Flash the ROM again to fix your WiFi. While the ROM may help, I believe your camera problem is a hardware issue. You'll have to replace the camera module.

ok i just updated 5.0.1 . and how to flash rom via odin?
Flashing a custom ROM won't help fix your WiFi. You need to flash a stock ROM through Odin, and there are threads in the S4 forums which explain how to flash a ROM. Please use the search engine to find it.
Same Problem...
Just noticed this problem 3-4 days ago. I've done a factory reset and also tested a known working rear camera in my phone - I still get an updating firmware message or can't connect to camera message when I open the camera app. Also, the flashlight won't work and disappears from the pull-down menu in Lollipop. I'm unrooted on an I9505G (GPE S4) running 5.0. Not having any other issues with the phone and have tried re-seating the rear camera on the pins over a dozen times. Cleared cache /data from the camera app, uninstalled upadates, etc. I'm stuck. My best guess is either the board, or software related and I haven't figured it out.
With the OP, once firmware had been ruled out as a problem, the only thing remaining would be a motherboard issue. He had already replaced his camera module.
i just want my camera to work no matter wifi work or not. i m stock lollipop
so kindly suggest me something for camera. btw today i will try to flash ro
Take your S4 in for service. If you've updated the ROM and still do not have a working camera, you have a problem with the motherboard, not the camera module.
M facing really weird issue with Oneplus Two Camera.
1) Sometimes not frequently when I open camera app the screen is black and it crashes with an error stating "Camera unknown error".
At tht time if I use other camera apps i.e. Snapchat, Google camera ,etc..they show black screen too.
Even Flash doesn't work at tht time.
So I hve to restart to solve the problem.
2) When in a dark room or so, when I take picture with flash mode on...the camera screen goes blank and I hve to lock and unlock it to solve the problem. But if happens again when I take another shot.
Is there any solution ? Do I hve to worry ? Is it hardware or software problem and if its a software prob...will it damage my camera hardware or any other ?
I really love this phone ...so even minute errors bugs me
Do I need to replace? ...I don't want to spend my time replacing it coz I hve already replaced it ...I mean ..I bought it from Amazon India and due to a small dent on my OPT on the right upper corner I replaced it and it took me 15 days with lot of calling at Amazon ...so I don't want to do all tht again
Please help
I am on Oxygen OS 2.1.0
Rooted
Titanium restored from a backup of my previous phone I.e. Nexus 4 <--- is this causing the prob in any case?
Have you tried doing a factory reset? Did this happen on OxygenOS 2.0.1? Have you tried other camera applications (google camera) to see if the issue is software related? Do you have a custom recovery?

I am rooted
with custom recovery (TWRP)
Oxygen OS 2.1.0
Nope i didn't try factory reset
and yes when tht problem happens all camera using apps hve black screen after reboot everything works
I own that device too and I am not facing any such issues but here is a fix -
If you are rooted clean flashy the ROM
Non rooted -
Wipe cache partition from stock recivery
And most likely I think the problem is titanium backup of previous phone
DARK SIDE™

i just flashed exodus, stock kernel, opengapps, reistalled my titanium backup, and everything works, no camera issue. so i doubt it's a titanium problem, either... but sorry, no idea how to help
Even after factory reset
Not rooted phone. Did factory reset in recovery mode and tried third party camera apps also, still problem persist
This happens for my OPT too. Whenever I try to take a shot in the dark, it just froze. Until I lock and unlock it again. Weird!
I have met the issue 2 as well. When I take picture under dark environment, the screen will be dark and I have to unlock it again. I am using oxygen 2.1 stock camera app. So I think it should be software bug.
One plus 2 camera issue
I was also facing the same issue but now it is resolved.
Steps. Before clicking a pic in dark just maximize your brightnessto 100% and off the optimization of screen in display.then click a pic..the screen wont get dark..and tje picture will be clicked.i hope it will be resolved in future updates with low and automatic brightness too
Hi all, my Lenovo K920 Vibe Z2 with CM13 was working very fine but 2 days ago stopped work rear camera. I open stock camera but start with front camera only. There isn't the rotation camera to start the rear one. I try others app but same problem or doesn't start. In internal storage i have complete zip rom file (the same) so i can overwrite rom with non loss data but the same problem. There is apk stock file to re-install ? I have important sms data so i don't want to format it ... I already have cleared cache from twrp recovery. Rear flash doesn't work too ! In cyanogen rom widget disappear and if i installa new ak torch it works only with (display torch and not with rear hardware). Hardware is not broken beacause i had another dismount telephone and i attached a new camera hardware and it has the same problems. I don't find news kingsdom row rom's after cm-13.0-20160910-nightly.zip . If i'll try to upgrade to cm14 ? but i need a semi stable rom... this was working perfect !
Hello, since i have restored the stock rom in my A1, the camera (photo/video) started to open really really slow, only after 30 second of black screen the camera starts.What it can be ? I lost my imei before the stock rom restore, maybe is a problem in eis partition
Install module MI A1 Camera Lag Fix Oreo in magisk.
thank u a lot
These lags refer to different camera API used by Google's camera.
Hello, My phone's (main)camera is not being registered by the stock camera app , neither by Gcam. But it shows up in apps like instagram and snapchat and works just fine, no crashes or such. I tried resetting my phone through settings and the ****ty bootloader you get with a locked H870DS (un rootable) model and it didn't seem to work.
What I am thinking is, there's something wrong with the camera ID allocations of the camera but still confused as to why even after resetting, it won't work. Any way that I can erase the system and other partitions and do a fresh stock os installation? UGH it was so easy with root. Lg made a great device ****ty by locking it down for me.
Update: So I forgot to add how I came to the conclusion of camera ID being allocated wrongly. When I try to open the stock camera app by long pressing and selecting 'Selfie cam' , it opens up the wide angle rear camera. Either the front cam is done for or my device is.
So everyone's in quarintine but no one wants to help?
Hey,
today i tried to recreate your problem, and i got your problem.
Problem came when i flashed Pixel Experience Android 10 ROM against branded stock Android 9 (branded by Polish Play).
How to solve it? After many trial and errors, problem dissapeared when i flashed stock Android 8 (branded by Polish Play in my case), and did FOTA update.
I hope i helped.
