Is your camera locking up (No pre-view picture)?

Is your camera locking up (No pre-view picture)?
When I select the camera icon, I see the camera menu in the lower part of the screen and I can even take pictures, however I see a black image instead of the pre-view photo on the screen. This issue goes away by soft resetting the phone; however it usually comes back after few days and the only way to see the pre-view image is by resetting the phone. The strange part is that the camera can actually take pictures but I cannot see the photo before taking it. Have you heard of this issue? The phone works just fine otherwise and I like it a lot.
Thanks,

Are you running stock?
I can't speak for whatever potential issues might be caused by any of the custom roms in circulation, but on a stock phone, obviously it shouldn't be doing that.
I can't imagine what hardware issue would produce intermittent preview-ability that's temporarily remedied by a soft reset, yet still manages to capture the photo itself, but there's a first time for everything.

My stock camera application (and Camera360) and camcorder applications both exhibit this behavior. A soft-reset of the device usually temporarily resolves the issue (i.e. allows me to use the camera for a short period of time). However, after my phone has been on for a while any app that uses the camera just locks up (eventually have to force close or soft-reset).
It is rather annoying. The only information I found seems to indicate that there may be an issue with the API within FroYo itself. Hopefully when we get the update to GingerBread the problem will resolve itself.
I also read something else about something to do with an LED widget that caused someone problems but I'm not using any LED widgets, so I'm not sure what that's referring to.
Hopefully there's a fix out there somewhere or we get the 2.3 update soonish.

Hmmm...
This is the first thread I've come across that brings up this problem.
My stock (rooted) phone, my mom's stock phone, and my dad's stock phone have never encountered an issue like this, but then again, maybe we were the three lucky ones...
EDIT:
That's not to say you guys are crazy... maybe we just haven't had the right combo of circumstances to expose the problem/bug on our phones.
Now that I think more about it, I did have an issue when I ran barcode scanner once, about a month ago. That of course uses the camera. As soon as it identified the barcode, and I pressed the 'search web' button, it just froze (image still visible), but the back key/screen input was unresponsive. The only thing that worked was the home button, which, instead of going to the home screen, displayed the screen you see when you are about to end a call with someone on your phone. Thing is, I hadn't made a single call that day. That screen was also unresponsive, but when I pushed the home button again, it finally got to the home screen.
I then went into manage apps in settings and FC'd barcode scanner and the dialer/phone, just in case. I even uninstalled barcode scanner because I thought it might have a phone-specific bug that I didn't want to deal with.
I don't know if there's any correlation between the yours/OP's issue, but it sounds like it's ****ed up in a similar way. FWIW.

I think I managed to fix mine by wiping my dalvik cache. On the downside, my current drain used to be around 5 when my phone was in standby and now it is around 45. On the upside, I haven't had a problem with the camera or camcorder since then.

Mine ended up being a hardware issue. Phone was exchanged with at&t. Haven't had an issue with the camera since.
Just wanted to update for the OP.

G2X Camera Won't Launch

For some reason, the Camera function on my G2X no longer works. It worked a few times previously, but now every time I launch the screen flickers and nothing launches.
Persists across reboot. Cleared data on the camera app, want to avoid wiping the phone if possible.
Anyone run into this, before, or know a fix?

Haven't run into this problem myself but you could try downloading an alternate camera app from the market to see if that works. If it does, you may have to factory reset your phone. If it doesn't, it may be the hardware(the camera itself).

I noticed this problem as well, after rooting the phone. I'm not sure if it was an issue before that or not. But what I found is that if you rotate the phone into landscape mode and then open the camera app it works fine. Only trying to open it in portrait caused me any issues. Hope this helps.

This is ridiculous.
Yet true.
I'll be resetting my phone tonight to fix the battery drain, hopefully this will be resolved at the same time. But this definitely worked, so I can test out this camera some more while I wait. Thanks!

I had this issue too. Try opening while in landscape. Once open switch to portrait then close while in portrait. You should be able to open on portrait after.
Edit: This only works some of the time

Has anyone figured out the camera issue? I had my camera working fine, I rooted the phone and now the camera just flickers around the button. Must have this camera working.
Thanks

Had same issue, as you noted the reset solved my problem, camera is working AOK. I would have hated to loose the camera function, it is a good camera.

2nd phone that my damn camera stopped working after about 15 minutes. I didn't root this phone to make sure that wasn't the issue. The camera worked after I did a factory wipe, got it all set up and was taking pictures while I was setting it up to make sure it wasn't a rogue app. Thought I was in the clear and tried to take a picture and nothing. Same problem everyone else is having. just wiped the phone again for the 3rd time and camera works, going thru same process, can anyone give me any advice on this camera. Very strange and getting real pissed off.

I use anylock to bypass my lock screen so when I get a text message (ssm popup) It will open up my screen automatic and display text message. This way I'm not always pushing my power button to gain entry to phone. Problem is the lock screen app is some how screwing up the camera app. Also tried no lock and same problem.
Just wanted to let anyone using lock screens what I encountered, maybe save you hours of resetting phone.

Mine was doing the same thing and I was about to blame it on Pauls patch. It turned out to be widget locker. I froze it in Titanium and then it came on with no problem. I was really close to wiping AGAIN. Really glad I saw this. Thank You

Camera black screen

I get a black screen in Camera, Camcorder,
I'm using the XTv2MIUI ROM.
Anybody can help to fix it. Have install back to the 2.1 stock rom, format the SD ,deleted the 3rd party cam apps. Still can't fix it.

Wow so even after flashing back to stock you're still getting black screen? I've seen the black screen a few times with miui but not everytime. I was hoping it would be fixed with the final v5.

thats weird. the first time a flashed Miui I had that same problem. I just reflashed the same rom and the problem went away. I have never carried the black screen through multiple roms.

Even I flash back to the stock rom by RSD the black screen can't fixed. I already replaced the camera module but not fixed.

Do you use autokiller memory optimizer? I got black screens when I set it above strict. If you do maybe youd want to lower those settings.

I didn't install the auto killer, But even i flash back to 2.1 stock rom without any tweak apps,it still can't fixed the black screen

Hmm, same issue in several ROMs, sounds like an hardware error.
I have found the following in Loyat Forum:
(http://forum.lowyat.net/topic/1667176)
Help! My camera shutter suddenly closed up and can't open anymore. Is this normal or my phone is screwed?
This is a known issue for xt720. Not all of them though but quite a number have experienced it already where the shutter just completely shut. There's nothing much can be done other than sending it back for warranty... OR you can try this trick. Get a magnet and put its South field close to the shutter. Apparently it will open up. Not sure how true is this but yea.... better than dismantle the whole phone just to find out you really screw the phone up for good...​
Maybe this could help...

[Q] Camera and lamp won't open

Hi everyone, I've look everywhere and I'm kind of desperate now
So, I've had my nexus 5 since it came out here in Europe, never had an unsolvable issue (thanks to the internet), but right now I'm stuck
MY PROBLEM :
One day (just like this, I don't remember doing anything special with my phone), the camera completely stopped working, along with the lamp.
DETAILS ABOUT THE PROBLEM (The situation right now) :
1. Camera doesn't show up in the application drawers
2. It DOES show up in Settings/Applications, and in "My applications" tab from Google Play, but I cannot open it in any way. When I could, however, it would just crash away.
3. I am also unable to access the stock lamp from anywhere (quick settings, etc.)
THE INITIAL SITUATION AND THE EVOLUTION OF THE PROBLEM :
1. I was running CM12.1 (nightlies) on my Nexus 5, and I beieve it occured after an update, but I don't believe it really has much to do with it. When I tried to open the camera, it would show me "unable to get a link with the camera" (translation may not be exact) and the system lamp had disappeared
2. I tried to downgrade the phone, to an earlier nightly, but it didn't fix it.
3. I've donne every kind of wipes : Data, Dalvik, Cache, even Internal Storage
4. After a full Internal Storage Wipe, I reflashed fresh Marshmallow images from the official website, unrooted, reflashed stock recovery, relocked the bootloader and used the system factory reset again on my phone.
5. After this, the problem changed a little bit. The lamp is still impossible to find, but however this time the camera is too. What I mean is, on CM, it used to show up and crash, now I can't find it in the app drawer (See DETAILS ABOUT THE PROBLEM)
I think that's all, so yeah, this one is kind of a challenge.
If the solution is software... Well i really dont know what I could try else; if it's hardware, I'm not afraid to open up my phone. (however I'm a complete noob)
One last thing, I've contacted Google, but the phone they sent me back was in such a bad state that I'm keeping mine (or getting them to send me an other), because the power button was really used, and the lowest part of the screen really "white" (brighter than the rest, my guess was it had fallen)
Thank you very much !

Hi, looks like we have the same problem. Unfortunately I have no solution for you, either. I have ordered a new rear camera from ebay that should show up here end of January. I'll let you know if that fixed the problem.

As you can see from my recent post, I am also having the same problem. I have also order a replacement rear camera from ebay and I fitted it. It worked for one day and then it also stopped working. I am not sure whether it is worth repeating this experiment or I'd just be wasting money on replacement cameras. So annoying, because, apart from the camera (and the torch), the rest of the phone functionalities are still perfectly fine.

Has anyone tried to use a different camera or torch app?

That's odd then. It seems like you've done nearly everything that should of been done. I'm at a loss for words here

ZTE Blade X1 5G Front Camera Freezes after a Period of Time only after phone reset can if be used again.

I've had this phone for about 3 months now with YahooMobile. It seems like a nice enough phone but after a month the Camera Froze. I could clear clear cache and Data cache to bring it back up again, but as soon as I switch it to front camera it froze again. The Rear camera functions fine until I bring up front again and everything has to be cleared out again. If I factory reset the OS, it functions fine for a period of time then starts freezes again. I tried watching my app installs to see if it happened for a particular app but with half the apps installed as the previous times and no new apps running camera permissions it does it again. Is anyone having this problem and found a solution?
I've sent my phone back to zte 3 times now and on the 3rd time they finally sent me a replacement phone. One week into using it, it froze on selfie camera. The first and 3rd time I sent it to them they did testing and factory reset but nothing more, insuring that the problem would return. The second time I sent it to them I factory reset it myself and they did nothing to it but send it back because they couldn't find a problem. They told me not to install "ANY" 3rd party apps on the phone.

I have the blade x1 5g too. It is a great phone except for this issue After about 2 months the screen freezes when the front camera is activated. Long press on camera icon and select photo will get out of it. Factory reset is only thing I have found that allows it to work correctly. It has not come back yet but only has been a week since the reset. Probably developer needs to intervene to add to an update?
