Hi guys, my Osmo action camera cannot find the Samsung EVO select 256 GB SD card. Actually, it works at the beginning. But after I took a video more than 10 seconds. The camera will stop recording and report no SD card. Sometimes rebooting the camera will help. However once it starts taking a video, SD card crashes again. Is it the problem of the card or the camera? I have formated the SD card a few times use both the camera and a PC. Thanks

Hello hippo20, it is unfortunate to know about your Osmo action that is unable to detect the SD Card. Have you updated to the latest firmware? This link will direct you to the video tutorial on how to do firmware update:
Make sure as well that you are using the recommended SD card:
Osmo Action supports microSD cards with capacities of up to 256GB.
Recommended models:

Samsung Pro 64GB UHS-I SPEED GRADE 3 microSDXC
Samsung Pro Endurance 64GB UHS-I SPEED GRADE 1 microSDXC
Samsung Evo Plus 64GB UHS-I SPEED GRADE 3 microSDXC
Sandisk Extreme 16/32GB UHS-I SPEED GRADE 3 microSDHC

Other mainstream brands with a minimum writing speed of 30MB/s or above are also supported.
Please update me if the issue persist. Thank you.

Try another card and make sure it is a V30 so it is fast enough. And DO NOT buy from ebay, amazon or other places that sell fakes ones.
When I first got my OA I had a "fast" card Class 10, but it was not fast enough and made my camera stop recording after a short time, but after I bought a V30, I had no problem.

Thank you. I upgraded the software. The same problem came again. I think it’s the card cause other cards works fine.

Not sure about best buy either. I buy all my cards from photography retailers, to be sure to get the real deal.
