Bixby should be listened my voice even if my fone is locked like to speak time

Give an option of document scan in samsung notes app so that documents can be scanned and saved as pdf file directly it's very important. This app needs improvement. Everytime I scan documents and make pdf I have to use third party app

If I'm talking to someone on sim1 can I get call waiting on sim2

I want to use wifi and Hotspot at same time

Make Bixby more advanced so that I don't need to touch my fone for answering calls and also using earbuds no need to take out phone from my pocket.
