Topic: SD card not working?

Brand new switch. On 4.1.0

I purchased this card,

SanDisk Ultra 128GB microSDXC UHS-I card with Adapter(SDSQUAR-128G-GN6MA)

The switch says error 2016-0641 cant recognize SD card.

It works in my samsung phone, my asus laptop.

But does not work on my switch? Any reason why? Im afraid to buy another SD card to try.

I put in my standard 32gb microsd card in my switch and the switch sees it.

Well according to the following from the Nintendo Support FAQ page:

"
The following types of microSD cards are supported on Nintendo Switch:
microSD (up to 2 GB)
microSDHC (4 GB - 32 GB)
microSDXC (64 GB and above)
Important:In order to use a microSDXC card on the Nintendo Switch console, a system update is required.

In order to improve your gameplay experience, using a microSD card with a higher transfer speed is recommended.

High-speed microSD card guidelines:

UHS-I (Ultra High Speed Phase I) compatible
Transfer speed 60 - 95 MB/sec (the higher the transfer speed, the better gameplay experience on Nintendo Switch)
"
It should work. Switch maybe not updated?

Edit: did you also try to format it on the Switch? Or is that option not even available?

I tried to format it on the switch and it said it could not detect the card.
The switch is running the current 4.1.0 firmware.
Is there a way to tell if I have the update to allow SDCX cards?

I see that 4.1.0 is the most recent one. They have a page for this exact situation: http://en-americas-support.nintendo.com/app/answers/detail/a_... , but I think you won't like what it says.

Especially:
"
If after formatting the microSD card, it cannot be detected, the microSD card will need to be replaced.

Situation Not Resolved:
If multiple microSD cards cannot be read on the console, the console will need to be repaired. For testing purposes, be sure to include one or more of the problematic microSD cards that were being used with the console.

Have you tried to format it from your PC then re-format it from the Switch?
Sometimes weird tricks like that work for me on my phones.

There is a tool you can get from Nintendo to format the card:

I have a 200GB card from the same company so you should be fine with your card.
