Code:
[B][SIZE="3"]Your warranty is now void.
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed. Please
do some research if you have any concerns about features included in this KERNEL
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.
Please read completely this thread before using for minimize FAQ.

F.A.Q

[COLOR="#34D1GE"]Frequently Asked Questions[/COLOR]
1. What ROMs are compatible?
> All pie & 10 ROMS.
2. Is it EAS or HMP?
> The normal NotKernel is HMP & Notkernel-Lite is EAS.
3. F2FS supported?
> Yes
4. My camera is not working
> There are two builds one with old camera driver and one with new so flash according to your ROM..
5. Notkernel has ___ bug || ___ doesn't work properly on Notkernel
> Bugs and issues are common in custom kernels. We are by no means pro's at the job and may mess things up at times. But we do let the kernel go through a bunch of testing by the members of our Testers' group, so the chances of major bugs existing in the release builds is comparitively low. However if you do end up facing bugs, please do report it through our support group or messaging me on Telegram[Yasirsiddiqui]. Even if you are not in a state to give any logs or detailed description, at least mentioning it to us briefly would help us a lot.
