Camera Problem: autofocus reacts only after longer rest - Galaxy Note 4 Q&A, Help & Troubleshooting

Got a new Note 4 SM-N910C after I replaced my old, as it had display issues (same model). Old and new phone are running 5.0.1., both are rooted. I restored all apps and data from the old phone on the new via Titanium-Backup.
When I open the carema app, or ANY other camera app on the new phone, it won't focus for approximateli 10-15 seconds - afterwards autofocus works snappy and accurately. When I close the camera app and reopen it, sometimes the autofocus reacts immediately, sometimes I have to wait again. After a longer period in which i did not use the camera, the initial lag always occurs.
Same issue when I use the test mode (#0# - Mega cam). In compairison the old model always works perfectly!
Resetting the camera app does not fix the issue. "Shaking" the phone does not fix the issue.
Does anyone know that issue, does anyone hab a suggestion how to solve the problem. I don't know whether this is a hardware (stuck af-motor??) or a software problem.
I thank you for every answer and suggestion in advance.

Are you on the stock ROM now?

Yes, everythin is stock.. just rooted via CF autoroot..

Did you have this problem before you rooted the device?

It's a hardware problem, the camera lens abit loose. Some tried shaking it but only a temporary fix. Bring it to Samsung Service Centre for repair (if still have warranty). Mine had that problem and was fixed by Samsung.

Update:
I restored the device's factory settings, i.e. Recovery - Full Wipe, and flashed the Lollipop 5.0.1. stock rom via Odin. I did not not restore the camera app usting Titanium Backup.
The error still exists. Shaking the device causes no improvement at all and there are no strange noises during focusing detectable. I suspect that it is therefore definitely not a hardware failure.
.. Once again the error description:
If I do not use the camera for some minutes and open any camera app (e.g. native app, instagram, PS-express, whatsapp, Google Kamera, camera pro and also in the test mode (# 0 # - Mega Cam)) the picture is totally blurry and the focus seems to stay in the macro focus. When I try to set the focus point by touching the screen, the focus indicator appears but the focus does not change for approximately 10 seconds (again, in all camera modes and camera apps). After this "initial lag" the camera works perfectly fine. When I close my camera and open it after a short time, it focuses immediately. When I close my camera and open it after a longer time, initial lag occurs again.
This is extremely annoying.
I suspect that the system deactivates the camera ("deep sleep") so when opening the camera a full "initialization" (i.e. error checking, etc.??) is done every time. According to the Application Manager however, the camera app is active and uses the system's Ram when the lag occurs!
Can anyone - under 5.0.1. - confirm this behavior?
Again, I am very grateful for any kind of help and suggestions!

How difficult is replacing the camera? Is it simple?

Galaxy S camera problems

Just as the thread title says, my camera is full of bugs, unable to change iso/exposure properly and hangs when I try to focus or take a picture. Had the same problem when using jf4 and jm2 as well as third party camera apps. Is this a software or hardware problem? And any solutions?
you are the very first person to complain about this.
just about every body else loves the camera, including me

I had problems testing the panorama shot, but I never complained, mostly because I don't take pictures and I was just testing it. Also, in the camera's defense, I was talking pictures in a room, where perhaps there was an issue due to corners while the shot is intended to be of landscape....any thoughts?
Not exactly complaining but I think that it could be a hardware problem as half of the time I press the camera app, the app starts shows a black screen and says 'camera failed' and force closes...

Is this lag ?
Not much lag, but like I said its real buggy, can't even focus.when I tap on an area the box shifts to wheretapped but it does not focus, the box will now get stuck there and the iso/exposure will not change then usually the camera will stop working

now, that is an actual problem.
did you try rebooting the phone?
if you can't take even a normal picture, you might have an defective camera
Taking a picture is a hit and miss affair, takes pics 2 out of 10 times i try, it should be a camera problem, going to send it in for warranty now. will report back when its fixed
Have you tried a hard reset to see if the problem goes away?
Whenever things start to go wierd, I alway 1)Soft reset 2)If it does not work do a hard reset 3)If still doesn't work, find out if everyone else with the same firmware has the problem 4) Finally, go to the shop for a replacement, it's likely then to be a hardware issue.
If you have 'fring' installed uninstall it and camera will stop failing
Just updated to JM2, I have fring installed, never had such problem even with stock...
Sorry my bad, fring was recently fixed for sgs
Sent from my GT-I9000 using XDA App
Soft reset, hard reset, flashed firmware again. All did not work. Was sent in for repair a few hours ago, they said it would take 2-3 days, had jm2 on it though and where I live the latest firmware is jf4. Hope they don't bother about that. Hoping for the best
Update!
Just got phone back from Samsung after waiting for 4 torturous days, everything seems to be in working order now, the auto focus is still pretty slow though but other than that its great.
So after all it should have just been a hardware problem as the customer service lady told me that they changed the pcb of the camera

HELP PLEASE.... I bought a new Galaxy S Captivate about 3 weeks ago and i think alrealy had the new Android 2.1 with the GPS Fixed. The Camera was working until a few days ago. Every time I start the Camera app, after just 2 or 3 seconds I am getting the Warning message "Camera Failed". I can only press okay and the Camera app closes. I tried many times and it is always the same.
I tried soft reset, and hard reset which errased all my data, and nothing. Today I decided to upgrade to the new Leaked version of the Froyo 2.2 to see if it would help. Nothing helped. I AM STUCK....
I called Samsung 3rd level support and they said that I should send my phone to them for them to REFLASH my phone. If that would not fix they would replace and send another phone to me.
My problem is that I am out of the USA (I am in Brazil now) for the next 3 months, so I would like to find a way to fi via software now.
Since Samsung said that the best way to fix this Camera problem is the FLASH the phone, and only SAMSUNG has this special flashing software, my question is:
1- DOES ANY ONE KNOWS WHER I COULD DOWNLOAD THIS SAMSUNG FLASHING SOFTWARE ? ANY WHAT WHERE I COULD GET THE ROM ORIGINAL CAPTIVATE 2.1 VERSION?
2- I only know this 2 ways to flash or upgrade my phone,
I897UCJF6-final-OCD-REV0.rar (for Android 2.1)
I897UCJI6-OCD-REV02-Low-designgears.exe (for Android 2.2 leaked version)
But I am not sure that this is the SAMSUNG FLASH version that they are talking about , is it?
Where can I find the real Samsung Flash software ? PLEASE HELP
Solved Thanks to Voodoo
Had practically the same problem, Camera failed yet it worked for Video and even in Panorama mode, I didn't install anything new other than some themes from the Market, I tried factory set, removing the battery ... nothing worked, so I disabled OCLF, uninstalled it, and installed Voodoo lag fix instead, that made the trick !! Don't understand why though , but anyways it's working now

[Q] Camera Making Cracking Noise while focussing

I updated my Nexus 4 to Kitkat recently and now I am facing problem while taking pictures.
As soon as an image is captured the camera makes a cracking noise from the backside. Sound is like some switch going on and off "tik tik tik tik"
and then if I minimize the camera app phone can used and camera app can be closed and reopened again.
But if I keep it cracking then within 2 secs the phone freezes and restarts itself.
I tried using other apps like Cymera and I am able to take pictures without any problem.
This problem occurs 50% of the times I use stock camera app. Sometime works fine sometimes hangs up.
How do I get rid of this?
Google support suggested factory reset. I have not rooted my phone. Is there any way I can backup few important apps with their data on PC before I try factory reset?
Thanks in advance!!

I think its caused by camera's focus mechanism and it is just a little click noise but yes sometimes it makes very audible noise, especially with HDR function(which does not focus when you press to focus it just seems green. It only focuses when you move phone or it is just me). Can you check and listen closely if other camera apps doing that click noise when you focus ? I dont think factory reset solve this because I do several factory resets and flashing 4.4 it does not change a thing.
I get that ticking sound as well but only sometimes when I open or close anything that uses the camera, never during focusing. I can't imagine factory reset would help but if you're gonna give it a shot I'd recommend Helium to backup apps https://play.google.com/store/apps/details?id=com.koushikdutta.backup though I think you'd need root to backup any system app data.
Problem Solved
Thanks Scrye & AlderCass,
I did factory reset and tried camera it was working fine. Then google started installing my apps and after that was complete I started getting the problem again. So I got skeptical about some app making the stock camera malfunction. I removed an app called cymera and rebooted the phone.
and to my relief it started behaving awesome like before
Feeling happy

Camera auto focus issue

Whenever i open my camera app, the displayed image will not auto focus- it remains blurry no matter how long i allow it to readjust. The only way i can get it to focus is by shaking the phone vigorously- then it instantly auto focuses. Anyone else experience this or other problems focusing?
Has this always happened? Did you just get the phone?
Sent from my SM-N910U
i got it about 2 weeks ago, and i'm not sure if its always been this way- i never messed with the camera until after i rooted & flashed a new rom. But i do notice the problem on 2 separate note 4's, so i'm wondering if this is a rom specific issue or something others have noticed as well
Try using a third party camera app and see if it makes a difference.
Sent from my SM-N910U
Same thing is happening with my wife's Note 4 camera. Tried DL'ing 3rd party apps, and that didn't work. Shaking it vigorously for about a minute did work, but who wants to do that every time you need to take a pic, especially since we have a 1 yr old. Anyone have any luck with settings? I don't want to have to go back and return the phone, if i can help it.
Glad I'm not alone with focusing problems...
Here is my topic : Note 4 camera won't lock focus + blurry edges on pictures with far focus
Best regards,
Chris.
Problem with initial autofocus
I have the same issue with autofocus. When I open my camera is out of focus. When I a shake the camera it goes into autofocus. This has happen every time so far. I just purchased my a note from an ATT store on Dec 19th. I read on another forum a user sent his back to be fixed. They said it was a software update issue. My question is will it be released to every one soon?
Same issue here. 1 week old note 4.
been using my phone for a month and this blurry back camera is happening lately !!! it was ok when I bought it !! really annoying
Wipe off your camera before opening the app. I'm serious. The rear camera has to be clean or it will try to focus on whatever is on the screen in "close up" mode. It even tries to focus in on fingerprints! I'm dead serious. This was bothering me for almost a whole month before I figured it out.
A lot of you may have already messed with settings, etc. So, reset your camera settings to default, close your camera app (completely by clearing it in recently used apps) and then clean your lens and launch the camera app.
Felt like an idiot after struggling with this so long. Now I just know I have to wipe the lens off before launching the app every time.

This does not fix the issue we are experiencing.
Unfortunately, it's a hardware issue and you need a replacement. You can tap the phone on your hand and it will focus correctly for awhile but it needs to be replaced.
Note 4 af issue
Besides shaking, i noticed it needs sufficient light for it to be calibrated properly. And of course this is only temporary. Not sure if there is a fix for this problem. Bummer
i had issue with kitkat but only for a object in movement. It does not focus object. i compared camera with a Xperia Z1 and it seems to be better than note 4.
I've got the same problem when shooting in macro , the problem is gone when i've updated on lollipop.

You have right. I am waiting for new note 4 from Samsung.
Yes ur right. But this problem started after upgrading to lollipop
Hi, I also have this issue. In the past I never got this issue. I am not sure if this happen after upgrade to Lollipop or not.
But I believe it is not hardware problem as it not happen all the time.
I open camera app and it cannot focus for a while, then I exit from camera, and re-open it again immediately, it can focus.
If I lock and left the phone for a while, let say 5 minutes, and open camera again, the issue come back again.
Is this because software issue like the camera app need to prepare something in background before ready to focus (causing lag before focus) and when we put it to sleep( lock the phone and left for a while) then we open it again and it need to prepare again.
My work around is, if I face camera focus lag, I immediately exit camera app (pressing home or back button ) and re-open camera again and it no lag on focus!
Hope this help you.

Stock camera app not working

Hello everyone! I'm facing a few problems with the stock camera app:
- It closes before 3~5s without throwing any errors
- auto brightness fails to balance the brightness (full light or no light at all)
- portrait mode freezes the app
I already tried to perform a factory reset many times with no success.
I'm living with this problem since first android 9 release. Right now I'm completely annoyed by this.
Is there any way to reinstall the whole system or any other way to fix this issue? I must say that the camera works fine with other apps like instagram, WhatsApp video calls and skype... Looks like something related only with the stock app.

What rom do you have? Factory reset does reset the whole system. You can try to use unbrick tools to flash every partition new but this will be the same.

What’s the main issue causing camera not working?

Everything works fine on this phone until few days ago. When I open the camera, the app responses which means it still response to mode changing and focusing but the viewer black out. I usually use the stock camera but I did test on other applications that uses camera, it just not working and pop a message to tell me reboot. The camera can work after reboot, but never know when will it fail again.
Hope someone knowing the main issue causing the camera not working.
I'm having the same issue, but it's only the rear camera. After I restart the phone it functions without any error. But after some time same issue occurs. Does anyone knows a solution.
