I have a Samsung frame because I wanted a TV that didn't look so much like I had one, but the software is so goddam bad. The only way to switch sources quickly is to set them as a favorite which isn't always that straight forward if you didn't do it right away. Regardless you have to let the the home page fully render before you can even worry about that. Even the Samsung TV app which you would think would be perfectly optimized for the hardware since the same compare makes the software is barely functional and loads like a web page on AOL in 1998
