FAQ:

Q: How to flash kernel?

A: Download (download link in first post) and flash the zip file from TWRP Recovery. Wiping dalvik cache and cache when coming from other kernels is highly recommended.

Q: Phone is stuck with a black screen after I wiped dalvik cache and/or cache. After I waited a while it just rebooted. Is that a bug?

A: This is not a bug it's actually a feature. This is normal because the kernel startup script checks the dalvik cache to be created correctly. If it wasn't created correctly it checks again after 1 min, just to be sure, this is why you have a black screen. Don't force reboot, just wait! If Dalvik cache isn't still created correctly after 1 min, it will reboot and create Dalvik again, it will keep doing this until everything is ok. This can happen even 3 times upon boot. If more than 3 reboots happen then you have a ROM issue.

Q: How to configure the Kernel?

A: Easy way is with Spectrum app from Google Play Store. Synapse for more advanced users. Init.d scripts or Terminal/SManager or similar apps, for experts.

Q: I have issues with notifications, slow notifications while screen is off?

A: Disable battery app optimization for Google Play Services.

Q: YouTube videos are not playing, why? / Why am I getting random reboots (if using 99killer script)?

A: Remove the /system/etc/init.d/99killer script and reboot.

Q: Why not start with version 1.0 ?!

A: Because versions 1.0-1.3 were not released to the public and were tested in private by a group of dedicated people.

Q: I had a freeze/random reboot after I changed settings in Synapse, what can be the cause?

A: It can be a lot of things, but mostly an incompatibility in your chosen settings, if it's kernel related at all. The most known common things that are the cause of this can be Exynos-CPU-hotpluger (disable it), LMK parameters for Oreo version only (reset to defaults) or Doze settings (use stock). If any of these doesn't get rid of the reboots try resetting Synapse and wipe cache and dalvik cache. You can always post logs or details of your issue, to get help.

Q: After each boot i get my screen locked after a brief moment of using my phone and my phone vibrates 3 times, is this a bug?

A: This isn't a bug. The locking of the screen it's a workaround i added, to eliminate a bug where GPU utilization get's stuck. This will remain until i find a better way to solve this. There 3 vibrations is from the PK boot script telling you it has finished execution.

Q: Bixbi button remapper isn't working with Bixby button, how can I fix it?

A: Install Synapse and enable Android logging. (Thanks to [MENTION=7057013]AiRMaX-360[/MENTION] for finding this fix).

Q: What is KernelSU - superuser module and how to get root access without Magisk?

A: Here you can find KernelSU project. This module can be used if root access is needed without Magisk. To get root access you need to create an empty file into /sdcard/Phantom-Kernel/ folder with the name "PK.su" and reboot. Remove the file and reboot to revoke root access.

PS:

* NOT all apps will work with it.

** This also has no app that control access so don't leave it always enabled!

*** If Magisk or other su is found, then that root access method will be used.
