[Galaxy Note 4 Android Development (Snapdragon)] edeasknight:
Best ROM ever!! - but some lag

First of all, I want to thank you and anyone who works on this gem. Seriously, still seeing releases to this day is awesome and I bought a backup Note4 as this ROM basically extend the Note 4's life when it comes to being a solid , reliable and relevant phone. Not kidding, my girlfriend has a bloatware-filled S8 and when testing downloading and installing an app from the play store and launching various apps/tasks etc we are pretty much on par. THIS IS CRAZY!! Thanks!

That being said, I have a W8 variant and the problem with the early releases (either ripee's or _mone's) was that the camera would not take video at all - but everything else was great and very snappy. As the camera bug got fixed, everything else still worked but I experience some minor yet annoying lags - what I suspect are CPU spikes for a split second. Basically I would navigate the phone, or type for a few seconds, then the UI would hang for a second, and then type all it I had typed while the screen was unresponsive. So it does register what happens. If music plays - even via bluetooth, it doesn't stop for that time. It really seems to only affect the UI (including touch).

I have tried ALL the releases up to 2018-09-06 and the two things I have attempted are :

1) Tweak kernel audiotor. It's really hit or miss but I never get passed the problem completely. As much as I've been playing with custom roms for years, this is my first experience tweaking the kernel and troubleshooting such a problem so if the solution lies in kernel tweaking I would *really* appreciate suggestions. I have read the article on XDA that describes most of them, and have tried the performance one with not much results. After reading more I settled for smartmax. I have also tried disabling MPDecision and using AutoSMP instead. I have also tried forcing all 4 cores by using the options to force input boost frequency at the bottom of the CPU page for all 4 cores - not sure if that makes sense. Considering smartmax governor uses touch poke, I thought that could be a mix of settings that would make things better. I have disabled the version that comes built-in and tried the one from the play store and F-Droid as well and some people claimed that could be the issue.

2) I have also tried going frankenstein. What I mean is that I started with a very early release of the ROM that and the camera bug but no lag. Flashed it, then flashed over a most recent version that had the lag problem over it. I have tried with 2 random versions so far and this is the way I've had the best results so far.

In all instances I did a clean wipe of everything (except micro sd card and usb storage) and flashed. I do use Magisk but do test for the issue on first boot before installing anything at all.

Any help is welcome. I really did a lot of searching on this thread and the RR one as well. I really hope I just didn't see what I was looking for all along. If so I apologize. I'm also open to do any kind of testing with my phone - again it's a W8 variant but if I am not mistaken it is the same as the T variant (Tmobile one) without the WiFi calling. If anyone can confirm that as well I would be grateful.

Thanks so much

EDIT: One more thought, is there any system log I could look at that could potentially point out what hangs the UI?
