It is like exploring the world by leaving your Home. You can reach your phone limit, But If you are not careful, there will be some issues that can happen to your phone. You are limited by your Software If you use Official Manufacturer Firmware. But, After rooting, you can use Custom ROMs. If you notice 3 or 4-Year-Old device can use Pie 9.0 Lineage version. Where your manufacturer Don’t release updates.

I hope it will happen soon as I’m starting to think that the one I bought is fake since all I have found on the internet are FN and mine is GN.
No. Your model is not fake. Samsung always attaches the extension in the model numbers to identify the region. GN models are Philippines based. You can try Magisk patched method now. You can Flash TWRP After it released.
