iPhone 7 Plus can take 4k videos, but if you click on the Photos app and upload to YouTube, for some reason it is limited to 240p. If you click on the YouTube app and upload, then it is 1080p.
Is there a way to upload directly from iPhone to YouTube in 4k resolution?
I think one way that will work is to transfer the video to the computer first, and then transfer from the computer to YouTube, but is there a way to directly do it on the iPhone, I wonder.
