If you have root access it isn't a problem, then you can use alternatives, like GrapheneOS, Ubuntu Touch, CalyxOS or similar. The only problem is if you need an official app, since they are usually only available for Android or iOS. Then the only are Replicant or LinageOS, these are "degoogled" Android forks

If it wasn't for locked devices and proprietary drivers, it would be a nice experience, very close to linux.
