Adaway of course, and wireguard via the proper kernel module.

I use:

• Material Files - Root file explorer FOSS and no ads

• Termux - Terminal emulator

• GAppsMod - enable call recording in United States

• ReVanced Manager - Spiritual successor of YouTube vanced, works for more than just YouTube

• Substratum - theme engine, needs to be combined with a theme pack and most are not free

• Swift Backup - backs up app data, calls, messages, etc to cloud. Can set it to use WebDAV, SMB, SFTP, S3, etc. Can also back up locally

XPosed / LSPosed

• Dark eyes tricks - general system mods, mostly use it for "Power key to toggle torch"

• Snap Enhance - if you need Snapchat to communicate with half of you friends you can nuke most ads, get download options, screenshot without sending a message, view chats without marking them as read, enable dark mode, and others I don't use

• XPosed Edge Pro - let's you bind actions to triggers. I use it to get a Samsung like app drawer from the side of my screen, but you can bind keys, gestures, schedules, app states, just overall useful

Magisk Modules

• AOSP Mods -let's you configure a bunch of stuff in near vanilla roms

• Universal SafetyNet Fix - V2.4.0-MOD_1.2, allows banking and Google pay to work, as well as any app that blocks root. Add to magisk deny list

I'm using these:

• App Manager
• SmartPack-Kernel Manager
• Ghost Commander

• Minminguard as ad blocker (used with Magisk and lsposed)
• Titanium Backup for real backups.

File manager: Material Files, on a rooted phone it can access files outside of /storage/emulated/0

Terminal: Termux
