Can anyone help with 'Slow SD Card' message and video recording stopping after 20 seconds.  Card installed is new genuine Samsung Evo+ SDXC 64Gb Class 10 UHS-1.  I have tested the speed and get circa Read 17.1MB/s, Write 10.1 MB/s.

Hello. We apologize if you're having issues with your SD card. Can you copy the files you already have inside and try to reformat the SD card?

Hi Wanda.  I have formatted the card on both a PC and in the Spark.

Will a UHS-3 card work in the Spark?

Watch this Video - I bought the Sandisk 64GB A1 U3 (Its for 4K but I like to have my Cards a Bit OverKill)

The Most Important thing is that for 1080p you use - 'Class 10' Cards

These are the compatible SD cards for Spark: https://www.dji.com/spark/info#downloads

I love to stick with SanDisk Cards, Never had 1% Problem in all my Photographic Equipment.

They cost more than other brands, but for 'STILL' under $100 you have a long term purchase.

Thanks guys.  Just back from the shop where as if by coincidence I purchased a Scandisk Extreme A1 UHS-3 V30.  Yes a bit of overkill for 1080p camera but it is working nicely now.  Having done some Googling it seems I'm not the first to have issues with the Samsung 64GB UHS-1 (as listed on recommended SD cards list).  I'll steer clear of that brand from now on.

Well done Sir

How many Slow SD Card messages did you receive? When I first installed my new Samsung card the Spark was reading similar message. I selected Format under the quick menu and reformatted the card. The message hasn't happened again since.
