Q1. What kind of Micro SD cards does ONE R support?
To consistently achieve the best results with your ONE R, you should use UHS-I Micro SD cards with a V30 or above speed class and exFAT format, or the shooting may stop and the footage may be damaged by the unmatched storage cards.
Note: UHS-II and UHS-III Micro SD/TF cards are not compatible with ONE R.


We recommend only purchasing name-brand microSD cards through official resellers. The cards below have been tested to work well with ONE R.

Q2. What is the maximum storage size ONE R supports?

Q3. How many minutes of video captured by ONE R can a 32GB memory card store?
In theory, one minute of 5.7K video is about 750MB, so a 32GB memory card is expected to store 43 minutes of video.
The actual storable duration may vary depending on the shooting scene or shooting mode, which can be viewed directly in the upper left corner of ONE R’s touch screen or viewed in the app after connecting to a mobile phone.

Q4. How to format the memory card?
If you want to format the memory card, please back up your files first and refer to the tutorial to format.

If the micro SD card has been inserted into ONE R, but the indicator light is flashing blue, please check the following points:

  1. Confirm that the micro SD card used meets the requirements of ONE R: UHS-I, V30, SDXC,and micro SD card in exFAT format;
  2. Confirm that the card is installed correctly;
  3. Please backup the file and tutorial.

Q6 Can I use a Lexar Micro SD card with ONE R?

If you have purchased a non-recommended V30 Micro SD card, please back up the files and format the card in the camera and try again.
