Hey everyone,
I just bought a Motorola G4 Play for 50€ and I'm trying to fix a problem with the back camera.
The previous owner said it's a software problem (?)
It isn't working (black screen), and whenever I try to take a picture, the phone reboots
In some cases the phone even bricks when trying to take a picture
Same problem with stock rom and LineageOS (Android 7.1)
Front camera works as intended though
Do you think it's a hardware problem? What else could I try (changing kernel, ...)?
Thanks :silly::good:

The camera worked until yesterday. I flashed with wm6.1 and the problem remains. Here is a picture:

Hard to tell if that's a hardware or software problem. Try:
hard reset
flash another ROM
and finally if all that fails, I think it possible that the camera push in connector may be loose. Not a difficult fix.

Looks to me that the camera driver included in the ROM isn't fully compatible with the hardware. I'd try another ROM or go back to an older one that you know works.
Of course, I'm no expert.
I solved the problem. While the camera is running i removed the battery for 20-30 sec. Obviously it is software bug.

Hello,
I am new here and hope to find an answer to a problem i have with my Acer A500.
I am very happy with this tablet but when i wanted to do some video call with Skype i notice than my front camera doesn't work.
I get a green screen with a lot of noise and sometime its like i see some of my icons of my home page but a lot bigger.
Does anybody have the same problem, i want to have it fix in the shop but only when i am certain it is a hardware problem.
I don't want to miss my tablet for several weeks.
A factory reset did not make any difference.
Hey, sorry to hear that your front cam isn't working. I haven't heard of any similar issues lately. What version of Android or ROM are you using? Are you rooted? Ever dropped your tablet or anything? And lastly, have you tried using the front cam in another app such as the stock camera app? It could be a problem with Skype.
Camera
I am using Android 3.2 and my tablet is not rooted.
I am very careful with the tablet and didn't drop it.
I read somewhere that sometimes the camera socket can come lose ?
The stock camera app also doesn't work.
So, many it is just a hardware problem and i should bring it back to have it fixed.
Thats odd that you have that problem, because i have almost the same one, only thing is im rooted on cm9, and it does it on my rear facing camera....kinda something to think about
That's why i am not convinced that this is a hardware problem.
I am waiting for Android 4.0 to see if this will bring a sollution, if not i have no alternative than bring it back to the shop to have it repaired.
Maybe it is just a lose connector but it is strange that nobody has a sollution
Can anybody show me or tell me if i can check the connection with the front camera.
Is it easy to reach it when i open de back of the tablet.
Best and easiest thing to do is a factory restore, do that, and if it is still having the issue then send it in.
camera
I did a factory restore but nothing changed, so i agree that i will have to bring it back.
I just hoped for a quick fix thru software.
Thanks.
Problem + ICS install
I got ICS today everything worked fine after installation except ... the front camera.
So it definately time to go back to the shop.
Hello again
So i got a i9505 s4 dirt cheap (20euros), the screen was broken, last owner said it stopped working when he tried installing cyanogenmod.
I ordered new screen(original), installed stock rom and it got stuck in sview, i tried everything and nothing worked.
Next i tried rom called aosb (i don't remember if its the correct name, similar to cyanogenmod) it got me to home screen, for 15sec it worked great but then screen went black, phone was still going but everytime i tried to unlock it went black again.
Next i took phone apart, maybe i missed something or frogot to connect, but everything looked good. I googeled for possible problems and found that the proximity sensor(next to the top speaker) maybe broken, disconnected it and still same result. For testing purpose i disconnected front camera and phone worked, but only for 20min when the android tried to update gapps and then i was stuck at not able to unlock again.
Took phone apart third time, cleaned all the contacts etc, installed cyanogenmod and it works, but without front camera.
So my questions are
1. Has anyone ever seen anything like this?
2. Is there a way to use back camera without front one being connected? i can live without front camera
3. Why it goes to sview with stock rom?
Sorry for my english.
I hope somebody can help me.

Well try changing the ear piece module..its something in it maybe.. the proximity sensors are with the earpiece module..
1. Sview random appearances have been noted by many, there must be more to the mystery of this broken S4. A possible magnet sensor error..try disabling it via the xposed modules..anyhow.
2. Well you disconnect the font cam and everything works fine? Eh..never heard something like that..
3. Maybe because of a broken/weird magnetic sensor. As i said..
Plus are you sure without breaking rhe flex you removed and replaced and removed..
Your front cam not working could be because of a bad connection too..
Best is to try *#0*# in the phone menu and try testing the front cam and everything to check whether everything works fine
All the best
Press Thanks if I helped
Sent from my Samsung Galaxy S4 via XDA app.
Hello there to all.
I´m newly registered to the forum, although i´ve been using it to search, learn and use roms in my Samsung s3 for some time now.
I´ve bought recently a used S4 i9506. At the time i tested several key points of the device to check if it was all working, however (and don´t ask me why because i cant explain it), i completely forgot to test the cameras.
My problem is the following. Everytime i try to access the camera it says that camera failed or something like server connection failed. I´ve tried every single resolution i could find on the internet and so far all failed to solve it. The problem seems to be in both cameras, i think, because when i try the code *#0*# both Mega cam and front cam give error. Here´s what i tried so far:
- Soft Reset/Hard Reset/factory reset;
- Cleared cache both from boot and manually erasing cache from com.sec.android.gallery3d;
- Tried 3rd party camera apps from GooglePlay;
- Tried the RestartCamera.apk;
- Tried 3 different firmwares for i9506;
- Tried rooting it and then flashed several different roms;
- Switched the rear camera with a new i9506 rear camera module that i bought;
- I cant also test the cameras, because when i use the code *#34971539# they bring a menu on which i can´t use almost every option (see image);
http : / / rghost.net/6Zby4zXFD/image . png
Anyone have any other possible resolution?
I´m thinking on maybe buying a front camera module. Could that do the trick? Could the front facing camera not working properly make the rear camera fail as well?
Thank you for the attention to all who took the time to read.
So far 60 people read and nobody answered. ... is it because you don´t know what else i can do? I´ve been reading the problem may be from the motherboard. What can i do on the motherboard to make things right?
Thanks again
Be patient my friend someone will answer soon
Hi,
I've got the same problem with my s4mini. Both cameras aren't working and all the solutions you explained don't solve it.
I'm thinking about buying another S4mini with broken Display in order to change the motherboard. This might be the only possibility to solve this......

Hey there m8.
I know the feeling, right?!
The thing is that for a faulty i9506 model i could almost buy myself another motherboard and mount it, but i was hoping to find some other solution, maybe even some electronics expert opinion on what i could do in the motherboard to make it work again. There are some videos on youtube that teaches how to change some components on the motherboard to solve problems like dead smartphone or constant auto reboots. Also, finding a faulty i9506 model isn´t as easy as finding a regular S4. :crying:
Thx for sharing the problem and for the opinions,
and greetings from Portugal
Today i've changed the mainboard aaaaaaand -> cameras still not working
So i started to change the front cramera and the ear-brightness-sensor from the old s4 mini with the broken screen into my working one. And now both cameras are working again!:good:
I think the cause is most likely the brightness sensor which is combined with the ear speaker. This could explain why both cameras are not working.
I'm not completely sure due to i changed the front camera also. However changing the main camera did not do anything as mentioned above.
Maybe i should mention: A few weeks ago i've changed the earspeaker-brightness-unit because the speaker wasn't working anymore. Right after this both cameras stopped working.

Thank you for the update on your situation m8. That could be some relevant information there. Can anyone confirm if the sensor is the same for all s4 models? If so i could find more easily one from another s4 model and try it, for the sake of desperation.
cheers
Hello.
Some years ago, my screen died and becase of I had a good motherboard, I bought another H815 to sustitute the screen.
Then, some components like camera or speakers did not work, so I tried to use the components that came with the H815 I bouth, instead of use the components I had in my old H815. By this way I achieved my phone to work fully.
Some months ago, my motheboard died, and I bought a new one(I think new) from Israel in Ebay.
I had the same problem, this time, only with camera. I tried both rear cameras I had. With one unit, the app show that this don´t work and with the other I only can see strange and purple lines. In both situations, the front camera works well.
Something that is difficult to understand to me, is that in some apps like whatsapp, one of the cameras works in some occasion ( I can see all well, but too vertical purple lines on white things in the image).
I tried apps like google camera or to installing the native lg app too, but I can´t do anything to solve the problem.
Anyone know how to know the compatibility between cameras and motherboards in H815 terminals? I tried to bouth a third camera but I had the same problem. I know the cameras are not damaged and work in other terminals.
Do you think if it is possible to solve this installing a different rom on my H815? I tried different rooms on my old first gen Motorola Moto g, but I have any experience with H815, can you guide me some, if you think that this is a possible solution?
Thanks a lot!

Any Help?
I changed my m/b too on my G4 from a seller in taobao (815t->F500) It works great, camera were fine. So I think it might be you camera module or faulty m/b is at fault... cos changing m/b should not cause any problems.
