I plan on getting a S20 5g (2 sim) set from Shopee to replace my current S10e

Can anyone confirm whether :

1) Does it still get OTA Android and security updates?

2) Does the dual sim function work for other countries like NZ & Australia?

3) Are there any common issues with Imported model?

Thank you all!
