This is usually caused by an AnkiDroid bug, but can happen for other reasons as well. To fix the problem, please click the Cards button while adding a card, select the card type you're having trouble with via the tabs at the top, and ensure Options>Deck Override (More>Deck Override on Anki 2.0) is turned off.

Permission Problems

Anki stores your cards' sound and image files on your computer, in your Anki folder, in User 1/collection.media. If you delete any files from that folder, Anki notes they have been removed and on the next sync it will remove them from your other devices as well. What sometimes happens is users tidy up files on their computer, and accidentally remove the sounds and images that their cards use, resulting in sounds not playing or images not appearing. This is particularly easy to do accidentally on a Mac with the "all my files" feature of the Finder, but can happen on other platforms as well.

Anki does not have an explicit feature to combine decks, but you can accomplish this easily by moving all the cards in one deck to the other deck. Please follow these steps:

Some users who synced today may have encountered error messages, or files uploading again that were previously uploaded.

Apple changed the behaviour of iOS recently, which broke the formatting that older versions of the IO add-on were generating. The IO add-on maintainer has provided an add-on which should fix your existing cards:

Profiles are a feature designed to allow multiple people to study with Anki on the same device. They may also be useful for testing and other similar purposes, but this is not their primary purpose. Profiles are not recommended for dividing up your content, as doing so is unnecessary and limits your options in terms of viewing statistics and moving content around. Profiles are also unsupported on AnkiDroid.

Typical flashcards, both on paper and in Anki, have a front and

After you've used Anki for a while and downloaded some shared decks, you may end up with some note types with names like Basic-908e4 or Cloze-37a28. These note types are created when you download a shared deck that uses a note type with the same name as one that's already in your collection. (If Anki didn't do this, then it might merge two different note types that happened to have the same name.)

AnkiMobile's interface has been translated into a few different languages. Your iOS settings control which language AnkiMobile will appear in.

Sometimes you may want to "reset" part of your collection so that the cards become new again and the scheduling algorithm starts from the beginning. For instance, you might have completely changed a card or updated it so that you need to start learning it again, or you may have flipped through some cards without really studying if you were just trying to take a look at the cards or figure out how Anki works.

Sometimes users notice that text is appearing in front of or on their cards that they don't remember putting there. Usually it is just a couple of letters or nonsense. For instance, on the front side of your card you have written book, but when you review the card it appears as fybook.
