If required, format the card in-device following the manufacturer’s instructions to ensure full compatibility and optimal performance. For use as app storage, set the device to use external storage or move supported apps to the card according to your device settings. Use the card reader or device connection to transfer files between the card and a computer.

Recommendations

For sustained 4K recording and best performance with high-bitrate video or frequent random reads/writes (apps, game data), use devices that support UHS-I bus speeds and enable proper formatting in-device. Keep backups of important files and use RecoveRx if files are accidentally deleted.
