Mobile phone potato Video Watch record where to delete?

1 to delete the record of watching video we need to click on the potatoes to find "my" and then go into my interface there is a "watch record". (pictured below)

2 Then we click on the "Watch record" to enter and then click on the upper right corner of the "edit", and then we click on "Select All" and then click "Delete", if the pro want to retain part of the words, you can click the video behind the "√" can be. (pictured below)

All right, so all the records we've seen are empty. Oh, of course you do not delete all can also be deleted oh.
