Great a lot of people have been waiting for this will flash and test it out later tonight

Thanks for your work! Great to see more people with the right knowledge with their hands on a Note Pro.

Unfortunately I use the camera daily....I'll keep an eye on this, though, in case that gets worked out.

I'm a retired deveopler and don't mind helping out a little where I can. I've enjoyed tweaking my P900 to the max & I'm also glad to finally see some stuff coming out here on XDA for the P900 wifi version. Not much activity on any other forum for this device either. Most likely because of the price of the device and people worring about the Knox tripping issue. I noticed on another forum that someone had compiled a fully functional kernel however they too were experiencing issues with the camera. Anybody have any ideas of whats causing the camera issue? I can possibly help out with the developement of a AOSP rom, or a blazing fast slimmed down ROM. I have plenty of developement knowledge in this area, if there are any interest for one. As for the Kernel issues I'm not too familiar with the compiling however most likely could figure it out.

Flashed this kernel and my tablet won't boot

? I hope you made a backup of your stock kernel before flashing...

Has anyone else flashed this kernel and can confirm if it is booting or not?

I started from scratch and flashed the tweaked p900 rom and this kernel and now it is working great it seems to be much quicker then what it was I really appreciate your work and it makes this tablet what it should be

Can you describe what happens when you select the "Camera" application. Does it force close, not launch, display some type of error. If you could provide the details of what happens, it may be possible to provide a working solution or "Work around."
Also, try installing another camera application from the Android Market and see if that application works. Maybe using another camera source will work and that could be a temporary work around till the issue us resolved. Let us know. Thanks!

Mine says warning camera failed

Ok, Thanks. We'll see if we can figure this thing out...
Did you try installing another camera app from the play store and see what happens when you launch it?

here's my observations:

1. Samsung Knox does not get removed as claimed in OP
2. Knox FC every time something is installed and uninstalled (likely under different circumstances too)
3. front camera works perfectly fine
4. rear camera does indeed fail
5. Google camera and 3rd party camera apps fail too
6. Z Device Test still detects all the hardware properties of the rear camera (but maybe that info is retrieved from elsewhere in the /system)
7a. all logcat apps do not work. i waited about 3 to 4 minutes for each to load.
7b. I haven't used it on this tab in a long time so I don't know if kernel caused this
7c. yes, I granted SU to the logcat apps, and later verified that SU wasn't denied.

my relevant info:
p900 USA wifi-only 64gb model
P900UEU1ANC5 (XAR)

edit:
to anyone that cannot boot after installing:

1. try wiping cache and dalvik cache
2. re download and try again if above doesn't fix it
3. if above doesn't fix it and you're on NAE, try updating to ANC5 (or newer?) THEN flashing the kernel again
4. if you're on a version newer than ANC5 that might be the problem and you are out of luck until the kernel is updated for it.

don't ask me about how to update, that's your burden

thanks for you post

stock, Google camera, and Z Device Test

edit: flashlight does work for me

edit #2: with stock, you can't get to front camera again after switching to rear, because the app will just close when the rear fails. mine was already on front, then I switched to rear and

i think there is problem with permissions but i can't find where is exactly

 

[Sterist]

i think there is problem with permissions but i can't find where is exactly

probably SElinux

 

[bonuzzz]

probably SElinux

it's permissive
and camera works in stock kernel with selinux permissive.
z device test sees two cameras, so it doesn't kernel problem. back camera and flashlight dont work for me. front camera works fine. i dont have any ideas except permissions

if anyone want to help, this is a kernel without any mods https://yadi.sk/d/-RWbv8htbYW28

ps: replaced link above. logcat is working here

that might be the app not able to turn on this tab's LED

torch apps work

Okay, this has nothing to do with me since I have P905 with stock kernel. I just read this thread by curiosity and though one thing about camera. Can you open test menu anyway on that device which opens on 3G models (and phones) by typing *#0*# to dialer (P900 has no dialer right?) There you can perform some tests to device and one is to check does camera work right.

Hope this helps, or then it wont

p900 doesn't have dialer
z device test detects both cameras..

i now realize why it seems much faster - i am running with interactive and fiops and it is contantly at 2000mhz no lower frequencies are being used - i though it was like this on performance not interactive - obviously the battery is not great right now lol
