Yeah and a meteor could smash into your house in the next 30 minutes but I wouldn’t count on that either.
The way apps work on android is, they are compartmentalized, if you disable a system app like this, the worst that will happen is some things may get wonky, if you enable it, it will start right back up again.
It’s just a service, if it was something that tracphone wanted to absolutely keep you from disabling, they would have put it in the bootloader. It’s most likely just a marketing app that they get kickbacks for including on their phones
Edit: Here, exactly like I said. My man you got this idea of a worst case scenario in your head with absolutely no evidence
OnePlus “used” to be the unlockable phone, they changed their policy around 9 I believe
