[XTREME-UX- KERNEL]- V4 -[UBERTC 6.2 - GCC 6.2.1] - N920 C/G/I/L/S/K-CD - GraceUX - Galaxy Note5 Android Development

About Xtreme Kernel for Samsung Galaxy Note 5
The main goal of this kernel is to target a niche group of people looking for a daily drive kernel for their devices,a solid stable kernel with extended battery life without sacrifying performances, a reliable kernel with the best smoother user experience possible and optimum power efficiency managment.
With those guidelines in mind,i am not going to re-invent the wheel,as samsung and linux devs already did a really great job on android linux kernel, but more a fine tuning on differents kernel's sections that has direct impact on battery life and performances,without affecting their dependencies and inter-dependencies wich may lead to unexpected behaviour (no blind cherry-picking or patch merging,but more reading linux documentation for better understanding)
The challenge was to match the best balanced profil design for performances/battery life with solid stability to bring a different user experience than stock one, wich is not battery friendly,especially on ux firmware, as most of users know its battery drain 'issue'.
Agrressive improvments has been done on this kernel, tracking every bit that can take up precious resources on your phone when you aren’t using it, and improved this even further by making more wise power serving while in use, resulting in a longer battery life wich can last more with extra time.
This kernel doesn't have bells and wisthles other kernels have,if you are looking for playing with voltage, frequencies and synapse so this kernel may not fit your needs and suits your habits,you still are completly free to use it or no,it's up to you.
Xtreme Kernel has been tested and working fine so far,so be more precise when reporting if you encounter any issue to pinpoint the problem for better diagnosis.(FYI kernel has been reported bug free from all testers).
I hope you will enjoy your experience with this kernel,it will get more improvments in futur regarding your feedbacks.
Enjoy !
Important Note:
- Call waiting issue is a known bug on official ux korean firmware,it's not kernel related so ask rom devs for fix or look for it on xda.

- DISCLAIMER
I AM NOT RESPONSIBLE,NOR XDA, FOR ANY BRICK OR HARM THAT MAY OCCUR ON YOUR DEVICE,YOU ARE THE ONLY RESPONSIBLE OF USING ANY FLASHABLE FILES ON YOUR PHONE,BY FLASHING THIS KERNEL, I ASSUME THAT YOU AGREED TO THIS TERM AND YOU ARE DOING IT AT YOUR OWN RISK ! THINK TWICE BEFORE ENGAGING YOUR OWN RESPONSABILTY !
BUT SO FAR, THE KERNEL IS WORKING FINE ON MY SAMSUNG GALAXY NOTE 5 SM-N920C ,AND ALL BETA TESTERS ARE CONFIRMING VIA REPORTED FEEDBACKS THAT THIS KERNEL IS WORKING FINE TOO ON THEIR SAME DEVICE.RE-THINK AGAIN BEFORE FLASHING.

- Steps for flashing kernel:
I assume that you are already on a rooted device with TWRP 3.0.x.x installed,if not,useful posts on how to root and install twrp can be found on Xda,just do a search.
1 - enter recovery mode via twrp
2 - Wipe cache and Dalvick/ART cache ( important step or junk files will lead to internal conflicts like freeze lags or random reboots)
3 - Flash kernel and reboot,(it will bootloop once,just don't touch it and don't panic)
4 - After complete reboot,don't use the phone and let the kernel settle for 5 minutes for better hardware and firmware integration,if u use it while rebuilting cache and integrating,you may experience lags or freeze,so let it install comfortably before starting usage.
5 - after step 4 , you can use the kernel. A second reboot is advicable but not obligatory,it's up to you.
6- Enjoy Xtreme Kernel !

- No uci support ( i'm not a synapse fan,a battery saver profil can be a bit good for battery saving but catastrophic for playing games with hard cpus loads and vice versa ,better to let kernel manage everything,just sit back in the car like a boss to enjoy ride and let the driver manage driving hassles )
- Best Balanced profil optimized for best perfs/battery life
And much more...too long technicals features to be listed.

- Permissive Mode
- How to set SE linux to Permissive permanently for Xtreme Kernel with SELinux Enforcing mode ?
1- You need to have 2 tools:
--- A root files explorer like Fx Explorer with root addon OR Root explorer ( I am using Fx explorer ,personal preference)
--- Universal init.d (to enable support), Download it from PlayStore
2- Once installed,enable it by switching to ON
3- With root access, Go to system/etc/init.d directory
4- Create a file and name it 08setperm
5- Open new created file and write these 2 lines:
#!/system/sh
setenforce 0
6- Save and close
7- Give full permissions (read,write,execute) to the file " 08setperm " like this "rwxrwxrwx" (use Fx Explorer or Root explorer to edit and change permissions)
8- Open Universal init.d and switch to ON and click on "08setperm" then click 'execute' on top (the play buttom).
9- Now Reboot your phone
10- Done! your SELinux mode is set to permissive permanetly.
To revert back to Enforcing, just switch to OFF Universal init.d enabler and reboot .
