Rear(back) camera stopped working but fixed!

So after 3 months of having the phone one day I went to use the rear(back) camera and it was black but the front camera still worked.
After trying to restore the phone, it still didn't work..
But then i turned the camera on again, then PUSHED IN the lens a bit from the outside and its working now.
Glad it was just loosed or something.. but if you guys have this problem i suggest trying this first!

Screen dosent work when front facing camera is connected?

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

[Q] front camera not detected!

Hi,
I have a gionee elife e7 not rooted, and my front camera is not working
A few days ago I ve take some photos with it but now the camera app closes when switching rear to front camera. I ve cleaned all data and cache from apps and rebooted. Nothing changed. I was thinking and installed a app named hardware info to see. My rear camera was detected but unfortunately the front camera was not there. I made the same in another gionee like mine and the front camera was there! What can I do now? I have the print screens if needed. I just want some help.
I'm using amigo 2.0 as OS.
I have my phone since March, 2015.
Some Android fan help me plz

S4 i9506 both cameras not working (tried everything i could find)

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);

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

Weird camera bug

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:
