THL W3+ does not recognize rear camera (main camera)

Hi guys.
I have bought a THL w3+ from geekbuying.com 6 months ago. Almost from the beginning I have a problem because randomly Android does not recognize the rear camera and when I start the camera program is only posible to choose the frontal one (2Mpx). It doesn't appear the icon to change between them.
I have done many tests with inconclusive results. These are the facts:
* The mobile phone came to me with Thl.w3.12.1113.6577.COM.EN ROM installed.
* The mobile phone was rooted it
* Randomly the camera program crashes and since this moment is not possible to use the rear camera. Even if I restart the mobile phone.
* I've tried with different ROMs with no success
Sometimes, the camera has returned to life.
Once when I removed the battery for a minutes, after restar the camera was working (till next crash few days after). It didn't happen again, I've tried to remove the battery and It doesn't work
Once when I replaced the boot partition with the original ROM. It didn't happen again
Once suddenly in a normal restart after the battery ran out. It didn't happen again
As you can see, there are not clear symptoms and I don't know what else to do. Sometimes I think is a sw problem and sometimes I think that is a "battery-saturation" for having the mobile phone too much time with no restart
Any advice would be greatly appreciated.
Thanks in advance.

Nobody?
Thanks in advance

Sorry I have no idea why yours behaves like that.
I've had this phone since November 2012, only recently did my front camera stop working
once i switch to the front camera in the camera app, it freezes.
I tried another app called Cymera, the same result.
But my rear 8MP camera still works.

You can ask customer service for the solution.

[Q] Front camera exposure bug

Hello guys,
I don't know if it happens to you, but I've got some ugly bug on my front camera. Wherether I'm trying to shoot photos, I've some good exposure in preview, but after I shoot a picture, the exposure goes under or over exposure, but never the one I get on a preview screen (before hitting the button). Is this a known bug and is there any way to fix it.
I didn't see anyone complain about it, so I think it's not common. By the way, I tried to use different roms and diferent camera apps, it all the same.
The only thing I found on the internet is this site:
https://community.republicwireless.com/thread/26076

Yea, it's a common bug, that haven't been fixed.
To me it only happens in very good daylight and the photos end up overexposed, HDR doesn't help.

In the one plus one camera app this bug is not there! In all others that I have used its there!

So I have this bug too, any pictures taken with the front facing camera outside during the day are almost entirely white, you can just about make out what the picture is of. But the preview and movies taken with the front facing camera are fine suggesting it's software. I have no screen protector, no case, unrooted, KitKat out of the box. Tried different camera apps with no difference.
I know this was posted a while ago but any updates on this? Can lollipop change anything? I have a moto g LTE in the US so no L for me yet. Can I adjust settings in the camera app (I downloaded the apk for the moto camera that has settings access)?
This issue, along with the multitasking problems that mean I can't even listen to music while surfing, have tempted me to give up on this phone entirely.

Dunno if it's fixed in Lollipop, but I can test. I just don't use the front camera much.
I got no such problem with multitasking at all, even on Lollipop, let alone KitKat that was way better in the memory management.

Thanks for offering to test it - I'd really love to know if L makes a difference. I don't often use my front facing camera either, but just knowing I don't have the option to use it is seriously off putting. Last week I ran into a friend of mine I hadn't seen in years, and after trying to take a picture together you couldn't see either of our faces. It was so disappointing.
As for the multitasking, it seems like some phones have an issue while others don't - all I know is that when I have Google Play open, launching Chrome causes Play to close after 30 seconds, no crash error or anything. Same with the home screen having to redraw after exiting almost every app I use, and Chrome tabs reloading every time I switch between them. I've gone as far as uninstalled the memory hogging facebook and other apps, but the problem persists. Painful is the only word for this phone at the moment.

Tested and I couldn't reproduce the bug on 5.0.2. It takes pretty normal pictures now.
Can you tell me if on KK you can enable HDR? On lollipop this is not accessible at all.

I have hope for the lollipop update then! Yes on Kk you have three options for HDR, on, off and auto.

Camera Focus lock issue.

Hi everyone, i want suggestions guys, my opo's main camera focus is acting weird since last update, it was working great on 44s and then i updated it and the camera stopped working, cell phone showed theres no main camera attached to board, like camera app opened with front camera on by default, and there was no camera switching button. So i decided to deassemble the device thinking that it was some hardware issue, but everything looked fine in there, so i just disconnected and reconnected the camera sensor ribbon/connector to board just to make sure, and restarted device, canera came back somehow, but since then camera focus lock became horrible, anything out of 2feet range is blurred and out of focus, when cell auto focuses, theres a perfect focus point but camera locks its focus after that on blurred image, yesterday i flashed back to 44s and camera focus became a bit better, not perfect but way better than before, so now i think it is not entirely a hardware issue, something in camera firmware or drivers, can somebody help me on this issue please?

Same as mine after updating to lollipop.

guys please help saw something in the youtube about nexus 5 having the same issue fixed by tasker app running shell script. killall mm-daemon-camera tred but not working maybe some dev can help us use this method to fix the issue.

Camera and video playback problem when logd process running

Hello everyone,
I'm on a new Lenovo K3 Note and I'm having a little problem with my camera. I'm running Androium 5.1 but the exact same thing was happening with every other ROM I've tried, including the one from Lenovo. Sometimes when I open an app which uses the camera, from google camera to messenger, the camera freezes- it is still working but updating very slowly like 3fps and no its not related to ambient light.
After monitoring the running processes for some days, I noticed a process called 'logd' running while I was using my device's camera. Sometimes this process becomes the most resource-intensive process in the system and that's where the camera/video playback becomes extremely laggy. I did not notice this in safe mode but I cant possibly be 100% sure since it is quite random, or at least it look random to me for now. Could this be an app causing the problem? Any help finding the one responsible?
One more thing I've noticed, but this could be my imagination, its that the more I use the camera the less frequent the problem becomes. But again, dont take my word for it.
See a screenshot here i78.photobucket.com/albums/j97/nndth/Screenshot_2015-11-24-09-10-20.png~original
Any advice ? Thanks!
PS: I did try the Lenovo K3 Note subforum but noone could help me there, figured I might as well try to post here

Rear Camera + Flashlight keeps getting disabled... Why ???

I have had no issues at all for almost an year with this phone. I was running oreo ever since I bought this phone. Suddenly, a day or two before upgrading it to pie 9.0, I found out in my Snapchat app that there was no back camera sign. First I thought, some weird snap update, but then I found out in system Camera app, it was even not showing the back camera. Whenever I would click on the rear camera sign from the top in Camera app, it would keep on swapping to the frontal secondary camera and then back to the primary frontal camera but no back camera was working. Also I found out that my Flashlight icon is hardened or greyed out, like it's been disabled forcefully. I can make it work using some other app, but it is frustrating why this is happening.
Now I am on android 9, rooted, and this problem keeps on coming and going. At times the back camera won't even work or open with the error "Camera not working" etc. Sometimes, the back camera would work but with only 3 weirded resolutions, like 12MP, 16MP, and some other. and the video mode will be extremely large or zoomed in at 16MP. Suddenly, the camera will start working normally again with all the perfect default resolutions. I tried everything from SAFE MODE to CLEARING THE CAM APP, RESETTING THE APP, but nothing works. All it seems like that camera has suddenly came to life and has a self-consciousness and a mood which it is controlling itself. Sometimes it wants to work and at times, it simply just gets disabled. Any idea what could be the problem? I am rooted using MAGISK.

Simular camera problems with Lenovo tab v7
I have a Lenovo tab v7 with almost the same problems, the rear camera wont work but occasionally the front camera works and the flash LED is dead.
Running Android 9 Pie as well, but not rooted yet.
Any ideas about what we can do about it, is the camera hardware due to be replaced?

It suddenly started happening almost a month ago, I was on oreo 8 and then upgraded to pie 9 but the problem persisted. It kept working for few days and then started to make problems again. I tried to read many forums for android users with the same problem but still haven't found a single complete fix for this problem other than that the rear camera needs to be refixed. But I am finding it hard to believe that even if camera was getting bad, there is no point of FlashLight getting greyed out/disable from the notification bar. It seems more like some kind of a process is not releasing the rear camera and flashlight module/process.
