Focus problem after rear camera replacement

Hello everyone!
Since I replaced the broken rear camera of my GT-I9505 the camera doesn't focus properly. First I thought it was a faulty replacement, but the replacement of the replacement as well as the camera from a different seller show the same behaviour:
The google drive widget for scanning docs focusses correctly, but none of the available camera apps work. As soon as the app tries to focus the focus goes into near mode and remains there with no further movement.
I have factory reset the phone, reinstalled all camera apps, flashed other roms, factory reset again, with no change.
Has anyone experienced this as well?
Thanks for any tips

So little rear camera replacements? I guess I am the only fool that managed to crack it

Hello there
I also have this same problem and done all those same things to fix this. 12cam is now useless. Some1 help us out of our misery! :I

I just picked up the i9505 second hand (first smartphone). Same problem here. I went through 3 camera module parts off eBay... first one was the wrong part (i9500), and other two were supposedly i9505 - same results: camera never focuses. *Sometimes* it will temporarily focus if I moderately shake the phone, even then, only if the phone is tilted upright and not facing down.
Is the front camera unaffected for you guys?

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
Press Thanks if I helped

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

[Solved] Camera issue, bad focus - Huawei P8 Lite ALE (2015)

Hi!
I had a big problem on my Huawei P8 Lite ALE, the camera started taking shoddy pictures, I thought it was software and tried everything I know but always with the same result ...
I thought it was time to buy a new phone but then I decided to try something else, maybe it was some dust or something similar on the phone lens and I removed the back cover and started looking closely with the help of a light bulb. I had the feeling that I had tuning due to its shape and with the help of a precision wrench I tried to turn the lens ... And it worked!
When rotating the lens the lens focus is changed!
I remembered that a few days ago I had removed the back cover of the phone and possibly have changed in the lens causing it to deflect.
How do I tune the focussing?
I turned on the phone, opened the camera application and zoomed in, I was running either one die or the other until I found the better-defined image!
Then he just closed the phone.
Check the images below.

Back camera doesn't work

Hello,
I changed the screen on my Huawei P9, but the rear camera doesn't work. The application crashing (it opens, closes and restarts) and I cannot check if the front camera. works. I have already tried to reset the phone and completely drain the battery. Before changing the display it worked, so maybe I have damage it when I took it off my smartphone.
It's possible? What you think?
Should I replace the camera? Or can be a software issue?
Thanks!
