Sending watch frames to my Samsung gear S3

Good evening everybody,

a couple of month ago I’ve bought my Samsung S3 Gear smartwatch. Now that i’am a little bit more familiar with it, I’ve used Facer to create my own watch frame. I was able to send it from my PC to my Android phone and then to my Gear S3.
Is this the right way to proceed?

This is my second question: If I send another watch frame from the facer library, it always removes my previous own created frame on my smartphone and also my smartwatch. Is this normal? Thanks in advance for your help.
Kind regards.
