Before handing over your Spectacles to a friend, or posting them on eBay to try and make a few extra bucks, you should wipe the device of all your videos.
As we recently covered, Snapchat makes it easy to share your Specs with a friend or family member without exposing past recordings, but it only takes a few seconds to erase all videos from the glasses and provide extra peace of mind.
Prior to clearing your Spectacles, double-check that all videos are synced to your Snapchat account. Then go to Settings > Spectacles > Manage > Clear Spectacles Storage. A confirmation pop-up message will appear to give you one last chance to cancel out, or tap "Clear Storage" to get the process started.
A few seconds later, all videos stored on your Spectacles will be erased. You will still have access to previously recorded and synced videos in your Snapchat Specs album.
