Saving Notes when I change an Android phone I have a Xiaomi MI3 and I'll buy the new Xiaomi MI6. In my current phone I have many notes (about 150 notes that I have to save).

Is there a way to save notes in order to have them in the next phone? Because I dont'know how to save them using the google account or the Mi account.
Are you using some specific note taking app (i.e., google keep, color note)? If yes, these app has exporting options inbuilt, check out.
