[AT&T Samsung Galaxy S7 Edge ROMs, Kernels, Recover] Matthenson20:
Ok guys, here we go, been running most of these settings for a few weeks now without much issue so I'm gonna share everything I did and the tweaks I made through different apps

I will also try to remember to post links and which apps to use but if i forget forgive me

A- Install process

B-Titanium app freeze

C- Kernel Auditor Tweaks ( and some explanation)

D- Echoe Mod Tweaks

E- Anything else I do and BUGS

A-Installation

1. Installed U Firmware my ATT s7 Edge using this method https://xdaforums.com/att-s7-edge/how-to/updated-935u-935a-live-links-pi3-t3501686

2. Rooted u Firmware using this method https://xdaforums.com/att-s7-edge/how-to/root-available-t3411650

3. Installed ECHOE ROM and allowed it to fully boot, made no settings, installed no apps

4. Using Flashfire, I wiped dalvik and cache, installed the s7 fix zip http://dl.psouza4.com/android/S7_or_S7Edge_Fixes_V15.zip

5. Reboot, allow it to settle, and finish setting everything up for how you want to use, there is no wiping after this portion

B. Titanium Freeze

Freeze what you don't use when it comes to Samsung apps, I don't use GEARVR or Samsung Pay so I froze most of the related apps.

C. Kernel Auditor Tweaks

I switched both governors to INTERACTIVE, seems to have a good balance between battery life and little lag ( I get an honest 4 hrs screen on time everyday, but I'm a heavy Youtube user and I constantly have to check/send emails)

I did however spend a week running PERFORMANCE, had absolutely no lag, and believe it or not my overall battery life (when paired with force doze) wasn't bad, still got 3 hrs screen on time that way.

I only tune the BIG set of core, here are those tweaks

D. ECHOE Rom Controls

I do Have Viper enabled

I do have faster GPS enabled

I do run AdAway

I do Run Force Doze

Settings- Dont Disable Sensors on Screen Off

Turn off While Charging is on

Ignore Lockscreen Timeout is on

Disable Motion sensing for Doze is on

I don't use the volume control or icon apps but keep them enabled

E. ANYTHING ELSE

I nuked a lot of location settings, made sure I turned my google tracking off etc etc, screen stays halfway bright or brighter, i use wifi when available, I enabled developer mode and disabled all the animations(I swear this changed the lag better then anything else lol)

I don't run any widgets except a clock and weather, and the only social app I use is Twitter, and it doesn't update unless I receive a mention or I open it myself

I also run a black theme with Holo blue colors to help on AMOLED juice consumption

I also found these settings eliminated my camera lag when filming in 4k or using the 60 fps cam, but I also changed my camera storage to internal memory to help with that issue as well

I occasionally get lag when using my car charger, and occasionally my phone will reboot when I charge it, and I also reboot and wipe all my caches weekly

HOPE THIS HELPS!!!!!
