Samsung & Android features

Have any of you guys used Samsung Quickshare? To send files & photos (fullrez). Its very fast, similar to Airdrop.

I've heard that Google is collaborating to bring it to mainstream Android and also with Windows to transfer to PCs.

Also, Samsung has some unique features where you can play audio simultaneously with 2 Bluetooth connections. Very handy when watching videos or podcasts with someone. (Realme had the same in Labs, but never used)
