Hello,
I own an HTC One M8 (european version), which, unfortunately had a problem with the main camera: buzzing noise and unability to focus. I have already looked at the internet about this, and it looks like it was an hardware related problem which would require the camera replacement.
Therefore, I took my HTC to a phone repair store, however, it took a lot of time to repair, since after replacing the main camera with brand new units for three times, the phone didn't recognize the camera (black screen and returned to the main screen).
After that, they tried to replace the combo unit (main camera + duo camera) and the phone finally recognize them, however, there's a recurrent error saying "Duo camera is blocked, please make sure all lenses are uncovered", when the lenses are effectively uncovered. Additionally , when I cover the duo camera, the error doesn't appear (previously, I remember that it would appear immediately), and the photos, which were very sharp, now look unfocused and sometimes, like if they had some kind of halo light effect.
The guys at the repair shop even tried the new main camera with the previous duo camera, without any luck (the error remained)..and they just gave up about it (no charge), since they didn't know how to solve it (in Portugal, HTC phones are not very usual).
Just for your information, the phone is stock (official firmware) and was already reset several times (hard and normal reset) with no luck and, despite the fact that the error doesn't appear in safe mode, for me that's not a solution even because the image quality is not the same anymore.
Has anynone already solved this problem? (I've already looked in the internet, but didn't find any solution for this situation)
Thank you in advance.
Best regards

Hi all, appreciate if anyone could help me on my issue. When I make video call to my friend, I can see his cam but he can't see mine. It seems like the front cam is not turned on as I myself also can't see my cam displayed on screen. I am not sure this is the hardware (front cam) issue or firmware. I am using HTC Hermes WM6.
Or is there any way for me to check the functionallity of the cam?
hello i have tha same problen since last days
so u mean previously ur cam is functioning? Any idea what is happening? Any expert or user who faces this before and know how to fix? Or at least anyone know how to test the functionality of the video cam (hardware).
your solution is:
the FLEX cable on the front cam is disconected, call a local lab or do it yourself.
I have uploaded a solution to the main hermes forum in the past 4 months.
i had this problem before. it's one of the buttons on the screen during a video call which you need to enable your own camera for the video call.
The connection of the camera to the main board is known to come loose from dropping the phone, etc. If your phone has taken a few tumbles it's highly likely this could be the case, if you've tried everything software side and you feel skilled enough, open it up (void your warranty) and plug it back in (it's quite straight forward, you just need to be very attentive and careful). Otherwise, send it some where to get fixed.
Hello,
I have a strange problem with my phone. When I try to use the front camera (using any application that makes use of the camera) I get the following error: "Unknown error by ErrorCallbBack".
Even though I am not using the camera often, I know I have used it before to take photos. I haven't upgraded the ROM or made any changes recentrly, so this is very strange.
Sometimes, after a few restarts, the camera works again for a couple of times and then fails again.
I googled the problem and pretty much everyone says it's a hardware problem. I was just hoping if someone can tell me something different cause I don't have a spare phone and can't afford to be without my smartphone for days.
Thanks,
Aris
A few days ago I have ordered and then replaced the LCD of my Zenfone 2. Sending it back to repair the display was as expensive as buying a new phone, so I decided to take the risk. I followed the instructions I found on the internet and I succeded. Both touch and display work after replacement, and all other components work too, except for camera functions. Now when I open any camera app (Google Camera, Zenfone Pixelmaster camera and so on) I get the infamous "camera failed to launch, please reboot your device". After cleaning up both application cache and system cache (I have even tried flashing an older firmware version) I decided to check both the flat cables connecting the front camera and rear camera to the phone's motherboard, with no success.
Any clue about how to proceed ?
Any chance that trying a different ROM (such as Cyanogen) might fix my problem ?
I have read that many users are experiencing that nefarious camera message, however I haven't found any effective solution so far, and without a clue I can't figure out if one of the two cameras is broken or damaged...
Suggestions ?
Thanks in advance and have a nice day

UPDATE 1: installed CM 12.1 following tutorial. Everything working except for camera. Tried both Google stock camera app and A Better Camera (free trial). Google stock says "cannot connect to camera" A Better camera shows a black background and does nothing else...
UPDATE 2
I just received a spare Zenfone 2 from another guy that, after breaking the screen, decided to sell it for spare parts instead of repairing it.
I have turned it on as soon as it arrived via mail and..guess what ? Camera issue is there too!
I have tried the following:
1) swap both camera modules and motherboard to my Zenfone 2
2) vice versa (put my camera modules on the newly received motherboard)
3) hard reset and reload all system images on both phones.
Issue is still unsolved. I'm starting to think that the camera problem is a "sort of anti tampering" implemented by Asus.
As soon as you unscrew the phone, something breaks - or at least detects the tampering - blocking the camera.
There's no other way to explain...
Any suggestion ? Did anyone effectively solved the problem ?
Please, don't leave me alone in this thread..

ZENFONE 2: camera failed to launch
Dear Azrahel
My Zenfone 2 phone exactly encountered the same problem, probably because of a software update/installation and so on. I simply rebooted the phone into the SAFE MODE (simply long press the power button then LONG TAP the shutdown then confirm the reboot into the safe mode). In the safe mode I found that the camera works normally. Then I simply rebooted the phone (in order to enter the normal environment) and now the camera works! I hope that you can fix the bug by this simple process.
Did you find a solution for this? I'm encountering the same issue after I replaced the display. The connectors seem to be in well. Maybe I broke something small internally without even knowing and that causes both cameras not to function.

have you resolved? i have the same problem
I have the exact same problem... my screen broke, I got it fixed, and the camera stopped working... tried the safe mode method, didn't work. I am now running cm13 on my phone, and camera still doesnt work.
Zenfone 2 ZE550ML
Did anyone find a solution yet?
My rear camera suddenly stopped working. My phone didn't get any hurt in nowhere, just suddenly it stopped working. I was takin photos since 10 minutes before, I locked the phone and I noticed that Torch tile disappeared. I thought it was a bug and I didn't care anymore. The day before I noticed that even rear camera stopped working, I was trying to take a photo but the "change camera" (from front to rear) disappeared in every camera app I was using, camera apps opened by default with front camera opened. I tried to reflash ROM thinking that it was a ROM problem (even if I was using the same rom since months ago and I've never had any kind of problem), no results. Reflashing everything starting from stock firmware, no results. As a last hope, I tried to replace the rear camera by buying a new one, but the problem it's still here. Could someone that experienced the same problem, tell me where the problem could be? Or maybe some possible fixes, every kind of help is appreciated. Thanks.
Same
I have the exact same problem. After wiping the cache the rear camera is recognised and I am able to take a picture with it (which is not saved into gallery) but about 5 minutes later the option to switch to rear camera has gone and all camera apps (including social media such as snapchat) is stuck on front camera. This leads me to think it's not a hardware problem but rather that of software with which I am running cm13 nightlies that I have updated every day for the past week in the hope it will be patched.
I have this exact same problem on my d855 too..!
Sooooo frustrating, I've been looking everywhere for a fix, tried full factory reset the other day (I'm running full regular stock with no root or anything), and sadly that didn't work either... I'm glad to read someone has tried changing the camera hardware, cos that was I step I've considered taking, but I now know would be a waste of time and money...
But still, the problem persists..!

I don't think that's a software problem simply for one reason: I'm on the same rom and kernel since months and camera worked fine. It stopped working suddenly with no reason.

Yeah now you made me understand why the camera worked for some minutes. I'll try clearing cache after installing new camera module. I'll report the result. Thanks anyway.
Edit: It's not working. At first boot, systemUI doesn't load well, when I reboot everything works fine but rear camera isn't working. Maybe late I'll try with phone's camera. Now I'm using the new one bought some days ago.
same here!!!!! I'm using LOS13.1 on my d855 and i can't fix it... any idea?
What OS are you guys running? Is everyone experiencing the issue on Cm13?
Also try cleaning the camera connections really well.
I have same problem. Although i expirienced it first time on Lineage OS 14.1. Now 30B, but it still not working. I was listening to music through external speakers, and suddenly it stopped working. Music app was "playing" but i couldnt hear anything and when i exit the app my phone just stops working and starts being laggy as hell. Later that day i found out my camera is not working. I tried reattaching cam connector but it did not work...idk if i should order a new camera or it might be a software fix or something
same problem
happened to me after upgrading to 6.0 , downgraded back to 5 with no luck , even opened my phone and released and reconnected the 3 cables inside with no luck at all . don't know what to do
It's "good" to see other people with the same problem as me.
I replaced the camera and it still won't work.
I'm afraid that it might the problem with our motherboard...How can software block our camera even tho all of us fully reinstalled ROMs/Modems etc? It would be awesome if dev would see this and tell us what is the actual cause of this
If you reinstalled the entire OS using a TOT method, no files are left behind. This is more likely a hardware issue.
The Camera module is extremely close to the problematic hot chip on the G3 so it's not impossible something got messed up.
I have a d852 in Canada that doesn't get hot and I'm having this problem too. Going to order a new camera since I know this is a hardware issue. Hopefully fixed the issue. Not cool having no rear camera or flashlight
It's impossible Every G3 gets hot...you either are not heavy user or idk...but every G3 that i've held had the issue of overheating at some point...and indeed it can ruin everything...imagine 120C on your processor...that kills everything around it...idk if my processor got that hot as i've seen in some cases it did on internet, but it did go up to 90ish...and that is too damn hot
FIX ISSUE be Done

Hi,
Last year (in august) my phone was stucked in a bootlop so I've sent it to the repair shop. (it was, and it is still under warranty so it was repaired by the official LG partner). They've changed the motherboard and fixed the phone. But from that date, my camera (both front and rear) are experiencing some weird problem(s).
1. i think that are less focus points since the phone was repaired
2. it is harder to get automatic focus
and the biggest problem is:
for the first couple of seconds, i get some weird static interference (i don't know if this is the correct term but you can see on the link, that for the second or two there is some interference)
1drv.ms/f/s!AlZuIPfxtUJcyypdpnKgJ24bHFxb
I have tried factory reset, and force stop camera, and even different camera apps but on every single app problem persists.
I think that the main problem is "focus" because when camera is focusing for the first time that interference appears. When camera focus, there is no more interference.
But as the phone is still under warranty, should I sent it to the repair shop?
Is this a common g4 h815 problem (because i didnt find anything when I searched for this problem)?
Is there maybe a way to fix this problem without sending it to the repair shop.
Thank you all in advance for your help.
i got the same problem after replace, and a nother problem is when i dont have a god coverage and my mobiledata is enablet i get interferance and phone gets so crazy (ghost totches)
Mine had a bootloop as well send it out for repair they swapped motherboard.
Ever since I have various problems. Now with camera focusing doesn't quite work the way it did before sometime it just won't get sharp.
Also zooming the camera on max then take a picture causes the camera app to crash
And when I take a picture in very dark environment my phone crashes and won't startup again. I need to plug it into the charger and then start it up again.
Last week, a new problem appeared. Phone is Ghost ticking at random places on touchscreen tried a factory reset didn't help.
@DollarBlingsy @neobdium
have you sent the phone back to the repair shop?

I'm thinking about it. But the problems have to be found at repair service, and camera app is not always crashing, and phone doesn't always crash when taking pictures in dark environment.
Ghost touching doesn't always happen as well.
So I'm doubting they will recognize them as I send it out for repair because it looks fine at first sight.

That's what I was thinking. But then I took pictures and videos of camera and I will also send that to the repair shop. Because that static interference appears every time, so I think they will recognize when they fix the problem
That's probably a smart idea!
My ghost touching have started when I reset my phone to factory default.
My camera crashes have been reduced by 70% with factory default
Thinking about unlocking and rooting and flash custom ROM since I believe there is a software failure that causes my ghost touching.
Anyway my first and last LG phone such drama phone good specs and awesome camera. But quality and software very bad
