TigerTweaks 4.0

Step 1 - Configuring FDE.AI

- Uninstall ANY OTHER KERNEL MANAGER app including smartpack/Ktweaks to avoid conflict, since this app uses AI and machine learning to dynamically boost performance when needed

- Install FDE AI Magisk Module to make it a system app, thus it will work better and removes all kernel locks from OEMs (I'm looking at you, Samsung) https://github.com/feravolt/FDE.AI-docs/releases/download/12.4.1m/FDE.AI-as-system-app.MAGISK.zip

- Update FDE AI to the latest version by downloading the latest APK here, since the fde ai magisk module will only install fde ai 12.4.1, not the latest version: https://github.com/feravolt/FDE.AI-docs/releases

Step 2 - Ask AI to optimize your system!

- Move to the bottom of the screen and select AI Chat, then type /advancedai (no space, no uppercase letters). This will going to make the AI more effective, without you having to do anything.

- Then, type /extraopt everything and /extraopt. This will optimize your system as best as possible for maximum performance and power saving, and it has a BIG, BIG performance effect, and battery would last longer too.

- Type /extraopt auto. This will optimize your system every 5 AM in the morning. Make sure device is charging and screen is off everytime you sleep!

- Go to the settings tab and use the AUTO settings for FDE AI.

Why not performance? Why not powersave?

Well, by setting the FDE to stick to max performance or power savings at all times, youre missing out the one key advantage that FDE has. Which, the AI can shift between performance and power savings (or even in between depending on the load) in real time. If your phone is on idle, FDE would go into Automatic/Power Saving mode, and if you're playing your favourite game or is doing a heavy task, FDE would go into Automatic/Performance mode. So, you will get performance ONLY when you need it. If your phone is on idle, it would switch fde to powersave, thus saving a ton of battery life!

- Tap on boost heavy games, force doze, and disable throttling.

NOTE: Only disable throttling on NON OC KERNELS! Disabling throttling in OC KERNELS can lead to overheating!

- Good features to keep in mind:

1. /gamelistadd package name

You can add your own heavy game here! For example, if you play war robots, go look at the package name for War Robots, and then enter the package name (for war robots it's com.pixonic.wwr) because your game might not be listed on the heavy games list! Though this is not strictly necessary as FDE AI can detect if you're under heavy GPU/CPU load while playing games, so FDE can adjust to Automatic/Performance which will boost your game, even if it's not included in the heavy games list.

2. /downscale

You can downscale your resolution without having to adjust fiddly DPI settings! The AI would work on everything for you to scale it adaptively, so no risk of soft bricking!

For example:

Downscale 540 for 540p (qHD)

Downscale 720 for 720p (HD)

Downscale 1080 for 1080p (FHD)

Downscale 1440 for 1440p (QHD)

Downscale 2160 for 2160p (4K)

Step 3

- Install GMS doze magisk module. Helps to reduce power consumption of google play services which will increase performance and extend battery life.

Recommended Custom Kernel

Gcam: https://www.celsoazevedo.com/files/android/google-camera/dev-bsg/f/dl61/

apply this config https://www.celsoazevedo.com/files/android/p/f/2021/11/BSG-A71-GV1h.xml

and this LIB https://f.celsoazevedo.com/file/cfiles/gcm1/morgenmanlibv6.so

Get fast charging

to install download from https://drive.google.com/file/d/1KguCeLD-VHShm0MYzKhYrsAv-rZAuJeA/view?usp=sharing

Follow the instructions, and then select 4500ma and 27w. This would make your device charge faster
