Phone slow after root

[pitbullmommy45245]

I rooted and am running tek s ROM. The phone has been super laggy and slow since I flashed that ROM. Any advice.

Have you switched the governor to interactive or on-demand? That's the most important piece. The below link has a bunch of tips (universal to qualcomm/US S7 and S7e) to improve performance.

Check the thread under Guides about common problems and fixes.

I did but I didn't see a fix for this. I did what another member told me to do and it worked.

Bug #1: Phone is laggy after rooting the phone/Battery is down the tank.

Fix: The phone is (partially) lagging because the ENG bootloader automatically sets the CPU governor to "Performance." While this is supposed to lock the CPU frequency at the maximum values, it does cause a lot of heat and possibly throttling. Additionally, the max core clocks are set to 1.593Ghz instead of their actual maximums. Not every CPU Tuner will allow you to set the big cores separately, so look around for one that does if you don't want to use Kernel Toolkit.

First, use Flashify to flash one of two zips provided by psouza4 on our sister Verizon Galaxy S7 (Edge) threads.
1. Kernel fixes & tweaks V15
2. Kernel fixes, tweaks, & Debloater
You need only flash one of these two zips. One additionally debloats the system, one does not. Choose whichever suits your needs.

Next, install a CPU Tuner utility like Kernel Toolkit, then change the governor from "Performance" to "Interactive." Also change the max CPU frequency of the little cores to 1.593Ghz and the big cores to 2.150Ghz while you're at it. Leave the cores at their default minimum frequency. This will go a long way to improving the speed of the phone. Also make sure you that have the new settings to apply on boot. Every kernel manager should have this option somewhere.
Note: Although the max frequency in the settings screen will drop to some number, as long as you can see the CPU ramp up to the new settings in the information screen, then everything is fine. You can test the max frequency by turning the screen off and then back on.

Then, install sEFix and set entropy to "Ultra."

Lastly, install L Speed and:
Code:
-Main Tweaks: Turn on
-Battery Improvement
-OOM Killer
-Kernel Tweaks - "Light"
-CPU Tuner: Turn on
-CPU Optimizer
-LNET Optimizer: Turn on
-Google DNS
-Faster Streaming
-Faster Dormancy
-IO Tweaks: Turn on
-IO Boost
-Partition Remount
-RAM Manager
-Balanced
-Seeder
-Moderate

Literally the first bug and fix on the guide.
