My phone is Samsung Galaxy J7. Internal Memory is full and I want to move this large pp to SD. How can I do so?
It is NOT recommended by the AnkiDroid team. Here is the Github issue about this: https://github.com/ankidroid/Anki-Android/issues/3106
Someone reported success using the procedure below, please make backups and remember that you are on your own if you choose to do it.
Go to your external SD card folder via file management app and create a folder with the apk's package name ("com.ichi2.anki") containing an AnkiDroid sub-folder: the exact path depends on your devices. E.g.

Install AnkiDroid, open it, and change the storage path to the path I mentioned above.
