What’s the main issue causing camera not working? - HTC U Ultra Questions & Answers

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.

Snapchat camera issue?

Ok...something strange is happening when I use snapchat. I take a picture and than the app closes by itself and the camera refuses to work until I reboot...any other camera app will just gove a can nit connect to camera message until I reboot. Ill reboot and any camera app works (stock/instagram) but as soon as I try snapchat again...it auto closes when I take a picture and suddenly the camera wont connect again.
The strangest part is it was working fine earlier...ive been using snapchat since I got the phone with no issues...so not sure whats up...ive uninstalled and reinstalled...so not really sure what else to do...anyone have any suggestions? Anyone else experience this? Do you think maybe its hardware??? I dont think its hardware cause it works fine until I use snapchat...but idk cant figure this one out
Also, I have done notging new to my phone...no nee apps, no new mods, no new updates...nothing so there really is no reason for this behavior. Ill try odin later but im away from my oc at the moment and just wanted to get other peoples input
Edit: snapchat appears to be working again...still strange that that happened...makes me worried as I dont know if it was the hardware or app failing

Fine for me. No issues no lag
I've had the same issue a couple times. It's really weird. It only happens on the rear camera (the 13MP good camera) and only in certain scenarios. I tried to take a picture of my hammock, it locked up and I had to shut down. I took a picture of the ground, no problems. Hammock again, locked up. Flash on/off, doesn't matter. Weirdest thing.
I think it might be the camera software switching between white balances automatically (no proof to back this up, but since it matters where I point the camera, it has to have something to do with what the camera is seeing and doing in response to the scenery) and SnapChat might not play well with one of the white balances.
I just now took a picture of my driveway from inside my house, no problem. Took a picture of the hammock in the yard, freeze up. There's a lot of green in the hammock shot, I don't know if that has anything to do with it.
Have you guys factory reset. First thing I did when I turned it on
My girlfriend's s4 is doing the same thing she only gets it on the front camera but can make it do it at will she says it when the camera first turns on and is focusing and adjusting the color of you take a pic before it settles down it does what the op said.

i think your hammock is cursed o.o and i have no issues. it works fine on both front and back cameras in snapchat/any other camera app.
sorry to bump an old post but did anyone ever find a solution to this problem, its been happening to me on my gs4 from verizon. It will work then all of a sudden it does the same thing with the camera and just exits the app?
Same deal on my Galaxy s4 that is barely a month old. Everything was working perfectly fine until a couple of days ago when I try to send snaps using the rear camera.
Goes something like this:
- Take photo with rear camera, app crashes
- Screen freezes at the Snapchat 'loading' screen OR nonfunctional camera within the app (whereas everything else works such as receiving incoming snaps)
- Rebooting works from time to time, but the problem is reoccurring
- Tried clearing cache/reinstalling the app, no luck
It's starting to really get on my nerves.
I had the same problem. Snapchat force closes and camera starts to fail. I contacted the snapchat team and reported the problem. I got a reply saying that they are working on it. Maybe you guys should send them an email too and explain the problem you guys are having.
I have the exact same issue. I've not been able to find a work-around.
snapchat freezes on videos that are longer then like 2-3 seconds it seems... then i have to restart again to get the camera back...
Nothing is wrong with your phones. Snapchat is an extremely ****tily programmed app. What do you expect from a terrible iOS port?
I might suggest Wink! as an alternative, but it doesn't support video, but meh.
Yeah I have the same problem. It's fricken ridiculous. When will they fix this?

I think it may have to do with using the CM/non TW camera.. Whenever I used it I experienced this very problem. Since I've gone back to TW, I have not..

AOSP on LG G2 not working well with Snapchat

Hello guys,
I'm not sure if this is a well known problem or if it's just me, but it seems there is a problem with snapchat (the camera) when running AOSP-roms on the LG G2 (D802). I've encountered this problem using both PA and CM.
When using snapchat and pressing the "change camera"-button to use the rear camera, the app freezes and I have to force close it. Then, when I open Snapchat again it shows the error message "Unable to connect to camera". When trying to open the camera application it shows the same error message. A reboot seems to fix the problem, but it doesn't take long before I get the same error message.
Is there any solution to this? I'm a little tired of rebooting my device 20-30 times a day. There is no problem on stock firmware, but I really want to use AOSP
I have the same issue on the VS980 and so far havent found a solution and its driving me nuts. Im not real sure how the app itself works but ive wondered if installing a different camera like the lenovo super camera or something along those lines would make any sort of difference, or if its just the app itself. With some searching i read something about google and snapchat knowing of the issue and that it was suppose to be taken care of in one of the 4.4.x updates but it doesnt seem like it
Having the same problem, snapchat will tell me to reboot but I sometimes I can just open the camera app, let it settle and flip the camera back and forth a few times, and then snapchat will magically work again.. still very annoying as I use snapchat a lot

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,

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.

Camera Problem: autofocus reacts only after longer rest

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?

Camera Error

Hey y'all, I got the G6 yesterday and had a camera related question. This is a brand new device, fully updated, and when I go to open the camera, a message pops up saying "Camera Error: Camera Unavailable." Does anyone know how I can fix this?
This seems like an app error because the camera works well on Facebook and Snapchat.
settings -apps-camera -clear cache and date reboot-try!
If not working.....if not working.?.RMA
I already did that and I get the same error. I find this odd.
I was wrong. Both Snapchat and Facebook switch between the single and dual lense back cameras. They do not switch to the front camera.

I have the same issue with my LG G6. Have you fixed yours?
I got a new one, only way to fix it.
Im having the same issue after a screen replacement. The people who replaced the screen even boight a new front camera and replaced it with no luck. Also, the screenshot button for the bottom bar is conpletely missing which i find very odd.
That error seems to be the camera unpluged
I mean the phone is made of connections between hardware and the camera is not connected , its an hardware problem that is fixed by open the phone and plug jt in

I have the same issue with my phone. I replaced the cameras and it still gets the error; however, it does come on when I use a barcode reader...?
I also have the same issue (lg g6 - android 9)
When i open stock app for camera i get error "Camera unavailable".
But with other camera apps like Gcam or Open Camera, it works fine.
I flashed with new rom, but the error is still there.
Any ideas???
- i flashed with Android 9... not solved
- i flashed with Android 8... not solved
Hardware problem?
in that case why camera works fine with any other application, except stock?
Software problem?
it should have been solved after flashing two original roms (8 & 9).
The only explanation i can think is that there is hardware problem with 1 of the 2 camera. And maybe with the wide one. And maybe that's why it is not working with stock app. Maybe other camera apps don't require both camera's (normal and wide lens) to be working.
