, and a dark front camera.
The front seems to be a bit better from an update, but I'm thinking they have no idea how to code for the dual cameras.
I have the same problem on my g5 rs988
Update your Snapchat app, the issues I use to have is that front camera flashes on snapchat when trying to use it in low light photos or rooms, inside places, etc. Otherways the photo came extremaly grainy too, but no that lines.
Later I joined beta and it seems solved now i dont see that flashes from black to light or grainy selfies, even the resolution looks like normal camera even in low light
Same for me with G5 H850
The snapchat camera is fixed now.

Camera issues on my z7 (NX506J). anyone else have these?

Hey guys. As you can read in the title its about some problems i ran into when using the camera. Using the official v3.88 rom btw
For example
Video recording
4k records in laggy 15 fps in good light, 11 fps low light
1080p records 24 fps in good light, 11 fps in low light
For 720p its the same as 1080p
Photography
I have focusing issues when using automatic mode on macro and/or close up shots. Camera tries to focus, then focuses beyond the sweet spot (meaning its sharp but it still adjust focus beyond that so it gets blurry again), and then it jumps back to what the focus was before. Happens very rarely that it stops the focus where it should be to get a good picture.
Now for low light and complete dark conditions using the led flash.
The focus issues here here are similar to the previous macro/close up issue.
Example scenario: complete dark room, camera with flash led enabled. Now when i try to take a picture using the shutter button (not onscreen one as this just shoots without attempting to focus at all), the led turns on, camera tries to focus, led turns off after focusing, focusing indicator appears again somehow (orange square), now i press the shutter down completely, it takes the picture and it comes out really blurry as it resets the focus right to where it was at the beginning (thats what similar to the macro shots).
Does anyone of u guys have these problem on the same rom (v3.88)?
Do any Mini and Max users here have similar issues?
If u have time pls try out the things mentioned above (video and photography pls) and post your results if you have the same issues or similar things happening to you.
Anyone?
Guys, pls. Already 170 views and nobody answered. This goes to anyone. Max, mini and normal z7 users. Pls tell me about if u have got camera issues or not on the latest available stock rom on your phone
I'm having the same problems with videorecording, low FPS in low light, like 10-20. Im using Resurrection Remix 7.1.1 though, i dont rememeber if this happened with the stock version i had (3.84). Have you found any fix to this?
Edit: i´ve found a workaround for the low FPS in low light. You have to set the "exposure" setting to -2, it will make the video darker but you will get a stable framerate.

Thank you for responding. Yeah i know its due to exposure being too aggressive while video recording. What about taking pictures in low light (or even in a completely dark room) with led flash on? Does it focus correctly and captures a sharp image or does it kinda reset the focus after led turns off and gives u a blurry result?
And what about 4k video recording. Does it give you stable 30 fps in good light conditions? I know mine didnt.
