Front camera not working on CM 13 bootloader ROMs.

As in the topic. Rear camera is working OK, but front is like not detected. I provided full wipe and it didn't work. On MIUI it's working OK. FP, data and other bugs that other people gets on CM 13 don't meet me. Only the front camera.
Any guide or smbd with similiar problem? Thanks.

... but I thought that nobody except me has this problem and there's solution for it.

Can't make two patches work simultaneously !!

I have Redmi Note 3(SD) 32Gigs.
So i have this whole new kinda problem.....i want to use custom nougat roms but there was this problem that arose everytime i installed them is that there was no option for switching to my rear camera in any camera app. So i installed the Agni N Kernel 's camera lib patch which required a custom kernel to work(Radon in my case), and then the camera was working like a charm.
But also i have Goodix fingerprint sensor, so i have to use a patch for them too to make them work in these roms.
So the problem is
This Camera fix works perfectly fine, but this seems to disable my fingerprint sensor.
And when i make the fingerprint work(by patching the file again), the camera gets back to what it was earlier, i mean without the rear camera option.
These both features are not working at the same time for me.
Please help me with this :crying:
Thanks in advance

Xiaomi Redmi Note 4X OmniVision Camera

We discover that there is third camera sensor for Redmi Note 4X its the OV13855 OmniVision sensor.
I want to make a request to the all users whit higher level than my to port the driver camera and make a fix for the users like me to enjo to the all roms avaible in Xda.
Here some info that i found in Miui forum -> http://en.miui.com/thread-519415-11-1.html (last commnet in page 11)
Thats the problem wen flash some Rom the back camera to not work.
So if your back camera dont work start asking for fix.
Yep,I've met this situation,My back camera is OV13855,and any other users flashed thirdpart ROMs can use their back camera as normal.At first The XDA ROM publishers don't notice this camera drivers' thing,I also tried another roms like AXE,RR,Unofficial Los,and any other 3rdpart camera apps,absolutly,the back camera is not woking...Maybe developers will update new driver for OV Ver.Camera?Or just wait for XiaoMi CO. to open sourse?

Poco f1 flashlight and 12 mp camera not working

I have a poco f1 in which flashlight is not working nd even 12 mp camera not working. tried switching many roms aosp and miui but still not working.I also flashed miui stock rom through fastboot mode but no luck. can anyone help me in this problem. + flashlight is working in Cit mode.flashlight button is greyed out
I have the same problem, did you find any solution
I think the Persist partition might have got corrupted. I know that for a similar issue for a different device this was the solution.
Edit: The fix involved in that case was to flash the persist partition image.
