Causes of Nintendo Switch 2016-0641 Error

The 21016-0641 error code normally occurs when there is something wrong with the microSD card inserted on the Nintendo Switch console. We have highlighted the common factors for the error below.

Incompatible microSD card.

Unlike other devices, the Nintendo Switch console can only use microSD cards due to its slot size. However, if the microSD card inserted is not supported, it will trigger the 2016-0641 error code. You must ensure that the card is compatible with the internal structure of the console to prevent any issues. For your reference, here are the types of microSD cards supported on Nintendo system:

  • microSD (up to 2 GB)
  • microSDHC (4 GB – 32 GB)
  • microSDXC (64 GB and above)

Damaged microSD card.

A microSD card can get corrupted if it is not properly ejected from the device or the card was removed while still transferring data. Once it is damaged, broken or corrupted, the error code will likely show up on the gaming console and will prevent you from accessing the stored files in the memory card or even play any game.  

Switch software is outdated.

The error code can also be a result of an outdated system. It is necessary to always update the system once available as developers include updates on the features, fixes on some known bugs and glitches and improvement of the console’s general performance.

Corrupted data in the Nintendo system.

Aside from the causes mentioned above, a corrupted file present in the gaming device can also be the main reason for the 2016-0641 error.
