An export world button for mobile players

It is genuinely hard for us mobile players to Export and Import our own worlds now that mobile phones had advanced, I used to have an old phone, so i can still access in my files to move my own world to my PC, mainly because i Prefer playing in Mobile, But since I have a new phone, i cannot even move my own files anymore which made it very difficult for me to move files and I'm forced to just play in my pc instead, I'm sure that some mobile players are having the same problem which is very sad that they can lose their own worlds mainly because of the strictness within the new phones these days, I don't wanna lose my beloved world so it will be very appreciated if an export button will be provided within mobile players. I hope this makes sense, Thank you.
