Export/import PGN of games from Droidfish. 
Import my games to Chess.com 

I found an option to export my games from Chess.com (Share PGN) but I couldn't find any options for the rest of them.

user4223: Another method for exporting games from DroidFish is:

Enter the game on a new board
Long press the "M", then choose "File", then "Save game to PGN file". Create a new file if you don't have one already
This file can be found on your device's storage under /DroidFish/pgn.  I accessed it with AirDroid but you could use any file manager app or even USB connection.

This will work for multiple games in one file.

You should do the following:
Copy the content of the PGN file into clipboard 

Open your PGN file in your favorite editor (e.g. notepad)
Mark the content of the PGN
Copy the PGN content into the clipboard (e.g. using CTRL + C)
Open chess.com import pgn



Choose Load PGN
Paste the PGN content from clipboard (e.g. using CTRL + V)
Choose Load

Hold down on the board, and a set of options appear:


Click on Share Game or Clipboard to share (export) PGN.
Click on Retrieve Position to import PGN from your device. Alternatively, if you have the game on Clipboard, you can click Clipboard and then choose to paste the game from Clipboard.
