Has anyone heard about sharing options for the 4K video? I wonder if we will be able to send 4K videos via sms? Im coming from the note 5 and whenever i send a 4K video to an iPhone, they receive it in very degraded form. I hope they find a way to fix this when sending 4K video from one iPhone to another. With the note 5, theres no way to lower the video quality once taken to be able to send.
