### Quick Tips

- **Use Obtainium** to manage updates of apps from GitHub directly.
- Apps marked with **(root/Shizuku)** need advanced access — only use if you know what you’re doing.
- Combine **Droid-ify** or **Aurora Store** for browsing and downloading apps not on Play Store.

* * *

### Important Notes

- Always verify app authenticity via GitHub or F-Droid. Avoid shady APK sites.
- Some apps offer **optional paid versions** , but their base functionality remains fully FOSS.
- While most apps don’t require root, **certain features (like debloating or battery tweaking)** may.
- Some apps like **Fennec** may lag behind upstream Firefox — check changelogs before switching.
