Maybe a few of you have recognized that Screen Mirroring is not working on modified Samsung stock roms when you are rooted, or have an otherwise "modified system" status.
This is due to a restriction of Samsung, which is coded into the file /system/lib/libWFD_ENGINE.so
There are a few threads regarding this, unfortunately I did not find a patched file for our Note3 on the latest 4.4.2 stock roms...
See here for reference:
http://forum.xda-developers.com/showthread.php?t=2556527
http://forum.xda-developers.com/showthread.php?t=2421642
So there have been successful attempts to port this for some devices as you can see here:
http://forum.xda-developers.com/showthread.php?t=2542509
A guide how to do it is for example here:
http://forum.xda-developers.com/showthread.php?t=2551086
Does someone of you have already a patched libWFD_ENGINE.so?
If not, I will try to do it for myself and share it here, but I would prefer if a more experienced developer could do this, it would do us a big favor!
Regards,
Markus
UPDATE:
edit: tried to start for myself, but there is no such file existing on latest stock 4.4.2...
this is not good, as this would mean that this attempt would not work!
does anyone know in which file the restriction is now?
UPDATE 15.07.2014:
here seems to be a proper solution:

there would be no simple answer,
either someone has already patched the file and would like to share,
or we would have to try for ourselves to patch the file according to the
existing posts...

yes, status change and root cloak do not do the trick!
so there must be again some coding which prevents us (rooted users) from using screen mirroring on 4.4.2!
what wonders me:
why does this not bother more users? for me this is a major flaw, because i want to use screen mirroring AND of course root!
so please, if anybody has an idea please let us know!
It has nothing to do with root... cause on the stock kernel and 4.4.2 screen mirroring works... also with root

I just thought it didn't support screen mirroring to the devices I have (Apple TV, Chromecast). I have All cast installed. Should I be able to mirror my screen?
Sent from my SM-N900T using Tapatalk
i also have the same problem with screen mirroring. with 4.3 it works perfect, but with 4.4 it is not possible.
i used the original firmware including root, or different custom firmwares. it connects for 1 second and abort after this.
also i used the stock kernel, that changes nothing.
it is possible to connect to chromcast or also DLNA Mode, but miracast on an wifi stick ist not working.
hope this will be possible, because it is also a main feature for me.
On a Samsung smart TV it works flawlessly with stock kernel

Screen Mirroring does not support Custom Kernels, ONLY Stock Kernels.

even i change Stock Kernels.....still not work
I see no valid reason why it should not support.... the fix specified in the title of the thread could work on 4.3 i did not have the chance to try and it did work on other phones like galaxy s4, its simply a process or something that is denying the connection...
What i did is, i super wiped my phone to factory default and wipe scripts and i flashed stock rom, kernel and recovery 4.4.2 on my SM-N900, since i own a rather expensive new Samsung smart TV i wanted the "privilege" to at least see the feature before i decide if i can live without it....
Setting aside for a moment my bilnd anger for paying top dollar for top of the range appliances by samsung only to loose many features when trying to have the phone suit my needs far far better then sammy did OOB.
So i Flashed the stock.. everything and i finally got it to work after being rooted...
I am now rooted once more and even though i still want the function to work rooted (because perhaps then it can be tweaked to work better then close to crap)
i can say that it aint a big miss in its current state.. in the basic function the image is delayed by about avg of 400 ms making games unplayable. perhaps closing any other source of wi-fi (since it connects through wifi direct if im not mistaking) can push it to 300 ms delay to 250ms but nothing lower, adding to that a small delay in input from a sixaxis controller and you surely cannot play a game of any kind exept if you want unmerited added challenge or simply love frustration... as for browsing or any other function, its nice but if you have a smart tv its quit useless.
i cannot fathom why Airplay mirroring works so well and i mean very very well.. once you figure out how to optimize it on the network.. there are moments that its flawless (even more on the apps that have the same function such as airserver and reflector) My HTC one also will not connect to the TV via miracast even though i know it can, i did not delve in to the issue since i have the HTC Media Link H200 HD. which also connects through p2p wifi of sort.... and works again almost as good as airplay but more hiccups. i havent tried any other dongle yet but i love the concept of the feature and think that we are headed to screen mirroring being heavily used in coming times.
but from what i tested allshare cast with SM-n900 to smart tv (samsung series 8) works very poorly, i am still searching the web and codes and info to try and understand why because i would love to get it working and maybe even tweaked.
and BTW Samsung Smartview app that is used as a tv remote that allows you to watch the tv and control it from your phone remotely does not work when custom code is used..
P.S
when i got it working. i changed back 1 thing at a time. first custom recovery.... then tried after that root... then tried and so on....
once i flashed the custom recovery, still did nothing with it and only flashed the recovery image even without entering it.. broke the function
Any update?
Not connected with routing, but since 4.4.2 I had two issues:-
1) It would try to connect and then just give up. To fix this I held the Dongle-12345 link down until it says "Connect with pin". This allowed me to connect but lead to problem 2
2) All I got was a blank screen. it seems to make the AllShare Cast Hub go into 1080p/30 !! This is an unusual (but valid) mode that not all TVs support. On my Panasonic TV I get a blank screen but on another TV it works. It seems to totally disregard the TV capability with LF21 or LJ02 firmware and I cannot try anything newer because the firmware updater has been withdrawn by Samsung
Not very impressed!

I have a rooted Samsung Galaxy Note 4 (SM-N910F). I often clear running apps to clear RAM, I don't have an SD card installed currently (thought it doesn't seem to make any difference either way) my phone will have a short second or so delay regularly. It happens in all apps I use so I can't narrow it down to one app. This is my first Android device so I'd appreciate any help. Thanks
I had that till I upgraded to the latest supersu

hi,
If you are rooted, have you installed Xposed Framework, and other modules, perhaps?
It is known that Xposed, when installed, it could cause, quite a bit of lag at times, (until you apply relevant fix?) Good luck
Hello, I do have Xposed framework installed. With three modules (see screenshot). I don't Adfree is the only app I have downloaded outside of Google play. I'll perhaps try removing each module to see if that helps.

It's the Xposed framework itself that's causing lag. You need to download a module called XSecureStorage, enable it, clear data for S Health (even if you're not using it) and reboot.

Hi
I am using Samsung Galaxy S5 SM-G900F. I recently updated my phone to Lollipop . Until the update the freedom app was working good in my mobile and after the update to Lollipop Freedom is not opening at all and it force closes. I have even tried flashing Custom Rom ( Cynogen Mod 12 ) and still freedom app force closes.
what is the reason ? Is it because Google has blocked such Third party apps in Lollipop or something i should with my phone .. ?
Any Ideas ? Thanks in Advance.

This happened to me too after a while. Some people say to clear the cameras storage/cach, but this didn't work for me.
Here's what worked for me:
- Disable moto camera app

I switched to the Pixel Experience rom, that fixed my camera issue.

Did you root with SuperSU? That always gave me camera problems. Switched to Magisk and haven't had a problem

Thanks for the recomendation! i flashed the pixel rom and am very happy with it. it fixed the camera issue i was having and its an 8.1 which is leaps and bounds ahead. my previous phone had a locked bootloader from at&t so it was permantly stuck on 4.3.1 i could not flash it at all.
I just got a Galaxy J5 2015 for free from my friend.
This has to be a first Samsung device I'll be using.
So how do I unlock the bootloader?:silly:

Just go to settings then go to information (where include Android version and built number.then click on build number about 7 or 8 times then at your settings the developer option will be show.then tick your usb debugging and OEM LOCK to active them.

Well you have to watch videos on YouTube to prevent brick your phone!
For twrp installing:use the latest version of twrp and don't forget that untick auto restart at odin
When it passed on odin unplug your phone from pc anf get out your battery and after 5sec put it in.and try to go to twrp by volume up+home+power
Good luck

Unlocking bootloader is just a option that you can install custom rom without any issue
BTW:where you got that error?

The problem occurred after unlocking. And the toast notification showed, "Unable to open camera, camera is being used by another application". (Sorry I couldn't grab an screenshot. I thought it was hardware side problem but I checked it. Even if was the rare camera issue then the front camera should work. The flashlight isn't working too,)
I forgot to backup the stock ROM and lost it on ROM installation but after installing ROMs, same issue. I tried 3 ROMs, A8 Port, LineageOS 16 and currently on EvoX.
Tried different camera apps , tried WhatsApp camera also, no luck..
Even CPU-Z isn't recognising the Camera.
The device model is J53gxx.
I flashed TWRP exactly as you said.

My advice would be flash stock ROM through Odin and start all over again.
Boot stock rom and make sure camera and flashlight works, then enable oem unlocking and USB debugging and install twrp and a new rom.
If that doesn't solve the issue then it may be hardware related.
Also you could get a log of trying to open camera app and post it here.
