Bootloader unlocked for sure. I really like having control over the updates myself. Haven't done a custom ROM in years. Just recently started going without root since I've found a way around everything I needed root for.
- backup - every app I need backup for is included in the stock Google backup.
- custom kernel that I make for myself. Create what I want built in so no root necessary.
- ad blocking - wireguard server: vpn>pihole>mullvad.
