Flash Agat or KT Kernel (4.3 version obviously) and there ya go!
WiFi works but it says it has an unstable connection and often stops working but stays connected
ith all the 4.3 roms my work wifi will not connect. Home it does. At work it does need a username and password to get on while home its just a key password. Is it a kernel issue since I have not seen a stock one for mja? I did install mja modem etc minus bootloader

Find a different compatible kernel for your specific phone and flash it.
Most likely it will fix your wifi issue.
I think flashing the appropriate modem (xxuemj7) will fix the problem since this happens beacuse of the modem.

Auto Rotate problem

I was with Kitkat German, and suddenly - when I tried to rotate the screen, he also turns around, but he did not turn around right .. and the camera takes pictures upside down, even when I went back to -4.2.2 same thing and not solved ..
Access Warranty?
UP
It's the kitkat modem that messes up the auto-rotate and some other things, have you tried downgrading the modem if possible? Download a flashable zip for the previous modem and flash it via recovery.
Link please for old modem?
thanks.
I'm currently having the same problem. The old modems are not working.

I installed the old modem and now the screen does not turn around at all.
You need a Kitkat baseband for a Kitkat ROM!
Some folks reported that recalibrating the gyro helps.

I can't recalibrate it. The settings app force closes if I try too.

I would prefer flashing the rom new and to not mess up with different basebands.

'K bro let me figure out what's the situation. Tell me how & when exactly did this happen. After you flashed a new rom or some update or something. Also which rom and all you've flashed in the past before and after wifi issues started????
Sent from my SM-G800H using Tapatalk
Actually I can't tell cause I got it used, it was with stock official 4.4.2
It worked sometimes, most of time not, or just gave a fake WiFi Signal..like it says it's connected, but actually no Internet.
So I Flashed another stock official rom via Odin, got same results, then I tried flashing some fixes I found around the Internet, the ones you put in PDA and flash, it worked for sometime then stopped..
Rooted and tried deleting efs, no luck.
Lastly I Flashed 4 Files factory ROM 4.4.2 with its pit file.. It didn't work.
Of course I've tried it on other routers..
So no matter what I do it stays on "Saved, Secure"
It's really weird thing as Bluetooth and Hotspot are both working..

Don't get me wrong but in your first post you said "different stock ROMs" later you said "another official stock ROM", dude as far as I know there's only one stock ROM for every device, it may have different Android versions like 4.3 or 4.4

Okay so let me tell you what happened with me was something similar issue.
I flashed the GeNxt N4 rom and after that it is instructed to flash Deds kernel but cwm is buggy and it behaves weirdly so you cannot return to recovery to flash kernel and rom withing the same boot into recovery without reboot.
So i changed roms but to my surprise i had wifi issues in all of 'em. So i used philz recovery and flashed N4 rom with the Deds kernel and finally fixed.
So maybe yours the same case. The previous owner did something similar and wifi issue could'nt fix so he gave to you.

Here's the link for everything you need to know. Just use philz instead of cwm.

Thanks friend, I'll try it.
But is it mandatory to do it over (4.4.4 base rom ie gennxt n4) or directly on stock 4.4.2 would be fine?
Thanks in advance.

Do on Gennxt. Cuz what i think is the problem is previously this rom was maybe flashed on your device without Deds kernel as you say someone else used it before and the bug is showing up on every rom since it was not fixed.
Again i am just trying to guess what the problem is. Hope it helps

Maybe 3rd party wifi apps could help. Try WPS connect app.
