The video I shot with Xiaomi 3 mobile phone can be opened directly at first, but I don't know why I need to download it to watch it. Why?

Because Xiaomi system automatically uploads the shot video to millet cloud service and deletes the video recorded on your mobile phone, it is recommended that you download it before watching it.

Expansion: millet cloud service, the cloud data synchronous backup function launched by Xiaomi Company on 20 12, allows users to back up all photos, contact information, short messages, communication records, notes, WLAN settings, APP lists and other settings in their mobile phones to the cloud, which can be accessed and modified at any time through mobile phones, tablets and desktop computers, thus enhancing the security and convenience of mobile phone data sharing.
