[Samsung Galaxy S7 (Exynos) ROMs, Kernels, Recoveri] Jdkrosen:
As far as I know from the others postings above me that it's all fine and dandy for them and lag-free; I'm not saying it isn't or is but I'm saying either they didn't notice or it truly is working for them and that it could come down to it being model specific. From what I noticed when I first used the kernel ever (6.7.X somewhere) that the TeamExyKings ROM provided (There being three to choose from at the time because it doesn't offer it now because of said issues people have been having, restarts, lag ect) it lagged at the intro. Choosing languages took a bit, pressing the start prompt and choosing wifi, everything would take a bit. Since it was obviously the kernel I flashed Moro that was available within the ROM and everything loaded lag free through the intro, so I decided to try TGP again. It lagged again. This time I decided to go through the intro completely, maybe it just hasn't had enough time to settle? No improvement. I went into the developer console because I like turning off all animations and when I kept pressing back to go back to the home screen it stopped responding. It froze and then caused a kernel panic which force restarts it (I could be wrong cause this kernel has panic disabled I think) What happened was it started to optimize all the apps and once it was done everything was good. No lag, it was perfect. Never had an issue again (At one point I did get another random freeze opening up the Breath of the Wild map app a few times and it re-optimized only a few apps and everything was perfect again. Probably just a fluke, never had it happen again). So I did another test. I re-flashed my carriers stock firmware (I ALWAYS do this before I update the current custom ROM or kernel to proof it from most issues, I've never dirty flashed and I never will) and I instead wanted to get it to panic at the intro if I could (Because it seems that because of the lag, too much input (For example the capacitive back button) that initially caused it to freeze will cause it to do it again but it can be an app to for sure), so I went as far as skipping the google account entry page (Because if I tried it say a page or 2 after pressing the start prompt, it'll just take me back to the start prompt page again without freezing because it's not processing much to get that far. However if you cause more input for it to process say 5-6 pages in that intro it'll just freeze and restart. You'll notice this when the capacitive keys stop lighting up in response to the tapping of the back key) and pressing the back key until it froze and restarted to optimize all the apps. Everything has worked perfectly every time I've done it that way since I noticed a trend. How do you know if it's not? Like I said if the people above me didn't notice it or it's truly working for them, you should notice the difference between if it's smooth and speedy working or it's still lagging even after doing what I did. Maybe it's just me but I've done it multiple times on 6.7.2 & 6.8.0 but everything above 6.8.0 continues to lag with no improvement from my method so now I can tell if it's working or not. There's a rare occurrence where it'll freeze but not do anything and stay frozen so at that point you'll have to force restart it but so far that's only happened on the kernels that I've tested not to be working properly.
