Try going to game files using computer i think there will be a "saves" folder

I don't know if it's possible or not. You could ask in #help on the Mindustry discord server here: https://discord.gg/mindustry

The newest release (92) allows you to export progress as a zip file by going into Settings->Game Data. You can transfer this file between devices to import their data.

You haved to manually do it. You haved to move the save file from your old phone to your new phone just copy and paste the "saves" folder.
