[Q] Front facing camera issue

Hey,
So I cracked my screen, changed it with OEM new parts, and worked great for weeks after the installation.
Now, I'm having camera issues, back camera works fine, but when you switch to front facing camera the app freezes and crashes, and I get cant connect to camera black screen, and at this point the back camera wont work either, if you restart and clear data on camera app the back camera works again, but front facing will never work. Currently, I;m running stock rooted but I've had this issue with rooted custom roms and stock unrooted. I'm not sure if this is related to the screen change or not, but it worked great for weeks after the screen change. and, I;m having the same issue with other camera apps too, no snap chat installed nor any other apps that could conflict.
Any help would be greatly appreciated
Thanks!

I am currently dealing with a similar situation. Did you find anything to help fix the problem?

This is almost certainly due a little piece of tape coming off of the ribbon cable. I happened to solve this by cutting a small piece of scotch tape and wrapping it around the ribbon cable so that the underside of the cable is not making contact with the PCB.
I know this is a super late reply but I hope it can help someone in a similar situation!

Hello. So i had the exact same problem as OP. Got my screen replaced (not by me), but a few days after that i noticed that my camera would freeze when trying to change it to the front facing camera. i had issues with messenger and the normal app. i did a few system restores and even unlcoked and installed custom rooted Roms last night. Still freezing on the front camera.
I'm now positive its a hardware connection issue. Anyone else have this issue? I feel i should open the phone and try to fix it.

[Q] Warning: Camera Failed. Can anyone fix it?

I am having a huge problem with the main camera on my Sprint Samsung S5. Every time I try to use it, I get the notification "Warning: Camera failed." It was purchased on the release date (I think 4/11/2014). It was a known issue for Verizon and I think Sprint phones for this to happen but mine is having this problem 10 months later. I have cleared the cache, cleared data, wiped cache and dalvik, done a factory reset, installed MOAR 6.0, CM12, MOAR 2.2, removed SD card after having flashed a new rom (so no other apps could prevent the main camera from working), disabled the Samsung camera app and tried using Google Camera, and nothing has worked. Today I went to a cell phone repair store and the technician said he tried three main camera sensors and two front facing camera sensors (just to allegedly rule out a hardware issue) and could not get any of them to work. The front facing camera works in Google Hangouts but nothing seems to get the back camera to work. I don't even recall dropping my phone and there's not a scratch on it but one day the main camera decided not to work. It wasn't even after flashing a new rom. Does anyone have any ideas?
Thanks,
Richard

Samsung warranty
We received a service bulletin a while back about this specific issue and its a hardware problem . So your best bet is sending in to Samsung or depending on your carrier you can call carrier and they will swap it out for you.

Thanks for your reply Dhulqarnain. I have rooted the phone and tripped Knox so I can't send it back to Samsung and Sprint is requiring me to sign up for their protection plan (I think through Assurion) to take care of this even though it seems like it's a known issue. Do you have any other suggestions?
Thanks,
Richard

Same problem...inexpensive solution
I've had my sprint s5 for nearly 2 years now, and I recently started having the same exact issue. After extensive research I'm afraid that I must confirm it is a hardware issue. I'm in the same boat as far as knox, my friend...and that leaves repair as our only option. The good news is that it supposedly isn't too difficult to replace, it actually connects like a laptop keyboard, or an ipod hard drive connects (a ribbon type connector). It probably will be a ***** to get it connected, but the even better news is that eBay has our s5 camera from a few dozen sellers ranging from $6 to $15. :good:

Thanks Gmoney1234. I took the phone to a cell repair shop and they tried six different main camera sensors and two different front facing camera sensors and could not get it to work. So that means there's something else going on with it.

dead camera....twice

Dear all,
A few days ago, my N5's camera stopped working and none of the usual solutions (reboot, clean data and cache of camera app, even complete wipe and change of ROM) did anything to fix the problem. So I went on ebay, and bought a replacement back camera, fitted it and all was well...for a day!!! It looks like after just one day (and nearly no use at all) the new camera has already stopped working. Is anyone aware of what may be causing it, and of a way to fix it? or is it time for a new phone?
Thanks for your help!!

Is it possible the camera connction on the motherboard is a bit flaky?

Thanks for your reply. I thought that too after the second camera went wrong. I re-opened the phone and checked the connection, and from what I can see it seems quite solid. I am not sure what could possibly be going wrong that causing 2 camera modules to go bad in quick succession though. While the rest of the phone works perfectly.

Maybe it's just coincidence. I guess you could try a third camera to see what happens.

Can't connect to camera
My camera quit working the day I updated to 6.0.1
At first it would work for a few hours after a fresh boot. Now it won't work at all. I replaced the camera module with a working one and it worked for a few hours then died. Now all I get is "can't connect to camera". I'm convinced its related to the marshmallow update.
Safe mode doesn't help. Factory reset doesn't help. Third party apps still let me use the front camera but the rear is dead. I think I've reached the end of the road buying nexus devices and beta testing OS releases.

Maybe it because of your sd card

Initially I thought this may be a normal issue of age of the phone, but the fact that a few of us are bumping into this so shortly after the marshmallow upgrade makes me think maybe the 2 things are related.
I suppose I could try and install a lollipop rom and buy yet another camera module.

The only component that should face problems in a persons lifetime would be the battery. It is a shame that companies and people treat this stuff as disposable.
OP and others who cannot fix this through software, or a small hardware change, this must be a hardware issue. Something on the mainboard is messing with the camera. Others are running stock marshmallow fine, to rule out any software issues, wipe all and flash new (manually wiping and flashing each partition from fastboot would be best). Report back.

Thanks for your reply. Done, but to no avail. Infact when you flash from fastboot the camera app is not even installed and the torch does not show up in the notification bar.
It is definitely a hardware issue, which is not resolved by simply replacing the camera module, as that seems to break again in a short amount of time. Not sure if I feel investing in a new mainboard and a new camera module.

How can I revert sensor software

Ever since I upgraded my maxx from 4.2.2 I have had problems with it shutting down. Sometimes I will get the warning that it is over heating even when it is cool too the touch. I remember after upgrading that I had a message about the sensors and after many hours or reading about similar issues from other users I feel that it 'may' be an issue with the sensors.
Since I'm on 4.4.4 I can't fully downgrade so I would like to know if anyone can help me to pull the original sensors from the 4.2.2 and flash them. I don't want to get rid of the phone since it is otherwise in great shape.
Can any one help?

OnePlus6 No Signals, Camera and Flash not working

I bought a Oneplus6 online with the screen and back glass broken. The Guy I bought it from had it kept in a drawer for four months before selling to me. Once I got the screen replaced, I couldn't charge the phone since the battery had died. After replacing the battery and factory resetting the phone. I found out that the camera and flash were not working. Also the phone showed both IMEI numbers and recognized the SIMS I put in correctly but when i try to dial it says turn off airplane mode. When I check the SIM status it says Radio off.
I tried flashing a few stock roms using this thread https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109. And some how the phone started making and receiving calls. but once I got the OTA to the latest Oxygen OS it stopped again with same error.
If I try TWRP to flash Lineage ROM or even stock ROM my phone either crashes ( Lineage ) or goes into endless boot animation ( Stock ROM ). Its currently just "ipod".
Looking for help / suggestions on how to get all things working again.
P.S. I have tried new Camera's ( Front and Back) without any luck.

*#808# to check all the components, retry to flash with msmdownloader to see if it helps

Thanks, I have tried almost all the msmdownloader ROMS available. No luck. I did get the signals working for a while after one flash but then it went away when I updated to the latest 9.0 OTA

The strange thing is that I got both the slots working for a short while only the camera and flash were not working. I did an OTA and lost both camera and mobile signals. It shows radio off and I get cannot access camera when I try to launch the camera app. Is there an even lower level tool then MSMdownloader which fixes the hardware drivers?
I have even tried the Hydrogen OS "enchilada_22_H.07_180513" ROM without luck. I think the problem is software/firmware related as I did get the phone working for a while.

Got the front camera and one of the two rear camera's working. Apparently the rear camera was faulty and replacing it with the new camera worked. The flash started working as well. But a new problem has surfaced. The bluetooth , although turns on and shows that its discoverable, doesn't find devices and my phone doesn't show up in other devices as well. Wondering if this is related to the lack of GSM signals( Radio off).

Ok, turns out its hardware issue. Lesson learnt, don't buy damaged phones!
Thanks for help @Chinaroad

Sorry for you, it can happen. The good thing is that replacement part are easily found and cheap on aliexpress like the camera module, for BT i don't think so cuz it's built in. **** happens, and again sorry for you
