In most cases，freezing problem is in relation with the quality of the memory card，firmware version, or the device itself.
As a preliminary excluding method，we advise our users to get your SD Card formatted either by your camera or by using your PC to makie sure it is an original branded card with best working condition. An inferior, fragile or low speed card can lead to the camera freezing.
SJCAM strongly recommends our end-users to purchase a reliable memory card from a credible seller - Please see our suggested brands in this FAQ section. Also please make sure to get an extra memory card for backup.
Meanwhile, if your camera is still freezing after the microSD problem is excluded, please check our website at www.sjcamHD.com for the newest firmware upgrades, which can be a fix to your issue.
