[Q] Camera auto focus - Galaxy S II Q&A, Help & Troubleshooting

Hi
I have a question concerning the auto focus of my camera
The thing is that sometimes, when I'm on a rom, for example cyanogenmod 9, I have some problems. Actually, my camera makes a weird noise and the picture on the phone is very blurry, until that I touche the screen and that the autofocus takes effect.
Can someone help me understand this problem (it doesn't happen on all the roms)
Thanks you for your help.

is it possible you accidentally changed some camera settings or camera mode?
Try going to the camera settings menu (bottom left corner of the camera app), scroll that menu all the way out, and pick "reset". This will reset your camera to factory settings. See if the problem still persists.
Or it could be too dark, and auto mode cannot focus. you need to engage night mode. but first try setting reset above.

My guess would be you've switched the macro function on at some point (either deliberately or accidentally) and then forgotten to switch back to auto-focus (I had the same problem with mine until I realised what it was!).
Go to Settings down in the bottom left of the camera screen, then select 'Focus Mode' and change back to 'Auto focus'.
I didnt turn anything on or off, i flashes the firmware to ke7. but it stopped working before i flashed. also i have reset the cam settings tons of times, nothing seems to work. it goes out of focus right after it starts focusing, and then the red bare thing comes up
It is obviously software issues, because its gets perfectly focussed before it goes blurry again
Hmm is it the macro mode issue that I read about?
Never heard anything like what you are describing, sorry.
Please do update this thread if you figure out the issue.
re-flash or update the camera's firmware
+1 to this problem. It's frustating.
I got the same problem. I just give the phone a tap on the back and it starts working again. Its so weird... i'm thinking my camera autofocus is dodgy/stuck
Try Settings >Applications >Manage Aplications > All > Camera > clear DATA
Or are you sure there is no dust on the Lens????? Trying wiping it clean
If both the above Dont work ... I dont you and you dont know me
bump..
have the same issue...
no focus at all in video mode.
i reset the camera setting a few times, delete all data from the camera app, still no luck.
my cam FW is :
cam fw ver : scef02
phone fw ver : tbec28
please advise as this is getting really frustrating...
many thanks.
Samsung I9100 camera focus problem
Hi,
I have the same issue as described above. Perhaps it occured just as I updated to Android version 2.3.3, not sure but could be.
Anyone found a solution to this problem?
auto focus doesn't work correctly out of the box
Hello,
Just got a brand new GSII from Sprint; awesome!! AutoFocus though is CRAZY and possessed!! it will be in focus then go out of focus... non-stop... did this from day one; Running 2.3.4 does not seem to do this with the still camera.
I'm having the same problem. I tried switching roms, going back to stock, nothing helped. Anyone having a solution? It is a software issue, because 3 days ago mine was working for like 5 min..

I had the same problem but disappeared cleaning the lens from the fingerprints and grease
I finally rooted and the flashed Galnet Miui, but then the quality of photos dropped. So I flashed another ROM, same results. So now i restored backup of my original ROM and it got better, but still nowhere near the quality of pre-root.
So I messed up camera for nothing =/
I have the same problem, with one small difference, i dropped the phone in the toilet. Got it dry, changed the camera and now I have this focus problem. In camera mod, if I touch the screen the camera will focus, but it doesn't focus from the moment I start the Camera app. So since the camera don't auto-focus by itself when I go into video mod the image is all blurry.

[Q] CM 10 Camera Crash Problem (Xperia Mini)

Hi,
I am using CM10 nightlies on my smultron and ever since I use it, I have the same bug in my camera. When I open it, I can take pictures by pressing the shutter, but not by touch focus as very often there is an imminent crash (Gallery has been terminated). This is problematic as the shutter method is not reliable in terms of focussing.
Intersting is that after I restart the camera, I am able to use both the touch focus and the shutter focus. But the moment I wanted to capture is gone by then very often
Anyone else with this problem or even a solution?

Remember to do a backup of your gallery in /system/app.

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.

Is my camera faulty?

When I first got my redmi note 4 the focus ring would always be on the screen constantly hunting for focus. Recently the focus ring disappears (the focusing is working) and only show up when I focus on something close.
Thought it was a bug with miui, moved to AOSPE and the problem is still there.
Is everyone else on the same boat or have I got a buggy phone?
(The problem occurs on standard miui camera and Google camera)
Thanks

critical bug with camera autofocus

Hi guys....
Beside the fact that we lost aux access to third party cameras...
I discovered other issue that is more disturbing...
The issue is happening when you focus on distant scenes (landscapes, city scapes etc, anything more then 30m). You can get the perfect focus only if you let the camera in auto, if u try to manual focus or focus lock, focus is not the same anymore no matter what i do...
So that makes the camera unusable in manual focus or in focus lock modes :/
It's the same for me.
Last version stock camera 3.2.100_64
this is the best and worse device in the same time :/
Good hardware, crappy software
