Root gives me more control over my device and many powerful apps like shizuku and sdmaid works better than non root. Usually i don't use magisk modules. And one another use is it installs app updates without a waring like play store. That's it.
Google app and the play services still present on your device, which means it feeds data into gemini in a direct or indirect way. If you need privacy from gemini then you must degoogle. Convenience and privacy won't fit in one basket.
Why don't try lineage os without microg which is way better for privacy and security!
Am living in india and it seems cape have no service in india.
