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.

Hi
Basically been having this problem for a while now and its starting to bug me. I rooted my phones ago now, and until recenlty the camcorder worked fine on all ROMS, however recently been facing a big problem with it. Every time I launch camcorder on any ROM my phone will freeze and have to take battery out and restart. I unrooted it and installed stock and it worked fine (so it can't be the SD card) re rooted again installed RSK and boom same problem. Does anyone have solutions to this?
Thanks in advance
If I remember correctly, the aroma installer gives you the option to change between two with a warning about one not recording. Also, have you tried another third party app to see if that works? You may also want to try taking the battery cover off and pressing (not too firmly) over the camera window and on the metal sheilding around it. It might have slightly disloged from the upper board but try the software first.
If you start noticing the notification LED, receiver (earspeaker) or camera flash not working as well, then it may need the upper board reconnecting to the main board and you should send it in for repair, but this is a pretty thin possibility, as I said, software first.
Hello,
my GF just got her brand new zen phone 2 and it's front camera isn't working. The first thing we did is tun the automatic update, so I have no idea if the camera worked before or it's the update who messed it up. I'll attach the software and hardware information screenshots.
We have tried to reboot it, update the camera application, force close and clear cache as well as installing other camera application, but it didn't help/work. I have also installed phone tester and it showed information only about the back camera, no front camera (on my nexus 5 it shows both front and back)
Any suggestion on how to fix\resolve the issue?
Thank you

RMA it, that's what the warranty is for.
I suggest if you bought it from a shop, take it back and see if they'll swap it, they have to in Australia if the item is not working properly .
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 all .
Problem method for repair
Issue is easy buy new rear camera D855 or this same conector D820/D821/Nexus5 is this same and all works fine I'm tested on my D855 International
camera From D821 perfect fit and don't had any foult. Great work and my G3 alive rear again :good:
( !!! URGENT !!! Don't put any paper or any dirt this is short fix and maybe You can crack connector camera on motherboard !!!)
If U still like Your's G3 don't put any **** tourial with fix BUY NEW CAMERA couple $$ AND FIX very cheap and clean LG STILL ALIVE :laugh:
(Camera had two IC chip and that is problem (burned or heat out)
Flash light it's well had same problem if U have problem camera,
In camea foult You cant turn on flashlight (software thinking camera all time working if camera is broke).
If u tru turn on flashlight he said (on broke camera) " Immpossible turn on flash light when camera work" !!!!!
Okay, so I'm having some issues with my G3.
1. Issue: Last night i noticed that my rear camera was not working. I was running Lineage OS 14.1. I couldn't rotate from my front camera to rear one, there was no option for that. So, this morning i installed stock MM 30B and i thought that it will work just fine, it could have been a minor software issue..well, it is not working. I also noticed that flashlight is not working either...AND my front facing camera is upside down What in the hell is wrong with that? I've searched for solution but on google but couldn't find it so i started installing apps that leads me to my second issue.
2. Issue: WIFI is SLOW. It took forever to download Facebook app from app store, even though the signal strength was maxed, and my phone was like half meter away from my router...My PC gets 55Mb/s and phone just over 5...
For the camera, i tried to unscrew my device to see if the ribbon cable is not attached properly, but i was unable to find a proper screwdriver...i managed to get 1 screw out, but it was pain in ass so i figured ill take him back instead of continue to take apart my device....
Any advice on this 2 issues? I'd appriciate it

Please reply there. Did the issue occur after you updated your cm13?
Hey guys,
N7105 Lineage 7.1.2 (2017/06/20)
Pretty green to all this. Just reimaged with the latest Lineage, got that working - slick system - only foible this time around is Camera Error ("Can't connect to the camera")
Note, I replaced the back (rear facing) camera with an ebay special recently. The samsung image was ok with it, took photos & clear enough. Cyanogen and Lineage both error out as above on attempting to use the camera.
Pity the backup didn't work. I might end up reversing all the way back to stock at this rate; now, thoughts. Could it be the replacement camera? An N7100 camera, for example? Is there a possible workaround to that - or am I barking up the wrong tree?
I'd prefer Lineage to the stock OS, for sure - if the camera problem can be resolved.

Can't connect to camera is an old cyanogen (now lineage) problem. To fix this i download mediaserver killer application from play store and this fixes the issue.
This error is usually faced if a third party camera app is messing with the main camera. Eg- snapchat.
Funny app that one. It demands SU, eventually #SuperSU notices and I grant it SU access... it continues to demand SU when you try to open it.
Also, it hasn't fixed the problem (yet). Is there a trick to this?
Tried it via Play Store and by APK download & manual install, same results.
*Edit: You've given me a new direction to look in though. Tried safe mode, camera still errors out. Will go through some more steps of this article later.

Do restarting phone solves the problem temporarily?
Nope, no affect from restarting.
Update: Popped the old camera back in, guess what. It works. Additionally, with the replacement camera in I lost Torch function along with rear camera; front camera did work in third party apps, just not rear. Re-installing the original rear camera regained all functions.
Of course, I replaced it for a reason - liberal use of solvents damaged the lens in that camera, I still have to find another replacement. Probably not from ebay though...
Really rocking 7.1.2 and having root access on tap, big cheers to the Lineage mob and the #SuperSU guy; these are great packages, and done just for the love? Crazy guys, good work.
