This is what I did:
Before we begin, disable Google Play services and Google Play store to reduce conflict with app on F-Droid.
Decentralization gets us even further with what I figured out.
Install F-Droid.apk and verify with GPG && install F-Droid.
Update F-Droid repository and search for Termux.
Install Termux. Open termux and type setup-termux-storage
Grant Termux access to storage.
Do the following commands:
pkg install update
pkg install upgrade
pkg install openssl
pkg install openssh
pkg install proot
pkg install bitcoin
cd
Optional: if you want to copy your bitcoin folder from your pruned bitcoin (I have 2200mb prune) server or computer and prune it, fine (location: cd .bitcoin)
bitcoind -prune=2200
Recommended: On Termux notification on Android, enable
acquire wakelock and disable battery optimisation for Termux. Also, in router virtual server/port forwarding, Enable TCP port 8333 to 8333 for yur phone's ip address.
Note: during initial sync, it can cause silicon degradation so it is recommended to get a recent (within 3 months of blocks) pruned and try on your pc first (linux) before copying blockchain files to .bitcoin folder in termux. As long as you keep blockchain within 3 months, your phone is not stressed. Let's decentralise BTC more! :)

Am I doing it right?
